Set of goods according to tsd. What is a TSD data collection terminal? What are the advantages of using it

Modern logistics and trade processes are difficult to imagine without various automated devices and systems, be it a WMS system for warehouse management or various automated racks. The variety of equipment and device manufacturers provides the end consumer with a large selection and the opportunity to select equipment to suit their specific needs. One such device is a data collection terminal (DCT). There are many various types TSD from different equipment manufacturers. Below we will look at what TSD is, their types and their purpose.

What is a data collection terminal (DCT)

TSD is a specialized laptop computer designed for collecting data, processing it and interacting with the information system in an organization. This is a type of equipment for

The simplest modification is a cell phone-sized device with a built-in barcode scanner. The most complex models can operate underwater or at temperatures down to -50 °C. With the help of TSD, warehouse workers process turnover, ship consumable orders, or take inventory.

Operating principle of TSD

The principle of operation of the TSD is to read information by scanning a barcode and further transmitting this information to the information system.

Also, tasks can be issued to warehouse workers on the TSD screen, and if there are additional functions, the TSD can be used as a printer or intercom.

• Transferring information to the information system is possible wirelessly or by connecting the TSD to a computer via a cable.
• Some TSDs can be attached to the hand, and some are equipped with a pistol grip for easier operation.
• There are also industrial data collection terminals that scan specialized types of codes or operate under difficult external conditions.

How to use the data collection terminal

Using the TSD is quite simple; you need to point the laser scanner at the barcode so that the terminal reads the encrypted information. This information is then stored on the internal storage for subsequent transmission to the information system or transmitted directly via a wireless connection. Usually installed on the terminal itself special program for the TSD, which processes scanned information.

Also, tasks can be issued to warehouse workers on the terminal screen, and if there are additional functions, the TSD can be used as a thermal printer or intercom.

Using the terminal, you can carry out inventory, accept and ship goods, check the expiration date of goods, and check the correctness of price tags on the sales floor. When barcoding documents, the terminals can be used in document flow.

How does the data collection terminal work?

Transferring data to the information system:

After reading the information from the barcode, the data must then be transferred to the organization’s information system. For this purpose, data collection terminals are equipped with various data transfer interfaces.

• Some terminals are connected to the information system in real time and data exchange occurs via wireless communication,
• and some scan information to an internal storage device and subsequently transmit it when connected via a wire.
• It is also possible to transfer information via memory cards.

The main methods of transmitting TSD data:

• Connecting the TSD via a wired connection. Connection interfaces: RS232, USB. Sometimes a so-called cradle stand is used (a stand for a TSD connected to a PC). Several options for the operation of the cradle stand are possible - one-to-one (one base stand + one data collection terminal) and multi-point (one stand + several scanners). The advantage of a wired connection is the long battery life, because... there is no need to waste energy maintaining a communication channel. The disadvantage is the lack of constant connection with the information system and feedback.
• Connecting the TSD via a wireless connection. Connection interfaces: BlueTooth, Wi-Fi, IrDA (IR port), GSM. There are restrictions on the operating distance of the terminals: with a BlueTooth connection they work at a distance of up to 15 meters, Wi-Fi - up to 100 meters. IrDA is an infrared port, it works at a close distance of up to 10 cm. To connect via GSM, the information system must have a modem to receive the signal, it works in a stable signal area cellular communications. Advantages in permanent connection and feedback from the information system, always up-to-date information on the TSD. The disadvantages include a slightly higher price than wired terminals.

Scanner operation:

Modern barcode scanners differ in the type of reader, decodable codes, read capabilities QR codes and RFID tags.

The reading element device can be laser or LED.

• Laser TSDs are the most common and use a red diode laser. Scans standard linear (1D) barcode of various sizes (up to several decimeters).
• An LED scanner (image scanner) takes a picture of the barcode, and then analyzes and extracts the information.
• The image scanner can scan more complex barcodes (1D, 2D, mixed, damaged, QR codes) and operate at a distance of up to 15 meters.
• RFID tag scanners are not very widespread yet, but they successfully combine several technologies (barcoding and radio frequency identification). Can be used for marking expensive products.

There are also specialized scanners for recognizing codes made using direct marking technology (DPM). Application of a barcode is possible by drilling, laser engraving, etching with chemical reagents, extrusion (perma code) and other methods, depending on the type of surface. This type of coding is often used in industrial production. The operation of a simple scanner is complicated by the fact that the barcode is made on the very surface of the product, be it metal or polyethylene. Therefore, a special DPM scanner was developed.

operating system

The data collection terminal is a specialized mini-computer, with its own processor, RAM and long-term memory, and any computer must be controlled operating system. There are several such operating systems for TSD:

An old operating system, found mainly on older models and has a number of limitations. A DOS system generally runs only certain software developed by the device manufacturer. Software developed in programming languages ​​such as C++ or Visual Basic is also possible.

DOS terminals have a monochrome display, low computing power and internal memory storage. It would seem that such terminals are not in demand and are already falling out of use, but despite all the shortcomings, such TSDs have a number of advantages over more complex terminals. Low power consumption and, as a result, longer operating time on a single charge, system reliability, affordable price, which still allows us to compete in the equipment market.

• Windows

This is the most common and flexible operating system for a data collection terminal. Windows Mobile a more universal system, can be used in various modern terminals, but for this operating system there are higher system requirements. It is considered a more popular operating system because... A lot of applications have been developed for it for all areas of trade and logistics. Windows CE does not require significant computing power and is flexible in use.

• Android OS

A fairly new operating system that has recently appeared on the market of data collection terminals. It is characterized by ease of use, lower cost of developing applications for the terminal (compared to applications for Win), and the absence of complex licensing software. Interesting for small and medium businesses.

Relationship with WMS (thin client, thick)

To operate a data collection terminal, one device is not enough; you also need the appropriate software. This software (TSD driver) is developed for the operating system installed on the terminal. Large developers of their own corporate information systems are developing their own programs for TSD. Some equipment suppliers offer comprehensive solutions TSD + drivers for popular ICs (for example, for 1c). In general, there are two approaches to organizing the workplace.

Thin client based

For devices running the Windows operating system, the Remote Desktop Protocol or the Citrix Metaframe client can be used. With their help, you can remotely display the contents of the server desktop. You can also develop WEB applications to create a thin client. In this case, the “thin” client on the TSD will be any web browser supported by the system. For terminals running the DOS operating system, telnet can be used. In this case, the application running on the telnet server will be displayed on the TSD screen via telnet-client. Mode wireless connection ensures continuous communication between the TSD and the information system. This approach is considered outdated because equipment running DOS systems is becoming less and less.

Organization of a workplace based on a “thick” client

A “thick” client is an application developed specifically for a specific data collection terminal. The application can be developed for both offline and online mode. Modern operating systems in TSD (Windows, Android) allow you to develop various applications for the terminal. The disadvantages of a “thick client” are that it is tied to the operating system for which the application was developed. There is a risk of data loss if for some reason the data is not transferred to the information system.

Interface (sensor, buttons)

Used in various terminals various ways entering information. This can be a keyboard with a different number of keys or a touch screen, or a combination of a touch screen with function buttons is also possible. The number of buttons varies, both in TSD types and models. The advantages of a touch screen include the fact that any number of buttons and their combinations can be displayed on the screen. The disadvantages are that it is not always convenient to press buttons on a small screen; the accuracy of information input may suffer. Keyboards in terminals are also different. In the simplest version, these will be keys with only numbers. Some models have keys with numbers, each of which is assigned its own set of letters for enumeration, and there are keyboards with a full set of letters and numbers necessary for full input of information. The number of buttons in such terminals varies (12, 32, 53, etc.). A terminal with up to 8 function keys is considered convenient. There are terminals with a full qwerty keyboard, but these are specialized industrial models.

Additional features of TSD

• There are terminal models with their own characteristics.
• Some TSD models can be connected additional printer for printing barcodes, which allows you to print and replace labels if an error is detected in them.
• It is also possible to have a camera for additional photography of objects and entering information into the database.
• Some TSDs in the form of a PDA have a GSM module and can be used like a cell phone.
• Sometimes TSDs are equipped backup batteries small capacity and size. If the main battery is discharged, the backup battery allows you to save data and, if possible, transfer it to the IC.
• There are models with an adjustable laser angle for scanning barcodes, which reduces the muscle load on workers, and this affects labor productivity.

Battery, autonomy

One of the main characteristics of TSD is battery life. Naturally, the larger it is, the better. At a minimum, the TSD should be enough for one 8-hour work shift, and some models, with a larger battery capacity, work up to 24 hours without recharging. Most models of data collection terminals are powered by Li-ion or Li-pol batteries. The rest are from regular alkaline batteries or other types of batteries. Some TSD models come with removable batteries that can be hot-swapped. The advantage of this is to ensure uninterrupted operation, but as a result, the price of such models is higher.

Temperature conditions, protection

There are specialized scanners that can operate in a wide temperature range, from -50 °C to + 50 °C. They have enhanced protection from the external environment, a durable housing, sealed connectors, and a screen with impact-resistant glass. The TSDs are also equipped with enhanced sound and light indication for operation in conditions of increased noise and limited visibility. The scanners have a rubberized body and can withstand repeated drops from a height of up to 2 meters. Such scanners have a protection class, which is determined by the international standard IEC 60529, designated IPXY (X is the degree of protection against the penetration of foreign objects and dust. Y is the degree of protection from moisture).

Types of TSD brief overview

Data collection terminals can be divided into several generally recognized categories. There are also many different companies producing TSD. There are also separate services that repair TSD.

• Entry class TSD, equipped with a simple barcode scanner and a small number of function keys. Designed for small organizations. The data obtained as a result of reading barcodes is stored on the device and later transferred to the information system via a wired connection. The setup of such TSDs is minimal.

Advantages: low price, ease of use, reliability.

Flaws: lack of computing power for complex warehouse operations, little functionality, need to connect to a computer to transfer data.

Many companies produce entry-level TSD

• TSD with handle– a special type of terminals that are distinguished by an attached pistol grip for ease of use. Handle-mounted LCDs often have a long-range barcode reader that operates up to 9 meters away and can scan through glass, allowing forklift operators to read codes without leaving their seats.

Advantages: ease of use, protection from the external environment, all the functionality of full-size TSDs.

Disadvantages: price.

TSD with handle

• Wearable TSDs are attached to the wrist, leaving your hands free, and the ring-shaped laser scanner is placed on your finger. Maybe voice control. A very convenient device when workers need to have their hands free while scanning.

Advantages: ease of use, protection from the external environment, all the functionality of full-size TSDs.

Flaws: price.

What TSD (), how to use it, and under what conditions these devices are needed, should be presented to those who are going to set up a computerized system for recording the movement of goods in their trading enterprise.

The basis of the entire information system is to supply all goods received in a store or warehouse with barcode labels, which contain all information about the product in encoded form. Some products arrive with a barcode printed on the packaging, while others are provided with such labels already in place.

At the time of sale, the terminal installed at the cashier’s workplace, using a scanner included in its structure, reads the information and transmits it to the base computer, which stores a program that takes into account the movement of goods.

But it’s not only at the checkout that you need to have information about the product. It is necessary to register all incoming goods, track their movement to the sales floor, and during inventory it is necessary to check the list quantity of goods with their actual availability.

That's what a data collection terminal is for - tracking the movement of goods. You need to have a good understanding of how to work with the data collection terminal and what functions it performs.

Device functionality

If you look at any data collection terminal, its operating principle is . This is how the accounting system receives information about what products are available. But in order for her to receive all this, she must first decode the barcode, which requires the efforts of a laptop computer, and then contact the base computer wirelessly and transmit this information.

Barcode scanning

The use of a data collection terminal for scanning can be based on various scanning technologies. You can illuminate the barcode in order to analyze the reflection using LEDs or a laser beam. The latter method is more efficient and can distinguish smaller images.

By its design, the scanner can operate in one plane - then the device must be brought to the barcode, oriented precisely. Multiplane scanners work at any angle to the barcode and to the surface on which it is printed. They can perceive two-dimensional codes that carry an increased amount of information.

Computer component

The first question asked by a merchandiser who picks up a TSD (data collection terminal) for the first time is: how to use it? There is no particular difficulty in using this device: the built-in processor does everything automatically. The ability to enter information from a keyboard or touch screen is necessary mainly to correct the read barcode if its damage leads to an error during scanning. Then you can correct the technique by entering the required numbers manually.

Having read the code, the device processes it, decodes it, and in this form transmits the information to the base computer. Another function is storing information. If you had to use the device beyond the communication capabilities, the processor gives a command to switch to offline operation - in this case, all scanned barcodes are stored in memory and only after communication is restored, they are transferred in a common package to the host computer. Nothing is lost.

Wireless Capabilities

The Bluetooth wireless interface reliably connects the mobile and base processors at a distance of no more than 10 meters. In a small warehouse this may be quite enough. If we're talking about For large warehouses where the merchandiser has to move around 100 meters or more from the base, it is best to use a different interface – Wi-Fi.

How to link two computers

Organize wireless communication- not enough yet. It is important that the software is reliably connected to each other. A basic computer running on an operating system Windows systems, usually easily recognizes the connection of a data collection terminal and perceives the transmitted information without loss. If inconsistencies are found at the software level, you have to use a special driver, sometimes it is even developed by a programmer.

When everything is ready

So, the company’s commodity experts received a DCT (data collection terminal) and were told how to use it and were given training. You can start working - just go through all the products and swipe the device over the barcode. Working with the data collection terminal is extremely simple - the only task is not to miss anything. Employees quickly get used to it, and the inventory process speeds up many times.

The use of a data collection terminal makes it possible to minimize the participation of the so-called human factor when carrying out inventories, acceptance and release of goods. Automatic processing and transmission of information contributes to a significant reduction in the number of errors, which ultimately leads to improved organization of work and reduction of time losses.

Electronic TSD is used:

• when conducting inventories;
• upon acceptance, release and internal movements of goods;
• to check price tags on the sales floor;
• to serve customers at the checkout in offline mode (to speed up service) with the issuance of a receipt.

The functionality allows you to upload data either when installing the terminal in a “socket” connected to the system, or directly at the time of scanning.

If it is necessary to expand the range of options, additional software is installed that allows you to analyze the product range, manage operator actions, and place pre-orders.

How does the data collection terminal work?

During the scanning process, data is accumulated in the terminal’s memory or immediately transmitted to the central port via a radio channel (depending on the model).

The TSD is connected to the computer using a special communication stand, which simultaneously serves charger for the terminal. It is also possible to transfer and exchange data with using Wi-Fi, Bluetooth, infrared or USB (depending on the features of the retail equipment).

Radio terminals are used in cases where continuous uploading of data to a central system is necessary. At the same time, the information is immediately processed and allows you to quickly eliminate any miscalculations and errors that have arisen. In fact, the radio terminal acts as a common part unified system. The devices are used in large warehouses, hypermarkets, distribution centers, and factories, making it possible to reduce time losses and have real information about the movement of items in real time.

How to choose a data collection terminal

The correct selection of electronic TSD for a warehouse guarantees uninterrupted work on collecting and transmitting information to the central system, thereby ensuring the stability of control and accounting processes.

When purchasing a terminal, you should consider the following parameters:

• Compatible with the operating system of the main commercial equipment. At using Windows CE, Windows Mobile, it is possible to work with a touch screen, receive color and graphic images. The DOS system is installed on terminals with a monochrome display and provides information only in the form of text; such TSDs differ long term work without recharging (up to one day).
• Software. Must be consistent with the ability to integrate TSD into a centralized system. The most functional and reliable software include SOTI MobilControl, Logistic Solution, 1C, CITYSOFT Warehouse.
• Data Collection Format– linear barcodes or PDF417, electronic signatures, radio frequency tags.
• Functionality and room size– sales area, warehouse, distribution center.
• Special working conditions. To use terminals in industrial conditions, additional protection from dust and moisture, the ability to operate at low temperatures (up to – 30°C), and an impact-resistant housing are required. Parameters such as distance from the scanned object, the presence of sunlight, glare from glass and plastics are also taken into account.

Specialists in working with commercial equipment recommend purchasing electronic TSDs produced under the brands of well-known brands - Motorola (Symbol), Casio, Datalogic, Opticon, Pidion, Honeywell, which allow you to quickly upload or transmit information online to a central system.

It is not easy to abandon the usual way of conducting warehouse processes. However, with the development of technology, there are opportunities to optimize them, reducing the amount of time spent on solving problems and the number of operational errors arising as a result of the human factor. One of the striking examples of such optimization is the use of a data collection terminal (DCT), which allows you to “playfully” carry out the acceptance, inventory and shipment of goods.

Any warehouse, regardless of its specificity or size, has to solve three mandatory tasks: acceptance, inventory, picking and shipment of goods from the warehouse. Many warehouses, despite advances in technology, still perform these three tasks manually. Not only are the processes slow, but also during their implementation there is a high probability of operational errors occurring. To negate the impact of these disadvantages on warehouse operations, there are two ways.

First, organize a workstation, whose role is played by a regular computer on which the warehouse Information system and a barcode scanner is connected. The advantage of this solution is that the problems stated above are actually eliminated. However, instead of them, others appear - warehouse processes become tied to a specific zone. This means that, for example, when receiving, it is necessary to bring all goods to the workstation so that a warehouse employee can scan them and enter them into the database. If the warehouse is small and there are not many products coming in, then this route is quite acceptable. However, if we are dealing with a warehouse company big size, then being tied to a workstation becomes cumbersome.

The second way is the introduction of data collection terminals (DCTs). This option, like the first, eliminates the disadvantages of manually performing tasks and also ensures mobility in the implementation of processes. At the same time, with the development of technology, the cost of data collection terminals has become relatively low: an inexpensive TSD will cost approximately 25.5 thousand rubles, the cost of an average device will be from 38 thousand rubles. Moreover, one such device can perform not only the three tasks we have listed, but also many related ones. For example, they are capable of operating in walkie-talkie mode if you connect a headset to them - many manufacturers provide this option, including Zebra, Datalogic, Honeywell. TSDs can also be used as a task manager, even by installing an email client on them.

However, it is not enough to purchase a data collection terminal - it is important to equip it with high-quality software. Here retailers take three paths.

They write software for TSD themselves and prepare applications for each task. This method is not always convenient, since the number of tasks grows by leaps and bounds. Accordingly, we have to spend more and more time writing applications.

They order software written to suit their needs from developers. Here you also have to face a number of inconveniences: a small company is not always able to quickly make changes required by the customer. In addition, constant improvement of the software can cost a lot of money.

Purchase an industrial solution. In this case, it is important to consider whether the developer is Russian or foreign, since in the second case, given the current situation on the market, it is difficult to avoid currency risks. In addition, it is difficult for foreign developers to quickly adapt software to changing requirements Russian legislation. On the other hand, not every domestic company has the same expertise as its foreign colleagues.

But no matter which path the warehouse owner prefers, he in any case needs to take into account the following basic requirements for software for TSD.

The software must be able to work both online and offline. Working with the device in offline mode ties the user to the workplace: he will have to manually upload data for accepting the invoice to the TSD and after that go to work. In online mode, the invoice is sent to the device regardless of where it is located. However, this requires organizing wireless network and a stable communication channel, and this is not always possible: for example, due to the many metallized surfaces often present in the warehouse.

The software must be modernized as the business develops: the warehouse owner needs the ability to modify the software for TSD depending on growing requirements. Therefore, in many industrial solutions, either numerous applications “for all occasions” already exist, or the ability to quickly create them is included. For example, in our OmniLink there is an “Application Generator” - a kind of constructor with the help of which a user can create the application he needs without programming.

Software for TSD must be equipped with tools for integration with external systems, allowing it to receive data from there. The more integration tools, the better, the more flexible they are, the more opportunities the data collection terminals will have.

Task No. 1: goods acceptance

The first task that any warehouse inevitably faces is the acceptance of goods. In manual mode, it works like this: a warehouse employee prints out an invoice and uses it to check which goods and in what quantities have arrived. With TSD, the process looks different: an invoice is uploaded to the device, and the employee simply scans the barcodes of the received goods in a row. As a result, a list of incoming products is generated, after which it is sent to the external system. At the same time, the data collection terminal allows you to generate and send both a list of actually received goods and a list of discrepancies with the invoice. As a result, the warehouse worker does not have to look for goods and count them manually.

One example from our practice. The process of accepting goods from one of our customers after implementing a mobile solution began to take 6 times less time. A task that was previously performed by 3 people within an hour is now completed by one employee in 20 minutes.

Task No. 2: inventory of goods

The manual inventory method is not much different from acceptance: a warehouse employee prints out a list of goods that, according to an external system, should be listed in the warehouse, and checks it, walking around the entire premises, looking for the necessary products and recalculating their quantity. If the warehouse is small and there are 10 items in it, then this path is quite possible. Otherwise, the inventory process takes a long time, and its implementation is not without operational errors.

With TSD, the worker simply scans the barcodes of all products that come into view. And his software itself generates a list and sends it to the external system. In this case, the data can be either listed or indicated in what quantity each product item is presented.

Since in some cases inventories are broken down by area, TSD can create such a list, linking goods to storage locations. In addition, the warehouse owner receives data about which employee carried out the inventory and at what time. This is necessary if he wants to control the operator’s area of ​​responsibility.

Example from practice. For one of our customers, using the “manual method,” the process of complete inventory of 30 stores took two weeks. After purchasing the TSD, this time was reduced to one week. He bought only two data collection terminals and simply transports the devices from store to store. Thus, it became possible to inventory 4 stores in one day. Data from each point is transferred online to an external system. During the first full inventory with TSD, some goods were discovered that had long been written off from the warehouse, as they were lost during manual inventories.

Task No. 3: picking and shipping goods

This task is most relevant for warehouses associated with online stores. In manual mode, when receiving an order, the employee has to print it out and go look for where the required products are located in the room, and then return to the workplace and enter the received data into the system. As a result, order processing time takes a fair amount of time.

With terminals, the process is much faster: the external system sends the order list to TSD. The device shows the warehouse worker exactly where the desired product is located. All he has to do is go to the specified location, scan the barcode of the product and pick it up by placing an order. At the same time, TSD sends a notification to the external system that the order is ready, and it, in turn, sends a letter to the customer that he can come for the purchase.

Example from practice. Another client of ours, a large online hypermarket, has implemented data collection terminals in the warehouse and reduced the customer’s waiting time at the delivery counter from an average of 10 minutes to one to two minutes.

In addition to the three processes listed, TSD can solve many necessary problems. For example, carry out labeling of goods. One of our clients supplies the same products to several retail chains. Accordingly, each of the networks has its own barcodes, different from those that mark the goods in our client’s warehouse. At the shipment stage, the operator completes, say, 20 packages of products, scans their internal barcode and selects at the terminal for which network these products are intended. Thus, the TSD gives the command mobile printer print new labels with the required (correct) barcodes.

Let's give another one of our business cases with an auto parts store. Some products arrive in packages, so they need to be marked individually. To do this, when receiving the goods, the employee scans the barcode of the general packaging, on the basis of which TSD generates a label for each product.

Working with a data collection terminal significantly reduces the time spent on warehouse processes, and also reduces to zero the number of operational errors that appear as a result of a manual approach. However, it is important to consider in advance exactly what tasks the TSD will solve and select the appropriate device and software for it.

A data collection terminal (DCT) is a popular and often irreplaceable device in a modern trading enterprise. Let's get acquainted with the specifics of its purpose and with the features of choosing a TSD model suitable for specific tasks, taking into account a fairly large number technical characteristics of this type equipment.

What is it and how to use TSD

Data collection terminal is the traditional name of a device that is used in managing a trade or warehouse, and is a relatively small (designed for manual use) gadget, adapted to:

• to reading various barcodes (in which information about products is encrypted);
• to transfer the read data to some external computing module (as a rule, to write data to the built-in memory, in many cases, to process this data using built-in computing modules).

It is possible for a long period of preliminary placement of the collected information inside the terminal, and then “batch” data transfer to the external module at a set frequency. But such transmission in real time is not excluded (and, moreover, it should be considered as one of the typical scenarios). Depending on the specific tasks of the trade or warehouse management process, a specific method (or combination thereof) of data processing is selected.

Thus, the main functionality of the device fully corresponds to its name: the terminal is designed to “collect” the required data in a certain way (in practice, scan a barcode in which this data is encrypted). This function is inextricably linked with another - the function of ensuring further processing of the “collected” data - in internal or external modules.

In practice, the terminal - for example, in a warehouse, can be used to compare the actual quantity of goods received with their quantity according to the invoice (or other accounting documents). For these purposes, an invoice file is registered in the terminal’s memory in the prescribed manner (or a connection is provided with this file located on external media), with which the data received from the device’s scanner is then verified. As soon as all the goods actually accepted by the warehouse employee are scanned on the TSD, and information about them is compared with the file, the warehouse program will determine the degree of correspondence of the data between the file and the scanner. If there are discrepancies, the TSD user will be notified about this (and this notification will list missing items - or, conversely, extra ones for which there is no data in the invoice).

Thus, the data collection terminal is, in general, a control tool. There is a certain standard number of objects taken into account, and there is an actual number - based on the results of operations with these objects. Using TSD, data on both parameters are compared. Then, based on the information received, the company’s employees carry out necessary actions(aimed at eliminating discrepancies or otherwise provided for by instructions or orders of colleagues).

The main areas of use of data collection terminals are as follows:

1. Carrying out operations related to:

• with the movement of goods throughout the warehouse, between the warehouse and the sales floor;
• with inventory of goods;
• with control of price compliance for goods.

1. Documentation accounting, control over the correctness of the data reflected in them.

The functionality of the data collection terminal may involve various “feedback” options, which involve displaying information on the device screen in response to a particular reading operation. For example, a detailed display of data about a scanned product (its characteristics, quantity, location) - which can be used by a store or warehouse employee for various purposes.

Other useful functions that many modern data collection terminals are equipped with include their suitability for use as cell phone or walkie-talkies, as a device for accessing the Internet - if the capabilities of the software allow, as a network messenger in an enterprise. In general, the functions of many modern TSDs are close to those that characterize modern mobile gadgets - in essence, terminals become their variety (which, at the same time, is used to solve highly specialized problems).

Thanks to the presence of a built-in scanner, the data collection terminal can be used in those areas of the store organization where scanners as such are used - for example:

• at the checkout - in order to speed up data entry into the cash register computer when generating a check;
• in the sales area - in order to obtain information about the price and other information about the product at the buyer’s request.

Due to the fact that the data collection terminal is usually built into a single information base enterprise - at the software level, no additional complex configuration is required. The device quickly integrates into the current infrastructure at the checkout or on the sales floor.

In some cases, TSD may find application outside the trade sphere. For example, when recording correspondence and parcels at the post office, cargo and vehicles at various transport infrastructure facilities.

How data “collected” on TSD is processed

The TSD can connect to an external computing module - which processes the “collected” data different ways- wired and wireless. Data collection terminals with Wi-Fi and those adapted for data transmission via Mobile Internet. But at localized workplaces - for example, when receiving goods into a warehouse, a wired connection of the terminal to a warehouse computer is a completely workable option. There are terminals optimized for placement on cars and special equipment.

Information read on the TSD can be processed on an external module for different purposes and using different software. The use of popular modules is common warehouse accounting 1C and their competitors - that is, those solutions that are being implemented to automate trade and warehouse management. And the TSDs themselves thus become part of the toolkit for such automation.

What are the advantages of using it

So, regardless of the specific method of using the terminal, its main purpose is the automation of a particular area production process. In the absence of a data collection terminal, a store or warehouse employee would have to perform the same accounting procedures - but only manually.

Thus, TSD is, first of all, a tool for saving staff time and labor. According to a number of experts, appropriate automation on average speeds up key warehouse and inventory operations up to 5 times - compared to the time required to carry out such operations manually. In addition, the need for a large number of employees in those areas where such operations are carried out is reduced.

Data collection terminals, unlike humans, operate error-free (provided, of course, that they are configured correctly in both software and hardware). Matching errors will be minimized different types data, compiling registers, checking various indicators with which people work in sales and warehouse management areas.

The use of data collection terminals allows for more effective control over the work of employees in the relevant areas. The controlling person - the warehouse manager or his immediate supervisor - can implement programs at the enterprise that allow tracking of each operation carried out using TSD. This will avoid uncontrolled movements of goods - each of which will be taken into account in this program. The level of personal responsibility of warehouse workers increases: the likelihood of goods leaking to the outside, replacing it with low-quality goods, or causing a breakdown (with subsequent inaction in eliminating it) will be minimized.

Design and technical characteristics of TSD

A data collection terminal is usually a small device, the size of an average smartphone, designed primarily for portable use (but there are also stationary TSD models). Many modern TSD models are adapted for use in difficult temperature conditions and have a durable housing that is resistant to external mechanical influence.

The terminal can be controlled using a built-in keyboard or touch display - more and more modern TSD models are equipped with it. It is, of course, possible to use a combination of different device management tools.

From the point of view of hardware capabilities, the data collection terminal is a very productive computing solution. In some cases, its characteristics are comparable to computer ones or those characteristic of modern mobile gadgets. A typical combination of the following hardware components for an average-priced TSD is:

• processor with a frequency of 1-1.5 GHz;
• RAM of about 256 MB;
• built-in memory up to 32 GB (expandable using plug-in memory cards).

A typical display that terminals are equipped with has a vertical orientation, a diagonal of about 3-4 inches and a resolution of about 480 by 800 pixels.

Video - connecting the data collection terminal to 1C:

TSD can be equipped with various types of scanners. Most often this is:

• laser and LED scanners (installed mainly on budget terminal models);
• photo scanners or image scanners (installed on more expensive devices).

Laser scanners are usually cheap, however, they have the disadvantage of being limited in their ability to read erased barcodes. Photo scanners are generally very good at recognizing even low-quality, dull barcodes.

LED scanners represent a solution that can be considered a kind of “compromise” between laser and image scanners. On the one hand, an LED scanner is approximately the same price as a laser scanner. On the other hand, it has a number of technical advantages over it, especially in terms of:

• scanning barcodes on deformed (crumpled, scratched) paper;
• scanning barcodes on glossy surfaces;
• reading colored barcodes (for example, red).

Laser and LED scanners are approximately equal in their capabilities when reading data from barcodes:

• highly readable, printed on undamaged surfaces;
• small size (with narrow stripes).

In turn, laser scanners are certainly superior to LED scanners in scanning barcodes at considerable distances - more than 30 cm. Imaging devices are also adapted to reading codes at a similar distance.

Note that the rule “laser is a cheap TSD, image is an expensive TSD” has exceptions. There are high-tech laser scanners adapted for installation on premium models of data collection terminals. Their ability to read low-quality barcodes can be at a fairly high level.

There is a special subtype of scanners for TSD - RFID devices. They are designed to read data at a great distance from the scanning module (sometimes up to tens of meters). This data is generated using special radio tags. As a rule, RFID scanners are in demand at large cargo terminals, ports, and industrial enterprises.

Video - how to use the TSD data collection terminal in 1C Trade Management:

A typical data collection terminal has a built-in battery that can provide autonomous operation for 8-16 hours (with recharging time from zero about 8 hours).

In terms of software, modern TSDs operate, as a rule, under special modifications of the Android and Windows OS, and sometimes DOS. Less often - factory firmware. Thus, you can install special applications on the terminal (or implement software algorithms based on existing applications), which adapt it to the solution various types production tasks.

How much does a data collection terminal cost depending on the type of TSD?

A common classification of data collection terminals is the following main types:

1. Storage devices.

Their main feature is their ability to accumulate a large amount of data on operations that characterize the operation of the production site where the terminal is used. In many cases, this data can be edited in the prescribed manner, supplemented with others, and used as an object for analytics.

1. Broadcasting devices.

Their main purpose is the rapid transfer of data to external computing modules - where, as in the case of devices of the first type, they can be accumulated and used in various ways.

At the same time, in the modern market of data collection terminals, more and more solutions are appearing that essentially combine the functions characteristic of the two indicated traditional types of TSD. Thus, the above classification of terminals should be considered very conditional - just like, for example, their traditional division:

• according to the degree of adaptability to movement (optionally, based on the capabilities of the battery) - into mobile and stationary;
• by the method of data exchange with external devices- wired and wireless.

The fact is that many of the modern terminal models, firstly, are extremely difficult to classify according to the above criteria (since they are essentially universal), and secondly, the classification specific model A TSD for one type or another may not give anything in terms of determining the degree of its compliance with the tasks that are typical for the production site where the terminals are planned to be used.

The classification of modern TSDs according to the following basic criteria can be quite useful:

1. Operating system level .

Here you can select terminals:

• single-tasking (with DOS, with factory firmware);
• multitasking (under Android control and Windows).

Indeed, data collection terminals with a single-task OS are designed to solve only the task that a warehouse worker faces immediately at the time of using the terminal. It cannot use any parallel functions of the device. In turn, these functions can be applied to multitasking TSDs. For example, along with scanning a product, a warehouse worker can view the current balances of such a product on the screen.

Despite single-tasking, terminals of this type are in demand because, in turn, they have many advantages over multi-tasking ones, for example:

• stability in operation (on a single-tasking OS the likelihood of freezes, crashes, and virus infections is minimized);
• speed of operation (carrying out a computing operation in a single-tasking OS requires adaptability to perform tasks using much less processor and memory resources - as a result, the device can be equipped with the most budget microcircuits, which reduces the overall cost of the terminal).

Thus, a single-task TSD is, in fact, a “TSD in its pure form”, performing all of its key functions- but at the same time cheaper in comparison with multitasking devices.

Among the popular single-tasking terminals on DOS is the Casio DT-970 device (cost - about 25,000 rubles). For comparison, its functional analogues from among the budget multitasking TSDs can usually be purchased for no less than 28-30 thousand rubles (Proton PMC-2160, PMC-2260 devices).

At the same time, multi-tasking terminals, for obvious reasons, have a higher adaptability to integration into the company’s existing commodity accounting infrastructure. At the level of a full-fledged OS - Android or Windows, it is almost always possible to implement required applications to integrate TSD with commodity accounting infrastructure.

Thus, in the PMC-2260 device, fast integration with EGAIS is implemented at the software level (while ensuring data transfer to it from single-task TSDs in many cases requires the development of separate software interfaces- which in most cases is not economically profitable).

1. Supported Barcodes .

Based on this criterion, data collection terminals can be classified in the most general case:

• to devices that support scanning 2D codes;
• to devices that do not support such scanning.

A common type of 2D code is a QR code. Regular codes are with “stripes”, these are 1D codes.

Adaptability to reading 2D codes requires the terminal to be more technologically advanced - especially in terms of processor performance (since the information “encrypted” in a two-dimensional code is, as a rule, incomparably more complex than that written in a one-dimensional code). Therefore, the difference in the price of TSDs - those that support and those that do not support scanning complex codes, can be noticeable.

For comparison - one of the cheapest single-tasking terminals with support for scanning 2D codes - CipherLab device 8200, costs about 56,000 rubles, that is, more than twice as expensive as the Casio DT-970 device. At the same time, cheaper devices can be found in a number of multitasking TSDs. For example, a Datalogic Memor X3 device on Windows OS costs about 43,000 rubles.

1. Adaptability to work in difficult conditions .

Thus, we can distinguish data collection terminals:

• adapted to difficult climatic conditions - for example, at low temperatures;
• having a shock-resistant body;
• resistant to moisture.

Among the most “frost-resistant” devices are the solutions from the CipherLab line - devices 9730L (71,000 rubles), 9700L (75,000 rubles), CP60L (84,000 rubles). All of them are capable of operating at temperatures from minus 30 degrees.

The most protected from falls are the Casio devices DT-X200-10E (66,000 rubles), DT-X200-11E (71,000 rubles), DT-X200-20E (85,000 rubles). All of them can withstand falls from a height of up to 3 meters.

The most waterproof devices have an IP67 index. There are quite a few of them, and one of them includes the well-known budget terminal Casio DT-970. According to the criterion of moisture resistance, therefore, there is no correlation with a high price - this is a universal TSD parameter.

1. Type of scanner used in TSD .

This is the most important and at the same time very controversial criterion. We noted above that when general rule- when a laser scanner, which is cheaper in comparison with a photo scanner, is inferior to the second in terms of adaptability to recognizing low-quality barcodes - there are exceptions in the form of technologically advanced laser devices, which work very effectively in recognizing such codes.

For example, the premium RFID terminal Zebra MC3190-Z (its cost is 257,000 rubles), at the user’s choice, can be equipped with either a 1D laser scanner or a 2D photo scanner (despite the fact that all configurations cost the same). Thus, under certain technological conditions, a “cheaper” recognition technology may be more necessary than a “more expensive” one. But here we are talking about a very narrow scope of application - nevertheless, the specified scanner from Zebra is a typical industrial RFID solution, and the specifics of its use should be carefully transferred to other areas.

Regarding the “cheapness” of a laser (or LED) and the “expensiveness” of an image, not everything is clear either. Of course, the general price trend - according to which laser or LED TSDs, all other things being equal (taking into account exceptions - using the example of a device from Zebra) are cheaper than those on which a photo scanner is installed - is still relevant. But, firstly, the difference is still not astronomical. For comparison, one of the cheapest TSDs with a photo scanner, the Proton PMC-2260 device (32,000 rubles) costs a little more than the cheapest Casio laser terminal. There are other inexpensive models with a photo scanner - for example, Honeywell EDA50k (34,000 rubles).

Secondly, it cannot be stated that there is a direct relationship between the type of scanner that is installed on the TSD and the device’s ability to recognize a certain type of code. Of course, image scanners are the most versatile. They read any type of codes. At the same time, there are many terminals with a two-dimensional laser scanner - for example, Zebra MC2180 (45,000 rubles), Datalogic Skorpio X3 (76,000 rubles).

Thus, if the process of using the terminal involves reading two-dimensional codes, a device with a laser reader that supports the recognition of such codes may well be used for these purposes. If desired, in most cases you can find the closest analogue of such a TSD in price - but only with an image scanner, since in practice the difference in the cost of devices, as a rule, is not large with other comparable characteristics.

Note that LED TSDs adapted for reading two-dimensional codes are a very rare occurrence. In this sense, terminals of this type are much inferior to laser and image ones.

But if scanning 2D codes is not expected, then an LED terminal will be an excellent alternative to a laser TSD. As we noted above, LED devices can be more effective when reading codes on deformed paper or glossy paper (but are inferior to a laser when reading codes at a distance). Examples of budget devices with an LED scanner are the single-tasking terminal CipherLab 8200C (25,000 rubles), the multi-tasking CipherLab RS30-C/R (43,000 rubles).

Many TSD models have two modules preinstalled at once - for example, a one-dimensional laser and a two-dimensional imager. Thus, the type of TSD scanner is a criterion for which it is very difficult to identify universal patterns in terms of application practice. Each time you need to look at the specific conditions of use of the data collection terminal, the characteristics of the scanner (or scanners) preinstalled in it, and its suitability for installing the necessary scanning modules one by one.

But if we still try to identify some patterns in the use of scanners, then very conditionally we can state that:

• for scanning barcodes that are regularly located at a large (more than 30 cm) distance from the TSD scanning module, laser and image scanners are best suited;
• to read barcodes, which due to the specifics of the production process can sometimes be damaged and become unclear - image scanners are best suited;
• For scanning barcodes on glossy, deformed surfaces, image scanners are optimal, and if budget is limited, LED scanners are optimal.

LED terminals are in most cases not suitable for reading 2D barcodes.

It should be noted that in many TSD models - and this rule characterizes both budget and more expensive solutions - the installation of a scanning module of a specific type at the user’s choice is provided. You can purchase two modules at once (as a rule, this is a pair consisting of a laser and an image scanner) - and then, if necessary, use the first or second.

1. AvailabilityRFID-module .

The criterion under consideration has a low position only from the point of view of the likely narrowness of the scope of application of the device (which is due to the presence of an objective need for an RFID terminal in a small percentage of enterprises). However, in relation to the corresponding narrow area, the presence or absence of an RFID scanner as part of the TSD is indisputably the most important parameter that will come first.

Video - bag inventory using RFID data collection terminal:

In practice, RFID modules are used, as we noted above, at large cargo terminals and in industry. These are very technologically advanced hardware components - and their installation in a TSD quite significantly increases their cost. But you can also find fairly inexpensive RFID solutions. For example, the Casio IT-G400 multitasking terminal on Android based(cost - 60,000 rubles).

1. Availability of additional communication accessories .

For example - a microphone, a built-in camera. These accessories can be used for communication and exchange of information between warehouse employees who work at a distance, and, moreover, due to the work performed, feel the need to use such means of communication.

Examples of devices that have both a microphone and a camera are Casio DT-X30 (46,000 rubles), Honeywell Dolphin 60s (53,000 rubles), Proton PMC-1100 (63,000 rubles) terminals.

How to choose TSD for your needs

There are quite a lot of criteria for choosing the right data collection terminal (taking into account the variety of technical characteristics of the device discussed above). Which of them are considered the main ones can be determined according to the “industry” principle.

For example, a terminal used in a freight warehouse will most likely not be used for anything other than its core functionality - which is to scan barcodes (almost always 2D in such cases) and transfer the data to an external computer. module for post-processing. Therefore, in the case under consideration, the cheapest single-task terminal with a one-dimensional laser reader will be optimal.

However, if the warehouse is open and located in a cold region - as an option, in one of the ports of the Northern Sea Route, where minus 30 is almost a resort temperature, then, most likely, TSD, at least in winter, will be be regularly used in extreme climatic conditions. In this case, attention will have to be paid to a frost-resistant terminal.

Video - webinar on how to choose a data collection terminal:

In turn, in industrial production and construction there is an obvious need for TSD that is resistant to mechanical stress. When working with cargo on an industrial scale, it is obvious that you will need a high-tech RFID device.

If the terminal is intended to be used in a sales area, then, most likely, the matter will be limited to the use of its most basic functions - reading data from barcodes (probably one-dimensional) and simultaneously transmitting them to the goods accounting system. This task, again, can be handled by the most budget-friendly, not necessarily frost-resistant and protected, single-task terminals with a simple laser scanner.

The leading brands producing TSD include the following companies:

• Casio;
• Datalogic;
• Honeywell;
• Proton;
• Zebra.

Produces excellent terminals Russian brand ATOL. Among them is one of the most affordable multitasking 2D terminal ATOL Smart.Lite (costs 19,000 rubles), a MobileBase DS5 device with two scanners - laser and image (71,000 rubles), secure terminal ATOL Smart.Droid 1D / 2D (29,000 rubles).

An argument for choosing a terminal from a Russian supplier may be the ease of upgrading the scanning module (if a particular TSD model provides such an option), repair, or reflashing - due to the availability of spare parts and, possibly, a wider geographical coverage of the service center area.

How to choose software for it

Selecting a data collection terminal as a hardware solution is half the battle. Its practical application, as we already know, involves the transfer of “collected” data for subsequent processing to an external computing module - on which a special program is installed.

Such solutions are presented in an extremely wide range on the Russian market. An example of an inexpensive, universal, and at the same time functional option is the ATOL Mobile Logistics program (LINK). It allows for the integration of data collection terminals and popular commodity accounting platforms based on 1C line products.

This program involves the use of the terminal as an element of the commodity accounting infrastructure, which operates on the basis of an algorithm that is developed using the configurator. This algorithm is created in the program in question and then loaded into the terminal. At the same time, the TSD must have the required hardware and software characteristics- for compatibility with the program (a list of compatible data collection terminals is given).

Within the framework of the general scheme practical application The terminal is supposed to be pre-loaded into it with information on goods that are subject to accounting - in a warehouse or on the sales floor. Shipment orders are generated at the warehouse, and the program ensures that the corresponding orders are reflected in the TSD. The order includes the established list of information on the goods being shipped. Using a data collection terminal allows you to track the actual volume of shipped items - each of which is read by barcode, the volume shown in this list.

Video - working with the data collection terminal:

An employee who uses the terminal promptly receives data on detected discrepancies between the stated indicators and the actual ones, as well as instructions on the need to correct the discrepancies. Also, using the data collection terminal, an employee can make notes in a special register about detected damage to goods, defects, and indicate other relevant facts about the items being shipped.

Upon completion of shipment and upon collection of all necessary data on it using TSD, all information is loaded into the goods accounting system. With its help, various commodity accounting documents can subsequently be generated.

The procedure for using terminals on other types of TSD software is, in general, very similar to that which characterizes the use of the ATOL solution. Actually, this is due to the uniformity of tasks that characterize the use of TSD within the framework of typical accounting operations in a warehouse and in areas where goods are sold.

Thus, the main criteria for choosing software for data collection terminals will be - given the likely comparability of their basic functionality (which, one way or another, is aimed at integrating TSD and a commodity accounting interface - based on 1C or an alternative solution):

• compatibility of software and a specific TSD model (you need to request lists of such compatibility from a specific supplier - as an option, referring to an example of such a list from ATOL);
• compatibility of the algorithm for processing “collected” data, which is proposed by software developers for TSD, with those production operations in which the terminal is used.

And if such compatibility is not implemented by default in the selected (and suitable according to other criteria) software, then it is necessary to establish in advance the possible costs for the necessary modernization of the existing data “collection” infrastructure or commodity accounting infrastructure - it is possible that they will be lower than the additional costs for installation of alternative software.

Summary

From the point of view of basic functionality, a data collection terminal is essentially a very simple device. Its main purpose is to collect information on objects in respect of which certain production operations are carried out (for example, acceptance or shipment) and to ensure the necessary processing of this information (for example, in order to compare the actual volume of goods received or shipped with the data reflected in work order and other accounting documents).

In general, such data is collected by reading a barcode located on the accounting object. Thus, the main criterion for the quality of TSD operation can be called adaptability to reading such codes:

• accurately;
• promptly.

For these purposes, it is necessary to introduce terminals equipped with the required type of barcode scanners into production. In addition, the data collection terminal itself must be suitable for use in a specific environment (at a minimum, taking into account climatic conditions).

The data collected by the terminal must be transferred to an external computing module. For these purposes, wired or wired cables that are optimal for specific application conditions are used. wireless interfaces- with which the device must be equipped.

TSD can only be used to solve basic problems - and be single-task (both in essence and in terms of its technical capabilities). And it can be used as a multitasking device with an expanded set of functions - for example, as a communication tool in the interaction of enterprise employees.

The selection of a data collection terminal with certain characteristics can be made taking into account the software factor with which the TSD is supposed to be integrated. Compatibility is required between the “collected” data management algorithms provided by such software and the hardware-software interfaces on a specific terminal model.
