The general function of the data collector
Data acquisition should have data acquisition, data transmission, data deletion and system management functions.
Data collection
(C20) and the quantity (N4) are stored in the data storage in the text data format in the data acquisition unit, by reading the barcode of the product through the scanning device and directly checking the quantity of the product or inputting it through the keyboard.
Data transmission
The data transfer function has data download and upload.
Data download is the need to confirm the data collector to the product information from the computer to the data collector, the data collector and the computer through the communication interface between the computer management system to run the corresponding function of the equipment provided by the manufacturer's data Transfer program, transfer content can include: commodity bar code, name and quantity. Data can be downloaded in the data collection, the current bar code to read the product name and the need to confirm the number.
Data is uploaded to the product data collected through the communication interface, the data will be sent to the computer, and then through the computer system, the data will be converted to the corresponding database.
Data deletion
Data in the data collector in the completion of the transmission to the computer system, you need to delete the data, otherwise it will lead to the re-read data superposition, resulting in data errors. In some cases, the data may be transferred to the computer several times, until the data validation is invalid before they can be deleted.
System Management
The system management function checks for disk space and system date and time adjustments.
Need to consider some of the details
Document No
In the process of the flow of goods, usually a single number to distinguish between different types and different batches of data, in the case of data download, the data collector may also store a number of documents of goods data, it is necessary By document number to be distinguished.
Data download
Data download for data collection provides a convenient, but in some cases, but will bring some trouble. For example, the data download takes time, encountered no prior registration of the bar code, adjust it is too much trouble. Generally used after the first data collection, in the computer system for processing.
Duplicate goods
In the process of data collection, you may encounter the same kind of goods repeated reading of the situation, there may have been read the wrong people repeat the product read again, there may be the same goods, as not in the same position caused Repeat the goods but not repeat the number of cases, which need to read a commodity when the display of the original number, if not read before, then zero. The quantity of the commodity is the sum of the original quantity of the commodity and the current input quantity.
And computer system functions
Data collection of the menu, you can add the system to complete the functions, such as: commodity library, the goods out of the library, replenishment of goods and commodity inventory. This data acquisition, the operating state clear, but the interface increased, and data collection data content and process is entirely consistent, generally do not use this approach. The purpose of the commodity data of data collection is to determine the data uploading of different functions of the computer system. Sometimes, the same batch of data is used as the inbound and outbound data to facilitate the operation and reduce the re-reading of the data .
Third, the application of data acquisition
As the bar code identification with fast, accurate, easy to operate, and other characteristics of the circulation of goods storage and distribution center into the library. Inventory, distribution and other management, as well as the management of commodity stores in the introduction of bar code, can make management work to save manpower. Reduce errors, improve work efficiency, and protect the smooth flow of goods.
Application of computer systems and handheld terminals can be combined easily and accurately to complete the flow of goods related to management.
Warehousing and distribution center applications
Acceptance of goods into the warehouse
According to the order contract (or order) to the order data to the handheld terminal, bar code products do not have the original packaging of goods ready internal bar code, goods to the internal bar code after the first bar code to the original bar code does not correspond to the product packaging, Scan a barcode of goods, the handheld terminal display can automatically display the number of goods that should arrive, after verification can be confirmed directly, or enter the actual number of the keyboard with the arrival. After the storage of goods in accordance with its classification and attributes to the corresponding cargo space, with a handheld terminal to scan the bar code to place the goods and then scan the location of the bar code on the shelves of all goods Arrangement after the arrival of the handheld terminal Into the cradle connected to the computer system, you can send the goods arrival and inventory location data to the computer.
Goods shipped out of the library
According to the replenishment application of each branch, the computer system makes the replenishment instruction book of each branch according to the quantity of the corresponding commodity in the store. After the goods to be replenished are concentrated, the handheld terminal storing the batch data is scanned, Bar code and confirm the number of goods out of the library, the completion of handheld terminal data will be transmitted to the computer system.
Inventory check
Using the handheld terminal in order to scan the goods on the warehouse shelf bar code, and enter the actual number of stocks, the operation will be completed after the actual number of stock delivered to the computer system, the computer system for processing, to make a variety of inventory profit and loss reports and analysis reports.
The Application of Commodity Marketplace
Commodity stores used to complete the replenishment of goods, arrival, sales, inventory and other processing, the original packaging is not universal commodity bar code products to be labeled home-made bar code.
Automatic replenishment of orders
Hand-held terminal for automatic replenishment processing. First of all goods on the shelves of goods bar code read, and then in accordance with the number of goods in the keyboard using the keyboard and then enter the number of replenishment; the data obtained through the cradle to send to the computer host.
