The RFID tag metal system utilizes the principle of radar reflection. The reader sends a microwave inquiry signal to the electronic tag through the antenna. The RFID tag metal is activated by the microwave energy of the reader, and after receiving the microwave signal, it responds and sends an echo signal with the tag data information. . The basic feature of radio frequency identification technology is to use radio technology to identify stationary or moving objects, to determine the identity of the object to be identified, en om funksie -inligting te onttrek (of identifikasie -inligting) van die voorwerp wat geïdentifiseer moet word.
The feature information of the object to be identified collected by the radio frequency identification system is usually processed by the intermediate software, or the collected identification information is directly passed through computer information processing technology (such as database technology) and computer network technology (Intranet & Internet) Technology) to achieve information integration, sharing, long-distance transmission, ens. directly to the relevant business application systems (such as: personeel bestuur, access control systems, goedere / assets tracking, pakhuise / logistieke bestuur, ens.). RFIDHY focuses on RFIDHY UHF RFID modules, UHF RFID readers and supporting RFID antennas, RFID-etikette, and can be implemented with system integrators to complete RFID projects. Our products have been reflected in the perfect performance of RFID jewelry management, RFID clothing supply chain management, RFID book archive management and other projects.
Based on UHF RFID, the material information is written into the RFID tag metal, and then the electronic tag is recognized by the reader, and the information of the material in and out of the library is accurately and reliably collected in real time; op dieselfde tyd, each storage device is installed. The electronic label is used to identify and facilitate the management and search of the storage location; realize the automatic storage allocation of materials into the warehouse, and carry out intelligent monitoring and visual management of the material in and out of the warehouse, improve the operation and management efficiency of the warehouse; and quickly and accurately carry out the RFID technology. Warehouse inventory work.

Management and information management level.
3. System design
3.1 Design ideas
Products or other goods that are off-line of the production line are installed with matching RFID cargo labels and cargo labels to record the goods according to the characteristics of the items before storage. After the goods label is installed, it will be placed according to the rules and waiting for storage;
The RFID channel type reading device is installed at the storage port, and the batch label information of the goods is read and uploaded to the background management system when the storage is completed, and the bulk storage of the goods is completed;
After the goods enter the warehouse, they will be sorted according to the specifications, put into the storage area of the corresponding kind, and an identification card will be installed for each storage place, and each identification card will be labeled with an electronic label, which will be used as the location label. And each identification card number is stored, the ID number in the location label is stored to identify the shelf number, and the ID number of the label is read by the staff holding the RFID handset, and the background system database can be called to obtain the storage information and information therein. Insluitend: the type, name, model, unit, unit price, production date, shelf life, performance, ens. of the item;
During the transfer operation, the staff holds the handheld RFID handset, and the system sends the transfer instruction to the mobile data collector. The transfer personnel finds the specified location, takes the specified quantity of goods from the location, and transports the goods to the warehouse. The destination location, the goods are sent to the location, the contents of the shelf label are modified, and the transfer operation information is sent back to the background system.
When the warehouse management operation is performed, the label number is read to determine whether the current job location is correct. Daarbenewens, as long as the ID number of a certain shelf is input, the related information of the ID can be retrieved from the background database, thereby realizing the material storage function.
The goods out of the warehouse and the warehousing are the same process. The same is the door to the warehousing. The RFID reading device can be reused. The RFID reading device scans all the cargo information of the library, and uploads the cargo information to the background system in real time. Outbound operation of the goods.
3.2 System framework
The RFID-based warehouse management system introduces RFID technology into the existing warehouse management, and automatically collects data for each operation link such as warehouse inbound, uitgaande, shifting, and inventory counting to ensure data in all aspects of warehouse management. The speed and accuracy of the input ensure that the company can accurately grasp the real data of the inventory in a timely and accurate manner and reasonably maintain and control the enterprise inventory.
3.3 Operation process
3.3.1 Label Initialization
The link is to initialize the card for the goods label and the location label, encode the goods label and the location label according to the enterprise material coding rules, and use the RFID label printer to write the encoded information into the electronic label, and if the information needs to be printed, Op dieselfde tyd, data such as library coded text or bar code information can be printed on the label.
Once the label is encoded and written, follow the label installation instructions to install the label on the goods and locations.
3.3.2 Outbound and inbound
After the goods are loaded with the goods label, they will be put into the warehouse through the storage port. An RFID reading device is deployed at the storage port to read the cargo label.
The RFID reading device will read the label information on all the goods in the warehouse in batches, and upload the label information to the background system, and the background system will complete the storage operation of the goods corresponding to the label information.
After entering the warehouse, the RFID handset will be used to complete the binding of the cargo information and the storage position information. After the warehouse personnel put the goods on the cargo space, they read the cargo space label and the cargo label, complete the binding of the two, and upload the binding information to the background, and the entire warehousing process is completed.
The outbound warehouse is the reverse operation process. The goods are cleaned out from the cargo space and executed out of the warehouse. When the RFID reading device is accessed through the outlet, the label information of all the goods will be read and the information will be uploaded to the background. The management system, the background management system will perform the check of the information and the outbound order information, and the correct upgrade will be able to exit the warehouse normally and complete the outbound process of the goods.
3.3.3 Transfer library
When the delivery of a batch of goods is nearing completion, when there is not much stock, or when the next batch of bulk goods storage notice is received, it is necessary to transfer the warehouse and free up the storage space for new goods. At this time, the transfer operation is performed using the RFID handset.
The RFID handset step is to read the location label of the location of the goods that need to be transferred, and then transfer the goods to the target location, and then use the RFID handset to read the location label of the new location, and the background system automatically performs the new label. The location information is updated to complete the transfer operation.
3.3.4. Inventory
The warehouse inventory is a periodic warehouse acquisition and inventory work in accordance with the conventional requirements, so as to timely grasp the current status of the inventory goods. During the inventory, the system downloads the inventory task to the RFID handset. The library administrator uses the handset to the task given warehouse and reads all the location tags in the warehouse to complete the inventory of the goods in the warehouse.
4. Equipment selection
The modern warehouse management system based on RFID technology will save labor to manually collect data costs, automate warehouse management operations, improve work efficiency, and reduce management costs by optimizing and optimizing important processes such as inbound, uitgaande, and inventory in the warehouse. Human error, more control, verkope, storage control, so that it can respond to production and sales needs more quickly, increase the core competitiveness of enterprises, and improve corporate performance.
