Quick search and positioning of goods: when it is necessary to search for a certain goods, enter the relevant goods information in the handset, and scan the goods within a certain range. When the goods are scanned, the intelligent warehouse management system will send a prompt to facilitate the quick search of the goods. Electromagnetic backscatter RFID system, backscatter modulation and radar technology provide the theoretical and application basis for the backscatter coupling mode of RFID. When an electromagnetic wave encounters a space target, part of its energy is absorbed by the target, and the other part is scattered to all directions with different intensities. In the scattered energy, a small part is reflected back to the transmitting antenna and received by the antenna (so the transmitting antenna is also the receiving antenna). After amplifying and processing the received signal, the relevant information of the target can be obtained. Ensure the accuracy and reliability of the input data, and directly use barcode scanning to register and count the goods in and out of the warehouse without manual recording; Help enterprises reduce the labor cost input of logistics warehousing system and obtain higher income.
When goods are purchased and received or finished products are warehoused in the RFID intelligent warehouse management system, electronic labels are made. The labels are written into the enterprise definition information such as the purchasing unit, specification and model, and pasted onto the goods to complete the initialization of goods information. At the same time, the pallet electronic label is installed on the pallet to identify a specific pallet information;
The RFID intelligent warehouse management system is used for warehousing. The forklift transports goods through the warehouse gate. The reader / writer installed at the warehouse gate automatically collects the RFID tag information on the goods and the electronic tag information on the pallet, and directly sends the information to the data center. The background realizes the binding of the goods information and the pallet, completes the warehousing scanning binding, realizes the automatic scanning and binding, and automatically completes the warehousing operation without manual intervention;
The forklift continues to transport the goods pallets to the idle shelves. The shelves are equipped with passive RFID tags. In the process of shelving, the forklift RFID reader will read the pallet tags and rack tags, and directly send the information to the data center. The background automatically completes the binding of pallet information and rack information, that is, to complete the shelving operation of all goods on the pallet and realize accurate shelf management.
At present, PDA products on the market are generally equipped with Android, windows mobile, Windows CE and other systems, of which Android system is the most. The traceability of production can be fully realized by recording the labor number, time, operation and quality inspection results. It can also avoid mistakes caused by handwritten and visual information in the production environment. Warehouse management, RFID system is used for intelligent warehouse cargo management, which effectively solves the information management of warehouse cargo. For large storage bases, the management center can know the location and storage of goods in real time, which is of great significance to improve storage efficiency, feed back product information and guide production. By zoning the physical space of the warehouse, each physical space is allocated with passive RFID tags to effectively locate the goods in the warehouse and quickly retrieve them.
When the RFID intelligent warehouse management system moves the warehouse, it can be directly initiated by the forklift client. The forklift directly removes the pallet that needs to be moved. When the forklift collection system reads the cargo pallet label information, the RFID intelligent warehouse management system automatically unbinds the pallet information with the previously bound rack information. When the forklift forks the goods to the new material rack to complete the shelving process, the forklift reads the RFID intelligent storage management system to read the new material rack information and upload it to the data center. The RFID intelligent storage management system completes the binding of the new material rack and updates the inventory in real time.
When the RFID intelligent warehouse management system leaves the warehouse, the forklift first removes the cargo pallet from the rack, the forklift reading system reads the pallet information, and directly sends it to the data center. The background system checks the outbound information, and completes the off rack operation if it is correct. The RFID intelligent warehouse management system automatically unbinds the pallet information and the rack information; If it is incorrect, give an early warning;
After the goods are removed from the shelf successfully, the forklift transports the goods through the warehouse gate, and the reader / writer installed at the warehouse gate automatically collects the RFID tags and pallet tags on the goods, and directly sends the information to the data center. The background data center of the RFID intelligent warehouse management system completes the verification of the cargo tags and pallet tags. If it is correct, it completes the outbound operation, and the RFID intelligent warehouse management system automatically updates the inventory, If it is incorrect, an early warning will be given.
When the goods are stored in each link of the warehouse, the relevant information is automatically collected and recorded. The effective management of the goods packaging operation reduces the loss. The record of product quality in each production process, the rapid replacement of electronic labels, and the simple and rapid realization of products. In RFID backscatter coupling mode, the frequency of electromagnetic wave reflected by a target is determined by the reflection cross section. The size of the reflection cross section is related to a series of parameters, such as the size, shape and material of the target, the wavelength and polarization direction of the electromagnetic wave, etc. Since the reflection performance of the target usually increases with the increase of frequency, the RFID backscatter coupling mode adopts UHF and UHF, and the distance between the transponder and the reader is greater than 1m. RFID Reader/writer, transponder (electronic tag) and antenna constitute a transceiver communication system. However, for most small and medium-sized warehouses, PDAs with complete functions and easy operation are generally preferred. There are obvious differences between the two.
