RFID realizes the informationization and timeliness of warehouse management
It is conceivable that the importance of warehouses is the most important aspect of enterprise management, how to make warehouses be used efficiently. The rent of the site is becoming more and more expensive, and the turnover speed of goods in the warehouse needs to be continuously accelerated to increase the frequency of use of the warehouse. Therefore, warehouses with the same area have to become taller (shelf) faster (turnover) and stronger (management), so modern warehouse inventory management is constantly upgrading and optimizing. In the management of modern warehouses, the efficiency of entering and leaving warehouses will directly have a huge impact on the economic benefits of the warehouse. The scientific and effective warehouse location management, entry and exit, and inventory inventory will be realized through RFID technology to realize the informationization and timeliness of warehouse management Change.
RFID technology realizes superior functions such as non-contact, repeated use, fast scanning, and large data capacity. More and more warehouse management uses RFID technology to maximize the benefits of warehouse management and the core of the enterprise on the basis of information and digitization. Competitiveness.
The warehouse management system design uses the following three-tier architecture:
Information collection layer: by issuing RFID electronic tags, new goods are equipped with RFID electronic tags. The unique ID number of the tag or the code written by the user can identify the goods. The reader can automatically collect the label information, so as to realize the information collection function of the goods.
Data transmission layer: The cargo tag information collected by the RFID reader can be transmitted to the background system for analysis through the relevant communication interface. The transmission communication interface can be selected according to user needs. RS-485, RS-232, and Ethernet can be selected. Internet, WIFI, 4G or GPRS, etc.
Goods management: PC terminal or back-end data center receives the data from the reader and analyzes the data to determine the process of goods out of storage, storage, relocation, inventory, etc. At the same time, it generates corresponding reports and detailed orders. Do the corresponding processing in the system.
RFID warehouse management system hardware is mainly composed of RFID electronic tags, fixed readers, handheld readers, servers, personal computers, etc., and realizes mutual connection and data exchange through the network.
The RFID warehouse management system software is composed of a supply chain management system, an RFID tag issuance system, and an RFID tag identification and acquisition system. These systems are connected to each other to complete the various processes of item management. The background database management system is the core of the entire system, and RFID identification and collection is the basis and means to realize the management function.
RFID warehousing logistics management system is composed of card issuance labeling, outbound management, inbound management, allocation and shifting, inventory counting and additional functions. The outbound management system includes outbound cargo application, outbound cargo identification, and outbound record download. The storage management system includes storage location allocation settings, unloading goods identification, and storage record management.
RFID technology warehouse management workflow:
Carry out card writing and labeling for RFID electronic tags: labeling newly purchased goods to be equipped with RFID electronic tags. The unique ID number of the RFID electronic tag or the data written by the user can be used as the identification code of the goods. The data is used to record the name of the goods, the time of purchase, the warehouse to which it belongs, and the attributes of the goods. When the reader installed in each channel recognizes the RFID electronic tag, it can automatically obtain all the information of the goods.
Warehousing: First, arrange the storage location on the system for the goods that need to be warehousing, such as the type of goods, which warehouse and which shelf need to be placed; Secondly, place all the items with RFID electronic tags in the area to be warehoused, Shipped into the warehouse from the entrance channel; when passing through the channel, the RFID reader will automatically identify the tag information, if the tag information and quantity recognized by the reader are correct, then enter the warehouse, if the tag information recognized by the reader is wrong or the number is small , The system will prompt; when entering the warehouse, the operator can accurately store the goods to the corresponding warehouse area according to the label information and system prompts. At the same time, the system will automatically follow the item information (date, material, category, quantity, etc.) and form List of receipts.
Outbound: To apply for goods out of the warehouse, fill in the application form for the items that need to be out of the warehouse on the personal computer. After receiving the outbound order, the warehouse management personnel find out the corresponding items through the handheld or query the server, and place the goods in the area to be out of the warehouse. The goods with RFID electronic tags to be out of the warehouse are recognized by the RFID reader device through the entry and exit channels before loading. The outgoing channel reader / writer device checks the identified RFID electronic label information with the outbound application form to confirm whether the loaded goods are consistent, and if they are inconsistent, repeatedly identify or supplement the out of stock. The system automatically updates the item information (date, material, category, quantity, etc.), and forms the details of the warehouse receipt.
Transfer and storage: The goods to be transferred and transferred to the warehouse will be recognized by the RFID reader installed next to the passage when entering and exiting the channel. The RFID reader records the current tag information and sends it to the background center. The background center judges whether it is warehousing, warehousing or transfer based on the order of the RFID electronic tags identified by the entry and exit channels. You can also use the RFID handheld to shift the goods. When the warehouse administrator finds that a certain goods is misplaced, you can manually place the goods. At the same time, you can change the RFID electronic tag information and send it to the server to achieve quick and convenient movement. Bit function.
Inventory check: Account check: Obtain the information in the RFID tag of the cargo location through the RFID handheld machine, and check the information with the information in the warehouse management system. The management personnel only need to walk through the cargo space with the RFID handheld machine. Complete the inventory.
Account verification: by checking the RFID electronic label information of specific goods and the information points stored in the warehouse management system, each physical object verification is performed to ensure the authenticity of the RFID electronic label and the object.
The RFID warehouse management application utilizes advanced RFID technology, combined with wireless LAN, database and other technologies to perfectly integrate the entire warehouse management with RFID radio frequency identification technology, which can efficiently complete various business operations, improve warehouse management, and increase efficiency and value.
