Brief Analysis of RFID Technology Improving the Efficiency of Warehouse Management
At present, RFID (Radio Frequency Identification) is widely used in warehouse logistics management systems. In particular, the application of the stereoscopic library in the tobacco factory shows the advantages of RFID technology to the fullest. RFID (Radio Frequency Identification) brings not only improvements in the information management model, but also the benefits of user care. Recently, as Chinese people pay more and more attention to food safety and hygiene, some large domestic food factories also hope to use RFID (radio frequency identification) technology in their raw material processing, production, storage and transportation to realize material traceability and improve production. effectiveness. Recently, as Chinese people pay more and more attention to food safety and hygiene, some large domestic food factories also hope to use RFID technology in their raw material processing, production, storage and transportation to realize material traceability and improve production efficiency. Turck China is a wholly-owned subsidiary of Turck Germany and has long been committed to the development of industrial control, covering everything from sensors, intermediate connectors to fieldbus IOs and controllers for almost all electrical control products. In 2005, Turck China introduced BLident products to China in a timely manner. BLident is a RFID product developed by Turck on the BL67/20 fieldbus platform. The BL67/20 fieldbus platform gives BLident products a great performance advantage: it supports multiple communication methods, and can easily exchange data with various controllers or industrial computers; any combination of 2~8 channels; IP67 or IP20 protection grade product; compatible with all products under BL67/20 platform, including digital and analog input/output modules, RS232/422/485 communication module, high-speed counting module, etc.; BLident supports dynamic reading and writing, carrier code The maximum allowable moving speed can reach 10m / s; and can provide a thin carrier and a high temperature carrier directly mounted on the metal surface. All of this makes BLident's automation control and information management applications in the industrial control field a good one. Turck offers the perfect RFID solution based on the customer's various process conditions. The food industry is an emerging industry that Turck is currently focusing on. As Chinese people pay more and more attention to food safety and hygiene, the processing, production, storage and transportation of food raw materials are required to be traceable, thus ensuring the safe and reliable processing of raw materials. In these processes, RFID has been fully applied. Especially in the raw material warehouse, the application of RFID makes the automation and informationization of the control system further improved, and the control scheme is more perfect. The project is a MSG production line invested by a large joint venture food company in China. It has the most advanced MSG production technology and technology in the country, so customers hope to use advanced technology, reliable performance and cost-effective products and systems in this project. In particular, a material traceability management system is established in the raw material transfer warehouse, and the materials are managed and traced in real time through the use of RFID technology. The system should automatically convert the inbound data sheet into the data information corresponding to a single tray, and automatically write it into the code body through the RFID read/write head. Then, the system automatically allocates the warehouse area, instructs the forklift to place the material in the corresponding position of the warehouse, and binds the position information to the tray uploading code body information in the system. When out of the warehouse, the system can automatically guide the forklift to extract materials from the warehouse on a first-in, first-out basis and send them to the corresponding production line according to the production tasks that the production orders are decomposed into. In the process of extracting the logistics, the head on the forklift should check the code carrier on the material pallet to determine whether the material is needed. If an error occurs when the material is in the warehouse, out of the warehouse, or enters the production line, the system should automatically alarm and prompt the operator to perform related processing. In addition, the pallet needs to be reused throughout the warehouse management process. The tray embedded in the code carrier is called a digital tray and is widely used in all current warehouse management systems using RFID technology. This type of pallet does not affect the loading of the goods, but also facilitates the precise digital management of large quantities of goods. Digital pallets are easier to access in the warehousing process than traditional barcoded pallets. Because it does not require workers to print a lot of barcodes in advance, then scan them with Barcode guns and attach them to each tray. Therefore, the working time is reduced and the work is reduced. In addition, the code carrier is suitable for harsh environments, even if the surface has scratches and stains, it will not affect normal reading. Moreover, it is not as easily destroyed by rain as a barcode and can be reused. The uniqueness of the code carrier UID also improves the accuracy of material traceability. In small warehouses, the use of RFID forklifts for material access is undoubtedly the best choice. Since the RFID read/write head is mounted on the front end of the forklift, which is closer to the code carrier on the tray, the reading effect is greatly improved. In addition, the RFID forklift tracks the pallet in real time, ensuring the reliability of the entire warehouse management system. Moreover, in the entire storage process, eliminating human intervention can reduce operational errors and improve work efficiency. Due to the scattered location of production equipment and raw materials, the on-site environment is humid, the materials are dusty, and the production is continuous, the types of materials are many, etc. We recommend customers to use BLID system based on fieldbus IP67 protection level. In addition, since the raw materials for production are food products, a standard carrier with a degree of protection of IP68 and suitable for the food processing industry is selected in this project. other AST Industry Co.,LTD , https://www.astsoundchip.com
