The application of RFID in my country is in its infancy. It is mainly used for product anti-counterfeiting and identity recognition. For example, the second-generation ID card adopts RFID technology; Hong Kong International Airport also adopts a brand-new RFID system to check passengers’ luggage. track. But this kind of application is limited to a small area and has no impact on the entire production enterprise. However, the use of UHF RFID electronic tags in large-scale logistics and transportation is still a blank.
Comparative analysis of traditional business and information system
Traditional identification techniques and methods represented by barcodes have many limitations: information identification is static; information identification is contact-type; information capacity is limited; each storage and transportation unit cannot be uniquely identified; data storage and calculation It is concentrated and so on. Although the two-dimensional bar code solves the problem of information identification capacity, the bar code can only be applied to the circulation field (business flow and logistics information management), and cannot transparently track and run through the supply chain process. As we all know, when recognizing a bar code, the scanner must be aligned with the bar code, and the bar code can only be read at a time. For the company’s production warehouses that have a large number of incoming and outgoing goods every day, this workload is huge, and it also limits the further improvement of efficiency to a certain extent.
Compared with other automatic identification technologies, the RFID identification system has the characteristics of no contact, high degree of automation, durability and reliability, fast identification speed, adapt to various working environments, high speed and simultaneous identification of multiple tags, etc., and it is more extensive than other identification technologies. Uses, such as supply chain management, access control security systems, logistics systems, cargo tracking systems, electronic payments, production line automation, item monitoring, car monitoring, etc. Therefore, compared with barcodes, RFID has great technical advantages. It is predicted that RFID will be the most widely used automatic identification technology.
Refined management of data flow
In the traditional production and circulation links, documents are an indispensable part. In today’s large-scale production environment, a large number of document processing will not only reduce efficiency and increase labor costs, but also often cause various errors due to human factors. . The use of the RFID system can convert the “document flow” into a “data flow”, and use electronic means to transmit information to various links and departments, which is not only fast, but also has an error rate of almost zero. Its implementation is very simple, just add an electronic tag with an RFID chip on the product, and set up a dedicated read/write device in a specific place.
If RFID label printing device is used, wireless detection device is used to count the quantity of product in and out management; the storage location management function of finished product can be established and refined to improve the warehouse turnover rate and ensure the accuracy of inventory; it is coordinated with the delivery to ensure the product The optimal inflow, storage and outflow of the product; improve the accuracy of shipment, reduce labor intensity and workload; provide auxiliary data support for production planning and job scheduling management; at the same time, significantly improve the accuracy of product customer traceability. Through the implementation of ERP-based RFID solutions, the integration of RFID identification products and ERP for inventory and sales management is realized, which not only realizes the refined management of products based on RFID tags, but also conducts product inventory status and sales flow through ERP data flow Complete management.
Analysis of warehouse using RFID process
1) Warehousing: Items with RFID electronic tags on the outer packaging enter the warehouse, and the identification system at the entrance will record the warehousing information of the goods in the database.
2) The goods on the warehouse racks are all equipped with RFID tags, which is convenient for accurately and quickly finding the target when shipping.
3) Management of loading, unloading, inventory, receiving and dispatching of goods through forklift RFID or handheld RFID terminal.
4) Delivery: The RFID identification system at the exit of the warehouse will automatically read the target information and generate a delivery list.
The application of RFID technology not only meets the requirements of enterprise production and warehouse management, but also improves the accuracy and systemicity of management to a higher level, that is, an independent development model that takes the enterprise as the main body and combines politics, production, learning, research, and use. . Therefore, the application of RFID technology in manufacturing enterprises should be increased, and breakthroughs should be made in the fields of RFID common foundation and forward-looking, industrialization key technology and application key technology.
