Food is the heaven for the people.” Food occupies a very important position in people’s lives. The agricultural product supply chain includes production, packaging, processing, distribution, sales and other links. It is a long and complex supply chain. In circulation The problems that arise in the process are often difficult to monitor, and it is impossible to accurately and quickly find the root cause and take effective measures in time. Therefore, in order to ensure the quality and safety of agricultural products, it is important to monitor and trace the entire process of agricultural products. significance.
The use of RFID technology in combination with networks and information systems for data collection and communication aims to improve the efficiency of information collection and transmission, effectively identify agricultural products, and integrate scattered information to meet the traceability requirements.
In the production stage, the producer stores the product name, variety, origin, batch, pesticide application, producer information and other necessary content in the RFID tag, and uses the RFID tag to record the initial product information and production process; in When products are purchased, the content of the label is used to quickly sort the products, and different purchase prices are given according to the different conditions of the products.
In the processing stage, products are sorted using the information in the RFID tags, and only products that meet the processing conditions can be allowed to enter the next processing link. For products that enter the processing link, use the information recorded in the RFID tags to deal with different products in a targeted manner to ensure product quality; after the processing is completed, the processor will provide the processor information, processing method, processing date, and product The grade, shelf life, storage conditions, etc. are added to the RFID tag.
In the transportation and storage stage, RFID tags and fixed readers installed along the way are used to track the route and time of the transportation vehicles. Install fixed readers at the import and export of the warehouse to automatically record the entry and exit of the product. Many agricultural products have higher requirements for storage conditions, storage and payment. Use the information recorded in the RFID tag to quickly determine whether the product is suitable for storage in a warehouse and how long it can be stored; when leaving the warehouse, choose the priority to be released according to the storage time The products can avoid economic losses; at the same time, the use of RFID can also realize the rapid inventory of the warehouse, helping managers to know the status of the products in the warehouse at any time.
In the sales stage, merchants use RFID tags to understand the status of purchased products and help merchants implement access management for products. When collecting money, using RFID tags can confirm the price of a customer’s purchase of goods more quickly than using a barcode, and reduce the waiting time for customers. Merchants can write the name of the mall, sales time, sales personnel and other information into the RFID tag, and confirm the product when the customer returns and recalls the product.
When there is a problem with the product, because the information of the product’s production, processing, transportation, storage, sales and other links is stored in the RFID tag, the entire process can be traced according to the content of the RFID tag, helping to determine the problematic link and the scope of the problem product . Use the reader to quickly find the unsold problem products in the warehouse, and consumers can also use RFID technology to confirm whether the purchased product is the problem product and whether it is within the scope of the recall.
In addition, while adding information to the RFID tag, the information is transmitted to the public database through the network. Ordinary consumers or units purchasing products can effectively help by comparing the content of the RFID tag of the product with the records in the database. Identify counterfeit products.
