Design of Cold Chain Logistics Information Real Time Tracking System Based on Wireless RFID Technology

In order to improve the proportion of cold chain distribution, effectively control transportation links and information, and ensure the quality of cold chain food, it is necessary to establish an effective monitoring and tracking mechanism in all aspects of cold chain transportation. Therefore, a real-time tracking system of cold chain logistics information based on wireless RFID technology is proposed. The tag data sensing terminal, reader data transfer terminal and background server data management terminal are used to construct the real-time tracking system framework of cold chain logistics information, and the wireless RFID card reader is used to obtain the real-time temperature of food, vehicle running position information, agricultural product information and other data, so as to realize the real-time tracking and monitoring of cold chain logistics information. The experimental test shows that the function of the system meets the needs of real-time tracking of cold chain logistics information, achieves the system design goal, and ensures the quality of cold chain food.
