Food safety tracking system in cold chain logistics based on radio frequency identification device (RFID) and data validation method of system
The invention relates to the technical field of food transportation and storage safety, and provides a food safety tracking system in cold chain logistics based on a RFID. The system comprises constant space and an active RFID label. The active RFID label is arranged in cold insulation space, a plurality of articles are stored in the constant space, and each of the articles is provided with a passive RFID label. When attention parameters of the constant space are higher than preset upper limit values or lower than preset lower limit values, the active RFID label transmits attention parameter information to each of the passive RFID label which stores that attention parameter information. As control is achieved through a plurality of the passive RFID labels, the cost is saved. The invention further provides a data validation method of the system, and accordingly, data are safe.
