Description

technical field [0001] The invention relates to a label with the functions of temperature collection, processing and recording. In particular, the label includes two wireless communication interfaces: a passive ultra-high frequency radio frequency identification and an active 2.4GHz wireless interface. Background technique [0002] Cold chain logistics generally refers to a systematic project in which refrigerated and frozen foods are always kept in a specified low temperature environment in all links of production, storage, transportation, sales, and consumption to ensure food quality and reduce food loss. It was established with the advancement of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on refrigeration technology and using refrigeration technology as a means. [0003] In the process of cold chain logistics, it is necessary to use real-time temperature monitoring and early warning mechanisms to...
