RFID electronic tag for monitoring environmental data of cold chain logistics

Abstract

The invention relates to a radio frequency identification (RFID) electronic tag for monitoring environmental data of cold chain logistics. The tag comprises a tag body, and an RFID module, an environmental data monitoring module, an antenna module, a storage module and a central processing unit which are arranged on the body, wherein the RFID module, the environmental data monitoring module, the antenna module and the storage module are connected with the central processing unit. Compared with the prior art, the tag can reliably acquire temperature data, humidity data, photosensitive data, pressure data and the like in the production, transportation and sales processes in the cold chain industry in real time; and the cold chain logistics is applied to primary agricultural products such as vegetables and fruits, meat, poultry and eggs, aquatic products and flower products, processed food such as quick-frozen food, packaged cooked food of the poultry, the meat, the aquatic products and the like, milk, ice cream and dairy products, and fast food raw materials, special commodities such as medicines, vaccines, blood products and other biological products, and special dangerous chemicals, wines and cigars, semiconductor packaging and the like.

Description

technical field [0001] The invention relates to an RFID electronic tag, in particular to an RFID electronic tag used for monitoring cold chain logistics environment data. Background technique [0002] The so-called cold chain logistics generally refers to a systematic project in which temperature-sensitive products are always kept in a specified low-temperature environment in all links of production, storage, transportation, sales, and consumption to ensure the quality of items and reduce logistics losses. It is established with the development of logistics technology and refrigeration technology, and is a low-temperature logistics process based on refrigeration technology and refrigeration technology. The cold chain consists of four aspects: frozen processing, frozen storage, refrigerated transportation and distribution, and frozen sales. [0003] The scope of application of cold chain logistics includes: primary agricultural products: vegetables, fruits; meat, poultry, eg...

AI Technical Summary

Problems solved by technology

[0004] The general RFID tag only sends out the unique ID number. However, the purpose of cold chain logistics is to ensure the quality of refrigerated and frozen goods. In cold chain logistics transportation, we not only need to know the unique ID number of the tag, but also need to know it in real time. Understand the data and changes of temperature, humidity, light sensitivity and pressure in the surrounding environment of the tag, but the current RFID electronic tags cannot meet the above requirements
