Cold chain transmission monitoring system based on RFID

Abstract

The invention provides a cold chain transmission monitoring system based on an RFID. The cold chain transmission monitoring system comprises a vehicle-mounted terminal device, a communication networkand a monitoring center, wherein the vehicle-mounted terminal device is installed in a compartment of a cold chain transmission vehicle and performs wireless data transmission with the monitoring center through a communication network, the vehicle-mounted terminal device comprises an RFID data acquisition unit, a central processor unit, a GPS positioning unit, a wireless communication unit, a display unit and an alarm unit. The cold chain transmission monitoring system adopts an advanced RFID technology, a GPS positioning technology, a communication technology and a temperature and humidity sensing technology, it is achieved that cargo temperature and humidity changes are recorded on an 'RFID label with a temperature and humidity sensor' in the cold chain transmission process and are uploaded to a monitoring center in real time, timely and accurate temperature and humidity monitoring is provided, accordingly cargo in-transit transmission parameters are mastered, and early warning can be triggered in time in necessity.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an RFID-based cold chain transportation monitoring system. Background technique [0002] Cold chain transportation refers to the transportation in which the transported goods are always kept at a certain temperature in the whole process of transportation, whether it is loading and unloading, changing the transportation mode, changing the packaging equipment, etc. The cold chain transportation mode can be road transportation, water transportation, railway transportation, air transportation, or it can be a comprehensive transportation mode composed of various transportation modes. Cold chain transportation is an important part of cold chain logistics. The objects of cold chain transportation mainly include: pharmaceuticals such as vaccines, blood products, etc., fresh food such as quick-frozen food, meat, cold drinks, vegetables, fruits, aquatic products, etc. [0...

AI Technical Summary

Problems solved by technology

Traditional temperature and humidity detection recorders are expensive and bulky, unable to measure the temperature of a single box, unable to automatically identify product information, and require wired connections and manual intervention to export data. Companies and customers cannot dynamically detect cold chain transport vehicles. The process state reduces the accuracy and real-time monitoring of the monitoring center, and cannot meet the requirements of temperature and humidity monitoring in the modern cold chain transportation industry
