Aiming at current status of lack of cold-chain logistics online monitoring system

a real-time monitoring system for the cold-chain logistics based on GPRS technology is designed.In this system

a RX62N microcontroller is used as processing core

GPRS technology

GPS technology

temperature measuring technology and 2.4 GHz wireless communication technology are integrated in this system.The inside temperature and the location of the refrigerator car are collected by the vehicle terminal

and transmitted to the background monitoring server through the GPRS net

so that the inside temperature and the running track can be monitored.Through testing

this system can get current temperature and location accurately

record and alarm the exception of refrigerator car

which meet the application requirements of cold-chain logistics companies.
