Design of Dynamic Monitoring System for Cold Chain Logistics Vehicles Based on Internet Digital Intelligence Technology

Aiming at the problems of low transportation efficiency, poor effect and low customer satisfaction in traditional offline fresh cold chain logistics, this paper designs a cold chain logistics vehicle dynamic monitoring system by using Internet digital intellectualization technology. Based on GPS positioning technology and GPRS wireless technology, the fresh logistics vehicle dynamic monitoring system is designed to optimize the VRPTW model. 200 fresh orders from a fresh distribution center were selected for example verification. The experimental results show that the average temperature and humidity error of this algorithm system is 0.098°C and 0.59RH less than that of a certain type of temperature and humidity measuring instrument respectively, and the satisfaction of fresh distribution customers is increased by 7%. It is found that the application of the cold chain logistics vehicle dynamic monitoring system based on the Internet digital intelligence technology can significantly improve the logistics distribution efficiency of enterprises and customer satisfaction.
