Design of 5G-Based remote intelligent control system for fresh-keeping environment of refrigerated trucks
In order to solve the complicated problem of environmental control design in refrigerated trucks and further improve the remote intelligent operation and maintenance level of refrigerated trucks,combined with the design of cold-storage refrigerated trucks,a remote intelligent control system of refrigerated truck fresh-keeping environment was developed.The control system architecture was established from the data layer,mechanism layer and physical layer,and the threshold database of environmental parameters was established based on the shelf life theory.The collaborative intelligent control scheme was formed by integrating neural network,fuzzy control and PID algorithm.Building a multi-terminal monitoring and control platform using 5G and PLC technology Through the static control performance test of refrigerated truck,the fastest temperature increase rate of the interior environment during the day is less than 0.4℃/h,and the temperature above the threshold is controlled within 0.5℃.The dynamic operation test of refrigerated truck indicates its excellent fresh-keeping effect of food goods.This study can provide reference for the fresh cold chain transportation industry to improve the transportation quality.
