Temperature Alarm Model of Fresh Grapes in Refrigerated Carriage

摘要

Traditional monitoring of refrigerated compartments only monitors temperature and humidity in real time. When the temperature exceeds the critical range, the system sends out alarm information. This method has no function of predicting the temperature of refrigerated compartments environment. This paper mainly studies the early warning method based on statistical process control theory to ensure the safety of fresh grapes in the cold chain transportation process, and the paper set a concern mode between the normal mode and the alarm mode, and the alarm information is pre-judged to improve the accuracy of alarm, which provides a reference for the environmental safety of refrigerated vehicles.
