Problems solved by technology

[0003] In a refrigerated vehicle, the air enters the refrigerated vehicle through the evaporator. If the speed of the compressor and fan of the refrigerating unit is improperly selected, the speed and temperature of the air flowing through the evaporator will not meet the requirements of the temperature distribution in the refrigerated vehicle, which will affect the temperature of the vehicle. The quality of internal biologics

Abstract

The invention discloses a refrigerated truck temperature control method and system based on big data analysis. The method includes the following steps that actually-measured data of the temperatures of monitoring points in a refrigerated truck, the temperatures of all monitoring points on the outer surface of the refrigerated truck, the environment temperature, the truck speed, the rotation speedof a compressor of a refrigerating unit and the rotation speed of a fan are obtained through tests; clustering analysis is conducted on the obtained data, and multiple clustering clusters are obtained; the multiple clustering clusters serve as training samples, the rotation speed of the compressor and the rotation speed of the fan serve as output variables, and an ellipsoid unit neural network istrained; and on the basis of the ellipsoid unit neural network, the rotation speed of the compressor and the rotation speed of the fan are controlled in real time. By the adoption of the method and system, quantified real-time control of the temperature of the refrigerated truck can be achieved and is more reasonable than traditional adjustment and control conducted according to experience.

Description

technical field [0001] The invention relates to the field of refrigeration control, in particular to a method and system for controlling the temperature of a refrigerated vehicle based on big data analysis. Background technique [0002] Biological preparations play a very important role in people's lives. Most biological preparations need to be refrigerated at low temperatures during circulation, and the cold chain logistics market for biological preparations is huge. With the improvement of people's requirements for medical security, the safety of biological agents that need to be refrigerated has encountered higher requirements and challenges. In recent years, the unqualified events of biological preparations have raised people's vigilance, and the cold chain logistics of biological preparations has been paid more and more attention. The refrigerated truck has the functions of heat preservation and refrigeration, which can meet the requirements of short-distance refrigera...
