A cold machine regulation method and system for cold chain logistics
The application discloses a cold machine regulation and control method and system for cold chain logistics, and relates to the technical field of cold machine regulation and control. The cold machine regulation and control method for cold chain logistics collects environment data, cargo state data and cold machine operation state data of a cold chain carriage; performs feature mining and evaluation processing on the cold machine operation state data, extracts a cold machine health evaluation value, and estimates a cold machine effective refrigerating capacity; performs classification analysis and fusion processing on the environment data and the cargo state data to obtain a heat load demand of the cold chain carriage; based on the cold machine effective refrigerating capacity and the heat load demand, a comprehensive cost function is constructed, and multi-objective dynamic optimization solving processing is performed to obtain a cold machine control sequence. The cold machine is regulated and controlled through the cold machine control sequence, so that the cold machine output is dynamically adapted to the actual demand of the carriage, the deterioration of goods caused by insufficient refrigerating capacity is effectively avoided, the preservation effect in the process of goods transportation is improved, and the control precision is improved.
