Train compartment air adjustment and control method and apparatus, storage medium, and program product

A train compartment air adjustment and control method, wherein comprising the following steps:

• 1) detecting PM2.5 concentration, PM10 concentration, CO concentration, NO2 concentration, SO2 concentration, O3 concentration, and the total number of bacterial colonies at an air supply port, an air exhaust port and a seat of a train;
• 2) establishing, according to the PM2.5 concentration, PM10 concentration, CO concentration, NO2 concentration, SO2 concentration, O3 concentration, and the total number of bacterial colonies at each detection point in a compartment, a mapping relationship between the total number of bacterial colonies D and the concentration of air pollutants d in each micro environmental unit, wherein the micro environmental unit is the detection point;
• 3) selecting a measured air pollutant concentration data set with a time length of N minutes, calculating the total number of bacterial colonies according to the mapping relationship, denoting a time series of the total number of bacterial colonies at the ith seat as XNi, denoting a time series of the total number of bacterial colonies at the jth air supply port or air exhaust port as YNj, performing hypothesis test by using Granger causality test to determine whether there is causality between XNi and YNj, and then obtaining a test result set of each seat detection point, m air supply ports and n air exhaust ports;
• 4) obtaining a nonlinear description model base of all seat detection points according to the mapping relationship and the test result set;
• and
• 5) inputting ventilation rates of all air supply ports and all air exhaust ports of the train to a grey wolf optimizer, calculating fitting results of the total number of bacterial colonies at the air supply ports/air exhaust ports under different ventilation rates, inputting the fitting results to the nonlinear description model base to obtain a fitting result of the total number of bacterial colonies at each seat, and determining the ventilation rates of all the air supply ports and all the air exhaust ports by using the fitting result of the total number of bacterial colonies at each seat.
