the method comprises the following steps: the environment monitoring module detects and analyzes air environments inside and outside the automobile, the internal measurement unit detects and analyzes the air environments inside the automobile, the external measurement unit detects and analyzes the air environments outside the automobile, and the internal measurement unit and the external measurement unit send detection results to the processor;

step two: the processor sends the detection results of the internal measurement unit and the external measurement unit to the mode switching module, and the mode switching module switches the circulation mode of the air conditioner according to the detection results of the internal measurement unit and the external measurement unit;

step three: the air conditioner detection module detects and analyzes the running state of the automobile air conditioner through the output data, the heat dissipation data and the noise data of the air conditioner, obtains a running coefficient of the air conditioner through analyzing and calculating the output data, the heat dissipation data and the noise data of the air conditioner, compares the running coefficient of the air conditioner with a running coefficient threshold value, and sends a working abnormal signal to the processor when the running state of the air conditioner does not meet the use requirement;

step four: the processor receives the working abnormal signal and then sends the working abnormal signal to the maintenance recommending module, the maintenance recommending module receives the working abnormal signal and then analyzes and recommends a maintenance worker according to the current position of the automobile, the recommended coefficient of the maintenance worker is obtained by analyzing and calculating the distance between the maintenance worker and the current position of the automobile, the sum of the poor comments and the complaint times received by the maintenance worker within half a year and the working age limit of the maintenance worker, and the recommended maintenance worker is screened from the first three maintenance workers with the largest recommended coefficient.
