[0076]

[0077] Among them, rs zl is the total number of standing passengers in the carriage.

[0078] Specifically, "carriage" refers to a single car of a train. Taking the high-speed rail as an example, assuming that the high-speed rail displays the location information as "car 05, number 12F", the corresponding car 05 is represented as the car number, that is, the car refers to the entire car of car 05; the set value of the car temperature, the calculated value of the car temperature, and the ideal value of the car temperature are all in degrees Celsius, and the ideal value of the car temperature is set by technical personnel in this field according to the external ambient temperature and passenger comfort requirements, and the range of the ideal value of the car temperature is between 20°C and 26°C; the set value of the average speed of the train and the ideal value of the average speed of the train are both in kilometers per hour, and the ideal value of the average speed of the train is set by technical personnel in this field according to the nature of the train. The set value of the average speed of the train is set by technical personnel in this field according to the form, path, and outdoor environment of the train. Due to the complexity of the road type and the impossibility of environmental factors, the set value of the average speed of the train is inconsistent with the ideal value of the average speed of the train; when the train speed increases, more air will flow through the body of the train during the train travel, and the flow The air can take away the heat in the car, so the train speed is added as an influencing factor; because the density of passengers in the car will affect the temperature distribution and air flow, the car population density reference factor is added as an influencing factor; when the activity level of passengers in the car increases, the temperature needs to be lowered to reduce excessive heat sensation, so the car population activity reference factor is added as an influencing factor; in order to avoid the error of missed detection in the video, different operating periods of the train have different requirements for temperature, so a holiday reference factor is added as compensation for the temperature influencing factor. The following matters need to be noted when calculating the holiday reference factor: "Special time period" refers to national holidays, the day before holidays, and weekends (non-make-up time). For example, April 4 (Thursday) to April 6 (Saturday) in 2024 belong to the Qingming Festival holiday. Assuming that the train travel time is April 3, 2024, it belongs to the special time period. Assuming that the train travel time is April 7 (Sunday), 2024, although it belongs to the weekend, it belongs to the make-up time, which corresponds to the non-special time period.

[0079] The above units are only examples, and those skilled in the art may set different speed units according to actual needs when implementing this solution.

[0080] This embodiment solves the problem of low practicality of the traditional dual-purpose cooling and cooling system through the control module. The control module calculates the set value of the vehicle compartment temperature, and the refrigeration module and the heating module implement cooling or heating according to the set value of the vehicle compartment temperature, thereby improving the temperature comfort felt by the human body in the vehicle compartment. The temperature can be flexibly adjusted according to actual needs, and the appropriate temperature can reduce energy loss, meet environmental protection requirements, and improve practicality.

[0090] The communication module transmits information about whether the thermal insulation performance of the compartment is good or bad to the user end.

[0091] Specifically, the following steps are referred to when the cabin thermal insulation performance evaluation module evaluates: when the cabin thermal insulation performance factor is less than or equal to the selection threshold of the cabin thermal insulation performance factor, it indicates that the cabin has good thermal insulation performance; when the cabin thermal insulation performance factor is greater than the selection threshold of the cabin thermal insulation performance factor, it indicates that the cabin has poor thermal insulation performance; the selection threshold of the cabin thermal insulation performance factor is set by technical personnel in this field according to the material of the cabin wall, and the wind speed of the air outlet set in the cabin is adjusted according to the information of whether the cabin has good or bad thermal insulation performance. For example, when the cabin has good thermal insulation performance, the wind speed can be appropriately reduced to save energy; otherwise, the wind speed needs to be increased to maintain a comfortable environment.
