and determining the control action of the air conditioning system according to the first contrast relation.
Referring to fig. 1, in the present invention, a preset interval is divided into four intervals according to the size of a temperature parameter, which are [ T1, T2 ], [ T2, T3 ], [ T3, T4 ], [ T4, T5 ], where T1 is a first preset temperature, T2 is a second preset temperature, T3 is a third preset temperature, and T4 is a fourth preset temperature, each interval corresponds to a control action, and the four intervals correspond to four different actions, and it only needs to determine a corresponding execution action according to the size of the temperature parameter. The target parameter for controlling action adjustment is determined according to the temperature change value and/or the humidity difference, so that the humidity is stabilized while the temperature is controlled, and the comfort level of a user is improved.
Specifically, the four control actions are respectively quick temperature rise and humidity stabilization control, slow temperature rise and humidity control, slow temperature fall and humidity control and quick temperature fall and humidity stabilization control, the first contrast relationship is shown in fig. 1, four temperature intervals correspond to one control action, and when the temperature parameters are in the interval [ T1, T2 ], the quick temperature rise and humidity stabilization control is adopted; when the temperature parameter is in the interval [ T2, T3 ], adopting slow temperature rise and humidity control; when the temperature parameter is in the interval [ T3T4 ], slow cooling and humidity control are adopted; and when the temperature parameter is in the interval [ T4T5 ], adopting rapid cooling and humidity stabilization control. After the temperature parameters are detected, the corresponding control actions can be determined only by determining the temperature parameter interval where the temperature parameters are located.
Further, after determining the corresponding control action, it is further required to determine a specific target parameter for control, specifically, the environmental parameter detected in the present invention includes a temperature parameter and a humidity parameter, and when determining the target parameter for control action, it is required to determine according to both the temperature parameter and the humidity parameter, and it calculates a temperature variation value between two detected temperature parameters and/or a humidity difference between the humidity parameter in the environmental parameter and a set humidity value to determine the target parameter for control action, including:
