and step S103, if the non-running duration time of the elevator car reaches the set time of the stop countdown, closing the elevator air conditioner.
The running state of the elevator car can be detected by various methods, for example, detection signals such as door opening, light turning on or weighing are switched in to determine that the elevator car is in a starting running state or a stopping running state.
Specifically, the technical scheme provided by the embodiment is mainly characterized in that the running state of the elevator car is detected, when the situation that the elevator car does not run is detected, the stop countdown of the elevator air conditioner is started, the time for the elevator air conditioner to stop running can be obtained, whether the elevator air conditioner needs to be closed or not is judged according to the stop running duration of the elevator air conditioner and the set time of the stop countdown, and if the stop running duration of the elevator car reaches the set time of the stop countdown, the elevator air conditioner is closed.
The method controls the air conditioner to be closed through the set delay time of the machine halt countdown, avoids frequently operating the elevator air conditioner in the peak time period of the elevator operation, solves the problem of high power consumption of the elevator air conditioner, and realizes energy-saving control of the elevator air conditioner.

In one embodiment, the number of starting runs of the elevator car in each time period can be obtained by acquiring an accumulated value of the starting of the elevator. When the elevator is in a starting state, the elevator starting accumulated value of the time period in which the elevator car is started is updated, for example, the accumulated value is added by 1, and the starting running times of the elevator car in each time period can be obtained by obtaining the elevator starting accumulated value of the elevator car in each time period.
In one embodiment, after the starting operation times of the elevator car in each time period are obtained, the set time of the stopping countdown of the elevator air conditioner of the elevator car in the corresponding time period is further determined according to the starting operation times of the elevator car in each time period.

summing the shortest running time value and the shortest stopping time value of the elevator air conditioner to obtain the running period of the elevator air conditioner; setting an operation cycle of the elevator air conditioner to the time interval.
Since the compressor of an elevator air conditioner usually has a minimum down time requirement, i.e. when the compressor is out of operation, a minimum down time has to pass to allow the compressor to be restarted. The technical scheme of the embodiment is directed at the starting operation characteristics of the elevator air conditioner, and the operation cycle of the elevator air conditioner is specified to be a time interval, so that the operation cycle of the elevator is divided. Generally, an operation period of an air conditioner of an elevator requires a minimum of 7 minutes for starting up and a minimum of 3 minutes for stopping, and the operation period of the elevator can be divided into time intervals of 10 minutes. Taking the day of elevator operation as an example, with 10 minutes as a time interval, the day of elevator can be divided into 144 time periods.
