and S1, when the microcontroller determines that the button is pressed, sending an opening work instruction to the microcontroller of the ultrasonic transducer and/or sending an opening work instruction to a switch driver of the sterilizer.

And S2, the microcontroller records the starting time of the transducer and/or the sterilizer, and if the preset time (such as 2 seconds) is reached, the microcontroller sends a stop instruction to the transducer and/or the sterilizer, the transducer stops vibrating, and the sterilizer stops spraying disinfectant.

The embodiment of the application also provides another control method of the microcontroller, which comprises the following steps:

and S1, the microcontroller receives the monitoring information that the image processing equipment or the infrared sensor feeds back that no user exists in the elevator, and sends an operation starting instruction to the microcontroller of the ultrasonic transducer and/or sends an operation starting instruction to the switch driver of the sterilizer.

And S2, the microcontroller records the starting time of the transducer and/or the sterilizer, and if the preset time (such as 5 minutes) is reached, the microcontroller sends a stop instruction to the transducer and/or the sterilizer, the transducer stops vibrating, and the sterilizer stops spraying disinfectant. The microcontroller continues to count and sends a command to the transducer and/or sterilizer to start operation if the time to stop sterilization lasts a preset time (e.g., 10 minutes).
