step S10, a tapping signal applied to the door body is acquired.

When the user has a need to open the door 120, the user taps on the door so that the sensor 130 acquires a tap signal applied to the door 120, and the sensor 130 transmits the acquired tap signal to the controller 150.

Step S20, analyzing the knocking signal, and opening the door body according to the knocking signal.

The controller 150 receives the striking signal transmitted from the sensor 130, performs an analysis process on the striking signal, for example, performs an amplification process on the striking signal, removes interference information, and accumulates the number of striking times N applied to the door 120 within a predetermined period of time; when n=1 is resolved, the door 120 is opened to correspond to the lighting device in the compartment; when N is greater than or equal to 2, the door 120 of the compartment is opened. Wherein the predetermined period of time may be set between 0s and 5s while the predetermined period of time should not be too long, otherwise the risk of misopening the door 120 may be increased.
