when the mains supply is powered off:
there is a process for the voltage at the first power supply interface a to drop from 20v to 1v, the first time point of the first interface level from the first level state to the second level state is the point C shown in fig. 6a, the corresponding output is the a interface level L1 logic signal in fig. 7a, and the first time point of the first interface level from the first level state to the second level state is the point P1 shown in fig. 7 a; there is a process for the voltage at the second power supply interface B to drop from 20v to 16.8v, the second time point of the second interface level from the first level state to the second level state is the point D shown in fig. 6a, the corresponding output is the B interface level L2 logic signal in fig. 7a, and the second time point of the second interface level from the first level state to the second level state is the point P2 shown in fig. 7 a; at this time, the time difference between the first time point C and the second time point D and between the first time point P1 and the second time point P2 is about 500ms, so that the reason of power failure can be determined as the power failure of the mains supply, that is, the reason of power failure is the second power failure reason, and the current running state of the cleaning equipment is maintained;
