If the detection signal is still present, the central control module 5 stops the escalator operation. When the warning module 6 gives an alarm, the warning module can prompt people who do not take the escalator to take the escalator temporarily and prompt people who take the escalator to hold the handrail.
And step four, danger is relieved, after the buffer unit 1 executes the buffer action, the warning module 6 continuously sends out voice warning and/or light warning to wait for the processing of workers, and after the danger is eliminated, the buffer unit 1 is restored to the initial position, and then the normal operation of the escalator can be restored.
