Description

Technical Field

[0001] The invention relates to the field of escalators, in particular to an escalator step falling detection device. Background Art

[0002] An escalator is a means of transport that transports pedestrians in the form of a conveyor belt. Escalators are generally tilted. Pedestrians stand on the automatically moving steps at one end of the escalator and are automatically taken to the other end of the escalator. The steps remain level all the way. The escalator has handrails on both sides that move synchronously with the steps for users to hold on to. Escalators can always move in one direction, but most of them can be controlled by management personnel according to time, passenger flow and other needs. Another pedestrian transportation tool that is very similar to an escalator is a moving walkway. The main difference between the two is that a moving walkway has no steps, and most of them only move on flat ground or are slightly inclined.

The traditional step fall detection device usually adopts a mounting bracket to directly fix the sensor mechanism. The installation position is generally fixed, and the detection angle remains unchanged. It cannot be adjusted according to the detection angle, which affects the accuracy of the detection result or delays the detection time. Since there are many devices in the escalator installation room and the operable space is relatively narrow, it is not convenient to install and test the step fall detection device.
