Abstract

The invention discloses an escalator running state detection device, which comprises detected features and at least one sensor, wherein the detected features are structural features formed on a step chain of an escalator, and are components forming the step chain or additional components attached to the step chain; and the at least one sensor is arranged near the step chain, faces the detected features and is suitable for detecting the running speed of the step chain by detecting the detected features. The escalator running state detection device can detect the running speed of the step chainconveniently by directly detecting the detected characteristic on the step chain, and the cost of the detection device is reduced.

Description

technical field [0001] The invention relates to a device for detecting the running state of an escalator. Background technique [0002] The latest CEA standard for escalators used in subways, the detection of overspeed and non-operating reversal of escalators should be determined by directly measuring the step speed or the rotation speed of the main drive shaft or the sprocket assembled on the main drive shaft to determine the actual operation of the escalator speed and direction. [0003] Patent document WO2018108560A1 discloses a detection device suitable for directly detecting the rotation speed of a sprocket. The detection device needs to form a ring of high-precision gear teeth on the inner peripheral surface of the sprocket as a feature to be detected, but the cost of forming high-precision gear teeth on the inner peripheral surface of the sprocket is very high. Contents of the invention [0004] The purpose of the present invention is to solve at least one aspect ...
