Abstract

The invention discloses a method and a device for detecting an overspeed and nonmanipulated reversal protection function of an automatic stair/way. The method is used for accurately controlling the operation speed and the operation direction of the automatic stair/way by adopting a frequency conversion technology to simulate the dangerous working conditions of the automatic stair/way and detect whether the overspeed and nonmanipulated reversal protection function of the automatic stair/way meets related standards under the simulated dangerous working conditions, is free from the limitation of an overspeed or nonmanipulated reversal protection function realization mode of the automatic stair/way with regard to implementation and is suitable for detection of overspeed and nonmanipulated reversal protection devices of various automatic stairs/ways. The device comprises a shell, wherein a control chip and a frequency converter are arranged in the shell, and two aviation connectors are arranged on an external panel of the shell; and the device is connected with a control cabinet of the automatic stair/way to be detected through the two aviation connectors. The method can be used to realize the detection of the overspeed and nonmanipulated reversal protection function of the automatic stair/way to be detected.

Description

technical field [0001] The invention belongs to the technical field of safety protection function detection of an escalator / way, and specifically relates to a detection method and a corresponding device for the overspeed and non-manipulation reverse protection function of an escalator / way. Background technique [0002] The so-called overspeed of the escalator / way or moving walkway (referred to as the escalator / way) refers to the fact that the escalator / way is running downward due to some reasons (such as excessive flow of people or motor failure) causing the steps to fall under the weight of passengers. A dangerous phenomenon of accelerating downward running under the action. [0003] The so-called non-manipulated reversal of the escalator / way refers to the process of the escalator / way running upwards to transport passengers. Drive system rupture, etc.) causes the steps or belts to decelerate and stop rapidly under the weight of passengers, and then start to accelerate down...
