Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the photoelectric sensor array 1 has a plurality of units, which are arranged at intervals along the direction of the escalator, and each unit is installed on the apron boards on both sides of the escalator, and each unit has two groups of photoelectric sensors. The output of the sensor array is sent to the second judgment controller. The output of the photoelectric sensor is determined by whether the laser generated by one side is received by the other side (that is, whether there is an object blocking the optical path). Under normal circumstances, the upper and lower sets of sensors in the same unit either detect the presence of objects on the optical path (that is, there are passengers currently in the unit) or neither detect the existence of objects in the optical path (that is, there are no passengers in the unit at present). lo...

Abstract

The invention discloses an automatic-ladder-matched safety device. The automatic-ladder-matched safety device specifically comprises photoelectric sensor arrays respectively used for detecting body postures of passengers (whether an abnormal posture such as falling appears or not), pressure sensor arrays for detecting gap pressure between steps and steps and gap pressure between steps and skirt guard panels, magnetic sensors for detecting the running speed and the direction of an elevator, first judging controllers for judgment according to pressure sensor array outputting, second judging controllers according to photoelectric sensor array outputting and magnetic sensor outputting, warning device arrays for sounding warnings to the passengers and scramming devices for elevator scramming. The automatic-ladder-matched safety device has the functions of detecting insecurity and accident behaviors of the passengers and the abnormal running conditions of the elevator, is thoughtful, and can effectively prevent security accidents from occurring.

Description

technical field [0001] The invention relates to the field of public facilities, in particular to a safety device for an escalator. Background technique [0002] As a public facility, the escalator has changed people's way of life and has become an important symbol of modern material civilization, which greatly facilitates people's lives, especially for people with walking disabilities. It is a great invention. With the further deepening of my country's urbanization process, a series of public transportation infrastructure projects have been launched one after another, and escalators, as an indispensable part of these facilities, will become more and more common. But people should also clearly realize that escalators also bring many safety hazards. The main causes of safety accidents are as follows: [0003] (1) Accidentally fall while taking the escalator, but the escalator is still running; [0004] (2) toes caught in the gap between the elevator steps and the apron (sid...
