Thermal-image-assisted motor operation control mechanism

Abstract

The invention belongs to the technical field of escalator safety design, and provides a thermal-image-assisted motor operation control mechanism which comprises a power supply, an emergency stop controller, a motor, a wiring harness, infrared monitors, a thermal image analyzer and force sensors. The power supply, the emergency stop controller and the motor are all arranged below an escalator, and escalator steps are driven by the motor to operate. The first infrared monitors are symmetrically arranged on an escalator outlet board, and the second infrared monitors are symmetrically arranged on escalator handrail boards. According to the thermal-image-assisted motor operation control mechanism, the emergency stop controller can judge the crowding degree of people at an outlet of the escalator according to monitored conditions of the first infrared monitors; when overcrowding or stampede accidents happen to people at the outlet, the emergency stop controller controls the motor to stop operation in time. The thermal-image-assisted motor operation control mechanism is reasonable in design, simple in structure and suitable for optimization design for an overcrowding or stampede accident loss reduction system of the escalator.

Description

technical field [0001] The invention belongs to the technical field of elevator safety design, and specifically relates to a thermal imaging auxiliary motor operation control mechanism that can identify crowding of escalators or stampede accidents through a first infrared monitor. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical t...
