Signal-transmission type motor sudden stop control system

Abstract

The invention belongs to the technical field of elevator safety and discloses a signal-transmission type motor sudden stop control system. The system comprises a power source, a sudden stop controller, a motor, a wire harness, infrared monitors, a thermal imagery analyzer and stress sensors, the power source, the sudden stop controller and the motor are all arranged below an escalator, steps of the escalator are driven by the motor to move, the first infrared monitors are symmetrically arranged on an escalator outlet plate, and the second infrared monitors are symmetrically arranged on an escalator handrail plate. According to the signal-transmission type motor sudden stop control system, the sudden stop controller can judge the degree of crowdedness at the escalator exit according to the circumstance monitored by the first infrared monitors; when crowdedness or stampede accidents occur at the exit, the sudden stop controller controls the motor to stop running in time. The system is reasonable in design, simple in structure and applicable to optimization design for an escalator crowdedness or stampede accident impairment-reduction system.

Description

technical field [0001] The invention belongs to the technical field of elevator safety design, and specifically relates to a signal transmission type motor emergency stop control system which can identify crowding of people or trampling accidents in an escalator 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...
