Platform door swing type anti-pinch one-way detection system based on thermal imaging and control method

Abstract

The invention discloses a platform door swing-type anti-pinch one-way detection system based on thermal imaging. The platform door swing-type anti-pinch one-way detection system is characterized in that a swinging mechanism is installed in an end door stand column at the joint of one end door (4) of a platform door and a fixed door; a steering engine mounting groove (5) and a swing support mounting groove (7) are formed in the end door stand column in a hidden mode, a steering engine (6) and a swing support (8) are respectively arranged, and the steering engine (6) drives the swing support (8)and a thermal imaging collector (9) to conduct two-stage swing at the angle of 0-90 degrees. The swinging mechanism is adopted, the mechanism is retracted when rail transit vehicles such as subways run, and it is guaranteed that a limit is not invaded; the mechanism swings out and collects thermal images when the vehicle arrives at the station. The thermal imaging technology is based on the principle of thermal radiation, the action distance is long, the penetrability is high, the limitation of ambient light and illumination light is avoided, and the detection stability of the detection device is greatly improved.

Description

technical field [0001] The invention belongs to the field of new urban rail transit, and in particular relates to a platform door swing compound anti-pinch one-way detection system and a control method based on thermal imaging. Background technique [0002] During the actual operation of the subway line, there have been accidents in which passengers were caught between the closed platform door and the train door. Still squeeze into the car forcibly when closing and a safety accident occurs. [0003] Problem 1: Infrared or laser beam-to-shoot devices have a long distance to shoot, and a slight deviation can affect the recognition rate of shoot-to-shoot. [0004] Problem 2: The existing infrared or laser anti-trap solutions have the problem of intrusion limit. [0005] Question 3: The direct-to-radio device is easily disturbed by the environment and is unstable. Contents of the invention [0006] Aiming at at least one of the above defects or improvement needs in the prio...
