Laser scanning anti-clamping system suitable for rail traffic station door and control method of laser scanning anti-clamping system

Abstract

The invention discloses a laser scanning anti-clamping system suitable for a rail traffic station door and a control method of the laser scanning anti-clamping system, and belongs to the technical field of station door security detection. End doors at the two ends of a station are provided with a laser scanning unit and a laser receiving unit correspondingly, a scanning steering engine, a rotatingmotor and a rotating shaft are correspondingly arranged, through control of corresponding rotating motor, an anti-clamping system extends into or be away from a train limit, and surface scanning detection of lasers is achieved through corresponding control of the scanning steering engine. According to the laser scanning anti-clamping system, the structure is simple, arrangement is simple and convenient, surface scanning detection of human or objects between a station door assembly and a train body can be effectively achieved, safety of station operation is ensured, precision of detecting is high, the error is small, the train limit is not invaded by the anti-clamping system during train operation, stability of train operation can be fully ensured, damage on the train body of the anti-clamping system is reduced, the service lift of the anti-clamping system is also long, and the laser scanning anti-clamping system has good application prospects and promotion value.

Description

technical field [0001] The invention belongs to the technical field of platform door safety detection, and in particular relates to a laser scanning anti-pinch system suitable for rail transit platform doors and a control method thereof. Background technique [0002] With the continuous acceleration of urbanization, the application of rail transit is becoming more and more common. Compared with other urban transportation systems, rail transit has a large capacity and high punctuality rate, which can greatly facilitate people's travel, and rail transit often does not occupy the road space of cars and buses, which is very important for improving urban congestion. significant effect. [0003] During the operation of rail transit, a platform door system is generally installed on the platform to separate the platform from the track and realize passengers' getting on and off. Due to the consideration of the train limit during the train operation, the setting of the platform door...

Problems solved by technology

However, due to the straight-forward nature of laser transmission, there is a certain blind spot in the detection of parallel laser beams, and the accuracy of detection cannot be fully guaranteed. In addition, the existing laser detection system often needs to invade the limit, so the setting of the detection system is stable. There is a certain impact on safety and train operation safety; at the same time, during the long-term use of the existing laser detection system, it usually displaces due to the vibration of the environment, resulting in a deviation in the alignment and reporting an error, which requires frequent manual repairs and maintenance. , increasing the operating cost of the station, causing great inconvenience
