Abstract

The invention discloses a telescopic laser scanning detection system suitable for a platform door and a control method of the telescopic laser scanning detection system and belongs to the technical field of the safety detection of platform doors. According to the telescopic laser scanning detection system suitable for the platform door and the control method of the telescopic laser scanning detection system, scanning detection assemblies and driving assemblies are respectively arranged at two ends of a linear platform and corresponding to a train track area; the transverse telescopic control of the laser scanning detection system is realized through the corresponding driving of the two driving assemblies; and surface scanning detection between the platform door and the train body of a train is realized through the corresponding work of two laser beam-through units in the two scanning detection assemblies. The telescopic laser scanning detection system is simple in structure and convenient to arrange, can effectively realize scanning detection between the platform door assembly and the train body of the train and ensure the safety of the operation of a station, has high detection accuracy and just brings small error. The system does not invade the limit of the train during the operation of the train, and therefore, the setting stability of the system and the operating safety ofthe train can be fully ensured, and the safe operation of the linear platform is realized. The system has a bright application prospect and a high popularization value.

Description

technical field

[0001] The invention belongs to the technical field of platform door safety detection, and in particular relates to a retractable laser scanning detection system suitable for 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 s...
