Telescopic laser scanning detection system suitable for platform door and control method of telescopic laser scanning detection system

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...

Problems solved by technology

However, the two systems also have corresponding limitations. For example, for the infrared detection system, because the divergence angle and spot of the beam emitted by the infrared emitting tube are often large, the power density attenuation is large during transmission, and it is easy to appear when transmitting in a narrow gap. Due to random reflection phenomenon, false alarms or random alarms occur, resulting in poor accuracy; and for laser detection systems, due to the straight-forward nature of laser transmission, there is a certain blind spot in the detection of parallel laser beams, and the detection accuracy cannot be fully obtained. At the same time, the above two systems often need to invade the train boundary when setting, which has a certain impact on the stability of the detection system and the safety of the train operation, and cannot fully meet the requirements of the detection system on the platform; in addition, During the long-term use of the above two detection systems, the displacement is usually caused by the vibration of the environment, resulting in deviations in the detection process and error reporting, which requires frequent manual repairs and maintenance, which increases the operating cost of the station and causes great inconvenience
