Abstract

The invention relates to a train protection system and method based on laser detection. The train protection system comprises a laser sensor module used for emitting laser pulses to the front side of a current train and receiving echo pulse information, an electronic map positioning module used for acquiring the current position of the train, information whether the train is located at a curve and curve curvature information when the train is located at the curve, an information acquisition and storage module acquiring and storing the above echo pulse information in real time, and a data processing and analysis module used for acquiring distance measurement data, the current position of the current train and/or the curve curvature information to adjust the running speed of the current train. By the adoption of the system, only corresponding equipment needs to be installed at the front portion of the train, ground equipment does not need to be installed on each station, dependence on the normal working states of other trains is not needed, the occupied train-mounted space is small, and installation is easy and convenient. Meanwhile, the system can serve as an auxiliary system for an ATP system, the train collision possibility is reduced, and the train traveling safety is improved.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a laser detection-based train protection system and method. Background technique [0002] In the prior art, automatic train protection system (Automatic Train Protection, ATP) is used in urban rail transit for train safety protection, that is, positioning equipment, communication equipment and detection equipment for ground stations are installed on each train, and communication is carried out between each equipment, through Track trains to prevent rear-end collisions. [0003] In order to detect the train ahead, a company designed a system for detecting obstacles ahead of a rail train, which consists of a camera, millimeter-wave radar and a track control unit. The images collected by the camera are used to identify obstacles, and according to the speed The variable determines the distance to the obstacle and calculates the possibility of collision with the vehicle in front, thereby ...
