Abstract

The invention relates to a rail transit obstacle detection method. The method comprises the steps that: a laser detection device is controlled to measure the rail width of each position of a rail in atarget area in the advancing direction of a rail transit train; the measured track width of each position of the track is compared with a train rail standard, so that calibration parameters corresponding to each position of the rail can be obtained; laser detection is continuously carried out on the target area to determine whether an obstacle exists in the target area; if the obstacle exists inthe target area, a first state of the obstacle is detected; and the first state is calibrated by using the calibration parameter of the rail position corresponding to the obstacle, so that a second state of the obstacle is obtained, and therefore, obstacle detection of rail transit can be realized. According to the method, the state of the detected obstacle is calibrated, so that the state of thedetected obstacle is more accurate, risk estimation can be carried out on a moving object with a collision risk, and the safety of rail transit during operation is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rail traffic safety, and in particular relates to a rail traffic obstacle detection method and device. Background technique [0002] In recent years, domestic high-speed railway projects have developed rapidly. High-speed railways can achieve operating speeds of 250km / h to 380km / h, and even some maglev trains can reach operating speeds of 600km / h. It has brought more convenience to people's travel. As of the end of 2019, my country's railway operating mileage has reached more than 139,000 kilometers, including 35,000 kilometers of high-speed railways, ranking first in the world. [0003] However, while the high-speed railway brings convenience to people's travel, due to its high speed, it naturally increases the risk of encountering obstacles. Therefore, it is necessary to provide an efficient obstacle detection and risk estimation scheme to ensure that the train security of operation. Contents of the ...
