All-weather high-speed railway vehicle-mounted roadblock detection system and method

Abstract

The invention discloses an all-weather high speed railway vehicle-mounted obstacle detection system and method. According to the detection system, a camera lens is connected with a short wave infrared imaging device, a posture adjusting device drives the camera lens and an auxiliary lighting device to intelligently adjust the posture of the camera lens and the posture of the auxiliary lighting device in real time, the short wave infrared imaging device is connected with a vehicle-mounted master control system, the vehicle-mounted master control system is connected with a display device, an alarm device and a storage device, and a train operation monitoring and recording device interface is used for communication between the vehicle-mounted master control system and a train operation monitoring and recording device to obtain train operation and track related information. The detection method mainly comprises the steps of real-time front track image collection, image sequence frame processing, real-time camera lens and auxiliary lighting device orientation adjustment, obstacle detection and notification, and the like. According to the all-weather high speed railway vehicle-mounted obstacle detection system and method, the higher target detail resolution ratio and all-weather operation capacity are achieved, real-time communication can be carried out between the all-weather high speed railway vehicle-mounted obstacle detection system and the train operation monitoring and recording device, information such as front track information and train operation speed is obtained, and the false alarm rate can be effectively lowered.

Description

technical field [0001] The invention relates to high-speed railway safety monitoring technology, in particular to an all-weather high-speed railway vehicle-mounted roadblock detection method. Background technique [0002] Train driving safety has always been a hot research topic, especially the six major speed increases of China's railways, which have brought about major changes in railway transportation. The increase of train running speed brings more potential safety hazards and safety risks. The rapid development of high-speed railway technology has ensured the safety of my country's high-speed railways. However, due to factors such as natural disasters and man-made destruction, coupled with the high speed of trains, it is very difficult to ensure traffic safety, which is specifically reflected in: 1. During the operation of the train, if there is an obstacle on the track, the braking distance required for emergency braking will be long; 2. After the speed of the train is...

AI Technical Summary

Problems solved by technology

This utility model patent uses mid-wave infrared imaging technology for track obstacle identification, which can avoid the influence of severe weather conditions such as heavy fog and night to a certain extent, but the detection distance of this system is short, the resolution is low, and the cost is high. Infrared has poor penetration to the window glass, so the camera can only be installed outside the car body

Therefore, the system cannot meet the high-speed railway requirements
