Method and device for locomotive anticollision using optical detection mechanism to track steel rail track

Abstract

The invention discloses a method for locomotive anticollision using an optical detection mechanism to track a steel rail track. The method comprises the following steps: using an image pickup mechanism to extract image information of calibration zones of a steel rail track and an entrance in front of a locomotive according to various characteristics of various images of tracks and barriers; performing analytic calculation and analytical judgment on information of the image pickup mechanism; and controlling the locomotive. The invention also discloses a device for locomotive anticollision using an optical detection mechanism to track a steel rail track. A far infrared or CCD detection device is used to track the calibration zones and the entrance of the steel rail track, and through determining whether images of the calibration zones and the entrance of the steel rail track are covered by the barriers, barrier early warning and barrier consist are used to issue a braking instruction to a locomotive braking system, so as to realize locomotive anticollision. The device can still detect required safety distances at night and in rainy, snowy, and foggy weather conditions, the device can operate in all weather, and provides important guarantee for traffic safety.

Description

technical field [0001] The invention relates to the field of railway safety operation, in particular to a locomotive anti-collision method and device for tracking rail tracks by using an optical detection mechanism. Background technique [0002] The current anti-collision method of the railway is the block driving method. It is judged whether the line ahead is free through the block section. The disadvantage of this technical method is that even if the line is confirmed to be free, there are still obstacles in the blocked section, such as: the two rails are not conductive due to various reasons (poor electrical conductivity of the rails, poor electrical conductivity of the wheels, and obstacles are non-conductive objects) At this time, all obstacles on the rails cannot be detected; vehicles, landslides, floods, etc., cannot be detected by existing technical means, so train collision accidents occur. [0003] Also based on the driver's visual inspection, this is completely s...

Problems solved by technology

However, the braking distance of the locomotive is at least 800 meters, plus the distance covered by the driver's reaction time, it is impossible to avoid accidents

Most of the major traffic accidents usually occur in the middle of the night, when the driver's physical fitness declines, the weather conditions are bad, and there is no scientific means of prevention and control. This is a major hidden danger to driving safety.
