Method and device for locomotive anticollision using on-board optical detection combining with geographic information

Abstract

The invention discloses a method for locomotive anticollision using on-board optical detection combining with geographic information. The method comprises the following steps: extracting steel rail track information by an on-board optical detection mechanism; combined with geographic information, performing comprehensive analysis and judgement on detection mechanism information; and controlling operation of a locomotive. The invention also discloses a device for locomotive anticollision using on-board optical detection combining with geographic information. A far-infrared or CCD detection is used to detect image information of calibration zones of a steel rail track and an entrance, combined with geographic information, accurate distance between the calibration zones and the locomotive, and the accurate distance between the entrance and the locomotive can be obtained, and an early warning distance and a consist distance are formed. Barrier early warning and barrier consist are used to release a braking instruction to a locomotive braking system, so as to realize locomotive anticollision. The method and the device provide 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 combining vehicle-mounted optical detection and geographic information. 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 comple...

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.
