Method and device for locomotive anticollision using on-board optical detection mechanism combining with auxiliary image pickup

Abstract

The invention discloses a method for locomotive anticollision using on-board optical detection mechanism combining with auxiliary image pickup. The method comprises the following steps: extracting image information of calibration zones of a steel rail track and an entrance through the on-board optical detection mechanism and an auxiliary image pickup mechanism; analyzing and determining extracted image information; and controlling operation of a locomotive. The invention also discloses a device for locomotive anticollision using on-board optical detection mechanism combining with auxiliary image pickup. A detection base station formed by far infrared or CCD and image identification, data processing, fault early warning, and consist information sending technologies, and full coverage detection of rail tracks without blind areas is realized. The ground detection base station is static, and aims at the detected zone of steel rail track to determine whether an external object invades. The device sends fault instructions and monitoring images to the locomotive through a wireless bridge technology, so as to realize locomotive anticollision. The device can still detect required safety distances at night and in rainy, snowy, and foggy weather conditions, 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 in which a vehicle-mounted optical detection mechanism is combined with an auxiliary camera. 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 inspe...

AI Technical Summary

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.
