Method and device for locomotive anticollision using on-board optical detection combining with wireless bridge communication

Abstract

The invention discloses a method for locomotive anticollision using on-board optical detection combining with wireless bridge communication. The method comprises the following steps: a ground detection mechanism obtaining image information along the railway; transmitting the information to a train on-board device in the region through wireless bridge; and the train on-board device receiving processed image information and generating a control command and controlling a locomotive. The invention also discloses a device for locomotive anticollision using on-board optical detection combining with wireless bridge communication. Communication among acquisition devices and an on-board control device along the railway is realized through the wireless bridge. The device and the method determine whether steel rails are covered by barriers, so as to realize locomotive anticollision. The device and the method can still detect required distances ensuring safety at night and in rainy, snowy, and foggy weather conditions. The device can operate in all weathers, 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 with vehicle-mounted optical detection combined with wireless network bridge communication. 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 inspec...

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.
