Example Embodiment

[0040] The present invention will be further described below in conjunction with the drawings.

[0041] See figure 1 , Is a flow chart of a locomotive collision avoidance method with vehicle-mounted optical detection combined with wireless network bridge communication proposed by the present invention.

[0042] Such as figure 1 As shown, a locomotive collision avoidance method combining on-vehicle optical detection and wireless bridge communication includes the following steps:

[0043] Step 101: The ground inspection agency obtains image information along the railway;

[0044] Step 102: Transmit to the train-mounted equipment in the area through the wireless bridge;

[0045] Step 103: The train-mounted equipment receives the processed image information and generates control commands and controls the locomotive.

[0046] In the embodiment of the present invention, the operating status information such as locomotive speed, position, etc. is obtained through the existing train control devi...

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...
