The safety work of industry is protected, and the security protection that operation is sent on railway shunting top over long distances is particularly suitable for.Work is sent on railway shunting top
In industry, realize that real-time road image conversion is shown and barrier automatic alarm on direction of propulsion.Belong to locomotive and train work technology
Field.
Background technique:
Operation is sent on railway shunting top, is referred to using railway shunting locomotive or train locomotive, even hangs rake of wagons car team from rear end
The shunting service pushed, i.e. locomotive are relative to push direction, positioned at the tail portion of car team.Thus one problem of bring is
Driver can't see the line condition in car team direction of advance, can not break to route, the various fortuitous events such as barrier are made and
Shi Fanying, so as to cause the appearance of shunting safety accident.In order to solve the problems, such as that department's machine is looked at bad, system-wide is mainly taken off using personnel
The mode of vehicle lookout, by hand platform voice of shunting by front road condition notification driver.Personnel Ba Che lookout refers to that yardmaster is specified
One braking person or connection person, take off in car team front end first car side, look at front road conditions by Ce Shen, and in abnormal conditions
Lower sending audio alert.There are serious security hidden troubles for aforesaid way, and operation is extremely arduous.Operating personnel climbs onto a slow-going train work
Industry belongs to open work, and under the environment such as very hot extremely cold, sleet thunder and lightning, light is bad, it is right in operation especially to send on long range top
The physical strength of personnel is also greatly to test, and is fallen since fatigue, carelessness cause personnel to skid from vehicle, formation kills, weighs people wounded
The safety accident of member.This is the big safe pain spot that operation is sent on railway shunting top.Therefore, it develops a kind of railway shunting top and send operation
Safe and intelligent means of defence replaces people's air defense to be particularly important with technical precaution.
Railway shunting top send the essential problem of operation safety accident to be information asymmetry, i.e. driver can not accurately grasp vehicle
Column promote the case where forward box.It solves driver top using modern information technologies in today of information technology fast development and send work
The Qian Fang of industry looks at problem, becomes the inevitable development direction of Safety of Shunting Operation guard technology.Railway Site is sent around top of shunting
The preceding side of operation looks at electronization and has carried out many technology explorations, and technological difficulties are the delay of front-end image passback locomotive too
Greatly, it is difficult to meet the requirement of real-time that operation safety protection is sent on top.For this technological difficulties, can from image compression algorithm,
From the aspect of wireless transmission speed two, the delay of image passback is reduced.Meanwhile according to shunting service reality needs, exploitation is special
The rail track barrier automatic identification algorithm of door realizes abnormal conditions automatic alarm.
