Description
Technical field
The present invention relates to a kind of improvement of railway locomotive operational method, be specifically related to a kind of locomotive shunting job safety method for early warning and system and device, particularly how a kind of locomotive realizes following the trail of ranging technology to ensure the method and system device of job safety in shunting service, the tracking of the method and system and device applications ranging signal in locomotive shunting operation realizes monitoring safety distance in real time, belongs to rolling stock detection technique field.
background technology:
In railway transportation production process, except train arrival AT STATION, set out, by and except operation in interval, all rolling stocks carry out all to be had object to move to be referred to as and shunts.For disintegrating, marshaling, dislodgings, transition, whole field, adjust move, fetch and deliver vehicle and locomotive contraposition, turn line, the discrepancy object such as section and make the operation of rolling stock movement on station track or All other routes.It is one of substance of railways train operation work.Shunt and can be divided into by its object:
1, break-up of trains, decomposes shunting in each given line by the vehicle in car team or car group by certain requirement (if loaded vehicle is by whereabouts, empty wagons is by car type, and bad car is by maintenance place etc.).
2, make up of trains, according to relevant regulations, vehicle is weaved into car team or car group.
3, the shunting of dislodging vehicle, for train is mended axle, subtracts axle, changed trailer group or dislodging vehicle.
4, taking out and placing in of cars, for the objects such as handling goods or maintenance vehicle fetch and deliver vehicle to operating location.
In addition, vehicle arrangement etc. is also had in car team and the transition of car group, the inspection weighing apparatus of lorry, field to shunt, and locomotive etc. of letting pass on station track.
Existing shunting service, usually carried out by an each rolling stock of locomotive traction and disintegrate or docking, certain operating risk hidden danger is had thus when shunting docking rolling stock, in the operation process of numerous and diverse high frequency time, locomotive causes the slow hook of large vector crash vehicle tractor truck when connecting rolling stock because visual angle is unclear, range estimation is slipped up, thus the coupling hitch of spoiled work shunter.In order to ensure safety, in this operation process, working truck Crane Rail direction needs headroom to ensure the safety of personnel and equipment, therefore it is particularly important clearly can to reflect locomotive driving spatial domain, this point do not accomplished by existing locomotive, is badly in need of being improved this.
Do not find that there is the patent literature constructed with the present invention by patent retrieval, to have the patent of certain relation to mainly contain following with the present invention:
1, the patent No. is CN201210171566, name is called the patent of invention of " a kind of electric locomotive shunt control method, Apparatus and system ", which disclose electric locomotive to shunt control method, for realizing the control of shunting of electric locomotive, the method comprises: after receiving the control activation instruction of shunting of intelligent display unit transmission, activate master mode of shunting; Receive the secondary contact signal that driver's cab input-output unit collects, according to secondary contact signal determination locomotive state; Obtain maximum traction value/maximum brake value, and receive the voltage output signal that driver's cab input-output unit collects, obtain tractive force value request/braking force value request according to maximum traction value/maximum brake value and voltage output signal; According to tractive force value request/braking force value request, obtain the tractive force numerical value/braking force numerical value of locomotive when shunting; Send tractive force numerical value/braking force numerical value to traction control unit, make traction control unit according to tractive force numerical value/braking force numerical value for locomotive provides required drag torque/lock torque.
2, the patent No. is CN201120350593, and the patent of invention that name is called " the anti-Ore-controlling Role of a kind of railway locomotive shunting operation safety ", which discloses the anti-Ore-controlling Role of railway locomotive shunting operation safety, relate to railway locomotive application.Comprise the industrial control host and image collecting device that are connected by netting twine, in the locomotive all arranged, by vehicle-mounted 110 volts of powered by direct current; Main frame control device through 485 lines be connected with row, monitor enter shunt state time, transmit control signal to image collecting device, control image acquisition device pathway information; Main frame identifies Traffic signal color from image, if blue or red, transmits control signal to the voice device be attached thereto.Main frame is from row control device reading machine vehicle speed, and when being less than stopping distance, locomotive speed does not reach deceleration demand, forces to export 110V direct current (DC) to exhaust valve emergency brake by 485 power supply module for communication.
3, the patent No. is CN200910306240, and the patent of invention that name is called " distance meter for shunting of railway locomotive and distance-finding method thereof ", which discloses a kind of distance meter for shunting of railway locomotive and distance-finding method thereof.It is simple that it has structure, easy to use, coordinate circuit geographic information data, operating range needed for objects ahead and current vehicle speed can be calculated in real time, the advantages such as auxiliary shunter finishes the work, its structure is: it is made up of difference station and hand-held set, and wherein difference station is its employing wireless mode broadcast DGPS difference correction information of computing machine; Hand-held set comprises microcontroller, and microcontroller is connected with FLASH memory, GPS, keyboard, LCDs, wireless receiving module, voice module and interface circuit respectively; Battery provides electric power for the work of whole equipment.
So although these patents above-mentioned all relate to shunting railway locomotives operation, the safety monitoring having related to shunting service wherein also had or range finding, but all function singlenesses, system architecture is complicated, be difficult to accurately position operation, therefore in the operation process of numerous and diverse high frequency time, locomotive causes the slow hook of large vector crash vehicle tractor truck when connecting rolling stock because visual angle is unclear, range estimation is slipped up, thus the problem of the coupling hitch of spoiled work shunter still exists, still need to be improved further.
