Description
Technical field
The present invention relates generally to a kind of electric braking force control method and control setup that is used for rolling stock.
Background technology
At present, rail vehicles is in order to reduce power-absorption fan, and the especially wearing and tearing of friction brake reduce maintenance and upkeep cost, reduce brake oil, at general air brake of glancing impact and electric brake Associated brake, preferentially adopts electric braking to brake automatically.
Common so far electric braking force control method generally has two kinds: first kind is direct control.Control setup (as driver controller) by electric braking force directly applies electric braking to rolling stock, and the size of electric braking force is determined by the controller level position, and is irrelevant with air brake; Second kind is the output of controlling electric braking force by the air brake controller, utilizes electric braking force to replace air brake power.The implementation method of present this situation is: implement braking by the air brake controller, make brake pipe's decompression of rolling stock, measure distributing valve brake pipe's (train pipe) force value by pressure checking device, send control system to and calculate the decompression amount that a certain section time inside brake is responsible for, go out this brake pipe's decompression according to the brake calculated with mathematical model of being set up again and measure pairing air brake power size, the electric braking force of output equivalent then is to reach the effect that replaces air brake.
Above-mentioned by the air brake controller, control the method for electric braking force in conjunction with the brake math modeling of setting up, need set up corresponding math modeling at different air damper systems, commonality is not strong, and computation process shows complicated slightly.Because need the input interior train pipe pressure reduction of section sometime, system's control has certain time delay, lacks real-time and particularity.
Summary of the invention
At the problem that prior art exists, purpose of the present invention aims to provide a kind of electric braking force control method and control setup that is used for rolling stock, can effectively improve accuracy and real-time, is convenient to application, highly versatile simultaneously.
In order to realize the foregoing invention purpose, the technical scheme that the present invention takes is that a kind of electric braking force control method that is used for rolling stock adopts pressure checking device to gather the air pressure value of distributing valve effect pipe; This air pressure value that collects is delivered to controller, and controller converts air pressure value to required electric braking force through calculating; Last controller is made corresponding operating according to the electric braking force control electric braking drive element that calculates, and realizes the braking force output of electric brake.
With above-mentioned control method be accordingly, the present invention also provides a kind of electric braking force control setup that is used for rolling stock, it comprises pressure checking device, controller and electric brake drive element, it is characterized in that, described pressure checking device is positioned in the rolling stock distributing valve effect pipe, and the signal input part of the signal output part access controller of this pressure checking device, the signal output part of controller inserts the electric brake drive element.
As embodiment, what above-mentioned pressure checking device adopted is conventional pressure sensor.
Principle of work of the present invention is: in rolling stock distributing valve effect pipe, be provided with the pressure checking device that detects its internal air pressure, and the mouth access controller of described pressure checking device, the mouth of described controller inserts the electric brake drive element.When rolling stock is controlled electric braking force by the air brake controller, pressure checking device is directly measured effect pipe (brake cylinder control tube) air pressure of output after distributing valve calculates and controls, be desired air brake power, be real-time transmitted to controller and calculate conversion, export corresponding electric braking force at last, realize the accurate braking of locomotive.
Compared with prior art, of the present inventionly be used for the electric braking force control method of rolling stock and the advantage of control convenience is:
The measured effect pipe of the present invention air pressure can be real-time send to controller, just can control the output of electric braking force through simple conversion back, need not to calculate required air braking force size as the decompression amount of utilizing the train pipe in the section sometime in the prior art, make The whole control have more real-time, also simplified whole control process, need not to set up complicated mathematical model, whole control process is simple and reliable, reduced the error accumulation of calculating link, made that control is more accurate; The method of the invention and control convenience are simple, can realize simply and easily that commonality is stronger on the rolling stock that has been equipped with electric braking drg and power-absorption fan.
