Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to make those skilled in the art more fully understand the present invention program, with reference to the accompanying drawing and it is embodied
The present invention is described in further detail for mode.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 is the control method of adaptive train pipe level pressure provided by the embodiment of the present invention
Flow chart；Fig. 2 is the structural block diagram of the control system of adaptive train pipe level pressure provided by the embodiment of the present invention.
A kind of control method of adaptive train pipe level pressure provided by the invention, specifically includes that
Under static state, judge whether traction locomotive starts to carry out release of brake；If so, performing the next step；
The change rate of the pressure of train pipe is judged whether within the scope of default change rate, if so, performing the next step；
Level pressure is judged according to the pressure of the train pipe；
Under driving status, judge whether traction locomotive applies braking；If so, performing the next step；
In the fixed situation of train pipe level pressure, according to the linear of railcar deceleration demand and train pipe pressure reduction
Relationship carries out control for brake to railcar.
Reference book attached drawing 1 is it is found that step S10 starts to execute, in step S20, judge traction locomotive speed whether be
Zero；When the speed of traction locomotive is zero, step S30 is executed, judges whether the amount of boost of the pressure of train pipe is greater than 20kPa.
Wherein, step S20 can be decomposed into two steps, and the first step first obtains the speed of traction locomotive；Second step is to dragger
The speed of vehicle is judged；Only when the speed of traction locomotive is zero, then it can be performed and " judge the amount of boost of the pressure of train pipe
The step of whether being greater than 20kPa ".
That is, the speed when traction locomotive is zero, and microcomputer control unit detects that train tube pressure is increased beyond 20kPa
When, then illustrate that braking starts to alleviate；" under static state, judging whether traction locomotive starts to carry out release of brake " is as above-mentioned
Step S10~step S30.
After braking starts alleviation, judge the change rate of the pressure of train pipe whether within the scope of default change rate；At this
In, whether the change rate that can execute the pressure for judging train pipe is less than 5kPa/s, such as step S40, namely needs train pipe
Pressure carries out level pressure judgement to train pipe after stablizing.
The step of level pressure judgement is carried out to train pipe namely the process that level pressure is judged according to the pressure of the train pipe, step
In S50, judge whether the pressure of train pipe is less than or equal to 530kPa, and whether is more than or equal to 560kPa；When the train pipe
Pressure be less than or equal to 530kPa when, by train pipe level pressure be 500kPa；When the pressure of the train pipe is more than or equal to 560kPa
When, it is 600kPa by train pipe level pressure.
Since the train pipe level pressure of current China railways vehicle is divided into 500kPa and two kinds of 600kPa, passed through in conjunction with practical
Test, the pressure of train pipe usually be less than or equal to 530kPa or be more than or equal to 560kPa in the range of, therefore, when the train
It is 500kPa by train pipe level pressure when the pressure of pipe is less than or equal to 530kPa；When the pressure of the train pipe is more than or equal to
It is 600kPa by train pipe level pressure when 560kPa；Such as step S60 and step S70.
It for the above process, may be summarized to be: train tube pressure being detected by pressure sensor, output controls single to microcomputer
Member.When microcomputer control unit detects that stationary vehicle, train tube pressure are increased beyond 20kPa, braking starts to alleviate, and detects train
Pipe pressure, when train tube pressure stablize after (train tube pressure change rate < 5kPa/s), train pipe level pressure is judged, if
The train tube pressure detected at this time is more than or equal to 560kPa, then judges current train pipe level pressure for 600kPa；If examined at this time
The train tube pressure measured is less than or equal to 530kPa, then judges current train pipe level pressure for 500kPa.
So far, the movement of rail vehicle under static state finishes, and then, rail vehicle brings into operation；In driving status
Under, judge whether traction locomotive applies braking；During judging whether traction locomotive applies braking, the column are obtained first
The decompression rate and decompression amount of vehicle pipe；Then judge whether the decompression rate of the train pipe is more than or equal to 10kPa/s, and sentence
Whether the decompression amount of the train pipe of breaking is more than or equal to 40kPa, if being to be, the traction locomotive is applied braking, namely
Execute step S61 and step S71.
That is, microcomputer control unit is by calculating train pipe decompression rate and decompression amount, conversion after train pipe level pressure determines
And the PWM instruction that railcar can identify is exported, control the braking and alleviation of subway train.
It no matter for train pipe level pressure is 500kPa or in the case of train pipe level pressure is 600kPa, if without system is applied
It is dynamic, then continue to keep relieved state, such as step 62 and step S72；When the brake has been applied, then specifically to distinguish train pipe level pressure is
The situation that 500kPa and train pipe level pressure are 600kPa.
Specifically, in the fixed situation of train pipe level pressure, subtracted according to railcar deceleration demand with train pipe
The step of linear relationship of pressure amount carries out control for brake to railcar can refer to step S63 and step S73；
Permutation vehicle is braked according to formula a=0.004b+0.04；Wherein, the deceleration of permutation vehicle is a, column
The decompression amount of vehicle pipe is b；
When train pipe level pressure is 500kPa, the decompression amount b of train pipe is 40kPa~140kPa；Then permutation vehicle subtracts
Speed a is 0.2m/s2~0.6m/s2；
When train pipe level pressure is 600kPa, the decompression amount b of train pipe is 40kPa~170kPa；Then permutation vehicle subtracts
Speed a is 0.2m/s2~0.72m/s2。
In other words, after train pipe level pressure, brake control process in the process of moving are as follows:
When train pipe level pressure be 500kPa when, train pipe maximum decompression amount be 140kPa, when detect train pipe decompression speed
When rate >=10kPa/s, record train pipe reaches the starting instantaneous pressure when decompression rate, and using this pressure as reference pressure
Value, unless train, which issues, alleviates instruction, otherwise the reference pressure value should immobilize；If collected instantaneous pressure value with should
The difference of reference pressure, i.e. decompression amount are less than 40kPa, then braking deceleration is zero, when decompression amount is not less than 40kPa, subway
Vehicle applies braking, and train pipe pressure reduction is between 40kPa and maximum decompression amount, and the subway train rate of deceleration is in 0.2m/s2~
0.6m/s2Between linearly correspond to；
When train pipe level pressure be 600kPa when, train pipe maximum decompression amount be 170kPa, when detect train pipe decompression speed
When rate >=10kPa/s, record train pipe reaches the starting instantaneous pressure when decompression rate, and using this pressure as reference pressure
Value, unless train, which issues, alleviates instruction, otherwise the reference pressure value should immobilize；If collected instantaneous pressure value with should
The difference of reference pressure, i.e. decompression amount are less than 40kPa, then braking deceleration is zero, when decompression amount is not less than 40kPa, subway
Vehicle applies braking, and train pipe pressure reduction is between 40kPa and maximum decompression amount, and the subway train rate of deceleration is in 0.2m/s2~
0.72m/s2Between linearly correspond to.
Using above-mentioned control method, when train pipe level pressure is when 500kPa and 600kPa switches, the braking control of railcar
System again can sentence train pipe level pressure without personnel according to the transformation of adaptive train pipe level pressure, railcar control for brake
Disconnected and confirmation, avoids the occurrence of artificial error in judgement.
