Description
Technical field
The present invention relates to train braking technical field, specifically a kind of train braking fault judgment method.
Background technique
Train braking can be divided into " service braking " and two kinds of " emergency braking " by purposes in manipulation.It is under normal circumstances
It adjusts or control train speed includes the braking that inlet parking is implemented, referred to as " service braking ", its feature is that effect is compared
It mitigates and brake force is adjustable.In case of emergency to make train stop implemented braking as early as possible, referred to as " urgent system
Dynamic " (also referred to as " emergency brake "), its feature be act on it is relatively swifter and more violent and also train braking ability all with.
From implement braking moment, the moment for being reduced to zero to train speed stops, the distance that train crosses, referred to as braking away from
From.This is the key technical indexes of concentrated expression train braking device performance and effect.The weight of train is bigger, and the speed of service is got over
Height is just less susceptible to stop in short time, short distance.
And undesirable emergency braking once occurs for train, then needs temporary parking, is listened by inspection vehicle personnel compartment ear one by one of getting off
And visual inspection, while segmentation release of brake test is carried out by driver's compounding practice, undesirable emergency braking occurs first for positioning
Vehicle after the debugging that takes measures, can continue to run.It is limited by train marshalling list length and parking environment, positioning failure vehicle
It need to generally take a long time, influence the operation of other main track trains since the line is busy, it is late to often result in train large area, sternly
Ghost image rings train operation.

Further, in order to preferably realize that the present invention, the vehicle grade failure include not making caused by main valve failure
Improper release caused by improper release, empty and load failure caused by not braking, main valve failure caused by dynamic, empty and load failure, from
Right braking, natural remission, checking cylinder are sewed.
Further, in order to preferably realize that the present invention, the train grade failure include shutdown vehicle failure, angle cock
It closes, train pipe is sewed, undesirable emergency braking.
Further, in order to preferably realize the present invention, according to motor vehicle braking system train pipe and/or rail vehicle train
Pipe pressure exception is by first bus until trailer judges that angle cock is closed；According to motor vehicle braking system train pipe and/or rail vehicle
Train tube pressure is abnormal non-until trailer judges shutdown vehicle failure by first bus.
Further, in order to preferably realize the present invention, first is judged according to the chronological order of undesirable emergency braking
The vehicle of undesirable emergency braking.
Further, in order to preferably realize the present invention, according to motor vehicle braking system train pipe and/or rail vehicle train
The vehicle location that the sequencing that pipe is sewed sews train pipe.
Beneficial effect acquired by this programme is: by the air pressure variations on train braking system critical path into
Row monitoring can accurately collect pressure change data in real time, and the quickly type and location of fault of fault analysis and judgement,
The time of investigation failure can be shortened, improve the efficiency of investigation failure.
