Side, between n fork detection module be the spaced inner side being arranged on work rail and total length more than wheel circumference, wherein,
N is L1/L2Value add 1 after round numbers, L1For wheel circumference, L2For the length of single fork detection module, in view of being detected
The wheel footpath of wheel of vehicle different, and native system is the detection of rail vehicles wheel tread flat, and its wheel footpath is general the most relatively
Greatly, as a example by electric locomotive, it takes turns footpath is 1250mm, and whole effective detection length is just greater than 3925mm.Simultaneously because
The restriction of production and processing and the limited length of fork detection module, our the fork detection module of employing of ordinary circumstance is a length of
1200mm.It is appreciated that needing four groups of fork detection modules combinations can be only achieved is detected the wheel footpath length of one week through calculating
Requirement.Fork is close to placement can produce again check frequency, therefore will realize design across putting between four sections of fork detection modules
Between requirement, and second fork detection module and the 3rd fork detection module spacing distance more than the first fork detection module and
Spacing distance between second fork detection module.Its principle is: wheel first lap, from the beginning of first fork, is leaving
Terminating in the middle of second fork and the 3rd fork detection module, namely first lap will not arrive the 3rd fork.Second circle
Begin to pass through the 3rd fork detection module, and the position that the 3rd fork detection module is mapped on wheel comprises the first fork inspection
Survey the position that the interval between module and the second fork detection module is mapped on wheel.It is further continued for by a spacer segment region,
Arrive the 4th fork detection module, and the position that the 4th fork detection module is mapped on wheel comprises the second fork and the 3rd
Interval between fork is mapped in the position on wheel.So whole week of wheel tread all will be mapped to fork detection module
On.It is also contemplated that the impact brought to different wheel footpaths and abrasion, can meet by changing the spacing distance between fork

Angle delta data after reason exports to memory element, after export to host computer communication module through communication unit.Set in installation
When putting, a marring data acquisition module is responsible for receiving the data of corresponding left and right fork detection module.Fig. 7 is railway machine
Car wheel of vehicle abrades the data acquisition module block structural diagram of automatic checkout system online.The groundwork of marring data acquisition module
Flow process is: first wheel alignment data receipt unit receives triggering signal the notification controller unit that wheel passes through, note
The record lower time triggering signal received, and according to the location parameter prestored, calculate the speed of wheel, encoder data
Receive unit and receive the marring data that on-the-spot actual acquisition arrives again, be sent to encoder data decoding unit decoding data, then send
Controller unit.Controller unit control whole system co-ordination, storage data or with host computer communication etc..
After collection in worksite has arrived the marring data of complete wheel, it is necessary to be analyzed these data processing.At railway locomotive
While vehicle passes through, host computer communication module reads one group of inlet wire and off-line marking signal from data base repeatedly, if receiving
This complete marking signal, then read the data integrated from marring data acquisition module, generates detection data file.Wipe
Hinder data analysis software, the database storage module collected is analyzed and judges, if with the presence of scratch, then according to rule
Surely carry out abrasive different brackets warning and form report log file.
Fig. 8 is that rail vehicles wheel abrades automatic checkout system scratch analysis process figure online, and the core of parser is thought
Want marring data is carried out segment processing, use traditional analytic method analysis in the region end to end of data, in data mesozone
Territory employs a kind of image that is similar to and laterally fills the analysis mode of searching.Again the result of two-stage analysis is collected, and given
Scratch length and scratch depth threshold scope, whether comprehensive descision has the existence of scratch phenomenon, and exports the position of marring data
Put, size, curve etc..
A kind of rail vehicles wheel based on the present invention abrades the detection method of automatic checkout system online, including following step
Rapid:
Step one, the head region scope pre-set on curve and tail regional extent；
Step 2, the angle delta data pressed down by wheel rim are converted into the depth displacement data that wheel rim is pressed down, to adopt
Sampling point is abscissa, and depth displacement value is vertical coordinate, it is thus achieved that primitive curve；Head region, tail regional extent to primitive curve
Interior data and curves is fitted process and obtains new curve, corresponding to the sampled point identical with on primitive curve by this new curve
Depth displacement value is subtracted each other respectively and is obtained the first difference, then the first difference carries out envelope and smooth interpolation process, forms scratch
Profile；When the vertical coordinate that there is a certain sampled point on scratch profile meets default scratch depth threshold scope, then
Now wheel is abraded, and obtains abrasive position, the degree of depth, length information；Car data and present work is crossed according to on-the-spot reality
Making the passing detection experience of personnel, abrasive existence is to characterize with length and the degree of depth, obtains when detecting for this comprehensive analytic induction
Another organizes general parameter: i.e. presetting scratch length threshold scope and scratch depth threshold scope, Fig. 9 is rail vehicles car
Module analytic method flow chart is analyzed in the scratch of wheel online scratch automatic checkout system.；
Step 3, analysis primitive curve remove the zone line curve behind head region, territory, tail region, first in this zone line
First find the peak that depth capacity shift value is corresponding, from the beginning of first sampling point position of zone line, be set to initial adopting
Sampling point；；
A, find and the point of starting sample point same depth displacement value by the sampling time sequence of sampled point successively, by the horizontal seat of this point
The abscissa of mark and starting point subtracts each other respectively and obtains the second difference, if the second difference meets default scratch length threshold scope,
The most again the vertical coordinate of the vertical coordinate of peak Yu starting point is subtracted each other and obtain the 3rd difference, when the 3rd difference also meets the wiping preset
Hindering depth threshold scope, the most now wheel is abraded, and obtains abrasive position, the degree of depth, length information；
B, the scratch length threshold scope being unsatisfactory for presetting when the second difference or the 3rd difference are unsatisfactory for the scratch degree of depth preset
During threshold range, then it is repositioned onto the sampled point of subsequent time, is set to new starting point and repeats step A.
Step 4, the abrasive position obtained according to above step, the degree of depth, length information, to rail vehicles wheel
Scratch situation exports and reports to the police.
The head region scope pre-set in described step one on curve is with sampled point as sampling time sequence, before choosing on curve
200 sampled points；Tail regional extent is with sampled point as sampling time sequence, chooses rear 100 sampled points on curve.
The method of the described head region scope pre-set on curve and tail regional extent is: wheel rim and fork detection module
Two end in contact time the curve of beating that can produce when pressing down and leave corresponding fork detection module, reality is crossed car data
Comprehensive analysis forms the interval range that curve of beating occurs, and obtains head region scope and tail regional extent.
