Step 103, the accumulation according to each vehicle at the end of the operation information in each sampling period and corresponding sampling period
Abrasion loss obtains the operation information of vehicle and the corresponding relationship of cumulative attrition amount.
In the present embodiment, for each vehicle, operation information of the available vehicle in each sampling period, wherein
Operation information can be such as one of information such as the accumulative operation duration of vehicle, carrying number, temperature, humidity or a variety of.Than
Such as, the operation information of vehicle can be obtained from the control centre of vehicle.In turn, according to each vehicle each sampling period fortune
Row information and the cumulative attrition amount in corresponding sampling period, can establish and store vehicle operation information and cumulative attrition amount it
Between corresponding relationship, for subsequent query use.
Step 104, according to the operation information of vehicle to be assessed, corresponding relationship is inquired, obtains the accumulation mill of vehicle to be assessed
Damage amount.
When needing the wheel wear degree to vehicle to detect, can first obtaining the vehicle, (vehicle is as to be evaluated
Estimate vehicle) operation information by inquiring corresponding relationship, search from the corresponding relationship of storage with vehicle to be assessed in turn
The matched operation information of operation information, and cumulative attrition amount corresponding with the operation information inquired is determined as the vehicle to be assessed
Cumulative attrition amount.Thereby, it is possible to quickly obtain the cumulative attrition amount of vehicle to be assessed, achieve the purpose that real-time detection.
The wheel wear appraisal procedure of the rail traffic vehicles of the present embodiment is read by the sampled point laid by track
Collected wheel clast quality in multiple sampling periods, for each sampling period, according to vehicle collected in the sampling period
It takes turns clast quality and terminates the total degree that each vehicle is run in rail traffic to the sampling period since sampling start time,
Obtain cumulative attrition amount of each vehicle at the end of the sampling period, according to each vehicle each sampling period operation information and
Cumulative attrition amount at the end of the corresponding sampling period, obtains the operation information of vehicle and the corresponding relationship of cumulative attrition amount, according to
The operation information of vehicle to be assessed inquires corresponding relationship, obtains the cumulative attrition amount of vehicle to be assessed.By laying in orbit
Sampled point acquires wheel clast quality, and then the tired of each vehicle is determined according to the wheel clast quality read from sampled point

Flow diagram.
As shown in Fig. 2, step 101 may comprise steps of on the basis of embodiment as shown in Figure 1:
Step 201, for each sampling period in multiple sampling periods, from the corresponding sampled point difference in each station
Read sample magnitude.
It, can be one by one when server reads the wheel clast quality in multiple sampling periods from sampled point in the present embodiment
Sampling period is successively read.At the time of reading, for each sampling period in multiple sampling periods, server can be from each vehicle
Corresponding sampled point of standing reads sample magnitude respectively；Alternatively, server can be successively read sample magnitude by sampled point one by one, for
Each sampled point, server read the sample magnitude in each sampling period of sampled point acquisition, then for multiple sampling weeks
Interim each sampling period counts the sample magnitude of each sampled point acquisition in the sampling period.Wherein, sample magnitude is
The quality for the wheel clast collected at sampled point.
In a kind of possible implementation of the embodiment of the present invention, sample magnitude can be sampled point obtained from measurement it is mixed
It closes in amount of substance and subtracts what the dust quality that same position measurement obtains obtained, wherein mixture includes wheel clast and dust.
In order to avoid the dust in air is to the interference using numerical value, the side installation one for the acquisition equipment that can be installed at sampled point
The acquisition device of a quality for being exclusively used in acquisition air nature dust, for that can set the ID of acquisition device to convenient for distinguishing
It is consistent with the ID of acquisition equipment of same sampled point, then the quality that device measuring is acquired at sampled point is subtracted to the acquisition of identical ID
Resulting difference is as sample magnitude after the dust quality of device acquisition.
In a kind of possible implementation of the embodiment of the present invention, for the accuracy and reasonability for guaranteeing sample magnitude, go back
Sample magnitude can be screened.Due to being incremented by with the time, the sample magnitude of same sampled point acquisition can be with the time
Increase and become larger or constant, without becoming smaller.Therefore, in the present embodiment, if being directed to same sampled point, this sampling
The sample magnitude read in period is less than the sampling point value read in a upper period, then shows the sample magnitude this time acquired
It is wrong, the sample magnitude read in this sampling period of sampled point is abandoned, and using average value as sampled point this sampling week
The sample magnitude read in phase.Wherein, average value is that the sample magnitude in this sampling period retained is averaging.Herein
It should be noted that the sample magnitude in this sampling period retained is not less than the sampling number read in a upper sampling period
Value.
Step 202, it sums to the sample magnitude read, obtains acquisition in each sampling period in multiple sampling periods
The wheel clast quality arrived.
In the present embodiment, for each sampling period in multiple sampling periods, server is corresponding from each station
It after sampled point reads sample magnitude, can sum to the sample magnitude read, obtain acquisition in the sampling period
Wheel clast quality.That is, sum to the sample magnitude for the different sampled points for belonging to the same sampling period, gained
It as a result is the wheel clast quality in the sampling period.
The wheel wear appraisal procedure of the rail traffic vehicles of the present embodiment, by for each in multiple sampling periods
Sampling period reads sample magnitude from the corresponding sampled point in each station respectively, sums, obtains to the sample magnitude read
Collected wheel clast quality in each sampling period into multiple sampling periods, can accurately obtain each sampling period

Output of the cumulative attrition amount as machine learning model in this, is trained machine learning model, then the machine after training
Learning model can be used for expressing the corresponding relationship between vehicle operating information and cumulative attrition amount, input the operation letter of vehicle
Breath, can obtain corresponding cumulative attrition amount.
Step 307, operation information of the vehicle to be assessed within the period to be assessed is obtained.
Step 308, the operation information according to vehicle to be assessed within the period to be assessed, inquire corresponding relationship, obtain to
Assess the cumulative attrition amount of wheel in the period.
In the present embodiment, when needing to carry out wheel wear detection to vehicle to be assessed, available vehicle to be assessed exists
Operation information in period to be assessed.For example, needing to complete vehicle to be assessed the abrasion feelings of wheel until the last operation
Condition is detected, then when bringing into operation that this period is to be assessed until completing the last operation from vehicle to be assessed
Section, the operation informations such as average passenger occupancy, operation duration, the number of run of available vehicle to be assessed within the period to be assessed,
And then according to the operation information of acquisition, by inquiring corresponding relationship, available vehicle to be assessed wheel within the period to be assessed
