Description
Technical Field

Background
The current operation EMUs vehicle all has the preventative protection demand to the wheel footpath deviation, leads to train traction transmission system operation trouble because of the wheel footpath deviation is too big in order to avoid the train operation process. In the long-term operation of the motor train unit, the wheel diameters of the power shaft wheels are different due to various losses such as wheel-rail friction and rotary wheels, and the possibility of errors, inaccuracy or real-time updating exists because the reference wheel diameter acquired by the controller is set and transmitted by the vehicle-mounted network control system in the current vehicle operation. When the traction converter controls the motor to apply force, the actual exertion force of each wheel pair is inconsistent, and the service life of the train wheel pair and the normal operation of the traction converter are further influenced.
The prior technical scheme is as follows:
if the wheel diameter calibration condition of the rail transit train is met, respectively obtaining the wheel diameter error tolerance value increase amplitude of the rail transit train during slipping and idling; obtaining the actual running distance of the wheel slipping train and the corresponding accumulated pulse number; acquiring the actual walking accumulated pulse number of the wheel idling train and the actual distance between the corresponding transponder pairs; calculating a train wheel diameter value according to the fixed pulse number of each period of the speed sensor and the actual distance of the transponder, if the absolute value of the difference between the train wheel diameter value obtained by the calculation in the current round and the wheel diameter value of the last round of calibration train wheel diameter value is smaller than the wheel diameter error tolerance value, successfully calibrating the wheel diameter, otherwise, considering that the calibration fails; if the calibration is successful, the train wheel diameter value is the arithmetic mean of the train wheel diameter value obtained by the calculation of the current round and the wheel diameter value of the last round of calibration; if the calibration fails, the wheel diameter is recalibrated by repeating the steps.
Yet another method, comprising the steps of: (1) firstly, determining an initial value of the train wheel diameter; (2) arranging transponders, selecting two adjacent transponders on a straight line as a reference standard for wheel diameter correction, and measuring the actual distance between the two transponders; (3) the train obtains the running distance in the appointed time according to the measured speed, and the wheel diameter updating value can be obtained according to the ratio of the running distance to the measured actual distance and the wheel diameter initial value; (4) checking the validity of the wheel diameter updating value; (5) and carrying out bad value filtering processing on the updated value of the train wheel diameter. The invention utilizes the transponder system of the subway line standard distribution as the auxiliary equipment for automatically correcting the train wheel diameter, realizes the automatic wheel diameter correction of the train and simultaneously improves the accuracy of speed measurement and positioning of the system.
However, the above solutions have the following disadvantages:
1) the wheel diameter correction needs to manually set a reference wheel diameter value, and if the reference wheel diameter value is set wrongly, the conventional method cannot identify source errors, so that the wheel diameter correction result is wrong, and the real wheel diameter cannot be correctly reflected;
2) when the running conditions of the motor train unit are different, the speed of a reference shaft selected by wheel diameter correction is distorted due to speed change deviation caused by traction and braking, speed mutation caused by idling, sliding and the like, which may exist, and the correction result based on the speed is not credible;
3) the additional increase of related testing equipment such as speed, distance and the like causes cost increase and low cost performance.
Therefore, a method for checking the wheel diameter deviation by considering the working condition and avoiding artificially setting the reference wheel diameter value is needed.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a method for calculating a train wheel diameter deviation according to an embodiment of the present application, and a specific technical solution is as follows:
s101: when the driver controller is in a zero position, selecting a set speed as a reference speed, and determining the shaft speed cumulant according to the reference speed;
it is first noted that the train may not detect wheel diameter deviations in any case. Certain working conditions need to be met, and the wheel diameter deviation detected under different working conditions can cause detection result distortion due to traction or braking. The application therefore emphasizes the detection of the wheel diameter deviation of the train under specific working conditions.
When the train is in a zero position, the train wheel does not actively apply force, and the wheel diameter deviation is preferably detected. Of course, but not limited to, the following conditions may also be included:
1) the controller detects that the speed sensor is in a normal state;
2) the controller detects that the running state of the wheel set is normal and has no speed mutation;
3) the controller does not output a torque command;
4) and the comprehensive reference speed of the motor train unit is greater than a set value.
When the conditions are met, the distortion rate of the detected wheel diameter deviation value is extremely small, and the reliability is high. The comprehensive reference speed of the motor train unit needs to be larger than a set value, and the signal is not stable enough at low speed and is not accurate enough naturally.
And selecting a set speed as a reference speed under the condition that the train state condition is met. For example, referring to fig. 2, fig. 2 is a schematic diagram of a data transmission structure of a train network control system and a DCU. The DCU (drive Control Unit) is a transmission Control unit and is used for an alternating-current transmission locomotive, the train in the figure is a power-dispersed motor train unit, a power car drives wheel sets to move through a traction motor, a bogie, a wheel shaft joint and the like, and a power car controller collects pulse signals of a wheel set speed encoder through a speed sensor and decodes the pulse signals into speed signals. The reference speed may therefore be a speed signal collected by the speed sensor.
It is worth mentioning that the selected reference speed needs to be an effective speed, and for the purposes of this application, an effective speed refers to a speed that can be used as a reference for calculating the deviation of the train wheel diameter. Therefore, before this step, there may also be a step of selecting an effective speed:
and obtaining effective shaft speed cumulant according to the principle that the effective accumulative displacement is the same, and deleting ineffective shaft speed. Eliminating invalid shaft speeds is a conventional technical means and will not be explained here.
According to the principle, the motor train unit is assumed as a whole with hard connection, and the effective accumulated displacement of each element in the motor train unit moving along with the motor train unit is obtained in the same way:
wherein the content of the first and second substances,
to effectively accumulate the displacement, TnFor the acquisition frequency of the velocity, V and VnIn order to judge the obtained effective speed according to the real-time acquisition speed, the effective shaft speed cumulant can be obtained according to the formula.
Any shaft speed signal can be selected as a reference speed, and the effectiveness of other shaft speeds can be judged. When the other shaft speeds are all valid, the shaft speed is considered to be the reference speed. At which time resynchronization accumulates all other shaft speeds.
In addition to the shaft speed, a speed that can be used as a reference speed, such as a vehicle central control system reference speed, a driven vehicle speed, or the like, may be selected.
S102: calculating the wheel diameter deviation of each shaft iteratively according to a wheel diameter deviation calculation formula;
the wheel diameter deviation calculation formula refers to:
in the formula (I), the compound is shown in the specification,
is a reference wheel diameter value, DsetIs the reference diameter of the shaft wheel DdifIs the deviation of the wheel diameter, and the wheel diameter,
is the actual wheel diameter value.
A preset value can be set for the number of iterations, the calculation is stopped after the preset value is reached, and the "determining the effective wheel diameter deviation" and the subsequent steps in S103 are directly performed.
It should be noted that the present application refers to wheel diameter values
The setting mode of (2) is not limited, and the reference wheel diameter value can be obtained on line, and the vehicle can be used for setting the reference wheel diameter value, namely the reference wheel diameter value is not required to be obtained from the outside of the vehicle.
S103: and when the accumulated amount of the shaft speed reaches a limiting value, determining the effective wheel diameter deviation, and calculating the average value of the effective wheel diameter deviation of each shaft to serve as the final wheel diameter deviation of each shaft.
Whether the calculated wheel diameter deviation is valid or not can be obtained by comparing the calculated wheel diameter deviation with a threshold value, and the setting mode of the threshold value is not limited herein. Preferably, the wheel diameter deviation obtained by calculation is compared according to the design parameters of the vehicle wheel set, and whether the wheel diameter deviation is effective or not is judged. If valid, the average is then calculated as the final wheel-set deviation for that axle.
And for invalid data, judging the invalid reason or judging whether the corresponding shaft speed data source is normal according to the number of the invalid data, and further carrying out subsequent overhaul and maintenance work.
In S101, it is mentioned that other shaft speeds are synchronously accumulated, and when the shaft speed accumulation reaches the amplitude limit value, it means that the process of this shaft speed accumulation is finished, and at this time, each shaft speed accumulation value is latched. It is worth mentioning that the process of shaft speed accumulation can be selected to be ended when any shaft speed accumulation reaches the limit value. Any limitation on the setting mode of the clipping value and the specific magnitude should be set by those skilled in the art according to the actual situation.
It will be appreciated that appropriate protective measures may also be taken once a large wheel diameter deviation is detected.
After each verification, corresponding wheel diameter deviation value zero clearing operation can be executed to prepare for next wheel diameter deviation verification.
The embodiment of the application provides a method for detecting the wheel diameter deviation of a train, which can select a set effective speed as a reference under the conditions of determining the speed effectiveness and specific working conditions and directly calculate the difference between the wheel diameter of each shaft and a reference shaft through a formula. The error caused by manual setting is avoided, the amplitude limiting value can be freely adjusted, and the wheel diameter deviation can be calculated more conveniently, simply and rapidly.
