[0002] The suspension gap measurement of high-speed maglev trains is one of the key technologies to ensure stable operation of the trains. The suspension gap refers to the distance between the train and the track, usually about 10mm. In order to achieve accurate suspension gap measurement, a special sensor needs to be used.

In order to reduce the influence of this tooth slot ripple, the current sensor design adopts the measures of three-dimensional coil shape and size optimization, but this also leads to the improvement of the requirements for coil bonding and casting process, resulting in lower sensor yield, higher production cost, limiting the performance and reliability of the suspension system, and also increasing the overall cost of the train.

[0079] The technical solutions in the embodiments of the application will be apparently and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.
[0080] The core of the application is to provide a suspension gap measurement method, device, equipment and medium to solve the problem of gap ripple in the process of measuring the suspension gap of a high-speed maglev train.
[0081] To enable personnel in the technical field to better understand the application scheme, the application will be further described in detail below with reference to the drawings and specific embodiments.
[0082] To solve the problem of gap ripple in the process of measuring the suspension gap of a high-speed maglev train, the application provides a suspension gap measurement method.
[0083] It should be noted that the method provided by the application is applied to a distance measurement system including a first probe group, a second probe group, a back-end processing circuit and a controller. The detection principle of the first probe group and the second probe group is inductive distance measurement, and the probe group is specifically composed of a plurality of coil probes. With the fluctuation of the gap between the electromagnet and the long stator, the probe detects the change of inductance. Secondly, the first probe group and the second probe group are respectively connected with the corresponding back-end processing circuit, and each back-end processing circuit is connected with the controller; the back-end processing circuit obtains the change of inductance value transmitted by the first probe group and the second probe group, obtains the corresponding gap value, and sends the detected gap value to the controller according to the protocol between the controller.
[0084] Figure 1 A schematic diagram of the installation position of the probe group provided by an embodiment of the application. As shown in Figure 1As shown in the drawings, in the present application, the first probe group 7 is arranged on the surface of the electromagnet 6 opposite to the slot structure of the long stator 5, and the second probe group 8 is arranged on the surface of the electromagnet 6 opposite to the tooth structure adjacent to the slot structure of the long stator 5. It should be noted that the specific structure of the first probe group and the second probe group in the present embodiment is not limited, and is determined according to the specific implementation.
[0085] Figure 2 A flow chart of a suspension gap measurement method provided in the present application is shown in the drawings. As shown in the drawings, the method comprises: Figure 2
[0086] S10: obtaining a first gap value measured by the first probe group and a second gap value measured by the second probe group, and selecting a determination mode of the actual gap value.
[0087] S11: when the first determination mode is selected, determining the average value of the first gap value and the second gap value, and determining the average value as the actual gap value.
[0088] S12: when the second determination mode is selected, determining the minimum value of the first gap value and the second gap value, and obtaining a first gap compensation value.
[0089] S13: adding the minimum value and the first gap compensation value to obtain the actual gap value.
[0090] In the specific implementation, first, the first gap value measured by the first probe group and the second gap value measured by the second probe group are obtained. It can be understood that, since the first probe group and the second probe group are arranged at different positions, the gap values measured by the two groups cannot be directly used as the actual gap value. In order to obtain the actual gap value between the long stator and the electromagnet, the determination mode of the actual gap value needs to be selected.
[0091] It should be noted that, in the present embodiment, two determination modes of the actual gap value are provided, and both of the two modes can eliminate the ripple interference in the actual gap value measurement process.
[0092] Specifically, when the first determination mode is selected, the average value of the first gap value and the second gap value is determined, and the average value is determined as the actual gap value. When the second determination mode is selected, the minimum value of the first gap value and the second gap value is determined, and a first gap compensation value is obtained; the minimum value and the first gap compensation value are added to obtain the actual gap value. It should be noted that, in the present embodiment, the specific size of the first gap compensation value is not limited, and is determined according to the specific implementation.
[0093] In addition, there is a feasible way to eliminate the ripple: by constructing a gap ripple processing model, setting the model input as the gap value measured by the first probe group, the gap value measured by the second probe group, and the standard gap between the long stator and the electromagnet, setting the model output as the actual gap value; with the specified ripple as the constraint condition / target value, obtaining sample data through ground test, training the model by using machine learning algorithm (such as extreme gradient boosting algorithm, random forest algorithm, Bayesian statistics, etc.), obtaining the final gap ripple processing model, and applying it to the ranging system.
[0094] In the embodiment, the sensor probes are reasonably arranged according to the gap fluctuation caused by the tooth slot structure of the long stator, and the first probe group and the second probe group form a sensor array. Through the cooperation of multiple probe groups, combined with the two actual gap value measurement methods of gap value averaging and gap value compensation, the ripple existing in the suspension gap measurement can be effectively reduced or even eliminated, and the stability of the suspension control system is improved.

On the basis of the above-mentioned embodiment, in some embodiments, as shown in Figure 3 The first probe group and the second probe group each consist of three probes arranged in parallel along the extension direction of the electromagnet.

[0099] S103: Determine the average value of each gap value in the first probe group, and take the average value of each gap value as the first gap value.
[0100] S104: Confirm that the probe corresponding to the first target gap value is the first faulty probe.
[0101] S105: Mark the first faulty probe and generate alarm information representing the failure of the first faulty probe.
[0102] S106: Obtain the average value of the gap values measured by the remaining probes in the first probe group except the first faulty probe, and take the average value of the remaining gap values in the first probe group as the first gap value.
[0103] To obtain the first gap value, first, gap values measured by each probe in the first probe group are obtained, that is, gap values measured by the three probes are obtained. It is further determined whether there is a first target gap value in each gap value, which has a difference greater than the first threshold value from the remaining gap values. In this embodiment, the size of the first threshold value is not limited, and is determined according to the specific implementation.
[0104] If there is no first target gap value having a difference greater than the first threshold value from the remaining gap values, it is considered that the deviation of the three gap values is within the allowable range, and the average value of each gap value in the first probe group is determined, and the average value of the three gap values is taken as the first gap value.
[0105] If there is a first target gap value having a difference greater than the first threshold value from the remaining gap values, it is considered that the first target gap value measured by one of the three probes deviates significantly compared with the gap values measured by the other two probes, and it is confirmed that the probe corresponding to the first target gap value is the first fault probe. At this time, the first fault probe is marked, and alarm information representing the fault of the first fault probe is generated, so that the staff can maintain the first fault probe according to the mark and the alarm information. The average value of the gap values measured by the remaining probes in the first probe group except the first fault probe is obtained, that is, the average value of the gap values of the remaining two probes is obtained, and the average value of the remaining gap values in the first probe group is taken as the first gap value, thereby improving the accuracy of the first gap value measurement.

[0110] S110: Confirm that the probe corresponding to the second target gap value is the second fault probe.
[0111] S111: Mark the second fault probe, and generate alarm information representing the fault of the second fault probe.
[0112] S112: Obtain the average value of the gap values measured by the remaining probes in the second probe group except the second fault probe, and take the average value of the remaining gap values in the second probe group as the second gap value.
[0113] To obtain the second gap value, first, gap values measured by each probe in the second probe group are obtained, that is, gap values measured by the three probes are obtained. It is further determined whether there is a second target gap value whose difference from the remaining gap values is greater than the first threshold. In this embodiment, the size of the first threshold is not limited, and is determined according to the specific implementation.
[0114] If there is no second target gap value whose difference from the remaining gap values is greater than the first threshold, it is considered that the deviations of the three gap values are within the allowable range, and the average of the gap values in the second probe group is determined, and the average of the three gap values is taken as the second gap value.
[0115] If there is a second target gap value whose difference from the remaining gap values is greater than the first threshold, it is considered that the second target gap value measured by one of the three probes deviates significantly compared with the gap values measured by the other two probes, and it is confirmed that the probe corresponding to the second target gap value is a second fault probe. At this time, the second fault probe is marked, and alarm information representing the fault of the second fault probe is generated, so that the staff can maintain the second fault probe according to the mark and the alarm information. The average of the gap values measured by the remaining probes in the second probe group except the second fault probe is obtained, that is, the average of the gap values of the remaining two probes is obtained, and the average of the remaining gap values in the second probe group is taken as the second gap value, thereby improving the accuracy of measuring the second gap value.
[0116] Figure 4 Another schematic diagram of a probe installation mode provided by the embodiment of the present application is provided. On the basis of the above-mentioned embodiment, in some embodiments, as shown in Figure 4 the first probe group and the second probe group are respectively composed of two probes arranged in parallel along the extension direction of the electromagnet.
[0117] Correspondingly, under the probe installation mode of the above-mentioned first probe group, obtaining the first gap value measured by the first probe group comprises:
[0118] S111: obtaining gap values measured by two probes in the first probe group.
[0119] S112: determining the average of the two gap values in the first probe group, and taking the average of the two gap values as the first gap value.
[0120] To obtain the first gap value, first, gap values measured by two probes in the first probe group are obtained, and the average of the two gap values in the first probe group is further determined, and the average of the two gap values is taken as the first gap value.
[0121] Correspondingly, under the probe installation mode of the above-mentioned second probe group, obtaining the second gap value measured by the second probe group comprises:
[0122] S113: Obtain the gap values measured by the two probes in the second probe group.
[0123] S114: Determine the average of the two gap values in the second probe group, and take the average of the two gap values as the second gap value.
[0124] To obtain the second gap value, first obtain the gap values measured by the two probes in the second probe group, and further determine the average of the two gap values in the second probe group, and take the average of the two gap values as the second gap value.
[0125] On the basis of the above embodiment, in some embodiments, after obtaining the gap values measured by the two probes in the first probe group, further comprising:
[0126] S121: Determine whether the difference between the two gap values is greater than a second threshold value; if not, go to step S112; if greater than the second threshold value, go to step S122.
[0127] S122: Determine the maximum gap value of the two gap values in the first probe group as the third target gap value.
[0128] S123: Determine the minimum gap value of the two gap values in the first probe group as the fourth target gap value.
[0129] S124: Obtain the gap values measured by the two probes in the second probe group.
[0130] S125: According to the gap values measured by the two probes in the second probe group, respectively determine whether the third target gap value and the fourth target gap value are within a first preset range; if the third target gap value is within the first preset range, go to step S126. If the fourth target gap value is within the first preset range, go to step S129.
[0131] S126: Confirm that the probe corresponding to the fourth target gap value has failed.
[0132] S127: Mark the probe corresponding to the fourth target gap value, and generate alarm information representing that the probe corresponding to the fourth target gap value has failed.
[0133] S128: Take the third target gap value as the first gap value.

[0136] S131: take the fourth target gap value as the first gap value.
[0137] In a specific implementation, when the first probe group adopts two probes, the average value of the gap values of the two probes is taken as the first gap value. Once one of the probes fails, the corresponding gap value deviates greatly, which will lead to inaccurate measurement of the first gap value. Therefore, in order to avoid the above situation, after obtaining the gap values measured by the two probes in the first probe group, it is further needed to determine whether the difference between the two gap values is greater than a second threshold. In this embodiment, the size of the second threshold is not limited and is determined according to the specific implementation.
[0138] If the difference is not greater than the second threshold, it is confirmed that the deviation of the gap values measured by the two probes is within the allowable range, and the step of determining the average value of the two gap values in the first probe group is entered to take the average value of the two gap values as the first gap value. If the difference is greater than the second threshold, it is confirmed that the deviation of the gap values measured by the two probes is out of limit, which will lead to inaccurate measurement of the first gap value.
[0139] In order to avoid inaccurate measurement of the first gap value, the maximum gap value of the two gap values in the first probe group is determined as a third target gap value, and the minimum gap value of the two gap values in the first probe group is determined as a fourth target gap value. The gap values measured by the two probes in the second probe group are obtained. The gap values measured by the second probe group are taken as comparison objects, and whether the third target gap value and the fourth target gap value are within a first preset range is determined according to the gap values measured by the two probes in the second probe group. In this embodiment, the first preset range is not limited and needs to be determined according to the gap values measured by the two probes in the second probe group; the gap values within the first preset range are considered to be normal gap values.
[0140] If the third target gap value is within the first preset range, it is considered that the third target gap value is a relatively normal measurement value, and the fourth target gap value is a relatively abnormal measurement value. The third target gap value can be taken as the first gap value. At this time, it is confirmed that the probe corresponding to the fourth target gap value fails; the probe corresponding to the fourth target gap value is further marked, and alarm information indicating that the probe corresponding to the fourth target gap value fails is generated, so that the staff can maintain the probe corresponding to the fourth target gap value according to the mark and the alarm information. If the fourth target gap value is within the first preset range, it is considered that the fourth target gap value is a relatively normal measurement value, and the third target gap value is a relatively abnormal measurement value. The fourth target gap value can be taken as the first gap value. At this time, it is confirmed that the probe corresponding to the third target gap value fails; the probe corresponding to the third target gap value is further marked, and alarm information indicating that the probe corresponding to the third target gap value fails is generated, so that the staff can maintain the probe corresponding to the third target gap value according to the mark and the alarm information. In this way, the accurate measurement of the first gap value is ensured.
[0141] In addition, in the embodiment, the accurate measurement of the first gap value in the case of using two probes in the first probe group is mainly described. It can be understood that the method adopted in the embodiment is also applicable to the measurement of the second gap value in the case of using two probes in the second probe group, so as to ensure the accuracy of the measurement of the second gap value. It should be noted that, unlike the second probe group as the comparison object in the embodiment, when the measurement of the second gap value in the second probe group is performed, the gap value measured by the first probe group is taken as the comparison object, and the specific process is not described herein.
[0142] On the basis of the above-mentioned embodiment, after the first gap value measured by the first probe group and the second gap value measured by the second probe group are obtained, before the determination mode of the actual gap value is selected, the method further comprises:
[0143] S132: Obtain a second gap compensation value.
[0144] S133: Determine whether the difference between the first gap value and the second gap value is greater than a third threshold value; if the difference between the first gap value and the second gap value is greater than the third threshold value, proceed to step S134; if the difference between the first gap value and the second gap value is not greater than the third threshold value, proceed to step S135.
[0145] S134: Add the second gap value and the second gap compensation value to obtain a new first gap value, and proceed to the step of determining the determination mode of the actual gap value;
[0146] S135: judging whether the difference between the second gap value and the first gap value is greater than a third threshold value; if the difference between the second gap value and the first gap value is greater than the third threshold value, entering step S136; if the difference between the second gap value and the first gap value is not greater than the third threshold value, entering the step of selecting the determination mode of the actual gap value.
[0147] S136: adding the first gap value and the second gap compensation value to obtain a new second gap value, and entering the step of selecting the determination mode of the actual gap value.
[0148] In a specific implementation, when the suspended train passes through the beam end joint, the first gap value and the second gap value are far greater than the actual gap value, resulting in a failure of the actual gap value measurement. Therefore, in order to ensure the accurate measurement of the actual gap value, the second gap compensation value is specifically obtained. In this embodiment, the second gap compensation value is not limited and is determined according to a specific implementation.
[0149] Further judging whether the difference between the first gap value and the second gap value is greater than the third threshold value; if the difference between the first gap value and the second gap value is greater than the third threshold value, considering that the first gap value at this time is an error value measured at the joint. In order to avoid the error first gap value leading to a failure of the actual gap value measurement, the second gap value and the second gap compensation value are specifically added to obtain a new first gap value, and the step of selecting the determination mode of the actual gap value is entered for subsequent calculation of the actual gap value.
[0150] If the difference between the first gap value and the second gap value is not greater than the third threshold value, considering that the first gap value at this time is a correct value, further judging whether the difference between the second gap value and the first gap value is greater than the third threshold value; if the difference between the second gap value and the first gap value is greater than the third threshold value, considering that the second gap value at this time is an error value measured at the joint. In order to avoid the error second gap value leading to a failure of the actual gap value measurement, the first gap value and the second gap compensation value are specifically added to obtain a new second gap value, and the step of selecting the determination mode of the actual gap value is entered for subsequent calculation of the actual gap value. If the difference between the second gap value and the first gap value is not greater than the third threshold value, considering that the first gap value and the second gap value are both correct values, entering the step of selecting the determination mode of the actual gap value.
[0151] In this way, it is ensured that the actual gap value measurement is not affected when the train passes through the beam end joint.
[0152] On the basis of the above embodiment, in some embodiments, the method further comprises:
[0153] S14: monitoring the actual gap value according to a preset period and monitoring the current speed of the train.
[0154] S15: determining whether the actual gap value exceeds the second preset range and the current speed of the train is greater than the speed threshold; if yes, proceeding to step S16.
[0155] S16: outputting the warning information.
[0156] In a specific implementation, the actual gap value measured can also be continuously monitored according to a preset period, and the current speed of the train is monitored at the same time. It is further determined whether the actual gap value exceeds the second preset range and the current speed of the train is greater than the speed threshold; in this embodiment, the second preset range and the speed threshold are not limited, and are determined according to the specific implementation.
[0157] If the actual gap value does not exceed the second preset range and / or the current speed of the train is not greater than the speed threshold, the monitoring continues. If the actual gap value exceeds the second preset range and the current speed of the train is greater than the speed threshold, it is considered that the gap is abnormal at the current speed of the train, and the continued operation may have a safety risk, and the warning information needs to be output to prompt the staff to slow down the train and perform inspection.
[0158] In addition, in order to improve the inspection efficiency of the staff, when the actual gap value exceeds the second preset range and the current speed of the train is greater than the speed threshold, the method further includes:
[0159] S17: recording the distance of the current first probe group and the second probe group relative to the long stator.
[0160] S18: generating a measurement log; wherein the measurement log contains the change of the actual gap value in a preset time period before the actual gap value exceeds the second preset range.
[0161] Specifically, in order to improve the inspection efficiency of the staff, it is also necessary to record the distance of the current first probe group and the second probe group relative to the long stator, so as to facilitate the staff to check the abnormal gap value. At the same time, a measurement log is generated; the measurement log contains the change of the actual gap value in a preset time period before the actual gap value exceeds the second preset range, so as to facilitate the staff to check the gap change according to the measurement log.
