[0059] The embodiments of the present invention provide a skid braking control method, device, electronic device and computer-readable storage medium for a maglev train, which can reduce the situation of excessive heat capacity to a certain extent, thereby reducing the skid's requirements for heat capacity indicators, and can select more economical skid materials, which is conducive to reducing the overall cost of the vehicle.

[0060] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] Please refer to Figure 1 , Figure 1 A schematic flow chart of a skid brake control method for a maglev train provided by an embodiment of the present invention. The skid brake control method for a maglev train comprises:

[0062] S110: when the train is in the process of skid braking, obtaining the actual braking force of the train;

[0063] It should be noted that, in the embodiment of the present invention, when a sled braking signal is detected, sled braking can be controlled to be applied to a car of the train, specifically, sled braking can be applied to the first car. When the train is in the sled braking process, the current actual braking force of the train can be obtained in real time or periodically.

[0064] S120: Determine whether the actual braking force meets the braking force requirement;

[0065] Specifically, after obtaining the current actual braking force of the train, it can be further determined whether the actual braking force meets the current braking force requirement of the train, wherein the braking force requirement can be determined based on the braking force required by the entire vehicle of the train, that is, the braking force required by the entire vehicle can be obtained, and the actual braking force can be compared with the braking force required by the entire vehicle, and whether the actual braking force meets the braking force requirement can be determined by determining whether the actual braking force reaches the braking force required by the entire vehicle.

[0066] S130: When the actual braking force does not meet the braking force requirement, a car to be braked is determined from among the cars to which the sled brake has not been applied;

[0067] It should be noted that, when the actual braking force does not meet the braking force requirement, that is, when the actual braking force does not reach the braking force required by the entire vehicle, it means that the braking force of the current sled brake of the train cannot meet the braking force requirement of the train. At this time, a car can be determined from the cars of the train that have not applied the sled brake as the car to be applied, and a car seat to be applied can be arbitrarily selected from the cars that have not applied the sled brake, or a car located after the last car to which the sled brake has been applied from the cars that have not applied the sled brake can be used as the car to be applied.

[0068] S140: Apply skid brakes to the vehicle to be braked.

[0069] Specifically, after determining the vehicle to be applied, the sled brake can be applied to the vehicle to be applied. In actual application, the sled brake application instruction can be sent to the vehicle to be applied. After receiving the sled brake application instruction, the vehicle to be applied executes the sled brake according to the sled brake application instruction, that is, lowers the corresponding sled to apply the sled brake to the vehicle.

[0070] It can be seen that in the embodiment of the present invention, when the train is in the sled braking process, the current actual braking force of the train is obtained, and then it is determined whether the actual braking force meets the braking force requirement of the train. If the braking force requirement is not met, a car to be braked is determined from the cars of the train that have not applied the sled braking, and then the sled braking is applied to the car to be braked. In the present application, when the sled braking of the train is performed, the sled braking is not applied to each car at the same time, but the sled braking force of one car is increased when the actual braking force of the train does not meet the braking force requirement, so as to avoid continuous friction of all cars and reduce the situation of excessive heat capacity to a certain extent, thereby reducing the requirements of the sled on the heat capacity index, and a more economical sled material can be selected, which is conducive to reducing the overall cost of the vehicle.

[0071] Based on the above examples, please refer to Figure 2 and Figure 3 The embodiments of the present invention will further illustrate and introduce the technical solution:

[0072] S210: when the train is in the process of skid braking, obtaining the actual braking force of the train;

[0073] S220: Determine whether the actual braking force meets the braking force requirement;

[0074] Specifically, after obtaining the current actual braking force of the train, it is possible to further determine whether the actual braking force meets the current braking force requirements listed, wherein the braking force requirements can be determined based on the braking force required for the entire vehicle. That is, the braking force required for the entire vehicle can be obtained, and the actual braking force can be compared with the braking force required for the entire vehicle. By determining whether the actual braking force reaches the braking force required for the entire vehicle, it is determined whether the actual braking force meets the braking force requirements.

[0075] Furthermore, the process of determining whether the actual braking force meets the braking force requirement in S220 may specifically include:

[0076] Obtain the braking force required for the entire train;

[0077] Determine whether the actual braking force reaches the braking force required by the vehicle;

[0078] When the actual braking force reaches the braking force required by the vehicle, the actual braking force meets the braking force requirement;

[0079] When the actual braking force is lower than the braking force required by the entire vehicle, the actual braking force does not meet the braking force requirement.

[0080] It should be noted that after obtaining the current actual braking force of the train, the current braking force required by the entire vehicle of the train can also be obtained, and it can be further determined whether the actual braking force reaches the braking force required by the entire vehicle. Specifically, the actual braking force can be compared with the braking force required by the entire vehicle to determine whether the actual braking force reaches (that is, is greater than or equal to) the braking force required by the entire vehicle. If the actual braking force is greater than or equal to the braking force required by the entire vehicle, it means that the current braking force meets the braking force requirement. If the applied braking force is lower than (that is, less than) the braking force required by the entire vehicle, it means that the current braking force does not meet the braking force requirement.

[0081] Furthermore, the process of obtaining the braking force required by the entire train may include:

[0082] Get the current train speed information and train load;

[0083] Determine the train's position information based on the speed information and the train's speed-position curve;

[0084] Calculate the required braking force of the train according to the speed information, position information and train load;

[0085] Specifically, the current required acceleration of the train can be obtained according to the speed information and the position information combined with the first calculation relationship;

[0086] According to the required acceleration of the whole vehicle and the train load combined with the second calculation relationship, the required braking force of the whole vehicle of the train is obtained; wherein:

[0087] The first calculation relationship is ;

[0088] The second calculation relationship is: ;

[0089] in, represents the required acceleration of the vehicle, represents the speed at time t1, represents the speed at time t2, represents the position at time t1, represents the position at time t2, It represents the braking force required for the whole vehicle, and M represents the train load.

[0090] Furthermore, the process of obtaining the actual braking force of the train may include:

[0091] The actual braking force of the train is calculated based on the speed information and train load.

[0092] Specifically, the actual braking force of the train can be obtained according to the speed information and the train load combined with the third calculation formula; wherein:

[0093] The third relation is: , Indicates the actual braking force of the train.

[0094] It should be noted that the specific implementation process of S120 in the above embodiment may also be the implementation process of S220 in the embodiment of the present invention.

[0095] S230: When the actual braking force does not meet the braking force requirement, a car to be braked is determined from among the cars to which the sled brake has not been applied;

[0096] S240: Apply skid brakes to the vehicle to be braked.

[0097] It should be noted that S210 to S240 in the embodiment of the present invention correspond to S110 to S140 in the above embodiment. Therefore, for the introduction of S210 to S240 involved in the embodiment of the present invention, reference can be made to S110 to S140 in the above embodiment, and the embodiment of the present invention will not be repeated here.

[0098] S250: When the actual braking force meets the braking force requirement, obtaining the sled brake application time of each car currently having sled brake applied;

[0099] It should be noted that when the actual braking force meets the braking force requirement, that is, when the actual braking force reaches the braking force required by the entire vehicle, it means that the braking force of the current sled brake of the train can meet the braking force requirement of the train, and at this time, the sled brake application time corresponding to each vehicle of the train that has applied the sled brake can be obtained. In actual application, the timing can be started when the sled brake is applied to the vehicle, so as to obtain the sled brake application time corresponding to the vehicle from the beginning of applying the sled brake to the current moment.

[0100] S260: Determine, based on the sled brake application time of each car currently subjected to sled brake application and the preset thermal capacity limit time, a target sled brake-applied car whose sled brake application time reaches the preset thermal capacity limit time;

[0101] Specifically, in order to avoid the sled thermal capacity being too large due to the long duration of the sled braking applied by the vehicle, the sled thermal capacity limit duration can be predetermined, which can be determined by experiments or empirical values. That is, when the duration of the sled braking is not greater than the sled thermal capacity limit duration, the sled will not fail due to excessive thermal capacity. If the duration of the sled braking is greater than the sled thermal capacity limit duration, the sled may fail due to excessive thermal capacity. Therefore, in the embodiment of the present invention, the size of the preset thermal capacity limit duration can be predetermined, and then, when the actual braking force of the train meets the braking force requirement, the sled braking application duration of each car currently having the sled brake applied is compared with the preset thermal capacity limit duration. If there is a sled brake applied car whose sled braking application duration is greater than the preset thermal capacity limit duration, the car is determined as the target sled brake applied car A.

[0102] S270: Determine whether there is a car in each car section that has not applied the sled brake. If yes, proceed to S280;

[0103] It should be noted that, in the case where there is a car with applied sled brake whose sled brake application time is longer than the preset thermal capacity limit time, in order to further ensure the braking force required by the whole car, it is necessary to determine a car without applied sled brake from all cars in the train that have not applied sled brake to replace the determined target car A with applied sled brake. In the embodiment of the present invention, it can be determined first whether there is still a car without applied sled brake among the cars in the train.

[0104] S280: Determine a target non-application vehicle from among the vehicles to which the skid brake is not applied;

[0105] It can be understood that, when it is determined that there is a car in each car section that does not apply the sled brake, one car is determined as the target car B from among the cars in which the sled brake is not applied.

[0106] S290: Cancel the sled brake of the target vehicle that has applied the sled brake, and apply the sled brake to the target vehicle that has not applied the sled brake.

[0107] Specifically, after determining that the target vehicle A has not been applied, the sled brake of the target vehicle A with sled brake applied and the sled brake application time determined above to be greater than the preset thermal capacity limit time can be revoked, and at the same time, the sled brake is applied to the target vehicle B without being applied, so that the sled of the target vehicle with sled brake applied and the sled brake application time greater than the preset thermal capacity limit time can get a rest while ensuring that the braking force of the train meets the braking force required by the entire vehicle. That is, the present application can avoid friction and excessive heat capacity caused by continuous friction of a single vehicle sled by adjusting the number of sled descents of the entire vehicle, the timing of sled descent, the number of resets and the timing of resets, thereby ensuring the performance of the sled and reducing the requirements of the sled on the thermal capacity index, thereby selecting more economical sled materials and reducing costs.

[0108] The present invention also provides a corresponding device for the sled brake control method of a maglev train, which further makes the method more practical. Among them, the device can be described from the perspective of functional modules and hardware.
