Description

Technical Field

[0001] The present application relates to the technical field of maglev technology, and particularly relates to an electromagnet control method, system, device, maglev train and readable storage medium. Background Art

[0002] The high-speed maglev train realizes the redundancy of the suspension system through a lap joint structure. Each suspension lap joint module includes two sets of single-point suspension systems. When any one system fails, the adjacent electromagnet can bear the corresponding load to ensure the driving safety of the high-speed maglev train. However, in practical applications, due to factors such as the installation accuracy of the gap sensor and the installation accuracy of the electromagnet, there will be a static error in gap measurement, resulting in different current magnitudes of the two electromagnets of the lap joint structure during normal operation, and even a phenomenon that the weight of the lap joint structure is mainly borne by one electromagnet, thus causing the current of a single electromagnet to be too large and the temperature rise to be obvious, which is not conducive to the long-term operation of the high-speed maglev train.

[0055] The core of the present application is to provide an electromagnet control method, system, device, maglev train and readable storage medium, so that the lap joint structure reaches current balance, solve the problem that the current of a single electromagnet is too large and the heat generation is obvious, which is beneficial to the long-term operation of the maglev train.

[0056] To make the objectives, 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. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0057] In the first aspect, please refer toFigure 1 , Figure 1 is a flowchart of the steps of an electromagnet control method provided by this application. The electromagnet control method includes:

[0058] S101: Obtain the first current of the first electromagnet and the second current of the second electromagnet corresponding to the lap joint structure of the maglev train. Among them, the first electromagnet and the controller are in the same single-point suspension system, and the second electromagnet and the controller are in different single-point suspension systems;

[0059] Specifically, the maglev train realizes the redundancy of the suspension system through the lap joint structure. Each lap joint module includes two sets of single-point suspension systems. The first electromagnet and the second electromagnet in this step are respectively the electromagnets on both sides of the lap joint structure. Each electromagnet corresponds to a controller. The solution of this embodiment is applied to the controller in each single-point suspension system. The first electromagnet in this step is the electromagnet in the same single-point suspension system as the controller, and the second electromagnet is the electromagnet in the adjacent single-point suspension system. For example, assume that controller A and electromagnet A are in the same single-point suspension system, and controller B and electromagnet B are in the same single-point suspension system. The two single-point suspension systems form a lap joint module. When controller A executes the operations of S101 - S103, the first electromagnet is electromagnet A, and the second electromagnet is electromagnet B. When controller B executes the operations of S101 - S103, the first electromagnet is electromagnet B, and the second electromagnet is electromagnet A.

[0060] Specifically, obtain the first current of the first electromagnet and obtain the second current of the second electromagnet. Here, the first current can be the average value of multiple currents of the first electromagnet obtained within a preset time period. Correspondingly, the second current is the average value of multiple currents of the second electromagnet obtained within the same time period.

[0061] S102: Judge whether the lap joint structure meets the current balance condition based on the first current and the second current. If not, execute S103;

[0062] As an optional embodiment, the process of judging whether the lap joint structure meets the current balance condition based on the first current and the second current includes:

[0063] Calculate the deviation value between the first current and the second current;

[0064] Judge whether the absolute value of the deviation value is less than the deviation preset value;

[0065] If not, determine that the lap joint structure does not meet the current balance condition;

[0066] If so, determine that the lap joint structure meets the current balance condition.

[0067] Specifically, it can be determined whether the lap joint structure meets the current balance condition according to the magnitudes of the first current and the second current. For example, the deviation value between the first current and the second current can be calculated. If the absolute value of the deviation value is less than the preset deviation value, it indicates that the current of the lap joint structure is balanced. If the absolute value of the deviation value is not less than the preset deviation value, it indicates that the lap joint structure does not meet the current balance condition.

[0068] Of course, in addition to judging whether the lap joint structure meets the current balance condition according to the above scheme, it can also be judged by other means, which is not specifically limited in this embodiment.

[0069] S103: Adjust the suspension gap of the first electromagnet and / or the second electromagnet so that the lap joint structure meets the current balance condition.

[0070] Specifically, considering that the current of the first electromagnet and / or the second electromagnet can be adjusted by adjusting the suspension gap of the first electromagnet and / or the second electromagnet, therefore, the size of the suspension gap of the electromagnet can be adjusted according to the magnitude relationship between the first current and the second current. For example, if the first current is greater than the second current, the suspension gap of the first electromagnet can be increased to reduce the current of the first electromagnet, and at the same time, the suspension gap of the second electromagnet can be reduced to increase the current of the second electromagnet, so that the currents of the first electromagnet and the second electromagnet reach balance, and further make the lap joint structure meet the current balance condition.

[0071] It can be seen that in this embodiment, the current balance state of the lap joint structure is determined according to the magnitudes of the currents of the two electromagnets in the maglev train lap joint structure. If the current of the lap joint structure is unbalanced, the suspension gap of the first electromagnet and / or the second electromagnet in the lap joint structure is adjusted, so as to adjust the current of the first electromagnet and / or the second electromagnet, making the lap joint structure reach current balance, solving the problem that the current of a single electromagnet is too large and the heat generation is obvious, which is beneficial to the long-term operation of the maglev train.

[0072] Based on the above embodiment:

[0073] As an optional embodiment, the process of adjusting the suspension gap of the first electromagnet and / or the second electromagnet includes:

[0074] When the deviation value is greater than the preset deviation value, and the current target suspension gap of the first electromagnet is less than the first preset threshold, increase the target suspension gap of the first electromagnet to make the deviation value decrease;

[0075] When the deviation value is less than or equal to the preset deviation value, and the current target suspension gap of the first electromagnet is greater than the second preset threshold, decrease the target suspension gap of the first electromagnet to make the deviation value decrease;

[0076] Wherein, the first preset threshold is greater than the second preset threshold.

[0077] Specifically, the control scheme of controller A will be described first. For controller A, the first electromagnet corresponding to controller A is electromagnet A, and the second electromagnet is electromagnet B. Correspondingly, the first current is the current \(I_A\) of electromagnet A, and the second current is the current \(I_B\) of electromagnet B. For controller B, the first electromagnet corresponding to controller B is electromagnet B, and the second electromagnet is electromagnet A. Correspondingly, the first current is the current \(I_B\) of electromagnet B, and the second current is the current \(I_A\) of electromagnet A.

[0078] For example, if the current of electromagnet A is greater than the current of electromagnet B:

[0079] Then for controller A, the deviation value \((I_A - I_B)\) of the first current and the second current it obtains will be greater than the deviation preset value. At the same time, for controller B, the deviation value \((I_B - I_A)\) of the first current and the second current it obtains will be less than or equal to the deviation preset value.

[0080] Similarly, if the current of electromagnet A is less than the current of electromagnet B:

[0081] Then for controller A, the deviation value \((I_A - I_B)\) of the first current and the second current it obtains will be less than or equal to the deviation preset value. For controller B, the deviation value \((I_B - I_A)\) of the first current and the second current it obtains will be greater than the deviation preset value.

[0082] On this basis, controller A and controller B can adjust the target suspension gap of the electromagnet in their respective single-point suspension systems according to the first current and the second current they obtain.

[0083] Still taking the above example for illustration, if the current of electromagnet A is greater than the current of electromagnet B:

[0084] For controller A, it can determine that the deviation value \((I_A - I_B)\) of the first current and the second current is greater than the deviation preset value. Then controller A judges the current cycle. Whether the current target suspension gap of the first electromagnet (i.e., electromagnet A) corresponding to its single-point suspension system is less than the first preset threshold. If not, the target suspension gap of electromagnet A is not adjusted in the current cycle. If so, the target suspension gap of electromagnet A is increased in the current cycle, thereby reducing the current of electromagnet A, so that the deviation value of the current of electromagnet A and the current of electromagnet B is reduced, so as to make the lap joint structure reach current balance.

[0085] Meanwhile, for Controller B, it can determine that the deviation value between the first current and the second current (I_B - I_A) is less than or equal to the preset deviation value. Then, Controller B determines whether the current target suspension gap of the first electromagnet (i.e., Electromagnet B) corresponding to the single-point suspension system it belongs to in the current cycle is greater than the second preset threshold. If not, the target suspension gap of Electromagnet B is not adjusted in the current cycle. If so, the target suspension gap of Electromagnet B is reduced, thereby increasing the current of Electromagnet B, reducing the deviation value between the current of Electromagnet B and the current of Electromagnet A, and enabling the lap joint structure to achieve current balance.

[0086] If the current of Electromagnet A is less than the current of Electromagnet B:

[0087] For Controller A, it can determine that the deviation value between the first current and the second current (I_A - I_B) is less than or equal to the preset deviation value. Then, Controller A determines whether the current target suspension gap of the first electromagnet (i.e., Electromagnet A) corresponding to the single-point suspension system it belongs to in the current cycle is greater than the second preset threshold. If not, the target suspension gap of Electromagnet A is not adjusted in the current cycle. If so, the target suspension gap of Electromagnet A is reduced in the current cycle, thereby increasing the current of Electromagnet A, reducing the deviation value between the current of Electromagnet A and the current of Electromagnet B, and enabling the lap joint structure to achieve current balance;

[0088] Meanwhile, for Controller B, it can determine that the deviation value between the first current and the second current (I_B - I_A) is greater than the preset deviation value. Then, Controller B determines whether the current target suspension gap of the first electromagnet (i.e., Electromagnet B) corresponding to the system it belongs to in the current cycle is less than the first preset threshold. If not, the target suspension gap of Electromagnet B is not adjusted in the current cycle. If so, the target suspension gap of Electromagnet B is increased, thereby reducing the current of Electromagnet B, reducing the deviation value between the current of Electromagnet B and the current of Electromagnet A, and enabling the lap joint structure to achieve current balance.

[0089] As an alternative embodiment, the process of increasing the target suspension gap of the first electromagnet includes:

[0090] Increasing the target suspension gap of the first electromagnet by the first preset step size;

[0091] Correspondingly, the process of reducing the target suspension gap of the first electromagnet includes:

[0092] Reducing the target suspension gap of the first electromagnet by the second preset step size.

[0093] As an alternative embodiment, to avoid overshoot, in this embodiment, the suspension gap of the electromagnet is adjusted according to a preset step size. Specifically, in the current cycle, the current target suspension gap is increased by the first preset step size Δs1, or reducing the current target suspension gap by a second preset step Δs2 , Δs1 and Δs2 The values can be set according to actual needs, and the present application does not make specific limitations here.

[0094] In summary, when the current of the electromagnet A is greater than the current of the electromagnet B, the suspension gap of the electromagnet A is increased while the suspension gap of the electromagnet B is decreased to reduce the current of the electromagnet A and increase the current of the electromagnet B at the same time to achieve balance between the two; when the current of the electromagnet A is less than the current of the electromagnet B, the suspension gap of the electromagnet A is decreased while the suspension gap of the electromagnet B is increased to increase the current of the electromagnet A and decrease the current of the electromagnet B at the same time to achieve balance between the two.

[0095] As an optional embodiment, the process of adjusting the suspension gap of the first electromagnet and / or the second electromagnet includes:

[0096] Determine the adjustment priorities of the first electromagnet and the second electromagnet;

[0097] If the adjustment priority of the first electromagnet is greater than that of the second electromagnet and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, adjust the target suspension gap of the first electromagnet until the lap joint structure meets the current balance condition. If the lap joint structure does not meet the current balance condition after the target suspension gap reaches its corresponding preset threshold, generate a trigger signal and no longer adjust the target suspension gap of the first electromagnet;

[0098] If the adjustment priority of the first electromagnet is less than that of the second electromagnet, when a trigger signal is received and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, adjust the target suspension gap of the first electromagnet until the lap joint structure meets the current balance condition.

[0099] As an optional embodiment, when the first current is greater than the second current, if the adjustment priority of the first electromagnet is greater than that of the second electromagnet and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, the process of adjusting the target suspension gap of the first electromagnet includes:

[0100] If the adjustment priority of the first electromagnet is greater than that of the second electromagnet and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, increase the target suspension gap of the first electromagnet;

[0101] Correspondingly, if the adjustment priority of the first electromagnet is less than that of the second electromagnet, when a trigger signal is received and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, the process of adjusting the target suspension gap of the first electromagnet includes:

[0102] If the adjustment priority of the first electromagnet is less than that of the second electromagnet, when a trigger signal is received and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, the target suspension gap of the first electromagnet is decreased.

[0103] As an alternative embodiment, the process of increasing the target suspension gap of the first electromagnet includes:

[0104] Increasing the target suspension gap of the first electromagnet by a third preset step size;

[0105] Correspondingly, the process of decreasing the target suspension gap of the first electromagnet includes:

[0106] Decreasing the target suspension gap of the first electromagnet by a fourth preset step size.

[0107] As an alternative embodiment, when the first current is less than the second current, if the adjustment priority of the first electromagnet is greater than that of the second electromagnet and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, the process of adjusting the target suspension gap of the first electromagnet includes:

[0108] If the adjustment priority of the first electromagnet is greater than that of the second electromagnet and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, decreasing the target suspension gap of the first electromagnet;

[0109] Correspondingly, if the adjustment priority of the first electromagnet is less than that of the second electromagnet, when a trigger signal is received and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, the process of adjusting the target suspension gap of the first electromagnet includes:

[0110] If the adjustment priority of the first electromagnet is less than that of the second electromagnet, when a trigger signal is received and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, increasing the target suspension gap of the first electromagnet.

[0111] As an alternative embodiment, the process of decreasing the target suspension gap of the first electromagnet includes:

[0112] Decreasing the target suspension gap of the first electromagnet by a fifth preset step size;

[0113] Correspondingly, the process of increasing the target suspension gap of the first electromagnet includes:

[0114] Increasing the target suspension gap of the first electromagnet by a sixth preset step size.

[0115] Specifically, adjustment rules can be preset. For example, the adjustment rule is to preferentially adjust the suspension gap of the electromagnet with a smaller current or the suspension gap of the electromagnet with a larger current. The control logics corresponding to the above two adjustment rules are described below respectively.

[0116] 1. Describe the adjustment rule of preferentially adjusting the suspension gap of the electromagnet with a larger current. Assume that the current \(I_A\) of electromagnet A is greater than the current \(I_B\) of electromagnet B. Then controller A preferentially adjusts the target suspension gap of electromagnet A. During any adjustment when the target suspension gap of electromagnet A has not reached its corresponding preset threshold and makes the overlapping structure meet the current balance condition, controller A will no longer adjust the target suspension gap of electromagnet A. If the target suspension gap of electromagnet A reaches the preset threshold and the overlapping structure still does not meet the current balance condition, controller A will also no longer adjust the target suspension gap of electromagnet A. At this time, controller A generates a trigger signal to trigger controller B to adjust the target suspension gap of electromagnet B until the overlapping structure meets the current balance condition.

[0117] Specifically:

[0118] For controller A, the first current \(I_A\) it obtains is greater than the second current \(I_B\). Then controller A determines that the adjustment priority of its corresponding first electromagnet (i.e., electromagnet A) is higher than that of its corresponding second electromagnet (i.e., electromagnet B). At this time, controller A preferentially adjusts the target suspension gap of electromagnet A. The adjustment process includes: determining whether the current suspension gap of its corresponding first electromagnet (i.e., electromagnet A) reaches its corresponding preset threshold. If not, then adjust the target suspension gap of electromagnet A. Since the first current \(I_A\) obtained by controller A is greater than the second current \(I_B\), therefore, the process of controller A adjusting the target suspension gap of electromagnet A is to increase the target suspension gap of the electromagnet, thereby reducing the current of electromagnet A, making the current of electromagnet A and the current of electromagnet B tend to be the same, and further making the overlapping structure meet the current balance condition. As an optional embodiment, to avoid over-adjustment, the process of increasing the target suspension gap of electromagnet A is to increase it periodically, and each period is increased Δs3 , Δs3 by a third preset step length. When the target suspension gap is less than the preset threshold, as long as the overlapping structure meets the current balance condition, the target suspension gap of electromagnet A will no longer be adjusted. If in a certain period, controller A determines that the current target suspension gap of electromagnet A has increased to its corresponding preset threshold, but the overlapping structure still does not meet the current balance condition, the target suspension gap of electromagnet A will also no longer be adjusted. At this time, a trigger signal is generated and sent to controller B so that controller B can adjust the suspension gap of the second electromagnet (i.e., electromagnet B) corresponding to controller A after receiving the trigger signal.

[0119] For controller B, if the first current \(I_B\) it obtains is less than the second current \(I_A\), then controller B determines that the adjustment priority of its corresponding first electromagnet (i.e., electromagnet B) is lower than that of its corresponding second electromagnet (i.e., electromagnet A). At this time, controller B temporarily does not adjust the target suspension gap of electromagnet B and waits to receive the trigger signal sent by controller A. When controller B receives the trigger signal sent by controller A, it then adjusts the target suspension gap of electromagnet B. The adjustment process includes: determining whether the current target suspension gap of electromagnet B reaches its corresponding preset threshold. If not, adjust the target suspension gap of electromagnet B. Considering that the first current \(I_B\) obtained by controller B is less than the second current \(I_A\), the process of controller B adjusting the target suspension gap of electromagnet B is to decrease the target suspension gap of electromagnet B to increase the current of electromagnet B, so that the current of electromagnet B and the current of electromagnet A tend to be the same, thereby making the overlapping structure meet the current balance condition. It can be understood that the process of decreasing the target suspension gap of electromagnet B is decreased periodically, and each period is decreased based on the current target suspension gap Δs4 , Δs4 which is the fourth preset step size. When the target suspension gap has not been decreased to the preset threshold, as long as the overlapping structure meets the current balance condition, the target suspension gap of electromagnet B will no longer be adjusted.

[0120] 2. Explain the adjustment rule of preferentially adjusting the suspension gap of the electromagnet with a smaller current. Assume that the current \(I_A\) of electromagnet A is greater than the current \(I_B\) of electromagnet B. Then controller B preferentially adjusts the target suspension gap of electromagnet B. When any adjustment when the target suspension gap of electromagnet B has not reached its corresponding preset threshold makes the overlapping structure meet the current balance condition, controller B will no longer adjust the target suspension gap of electromagnet B. If the target suspension gap of electromagnet B reaches the preset threshold and the overlapping structure still does not meet the current balance condition, controller B will also no longer adjust the target suspension gap of electromagnet B. At this time, controller B generates a trigger signal to trigger controller A to adjust the target suspension gap of electromagnet A until the overlapping structure meets the current balance condition.

[0121] Specifically:

[0122] For controller A, if the first current \(I_A\) it obtains is greater than the second current \(I_B\), then controller A determines that the adjustment priority of its corresponding first electromagnet (i.e., electromagnet A) is lower than that of its corresponding second electromagnet (i.e., electromagnet B). At this time, controller A temporarily does not adjust the target suspension gap of electromagnet A and waits to receive the trigger signal sent by controller B.

[0123] For controller B, if the first current \(I_B\) it obtains is less than the second current \(I_A\), then controller B determines that the adjustment priority of its corresponding first electromagnet (i.e., electromagnet B) is higher than that of its corresponding second electromagnet (i.e., electromagnet A). At this time, controller B preferentially adjusts the target suspension gap of electromagnet B. The adjustment process includes: judging whether the current target suspension gap of electromagnet B reaches its corresponding preset threshold. If not, adjust the target suspension gap of electromagnet B. Considering that the first current \(I_B\) is less than the second current \(I_A\), the process of controller B adjusting the target suspension gap of electromagnet B is to reduce the target suspension gap of electromagnet B to increase the current of electromagnet B, so that the current of electromagnet B and the current of electromagnet A tend to be the same, thereby making the overlapping structure meet the current balance condition.

[0124] As an optional embodiment, the process of reducing the target suspension gap of electromagnet B is to reduce it periodically, and each period is to reduce it based on the current target suspension gap Δs5 , Δs5 which is the fifth preset step length. When the target suspension gap is greater than the preset threshold, as long as the overlapping structure meets the current balance condition, the target suspension gap of electromagnet B will no longer be adjusted. If in a certain period, controller B determines that the current target suspension gap of electromagnet B has been reduced to its corresponding preset threshold, but the overlapping structure still does not meet the current balance condition, the target suspension gap of electromagnet B will no longer be adjusted either. At this time, a trigger signal is generated and sent to controller A so that controller A can adjust the suspension gap of the second electromagnet (i.e., electromagnet A) corresponding to controller B after receiving the trigger signal.

[0125] After receiving the trigger signal sent by controller B, controller A adjusts the target suspension gap of electromagnet A. The adjustment process includes: judging whether the current suspension gap of its corresponding first electromagnet (i.e., electromagnet A) reaches its corresponding preset threshold. If not, then adjust the target suspension gap of electromagnet A. Since the first current \(I_A\) obtained by controller A is greater than the second current \(I_B\), therefore, the process of controller A adjusting the target suspension gap of electromagnet A is to increase the target suspension gap of the electromagnet, thereby reducing the current of electromagnet A, so that the current of electromagnet A and the current of electromagnet B tend to be the same, thereby making the overlapping structure meet the current balance condition. It can be understood that the process of increasing the target suspension gap of electromagnet A is to increase it periodically, and each period is to increase it based on the current target suspension gap Δs6 , Δs6 which is the sixth preset step length.

[0126] Among them, the set values of the third preset step length, the fourth preset step length, the fifth preset step length, and the sixth preset step length can be the same or different, and can be set according to actual engineering needs. This application does not make specific limitations here.

[0127] In a second aspect, please refer to Figure 2 , Figure 2 which is a schematic structural diagram of an electromagnet control system provided by this application and is applied to a controller. The electromagnet control system includes:

[0128] An acquisition module 1, configured to acquire a first current of a first electromagnet and a second current of a second electromagnet corresponding to an overlapping structure of a maglev train. Among them, the first electromagnet and the controller are in the same single-point suspension system, and the second electromagnet and the controller are in different single-point suspension systems;

[0129] A judgment module 2, configured to judge whether the overlapping structure meets the current balance condition based on the first current and the second current. If not, trigger an adjustment module 3;

[0130] An adjustment module 3, configured to adjust the suspension gap of the first electromagnet and / or the second electromagnet so that the overlapping structure meets the current balance condition.

[0131] It can be seen that in this embodiment, the current balance state of the overlapping structure is determined according to the current magnitudes of the two electromagnets in the overlapping structure of the maglev train. If the current of the overlapping structure is unbalanced, the suspension gap of the first electromagnet and / or the second electromagnet in the overlapping structure is adjusted, thereby adjusting the current of the first electromagnet and / or the second electromagnet, so that the overlapping structure reaches current balance, solving the problem that the current of a single electromagnet is too large and the heat generation is obvious, which is beneficial to the long-term operation of the maglev train.

If the overlapping structure does not meet the current balance condition after the target suspension gap reaches its corresponding preset threshold, generate a trigger signal and stop adjusting the target suspension gap of the first electromagnet;

[0148] If the adjustment priority of the first electromagnet is less than that of the second electromagnet, when a trigger signal is received and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, adjust the target suspension gap of the first electromagnet until the overlapping structure meets the current balance condition.

[0152] If the adjustment priority of the first electromagnet is lower than that of the second electromagnet, when a trigger signal is received and the current target suspension gap of the first electromagnet has not reached its corresponding preset threshold, reduce the target suspension gap of the first electromagnet.
