Description

Technical Field

[0001] The present application relates to the field of track control technology, and in particular to a track stator segment control method and system for a maglev train. Background Art

[0002] The track for a maglev train is composed of multiple traction sections connected end to end. Each traction section is composed of multiple stator segments connected end to end. The stator segments are used to generate a magnetic field that interacts with the electromagnets on the maglev train, thereby pulling the maglev train to move. In order to pull the maglev train to move through the stator segments, it is necessary to control the stator segments on the track for the maglev train.

[0003] Reference Figure 1 At present, the method for controlling the stator segment on the track for maglev trains is as follows: the operation control system sends a speed limit curve (including a stop point) to the traction control system, the traction control system sends a separation command to the stator segment switch station according to the speed limit curve, the stator switch station controls the switch between the converter system and the stator segment to close according to the separation command, and then the stator switch station sends the switch state of the switch to the traction control system, so that the traction control system further controls the converter system to control the stator segment to power on.

[0004] However, the above-mentioned method of controlling the stator segments on the track for maglev trains has a slow control response speed due to the large number of intermediate links in the control link setting, making it difficult for the existing method of controlling the stator segments on the track for maglev trains to meet the traction control requirements of high-speed maglev trains. Summary of the invention

[0018] The above-mentioned method and system for controlling the stator segment of the track for maglev trains generates a route command based on the target train position information, the target train speed and the train operation plan; determines the route partition and the turnout in the route corresponding to the route command in the preset interlocking table; determines the target stator segment corresponding to the route command based on the route partition and the turnout in the route; and controls the target stator segment to be powered on.

The method includes:

[0033] S110, generating a route command based on the target train position information, the target train speed and the train operation plan.

[0034] It should be noted that the track stator segment control method for a maglev train described in this embodiment is based on Figure 3The stator segment control system of a maglev train track shown is executed. Specifically, the stator segment control system of the maglev train track includes a vehicle-mounted positioning device, the vehicle-mounted positioning device is used to obtain the position information of the target train, the vehicle-mounted positioning device is communicatively connected with the vehicle-mounted operation control, the vehicle-mounted operation control is used to control the operation of the target train, the vehicle-mounted operation control is communicatively connected with the operation control component, and the operation control component includes a zone operation control and a central operation control; the maglev train track is divided into a plurality of traction zones, each traction zone is divided into a plurality of stator segments, each traction zone is provided with a one-to-one corresponding zone operation control, the zone operation control is used to monitor the corresponding traction zone, each zone operation control is communicatively connected with the central operation control, some traction zones may be provided with turnouts, the turnouts are used to make the target train run from the current maglev train track to the adjacent maglev train track, if there is a turnout in a traction zone, the turnout is communicatively connected with the zone operation control corresponding to the traction zone; each stator segment is provided with a corresponding stator segment switch, and the zone operation control is communicatively connected with the stator segment switch of each stator segment in the corresponding traction zone.

[0035] The target train position information includes at least: the current position, the current partition, and the train offset. The target train is a maglev train participating in a maglev train track stator segment control method in this embodiment. The current position is the specific position of the target train at the current moment. The current partition is the specific traction partition where the target train is located at the current moment. For example, refer to Figure 4 , the target train is currently in the traction section 1G, then the current section corresponding to the target train at the current moment is 1G; the train offset is the direction in which the target train moves from one end of the traction section to the other end; the target train is also equipped with a speed detection device, which is used to detect the running speed of the target train to obtain the target train speed; the central operation control can obtain the manually input train operation plan, which specifically includes the stopover stations of each maglev train, the stopover duration corresponding to the stopover stations, the departure time, and the next stopover station and other information. The target train can send the target train position information and target train speed to the central operation control through its on-board positioning device and speed detection device. Furthermore, the central operation control can generate a route command based on the target train position information, target train speed and the obtained train operation plan. The route command is such as Figure 4 Route001 is indicated by the dotted arrow. The traction divisions involved in Route001 are 2DG, 1DG, and 4DG. The turnouts involved in Route001 are turnout 2 and turnout 1 marked with yellow numbers, and turnout 4 marked with green numbers.

[0036] Specifically, the target train obtains the target train position information and target train speed in real time during its operation, and sends the target train position information and target train speed to the central operation control. Furthermore, the central operation control generates an approach command based on the target train position information, target train speed and the obtained train operation plan.

[0037] S120, determining the route partition and the intra-route turnout corresponding to the route command in the preset interlocking table.

[0038] Among them, the interlocking table is used to record the traction sections and switches involved in the operation process of each maglev train; the route command corresponds to the corresponding traction section and switch; the route section is the traction section that is repeated in the route command in the interlocking table, and the switch within the route is the switch that is repeated in the route command in the interlocking table.

[0039] Specifically, the traction partition that is repeated with the route command in the preset interlocking table is determined to obtain the route partition, and the switch that is repeated with the route command in the preset interlocking table is determined to obtain the intra-route switch.

[0040] S130. Determine a target stator segment corresponding to the route command based on the route partition and the switches within the route.

[0041] The target stator segment is the part where the route command and the route partition involved are repeated, such as Figure 4 Green line section shown. The target stator segment is determined based on the route partitions and the turnouts within the route.

[0042] Specifically, the target stator segment corresponding to the route command is determined according to the route partition corresponding to the route command and the switches within the route.

[0043] S140. Control the target stator segment to be powered on.

[0044] Among them, the central operation control can send the generated route command to the corresponding partition operation control, so that the partition operation control controls the target stator segment corresponding to it to be powered on; for example, taking an approach partition corresponding to the route command as an example, refer to Figure 3 and Figure 4 The central operation control sends the route command to the sub-district operation control corresponding to the route partition 2DG corresponding to the route command. The target stator segment corresponding to the route partition 2DG and the route command is all the stator segments between the left end of 2DG and the switch 2 as shown in 4; the sub-district operation control corresponding to the route partition 2DG turns on all the stator segment switches of its corresponding target stator segment according to the route command, thereby powering on the target stator segment.

[0045] Specifically, the zoned operation and control receives the route command issued by the central operation and control, and controls the corresponding target stator segment to be powered on.

[0046] It should be noted that this embodiment generates a route command based on the target train position information, the target train speed, and the train operation plan; determines the route partition and the on-route turnout corresponding to the route command in the preset interlocking table; determines the target stator segment corresponding to the route command based on the route partition and the on-route turnout; and controls the target stator segment to be powered on. Through the above implementation, after the route command is generated, the route partition and the on-route turnout corresponding to the route command can be directly determined, and the target stator segment can be further determined based on the route partition and the on-route turnout, and then the target stator segment is powered on to achieve control of the stator segment, which makes it easy to simplify the control process of the stator segment, thereby improving the response speed of controlling the stator segment, and further making it easy to control the stator segment on the track of the maglev train to meet the traction control requirements of the high-speed maglev train.

[0047] Embodiment 2

[0048] Embodiment 2 of the present application provides a method for controlling a track stator segment for a maglev train, which optimizes the "generating a route command based on target train position information, target train speed, and train operation plan" in Embodiment 1; it should be noted that for the parts not described in detail in this embodiment, reference may be made to the descriptions of other embodiments, and the method includes:

[0049] S211. Determine whether to trigger the generation of a route command based on the target train position information.

[0050] Among them, whether to trigger the generation of the route command can be determined by the current partition in the target train position information; when the current partition of the target train is the designated traction partition, it is necessary to trigger the generation of the route command, wherein the designated traction partition can be the first traction partition between the starting station and the terminal station of the target train, or the first traction partition after the end of the track route corresponding to a route command, or a traction partition specified by the user.

[0051] Specifically, the current partition in the target train position information is obtained in real time, and it is determined whether the current partition is a designated traction partition, so as to determine whether to trigger the generation of a route command.

[0052] S212: If yes, generate a route command based on the target train speed and the train operation plan.

[0053] Among them, if it is determined that the current section is a designated traction section, it is necessary to trigger the generation of an approach command; the approach command can be generated by processing the target train speed obtained through the degree and the train operation plan.

[0054] Specifically, the acquired target train speed and train operation plan are processed to generate a route command.

[0055] S220. Determine the route partition and the intra-route turnout corresponding to the route command in the preset interlocking table.

[0056] S230. Determine a target stator segment corresponding to the route command based on the route partition and the switches within the route.

[0057] S240: Control the target stator segment to be powered on.

[0058] Embodiment 3

[0059] Embodiment 3 of the present application provides a method for controlling a track stator segment for a maglev train, which optimizes the "generating a route command based on the target train speed and the train operation plan" in Embodiment 2; it should be noted that for the parts not described in detail in this embodiment, reference may be made to the descriptions of other embodiments, and the method includes:

[0060] S311. Determine whether to trigger the generation of a route command based on the target train position information.

[0061] S312A: If yes, determine whether the target train speed is greater than the first speed threshold but not greater than the second speed threshold.

[0062] Among them, a first speed threshold and a second speed threshold are preset for the target train speed, and then by comparing the acquired target train speed with the first speed threshold and the second speed threshold, it can be determined how many route commands are generated for the target train in a continuous time sequence.

[0063] Specifically, if it is determined that the route generation command needs to be triggered, it is further determined whether the target train speed is greater than the first speed threshold but not greater than the second speed threshold.

[0064] S312B: If yes, generate a route command according to the train operation plan.

[0065] Among them, when the speed of the target train is greater than the first speed threshold but not greater than the second speed threshold, it means that the speed of the target train is moderate at this time, and it takes a certain amount of time for the target train to complete the track route corresponding to the route command to be generated. At this time, only one route command is generated for the target train; the central operation control can generate a route command corresponding to the target train for the acquired train operation plan, and the route command is generated through the train operation plan, which can ensure that the track route corresponding to the route command is only for the target train to travel. In this way, not only will the target train not affect the operation of other maglev trains when running on the track route corresponding to the route command, but the target train can also run at the maximum speed allowed by the track route as much as possible.

[0066] Specifically, if it is determined that the target train speed is greater than the first speed threshold but not greater than the second speed threshold, the central operation control generates a route command by processing the train operation plan.

[0067] S312C, determine whether the target train speed is greater than a second speed threshold.

[0068] S312D: If yes, generate at least two route commands with a sequential order according to the train operation plan.

[0069] Among them, if the target train speed is greater than the second speed threshold, it means that the speed of the target train is at a relatively high level at this time, and the target train will complete the track route corresponding to the first route command to be generated in a shorter time. At this time, if only one route command is generated for the target train, it is possible that when the target train completes the track route corresponding to the first route command to be generated, the second route command in the timing sequence has not yet been generated, resulting in a failure in the process of towing the target train, and even causing an operation accident of the maglev train; in order to avoid the above-mentioned failures and accidents, when it is determined that the target train speed is greater than the second speed threshold, it is necessary to generate at least two route commands with a chronological order for the target train according to the train operation plan.

[0070] Specifically, if it is determined that the target train speed is greater than the second speed threshold, the central operation control obtains at least two route commands with a chronological order by processing the train operation plan; in this embodiment, the central operation control obtains two route commands with a chronological order by processing the train operation plan. In other embodiments, the number of route commands with a chronological order generated is not limited.

[0071] S320, determining the route partition and the intra-route turnout corresponding to the route command in the preset interlocking table.

[0072] S330. Determine a target stator segment corresponding to the route command based on the route partition and the switches within the route.

[0073] S340, controlling the target stator segment to be powered on.

[0074] Embodiment 4

[0075] A track stator segment control method for a maglev train provided in the fourth embodiment of the present application is provided with reference to Figure 2 The method may be performed by a device for performing the method, and the device may be implemented by software and / or hardware. The method includes:

[0076] S411. Determine whether to trigger the generation of a route command based on the target train position information.

[0077] S412A: If yes, determine whether the target train speed is greater than the first speed threshold but not greater than the second speed threshold.

[0078] S412B: If yes, generate a route command according to the train operation plan.

[0079] S412C, determine whether the target train speed is greater than a second speed threshold.

[0080] S412D: If yes, generate at least two route commands with a sequential order according to the train operation plan.

[0081] S412E, determining whether the track route between the current position of the target train and the starting point of the track route corresponding to the last route command in the time sequence is in a state where the track is idle, the switch position is accurate, and the track is only used by the target train.

[0082] The starting point of the track route corresponding to the last route command in the time sequence is also the end point of the track route corresponding to the second to last route command in the time sequence. For example, assuming that two route commands with a sequential time sequence are generated, such as Figure 4 Route001 and Route002 shown are the track routes between the current position of the target train and the starting point of the track route corresponding to the last route command in the time sequence, that is, the track route from the current position of the target train to the end point of the track route corresponding to Route001; each sub-area operation control can detect the idle state of the track section of the track section where the corresponding traction zone is located in real time, and the central operation control can determine whether the track route between the current position of the target train and the starting point of the track route corresponding to the last route command in the time sequence is in the track idle state by obtaining the idle state of the track section detected by each sub-area operation control; the sub-area operation control corresponding to the switch also sends the corresponding switch position to the central operation control in real time, so that the central operation control can determine whether the track route between the current position of the target train and the starting point of the track route corresponding to the last route command in the time sequence is in the accurate switch position state; the central operation control can determine whether the track route between the current position of the target train and the starting point of the track route corresponding to the last route command in the time sequence is in the state where the track is only used by the target train by analyzing the interlocking table.

[0083] Specifically, the central operation control obtains and processes the idle status of the track section, the switch position and the interlocking table to determine whether the track route between the current position of the target train and the starting point of the track route corresponding to the last approach command in the chronological sequence is in a state where the track is idle, the switch position is accurate and the track is only used by the target train.

[0084] S420. If so, determine the route partition and the route switch corresponding to the route command in the preset interlocking table, wherein the route command is the first route command in the timing sequence.

[0085] Among them, if it is judged whether the track route between the current position of the target train and the starting point of the track route corresponding to the last route command in the time sequence is in a state where the track is idle, the switch position is accurate, and the track is only used by the target train, it means that the track route is suitable for the target train to run next; next, it is necessary to determine the traction partition and switch in the interlocking table that are repeated with the first route command in the time sequence, so as to obtain the route partition and the switch within the route, so as to facilitate the subsequent further determination of the target stator segment.

[0086] S430. Determine a target stator segment corresponding to the route command based on the route partition and the switches within the route.

[0087] S440: Control the target stator segment to be powered on.

[0088] Embodiment 5

[0089] Embodiment 5 of the present application provides a method for controlling a track stator segment for a maglev train, which optimizes the "generating a route command based on the target train speed and the train operation plan" in Embodiment 2; it should be noted that for the parts not described in detail in this embodiment, reference may be made to the descriptions of other embodiments, and the method includes:

[0090] S511. Determine whether to trigger the generation of a route command based on the target train position information.

[0091] S512A: If yes, generate a main route command and a backup route command based on the train operation plan and the target train speed.

[0092] Among them, the route backup command is to prevent the route main command from being unable to execute the generated backup route command due to unexpected circumstances; unexpected circumstances include temporary control of some tracks, emergency maintenance of some tracks, etc.

[0093] Specifically, when it is determined that a route command needs to be triggered, the central operation control generates not only a main route command but also at least one backup route command according to the train operation plan and the target train speed.

[0094] S512B, obtaining the route command based on the route main command and the route backup command.

[0095] Among them, the route command includes the main route command and the backup route command.

[0096] S520, determining the route partition and the intra-route turnout corresponding to the route command in the preset interlocking table.

[0097] S530. Determine a target stator segment corresponding to the route command based on the route partition and the switches within the route.

[0098] S540: Control the target stator segment to be powered on.

[0099] Embodiment 6

[0100] Embodiment 6 of the present application provides a method for controlling a track stator segment for a maglev train, which optimizes the "determining a target stator segment corresponding to the route command based on the route partition and the turnout in the route" in Embodiment 1; it should be noted that for the parts not described in detail in this embodiment, reference may be made to the descriptions of other embodiments, and the method includes:

[0101] S610: Generate a route command based on the target train position information, the target train speed and the train operation plan.

[0102] S620. Determine the route partition and the intra-route turnout corresponding to the route command in the preset interlocking table.

[0103] S631. Determine whether the access partition is in an idle state.

[0104] Among them, one route command may include multiple route partitions. Some or all of the stator segments in the route partition will be needed as the target stator segments for traction of the target train later. Therefore, it is necessary to determine whether the route partition corresponding to the route command is in an idle state; the partition operation control can monitor the idle state of the corresponding traction partition in real time, and send the idle state to the central operation control, so that the central operation control can determine whether the route partition is in an idle state, where the idle state includes idle and not idle.

[0105] Specifically, the central operation control obtains the idle state of the route partition through the partition operation control corresponding to the route partition, thereby determining whether the corresponding route partition is in an idle state.

[0106] S632. If yes, continue to determine whether the switch in the route is in a position corresponding to the route command.

[0107] The status of the turnout in the route corresponding to the route command can be referred to Figure 4For example, the switch in the route corresponding to the route command Route001 is switch 2. The route command is to control the target train to first pass through the first route partition 2DG, and then turn to the second route partition 1DG at switch 2. At this time, switch 2 needs to be in the reverse position. At this time, it is considered that the switch in the route is in the position corresponding to the route command. Switch 1 and switch 4 are the same and will not be repeated. It should be noted that the central operation control can obtain the position of the switch in the route through the partition operation control.

[0108] Specifically, if it is determined that the route partition is in an idle state, it is further determined whether the switches in the route corresponding to the route command are all in the positions corresponding to the route command.

[0109] S633. If not, adjust the switch in the route to the position corresponding to the route command.

[0110] Specifically, if the central operation control determines that the switches in the route are not all at the positions corresponding to the route command, the central operation control controls the corresponding sub-area operation control to adjust the switches in the route to the positions corresponding to the route command.

[0111] S634, locking the approach partition and the switch within the approach to obtain the target partition and target switch.

[0112] Among them, the target partition is the route partition in a locked state, the target turnout is the switch within the route in a locked state, and the target partition and target turnout are only for use by the target train.

[0113] Specifically, the central operation and control locks the approach partition to obtain the target partition, and also locks the switches within the approach to obtain the target switch.

[0114] S635. Obtain a target stator segment corresponding to the route command based on the target partition and the target turnout.

[0115] Among them, the central operation control can determine the stator segment in the target partition that will participate in the traction of the target train, that is, the target stator segment, based on the target partition and the target turnout.

[0116] Specifically, the central operation control determines the stator segment in the target partition that will participate in the traction of the target train based on the target partition and the target turnout, and then hits the target stator segment.

[0117] S640: Control the target stator segment to be powered on.

[0118] Embodiment 7

[0119] Embodiment 7 of the present application provides a method for controlling a track stator segment for a maglev train, which optimizes the "obtaining a target stator segment corresponding to the route command based on the target partition and the target turnout" in Embodiment 6; it should be noted that for the parts not described in detail in this embodiment, reference may be made to the descriptions of other embodiments, and the method includes:

[0120] S710: Generate a route command based on the target train position information, the target train speed and the train operation plan.

[0121] S720. Determine the route partition and the intra-route turnout corresponding to the route command in the preset interlocking table.

[0122] S731. Determine whether the access partition is in an idle state.

[0123] S732. If yes, continue to determine whether the switch in the route is in a position corresponding to the route command.

[0124] S733. If not, adjust the switch in the route to the position corresponding to the route command.

[0125] S734, lock the approach partition and the switch within the route to obtain the target partition and target switch.

[0126] S735A, determine whether the target switch is set on the target partition.

[0127] Among them, the target partition corresponding to the route command may contain a target turnout, such as Figure 4 There is a target turnout (turnout 2) in the target partition 2DG, and there may be no target turnout in the target partition corresponding to the route command. For example, there is no target turnout in the target partition 12G. Therefore, it is necessary to first determine whether there is a target turnout in the target partition.

[0128] Specifically, the central operation control can determine whether a target switch is set on the target partition by querying the interlocking table.

[0129] S735B. If so, determine whether the target turnout is the route starting point or the route end point corresponding to the target partition based on the route command.

[0130] Please refer to Figure 4 In the target partition 2DG, when the target train passes through the target partition 2DG according to the route command, it will enter from the left end of the target partition 2DG and arrive at the target switch (switch 2). At this time, the target switch is also the starting point of the route on the target partition 2DG; when the target train passes through the target partition 1DG according to the route command, it will enter the target partition 1DG from the target switch (switch 1) and exit from the right end of the target partition 1DG. At this time, the target switch is also the end point of the route on the target partition 1DG.

[0131] Specifically, if it is determined that a target turnout is provided on the target partition, it is further determined according to the route command whether the target turnout is the route starting point or the route end point corresponding to the target partition.

[0132] S735C. If it is determined according to the route command that the target turnout is to be the route starting point corresponding to the target partition, the stator segment between the target turnout and the end point of the target partition is used as the target stator segment.

[0133] Among them, the route starting point is the starting position when the target train enters a target section; if the running direction of the target train in a target section is from the left end of the target section to the right end of the target section, the right end of the target section is the end point of the target section; when the target turnout is used as the route starting point on the corresponding target section, the stator segment between the target turnout and the end point of the target section is the target stator segment.

[0134] Specifically, if it is determined according to the route command that the target turnout is to be the route starting point corresponding to the target partition, the stator segment between the target turnout and the end point of the target partition is the target stator segment.

[0135] S735D. If it is determined according to the route command that the target turnout is the route end point corresponding to the target partition, the stator segment between the starting point of the target partition and the target turnout is used as the target stator segment.

[0136] Among them, if the running direction of the target train in a target section is from the left end of the target section to the right end of the target section, the left end of the target section is the starting point of the target section; when the target turnout is the end point of the route on the corresponding target section, the stator segment between the starting point of the target section and the target turnout is the target stator segment.

[0137] Specifically, if it is determined according to the route command that the target turnout is to be the route end point corresponding to the target partition, the stator segment between the starting point of the target partition and the target turnout is used as the target stator segment.

[0138] S740: Control the target stator segment to be powered on.

The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more maglev train track stator segment control device embodiments provided below can refer to the limitations of the maglev train track stator segment control method mentioned above, and will not be repeated here.
