[0002] Low-temperature superconducting electric suspension technology has great potential and advantages in high-speed and ultra-high-speed applications. At the same time, this technology has the unique characteristic that the higher the speed, the smaller the magnetic resistance, as well as auxiliary wheels that provide protection and support in emergency situations. In the future, it will be a ground transportation tool that people have longed for.

[0003] At the same time, the precise parking control system of the low-temperature superconducting maglev train is related to driving safety. Like the wheel-rail and maglev lines that have been in commercial operation, there are strict requirements for the running speed and running time of the train, requiring the train to run on time, safely and comfortably. In addition, due to the characteristics of the ultra-high-speed low-vacuum pipeline superconducting maglev train, during normal operation, the station parking needs to be docked with the connecting bridge, and in the event of a fault, it needs to be docked with the escape passage at the designated location, etc., which puts forward strict requirements for precise parking.

[0004] Since the ultra-high-speed low-vacuum tube superconducting maglev train system structure is different from the existing wheel-rail and maglev, and multiple braking systems are distributed on the ground and on the vehicle, the existing centralized braking force distribution unit architecture design cannot meet the requirements. In addition, there is no design of parking strategies for normal and fault conditions in the existing technology. Summary of the invention

[0018] The embodiment of the present invention further provides a parking control method applicable to an ultra-high-speed low-vacuum pipeline flying train, wherein the method comprises:

[0019] Use the central operation control device, the zone operation control device and the cabin operation control device to carry out the train operation command and safety protection;

[0038] Figure 1 A schematic diagram of a parking control system suitable for an ultra-high-speed low-vacuum tube flying train according to an embodiment of the present invention is shown.

[0039] like Figure 1 As shown, an embodiment of the present invention provides a parking control system suitable for an ultra-high-speed low-vacuum tube flying train, wherein the system includes a ground part and a vehicle-mounted part, the ground part includes a central transportation control device, a partition transportation control device, a traction device and a line device, and the vehicle-mounted part includes a cabin transportation control device, wherein:

[0040] The central operation control device, the partition operation control device and the cabin operation control device are used for train operation command and safety protection;

[0041] The traction device is used to traction train operation;

[0042] The line device is used for vacuum pipeline air pressure control, gate valve control, passenger connection control, turnout control and escape maintenance device control;

[0043] The cabin transportation control device is also used to control the on-board superconducting magnet device, the supporting suspension device (suspension device), the on-board braking device (i.e., the cabin braking device) and the life support device, and the cabin transportation control device coordinates with the zone transportation control device to distribute the braking force during the train stopping process to control the train stopping.

[0044] The traction device and the superconducting magnet device on the train work together to complete the operation of the sports car. The gate valve can divide the pipeline (vacuum pipeline line) into multiple closed and independent small intervals.

[0045] Through the above technical solution, during the process of the zonal operation control device and the cabin operation control device conducting the train operation command and safety protection (i.e., while the zonal operation control device and the cabin operation control device are controlling other devices), the cabin operation control device can coordinate with the zonal operation control device to distribute the braking force during the train parking process to control the train to stop accurately. This solves the problem that the mature and accurate parking technology in the field of rail transportation cannot be directly used due to the incomplete maturity of the ultra-high-speed low-vacuum pipeline maglev transportation system technology.

[0046] According to an embodiment of the present invention, the cabin transport control device and the zone transport control device perform vehicle-ground coordination and distribute the braking force during the train parking process, including:

[0047] When the train-ground wireless communication is normal, the zoned operation control device distributes the braking force during the train parking process;

[0048] In case of abnormal train-to-ground wireless communication, the cabin transport control device distributes the braking force during the train parking process.

[0049] like Figure 2 As shown (taking partition #1 as an example), the partition operation control device may include a partition safety computer and a partition control computer. The partition safety computer is used for the safety protection of the train, and the partition control computer is used for distributing the braking force during the train parking process (ground braking force distribution).

[0050] like Figure 3 As shown, the onboard transport control device may include an onboard safety computer and an onboard control unit, wherein the onboard safety computer is used for the safety protection of the train, and the onboard control unit is used for distributing the braking force during the train parking process (i.e., onboard braking force distribution). The onboard transport control device may also be used to control the onboard power supply device and the docking device.

[0051] That is, when the vehicle-ground wireless communication is normal, the partition computer in the partition operation control device uniformly distributes the braking force; when the vehicle-ground wireless communication is abnormal, the cabin control unit in the cabin operation control device controls the vehicle braking device.

[0052] According to an embodiment of the present invention, the partitioned operation control device distributes the braking force during the train parking process, including:

[0053] Determine whether the current speed of the train is within the predetermined accuracy range. When it is not within the predetermined accuracy range and the current speed of the train reaches the lower limit of the predetermined accuracy range, the zone transportation control device sends braking force control data to the cabin transportation control device via wireless communication, so that the cabin transportation control device controls the on-board braking device to perform braking operations according to the braking force control data.

[0054] Among them, when it is not within the predetermined accuracy range and the current speed of the train reaches the lower limit of the predetermined accuracy range, the traction control exits.

[0055] In this way, accurate stopping control of the train at low speed during normal communication can be achieved.

[0056] In addition, during normal operation, if the train is in the section of the target stopping point, that is, the section where passengers are picked up or the section where the escape maintenance door is located, and the traction accuracy meets the closed-loop control conditions (the current speed is within the predetermined accuracy range), the train can be accurately closed-loop controlled in this case, and the sectional operation control device does not participate in the parking control.

[0057] That is, the partition control device will distribute the braking force only when the current speed is not within the predetermined accuracy range.

[0058] According to an embodiment of the present invention, the cabin transport control device distributes the braking force during the train parking process, including:

[0059] The cabin transport control device controls the on-board braking device to perform braking operations according to the non-collision protection curve, and the partition transport control device and the cabin transport control device synchronously execute the parking point position permission change, adjusting the parking point position to the escape maintenance door closest to the current position of the train.

[0060] In this way, accurate train stopping control can be achieved when abnormal communication occurs.

[0061] The embodiment of the present invention further provides a parking control method applicable to an ultra-high-speed low-vacuum pipeline flying train, wherein the method comprises:

[0062] Use the central operation control device, the zone operation control device and the cabin operation control device to carry out the train operation command and safety protection;

[0063] The train is pulled by a traction device;

[0064] Use line devices to perform vacuum pipeline pressure control, gate valve control, passenger connection control, turnout control, and escape maintenance device control;

[0065] The cabin transport control device is used to control the on-board superconducting magnet device, the supporting suspension device, the on-board braking device and the life support device, and the cabin transport control device cooperates with the partition transport control device to distribute the braking force during the train parking process to control the train parking.

[0066] Through the above technical solution, during the process of the zoning operation control device and the cabin transportation control device conducting the operation command and safety protection of the train, the cabin transportation control device can coordinate with the zoning operation control device to distribute the braking force during the train parking process to control the train to stop accurately. This solves the problem that the mature and accurate parking technology in the field of rail transportation cannot be directly used due to the incomplete maturity of the ultra-high-speed low-vacuum pipeline maglev transportation system technology.

[0067] According to an embodiment of the present invention, the cabin transport control device and the zone transport control device perform vehicle-ground coordination and distribute the braking force during the train parking process, including:

[0068] When the train-ground wireless communication is normal, the zoned operation control device distributes the braking force during the train parking process;

[0069] In case of abnormal train-to-ground wireless communication, the cabin transport control device distributes the braking force during the train parking process.

[0070] According to an embodiment of the present invention, the partitioned operation control device distributes the braking force during the train parking process, including:

[0071] Determine whether the current speed of the train is within the predetermined accuracy range. When it is not within the predetermined accuracy range and the current speed of the train reaches the lower limit of the predetermined accuracy range, the zone transportation control device sends braking force control data to the cabin transportation control device via wireless communication, so that the cabin transportation control device controls the on-board braking device to perform braking operations according to the braking force control data.

[0072] According to an embodiment of the present invention, the cabin transport control device distributes the braking force during the train parking process, including:

[0073] The cabin transport control device controls the on-board braking device to perform braking operations according to the non-collision protection curve, and the partition transport control device and the cabin transport control device synchronously execute the parking point position permission change, adjusting the parking point position to the escape maintenance door closest to the current position of the train.

[0074] It can be seen from the above embodiments that the parking control system and method suitable for an ultra-high-speed low-vacuum tube flying train described in the present invention can complete the control of braking force distribution through the partitioned operation control device in a normal communication operation scenario to achieve precise parking; for abnormal communication operation scenarios, the control of braking force distribution can be completed through the cabin-borne operation control device to achieve the purpose of precise parking.

[0075] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0076] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0077] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0078] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
