Description

Technical Field

[0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a current collector control system and method for a high-speed maglev vehicle. Background Art

[0002] At the power rail installed on the high-speed maglev line, that is, the auxiliary parking area or station, the on-board battery is charged by extending the current collector to contact the power rail. When the speed exceeds a certain value, the train itself has the function of generating electricity, and there is no need to charge the on-board battery through the current collector. Continuing to extend the current collector will cause damage to the equipment. Therefore, the on-board transportation control system needs to control the retraction and extension of the current collector to ensure that the extension of the current collector is allowed only when it is safe.

[0003] There are two main current collection methods: pantograph and collector shoe. The pantograph is a device installed on the top of the train, which is used to contact the contact network to provide power for the train. When the train enters the power supply area, the pantograph needs to be raised to contact the cable; when the train leaves the power supply area, the pantograph needs to be lowered in time to avoid wear. The collector shoe is set parallel to the power rail next to the track, and the train transmits electricity through sliding contact between the collector shoe and the power rail. In order to ensure the stability of the contact, the control system of the collector shoe is usually equipped with an automatic alignment function to ensure smooth contact with the power rail during high-speed travel of the train, reducing arc generation and equipment wear.

[0004] However, the existing processing methods all rely entirely on manual judgment to operate the extension and retraction of the current collector, which not only consumes a lot of manpower and is too costly, but also may lead to safety hazards caused by operational errors. Summary of the invention

When the current collector is detected to be extended due to a fault, the current collector is controlled to be retracted and the traction power supply is cut off.

[0006] In order to solve the above technical problems, the first aspect of the present invention provides a high-speed maglev train current collector control system, the system comprising: an on-board operation control system, a zone operation control system, a driver console and a current collector; The on-board transportation control system is used to receive the train position and speed information and send it to the zone transportation control system; and is used to determine that the current position of the train is at a station or an auxiliary parking area and the speed is stationary, or the train destination is a station or an auxiliary parking area and the speed is less than a preset value, and control the extension of the current collector; The zoned transport control system is used to determine the train speed. When the train speed is greater than a preset value and the current collector is extended, a command to retract the current collector is sent to the on-board transport control system and the traction is cut off to stop the train. The driver console is used to send a control instruction to the onboard transportation control system to control the extension or retraction of the current collector when the onboard transportation control system is in the non-traction maintenance mode and the train lands; The current receiver is used to perform an extension or retraction operation according to an extension or retraction command of the vehicle-borne transportation control system.

It should also be understood that although the first, second, third and other attributives representing the numbers may be used herein to describe various devices, elements, components or parts, these devices, elements, components or parts should not be limited by these attributives. In other words, these attributives are only used to distinguish one from another. For example, the first device may also be called the second device, but it does not deviate from the essential technical solution of the present invention. In addition, the terms "and / or" and "and / or" refer to all combinations including any one or more of the listed items.

[0018] See also Figure 1 , Figure 1 The structure diagram of a current collector control system for a high-speed maglev train provided by the present invention is as follows: Figure 1 As shown, the system includes: an on-board transportation control system, a zone transportation control system, a driver console and a current receiver.

[0019] In this embodiment, the on-board transportation control system is used to receive the train position and speed information and send it to the zone transportation control system; and is used to determine that the current position of the train is at a station or an auxiliary parking area and the speed is stationary, or the train destination is a station or an auxiliary parking area and the speed is less than a preset value, and control the extension of the current receiver.

[0020] In this embodiment, the zoned operation control system is specifically used to determine the train speed. When the train speed is greater than a preset value and the current collector is extended, a command to retract the current collector is sent to the on-board operation control system and the traction is cut off to stop the train.

[0021] In this embodiment, the driver console is specifically used to send a control instruction to the onboard transportation control system to control the extension or retraction of the current collector when the onboard transportation control system is in the non-traction maintenance mode and the train lands.

[0022] In this embodiment, the current receiver is specifically used to perform an extension or retraction operation according to an extension or retraction command of the vehicle-borne transportation control system.

[0023] In this embodiment, the vehicle-mounted positioning device is specifically used to provide the train position and speed information to the vehicle-mounted transportation control system.

[0024] In this embodiment, the traction system is specifically used to receive the traction cut-off instruction sent by the zoned operation control system, and cut off the traction and stop the vehicle.

[0025] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of a method for controlling a current collector of a high-speed maglev train provided by the present invention. Figure 2 As shown, the system includes: S11. Obtain train position and speed information.

[0026] In this embodiment, the train position and speed information are obtained. The train position can be obtained by obtaining the current position coordinates, or by obtaining the current position identifier, that is, whether it is in a designated area, or by installing a position sensor on the train to obtain it directly. The speed information can be obtained by measuring the speed measuring instrument of the maglev train itself, which is composed of technical principles such as induction motors, timing systems, and sensors. The induction motor uses the principle of magnetic induction to sense the motion state of the train, and the timing system records the time the train has experienced from the beginning to the end, and calculates the train's motion speed based on the train's running time and motion state.

[0027] S12. Extend or retract the current collector according to the current train position, speed, mode information of the driver's console and the onboard transportation control system, and the current train status.

[0028] In this embodiment, the current collector refers to a power receiving device that connects the rail vehicle to the power supply rail, and is usually arranged under the doors on both sides of the rail vehicle.

[0029] In this embodiment, the present invention adopts a current receiver that can be controlled to extend. When the current receiver needs to receive current, the current receiver is extended so that the current receiver contacts the power supply rail and can dynamically draw current from the power supply rail. When the current receiver does not need to receive current, the current receiver is retracted so that the current receiver is separated from the power supply rail, thereby reducing the wear on the current receiver and increasing the service life of the current receiver.

[0030] See also Figure 3 , Figure 3 The second flow chart of a high-speed maglev train current collector control method provided by the present invention is as follows: Figure 3 As shown, the method includes: S21. When the onboard transportation control system is in the non-traction maintenance mode, after the train lands, it receives a control instruction from the driver's console to control the current collector to extend or retract.

[0031] In this embodiment, the power supply system provides power to the train through traction. When the onboard transportation control system is in the non-traction maintenance mode, that is, when the train has no power, the train will slow down until it lands, at which time it will receive instructions from the driver's console to extend and retract.

[0032] S22. When the on-board transportation control system is not in the no-traction maintenance mode, the current position of the train is at a station or an auxiliary parking area and is stationary, or the train destination is a station or an auxiliary parking area and the speed is less than a preset value, the current collector is controlled to extend.

[0033] In this embodiment, when the train is also in on-board operation control and not in the no-traction maintenance mode, if the train is currently at a station or auxiliary parking area and is in a stopped state, the train can be charged and the current collector can be controlled to extend.

[0034] In this embodiment, when the train is also in on-board operation control and not in the no-traction maintenance mode, the train destination is a station or an auxiliary parking area, and the speed is less than a preset value, the train can be charged and the current collector can be controlled to extend.

[0035] S23. When neither the onboard transportation control system being in the no-traction maintenance mode nor the onboard transportation control system being in the no-traction maintenance mode conforms to the current train status, the current collector is controlled to be retracted.

[0036] In this embodiment, when none of the above conditions meet the current train status, it means that the train does not meet the charging conditions at this time, and the current collector is controlled to be retracted.

[0037] In this embodiment, when the train speed is greater than a preset value, the train's self-generated electricity is sufficient to provide train operation. If the current collector is extended at this time, the zoning operation control system needs to send a current collector retraction command to cut off traction and stop the train.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
