[0030] Embodiment 1

[0031] Figure 1 This is a flow chart of a high-speed maglev train holding brake control method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling the holding brake of a high-speed maglev train. The method is executed by a zoning operation control device in a high-speed maglev train holding brake control system. The high-speed maglev train holding brake control system can be implemented in the form of hardware and / or software and can be configured in an electronic device. It should be noted that the high-speed maglev train holding brake control system includes a central operation control device, a positioning and speed measuring device, a zoning operation control device, a traction control device and an on-board operation control device. Figure 1 As shown, the method includes:

[0032] S101. After receiving the route instruction sent by the central operation control equipment, the current speed and current position of the target train are obtained through the positioning speed measuring equipment.

[0033] The route instruction refers to the instruction used to control the running path of the high-speed maglev train in the station or section. The target train refers to the high-speed maglev train whose running control is required. The current speed refers to the speed of the target train at the current moment. The current position refers to the position of the target train at the current moment.

[0034] Specifically, after receiving the route instruction sent by the central operation control device, the sub-area operation control device obtains the current speed and current position of the target train through the positioning speed measuring device.

[0035] S102: Determine whether the target train is in a stopped state according to the current speed and the current position.

[0036] Specifically, if the zoned operation control device detects that the current position is within the designated parking area and the current speed is less than the speed threshold within the first preset time, it is determined that the target train is in a parking state and S103 is executed. Otherwise, it is determined that the target train is in a non-parking state, and the zoned operation control device can control the target train to stop at the designated parking point through the on-board control device based on the current speed and current position and the preset speed control algorithm. Among them, the first preset time and the speed threshold can be pre-set according to actual business needs or the experience of those skilled in the art, and the embodiments of the present invention do not specifically limit them.

[0037] S103. When it is determined that the target train is in a stopped state, a traction cut-off instruction is sent to the traction control device, and a holding brake instruction is sent to the target train through the onboard transportation control device, so that the target train executes the holding brake instruction and maintains the braking state.

[0038] The traction cut-off command is a command for causing the target train to lose traction, and the brake holding command is a command for causing the target train to maintain a brake state.

[0039] Specifically, when the section operation control equipment determines that the target train is in a stopped state, it sends a traction cut-off command to the traction control equipment through a relay, so that the traction control equipment cuts off the power supply to the track and causes the target train to lose traction; and sends a holding brake command to the target train through the on-board operation control equipment, so that the target train executes the holding brake command and maintains the braking state.

[0040] The technical solution of the embodiment of the present invention, after receiving the route instruction sent by the central operation control device, obtains the current speed and current position of the target train through the positioning speed measuring device; determines whether the target train is in a stopped state according to the current speed and current position; when it is determined that the target train is in a stopped state, sends a traction cut-off instruction to the traction control device, and sends a holding brake instruction to the target train through the on-board operation control device, so that the target train executes the holding brake instruction and maintains the braking state. The above technical solution realizes the control of holding the brake when the high-speed maglev train stops, avoids the phenomenon of slipping when the high-speed maglev train stops, thereby avoiding the problem of train collision caused by slipping, improving the operation safety of the high-speed maglev train, and ensuring the safety of people in the high-speed maglev train.

[0041] Embodiment 2

[0042] Figure 2This is a flowchart of a high-speed maglev train holding brake control method provided in Example 2 of the present invention. Based on the above examples, this example provides an optional implementation scheme for alleviating the holding brake state of a high-speed maglev train. It should be noted that for the parts not described in detail in the examples of the present invention, reference can be made to the relevant descriptions of other examples. Figure 2 As shown, the method is executed by a partition operation control device in a high-speed maglev train holding brake control system, and includes:

[0043] S201. After receiving the route instruction sent by the central operation control equipment, the current speed and current position of the target train are obtained through the positioning speed measuring equipment.

[0044] S202: Determine whether the target train is in a stopped state according to the current speed and the current position.

[0045] S203. When it is determined that the target train is in a stopped state, a traction cut-off instruction is sent to the traction control device, and a holding brake instruction is sent to the target train through the onboard transportation control device, so that the target train executes the holding brake instruction and maintains the braking state.

[0046] S204. When it is detected that the target train meets the train departure conditions, the maximum speed protection curve, the current speed and the current position of the target train are obtained, and the maximum speed protection curve, the current speed and the current position are sent to the traction control device, so that the traction control device generates the target traction force required for the target train to travel according to the maximum speed protection curve, the current speed and the current position.

[0047] Among them, the train departure conditions refer to the conditions for the target train to depart; optionally, the train departure conditions include but are not limited to the route has been completed, the movement authorization has been calculated, and the departure time in the timetable has arrived. Among them, the route has been completed means that the travel path of the target train has been correctly set and confirmed; the movement authorization refers to the right or permission for the target train to travel in a specific section. The maximum speed protection curve refers to the curve used to limit the maximum operating speed of the target train and prevent the target train from speeding. The target traction force refers to the traction force required for the target train to travel.

[0048] Specifically, when the zoning operation control device detects that the target train meets the train departure conditions, it uses a specific maximum speed protection curve calculation algorithm to calculate the maximum speed protection curve of the target train based on the line data and train data; obtains the current speed and current position of the target train through the positioning speed measuring device; and sends the maximum speed protection curve, current speed and current position to the traction control device, so that the traction control device generates the target traction required for the target train to travel based on the maximum speed protection curve, current speed and current position and based on a specific traction calculation model. Among them, the line data includes but is not limited to the line slope, curve radius and maximum allowable speed; the train data includes but is not limited to the train length, train weight, train acceleration, train expected running speed curve, train safety braking data and train stop point information.

[0049] Optionally, the zone operation control device may also send line data and train data to the traction control device, so that the traction control device determines the train operation data of the target train according to the maximum speed protection curve, line data and train data, and sends the train operation data to the target train. The train operation data includes but is not limited to the phase and amplitude of the stator winding voltage and the phase and amplitude of the stator winding current.

[0050] S205: Receive the target traction force sent by the traction control device, and obtain the train braking force of the target train through the on-board transportation control device.

[0051] The train braking force refers to the braking capacity generated by the train during its travel. Specifically, the zoned operation control device receives the target traction force sent by the traction control device, and obtains the train braking force of the target train through the onboard operation control device.

[0052] S206: Generate a brake release instruction based on the target traction force and the train braking force.

[0053] The brake release command is a command to release the target train from the brake state. Specifically, the target traction force and the train braking force are summed to obtain the target resultant force; when it is detected that the target resultant force is greater than the train resistance of the target train, the brake release command is generated.

[0054] The target resultant force refers to the sum of the target traction force and the train braking force. The train resistance refers to the resistance encountered by the train during its travel; optionally, the train resistance includes but is not limited to air resistance and ramp resistance.

[0055] More specifically, the section operation control equipment sums the target traction force and the train braking force to obtain the target resultant force; when the section operation control equipment detects that the target resultant force is greater than the train resistance exerted on the target train, it generates a maintenance braking relief instruction.

[0056] S207. Send a brake release command to the target train through the on-board transportation control equipment, so that the target train executes the brake release command and releases the brake state.

[0057] Specifically, the section operation control device sends a holding brake release instruction to the target train through the on-board operation control device, so that the target train executes the holding brake release instruction and releases the holding brake state.

[0058] The technical solution of the embodiment of the present invention is as follows: after receiving the route instruction sent by the central operation control device, the current speed and current position of the target train are obtained through the positioning and speed measuring device; according to the current speed and current position, it is determined whether the target train is in a stopped state; when it is determined that the target train is in a stopped state, a traction cut-off instruction is sent to the traction control device, and a holding brake instruction is sent to the target train through the on-board operation control device, so that the target train executes the holding brake instruction and maintains the braking state; when it is detected that the target train meets the train departure conditions, the maximum speed protection curve, the current speed and the current position of the target train are obtained, and the maximum speed protection curve, the current speed and the current position are sent to the traction control device, so that the traction control device generates the target traction force required for the target train to travel according to the maximum speed protection curve, the current speed and the current position; the target traction force sent by the traction control device is received, and the train braking force of the target train is obtained through the on-board operation control device; according to the target traction force and the train braking force, a holding brake release instruction is generated; and the holding brake release instruction is sent to the target train through the on-board operation control device, so that the target train executes the holding brake release instruction and releases the holding brake state. The above technical scheme, when it is detected that the target train meets the conditions for train departure, realizes the relief of the braking state of the high-speed maglev train, thereby avoiding the slipping of the high-speed maglev train due to insufficient traction in the initial stage of traction establishment, thereby avoiding the problem of train collision caused by slipping, improving the operation safety of the high-speed maglev train, and ensuring the safety of people in the high-speed maglev train.

[0059] On the basis of the above embodiment, as an optional method of the embodiment of the present invention, a brake hold relief instruction can also be generated in the following manner: a brake hold relief instruction is generated according to the current vehicle speed. Specifically, the partition operation control device detects whether the current vehicle speed exceeds the preset speed; if so, a brake hold relief instruction is generated. Among them, the preset speed can be pre-set according to actual business needs or the experience of those skilled in the art, and the embodiment of the present invention does not specifically limit it.

[0060] Based on the above embodiment, as an optional method of the embodiment of the present invention, the brake release command can also be generated in the following manner: detecting whether the application time of the traction command is greater than the second preset time; if so, generating the brake release command. The second preset time can be preset according to actual business needs or the experience of those skilled in the art, and the embodiment of the present invention does not specifically limit it.

[0061] Specifically, the zone operation control device detects whether the application time of the traction command is greater than the second preset time; if so, a holding brake release command is generated.
