Description

Technical Field

[0001] The present disclosure relates to the field of train control technology, and in particular to a method, device, equipment and medium for switching group train operation control rights. Background Art

[0002] A group train refers to a train that is organized and operated according to a group plan through train-to-train communication.

[0003] The current CTCS-3, CBTC, and CTCS-N train control systems all use a target distance method to calculate the primary braking curve. This approach increases the tracking interval between trains as train speed increases, limiting train departure intervals and impacting operating efficiency.

[0004] Through train-to-train communication, according to the marshaling plan, the front and rear trains exchange information such as train position, speed, working conditions, handle position, pipe pressure and tail pressure. The target speed method is used to calculate the braking curve once to realize the train group marshaling operation. The train group marshaling operation shortens the departure interval and tracking distance between trains, greatly improving the line transportation efficiency.

[0005] However, the existing CTCS-3, CBTC, and CTCS-N train control systems only allow one train to trigger the handover function at the handover boundary when performing train handover switching. This cannot meet the handover function in the case of multiple train groups, limiting the availability of the train group operation control system in handover switching scenarios.

[0006] Existing technologies cannot meet the handover and switching requirements of multiple trains in group train formation. Summary of the Invention

[0007] In response to the above problems, the present disclosure provides a method, device, equipment and medium for switching the operation control rights of a group train, which are used to solve the problem of handover and switching of multiple trains in the case of group train formation.

[0008] In a first aspect, a method for switching group train operation control rights is provided, the method comprising:

[0009] The group train adopts the driving permission information of the corresponding ground equipment according to the jurisdiction of the equipment where it is located;

[0010] When a group train runs across equipment jurisdictions, the handover area is determined based on the boundaries between the equipment jurisdictions. According to the train's direction of travel, the handover group control center, referred to as the handover GCC, is the ground equipment in the equipment jurisdiction of the train's current operation area, and the receiving group control center, referred to as the receiving GCC, is the ground equipment in the equipment jurisdiction of the train's front operation area.

[0011] When a group train enters the handover switching area, the handover GCC sends group train handover information to the receiving GCC; the receiving GCC sends authorization-related information to the handover GCC; the handover GCC splices the authorization information calculated within the jurisdiction of this device and the authorization-related information sent by the receiving GCC and sends it to the group train; the group train passes through the handover switching area according to the spliced ​​authorization information.

[0012] Furthermore, the train runs across equipment jurisdictions, including the following three train running modes across equipment jurisdictions:

[0013] The train group plan is the same when handing over the GCC and receiving the GCC;

[0014] The train has a planned following train when handing over to the GCC, but no planned following train when receiving the GCC;

[0015] The train has no planned following train when it is handed over to GCC, but has planned following train when it receives GCC.

[0016] Furthermore, the handover GCC sends group train handover information to the receiving GCC, including:

[0017] The handover GCC determines that the safest front end of the first train in the group has entered the handover switching area. The handover GCC sends the information of the group train closest to the handover boundary to the receiving GCC;

[0018] The handover GCC sends group train handover information, which includes: group train status, train position, group mode, train speed, and train length;

[0019] The handover GCC sends the group train handover status, which includes: the train formation status including the immediately preceding and immediately following trains, the group train plan, the driving permit for the train serving as the first train in the group, the switches included in the driving permit, and the temporary speed limit included in the driving permit; for the following train and the last train in the group, there are no driving permit start and end points, no switches included in the driving permit, and no temporary speed limit included in the driving permit;

[0020] The handover GCC sends the handover switching area interlocking information, which includes: handover switching area section occupancy, section locking information, turnout information, boundary signal information, and section train sequencing.

[0021] Furthermore, the handover GCC sends group train handover information to the receiving GCC, further comprising:

[0022] When the handover GCC determines that the group train has been deregistered from the handover GCC, it stops sending group train handover switching information to the receiving GCC.

[0023] Furthermore, the receiving GCC sends authorization-related information to the handing GCC, including:

[0024] The receiving GCC receives the group train handover information, handover status, and handover switching area interlocking information sent by the handover GCC; the group train completes registration with the receiving GCC and sends the registered train information; the receiving GCC calculates the group train handover information, group train handover status, and handover switching area interlocking information based on the group plan under its jurisdiction, the handover switching area status, and the train information sent by the ATP;

[0025] The receiving GCC sends group train handover information to the handover GCC. The handover information includes: group train status, train position, group mode, train speed, and train length;

[0026] The receiving GCC sends the group train handover status to the handover GCC. The handover status includes: the status of the registered train formation including the immediately preceding and immediately following trains, as well as the group train plan. For unregistered trains, the formation status is not sent.

[0027] Based on the handover zone status information of the receiving GCC, the driving permission is calculated for the first vehicle in the group that is under the jurisdiction of the receiving GCC up to the handover boundary, and an authorization request is sent to the receiving GCC. For the first vehicle in the group under the jurisdiction of the receiving GCC, the driving permission is calculated from the handover boundary to the end length of the driving permission that can be extended by the receiving GCC. Driving permission information is not calculated for the following vehicles and the last vehicle in the group.

[0028] Based on the status information of the handover area under the jurisdiction of the GCC, the temporary speed limit information within the driving permission range of the registered train is calculated. The temporary speed limit information includes: the temporary speed limit starting point, speed limit length and speed limit value; the temporary speed limit information is not calculated for unregistered trains;

[0029] Calculate the line data of registered trains based on the handover zone status information received from the GCC; do not calculate the line data for unregistered trains;

[0030] Send to the receiving GCC the section occupancy, section locking information, turnout information, boundary signal information, and section train sequencing of the transfer switching area under the jurisdiction of the receiving GCC.

[0031] Furthermore, the receiving GCC sends authorization-related information to the handing-over GCC, further comprising:

[0032] The receiving GCC obtains the front vehicle group plan sent by CTC and there is no planned rear vehicle. If it is determined that the rear end of the front vehicle has entered the jurisdiction, it will send a no tight rear vehicle command to the front vehicle.

[0033] Furthermore, the receiving GCC sends authorization-related information to the handing-over GCC, further comprising:

[0034] The GCC receives the group plan of the leading vehicle sent by the CTC and determines that there is a planned following vehicle. If the rear end of the following vehicle enters the jurisdiction, it sends a command to the leading vehicle to form a group with the following vehicle.

[0035] Furthermore, the handover GCC will splice the authorization information calculated within the jurisdiction of the device and the authorization-related information sent by the receiving GCC and send it to the group train, including:

[0036] The handover GCC receives the handover information and handover status of the train entering the jurisdiction of the receiving GCC from the receiving GCC, and sends the handover GCC the marshaling order, driving permit, temporary speed limit and line data calculated by the receiving GCC, which are combined with the handover GCC, to the train entering the jurisdiction of the receiving GCC. When it is the first train in the group, it has a driving permit; when it is the following train in the group or the last train in the group, it has no driving permit.

[0037] The handover GCC continues to send the marshaling order, driving permit, temporary speed limit and line data calculated by the handover GCC to the unregistered train;

[0038] The transferred GCC does not send control information to the train that has left the jurisdiction of the transferred GCC.

[0039] Furthermore, it also includes:

[0068] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0069] like Figure 1 As shown, a method for switching group train operation control rights includes:

[0070] S101: The group train adopts the driving permission information of the corresponding ground equipment according to the equipment jurisdiction area;

[0071] S102: When a group train runs across equipment jurisdictions, a handover zone is determined based on the boundaries between the equipment jurisdictions. Based on the train's direction of travel, the handover zone is the group control center (GCC), which is the ground equipment in the equipment jurisdiction of the train's current operation. The receiving group control center (GCC), which is the ground equipment in the equipment jurisdiction of the train's preceding operation.

[0072] S103, when the group train enters the handover switching area, the handover GCC sends the group train handover information to the receiving GCC; the receiving GCC sends the authorization-related information to the handover GCC; the handover GCC splices the authorization information calculated within the jurisdiction of the device and the authorization-related information sent by the receiving GCC and sends it to the group train; the group train passes through the handover switching area according to the spliced ​​authorization information.

[0073] The specific implementation is as follows:

[0074] In existing CTCS-3 and CTCS-N train control systems, trains operate according to driving permits sent by ground equipment. When traveling within the jurisdiction of ground equipment A, a train accepts the driving permits sent by ground equipment A. When traveling within the jurisdiction of ground equipment B, a train accepts the driving permits sent by ground equipment B. To achieve seamless, non-stop handovers between ground equipment A and B, ground equipment A and B must exchange boundary train information and driving permit information, calculate the driving permit at the interface, and send it to the train. Trains accept the driving permit information from the corresponding ground equipment based on their jurisdiction, enabling handovers between different equipment and completing handovers. Existing train handover technology only supports handovers for a single train at the handover boundary. It cannot support handovers for multiple trains in group formations.

[0075] Schematic diagram Figure 2 As shown in the figure, the CTC sends train group plan information to the handover GCC and the receiving GCC, which is mainly divided into the following operation modes:

[0076] 1) The train group plan is consistent between the handing over GCC and the receiving GCC;

[0077] 2) The train has a planned following train when handing over to the GCC, but no planned following train when receiving the GCC;

[0078] 3) The train has no planned following train when it is handed over to the GCC, but has planned following train when it is received by the GCC.

[0079] Operation mode 1: The train group plan of the handover GCC and the receiving GCC is consistent.

[0080] like Figure 3 As shown, when the group train triggers the handover,

[0081] 1) The handover group control center (GCC) determines that the safe front end of the first train in the group has entered the handover switching area. The handover GCC sends the information of the group train closest to the handover boundary to the receiving group control center (GCC).

[0082] Send group train transfer information: Train group status [ATP1 group lead car, ATP2 group follower car, ATP3 group tail car], train position [ATP1, ATP2, ATP3], group mode [ATP1, ATP2, ATP3], train speed [ATP1, ATP2, ATP3], train length [ATP1, ATP2, ATP3].

[0083] Send group train transfer status: ATP1 marshaling status [no immediate preceding car, immediate following car ATP2], ATP2 marshaling status [immediate preceding car ATP1, immediate following car ATP3], ATP3 marshaling status [immediate preceding car ATP2, no immediate following car], train group plan [ATP1, ATP2, ATP3], train driving permit [ATP1], ATP2 and ATP3 are following cars and tail cars, no driving permit start and end point, switches included in the driving permit [ATP1], temporary speed limit included in the driving permit [ATP1].

[0084] Send transfer switching area interlocking information: transfer switching area section occupancy, section locking information, switch information, boundary signal information, section train sequence [ATP1, ATP2, ATP3].

[0085] 2) The receiving GCC receives the group train handover information, handover status, and handover area interlocking information from the handover GCC. ATP1 registers with the receiving GCC and sends train information. The receiving GCC calculates the group train handover information, group train handover status, and handover area interlocking information based on the handover area status under its jurisdiction and the train information sent by the ATP.

[0086] Send group train handover information to handover GCC: None.

[0087] The group train handover status is sent to the handover GCC: ATP1 marshaling status [no immediate preceding train, immediate following train ATP2], and train group plan [ATP1, ATP2, ATP3]. If ATP2 and ATP3 are not registered with the receiving GCC, the ATP2 and ATP3 marshaling status will not be sent.

[0088] Based on the status of the handover zone under the jurisdiction of the receiving GCC, the ATP1 driving permit is calculated with the starting point as the handover boundary and the length as the receiving GCC's extendable driving permit end length. If ATP2 and ATP3 are not registered with the receiving GCC, ATP2 and ATP3 driving permit information is not calculated.

[0089] The starting point, length, and value of the temporary speed limit within the permitted range of ATP1 are calculated based on the status of the handover zone under the jurisdiction of the receiving GCC. If ATP2 or ATP3 are not registered with the receiving GCC, their temporary speed limit information is not calculated.

[0090] ATP1 line data is calculated based on the handover area status under the receiving GCC. ATP2 and ATP3 line data are not calculated if they are not registered with the receiving GCC.

[0091] Send to the receiving GCC the section occupancy, section locking information, switch information, boundary signal information, and section train sequence of the transfer switching area under the jurisdiction of the receiving GCC [None].

[0092] 3) The Handover GCC receives the ATP1 information and ATP1 status information from the Receiving GCC, and then combines the ATP1 marshaling commands, driving permits (Handover GCC + Receiving GCC), temporary speed limits (Handover GCC + Receiving GCC), and line data (Handover GCC + Receiving GCC) calculated by the Handover GCC and sends them to ATP1. If the Receiving GCC does not send the ATP2 and ATP3 group handover train information and status, it will continue to send the marshaling commands, driving permits (Handover GCC), temporary speed limits (Handover GCC), and line data (Handover GCC) calculated by the Handover GCC to ATP2 and ATP3.

[0093] 4) The receiving GCC sends the marshaling command, driving permission [transfer GCC + receiving GCC], temporary speed limit [transfer GCC + receiving GCC], and line data [transfer GCC + receiving GCC] to group train ATP1 and sends them to ATP1.

[0094] like Figure 4 As shown, when the group train control takes over,

[0095] 1) The handover group control center (GCC) determines that the safe front end of the first train in the group has entered the handover switching area. The handover GCC sends the information of the group train closest to the handover boundary to the receiving group control center (GCC).

[0096] Send group train transfer information: train group status [ATP2 group following car, ATP3 group tail car], train position [ATP2, ATP3], group mode [ATP2, ATP3], train speed [ATP2, ATP3], train length [ATP2, ATP3].

[0097] Send group train transfer status: ATP2 marshaling status [immediate preceding car ATP1, immediate following car ATP3], ATP3 marshaling status [immediate preceding car ATP2, no immediate following car], train group plan [ATP1, ATP2, ATP3], ATP2 and ATP3 are following cars and tail cars, no starting and ending points of the driving permit, no switches included in the driving permit, and no temporary speed limit included in the driving permit.

[0098] Send transfer switching area interlocking information: transfer switching area section occupancy, section locking information, switch information, boundary signal information, section train sequence [ATP2, ATP3].

[0099] 2) The receiving GCC receives the group train handover information, handover status, and handover area interlocking information from the handover GCC. ATP1 registers with the receiving GCC and transmits ATP1 train information. ATP2 registers with the receiving GCC and transmits ATP2 train information. The receiving GCC calculates the group train handover information, group train handover status, and handover area interlocking information based on the handover area status under its jurisdiction and the train information sent by the ATP.

[0100] Send group train handover information to the handover GCC: train group status [ATP1 Group first train], train position [ATP1], group mode [ATP1], train speed [ATP1], train length [ATP1].

[0101] The group train handover status is sent to the handover GCC: ATP1 marshaling status [no immediate preceding train, immediate following train ATP2], ATP2 marshaling status [immediate preceding train ATP1, immediate following train ATP3], and train group plan [ATP1, ATP2, ATP3]. If ATP3 is not registered with the receiving GCC, the ATP3 marshaling status will not be sent.

[0102] Based on the status of the handover zone under the jurisdiction of the receiving GCC, the ATP1 driving permit is calculated with the starting point of the handover boundary and the length of the driving permit end point, which can be extended by the receiving GCC. ATP2 is a following vehicle and its driving permit is not calculated. ATP3 driving permit information is not calculated if it is not registered with the receiving GCC.

[0103] Based on the status of the handover area under the jurisdiction of the receiving GCC, the temporary speed limit starting point, speed limit length, and speed limit value within the driving permission range of ATP1 and ATP2 are calculated. If ATP3 is not registered with the receiving GCC, the ATP3 temporary speed limit information is not calculated.

[0104] Calculate ATP1 and ATP2 line data based on the handover area status under the receiving GCC. If ATP3 is not registered with the receiving GCC, ATP3 line data is not calculated.

[0105] Send the receiving GCC the section occupancy, section locking information, switch information, boundary signal information, and section train sequence [ATP1] of the transfer switching area under the jurisdiction of the receiving GCC.

[0106] 3) The Handover GCC receives the ATP2 group handover train information and ATP2 status information from the Receiving GCC. It then combines the ATP2 marshaling commands calculated by the Handover GCC, indicating that ATP2 is a following train and does not have a driving permit. The Temporary Speed ​​Limit (Handover GCC + Receiving GCC) and Line Data (Handover GCC + Receiving GCC) are sent to ATP2. If the Receiving GCC does not send the ATP3 group handover train information and group handover train status, it will continue to send the marshaling commands calculated by the Handover GCC, the driving permit (Handover GCC), the Temporary Speed ​​Limit (Handover GCC), and the Line Data (Handover GCC) to ATP3. If ATP1 has already left the Handover GCC's jurisdiction, no control information will be sent to ATP1.

[0107] 4) The receiving GCC sends a marshaling command ("No immediate preceding train, immediate following train ATP2"), a driving permit ("Receive GCC"), a temporary speed limit ("Receive GCC"), and line data ("Receive GCC") to group train ATP1. Group train ATP2 sends a marshaling command ("Immediate preceding train ATP1, Immediate following train ATP3"), a driving permit ("Transfer GCC + Receiving GCC"), a temporary speed limit ("Transfer GCC + Receiving GCC"), and line data ("Transfer GCC + Receiving GCC"). Group train ATP3, which has not yet registered a receiving GCC, does not send control information to ATP3.

[0108] like Figure 5 As shown, at the end of the group train transfer,

[0109] 1) When the handover group control center (GCC) determines that ATP1, ATP2, and ATP3 are deregistered from the handover GCC, it stops sending group train handover switching information to the receiving GCC.

[0110] Send group train handover information: train group status [None], train position [None], group mode [None], train speed [None], train length [None].

[0111] Send group train transfer status: marshalling status [None], train group plan [None], driving permit [None].

[0112] Send transfer switching area interlocking information: transfer switching area section occupancy, section locking information, switch information, boundary signal information, section train sequence [none].

[0113] 2) The receiving GCC receives the group train handover information, handover status, and handover area interlocking information from the handover GCC. ATP1 registers with the receiving GCC and transmits ATP1 train information. ATP2 registers with the receiving GCC and transmits ATP2 train information. ATP3 registers with the receiving GCC and transmits ATP3 train information. The receiving GCC calculates the group train handover information, group train handover status, and handover area interlocking information based on the handover area status under its jurisdiction and the train information transmitted by the ATP.

[0114] Send group train handover information to the handover GCC: train group status [ATP1 group lead car, ATP2 group follower car, ATP3 group tail car], train position [ATP1, ATP2, ATP3], group mode [ATP1, ATP2, ATP3], train speed [ATP1, ATP2, ATP3], train length [ATP1, ATP2, ATP3].

[0116] Based on the status of the handover zone under the jurisdiction of the receiving GCC, the ATP1 driving permit is calculated with the starting point of the handover boundary and the length of the driving permit end point, which can be extended by the receiving GCC. ATP2 is the following vehicle and its driving permit is not calculated. ATP3 is the trailing vehicle and its driving permit information is not calculated.

[0117] Based on the information such as the status of the handover area under the jurisdiction of the GCC, the starting point, length and value of the temporary speed limit of ATP1, ATP2 and ATP3 are calculated.

[0118] Calculate the ATP1, ATP2, and ATP3 line data information based on the status of the handover area under the jurisdiction of the receiving GCC.

[0119] Send to the receiving GCC the section occupancy, section locking information, switch information, boundary signal information, and section train sequence [ATP3, ATP2, ATP1] of the transfer switching area under the jurisdiction of the receiving GCC.

[0120] 3) If ATP1, ATP2, and ATP3 have left the area under the jurisdiction of the GCC, no control information will be sent to ATP1, ATP2, and ATP3.

[0121] 4) The receiving GCC sends a marshaling order [No immediate preceding car, immediate following car ATP2], a driving permit [received GCC], a temporary speed limit [received GCC], and line data [received GCC] to group train ATP1. Group train ATP2 sends a marshaling order [Immediate preceding car ATP1, Immediate following car ATP3], a driving permit [received GCC], a temporary speed limit [received GCC], and line data [received GCC]. Group train ATP3 sends a marshaling order [Immediate preceding car ATP2, No immediate following car], a driving permit [received GCC], a temporary speed limit [received GCC], and line data [received GCC].

[0122] Operation mode 2: The train has a planned following train when handing over to the GCC, and no planned following train when receiving the GCC.

[0123] like Figure 6 As shown, when the group train triggers the handover,

[0124] 1) The handover group control center (GCC) determines that the safe front end of the first train in the group has entered the handover switching area. The handover GCC sends the information of the group train closest to the handover boundary to the receiving group control center (GCC).

[0125] Send group train transfer information: Train group status [ATP1 group lead car, ATP2 group follower car, ATP3 group tail car], train position [ATP1, ATP2, ATP3], group mode [ATP1, ATP2, ATP3], train speed [ATP1, ATP2, ATP3], train length [ATP1, ATP2, ATP3].

[0126] Send group train transfer status: ATP1 marshaling status [no immediate preceding car, immediate following car ATP2], ATP2 marshaling status [immediate preceding car ATP1, immediate following car ATP3], ATP3 marshaling status [immediate preceding car ATP2, no immediate following car], train group plan [ATP1, ATP2, ATP3], train driving permit [ATP1], ATP2 and ATP3 are following cars and tail cars, no driving permit start and end point, switches included in the driving permit [ATP1], temporary speed limit included in the driving permit [ATP1].

[0127] Send transfer switching area interlocking information: transfer switching area section occupancy, section locking information, switch information, boundary signal information, section train sequence [ATP1, ATP2, ATP3].

[0128] 2) The receiving GCC receives the group train handover information, handover status, and handover area interlocking information from the handover GCC. ATP1 registers with the receiving GCC and sends train information. The receiving GCC calculates the group train handover information, group train handover status, and handover area interlocking information based on the handover area status under its jurisdiction and the train information sent by the ATP.

[0129] Send group train handover information to handover GCC: None.

[0130] The group train handover status is sent to the handover GCC: ATP1 marshaling status [no immediate preceding train, immediate following train ATP2], and train group plan [ATP1, ATP2, ATP3]. If ATP2 and ATP3 are not registered with the receiving GCC, the ATP2 and ATP3 marshaling status will not be sent.

[0131] Based on the status of the handover zone under the jurisdiction of the receiving GCC, the ATP1 driving permit is calculated with the starting point as the handover boundary and the length as the receiving GCC's extendable driving permit end length. If ATP2 and ATP3 are not registered with the receiving GCC, ATP2 and ATP3 driving permit information is not calculated.
