Description

Technical Field

[0001] This invention relates to the field of train scheduling, specifically to a method for automatically changing the planned entry and exit points of trains at one station with three yards. Background Technology

[0002] A special type of station exists in CTC3.0 railways. While managed as a single station at the railway bureau's dispatching and command center level, it actually corresponds to three train yards, each requiring separate train arrival and departure operations. The prerequisite for CTC3.0 stations to automatically manage train routes is "precise planning of train entrances / exits and tracks." In this special station type with one station and three yards, the initial train entrances / exits in the dispatching and command center are fixed by default, and the train's route through the three yards is generally arranged by the station's planning duty officer.

[0003] Currently, in CTC3.0 stations with multiple yards, the planned entrances and exits and tracks for trains are manually designated by the station planning duty officer. When the station planning duty officer changes the receiving track from yard I to yard III, the change in the receiving yard causes the previously planned entrance to be disconnected from yard III, requiring the station planning duty officer to manually correct the planned entrance. The above usage scenario carries the risk of incorrect or missed planned entrances and exits, which can easily cause traffic safety hazards.

[0004] In summary, the current system has the following shortcomings:

[0005] When the train arrival track of a station with one station and three platforms changes, the entrance needs to be manually modified, which carries the risk of errors and omissions. When the train departure track of a station with one station and three platforms changes, the exit needs to be manually modified, which also carries the risk of errors and omissions. The entrance and exit of the train plan of a station with one station and three platforms does not have the function of automatic modification. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that when the departure or receiving track of a train plan changes in a station with three yards, the corresponding entrance or exit does not have the function of automatic change, which easily leads to station planning duty officers making mistakes or omitting entrances and exits.

[0007] To achieve the above objectives, this invention proposes a method for automatically changing the planned entrances and exits of trains at one station with three yards, comprising the following steps:

[0008] S1. After receiving the train plan from the dispatch center, determine whether the depot and track have been arranged; if the depot and track have been arranged, proceed to step S2.

[0009] S2. After determining the arranged depot and tracks, determine whether the planned passageway can connect with the arranged depot and tracks; if the planned passageway cannot connect with the arranged depot and tracks, proceed to step S3.

[0010] S3. If the planned passageway for the train cannot connect with the arranged depot and track, determine whether there are other passageways connecting the adjacent stations in the direction of train travel to the arranged depot and track; if there are other passageways connecting the adjacent stations in the direction of train travel to the arranged depot and track, proceed to step S4.

[0011] S4. When there are other access points at adjacent stations in the direction of train travel that connect to the arranged depot and tracks, the planned access point for the train will be changed to another access point at an adjacent station in the direction of train travel that connects to the arranged depot and tracks.

[0012] In step S1, after receiving the train plan issued by the dispatch center, the station planning duty officer arranges the train yard and track for the train.

[0013] The train plan includes a passageway. When the train plan is a termination or arrival plan, the passageway is the entrance, the track is the receiving track, and the adjacent station in the direction of train travel is the preceding station. When the train plan is a departure or handover plan, the passageway is the exit, the track is the departure track, and the adjacent station in the direction of train travel is the following station.

[0014] In step S1, if it is determined that no train yard or track has been arranged, the station planning duty officer is prompted to arrange a train yard and track for the train.

[0015] In step S2, if the planned passageway of the train can be connected to the arranged depot and track, then proceed to step S5: determine whether the track meets the requirements of the station inspection.

[0016] Step S5 further includes the following cases:

[0017] S51. When the track meets the requirements of the station inspection, the existing arrangement of the access points, parking lots and tracks shall remain unchanged.

[0018] S52. If the track does not meet the requirements of the detailed inspection, the prompt will be: Track arrangement error.

[0019] In case S52, it is further indicated that the currently arranged track does not meet the requirements of the station inspection and the track needs to be rearranged.

[0020] The detailed station inspections include: if the train is an oversized vehicle, whether the track can accommodate it; if the train is an electric traction train, whether the track is connected to the grid and energized; if the train has passenger service, whether the track has a platform; if the train needs water supply, whether the track has water supply equipment; if the train needs sewage suction, whether the track has sewage suction equipment; if the train is a military vehicle, whether the track can accommodate it; if the train is a freight vehicle, whether the track can accommodate it; whether the train's passenger and freight attributes meet the requirements for receiving vehicles at the entrance / exit; if the train is an oversized vehicle, whether the entrance / exit can accommodate it; whether the entrance / exit allows oversized vehicles to pass each other in the designated area; and whether the turnout numbers on the train's route meet the train's attribute requirements.

[0021] In step S3, if it is determined that there are no other passageways connecting the adjacent station in the direction of train travel to the arranged depot and tracks, a track arrangement error is indicated, and the tracks need to be rearranged.

[0022] Step S3 further includes the following steps:

[0023] S31. Determine whether there are any passageways other than the planned passageway at the adjacent station in the direction of train travel; if so, proceed to step S32.

[0024] S32. Determine whether other passageways in the adjacent stations along the train's direction of travel, excluding the planned passageway, are connected to the arranged depot and tracks; if connected, proceed to step S4.

[0025] In step S31, if there is no passageway other than the planned passageway at the adjacent station in the direction of train travel, a track arrangement error is indicated, indicating that the track and passageway are not connected and the track needs to be rearranged.

[0026] In step S32, if none of the passageways in the adjacent stations along the train's direction of travel, except for the passageways planned for the train, are connected to the arranged depot and tracks, a track arrangement error is indicated, and the tracks are not connected to the passageways in the adjacent stations along the train's direction of travel, requiring a track rearrangement.

[0027] In step S4, if there are other passageways connecting the adjacent station in the direction of train travel to the arranged depot and track, it is determined whether the track meets the requirements of the station inspection.

[0028] In step S4, when determining whether the track meets the requirements of the detailed station inspection, the following situations are further included:

[0029] S41. If the stock track does not meet the requirements of the detailed station check, it will indicate that the stock track arrangement is incorrect and does not meet the detailed station requirements. The stock track needs to be rearranged.

[0030] S42. If the track meets the requirements of the station inspection, the planned access point for the train will be changed to another access point of an adjacent station in the direction of train travel that is connected to the arranged depot and track.

[0031] In step S1, after prompting the station planning duty officer to arrange the train yard and track, the station will re-evaluate whether the train yard and track have been arranged.

[0032] If there are multiple other access points in adjacent stations along the train's direction of travel that connect to the arranged depot and tracks, then process S32-S4 is executed for each access point until an access point that connects to the arranged depot and tracks and meets the requirements of the station detailed inspection is found and the access point change is completed, or a track arrangement error is indicated.

[0033] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0034] When the planned train receiving track of a station with one station and three yards changes, and the track is no longer connected to the original planned yard entrance, the planned entrance of the station will be automatically changed to prevent incorrect entrances.

[0035] When the planned train departure track of a station with one station and three yards changes, and the track is no longer connected to the originally planned station exit, the planned exit of the station will be automatically changed to prevent incorrect exits.

[0036] It improved the work efficiency of the station's planning staff and enhanced the automation level of the station system. Attached Figure Description

[0042] The present invention discloses a method for automatically changing the entrance of a train plan in a station with three yards. This method can be used to automatically change the passageway in the train plan during both receiving and departure scenarios. During receiving, the track assigned to the train is the receiving track, the passageway is the entrance, and the adjacent station in the train's direction of travel is the preceding station. During departure, the track assigned to the train is the departure track, the passageway is the exit, and the adjacent station in the train's direction of travel is the following station. The invention will now be described through two specific embodiments.

[0043] This embodiment discloses a method for automatically changing the train schedule entry point for a station with three yards, such as... Figure 1 As shown, it includes the following steps:

[0044] S1. After receiving the train plan from the dispatch center, the station planning duty officer arranges the train yard and receiving track. The system determines whether the train yard and receiving track have been arranged. If the train yard and receiving track have been arranged, proceed to step S2.

[0045] In this embodiment, the station planning duty officer arranges the train yard I and the receiving track I_3G for the train.

[0046] The train plan is either a destination or arrival plan, and the train plan includes the station entrance. For example, in this embodiment, the planned train's entrance is entrance B. After receiving the train plan, the station planning officer arranges a receiving track for the train.

[0047] If the system determines that no train yard and receiving track have been arranged, it will prompt the station planning officer to arrange a train yard and receiving track for the train. After the prompt, it will re-determine whether a train yard and receiving track have been arranged.

[0048] S2. After determining the arranged depot and receiving track, determine whether the planned entrance of the train can be connected to the arranged depot and receiving track.

[0049] If the planned entrance B of the train cannot be connected to the arranged depot I and receiving track I_3G, then proceed to step S3; if the planned entrance B of the train can be connected to the arranged depot I and receiving track I_3G, then proceed to step S5.

[0050] S3. When the planned entrance of the train cannot be connected to the arranged depot and receiving track, determine whether there are other entrances at the next station that are connected to the arranged depot and receiving track.

[0051] In this context, the "forward station" refers to the station corresponding to the entrance, which is also the adjacent station ahead in the direction of train travel. In this embodiment, the forward station is station A.

[0052] When the planned entrance B of the train cannot connect with the train yard I and receiving track I_3G arranged by the station duty officer, it is necessary to determine whether the station A corresponding to entrance B has other entrances that can connect with the train yard I and receiving track I_3G.

[0053] If it is determined that there are no other entrances to the station ahead (Station A) that connect to the arranged depot I and receiving track I_3G, then a message will be sent indicating that track I_3G is incorrectly arranged and needs to be rearranged; if it is determined that there are other entrances to the station ahead (Station A) that connect to the arranged depot I and receiving track I_3G, then proceed to step S4.

[0054] The specific steps for determining whether the preceding station A has other entrances that connect to the arranged parking lot I and receiving track I_3G include:

[0055] S31. Determine whether there is any other entrance besides the planned entrance B at the next station (A).

[0056] If it exists, proceed to step S32;

[0057] If it does not exist, the station planning duty officer will be prompted that the track arrangement is incorrect; and further prompted that the receiving track I_3G is not connected to the entrance and the track needs to be rearranged.

[0058] S32. Determine whether the other entrances in the forward station A, other than the planned entrance B, are connected to the arranged depot I and receiving track I_3G; In this embodiment, the other entrances in the forward station A, other than the planned entrance B, are entrances A;

[0059] If entrance A is connected to the arranged parking lot I and receiving track I_3G, then proceed to step S4;

[0060] If entrance A is not connected to the arranged depot I and receiving track I_3G, the station planning officer will be notified that the track arrangement is incorrect; and further prompted that receiving track I_3G is not connected to any entrances in the station ahead, and the track arrangement needs to be rearranged.

[0061] S4. When there are other entrances at the preceding station that connect to the arranged depot and receiving track, and the receiving track meets the station detail inspection requirements, the planned entrance for the train will be changed to another entrance at the preceding station that connects to the arranged depot and receiving track.

[0062] Specifically, when the preceding station A has another entrance (in this embodiment, entrance A) that connects to the arranged parking lot I and receiving track I_3G, it is determined whether receiving track I_3G meets the requirements of the station detail inspection, including the following situations:

[0063] S41. If the receiving track I_3G does not meet the requirements of the station detail inspection, the station planning duty officer will be notified that the track arrangement is incorrect and the receiving track I_3G does not meet the station detail requirements. The track needs to be rearranged.

[0064] S42. If the receiving track I_3G meets the requirements of the station detailed inspection, then the planned entrance B of the train will be changed to the entrance A of the station ahead.

[0065] The detailed station inspections include: if the train is an oversized vehicle, whether the track can accommodate it; if the train is an electric traction train, whether the track is connected to the grid and energized; if the train has passenger service, whether the track has a platform; if the train needs water supply, whether the track has water supply equipment; if the train needs sewage suction, whether the track has sewage suction equipment; if the train is a military vehicle, whether the track can accommodate it; if the train is a freight vehicle, whether the track can accommodate it; whether the train's passenger and freight attributes meet the requirements for receiving vehicles at the entrance / exit; if the train is an oversized vehicle, whether the entrance / exit can accommodate it; whether the entrance / exit allows oversized vehicles to pass each other in the designated area; and whether the turnout numbers on the train's route meet the train's attribute requirements.

[0066] If there are multiple entrances other than the planned entrance B at the preceding station A, then process S32-S4 is executed for each entrance until an entrance is found that connects to the arranged depot I and receiving track I_3G and makes receiving track I_3G meet the station detail inspection requirements, and the entrance change is completed. Alternatively, after judging each entrance, the following prompts are made: Track arrangement error, receiving track I_3G is not connected to any entrances in the preceding station, and the track needs to be rearranged. Or, the following prompts are made: Track arrangement error, receiving track I_3G does not meet the station detail requirements, and the track needs to be rearranged.

[0067] In step S2, if the planned entrance B of the train can connect with the arranged depot I and receiving track I_3G, then step S5 will be executed: determine whether receiving track I_3G meets the requirements of the station inspection, and further include the following situations:

[0068] S51. When the receiving track I_3G meets the requirements of the station detailed inspection, the existing arrangement of entrance B, yard I and receiving track I_3G shall remain unchanged.

[0069] S52. When the receiving track I_3G does not meet the requirements of the station detailed inspection, the system prompts the station planning duty officer: the track arrangement is incorrect, and further prompts: the currently arranged receiving track I_3G does not meet the requirements of the station detailed inspection and the track needs to be rearranged.

[0070] The present invention also discloses another embodiment, a method for automatically changing the planned exit of a train at a station with three yards, such as... Figure 2 As shown, it includes the following steps:

[0071] S1. After receiving the train plan from the dispatch center, the station planning duty officer arranges the train yard and departure track. The system determines whether the train yard and departure track have been arranged. If the train yard and departure track have been arranged, proceed to step S2.

[0072] In this embodiment, the station planning duty officer assigns the train yard V and departure track V_5G.

[0073] The train plan is either a departure or delivery plan, and the train plan includes the station's exit. For example, in this embodiment, the exit of the planned train is exit C. After receiving the train plan, the station planning officer arranges the departure track for the train.

[0074] If the system determines that no train yard and departure track have been arranged, it will prompt the station planning officer to arrange the train yard and departure track. After the prompt, it will re-determine whether the train yard and departure track have been arranged.

[0075] S2. After determining the arranged depot and departure track, determine whether the planned exit of the train can be connected to the arranged depot and departure track;

[0076] If the planned exit C of the train cannot be connected to the arranged depot V and departure track V_5G, proceed to step S3; if the planned exit C of the train can be connected to the arranged depot V and departure track V_5G, proceed to step S5.

[0077] S3. When the planned exit of the train cannot be connected to the arranged depot and departure track, determine whether there are other exits at the rear station that are connected to the arranged depot and departure track.

[0078] Here, the rear station refers to the station corresponding to the exit, which is also the adjacent station behind the train in the direction of travel. In this embodiment, the rear station is station B.

[0079] When the planned exit C of the train cannot be connected to the train yard V and departure track V_5G arranged by the station's duty officer, it is necessary to determine whether the station B corresponding to exit C has other exits that can be connected to the train yard V and departure track V_5G.

[0080] If it is determined that there are no other exits at the rear station B that connect to the arranged depot V and departure track V_5G, then a message will be sent indicating that track V_5G is incorrectly arranged and needs to be rearranged; if it is determined that there are other exits at the rear station B that connect to the arranged depot V and departure track V_5G, then proceed to step S4.

[0081] The specific steps for determining whether station B has other exits connected to the arranged depot V and departure track V_5G include:

[0082] S31. Determine whether station B behind the train has any other exit besides exit C in the train's plan.

[0083] If it exists, proceed to step S32;

[0084] If it does not exist, the station planning officer will be notified that the track arrangement is incorrect; and further prompted that track V_5G is not connected to the exit and the track needs to be rearranged.

[0085] S32. Determine whether the exits of the rear station B other than the planned exit C are connected to the arranged depot V and departure track V_5G; In this embodiment, the exits of the rear station B other than the planned exit C are exits D;

[0086] If exit D is connected to the arranged parking lot V and departure track V_5G, then proceed to step S4;

[0087] If exit D is not connected to the arranged depot V and departure track V_5G, the station planning officer will be notified that the track arrangement is incorrect; and further prompted that track V_5G is not connected to any exits in the following station and the track needs to be rearranged.

[0088] S4. When there are other exits at the rear station that are connected to the arranged train yard and departure track, and the departure track meets the requirements of the station inspection, the planned exit of the train will be changed to another exit of the front station that is connected to the arranged train yard and departure track.

[0089] Specifically, when the rear station B has another exit (in this embodiment, exit D) that connects to the arranged depot V and departure track V_5G, it is determined whether departure track V_5G meets the requirements of the station detailed inspection, including the following situations:

[0090] S41. If the departure track V_5G does not meet the requirements of the station detail check, the station planning duty officer will be notified that the track arrangement is incorrect and the departure track V_5G does not meet the station detail requirements. The track needs to be rearranged.

[0091] S42. If the departure track V_5G meets the requirements of the station inspection, then the planned exit C of the train will be changed to the exit D of the station ahead.

[0092] In step S2, if the planned exit C of the train can connect with the arranged depot V and departure track V_5G, then step S5 will be executed: determine whether departure track V_5G meets the requirements of the station detail inspection, and further include the following situations:

[0093] S51. When the departure track V_5G meets the requirements of the station detailed inspection, the existing arrangement of exit C, yard V and departure track V_5G shall remain unchanged.

[0094] S52. When the departure track V_5G does not meet the requirements of the station detailed inspection, the system prompts the station planning duty officer: the track arrangement is incorrect, and further prompts: the currently arranged departure track V_5G does not meet the requirements of the station detailed inspection and the track needs to be rearranged.

[0095] If there are multiple exits other than the planned exit C at the rear station B, then process S32-S4 is executed for each exit until an exit is found that connects to the arranged depot V and departure track V_5G and makes departure track V_5G meet the station detail check requirements, and the exit change is completed. Alternatively, after judging each exit, the following prompts are made: Track arrangement error, departure track V_5G is not connected to any exits in the rear station, and the track needs to be rearranged. Or, the following prompts are made: Track arrangement error, departure track V_5G does not meet the station detail requirements, and the track needs to be rearranged.

[0096] Although the present invention has been described in detail through the preferred embodiments above, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
