A method and system for determining turnout occupancy and locking

Abstract

This invention relates to a method and system for determining turnout occupancy and locking, belonging to the field of turnout occupancy and locking control technology. The method includes: an OC device detecting the section status of a turnout section and sending it to an administrator device; the administrator device acquiring the section status of the turnout area, determining the turnout occupancy status based on the received section status, and sending the turnout occupancy status to the OC device; the OC device continuously detecting the section status and receiving the turnout occupancy status to update the turnout occupancy and locking status. When the section status changes from cleared to occupied, the turnout occupancy and locking status is activated, and the system determines whether to update the turnout occupancy and locking status based on the turnout occupancy status. This ensures that when a train with no available space unexpectedly enters the turnout section, the lock status of the turnout remains active from the moment the OC device detects the turnout section as occupied, preventing a situation where the turnout can move after a train with no available space unexpectedly enters the turnout area.

Description

Technical Field

[0001] This invention relates to the field of turnout occupancy and locking control technology, specifically to a turnout occupancy and locking judgment method and system. Background Technology

[0002] In a train autonomous operation system employing a distributed resource processing approach, unlike the traditional method of determining turnout occupancy lock activation based on whether the turnout section is occupied, the administrator device determines turnout occupancy based on whether there is a train in the turnout area, and then sends the turnout occupancy status to the OC device (Object Controller). When the turnout is occupied, the OC device determines that the turnout occupancy lock is activated; when the turnout is not occupied, the OC device determines that the turnout occupancy lock is not activated. Devices that need to control turnout movement, such as the administrator device, determine whether the turnout can be moved based on the turnout occupancy lock status obtained from the OC device. When the turnout occupancy lock is activated, the turnout cannot be moved; when the turnout occupancy lock is not activated, the turnout can be moved if other conditions are met.

[0003] When a train without a designated position (a train whose location cannot be precisely determined, such as a lost train, a train that has lost communication with the administrator, or an engineering vehicle, whose position is determined by the occupancy of the section) is present in an adjacent section of the turnout section, and this train moves unexpectedly (e.g., slips) into the turnout section, the OC (Operating Center) device detects the occupancy of the turnout section and reports the occupancy status to the administrator device. Since the turnout section was previously cleared and there are no trains in the turnout area, the administrator device reports the turnout as unoccupied to the OC device. That is, the OC device receives the administrator's report of unoccupied turnout status at this time. Due to communication delays, in the worst-case scenario, during the two time periods after the train without a designated position occupies the turnout section, either when the administrator device has not received the section status report from the OC device, or when the OC device has not received the turnout occupancy status report from the administrator device, the OC device still considers the turnout occupancy lock not activated. During this time, the administrator device obtains the turnout occupancy lock status from the OC device as inactive and can control the turnout movement. This results in a situation where a train without a designated position is in the turnout area, but the turnout can still move.

[0004] It is evident that in a communication-based distributed system, OC devices are allowed to use relatively "old" and not immediately updated information for a certain period of time. For example, if the OC device uses relatively "old" turnout occupancy information, it may cause train derailment or conflict with other trains, posing a serious risk to the safe operation of the train autonomous operation system. Summary of the Invention

[0005] In view of the shortcomings of the related technologies, the purpose of this invention is to provide a turnout occupancy and locking judgment method and system to solve the problem that the turnout can still move when a train with no position moves unexpectedly to the turnout area, thereby mitigating the safety risks such as train derailment or turnout squeeze that may be caused by this problem.

[0006] This invention provides a method for determining turnout occupancy and locking, comprising the following steps:

[0007] Section status acquisition steps: The OC device detects the section status of the turnout section and sends the section status to the administrator device;

[0008] Steps for obtaining turnout occupancy status: The administrator device obtains the area status of the turnout area. When the area status indicates that there is a train in the turnout area, the turnout occupancy status is determined to be that the turnout is occupied. Otherwise, the turnout occupancy status is determined by the area status and the received section status, and the turnout occupancy status is sent to the OC device.

[0009] The turnout occupancy and locking status determination steps are as follows: The OC device detects the section status in real time and receives the turnout occupancy status to update the turnout occupancy and locking status. When the section status changes from cleared to occupied, the turnout occupancy and locking status is activated, and the device determines whether to update the turnout occupancy and locking status based on the turnout occupancy status.

[0010] In this embodiment of the invention, when the OC device detects that the section status of the turnout has changed from cleared to occupied, the turnout occupancy locking state is activated. Based on the turnout occupancy status received from the administrator device, it is determined whether to update the turnout occupancy locking state. This ensures that when a train with no available space unexpectedly enters the turnout section, the turnout occupancy locking state remains activated from the moment the OC device detects that the turnout section is occupied, preventing the turnout from being able to move after a train with no available space unexpectedly enters the turnout area.

[0011] In some embodiments of the present invention, the step of obtaining the turnout occupancy status specifically includes:

[0012] First state determination step: When the state of the area is that there is a train in the turnout area, then the turnout occupancy state is determined to be turnout occupancy.

[0013] Second state judgment step: When the state of the area is no train in the turnout area and the state of the section is cleared, then the state of the turnout occupancy is judged to be turnout cleared and section cleared.

[0014] The third state determination step: When the state of the area is no train in the turnout area and the state of the section is occupied, then the state of the turnout occupancy is the turnout cleared section occupancy.

[0015] The step of determining the occupancy and locking status of the turnout further includes:

[0016] Section status judgment steps: When the section status changes from cleared to occupied, the turnout occupancy lock status is activated, and it is determined whether to update the turnout occupancy lock status based on the turnout occupancy status, and then the turnout occupancy status judgment steps are entered.

[0017] Otherwise, the turnout occupancy and locking status is not updated, and the turnout occupancy and locking status is determined based on the turnout occupancy status, and the turnout occupancy status determination step is entered.

[0018] The turnout occupancy status determination step further includes:

[0019] When the turnout occupancy status is "turnout occupied", then update the turnout occupancy lockout status to "activated".

[0020] When the turnout occupancy status is "turnout cleared section occupied", then the turnout occupancy locking status is updated to "inactive".

[0021] When the turnout occupancy status is when the turnout clearing section is cleared, and the section status is cleared, then the turnout occupancy locking status is updated to inactive.

[0022] When the turnout occupancy status is when the turnout clearing section is cleared, and the section status is occupied, the turnout occupancy and locking status will not be updated.

[0023] If, after the section status changes to occupied, the administrator device does not receive the section status sent by the OC device and determines that the turnout occupancy status is cleared and the section is cleared, then...

[0024] Alternatively, if the OC device does not receive the turnout occupancy status sent by the administrator device and considers the turnout occupancy status to be that the turnout clearing section is cleared, the OC device will not update the turnout occupancy locking status according to the turnout occupancy status.

[0025] This invention, in its embodiment, activates the turnout occupancy locking state when the OC device detects that the section status has changed from cleared to occupied. It then determines whether to update the turnout occupancy locking state based on the turnout occupancy status. Conversely, when the OC device's section status changes from cleared to occupied and the turnout occupancy status is cleared, the turnout occupancy locking state is not updated. This mitigates the safety risk of turnouts being movable after a train with no available position unexpectedly enters the turnout area in a train autonomous operation system employing distributed resource processing.

[0026] Some embodiments of the present invention further provide a turnout occupancy locking determination system, comprising:

[0027] Section Status Acquisition Module: The OC device detects the section status of the turnout section and sends the section status to the administrator device;

[0028] Turnout Occupancy Status Acquisition Module: The administrator device acquires the area status of the turnout area. When the area status indicates that there is a train in the turnout area, the turnout occupancy status is determined to be that the turnout is occupied. Otherwise, the turnout occupancy status is determined by the area status and the received section status, and the turnout occupancy status is sent to the OC device.

[0029] The turnout occupancy and locking status judgment module: The OC device detects the section status in real time and receives the turnout occupancy status to update the turnout occupancy and locking status. When the section status changes from cleared to occupied, the turnout occupancy and locking status is activated, and the module determines whether to update the turnout occupancy and locking status based on the turnout occupancy status.

[0030] Specifically, the turnout occupancy status acquisition module is as follows:

[0031] First state judgment unit: When the state of the area is that there is a train in the turnout area, the turnout occupancy state is judged to be that the turnout is occupied.

[0032] Second state judgment unit: When the state of the area is no train in the turnout area and the state of the section is cleared, the turnout occupancy state is judged to be turnout cleared and section cleared.

[0033] Third state judgment unit: When the area state is no train in the turnout area and the section state is occupied, the turnout occupancy state is turnout cleared section occupied.

[0034] The turnout occupancy and locking status determination module further includes:

[0035] Section status judgment unit: When the section status changes from cleared to occupied, the turnout occupancy lock status is activated, and the turnout occupancy lock status is determined according to the turnout occupancy status, and then the turnout occupancy status judgment unit is entered.

[0036] Otherwise, the turnout occupancy and locking status is not updated, and the turnout occupancy and locking status is determined based on the turnout occupancy status, and the turnout occupancy status determination unit is entered.

[0037] The turnout occupancy status determination unit further includes:

[0038] When the turnout occupancy status is "turnout occupied", then update the turnout occupancy lockout status to "activated".

[0039] When the turnout occupancy status is "turnout cleared section occupied", then the turnout occupancy locking status is updated to "inactive".

[0040] When the turnout occupancy status is when the turnout clearing section is cleared, and the section status is cleared, then the turnout occupancy locking status is updated to inactive.

[0041] When the turnout occupancy status is when the turnout clearing section is cleared, and the section status is occupied, the turnout occupancy and locking status will not be updated.

[0042] If, after the section status changes to occupied, the administrator device does not receive the section status sent by the OC device and determines that the turnout occupancy status is cleared and the section is cleared, then...

[0043] Alternatively, if the OC device does not receive the turnout occupancy status sent by the administrator device and considers the turnout occupancy status to be that the turnout clearing section is cleared, the OC device will not update the turnout occupancy locking status according to the turnout occupancy status.

[0044] In this embodiment of the invention, when the OC device detects that the section status changes from cleared to occupied, the turnout occupancy locking state is activated, and then the turnout occupancy status is determined to determine whether to update the turnout occupancy locking state based on the turnout occupancy status. However, when the OC device changes the section status from cleared to occupied and the turnout occupancy status is turnout cleared and section cleared, the turnout occupancy locking state is not updated. This prevents the situation where a turnout can move after an unpositioned train unexpectedly enters the turnout area, thus mitigating the safety risk of the turnout being able to move after an unpositioned train unexpectedly enters the turnout area in a train autonomous operation system using a distributed resource processing method.

[0056] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0057] The technical solution of the present invention will be described in detail below with reference to specific embodiments and accompanying drawings.

[0058] As attached Figure 1 As shown, the present invention provides a method for determining turnout occupancy and locking, comprising the following steps:

[0059] Section status acquisition step S1: The OC device detects the section status of the turnout section and sends the section status to the administrator device;

[0060] Step S2 for obtaining turnout occupancy status: The administrator device obtains the area status of the turnout area. When the area status is that there is a train in the turnout area, the turnout occupancy status is determined to be that the turnout is occupied. Otherwise, the turnout occupancy status is determined by the area status and the received section status, and the turnout occupancy status is sent to the OC device.

[0061] Among them, combined with the appendix Figure 2-3 As shown, step S2 for obtaining the turnout occupancy status is as follows:

[0062] First state judgment step S21: When the area state is that there is a train in the turnout area, then the turnout occupancy state is judged to be turnout occupancy.

[0063] Second state judgment step S22: When the area state is no train in the turnout area and the section state is cleared, the turnout occupancy state is judged to be turnout cleared and section cleared.

[0064] Third state judgment step S23: When the area state is no train in the turnout area and the section state is occupied, the turnout occupancy state is turnout cleared section occupancy.

[0065] Step S3 for judging the occupancy and locking status of turnouts: The OC device detects the section status in real time and receives the turnout occupancy status to update the turnout occupancy and locking status. When the section status changes from cleared to occupied, the turnout occupancy and locking status is activated, and it is determined whether to update the turnout occupancy and locking status based on the turnout occupancy status.

[0066] Among them, combined with the appendix Figure 4-6 As shown, step S3 for determining the occupancy and locking status of the turnout further includes:

[0067] Section status judgment step S31: When the section status changes from cleared to occupied, the turnout occupancy lockout status is activated, and it is determined whether to update the turnout occupancy lockout status based on the turnout occupancy status, and then proceed to the turnout occupancy status judgment step S32.

[0068] Otherwise, the turnout occupancy and locking status is not updated, and the turnout occupancy and locking status is determined based on the turnout occupancy status, and the turnout occupancy status determination step S32 is entered.

[0069] Among them, the turnout occupancy status determination step S32:

[0070] When the turnout occupancy status is "turnout occupied", then update the turnout occupancy lockout status to "activated".

[0071] When the turnout occupancy status is "turnout cleared section occupied", then the turnout occupancy locking status is updated to "inactive".

[0072] When the turnout occupancy status is when the turnout clearing section is cleared, and the section status is cleared, then the turnout occupancy locking status is updated to inactive.

[0073] When the turnout occupancy status is "turnout cleared section cleared" and the section status is "occupied", the turnout occupancy and locking status will not be updated.

[0074] If, after the section status changes to occupied, the administrator device does not receive the section status sent by the OC device and determines that the turnout occupancy status is cleared and the section is cleared, then...

[0075] Alternatively, if the OC device does not receive the turnout occupancy status sent by the administrator device and considers the turnout occupancy status to be that the turnout clearing section is cleared, the OC device will not update the turnout occupancy locking status according to the turnout occupancy status.

[0076] Using the above method, when the OC device detects that the section status changes from cleared to occupied, the turnout occupancy lock status is activated, and then the turnout occupancy status is determined to decide whether to update the turnout occupancy lock status based on the turnout occupancy status. However, when the OC device's section status changes from cleared to occupied and the turnout occupancy status is turnout cleared and section cleared, the turnout occupancy lock status is not updated. That is, the turnout occupancy lock status is only updated using the turnout occupancy status sent by the administrator when the section status is cleared or the section status is occupied and the administrator reports that the turnout occupancy status is turnout occupied. This mitigates the safety risk that the turnout can move after a train with no position unexpectedly enters the turnout area in the train autonomous operation system using the distributed resource processing method.

[0077] Preferably, in conjunction with the appendix Figure 6 As shown, when a train with no position unexpectedly enters the turnout area and the turnout is locked, the process of the turnout being unable to move is as follows:

[0078] S601: Before a train with no position unexpectedly enters turnout section GC1 from turnout section G1, the OC device detects that turnout section GC1 is cleared, that is, the section status is cleared; the administrator device reports the turnout occupancy status of turnout area P1 as turnout cleared and section cleared; the OC device determines that the turnout occupancy and locking status of turnout section P1 is not activated.

[0079] S602: When a train with no position unexpectedly enters turnout section GC1 from turnout section G1, and the OC device detects that the section status of turnout section GC1 has changed from cleared to occupied, the OC device determines that the turnout occupancy locking status of turnout area P1 is active. At this time, if the administrator device has not yet received the section status of turnout section GC1 from the OC device, the OC device still uses the turnout occupancy status of turnout area P1 reported by the administrator device as turnout cleared section cleared. Since the section status of turnout section GC1 is occupied but the status received from the administrator device is turnout cleared section cleared, the OC device does not update the turnout occupancy locking status according to the turnout occupancy status reported by the administrator device. The turnout occupancy locking status of turnout area P1 remains unchanged, and the turnout occupancy locking status is still active.

[0080] S603: After the administrator device receives a report from the OC device that the section status of turnout section GC1 is occupied, the position of the train with no position extends to the turnout section. The administrator device reports that the turnout occupancy status of turnout area P1 is occupied. However, due to communication delay or data packet loss, the OC device still uses the turnout occupancy status reported by the administrator device last time: the turnout clearing section of turnout area P1 is cleared. Since the section status of turnout section GC1 is occupied while the turnout occupancy status reported by the administrator device is cleared, the OC device does not update the turnout occupancy locking status according to the turnout occupancy status reported by the administrator device. The turnout occupancy locking status of turnout area P1 remains unchanged and is still active.

[0081] S604: Before the administrator device receives a communication interruption regarding the section status of turnout section GC1 from the OC device, and before the OC device receives a communication interruption regarding the turnout occupancy status reported by the administrator device, the OC device receives a report from the administrator device that the turnout occupancy status of turnout area P1 is turnout occupied, and the OC device updates the turnout occupancy locking status of the turnout area to active based on the turnout occupancy status reported by the administrator device.

[0082] During the above process, when a train with no available position unexpectedly enters the turnout section, the OC device detects that the section status of the turnout section is occupied from the start. The turnout occupancy and locking status of the turnout area remains active at all times, and there will be no situation where the turnout can be moved after a train with no available position unexpectedly enters the turnout area.

[0083] Preferably, in conjunction with the appendix Figure 7 As shown, when there is no train on turnout section GC1, the turnout section is fault-occupied, meaning the OC equipment detects that the section status of turnout section GC1 is occupied. When there is no train in the turnout area, the process of moving the turnout is as follows:

[0084] S701: Before the fault occupancy of turnout section GC1, the OC device detected that the section status of turnout section GC1 was cleared; the administrator device reported that the turnout occupancy status of turnout area P1 was cleared and the section was cleared; the OC device determined that the turnout occupancy locking status of turnout P1 was not activated.

[0085] S702: When turnout section GC1 is faultily occupied, the OC device detects that the section status of turnout section GC1 has changed from cleared to occupied, and the OC device determines that the turnout occupancy lock status of turnout P1 is active; if the administrator device has not yet received the turnout section status of GC1 from the OC device, the turnout occupancy status of turnout area P1 reported by the administrator device is turnout cleared section cleared; since the section status of turnout section GC1 is occupied but the turnout occupancy status received from the administrator is turnout cleared section cleared, the OC device does not update the turnout occupancy lock status according to the turnout occupancy status reported by the administrator device, and the turnout occupancy lock status of turnout area P1 remains unchanged and is still active;

[0086] S703: After receiving a report from the OC device that the GC1 section is occupied, the administrator device assumes that the GC1 section is fault-occupied and therefore determines that there is no train in the P1 section. The administrator device reports the occupancy status of the P1 section as "spot cleared section occupied". However, due to communication delay or data packet loss, the OC device still uses the last reported occupancy status from the administrator device: "spot cleared section cleared". Since the GC1 section is occupied while the administrator device reports the occupancy status as "spot cleared section cleared", the OC device does not update the occupancy locking status based on the administrator device's reported occupancy status. The occupancy locking status of the P1 section remains unchanged and is still active.

[0087] S704: Before the communication interruption, the OC device receives a report from the administrator device that the turnout occupancy status of the turnout area P1 is "turnout clearing section occupied". The OC device updates the turnout occupancy and locking status according to the turnout occupancy status reported by the administrator device. The turnout occupancy and locking status of the turnout area P1 is "inactive".

[0088] During the above process, when a turnout section is occupied due to a fault, the turnout occupancy locking state remains active for a short period from the time the OC device detects that the turnout section is occupied until it receives a report from the administrator that the turnout occupancy status has changed to "turnout cleared section occupied." During this time, the turnout cannot be moved. After the OC device receives a report from the administrator that the turnout occupancy status has changed to "turnout cleared section occupied," the turnout occupancy locking state becomes inactive, and the turnout can be moved. The time from the time the OC device detects that the turnout section is occupied until it receives a report from the administrator that the turnout occupancy status has changed to "turnout cleared section occupied" depends on the timing of the communication interruption and the communication quality.

[0089] Reference Appendix Figure 8 As shown, some embodiments of the present invention further provide a turnout occupancy locking determination system, including:

[0090] Section Status Acquisition Module 1: The OC device detects the section status of the turnout section and sends the section status to the administrator device;

[0091] Module 2 for obtaining turnout occupancy status: The administrator device obtains the area status of the turnout area. When the area status is that there is a train in the turnout area, the turnout occupancy status is determined to be that the turnout is occupied. Otherwise, the turnout occupancy status is determined by the area status and the received section status, and the turnout occupancy status is sent to the OC device.

[0092] Module 3 for judging the occupancy and locking status of turnouts: The OC device detects the section status in real time and receives the turnout occupancy status to update the turnout occupancy and locking status. When the section status changes from cleared to occupied, the turnout occupancy and locking status is activated, and the module determines whether to update the turnout occupancy and locking status based on the turnout occupancy status.

[0093] Specifically, the turnout occupancy status acquisition module is as follows:

[0094] First state judgment unit: When the area state is that there is a train in the turnout area, the turnout occupancy state is judged to be that the turnout is occupied.

[0095] Second state judgment unit: When the area state is no train in the turnout area and the section state is cleared, the turnout occupancy state is judged to be turnout cleared and section cleared.

[0096] Third state judgment unit: When the area state is no train in the turnout area and the section state is occupied, the turnout occupancy state is turnout cleared section occupied.

[0097] The turnout occupancy and locking status determination module further includes:

[0098] Section status judgment unit: When the section status changes from cleared to occupied, the turnout occupancy lock status is activated, and the turnout occupancy lock status is determined based on the turnout occupancy status, and then the turnout occupancy status judgment unit is entered.

[0099] Otherwise, the turnout occupancy and locking status is not updated, and the turnout occupancy and locking status is determined based on the turnout occupancy status, and then the turnout occupancy status determination unit is entered.

[0100] The turnout occupancy status determination unit further includes:

[0101] When the turnout occupancy status is "turnout occupied", then update the turnout occupancy lockout status to "active".

[0102] When the turnout occupancy status is "turnout cleared section occupied", then update the turnout occupancy locking status to "inactive".

[0103] When the turnout occupancy status is "turnout cleared section cleared" and the section status is "cleared", then the turnout occupancy and locking status is updated to "inactive".

[0104] When the turnout occupancy status is "turnout cleared section cleared" and the section status is "occupied", the turnout occupancy and locking status will not be updated.

[0105] After the section status changes to occupied, if the administrator device does not receive the section status sent by the OC device and determines that the turnout occupancy status is cleared and the section is cleared, then...

[0106] Alternatively, if the OC device does not receive the turnout occupancy status from the administrator device and assumes that the turnout occupancy status is cleared, the OC device will not update the turnout occupancy and locking status based on the turnout occupancy status.

[0107] It should be noted that the above is a reference method and system for judging turnout occupancy and locking, and the present invention is not limited thereto.

[0108] The embodiments of the present invention ensure that when a train with no available position unexpectedly enters a turnout section, the turnout occupancy locking state remains active from the moment the OC device detects that the turnout section is occupied. This prevents the turnout from being able to move after a train with no available position unexpectedly enters the turnout area, thus solving the technical problem of the safety risk that the turnout can move after a train with no available position unexpectedly enters the turnout area in the existing train autonomous operation system using distributed resource processing methods.

[0109] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0110] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
