Description

Technical Field

[0001] This invention relates to the field of railway route unlocking technology, and more specifically to a route unlocking method under fault scenarios. Background Technology

[0002] In the field of railway technology, unlocking a route refers to releasing the requisition status of corresponding turnout equipment, signal equipment, and section equipment on a route. After a route is locked, corresponding train operations can be carried out. When the operations are completed or the intention is changed to no longer use the equipment, it is necessary to unlock the equipment on the route to ensure that other operations on the equipment passing through the route are not affected, thereby improving operational efficiency.

[0003] There are four methods for unlocking routes: cancellation unlocking, manual unlocking, segmented unlocking, and section fault unlocking. Cancellation unlocking means immediate unlocking without delay when the train has not yet passed through and the approach to locking has not yet occurred. Manual unlocking means delayed unlocking when the train has not yet passed through and the approach to locking has already occurred. Segmented unlocking means segmented unlocking after the train has passed through the route normally, based on a three-point check.

[0004] The above three methods all refer to route unlocking under the condition that the route is complete and fault-free. When a fault exists on the route, specific personnel can perform operations on each of the unlocked sections of the route one by one under specific conditions; this is called section fault unlocking. If the first section within the route is faulty, no unlocking method can be performed on the entire route, affecting operational efficiency. If multiple unlocked sections remain, performing section fault unlocking operations on each one is also time-consuming and labor-intensive. If the locking state of equipment that is currently in use on the route is mistakenly unlocked, it may cause the train to derail, affecting traffic safety. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, this invention discloses a route unlocking method under fault scenarios. This invention proposes a route unlocking method under fault scenarios that conforms to British standards, while taking into account both safety and efficiency as much as possible. This method aims to provide a fault unlocking method when the equipment in the route fails and the route lockout cannot be unlocked by canceling unlocking, manual unlocking, or segmented unlocking.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A method for unlocking a route in a fault scenario includes the following steps:

[0008] I. Fault Unlocking Processing Stage

[0009] S1. Obtain the fault unlocking operation and determine whether the fault unlocking operation conditions are met. If they are met, the fault unlocking processing conditions are established.

[0010] Preferably, step S1 includes:

[0011] Condition 1: Obtain the fault unlock command;

[0012] Condition 2: The segment being operated on has a path to the segment outside it that is in a locked state.

[0013] Condition 3: The route where the section being operated is located is not in a delayed unlocking period, including not in a manual unlocking delay period or a fault unlocking delay period;

[0014] When conditions one, two, and three are met simultaneously, it indicates that a fault unlocking operation has been performed on the locked route, and the fault unlocking operation conditions are met, that is, the fault unlocking processing conditions are met.

[0015] Preferably, in step S1, when it is confirmed that there is no vehicle, the terminal outside the fault route obtains the fault route unlocking operation command, and determines whether the fault unlocking conditions are met based on the terminal outside the route. If the fault unlocking conditions are met and the terminal is not in the delayed unlocking period, the fault unlocking operation conditions are established, and the fault unlocking processing conditions are output.

[0016] In this invention, the fault unlocking process stage refers to the manual operation of the terminal outside the faulty route by the station duty officer when the station duty officer confirms that there is no train. After the software checks that the fault unlocking operation conditions are met, it outputs that the fault unlocking process conditions are met.

[0017] Preferably, in step S1, the outer segment of the terminal refers to the segment between the route terminal and the blocking signal. When the directions of the terminal and the blocking signal of the route are the same, it is the inner segment of the blocking signal.

[0018] Preferably, in step S1, the blocking signal refers to a signal with the same direction and nature as the starting signal.

[0019] Preferably, in step S1, the fault unlocking condition refers to the route where the external section of the route terminal is located being locked.

[0020] II. Fault Unlocking Route Judgment Stage

[0021] S2. After the conditions for fault unlocking are met, identify the fault-unlockable routes among the existing routes, and output the timing information for starting the fault unlocking route after identification.

[0022] Preferably, in step S2, identifying unlockable faulty routes in the current routes involves identifying the properties of unlockable faulty routes in the current routes, where the unlockable route properties include train routes, guiding routes, and shunting routes.

[0023] In this invention, the fault unlocking route determination stage refers to extracting the nature of currently unlockable routes. Route nature refers to train routes, guiding routes, and shunting routes.

[0024] In step S2, once the fault unlocking condition is met, the software identifies the existing path, judges the unlockable path, and provides the unlockable path judgment result.

[0025] Preferably, step S2 includes the following steps:

[0026] S21. Determine whether the fault unlocking section is locked by the train route. If not, proceed to step S22. If yes, determine whether the currently unlockable route is a train route. If it is a train route, proceed to step S24.

[0027] Preferably, in step S21, the criteria for determining whether the currently unlockable route is a train route include:

[0028] Condition 4: The current fault-unlocked section's route locking range only contains train routes;

[0029] Condition 5: There are protective routes and guiding routes for train routes within the current fault unlocking section's route locking range;

[0030] Condition 6: The current fault unlocking section has a protected route and a shunting route within its route locking range;

[0031] When any one of conditions four, five, or six is ​​met, it indicates that the currently unlockable route is the train route.

[0032] Preferably, in step S21, the existence of a protective route and a guiding route for a train route refers to the following: when a train route has a protective route that has not been unlocked, a guiding route without a protective route can be followed.

[0033] The aforementioned protected routes and shunting routes refer to the fact that when a train route has a protected route that has not been unlocked, a shunting route can be arranged accordingly.

[0034] S22. Determine whether the fault unlocking section is locked by the guided route. If not, proceed to step S23. If yes, determine whether the currently unlockable route is a guided route. If it is a guided route, proceed to step S24.

[0035] Preferably, in step S22, the criteria for determining whether the currently unlockable path is a guided path include:

[0036] Condition 7: The current fault unlocking section's route locking range only contains a guide route;

[0037] Condition 8: The current fault unlocking section has a protected route and a shunting route within its route locking range;

[0038] When either condition seven or condition eight is met, it indicates that the currently unlockable path is the guiding path.

[0039] Preferably, in step S22, the existence of a protective route and a shunting route with a guiding route means that when a protective route is left behind by the guiding route and has not been unlocked, a shunting route can be followed.

[0040] S23. Determine whether the fault unlocking section is locked by the shunting route. If so, determine whether the currently unlockable route is a shunting route. If it is a shunting route, proceed to step S24.

[0041] Preferably, in step S23, the criteria for determining whether the currently unlockable route is a shunting route include:

[0042] Condition 9: The current fault unlocking section's route locking range only contains shunting routes;

[0043] When condition nine is met, it means that the currently unlockable route is the shunting route.

[0044] In this invention, the determination of train routes, guiding routes, and shunting routes is performed sequentially. That is, first, it is determined whether it is a train route; if the train route does not meet the requirements, it is then determined whether it is a guiding route; if the guiding route does not meet the requirements, it is then determined whether it is a shunting route. This hierarchical determination is based on the following reasons: In British interlocking, firstly, a train route with a protected route can be traced back to a guiding route or shunting route without a protected route, and a guiding route with a protected route can be traced back to a shunting route without a protected route; secondly, all train routes have a protected route, while guiding routes may not have a protected route, and shunting routes definitely will not have a protected route. For fault unlocking of normal routes, the unlocking level is not required, but considering the type and number of routes within the station, and the possibility of ununlocked sections of protected routes, it is considered that prioritizing train routes is preferable, followed by guiding routes, and lastly, shunting routes.

[0045] S24. After obtaining the current unlockable route properties, output the timing information for starting and unlocking faulty routes.

[0046] III. Fault Path Unlocking Timing Phase

[0047] S3. Start the fault unlock countdown. During the countdown, continuously check the fault unlock countdown judgment conditions. If the conditions are not met, stop the countdown. After the countdown ends, give the judgment result of whether the current route can be unlocked.

[0048] Preferably, in step S3, the fault unlocking timing judgment condition includes the fault unlocking timing time being reached and the fault unlocking condition being met, that is, there is a path with it as the external segment of the terminal in a locked state.

[0049] In this invention, during the countdown period, it is necessary to continuously check the fault unlocking conditions. The purpose is that if the fault unlocking conditions are not met during the countdown, it means that there is no path outside the terminal segment that is still locked, and there is no need to continue the countdown.

[0050] Preferably, step S3 includes:

[0051] Condition 10: The fault unlocking conditions are met, and the delay time for the currently unlockable fault route has expired;

[0052] Condition 11: If the fault unlocking condition is not met, the timer is interrupted and the process ends;

[0053] When condition ten is met, it means that the current faulty path can be unlocked, output the information that the current path can be unlocked and proceed to step S4; when condition eleven is met, it means that there is no unlockable faulty path and the process ends.

[0054] IV. Fault Unlocking and Troubleshooting Phase

[0055] S4. If the result of the judgment on whether the current path can be unlocked is that it can be unlocked, unlock the locked section in the unlockable faulty path in the currently existing path.

[0056] The unlocking fault path stage of the present invention refers to the unlocking of all locked sections in the fault path determined in step S3 after obtaining the unlockable information of the current fault path in step S3.

[0057] Preferably, in step S4, the unlocked sections within the fault path are unlocked one by one, and the fault path unlocking ends after each section is unlocked.

[0058] In this invention, it is determined whether each segment in the faulty route is unlocked, and the unlocked segments in the faulty route are unlocked one by one. Once each segment is unlocked, the faulty route is considered to be unlocked.

[0059] The above steps include the following judgment conditions:

[0060] Condition 12: The section is in a locked state, and the route where the section is located is the unlockable fault route determined in step S3.

[0061] When condition 12 is met, it indicates that the unlocking condition for the currently locked section is met, and the locking state can be released. Condition 12 is executed for all sections within the faulty route to release the requisition status of the faulty route.

[0062] The beneficial effects of this invention are:

[0063] The route unlocking method provided by this invention, in accordance with British Standards and combined with existing section fault unlocking methods, proposes a new fault unlocking method. When there are sections in the route that cannot be unlocked for some reason, all remaining unlocked sections can be unlocked in one operation, thus improving efficiency.

[0064] The fault path unlocking method provided by this invention determines the path type of the fault path to be unlocked, preventing the original locked path and the follow-up path from being unlocked normally when the remaining section of the protected path is not unlocked, thus improving efficiency.

[0065] The route unlocking method for fault scenarios provided by this invention provides an unlocking delay during fault unlocking, preventing the erroneous unlocking and requisition of the middle section, and greatly balancing safety and efficiency. Attached Figure Description

[0066] Figure 1 This is a schematic diagram of the four stages of the present invention;

[0067] Figure 2 The following is a flowchart illustrating the logic of unlocking fault paths in this invention.

[0068] Figure 3 This is a schematic diagram of the route scenario for the present invention. Detailed Implementation

[0069] The following will provide a clear and complete description of the concept, specific structure, and technical effects of the present invention in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention.

[0070] Example 1

[0071] A method for unlocking a path in a fault scenario, such as Figure 1 and 2 As shown, it includes the following steps:

[0072] S1. Obtain the fault unlocking operation and determine whether the fault unlocking operation conditions are met. If they are met, the fault unlocking processing conditions are established.

[0073] S2. After the conditions for fault unlocking are met, identify the fault-unlockable routes among the existing routes, and output the timing information for starting the fault unlocking route after identification.

[0074] S3. Start the fault unlock countdown. During the countdown, continuously check the fault unlock countdown judgment conditions. If the conditions are not met, stop the countdown. After the countdown ends, give the judgment result of whether the current route can be unlocked.

[0075] S4. If the result of the judgment on whether the current path can be unlocked is that it can be unlocked, unlock the locked section in the unlockable faulty path in the currently existing path.

[0076] Example 2

[0077] This embodiment further elaborates on step S1 based on embodiment 1.

[0078] like Figure 2 As shown, step S1 includes:

[0079] Condition 1: Obtain the fault unlock command;

[0080] Condition 2: The segment being operated on has a path to the segment outside it that is in a locked state.

[0081] Condition 3: The route where the section being operated is located is not in a delayed unlocking period, including not in a manual unlocking delay period or a fault unlocking delay period;

[0082] When conditions one, two, and three are met simultaneously, it indicates that a fault unlocking operation has been performed on the locked route, and the fault unlocking operation conditions are met, that is, the fault unlocking processing conditions are met.

[0083] In step S1, when it is confirmed that there is no vehicle, the terminal outside the fault route obtains the fault route unlocking operation command, and determines whether the fault unlocking conditions are met based on the terminal outside the route. If the fault unlocking conditions are met and the delay unlocking period is not in effect, the fault unlocking operation conditions are established, and the fault unlocking processing conditions are output.

[0084] In this invention, the fault unlocking process stage refers to the manual operation of the terminal outside the faulty route by the station duty officer when the station duty officer confirms that there is no train. After the software checks that the fault unlocking operation conditions are met, it outputs that the fault unlocking process conditions are met.

[0085] In step S1, the outer segment of the terminal refers to the segment between the route terminal and the blocking signal. When the directions of the terminal and the blocking signal of the route are the same, it is the inner segment of the blocking signal.

[0086] In step S1, the blocking signal refers to a signal with the same direction and nature as the starting signal.

[0087] In step S1, the fault unlocking condition refers to the route where the external section of the route terminal is located being locked.

[0088] Example 3

[0089] This embodiment further elaborates on step S2 based on embodiment 2.

[0090] In step S2, identifying unlockable faulty routes in the current routes means identifying the nature of unlockable faulty routes in the current routes. The nature of unlockable routes includes train routes, guiding routes, and shunting routes.

[0091] In this invention, the fault unlocking route determination stage refers to extracting the nature of currently unlockable routes. Route nature refers to train routes, guiding routes, and shunting routes.

[0092] In step S2, once the fault unlocking condition is met, the software identifies the existing path, judges the unlockable path, and provides the unlockable path judgment result.

[0093] like Figure 2 As shown, step S2 includes the following steps:

[0094] S21. Determine whether the fault unlocking section is locked by the train route. If not, proceed to step S22. If yes, determine whether the currently unlockable route is a train route. If it is a train route, proceed to step S24.

[0095] In step S21, the criteria for determining whether the currently unlockable route is a train route include:

[0096] Condition 4: The current fault-unlocked section's route locking range only contains train routes;

[0097] Condition 5: There are protective routes and guiding routes for train routes within the current fault unlocking section's route locking range;

[0098] Condition 6: The current fault unlocking section has a protected route and a shunting route within its route locking range;

[0099] When any one of conditions four, five, or six is ​​met, it indicates that the currently unlockable route is the train route.

[0100] In step S21, the existence of a protected route and a guiding route for a train route refers to the following: when a train route has a protected route that has not been unlocked, a guiding route without a protected route can be followed up.

[0101] The aforementioned protected routes and shunting routes refer to the fact that when a train route has a protected route that has not been unlocked, a shunting route can be arranged accordingly.

[0102] S22. Determine whether the fault unlocking section is locked by the guided route. If not, proceed to step S23. If yes, determine whether the currently unlockable route is a guided route. If it is a guided route, proceed to step S24.

[0103] In step S22, the conditions for determining whether the currently unlockable path is a guided path include:

[0104] Condition 7: The current fault unlocking section's route locking range only contains a guide route;

[0105] Condition 8: The current fault unlocking section has a protected route and a shunting route within its route locking range;

[0106] When either condition seven or condition eight is met, it indicates that the currently unlockable path is the guiding path.

[0107] In step S22, the existence of a protective route and a shunting route with a guiding route means that when a protective route is left behind by the guiding route and has not been unlocked, a shunting route can be followed.

[0108] S23. Determine whether the fault unlocking section is locked by the shunting route. If so, determine whether the currently unlockable route is a shunting route. If it is a shunting route, proceed to step S24.

[0109] In step S23, the criteria for determining whether the currently unlockable route is a shunting route include:

[0110] Condition 9: The current fault unlocking section's route locking range only contains shunting routes;

[0111] When condition nine is met, it means that the currently unlockable route is the shunting route.

[0112] S24. After obtaining the current unlockable route properties, output the timing information for starting and unlocking faulty routes.

[0113] Example 4

[0114] This embodiment further elaborates on step S3 based on embodiment 3.

[0115] In step S3, the fault unlocking timing judgment condition includes the fault unlocking timing time being reached and the fault unlocking condition being met, that is, there is a path with it as the external segment of the terminal in a locked state.

[0116] In this invention, during the countdown period, it is necessary to continuously check the fault unlocking conditions. The purpose is that if the fault unlocking conditions are not met during the countdown, it means that there is no path outside the terminal segment that is still locked, and there is no need to continue the countdown.

[0117] Step S3 includes:

[0118] Condition 10: The fault unlocking conditions are met, and the delay time for the currently unlockable fault route has expired;

[0119] Condition 11: If the fault unlocking condition is not met, the timer is interrupted and the process ends;

[0120] When condition ten is met, it means that the current faulty path can be unlocked, output the information that the current path can be unlocked and proceed to step S4; when condition eleven is met, it means that there is no unlockable faulty path and the process ends.

[0121] Example 5

[0122] This embodiment further elaborates on step S4 based on embodiment 4.

[0123] The unlocking fault path stage of the present invention refers to the unlocking of all locked sections in the fault path determined in step S3 after obtaining the unlockable information of the current fault path in step S3.

[0124] In step S4, the unlocked sections within the faulty path are unlocked one by one. Once all sections have been unlocked, the faulty path unlocking process is complete.

[0125] In this invention, it is determined whether each segment in the faulty route is unlocked, and the unlocked segments in the faulty route are unlocked one by one. Once each segment is unlocked, the faulty route is considered to be unlocked.

[0126] The above steps include the following judgment conditions:

[0127] Condition 12: The section is in a locked state, and the route where the section is located is the unlockable fault route determined in step S3.

[0128] When condition 12 is met, it indicates that the unlocking condition for the currently locked section is met, and the locking state can be released. Condition 12 is executed for all sections within the faulty route to release the requisition status of the faulty route.

[0129] Example 5

[0130] refer to Figure 3 This describes the technical solution of the present invention.

[0131] refer to Figure 3 Assume that in the down direction there are train routes with protection routes 43-42, main routes 1-12, guiding routes 1-12, and shunting routes 1-12, with all routes having a 1G terminus outside their terminal sections; and in the up direction there are guiding routes with protection route W21ADG, main routes 42-43, and shunting routes 42-43, with all routes having a 1G terminus outside their terminal sections. Based on this, refer to... Figure 3 Taking the current train route 1-12 as an example, if a section within the protected route of this train route is not unlocked due to a fault, and a shunting route 1-12 is added, the analysis will proceed from four stages: the fault unlocking process, the fault unlocking route judgment stage, the fault unlocking timing stage, and the fault unlocking route stage. Figure 2 This invention introduces a route unlocking method under fault scenarios.

[0132] First, during the fault unlocking process, the conditions for fault unlocking are analyzed:

[0133] S1, the software detects that a 1G fault unlocking operation has been performed. First, it obtains the fault unlocking command, extracts the 1-12 train, 1-12 guide train, 1-12 shunting train, 42-43 guide train, and 42-43 shunting train on the route where 1G is located, and identifies that there are sections that have not been unlocked. Then, it determines that the countdown timers 12 and 43 on the left and right sides of 1G have not started, and no fault unlocking operation for 1G has been performed, that is, the fault unlocking delay timer has not started. At this point, the conditions for handling the fault unlocking are met.

[0134] Secondly, the fault unlocking path determination stage is introduced, and the specific steps are as follows:

[0135] S2. After the fault unlocking conditions are met, the software detects that the protection routes 43-42 of the down train route 1-12 where 1G is located and the down shunting route 1-12 are still locked. According to step S21, the routes that can be unlocked at present are train route 1-12 and its protection routes 43-42. At this time, the main route 1-12 has been unlocked, so the route that can be unlocked is 43-42.

[0136] Next, the fault path unlocking timing phase will be introduced, with the specific steps as follows:

[0137] S3: After identifying the unlockable route, the software starts a fault unlock countdown. During the countdown, the fault unlock conditions are continuously checked. If the conditions are not met, the countdown stops. After the fault unlock countdown ends, the unlock conditions for protected routes 43-42 are recorded as met.

[0138] Finally, the fault unlocking process is described:

[0139] S4. After the unlocking conditions of protected route 43-42 are met, the locking status of sections such as W23B is released. After all the locked sections in the route are unlocked, protected route 43-42 is released from requisition status, and the locking nature of train route 1-12 is released.

[0140] The process ends at this point.

[0141] The embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalents or substitutions are all included within the scope defined by the claims of the present invention.
