Description

Technical Field

[0001] This invention relates to the field of rail transit control technology, and in particular to a method and device for controlling shunting turnaround routes based on fully electronic interlocking. Background Technology

[0002] In urban rail transit, shunting routes are mainly used for shunting operations in the depot. Unlocking during a shunting return is formed during shunting track switching operations within the depot. Shunting track switching operations generally require two processes: first, the shunting route is pulled out (hereinafter referred to as "pulling out route"); second, the shunting route is turned back (hereinafter referred to as "turning back route"). For handling unlocking during a shunting return, the computer interlocking system follows the principles of the 6502 electrical centralized interlocking system.

[0003] The existing shunting turnaround operation method, due to its segmented unlocking approach, means that if a train fails to stop promptly after passing a turnaround signal, the turnaround route is initiated from that signal. If there are switches between the train and the turnaround signal, and the train performs the turnaround operation based on the open turnaround signal, the switches between the train and the turnaround signal are not locked by any other route. This creates the so-called "isolated unlocking of switches for signal viewing" problem, posing a safety risk of train derailment. Furthermore, the existing shunting route handling method (using segmented unlocking) results in trains only being able to move forward on the route, unable to reverse, thus failing to meet the requirement for free movement during shunting operations.

[0004] Currently, no effective solution has been proposed to address the safety risks associated with using the 6502 circuit segmented unlocking method for shunting turnaround operations. Summary of the Invention

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a method, device, computer equipment, and computer-readable storage medium for controlling shunting turnaround routes based on fully electronic interlocking. This replaces the 6502 circuit method used in related technologies for shunting turnaround operations by using pure software logic instead of the circuit, thereby reducing equipment costs and space requirements.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, embodiments of this application provide a shunting mid-route turnaround route control method based on fully electronic interlocking, including:

[0008] Inspect the shunting route where operations are underway;

[0009] Detect whether a turnaround signal associated with the shunting route exists;

[0010] If a turnaround signal associated with the shunting route is detected, determine whether the turnaround signal is in an open state;

[0011] If the turnaround signal is in the open state, then determine whether the route with the turnaround signal as the starting signal is the turnaround route of the shunting route;

[0012] If it is determined that the route with the turnaround signal as the starting signal is the turnaround route of the shunting route, then the shunting route and the turnaround route are associated, wherein the turnaround route is the route with the turnaround signal as the starting signal;

[0013] Detect whether the first section inside the turnaround route is occupied and whether the adjacent section of the turnaround route is cleared;

[0014] If the first section inside the turnaround route is detected to be occupied and the adjacent section of the turnaround route has been cleared, then the section that could not be unlocked due to the midway turnaround will be unlocked.

[0015] In some embodiments, associating the shunting route with the turnaround route includes:

[0016] The type of the turnaround signal is determined, wherein the type includes: differential signal, parallel signal, and signal located inside the shunting route;

[0017] The shunting route is associated with the turnaround route based on the type of the turnaround signal.

[0018] In some embodiments, determining the type of the turnaround signal includes:

[0019] Obtain the protection direction of the shunting route;

[0020] When the protection direction of the shunting route is to the right, if the right section of the turning signal coincides with the approach section of the shunting route, then the turning signal is determined to be the differential signal; if the left section of the turning signal coincides with the approach section of the shunting route, then the turning signal is determined to be the parallel signal; if there is a valid section in the shunting route that coincides with the approach section of the turning signal, then the turning signal is determined to be the signal located inside the shunting route.

[0021] When the protection direction of the shunting route is to the left, if the left section of the turning signal coincides with the approach section of the shunting route, the turning signal is determined to be the differential signal; if the right section of the turning signal coincides with the approach section of the shunting route, the turning signal is determined to be the parallel signal; if there is a valid section in the shunting route that coincides with the approach section of the turning signal, the turning signal is determined to be the signal located inside the shunting route.

[0022] In some embodiments, associating the shunting route with the turnaround route based on the type of the turnaround signal includes:

[0023] If the turnaround signal is the signal located inside the shunting route, and if the approach section of the turnaround route is occupied, the first section inside the turnaround signal is occupied and has been released from the shunting route, then the shunting route is associated with the turnaround route.

[0024] When the turnaround signal is either the parallel signal or the differential signal, if the approach section of the turnaround route is occupied, the first section inside the turnaround signal is occupied and has been released from the shunting route, it is determined whether the signal cross-voltage status is normal; if it is determined that the signal cross-voltage status is normal, the shunting route is associated with the turnaround route.

[0025] In some embodiments, determining whether the trans-voltage state of the signal is normal includes:

[0026] Detect whether there is a signal on the first section inside the shunting route and whether it has been released from the shunting route;

[0027] If there is a signal on the first section inside the shunting route and it has not been released from the shunting route, then it is determined whether the existing signal is in an open state.

[0028] If the existing signal is in an open state, and both the first section inside the shunting route and the adjacent section of the shunting route are occupied, then the signal cross-pressure status is determined to be normal.

[0029] In some embodiments, unlocking sections that cannot be unlocked due to mid-journey reversal includes:

[0030] Determine the associated routes of the shunting route;

[0031] Unlock the shunting route and the associated route.

[0032] In some embodiments, determining the associated route of the shunting route includes:

[0033] Determine whether the departure section of the shunting route coincides with the first section inside the signal of the searched route, and whether the departure section is not unlocked;

[0034] If it is determined that the departure section of the shunting route coincides with the first section inside the signal of the search route, and the departure section is not unlocked, then it is determined whether the approach section of the search route is occupied and has not been released from the shunting route.

[0035] If it is determined that the approach section of the search route is occupied and has not been released from the shunting route, then it is determined whether the signal cross-voltage status is normal.

[0036] If the signal cross-voltage status is determined to be normal, then the search route is set as the associated route of the shunting route.

[0037] In some embodiments, after setting the retrieval route as an associated route of the shunting route, the method further includes:

[0038] Traverse all segments of the associated path and determine whether there are any segments that have been released or occupied;

[0039] If it is determined that there is a released or occupied segment, then the associated path is canceled.

[0040] In some embodiments, the unlocking process for the shunting route and the associated route includes:

[0041] When the turnaround signal is located inside the shunting route, if the section of the shunting route that overlaps with the section of the turnaround route is free, and the section of the shunting route that overlaps with the first section inside the turnaround route is occupied and released from the shunting route, then it is determined that the vehicle has completely entered the inside of the turnaround signal, and the section behind the turnaround signal is unlocked in one go; if there is no released and occupied section behind the turnaround signal, then it is determined that the unlocking conditions are met, and the section behind the turnaround signal is unlocked in one go.

[0042] When the turnaround signal is either the parallel signal or the differential signal, if the section of the shunting route that overlaps with the section of the turnaround route is free, and the section of the shunting route that overlaps with the first section inside the turnaround route is occupied and released from the shunting route, then it is determined that the vehicle has completely entered the inside of the turnaround signal, and the section behind the turnaround signal is unlocked in one go; it is then determined whether the signal cross-pressure status is normal; if it is determined that the signal cross-pressure status is normal, then it is determined whether there is a section behind the turnaround signal that has been released and is occupied; if it is determined that there is no section behind the turnaround signal that has been released and is occupied, then it is determined that the unlocking conditions are met, and the section behind the turnaround signal is unlocked in one go.

[0043] Secondly, embodiments of this application provide a shunting mid-route turnaround control device based on fully electronic interlocking, comprising:

[0044] The first detection unit is used to detect shunting routes in progress;

[0045] The second detection unit is used to detect whether there is a turnaround signal associated with the shunting route;

[0046] The first judgment unit is used to determine whether the turnaround signal is in an open state if a turnaround signal associated with the shunting route is detected.

[0047] The second judgment unit is used to determine whether the route with the turnaround signal as the starting signal is the turnaround route of the shunting route if the turnaround signal is in the open state.

[0048] The association unit is used to associate the shunting route with the turnaround route if it is determined that the route with the turnaround signal as the starting signal is the turnaround route of the shunting route, wherein the turnaround route is the route with the turnaround signal as the starting signal;

[0049] The third detection unit is used to detect whether the first section inside the turnaround route is occupied and whether the adjacent section of the turnaround route is cleared.

[0050] The unlocking unit is used to unlock the section that cannot be unlocked due to the midway turnaround if it is detected that the first section inside the turnaround route is occupied and the adjacent section of the turnaround route has been cleared.

[0051] Thirdly, embodiments of this application provide a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor.

[0053] This application adopts the above technical solution. Compared with the prior art, the shunting mid-way turnaround route control method based on fully electronic interlocking provided in this application embodiment detects the shunting route in operation; detects whether there is a turnaround signal associated with the shunting route; if a turnaround signal associated with the shunting route is detected, determines whether the turnaround signal is in an open state; if the turnaround signal is in an open state, determines whether the route with the turnaround signal as the starting signal is the turnaround route of the shunting route; if it is determined that the route with the turnaround signal as the starting signal is the turnaround route of the shunting route... The system associates the shunting route with the turnaround route, where the turnaround route is a route with the turnaround signal as its starting signal. It detects whether the first section within the turnaround route is occupied and whether the adjacent section of the turnaround route is cleared. If the first section within the turnaround route is detected as occupied and the adjacent section of the turnaround route is cleared, the section that cannot be unlocked due to a mid-journey turnaround is unlocked. This application replaces the related technology's use of a 6502 circuit for shunting turnaround operations, solving the safety and efficiency problems caused by the limitations of circuit judgment, and achieving the effect of improving the efficiency and safety of shunting turnaround operations.

[0072] This embodiment provides a method for controlling shunting turnaround routes based on fully electronic interlocking. Figure 1 This is a flowchart of a shunting mid-journey turnaround route control method based on fully electronic interlocking, according to an embodiment of this application. Figure 1 As shown, the process includes the following steps:

[0073] Step S101: Detect the shunting route in progress;

[0074] Step S102: Detect whether there is a turnaround signal associated with the shunting route;

[0075] Step S103: If a turnaround signal associated with the shunting route is detected, determine whether the turnaround signal is in an open state.

[0077] Step S105: If it is determined that the route with the turnaround signal as the starting signal is the turnaround route of the shunting route, then the shunting route and the turnaround route are associated, wherein the turnaround route is the route with the turnaround signal as the starting signal;

[0078] Step S106: Detect whether the first section inside the turnaround route is occupied and whether the adjacent section of the turnaround route is cleared;

[0079] Step S107: If it is detected that the first section inside the turnaround route is occupied and the adjacent section of the turnaround route has been cleared, then the section that cannot be unlocked due to the midway turnaround is unlocked.

[0080] This application embodiment achieves, under fully electronic interlocking, a logic unlocking method using designed software to realize logic judgments that cannot be achieved using the 6502 circuit method through pure software without reducing security. It proposes an improved method for unlocking shunting mid-journey return and an automatic identification method for mid-journey turnaround routes without changing the existing positioning and communication methods. The aim is to optimize the processing of shunting mid-journey return route identification and unlocking, and technically solve the security problems existing in shunting mid-journey return unlocking.

[0081] The automatic identification and processing process of shunting mid-journey turnaround routes based on fully electronic interlocking in this embodiment may include the following steps:

[0082] 1) Configure the shunting turnaround signal for each route through the data file.

[0083] 2) The software enables automatic identification of shunting routes that turn back midway and processes the opening and unlocking of routes.

[0084] 3) Security protection for the entire process of path creation and unlocking through software logic.

[0085] The following is a detailed description of the three processes mentioned above:

[0086] like Figure 2 As shown, for each basic route in the interlocking table, its turnaround signal can be configured in the data. This binds the route to its associated turnaround route.

[0087] In practical applications, when a vehicle is traveling on a route (Route A), and the associated turnaround signal establishes a shunting route (Route B) and the turnaround signal is open, if the vehicle completely enters Route B from Route A, the software logic determines that the vehicle is currently performing a shunting turnaround operation. This method automatically identifies when a vehicle is performing a shunting turnaround operation during logic calculations, allowing the interlocking system to handle the unlocked portion of Route A according to the turnaround operation procedure.

[0088] In some embodiments, associating the shunting route with the turnaround route in step S105 may include:

[0089] Step S1051: Determine the type of the turnaround signal, wherein the type includes: differential signal, parallel signal, and signal located inside the shunting route;

[0090] Step S1052: Associate the shunting route with the turnaround route according to the type of the turnaround signal.

[0091] The specific definition of the relationship between the route and its associated turnaround signal during shunting turnaround operations is as follows:

[0092] 1. The reverse signals included within the basic route range can be used as intermediate turnaround signals for the route;

[0093] 2. The parallel reverse signal at the beginning of this basic route can be used as a turnaround signal in the middle of the route;

[0094] 3. When the approach section of the basic route is a branchless section, the reverse signal on the section can be used as a turnaround signal for the route.

[0095] Combination Figures 3 to 5 The types of turnaround signals are explained below:

[0096] Figure 3 The diagram shows the signals located inside the shunting route, including the reverse signals within the route area. In routes D121 to D127 (Route A), there are two turnaround signals, D139 and D141. When the train has completely entered Route A and occupied 121DG, the route (Route B) is arranged with signal D141 as the starting point. When the train has completely entered 117DG, a shunting turnaround operation is completed.

[0097] Figure 4The diagram shows a parallel signal system. A parallel signal exists at the beginning of a route, with the beginning signal and the turnaround signal on the same insulating joint. Directly below the beginning signal of route D107 to D113 (Route A), there is a parallel signal D105. When a vehicle fully enters Route A and occupies 103DG, a route (Route B) is formed with D105 as the beginning signal. When the vehicle fully enters 101DG, a shunting turnaround operation is completed.

[0098] Figure 5 The diagram shows a differential signal. When the approach section is a non-spindle section, the reverse signal on the section can be used as a turnaround signal for the route. After the route from D348 to D344 (Route A) is arranged, its approach section 328 / 356G is a non-spindle section, and there is a reverse signal D354 on this section. When the vehicle enters Route A and maintains occupancy of 328 / 356G, the route (Route B) with D354 as the starting signal is arranged. When the vehicle has completely entered 332-356DG, a shunting turnaround operation is constituted.

[0099] In some embodiments, step S1051, determining the type of the turnaround signal, may include:

[0100] Obtain the protection direction of the shunting route;

[0101] When the protection direction of the shunting route is to the right, if the right section of the turning signal coincides with the approach section of the shunting route, then the turning signal is determined to be the differential signal; if the left section of the turning signal coincides with the approach section of the shunting route, then the turning signal is determined to be the parallel signal; if there is a valid section in the shunting route that coincides with the approach section of the turning signal, then the turning signal is determined to be the signal located inside the shunting route.

[0102] When the protection direction of the shunting route is to the left, if the left section of the turning signal coincides with the approach section of the shunting route, the turning signal is determined to be the differential signal; if the right section of the turning signal coincides with the approach section of the shunting route, the turning signal is determined to be the parallel signal; if there is a valid section in the shunting route that coincides with the approach section of the turning signal, the turning signal is determined to be the signal located inside the shunting route.

[0103] In some embodiments, step S1052, which associates the shunting route with the turnaround route based on the type of the turnaround signal, may include:

[0104] If the turnaround signal is the signal located inside the shunting route, and if the approach section of the turnaround route is occupied, the first section inside the turnaround signal is occupied and has been released from the shunting route, then the shunting route is associated with the turnaround route.

[0105] When the turnaround signal is either the parallel signal or the differential signal, if the approach section of the turnaround route is occupied, the first section inside the turnaround signal is occupied and has been released from the shunting route, it is determined whether the signal cross-voltage status is normal; if it is determined that the signal cross-voltage status is normal, the shunting route is associated with the turnaround route.

[0106] This application embodiment designs a dynamic route table, as shown in Tables 1 and 2 below:

[0107] Table 1 Dynamic Route Table

[0108]

[0109]

[0110] Table 2 contains information about each segment in the segment array.

[0111]

[0112] The process for determining the type of turnaround signal and associating shunting routes and turnaround routes in the above embodiments is as follows: Figure 6 The process has already been shown in the document, in addition to the process described above, Figure 6 It also details the process of determining how a route generates a associated shunting turnaround route, enabling accurate judgment. Figures 3 to 5 Has the scenario already been triggered? For example... Figure 6As shown, this embodiment first sets the default value of the function and checks the legality of the shunting route. If it is legal, the initial value of the return value is set; otherwise, the process ends. Then, the dynamic route table is traversed to determine if the route exists. If it exists, the associated turnaround signals are traversed. If an associated turnaround signal exists, the initial value of the approach section of the turnaround route is set, and then it is determined whether the turnaround signal is open. If open, the protection direction and approach section information of the route signal are obtained, and the IDs of the approach section and the inner first section of the turnaround signal are obtained. Then, it is determined whether the turnaround signal is valid. If invalid, a flag is set to not check the turnaround; if the turnaround signal check is valid, subsequent judgments are made based on the protection direction of this route. If the protection direction of this route is to the right: If the right section of the turnaround signal coincides with the adjacent section of the original route, it is determined to be a differential signal; if the left section of the turnaround signal coincides with the adjacent section of the original route, it is determined to be a parallel signal. Traverse the route to find the section that coincides with the adjacent section of the turnaround signal and check if the section is valid. If valid, obtain the index of the section. If such a section exists, the turnaround signal is determined to be inside the route. If the protection direction of this route is to the left: If the left section of the turnaround signal coincides with the adjacent section of the original route, it is determined to be a differential signal; if the right section of the turnaround signal coincides with the adjacent section of the original route, it is determined to be a parallel signal. Traverse the route to find the section that coincides with the adjacent section of the turnaround signal and check if the section is valid. If valid, obtain the index of the section. If such a section exists, the turnaround signal is determined to be inside the route. After determining the type of turnaround signal, the shunting route and turnaround signal are associated for different types. For the case where the turnaround signal is inside the route, condition one is executed: if the approach section of the turnaround route is occupied, the first section inside the turnaround signal has been released from the route, and that section is occupied, then the generated turnaround route is associated. For the case of a parallel signal, condition one is executed: if the approach section of the turnaround route is occupied, the first section inside the turnaround signal has been released from the route, and that section is occupied, then the route signal voltage is checked for normal operation. If the signal voltage is normal, then the generated turnaround route is associated. The case of a differential signal is the same as for a parallel signal, and will not be elaborated here. Finally, the processing and reverse direction checks can be performed, and the index of the returning approach section can be obtained.

[0113] In some embodiments, determining whether the signal transducer voltage state is normal may include:

[0114] Detect whether there is a signal on the first section inside the shunting route and whether it has been released from the shunting route;

[0115] If there is a signal on the first section inside the shunting route and it has not been released from the shunting route, then it is determined whether the existing signal is in an open state.

[0116] If the existing signal is in an open state, and both the first section inside the shunting route and the adjacent section of the shunting route are occupied, then the signal cross-pressure status is determined to be normal.

[0117] In this embodiment of the application, the process for determining whether the signal trans-voltage state is normal can be as follows: Figure 7 As shown, this logic can determine which sections are designated as non-unlockable sections during shunting turnaround operations. If the cross-pressure is normal, the associated section is extended to the associated route; if the cross-pressure is abnormal, the associated route remains unlocked. For example... Figure 7 As shown, in this embodiment, the route type is first obtained. If it is a shunting or train route, the first section within that route is obtained. If there is a signal on that section, and that section is not released from the route, it is determined whether the signal is open. If the signal is open, and both the section and the adjacent section of the route are occupied, it is determined that the train is in a cross-voltage signal state. If the signal is closed, it is determined again whether the route is a shunting route. If the current route is a shunting route, and the vehicle is in a normal cross-voltage state, the association remains unchanged; if the cross-voltage is abnormal, the association is canceled. Then, it is determined whether the section has a fault. If a fault occurs, it is determined that the train is not in a cross-voltage signal state.

[0118] This application embodiment, by associating the route and its turnaround signal in the data and combining the judgment of software logic, can automatically identify and process the shunting turnaround operation.

[0119] First, let's explain the route processing:

[0120] 1. When a train enters a shunting route and a section of the route cannot be unlocked due to a midway turnaround, the section should be automatically unlocked after the train has entered the inside of the open turnaround signal and cleared all the locked sections.

[0121] 2. When a train enters a shunting route and all sections of the route cannot be unlocked due to midway turnaround operations, the train will be automatically unlocked after checking the train's sequential exit from the route and its adjacent sections.

[0122] 3. When a train enters the inner side of a parallel signal, and due to a mid-route turnaround operation, all sections of the route cannot be unlocked, the route will automatically unlock after it is confirmed that the train has entered the inner side of the signal according to the open reverse parallel signal and has cleared all the locked sections.

[0123] For fully electronic interlocking, the challenge in designing shunting turnaround operations is the timing of unlocking the turnaround route. Correctly judging the timing can prevent the route from not unlocking or being unlocked incorrectly, thus avoiding dangerous accidents such as derailment.

[0124] Under normal circumstances, the 6502 mid-journey return unlocking circuit in the relevant technology will automatically unlock after meeting three conditions.

[0125] Condition 1: The original signal for the outgoing route has been turned off.

[0126] Condition 2: The original access route was previously occupied and has been cleared.

[0127] Condition 3: The shunting train did indeed turn back.

[0128] For fully electronic interlocking, the circuit logic is implemented by the upper-level interlocking software logic, and the implementation logic is as follows:

[0129] Condition 1: This condition can be obtained by checking the status of the signal controller execution unit.

[0130] Condition 2: If a shunting route has previously been occupied, it must first be determined whether the occupation was normal. This check method involves verifying the conditions for normal occupation when the shunting route is cleared: vehicles sequentially entered the route when the signal was open. Sequential occupation can be determined by the occupation of the approach section of the route, followed by the occupation of the first section inside the route. Since the signal remains open when the approach section of a shunting route is not cleared and the first section inside the route is occupied, this condition can be used to record the signal status at that moment. This status, along with the sequential occupation determination, can then be used to determine if Condition 2 is met.

[0131] Condition 3: From Figures 3 to 5 As described above, when the software identifies the turnaround route and determines that vehicles sequentially enter and exit the approach section of the turnaround route, it can be clearly determined that the vehicles have completed the turnaround.

[0132] The above method can implement the circuit logic of 6502. However, for fully electronic interlocking, whether a shunting operation within a combined route is a primary or secondary operation still needs to be determined through software logic. Because of relay associations, 6502 can determine the connections between routes. For fully electronic interlocking, the determination needs to check whether a vehicle has crossed an adjacent route when the route is occupied. By using condition 2 and the recorded signal status, it is possible to automatically and accurately determine whether the adjacent routes involve the same vehicle or two different vehicles.

[0133] The fully electronic interlocking system describes the timing for unlocking during shunting turnaround operations as follows: Unlocking is triggered when it is determined that the shunting train has indeed turned back and has fully entered the turnaround signal. This timing is determined by the train's sequence occupying the turnaround signal and the clearance of the approach section of the turnaround route. When it is determined that the train has successfully and fully entered the turnaround route, the sections of the route that failed to unlock properly due to the turnaround operation are unlocked in one go.

[0134] The unlocking method for the middle section of the route that failed to unlock normally due to mid-way turnaround operations is as follows:

[0135] First, determine whether the section failed to unlock properly due to a mid-way turnaround operation. Then, unlock these sections as follows:

[0136] (1) For Figure 3 and Figure 4 In this scenario, route A is associated with route B. When the vehicle fully enters route B, the approach section of route B is periodically checked for clearance. When the approach section is cleared, it is found that route A is not unlocked, and the approach section is contained in route A. Furthermore, route A and route B have a turnaround relationship. At this time, according to the requirements of the iron standard, the unlocked section of route A is unlocked.

[0137] (2) For Figure 5 In this scenario, route A is associated with route B. When the vehicle fully enters route B, the approach section of route B is periodically checked for clearance. When the approach section is cleared, it is found that route A is not unlocked, and the approach section is also the approach section of route A. Furthermore, route A and route B have a turnaround relationship. At this time, according to the requirements of the iron standard, the unlocked section of route A is unlocked.

[0138] (3) For Figure 5 In a scenario where vehicles are turning back to each other, the judgment method is to determine if route A is completely cleared and the vehicle has completely entered route B. In this case, the section in route A is considered to be the section that failed to be unlocked due to the midway turning back operation.

[0139] The unlocking method for the external combination route of the turnaround route is as follows:

[0140] If a turnaround operation involves multiple basic routes, starting from the basic route closest to the open turnaround signal, when the train has fully entered the turnaround signal, if the basic route that cannot be unlocked due to the turnaround operation meets the unlocking conditions, then all sections of that route will be unlocked at once. Routes that cannot be unlocked not due to the turnaround operation, and all subsequent routes, will not be unlocked. For example, if a turnaround operation involves three basic routes: Route 1, Route 2, and Route 3, upon completion of the turnaround operation, if Route 1, which is closest to the turnaround signal, meets the one-time turnaround unlocking conditions, while Routes 2 and 3 do not, then only Route 1 will be unlocked at once; Routes 2 and 3 will not be unlocked at once. The method for determining if Routes 2 and 3 do not meet the conditions is the same as in condition 2 above.

[0141] It should also be noted that, for Figure 5 In the section without branch lines between the intermediate differential signals D354 and D348, if there are two cars simultaneously shunting in opposite directions, the following method can be used to prevent routes A and B from having a mutual reversal relationship that would prevent unlocking after route clearing: When routes A and B approach section clearing simultaneously, it can be determined that the section between routes A and B does not meet the unlocking conditions for sections that failed to unlock due to mid-way reversal operations. The unlocking fails in one go, and no further correlation checks are performed during periodic inspections. Following the normal three-point unlocking procedure, the route automatically unlocks after clearing.

[0142] In some embodiments, step S107, which unlocks sections that cannot be unlocked due to midway reversal, may include:

[0143] Step S1071: Determine the associated route of the shunting route;

[0144] Step S1072: Unlock the shunting route and the associated route.

[0145] In some embodiments, step S1071, determining the associated route of the shunting route, may include:

[0146] Determine whether the departure section of the shunting route coincides with the first section inside the signal of the searched route, and whether the departure section is not unlocked;

[0147] If it is determined that the departure section of the shunting route coincides with the first section inside the signal of the search route, and the departure section is not unlocked, then it is determined whether the approach section of the search route is occupied and has not been released from the shunting route.

[0148] If it is determined that the approach section of the search route is occupied and has not been released from the shunting route, then it is determined whether the signal cross-voltage status is normal.

[0149] If the signal cross-voltage status is determined to be normal, then the search route is set as the associated route of the shunting route.

[0150] In some embodiments, after setting the retrieval route as an associated route of the shunting route, the method further includes:

[0151] Traverse all segments of the associated path and determine whether there are any segments that have been released or occupied;

[0152] If it is determined that there is a released or occupied segment, then the associated path is canceled.

[0153] The process of determining the associated route of the shunting route in the above embodiments can be found in [reference needed]. Figure 8 , Figure 8 This describes the association method for unlocked sections as described in the standard, enabling trains to associate sections that could not be unlocked due to mid-journey turnaround operations all at once after fully entering the shunting route. Figure 9 The method shown is used for unlocking. This method does not require distinguishing between long shunting routes and basic shunting routes; it can connect sections that cannot be unlocked due to mid-journey turnaround operations, ensuring that... Figure 9 During the unlocking process, these sections can be unlocked all at once. Previously, the circuit method was used for unlocking, but it could not guarantee complete and correct identification of the associated sections of long shunting routes, resulting in missed unlocking and affecting operational efficiency. This method can ensure complete coverage of these associated sections and avoid the problem of missed unlocking.

[0154] like Figure 8As shown, this embodiment first sets a default return value and performs a shunting route legality check. If legal, the departure section ID of the route is obtained; otherwise, the process ends. If the departure section ID is legal, the existence of an associated route flag is set to non-existent. Then, the dynamic route table is traversed. If the departure section overlaps with the first section inside the signal of the route in Ganusson and the route is not unlocked, the existence of an associated route flag is set to exist, the connection / unconnection flag for the route is set to unconnect, and the flag indicating that the unlocked route requires connection or disconnection is set to no operation. Then, the current unlocking stage is determined. If the route has not entered the one-time unlocking stage, and if the route status requires connection or unconnection, the flag indicating that the unlocked route requires connection or disconnection is set to require operation. If the route enters the one-time unlocking stage and meets the one-time unlocking connection conditions, and if the route status requires connection, the flag indicating that the unlocked route requires connection or disconnection is set to require operation. For route unassociation operations, if the route is associated, the route association is removed; otherwise, the flag is cleared. For route association operations, if this operation is required and the approaching section of the route is not released from the route and is occupied, the signal cross-voltage is checked. If the signal cross-voltage is normal, the route is set as a turnaround associated route; otherwise, the route is set as not a turnaround associated route. Then, all sections on the route are traversed. If any section has been released from the route, the route is set as not a turnaround associated route. Next, a one-time unlocking section association check is performed. The sections on the route are traversed; if any section is occupied, the route is set as not a turnaround associated route. If the route needs connection association processing, this route is marked as a turnaround associated route, and the departing section of this route is used as the next search condition for the loop to associate the next route. If no associated turnaround route is found in this process, the processing flag is cleared.

[0155] In some embodiments, step S1072, which involves unlocking the shunting route and the associated route, may include:

[0156] When the turnaround signal is located inside the shunting route, if the section of the shunting route that overlaps with the section of the turnaround route is free, and the section of the shunting route that overlaps with the first section inside the turnaround route is occupied and released from the shunting route, then it is determined that the vehicle has completely entered the inside of the turnaround signal, and the section behind the turnaround signal is unlocked in one go; if there is no released and occupied section behind the turnaround signal, then it is determined that the unlocking conditions are met, and the section behind the turnaround signal is unlocked in one go.

[0157] When the turnaround signal is either the parallel signal or the differential signal, if the section of the shunting route that overlaps with the section of the turnaround route is free, and the section of the shunting route that overlaps with the first section inside the turnaround route is occupied and released from the shunting route, then it is determined that the vehicle has completely entered the inside of the turnaround signal, and the section behind the turnaround signal is unlocked in one go; it is then determined whether the signal cross-pressure status is normal; if it is determined that the signal cross-pressure status is normal, then it is determined whether there is a section behind the turnaround signal that has been released and is occupied; if it is determined that there is no section behind the turnaround signal that has been released and is occupied, then it is determined that the unlocking conditions are met, and the section behind the turnaround signal is unlocked in one go.

[0158] The unlocking process described in the above embodiments can be found in [reference needed]. Figure 9 ,pass Figure 9 The process allows for the simultaneous unlocking of sections that, as described in the standard, cannot be unlocked due to the operation during shunting turnaround. Figure 8 Association checking methods and Figure 7 The method for checking whether the cross-voltage is normal can prevent the circuit from being unable to determine whether there is one or two vehicles on the associated route, ensuring that only one vehicle is cross-voltaged on the unlocked section. This method, without adding detection equipment, uses logical operations to prevent the route of one vehicle from being mistakenly locked when there are two vehicles on two adjacent routes, thus ensuring driving safety.

[0159] like Figure 9As shown, this embodiment first sets a default return value and determines whether the route is valid. If invalid, the process ends; if valid, it determines whether the route is associated with a turnaround route. If the route itself is associated with a turnaround route, it obtains the index of the section of the turnaround route that overlaps with the current route and associates it with routes that cannot be unlocked due to shunting turnarounds. For the three different types of turnaround signals, the unlocking process specifically includes: for the case where the turnaround signal is inside the route, condition one is executed: if the section of the route that overlaps with the section of the turnaround route is free, and the section of the route that overlaps with the first section inside the turnaround route has been released from the route and is occupied, then it is determined that the vehicle has completely entered the turnaround signal and the section behind the turnaround signal is unlocked at once. Then, the sections of the route behind the turnaround signal are traversed. If the section is occupied and the section has been released from the route, then the route is set to not meet the unlocking conditions. If the approach section of the turnaround route is released and idle, the unlocking condition is not met, and the route association is cancelled. If the unlocking condition is met, the same method is used to check if the associated route meets the unlocking condition; if it does not, the route association is cancelled. For the case of parallel signals, the first condition is executed: if the section of the route that overlaps with the approach section of the turnaround route is idle, and the section of the route that overlaps with the first inner section of the turnaround route has been released from the route and is occupied, then it is determined that the vehicle has completely entered the inside of the turnaround signal, and the section behind the turnaround signal is unlocked at once. Then it is determined whether the cross pressure of the turnaround route is normal. If it is not normal, the route is set to not meet the unlocking condition. If it is normal, the sections of the route behind the turnaround signal are traversed. If the section is occupied and has been released from the route, the route is set to not meet the unlocking condition. If the approach section of the turnaround route is released and idle, the unlocking condition is not met, and the route association is cancelled. If the unlocking conditions are met, the associated route is checked using the same method. If the unlocking conditions are not met, the route association is cancelled. The case for differential signals is the same as for parallel signals, and will not be repeated here. It should be noted that... Figure 8 and Figure 9 For judging whether the transverse pressure is normal, please refer to Figure 7 The process is shown below.

[0160] The processing flow for shunting mid-journey turnaround operations in each cycle of the interlocking system operation in this embodiment is as follows: Figure 10 As shown, according to Figure 10 The program flow is designed to automatically identify and unlock routes. The system's computation module and shunting route unlocking module are loosely coupled, reducing development complexity. Specifically, the following steps are included:

[0161] Step S1001: Determine if a shunting route is required. In each cycle, the dynamic route table is searched sequentially for shunting routes, and step S1002 is executed for each shunting route.

[0162] Step S1002: Is there an associated turnaround signal along the route? Figure 2 The document details how to associate the turnaround signals of each route in the data. This step involves checking if there are any associated turnaround signals for the shunting route. If there are associated turnaround signals, proceed to step S1003. Otherwise, if there are no associated shunting turnaround routes for that route, proceed directly to the normal shunting route unlocking process. Its function is irrelevant to this application.

[0163] Step S1003: Is the turnaround signal open? To determine if there is a turnaround route requiring processing on the shunting route, it's necessary to ascertain whether the starting signal of any associated turnaround route is open during the normal unlocking process of the shunting route. The initial triggering condition for shunting turnaround service is the detection that the starting signal of an associated turnaround route is open, which triggers the shunting turnaround route processing procedure and proceeds to step S1004. This step is the core of this application; accurately determining whether the route has an associated turnaround route and whether this route meets the associated conditions is the key element for correctly unlocking the turnaround route.

[0164] Step S1004: Associate the route with its turnaround route and check whether the first section inside the turnaround route is occupied. This step is triggered by step S1003. When the turnaround signal in step S1003 is open, it is necessary to check whether the first section inside the turnaround route is occupied. If it is occupied, it means that the train has reversed. At this time, a shunting turnaround operation has been completed, and the route is checked according to step S1005.

[0165] Step S1005: The first section inside the turnaround route is occupied and nearing section clearance. This step will trigger a one-time unlocking of the section behind the turnaround route protection signal, step S1006. Unlocking of the turnaround route is carried out according to the requirements of the shunting route and is not within the scope of protection of this application.

[0166] Step S1006: Unlocking the section to be unlocked. When the system checks and confirms that the conditions of step S1005 are met, the section behind the route protection signal is unlocked in one go. The unlocking of the turnaround route itself is carried out according to the requirements of the shunting route, and this unlocking process is not within the scope of protection of this application.

[0167] Step S1007: Remove the routes to be unlocked from the route master table. This step means that after a route has been unlocked, it will be removed from the route master table (dynamic route table), marking the end of the entire shunting mid-journey unlocking process.

[0168] This application provides a software solution that completely replaces the 6502 circuit's mid-journey turnaround operation function. Without changing the existing positioning and communication methods, it proposes an improved method for unlocking mid-journey return and an automatic identification method for mid-journey turnaround routes. This achieves a purely software logic processing procedure for identifying and unlocking mid-journey return routes under fully electronic interlocking conditions, technically solving the problem of complex judgment logic and difficulty in implementation in unlocking mid-journey return.

[0169] This application can achieve the following technical effects:

[0170] 1. The method adopted enables the system to automatically identify and unlock shunting turnaround routes through software logic within the fully electronic interlocking system architecture.

[0171] 2. The fault handling mechanism adopted ensures that the software implementation scheme can realize the function of shunting turnaround without reducing safety.

[0172] 3. The design approach adopted ensures low coupling between software functions and other approach functions, and provides a method for sharing data.

[0173] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0178] The first judgment unit 1103 is used to determine whether the turnaround signal is in an open state if a turnaround signal associated with the shunting route is detected.

[0179] The second judgment unit 1104 is used to determine whether the route with the turnaround signal as the starting signal is the turnaround route of the shunting route if the turnaround signal is in the open state.

[0180] The association unit 1105 is used to associate the shunting route with the turnaround route if it is determined that the route with the turnaround signal as the starting signal is the turnaround route of the shunting route, wherein the turnaround route is the route with the turnaround signal as the starting signal.

[0189] The second determining submodule is used to determine the following if, when the protection direction of the shunting route is to the left, the left section of the turning signal coincides with the approach section of the shunting route: if so, the turning signal is the differential signal; if the right section of the turning signal coincides with the approach section of the shunting route: if so, the turning signal is the parallel signal; and if there is a valid section in the shunting route that coincides with the approach section of the turning signal, the turning signal is the signal located inside the shunting route.

[0190] In some embodiments, the associated module includes:

[0191] The first association submodule is used to associate the shunting route with the turnaround route if, when the turnaround signal is the signal located inside the shunting route, the approach section of the turnaround route is occupied, the first section inside the turnaround signal is occupied and has been released from the shunting route.

[0192] The second association submodule is used to determine whether the signal cross-voltage status is normal when the turnaround signal is the parallel signal or the differential signal, and the approach section of the turnaround route is occupied, the first section inside the turnaround signal is occupied and has been released from the shunting route; if the signal cross-voltage status is determined to be normal, then the shunting route is associated with the turnaround route.

[0193] In some embodiments, determining whether the trans-voltage state of the signal is normal includes:

[0194] Detect whether there is a signal on the first section inside the shunting route and whether it has been released from the shunting route;

[0195] If there is a signal on the first section inside the shunting route and it has not been released from the shunting route, then it is determined whether the existing signal is in an open state.

[0196] If the existing signal is in an open state, and both the first section inside the shunting route and the adjacent section of the shunting route are occupied, then the signal cross-pressure status is determined to be normal.

[0197] In some embodiments, the unlocking unit 1107 includes:

[0198] The second determining module is used to determine the associated routes of the shunting route;

[0199] The unlocking module is used to unlock the shunting route and the associated route.

[0200] In some embodiments, the second determining module includes:

[0201] The first judgment submodule is used to determine whether the departure section of the shunting route coincides with the first section inside the signal of the search route, and whether the departure section is not unlocked.

[0202] The second judgment submodule is used to determine whether the approach section of the shunting route is occupied and has not been released from the shunting route if it is determined that the departure section of the shunting route coincides with the first section inside the signal of the search route and the departure section is not unlocked.

[0203] The third judgment submodule is used to determine whether the signal cross-voltage status is normal if it is determined that the approach section of the search route is occupied and has not been released from the shunting route.

[0204] The setting submodule is used to set the search route as the associated route of the shunting route if it is determined that the signal cross-voltage status is normal.

[0205] In some embodiments, the second determining module further includes:

[0207] The Cancel submodule is used to cancel the setting of the associated path if it is determined that there is a released or occupied segment.

[0208] In some embodiments, the unlocking module includes:

[0209] The first unlocking submodule is used to determine, when the turnaround signal is the signal located inside the shunting route, that if the section of the shunting route that overlaps with the section of the turnaround route is free, and the section of the shunting route that overlaps with the first section inside the turnaround route is occupied and released from the shunting route, then the vehicle is determined to have completely entered the inside of the turnaround signal, and the section behind the turnaround signal is set to be unlocked in one go; if there is no section behind the turnaround signal that is both released and occupied, then the unlocking conditions are determined to be met, and the section behind the turnaround signal is unlocked in one go.

[0210] The second unlocking submodule is used when the turnaround signal is either the parallel signal or the differential signal. If the section of the shunting route that overlaps with the section of the turnaround route is free, and the section of the shunting route that overlaps with the first section inside the turnaround route is occupied and released from the shunting route, then it is determined that the vehicle has completely entered the inside of the turnaround signal, and the section behind the turnaround signal is unlocked in one go. The module also determines whether the signal cross-pressure status is normal. If the signal cross-pressure status is normal, it determines whether there is a section behind the turnaround signal that has been released and is occupied. If there is no section behind the turnaround signal that has been released and is occupied, then the unlocking conditions are met, and the section behind the turnaround signal is unlocked in one go.
