Description

Technical Field

[0001] The embodiments of this specification relate to the field of rail transit technology, and in particular to a method, device and system for locking a protection section across an interlocking route. Background Art

[0002] With the rapid development of computer technology and intelligent control technology, urban rail transit lines are becoming more and more complex. Interconnection can realize the control between different lines and is an important part of the rail transit system. In the rail transit system, the protection section is a repeated section set outside the approach to prevent the train from side collision or head-on collision. When the train advances due to the driver's wrong operation outside the stop signal or insufficient train braking performance, the possibility of conflict between the advancing train and the normal operating train is reduced.

[0003] In terms of the interconnection of the interlocking system, due to the different interlocking interfaces of different lines and manufacturers, when it comes to handling the route at the demarcation point, the locking problem of the protection section will be involved. Since the route information is no longer transmitted between adjacent interlockings, the interlocking where the protection section is located cannot lock the protection section for the adjacent interlocking where the route is located, resulting in the protection section of the route not being locked normally, causing abnormalities in the route handling. Therefore, a locking solution for the protection section across interlocking routes is urgently needed. Summary of the invention

[0046] In addition, it should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0047] First, the terms involved in one or more embodiments of this specification are explained.

[0048] Interlocking System (CI): refers to the mutual restriction relationship established between signal machines, turnouts and routes through technical means in order to ensure the safety of railway station operation and shunting operations. The interlocking system is a key component of the subway signal system. Its main function is to control and manage the signals, turnouts, routes, etc. on the line. It uses a two-by-two safety computer platform to realize the correct interlocking restriction relationship between station equipment, select routes for trains running in its control area, and ensure the safe operation of trains. The interlocking relationship between signal machines, turnouts and routes mainly includes: if the turnout position is incorrect, the route is not cleared, and there is a car occupying the route, the signal machine protecting the route cannot open the permission signal; once the signal opens the permission signal, the route is locked, and the position of the turnout on the route is not allowed to be changed. The protection signal of the hostile route (the route that is not allowed to be established at the same time) is also locked in the closed state. When a train or train enters the route, the signal machine will automatically close immediately and cannot be automatically opened again. Obviously, interlocking exists between two objects, such as: between a switch and a signal, between opposing signals, between an approach and a signal, etc.

[0049] Interoperability: In the field of rail transit, interconnection usually refers to the ability to achieve seamless connection and data exchange between different rail transit systems, including the collaborative work between different subway lines, rail transit systems in different cities, and even railway systems in different countries. Interlocking between different lines and different manufacturers interacts through agreed interfaces, using the interoperability protocol. The goal of interconnection is to improve transportation efficiency, enhance passenger experience, and optimize operating costs.

[0050] Route: The section of route that a train or shunting train passes through when running from one designated location to another designated location.

[0051] Approach processing: After the interlocking receives the route processing command from the upper computer, the interlocking host selects the pending route and performs a consistency check on the route selection. After the check passes, the route is locked and the permission signal is released. The train enters the route according to the permission signal.

[0052] Axle counting section: Track circuits are generally no longer set up on urban rail main lines. Instead, axle counters are used to complete train section occupancy checks. Axle counters are used to divide the line into logically insulated sections, which are called axle counting sections.

[0053] Physical section: A closed section consisting of axle counting sections. For sections with switches, the physical section contains multiple axle counting sections.

[0054] Protection section: In the signal system, the protection section is set up outside the route to prevent the train from side collision or head-on collision. It reduces the possibility of conflict between the advancing train and the normal operating train when the train advances due to the driver's erroneous operation outside the stop signal or insufficient braking performance of the train.

[0055] Locking: In order to ensure the safe operation of trains, a technical means is used to limit signals, switches, sections and routes to a specified state through an interlocking system.

[0056] Unlocking: When the interlocking system checks that the unlocking conditions are met, the restricted status of signals, switches, sections and routes is released.

[0057] In this specification, a method for locking a protection section across an interlocking approach is provided. This specification also relates to another method for locking a protection section across an interlocking approach, a protection section locking device across an interlocking approach, another protection section locking device across an interlocking approach, a protection section locking system across an interlocking approach, a computing device, a computer-readable storage medium, and a computer program product, which are described in detail one by one in the following embodiments.

[0058] See also Figure 1 , Figure 1 A flow chart of a method for locking a protection section across an interlocking route provided according to an embodiment of the present specification is shown, which is applied to the first interlocking and specifically includes the following steps.

[0059] Step 102: Acquire a terminal signal machine of a cross-interlocking route, and configure the terminal signal machine in the first interlocking machine, wherein the terminal signal machine is a signal machine included in the second interlocking machine.

[0060] It should be noted that the interconnection can include two adjacent interlocking systems, the first interlocking and the second interlocking, which manage their corresponding lines respectively. A cross-interlocking route refers to a route to which the interlocking to which the protection section belongs is different from the interlocking to which the route belongs, that is, the route and the protection section are controlled by two adjacent interlocking systems. In this case, the cross-interlocking route belongs to the first interlocking, but the terminal signal of the cross-interlocking route belongs to the second interlocking.

[0061] For example, Figure 2 This is a schematic diagram of a circuit under interconnection provided by an embodiment of this specification, such as Figure 2 As shown, route S1-S2 is the route controlled by the first interlocking CI1, physical section P1 is the protection section of route S1-S2, S2 is the terminal signal of route S1-S2, terminal signal S2 belongs to the second interlocking CI2, and physical sections P2 and P3 included in route S1-S2 belong to the first interlocking CI1. Route S1-S2 is a cross-interlocking route, and the protection section P1 of route S1-S2 crosses the interlocking area.

[0062] It should be noted that the terminal signal of the cross-interlocking route belongs to the second interlocking, and the route information is no longer transmitted between adjacent interlocking systems on the interconnected lines, resulting in the second interlocking being unable to lock the protection section for the cross-interlocking route of the first interlocking, causing the cross-interlocking route to be unable to be opened.

[0063] Therefore, in the embodiments of the present specification, a terminal signal across the interlocking route can be configured in both the first interlocking and the second interlocking. That is, although the terminal signal is a signal included in the second interlocking, the terminal signal is also configured in the first interlocking, and is used to send a protection section application command and obtain a protection section validity flag updated by the second interlocking, so that the first interlocking and the second interlocking can interact through the terminal signal across the interlocking route, thereby realizing the locking of the protection section across the interlocking route.

[0064] In actual implementation, configuring the terminal signal in the first interlocking means configuring the signal identification of the terminal signal of the cross-interlocking route in the first interlocking, and the interactive logic of writing and reading data based on the signal identification, such as writing the application locking command of the target protection section into the data area corresponding to the signal identification of the terminal signal, and the second interlocking can obtain the corresponding application locking command written by the first interlocking based on the signal identification, or the first interlocking can read the protection section validity flag written by the second interlocking based on the signal identification, so that the first interlocking can interact with the second interlocking based on the terminal signal. Among them, the protection section validity flag is used to indicate whether the second interlocking has successfully established the corresponding protection section for the cross-interlocking route of the first interlocking. The second interlocking can obtain the protection section validity flag corresponding to the terminal signal to know whether the second interlocking has successfully established the corresponding protection section, and realize the protection section locking under interconnection and interoperability.

[0065] Continuing with the above example, the route information is no longer transmitted between the adjacent interlockings CI1 and CI2 of the interconnected lines, resulting in CI2 being unable to lock the protection section P1 for the route S1-S2 of CI1, and the route S1-S2 cannot be opened. The terminal signal S2 is a signal included in CI2. In the embodiment of this specification, the terminal signal S2 of the route S1-S2 can also be configured in the adjacent interlocking CI1, so that the adjacent interlockings CI1 and CI2 are both configured with the terminal signal S2, and the adjacent interlockings CI1 and CI2 can both achieve the locking of the protection section based on the identification of the terminal signal S2. Specifically, CI1 can configure a protection section application command under the terminal signal S2, so that CI2 establishes a protection section for CI1 based on the protection section application command, and configures a protection section validity flag under the terminal signal S2. CI1 can obtain the protection section validity flag configured under the terminal signal S2 based on the identification of the terminal signal S2, thereby achieving CI2 locking the protection section P1 for the route S1-S2 of CI1.

[0066] In the embodiments of the present specification, a terminal signal belonging to the second interlocking and the cross-interlocking route can be configured in the first interlocking. Subsequently, the first interlocking can send a protection section application command to the second interlocking through the terminal signal, so that the second interlocking locks the corresponding protection section for the cross-interlocking route of the first interlocking. The first interlocking can also obtain the update of the second interlocking through the terminal signal and write the protection section validity flag of the terminal signal, so as to know whether the second interlocking has successfully established the corresponding protection section, thereby realizing the locking of the protection section under interconnection and interoperability.

[0067] Step 104: Periodically obtain the protection section locking flag of the cross-interlocking route, wherein the protection section locking flag is a flag indicating whether the cross-interlocking route has successfully established the protection section.

[0068] Among them, the protection section locking flag can be set to be locked or not set to be locked. Set to be locked is used to indicate that the corresponding cross-interlocking approach has successfully established a protection section and the approach can be processed; not set to be locked is used to indicate that the corresponding cross-interlocking approach has not successfully established a protection section and the approach cannot be processed.

[0069] In actual implementation, the protection section locking flag of the cross-interlocking route can be periodically obtained to determine whether the cross-interlocking route has successfully established the protection section, and then determine whether to perform subsequent inspection operations.

[0070] It should be noted that the first interlocking may include multiple routes, some of which belong to the routes controlled by the first interlocking, and the first interlocking can realize the locking of the protection section, while some routes belong to the cross-interlocking routes under the interconnection, and the adjacent second interlocking needs to lock the corresponding protection section for the first interlocking. Therefore, specifically, the first interlocking can traverse each route, and if it is the route of this interlocking, directly use the method of its own interlocking to lock the corresponding protection section; if it is not the route of this interlocking, determine whether it is the route of the same line. If so, it means that it is an adjacent route of its own interlocking, and use the logic of locking the protection section between its own interlocking stations; if it is not the route of this interlocking and does not belong to the route of the same line, it means that it is an interlocking route between interconnecting stations, then the route is determined as a cross-interlocking route, interacts with the second interlocking, and locks the corresponding protection section through interconnection.

[0071] In an optional implementation of this embodiment, after periodically acquiring the locking flag of the protection section across the interlocking route, the method further includes:

[0072] If the protection section locking flag is not set to lock, then traverse each protection section, and determine whether each protection section meets the locking establishment conditions according to each physical section and conditional turnout of each protection section;

[0073] If any protection section meets the lock establishment conditions, the protection section lock flag will be updated to lock set.

[0074] The locking establishment condition refers to that each physical section of the protection section is locked successfully and the included conditional turnout is not located at the specified position.

[0075] In rail transit systems, turnouts (also known as switches) are a key railway infrastructure used to guide trains from one track to another. Turnouts are usually composed of a set of movable parts that can change the direction of the track to guide trains into different lines. The design and operation of turnouts are essential to ensure the safe and efficient operation of trains. Conditional turnouts are turnouts that can only be used under certain conditions. These conditions are usually set to ensure the safety of trains and avoid conflicts. The concept of conditional turnouts appears more often in complex interlocking systems, especially when multiple factors need to be considered to determine the position of the turnout.

[0076] Specifically, the locking establishment condition is a pre-configured checking rule used to constrain the physical sections of the protection section and the conditional switches under what circumstances the protection section has been successfully established. Therefore, based on the locking establishment condition, it can be checked whether there is a protection section in the cross-interlocking route that has been successfully established, but the protection section locking flag has not been updated.

[0077] It should be noted that the first interlocking can periodically obtain the protection section locking flag of the cross-interlocking route. If the protection section locking flag is set to locked, it means that the cross-interlocking route has successfully established the protection section and can be processed. At this time, the loop ends and the protection section locking flag of the cross-interlocking route is no longer obtained. If the protection section locking flag is not set to locked, it means that the cross-interlocking route has not successfully established the protection section. At this time, the protection sections of the cross-interlocking route can be traversed, and according to the physical sections and conditional switches of each protection section, it is determined whether each protection section meets the locking establishment conditions. If any protection section meets the locking establishment conditions, it means that any protection section has been successfully established. At this time, the first interlocking can update the protection section locking flag of the cross-interlocking route to set locked. In actual implementation, the route to which the protection section locking flag of the cross-interlocking route belongs can be configured as the route identifier of the cross-interlocking route.

[0078] In the embodiments of the present specification, even if the protection section locking flag indicates that the lock is not set, the second interlocking is not directly requested to lock the protection section. Instead, each protection section is traversed to determine whether there is a protection section that has been successfully established but the protection section locking flag has not been updated. If any protection section meets the locking establishment conditions, it means that a protection section has been successfully locked. At this time, the protection section locking flag of the cross-interlocking approach can be updated to set locked, thereby avoiding the need to apply for the establishment of a protection section again for the cross-interlocking approach that has already established a protection section, resulting in abnormal approach processing, and improving the accuracy of the protection section locking operation under intercommunication.

[0079] In an optional implementation of this embodiment, determining whether each protection section meets the locking establishment condition according to each physical section and conditional turnout of each protection section includes:

[0080] Determine whether each physical section is locked successfully according to the locking status of each physical section of the first protection section, wherein the first protection section is any one of the protection sections across the interlocking route;

[0081] If each physical section is locked successfully, determine whether the conditional turnout contained in the first protection section is located at the specified position. If so, determine that the first protection section meets the locking establishment conditions; if not, determine that the first protection section does not meet the locking establishment conditions, and continue to traverse the next protection section across the interlocking route.

[0082] Specifically, the pre-configured locking establishment condition is that each physical section of the protection section is locked successfully, and the conditional turnout contained in the protection section is located at a specified position. Among them, the successful locking of each physical section includes that the route to which the protection lock belongs is greater than 0 and the locking direction is the same as the route direction.

[0083] In actual implementation, the physical sections of the first protection section can be traversed to obtain the locking status of each physical section. If the locking status of each physical section contained in the first protection section indicates that the route to which its protection locking belongs is greater than 0 and the locking direction is the same as the direction of the cross-interlocking route, it means that the physical sections of the first protection section have been successfully locked by the cross-interlocking route; at this time, it is further determined whether the conditional turnout contained in the first protection section is located at the specified position. If so, it is determined that the first protection section meets the locking establishment conditions; if not, it is determined that the first protection section does not meet the locking establishment conditions, and the next protection section of the cross-interlocking route is continued to be traversed. If the physical sections of the first protection section are not successfully locked, the next protection section of the cross-interlocking route is continued to be traversed. Among them, continuing to traverse the next protection section of the cross-interlocking route means taking the next protection section as the first protection section, and continuing to execute the steps of determining whether each physical section is successfully locked according to the locking status of each physical section of the first protection section, until all protection sections of the cross-interlocking route are traversed.

[0084] In the embodiments of the present specification, it is possible to determine whether each physical section has been locked and whether the locking direction is the same as the direction of the cross-interlocking route based on the locking status of each physical section of the first protection section, so as to judge whether each physical section has been successfully locked. In the case of successful locking, the position of the conditional turnout can be further checked to determine whether the first protection section meets the locking establishment conditions, thereby avoiding misjudgment and ensuring high judgment accuracy.

[0085] In an optional implementation of this embodiment, before periodically acquiring the locking flag of the protection section across the interlocking route, the method further includes:

[0086] Determine whether the interlocking to which the first signal belongs and the first interlocking are on the same line, wherein the first signal is any one of the signals configured for the first interlocking;

[0087] If they are not the same line, the protection section validity flag associated with the first signal will be initialized to lock invalid.

[0088] It should be noted that each signal configured in the first interlocking can also be initialized. Specifically, the first interlocking can obtain each signal configured in this interlocking, including each signal belonging to the first interlocking and the second interlocking, and determine whether the interlocking to which each signal belongs and this interlocking are on the same line. If they are on the same line, the interlocking to which the signal of the first physical section outside the signal belongs can be obtained, and then it can be determined whether the interlocking to which the signal of the first physical section belongs is on the same line as the first interlocking. If they are on the same line, it means that the protection section associated with the signal belongs to the first interlocking, and the validity flag of the protection section associated with the signal can be set to valid, and the first interlocking can be directly checked and processed to realize the locking of the protection section. If not, and the guidance is safe, it can be set to invalid. If the interlocking to which the signal belongs and this interlocking are not on the same line, it means that the signal belongs to the interconnection control, that is, the signal belongs to the adjacent second interlocking, and the protection section validity flag is set to invalid by default, and then the second interlocking can update the protection section validity flag.

[0089] In the embodiments of the present specification, the validity flags of the protection sections associated with the interconnected signal machines in the first interlocking can be initialized to invalid, so that the subsequent second interlocking can perform a conditional check, and after the first interlocking machine locks the protection section, the validity flag of the protection section is updated to invalid. Thus, the interaction between the first interlocking and the second interlocking can be achieved through the validity flags of the protection sections associated with the signal machines, thereby achieving the locking of the protection sections of the interconnected cross-interlocking route.

[0090] Step 106: When the locking flag of the protection section indicates that locking is not set, and the protection sections across the interlocking route do not meet the locking establishment conditions, determine whether each protection section meets the locking application conditions, where failure to meet the locking establishment conditions means that the physical sections of the protection section are not locked successfully or are locked successfully but the conditional turnouts included are not located at the specified position, and the locking application conditions are used to check whether each protection section can apply for locking to the second interlocking.

[0091] Among them, the lock application condition is a pre-configured inspection rule.

[0092] It should be noted that the first interlocking can periodically obtain the locking flag of the protection section across the interlocking route. If the locking flag of the protection section is not set, then the various protection sections of the cross-interlocking route can be traversed to determine whether the various protection sections of the cross-interlocking route meet the locking establishment conditions. If none of the protection sections of the cross-interlocking route meet the locking establishment conditions, it can be further determined whether the various protection sections of the cross-interlocking route meet the locking application conditions, thereby applying to the second interlocking to lock the qualified protection sections.

[0093] In actual implementation, the first interlocking can obtain the data of each associated protection section according to the terminal signal of the cross-interlocking route to determine whether each protection section meets the locking application conditions. In other words, the second interlocking can transmit the data of each associated protection section to the first interlocking through the terminal signal, so that the first interlocking can check whether each protection section can apply for locking. If the protection section includes a turnout, the turnout position can also be transmitted to the first interlocking through the terminal signal, so that the first interlocking can check whether the turnout position associated with the protection section is correct.

[0094] In an optional implementation of this embodiment, determining whether each protection zone meets the lock application condition includes:

[0095] Check whether the last physical section of the cross-interlocking route is free, check whether the last physical section of the cross-interlocking route is locked normally and belongs to the cross-interlocking route, check that all physical sections in the second protection section are not locked, check that all physical sections in the second protection section are free, check that all physical sections in the second protection section are not requisitioned, check that all physical sections in the second protection section are not locked or are normally locked or protectively locked in the same direction as the cross-interlocking route, check that the intrusion section and conditional turnouts in the second protection section meet the specified position, check that the hostile intrusion section of the second protection section is not locked, check that each turnout in the second protection section does not guide the main lock, check that the turnouts and protective turnouts in the second protection section are not locked, and check that each physical section in the second protection section is not jump-locked, wherein the second protection section is any one of the protection sections of the cross-interlocking route;

[0096] If all the above checks are passed, it is determined that the second protection zone meets the lock application conditions;

[0097] If any of the checks fails, it is determined that the second protection section does not meet the lock application conditions, and the next protection section is traversed.

[0098] Among them, the restricted section is when a train or other object enters an area that it should not enter, or exceeds its permitted operating range, which may cause safety risks, such as collisions with other trains, collisions with trackside facilities, or interference with normal operations. The hostile restricted section, also known as the "hostile approach" or "conflicting approach", refers to the potential conflict between two or more train paths within a track approach, that is, if these paths are activated at the same time, they may cause train collisions or other safety problems. This usually occurs when the signal system and interlocking system fail to properly manage the train path. The guide master lock, also known as the master guide lock or master locking, is a safety mechanism used to lock all related turnouts and signals under specific circumstances to prevent any train from entering a specific area. The protective turnout, also known as the protection turnout or safety turnout, is an important safety measure used to prevent trains from entering paths that may conflict with other trains. The main purpose of the protective turnout is to ensure the safety of train operation, especially in the case of complex track layouts and multiple path selections. Jump locking, also known as jump locking or jump locking, is a safety mechanism. When a train approaches or enters a switch section, the switch will be locked in its current position until the train has completely passed through the section. It is used to prevent the train from passing through the switch due to sudden changes in the switch position. Danger, jump locking ensures that the switch does not move unexpectedly when the train passes, thereby avoiding derailment or other safety accidents.

[0099] It should be noted that any one of the protection sections across the interlocking route is selected as the second protection section, and the above-mentioned inspection is performed on the second protection section. If the above inspections are passed, it is determined that the second protection section meets the locking application conditions and can apply for locking to the second interlocking; if any inspection fails, it is determined that the second protection section does not meet the locking application conditions, and the traversal of the next protection section continues, that is, the next protection section among the protection sections across the interlocking route is selected as the second protection section, and the above-mentioned inspection is continued until all the above inspections of any protection section are passed, the traversal is terminated, or the traversal of each protection section across the interlocking route is completed.

[0100] In the embodiments of this specification, it is possible to determine whether each protection section meets the locking application conditions through a variety of inspection conditions. The inspection dimensions are comprehensive, which improves the accuracy of applying for locking to the second interlocking, avoids erroneous applications for protection sections that cannot be locked for the cross-interlocking approach, and causes failures or accidents, thereby improving the accuracy and safety of locking protection sections under interconnection.

[0101] Step 108: If the target protection section meets the locking application conditions, the terminal signal configured by itself sends a locking application command for the target protection section to the second interlocking, wherein the target protection section is any one of the protection sections across the interlocking route, and the second interlocking is the adjacent interlocking of the first interlocking. The locking application command is used to instruct the second interlocking to lock the target protection section across the interlocking route and update the protection section validity flag.

[0102] It should be noted that if any of the protection sections of the cross-interlocking route, that is, the target protection section, meets the locking application conditions, the first interlocking can write the application locking command of the target protection section into the data corresponding to the terminal signal of the cross-interlocking route through the terminal signal. After the second interlocking detects the application locking command of the terminal signal, it can check and lock the target protection section for the cross-interlocking route if the conditions are met, and update the protection section validity flag of the terminal signal. The first interlocking can obtain the protection section validity flag based on the terminal signal, thereby determining whether the second interlocking has locked the target protection section for its own cross-interlocking route.

[0103] In the embodiments of this specification, if any protection section meets the locking application conditions, an attempt can be made to lock the protection section, and an application locking command for the target protection section is sent to the interlocking (second interlocking) where the protection section is located through the terminal signal of the cross-interlocking route, so as to apply to the second interlocking to lock the target protection section for the cross-interlocking route, thereby realizing the locking of the protection section under interconnection and interoperability.

[0104] In an optional implementation of this embodiment, after the terminal signal configured by itself sends a lock application command of the target protection section to the second interlocking, the method further includes:

[0105] According to the terminal signal of the cross-interlocking route, obtain the protection section validity flag returned by the second interlocking;

[0106] If the protection section validity flag is locked, the protection section locking flag is updated to locked.

[0107] In actual implementation, for the first interlocking, the terminal signal of the cross-interlocking route is not the signal of this interlocking. The first physical section outside the terminal signal belongs to the first interlocking, which means that the terminal signal is a cross-station interlocking signal. The first interlocking needs to parse the protection section validity flag sent by the second interlocking through the terminal signal. If the protection section validity flag is valid for locking, the protection section locking flag is updated to locked. If other opening conditions are met, the cross-interlocking route can be opened, otherwise it will not be opened.

[0108] It should be noted that the first interlocking obtains the protection section validity flag returned by the second interlocking based on the terminal signal of the cross-interlocking route, and updates the protection section locking flag based on the locking status of the protection section, thereby realizing the development of the cross-interlocking route, ensuring that the protection section of the cross-interlocking route can be locked normally under interconnection and intercommunication, realizing the processing of the cross-interlocking route, and ensuring the stability of the interconnection and intercommunication system.

[0109] For example, Figure 3 This is a flowchart of a first interlocking application locking protection section provided by an embodiment of this specification, such as Figure 3 As shown, the first interlocking obtains the protection section across the interlocking route, and determines whether the protection section across the interlocking route needs to be locked. If it does not need to be locked, no processing is performed and the process ends.

[0110] If locking is required, the first interlocking periodically obtains the locking flag of the protection section across the interlocking route, and determines whether the protection section across the interlocking route is unlocked based on the locking flag of the protection section (specifically, if the locking flag of the protection section indicates that locking has been set, it means that it has been locked; if the locking flag of the protection section indicates that locking has not been set, it means that it is unlocked).

[0111] If it is already locked, then end. If it is not locked, then traverse each physical section of each protection section to determine whether the locking status of each physical section indicates that its protective locking route is greater than 0 and the locking direction is the same as the direction of the cross-interlocking route. If so, then determine whether the conditional turnout contained in the protection section is located at the specified position. If it is located at the specified position, then determine that the protection section meets the locking establishment conditions, and update the locking flag of the protection section to set locked. Among them, if any of the conditions is not met, it is determined that the protection sections of the cross-interlocking route do not meet the locking establishment conditions, and each protection section is traversed to see whether it meets the locking application conditions. Whether it meets the locking application conditions may include the following checks: check whether the last physical section of the cross-interlocking route is idle, check whether the last physical section of the cross-interlocking route is locked normally and belongs to the cross-interlocking route, check whether all physical sections in the protection section are unlocked, check that all physical sections in the protection section are idle, check that all physical sections in the protection section are not requisitioned, check that all physical sections in the protection section are unlocked or are normally locked or protectively locked in the same direction as the cross-interlocking route, check that the intrusion section and conditional switches in the protection section meet the specified position, check that the hostile intrusion section of the protection section is not locked, check that each switch in the protection section does not guide the main lock, check that the switches and protective switches in the protection section are not locked, and check that each physical section in the protection section is not jump-locked.

[0112] Determine whether the above checks are all passed. If so, obtain the terminal signal of the cross-interlocking route, send the application lock command of the protection section to the second interlocking through the terminal signal of the cross-interlocking route, and exit the loop. If not, continue to traverse the next protection section.

[0113] The embodiments of the present specification provide a method for locking a protection section of a cross-interlocking approach, which is applied to a first interlocking, and a terminal signal of a cross-interlocking approach is configured in the first interlocking. When the locking flag of the protection section indicates that locking is not set, and the protection sections of the cross-interlocking approach do not meet the locking establishment conditions, it indicates that the cross-interlocking approach has not yet established a protection section. At this time, it can be further determined whether the protection sections of the cross-interlocking approach meet the locking application conditions. If any protection section meets the locking application conditions, a locking application command for the protection section is sent to the second interlocking through the terminal signal of the cross-interlocking approach, so as to establish a protection section for the cross-interlocking approach through the second interlocking, thereby realizing the locking of the protection section of the cross-interlocking approach between adjacent interlockings under interconnection, and ensuring that the cross-interlocking approach can be handled normally under interconnection.

[0114] See also Figure 4 , Figure 4 A flow chart of another method for locking a protection section across an interlocking route provided according to an embodiment of the present specification is shown, which is applied to the second interlocking and specifically includes the following steps.

[0115] Step 402: Obtain a locking application command of a target signal, wherein the target signal is a signal included in the second interlocking, and the target signal is a terminal signal of a cross-interlocking route configured in the first interlocking, and the locking application command is initiated by the first interlocking through the target signal, and the first interlocking is an adjacent interlocking of the second interlocking.

[0116] It should be noted that the second interlocking can traverse all the signal lights configured by itself. If it is not a signal light controlled by this interlocking, it means that it may be a signal light controlled by other adjacent interlocking lights and no processing will be performed. If it is a signal light controlled by this interlocking, it can be determined whether the signal light has a locking request command sent by an adjacent interlocking.

[0117] In one implementation, the first interlocking initiates an application locking command for the target protection section through the terminal signal across the interlocking route. When the second interlocking traverses to the terminal signal, it is the signal controlled by this interlocking and there is an application locking command initiated by the adjacent first interlocking. At this time, the terminal signal is the target signal. The second interlocking can subsequently process the application locking command of the terminal signal to lock the corresponding protection section across the interlocking route of the first interlocking.

[0118] In an optional implementation of this embodiment, after obtaining the lock application command of the target signal, the method further includes:

[0119] Obtain the protection direction of the target signal and each protection zone associated with the target signal;

[0120] According to the protection direction of the target signal and the protection sections associated with the target signal, determine whether the lock application command of the target signal is valid and whether the data of each protection section is valid;

[0121] If valid, then traverse each protection section associated with the target signal to determine whether each protection section is a section included in the second interlocking.

[0122] In actual implementation, the lock application command is used to apply for the second interlocking to lock the target protection section corresponding to the cross-interlocking route. However, due to the protection direction of the target signal, the direction of the cross-interlocking route, and the data of each protection section itself (such as the switch position), it may be impossible to respond to the lock application command. Specifically, the second interlocking can obtain the protection direction of the target signal and the protection sections associated with the target signal; according to the protection direction of the target signal and the protection sections associated with the target signal, determine whether the lock application command of the target signal is valid and whether the data of each protection section is valid. If valid, traverse the protection sections associated with the target signal to determine whether each protection section is a section included in the second interlocking, so as to process the protection sections included in this interlocking.

[0123] In the embodiment of this specification, the second interlocking can first determine the validity of the application locking command, and then perform locking processing on the protection section included in this interlocking, avoiding responding to invalid application locking commands, improving the accuracy of locking the protection section, and saving processing resources.

[0124] Step 404: When the target protection section to be locked indicated by the locking command is a section included in the second interlocking, check whether the target protection section meets the locking condition.

[0125] Among them, the locking condition is a pre-configured rule used to check whether the protection section can be locked for the corresponding cross-interlocking route.

[0126] It should be noted that the second interlocking can traverse various protection sections associated with the target signal, and check whether the protection sections belonging to the second interlocking meet the locking conditions.

[0127] In an optional implementation of this embodiment, checking whether the target protection section meets the locking condition includes:

[0128] Check that all physical sections within the target protection section are not locked, check that all physical sections within the protection section are free, check that all return routes within the target protection section are free, check that the intrusion section and conditional turnouts within the target protection section meet the specified position, check that the hostile intrusion section of the target protection section is not locked, check that all turnouts within the target protection section are not guided by the main lock, check that the turnouts and protective turnouts within the target protection section are not locked, check that all physical sections within the target protection section are not locked or are normally locked or protectively locked in the same direction as the route across the interlocking route, check that the position of each turnout within the target protection section is correct or the turnout position is incorrect but can be moved, check that the turnout position of each conditional turnout in the target protection section is correct, and check that all physical sections within the target protection section are not jumped and locked;

[0129] If all the above checks are passed, it is determined that the target protection section meets the locking conditions;

[0130] If any of the checks fails, it is determined that the target protection section does not meet the locking conditions.

[0131] It should be noted that for the target protection section that is locked by the locking command application, the above-mentioned checks can be performed in sequence. If all the above checks are passed, it is determined that the target protection section meets the locking conditions, and the second interlocking can lock the target protection section for the cross-interlocking approach of the first interlocking; if any check fails, it is determined that the target protection section does not meet the locking conditions, the target protection section is not locked, and the processing is terminated.

[0132] In the embodiments of this specification, a variety of inspection conditions can be used to determine whether the target protection section meets the locking conditions. The inspection dimensions are comprehensive, which improves the accuracy of the second interlocking locking of the protection section, avoids incorrect locking of the protection section, resulting in failures or accidents, and improves the accuracy and safety of locking the protection section under interconnection.

[0133] Step 406: If the locking conditions are met, the target protection section is locked for the cross-interlocking route, the protection section validity flag is updated to lock valid, and the updated protection section validity flag is returned to the first interlocking through the target signal, wherein the protection section validity flag is used by the first interlocking to update the protection section locking flag of the cross-interlocking route.

[0134] It should be noted that, for the second interlocking, it can obtain the application lock command sent by the adjacent first interlocking for the target signal of this interlocking, and lock the target protection section corresponding to the first interlocking according to the application lock command. Specifically, the second interlocking can loop through each signal to be configured by itself. If it is the target signal of this interlocking, it will obtain the interlocking to which the first section outside the target signal belongs, the total number of protection sections protected by the target signal, and the protection section. If the interlocking ID to which the target signal belongs is the same as the target interlocking, it will traverse each protection section to determine the target protection section included in this interlocking, and judge whether the target protection section meets the locking conditions. If it is judged that it meets the locking conditions, it means that the target protection section is locked and can pass the inspection, and then jump out of the loop, and send the protection section validity flag to the first interlocking through the target signal, and the protection section validity flag is locked and valid, and notify the first interlocking that the target protection section of the corresponding route of the target signal has been established.

[0135] For example, Figure 5 FIG. 1 is a flowchart of a second interlocking protection zone locking process provided by an embodiment of the present specification, such as Figure 5 As shown, the second interlock periodically traverses each configured signal machine to determine whether the signal machine belongs to this interlock. If it does not belong to this interlock, it will not be processed. If it belongs to this interlock, the application lock command of the signal machine is obtained. The protection direction of the signal machine is obtained, and the protection section protected by the signal machine is obtained to determine whether the application lock command is valid. If invalid, it will not be processed; if valid, it will determine whether the data of the protection section protected by the signal machine is valid. If invalid, an error is returned. If valid, then traverse each protection section associated with the signal to determine whether the protection section belongs to this interlocking. If not, do not process it. If yes, check whether the protection section meets the locking conditions, where the locking conditions include the following checks: check that the physical sections in the target protection section are not locked, check that the physical sections in the protection section are idle, check that the return routes in the target protection section are idle, check that the intrusion section and conditional switches in the target protection section meet the specified position, check that the hostile intrusion section of the target protection section is not locked, check that the switches in the target protection section do not guide the main lock, check that the switches and protective switches in the target protection section are not locked, check that all physical sections in the target protection section are not locked or are normally locked or protectively locked in the same direction as the cross-interlocking route, check that the positions of the switches in the target protection section are correct or the switch positions are incorrect but can be moved, check that the switch positions of the conditional switches in the target protection section are correct, and check that the physical sections in the target protection section are not jump-locked.

[0136] Determine whether all the above checks are passed. If so, lock the protection section for the corresponding cross-interlocking route, and return the protection section validity flag to the adjacent first interlocking through the signal. If not, return an error and exit the loop.

[0137] The embodiments of this specification provide a method for locking a protection section of a cross-interlocking route, which is applied to the second interlocking and can obtain an application locking command of a terminal signal of the cross-interlocking route in the first interlocking. When the application locking command indicates that the target protection section to be locked is a section included in the second interlocking, it is checked whether the target protection section meets the locking conditions. If it meets the locking conditions, the target protection section is locked for the cross-interlocking route, and a protection section validity flag is returned to the first interlocking. The protection section validity flag indicates that the locking of the target protection section is valid, and is used for the first interlocking to update the protection section locking flag of the cross-interlocking route, complete the locking of the protection section of the cross-interlocking route, and establish a protection section for the cross-interlocking route of the first interlocking through the second interlocking, thereby realizing the locking of the protection section for the cross-interlocking route between adjacent interlockings under interconnection and intercommunication, and ensuring that the cross-interlocking route can be handled normally under interconnection and intercommunication.

[0138] Figure 6 An interactive diagram of the processing procedure of a method for locking a protection section across an interlocking route provided by an embodiment of the present specification is shown.

[0139] The first interlocking obtains a terminal signal across the interlocking route, wherein the terminal signal is a signal included in the second interlocking; and the terminal signal is configured in the first interlocking.

[0140] The first interlocking traverses each signal configured therein to determine whether the interlocking to which each signal belongs is on the same line as the first interlocking. If not, the validity flag of the protection section associated with the signal is initialized to lock invalid.

[0141] The first interlocking periodically obtains the locking flag of the protection section across the interlocking route. When the locking flag of the protection section indicates that the lock is not set, traverse the protection sections across the interlocking route, and determine whether each protection section meets the locking establishment conditions based on the physical sections and conditional switches of each protection section; if any protection section meets the locking establishment conditions, the locking flag of the protection section is updated to set as locked.

[0142] The first interlocking, when all protection sections do not meet the locking establishment conditions, traverses each protection section across the interlocking route to determine whether each protection section meets the locking application conditions; if the target protection section meets the locking application conditions, a locking application command for the target protection section is sent to the second interlocking through the terminal signal of the cross-interlocking route.

[0143] The second interlocking traverses each signal configured therein, and when traversing to the terminal signal, obtains the application locking command of the terminal signal.

[0144] The second interlocking obtains the protection direction of the terminal signal and the associated protection sections, determines whether the locking application command of the terminal signal is valid and whether the data of each protection section is valid; if valid, traverses the protection sections associated with the terminal signal, and when traversing to the target protection section indicated by the locking application command, checks whether the target protection section meets the locking conditions. If it meets the locking conditions, locks the target protection section across the interlocking route, updates the protection section validity flag to lock valid, and returns the updated protection section validity flag to the first interlocking through the terminal signal.

[0145] The first interlocking obtains the protection section validity flag returned by the second interlocking according to the terminal signal of the cross-interlocking route; if the protection section validity flag is locked, the protection section locking flag is updated to locked.

[0146] The embodiment of this specification provides a method for locking a protection section across an interlocking route, in which a terminal signal machine for the interlocking route is configured in the first interlocking. When the locking flag of the protection section is that the locking is not set, and the protection sections of the interlocking route do not meet the locking establishment conditions, it means that the cross-interlocking route has not yet established a protection section. At this time, it can be further determined whether the protection sections of the cross-interlocking route meet the locking application conditions. If any protection section meets the locking application conditions, a locking application command for the protection section is sent to the second interlocking through the terminal signal machine of the cross-interlocking route. When the target protection section meets the locking conditions, the second interlocking locks the target protection section for the cross-interlocking approach, and returns the protection section validity flag to the first interlocking. The protection section validity flag indicates that the locking of the target protection section is valid, which is used for the first interlocking to update the protection section locking flag of the cross-interlocking approach, and complete the locking of the protection section of the cross-interlocking approach, so as to establish a protection section for the cross-interlocking approach of the first interlocking through the second interlocking, thereby realizing the locking of the protection section for the cross-interlocking approach between adjacent interlockings under interconnection and intercommunication, and ensuring that the cross-interlocking approach can be handled normally under interconnection and intercommunication.

[0147] Corresponding to the above method embodiment, this specification also provides an embodiment of a protection section locking device applied to a cross-interlocking route of a first interlocking, Figure 7 FIG. 1 shows a schematic diagram of a cross-interlocking protection zone locking device provided by an embodiment of the present specification. Figure 7 As shown, the device comprises:

[0148] A configuration module 702 is configured to obtain a terminal signal machine of a cross-interlocking route, and configure the terminal signal machine in the first interlocking machine, wherein the terminal signal machine is a signal machine included in the second interlocking machine;

[0149] A first acquisition module 704 is configured to periodically acquire a protection section locking flag of a cross-interlocking route, wherein the protection section locking flag is a flag indicating whether the cross-interlocking route has successfully established a protection section;

[0150] The first determination module 706 is configured to determine whether each protection section meets the locking application condition when the locking flag of the protection section is that the locking is not set, and each protection section across the interlocking route does not meet the locking establishment condition, wherein not meeting the locking establishment condition means that each physical section of the protection section is not locked successfully or is locked successfully but the conditional turnout included is not located at the specified position, and the locking application condition is used to check whether each protection section can apply for locking to the second interlocking;

[0151] The sending module 708 is configured to send a locking application command for the target protection section to the second interlocking through the terminal signal configured by itself if the target protection section meets the locking application conditions, wherein the target protection section is any one of the protection sections across the interlocking route, the second interlocking is the adjacent interlocking of the first interlocking, and the locking application command is used to instruct the second interlocking to lock the target protection section across the interlocking route and update the protection section validity flag.

[0152] Optionally, the device further includes a second determining module, configured to:

[0153] If the protection section locking flag is not set to lock, then traverse each protection section, and determine whether each protection section meets the locking establishment conditions according to each physical section and conditional turnout of each protection section;

[0154] If any protection section meets the lock establishment conditions, the protection section lock flag will be updated to lock set.

[0155] Optionally, the second determining module is further configured to:

[0156] Determine whether each physical section is locked successfully according to the locking status of each physical section of the first protection section, wherein the first protection section is any one of the protection sections across the interlocking route;

[0157] If each physical section is locked successfully, determine whether the conditional turnout contained in the first protection section is located at the specified position. If so, determine that the first protection section meets the locking establishment conditions; if not, determine that the first protection section does not meet the locking establishment conditions, and continue to traverse the next protection section across the interlocking route.

[0158] Optionally, the device further includes an updating module configured to:

[0159] According to the terminal signal of the cross-interlocking route, obtain the protection section validity flag returned by the second interlocking;

[0160] If the protection section validity flag is locked, the protection section locking flag is updated to locked.

[0161] Optionally, the device further includes an initialization module configured to:

[0162] Determine whether the interlocking to which the first signal belongs and the first interlocking are on the same line, wherein the first signal is any one of the signals configured for the first interlocking;

[0163] If they are not the same line, the protection section validity flag associated with the first signal will be initialized to lock invalid.

[0164] Optionally, the sending module 708 is further configured to:

[0165] Check whether the last physical section of the cross-interlocking route is free, check whether the last physical section of the cross-interlocking route is locked normally and belongs to the cross-interlocking route, check that all physical sections in the second protection section are not locked, check that all physical sections in the second protection section are free, check that all physical sections in the second protection section are not requisitioned, check that all physical sections in the second protection section are not locked or are normally locked or protectively locked in the same direction as the cross-interlocking route, check that the intrusion section and conditional turnouts in the second protection section meet the specified position, check that the hostile intrusion section of the second protection section is not locked, check that each turnout in the second protection section does not guide the main lock, check that the turnouts and protective turnouts in the second protection section are not locked, and check that each physical section in the second protection section is not jump-locked, wherein the second protection section is any one of the protection sections of the cross-interlocking route;

[0166] If all the above checks are passed, it is determined that the second protection zone meets the lock application conditions;

[0167] If any of the checks fails, it is determined that the second protection section does not meet the lock application conditions, and the next protection section is traversed.

[0168] The embodiments of this specification provide a locking device for a protection section of a cross-interlocking route, which is applied to a first interlocking, and a terminal signal of a cross-interlocking route is configured in the first interlocking. When the locking mark of the protection section indicates that locking is not set, and the protection sections of the cross-interlocking route do not meet the locking establishment conditions, it means that the cross-interlocking route has not yet established a protection section. At this time, it can be further determined whether the protection sections of the cross-interlocking route meet the locking application conditions. If any protection section meets the locking application conditions, a locking application command for the protection section is sent to the second interlocking through the terminal signal of the cross-interlocking route, so as to establish a protection section for the cross-interlocking route through the second interlocking, thereby realizing the locking of the protection section of the cross-interlocking route between adjacent interlockings under interconnection, and ensuring that the cross-interlocking route can be handled normally under interconnection.

Figure 8 As shown, the device comprises:

[0170] The second acquisition module 802 is configured to acquire a locking application command of a target signal, wherein the target signal is a signal included in the second interlocking, and the target signal is a terminal signal of a cross-interlocking route configured in the first interlocking, the locking application command is initiated by the first interlocking through the target signal, and the first interlocking is an adjacent interlocking of the second interlocking;

[0171] The checking module 804 is configured to check whether the target protection section meets the locking condition when the locking command indicates that the target protection section to be locked is a section included in the second interlocking;

[0172] The locking module 806 is configured to lock the target protection section for the cross-interlocking route if the locking conditions are met, update the protection section validity flag to lock valid, and return the updated protection section validity flag to the first interlocking through the target signal, wherein the protection section validity flag is used by the first interlocking to update the protection section locking flag of the cross-interlocking route.

[0173] Optionally, the device further includes a third determining module, configured to:

[0174] Obtain the protection direction of the target signal and each protection zone associated with the target signal;

[0175] According to the protection direction of the target signal and the protection sections associated with the target signal, determine whether the lock application command of the target signal is valid and whether the data of each protection section is valid;

[0176] If valid, then traverse each protection section associated with the target signal to determine whether each protection section is a section included in the second interlocking.

[0177] Optionally, the checking module 804 is further configured to:

[0178] Check that all physical sections within the target protection section are not locked, check that all physical sections within the protection section are free, check that all return routes within the target protection section are free, check that the intrusion section and conditional turnouts within the target protection section meet the specified position, check that the hostile intrusion section of the target protection section is not locked, check that all turnouts within the target protection section are not guided by the main lock, check that the turnouts and protective turnouts within the target protection section are not locked, check that all physical sections within the target protection section are not locked or are normally locked or protectively locked in the same direction as the route across the interlocking route, check that the position of each turnout within the target protection section is correct or the turnout position is incorrect but can be moved, check that the turnout position of each conditional turnout in the target protection section is correct, and check that all physical sections within the target protection section are not jumped and locked;

[0179] If all the above checks are passed, it is determined that the target protection section meets the locking conditions;

[0180] If any of the checks fails, it is determined that the target protection section does not meet the locking conditions.

[0181] The embodiments of this specification provide a protection section locking device for a cross-interlocking route, which is applied to the second interlocking and can obtain the application locking command of the terminal signal of the cross-interlocking route in the first interlocking. When the application locking command indicates that the target protection section to be locked is a section included in the second interlocking, it checks whether the target protection section meets the locking conditions. If it meets the locking conditions, the target protection section is locked for the cross-interlocking route, and a protection section validity flag is returned to the first interlocking. The protection section validity flag indicates that the locking of the target protection section is valid, and is used for the first interlocking to update the protection section locking flag of the cross-interlocking route, complete the locking of the protection section of the cross-interlocking route, and establish a protection section for the cross-interlocking route of the first interlocking through the second interlocking, thereby realizing the locking of the protection section for the cross-interlocking route between adjacent interlockings under interconnection and intercommunication, and ensuring that the cross-interlocking route can be handled normally under interconnection and intercommunication.

[0186] The embodiment of this specification provides a cross-interlocking route protection section locking system, in which a terminal signal of the cross-interlocking route is configured in the first interlocking. When the protection section locking flag is that the lock is not set, and each protection section of the cross-interlocking route does not meet the lock establishment conditions, it means that the cross-interlocking route has not yet established a protection section. At this time, it can be further determined whether each protection section of the cross-interlocking route meets the lock application conditions. If any protection section meets the lock application conditions, the terminal signal of the cross-interlocking route sends a lock application command for the protection section to the second interlocking. When the target protection section meets the locking conditions, the second interlocking locks the target protection section for the cross-interlocking approach, and returns the protection section validity flag to the first interlocking. The protection section validity flag indicates that the locking of the target protection section is valid, which is used for the first interlocking to update the protection section locking flag of the cross-interlocking approach, and complete the locking of the protection section of the cross-interlocking approach, so as to establish a protection section for the cross-interlocking approach of the first interlocking through the second interlocking, thereby realizing the locking of the protection section for the cross-interlocking approach between adjacent interlockings under interconnection and intercommunication, and ensuring that the cross-interlocking approach can be handled normally under interconnection and intercommunication.
