Abstract
Description
Technical Field
[0001] This application belongs to the field of rail transit technology, and in particular relates to a method, system, storage medium and device for protecting the section. Background Technology
[0002] Traditional national railway train control systems typically require sufficient safety clearance between station tracks to ensure trains stop safely and accurately. However, this design results in larger stations and higher construction costs.
[0003] In the practical application of the CTCS2+ATO train control system in urban railways, due to station limitations, the track length of many stations cannot meet the requirements of traditional safety protection distances. If the track length is too short, trains may overshoot signals during operation, leading to serious safety hazards. To solve this problem, existing technologies typically require extending the protection zone of one signal into the protection range of an adjacent signal to achieve safety protection within a limited space. However, this approach places higher demands on the functionality of the station computer interlocking system / train control interlocking integrated system (CBI / TIS), necessitating a technical means that can support the protection zone function to ensure train operation safety and efficiency under short track conditions. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, this application provides a protected section processing method, system, storage medium and device.
[0005] This application is achieved through the following technical solution: Configure the protected segment state machine in the CBI / TIS system; Set the approach status and corresponding exit conditions of the state machine of the protected area section, configure the protected area section data, and supplement the change configuration instructions based on the existing approach interlock table; The system acquires real-time train information and uses the protected section state machine to check the corresponding turnout conditions based on the route status and the real-time train information to generate valid protected section information. The effective information of the protected area is sent to TCC / TSRS in real time.
[0006] Optional, The route states of the state machine in the protected area include: route selection, route verification, pre-locking, lockout holding, and complete unlocking; The route status is triggered by whether the corresponding exit condition is met.
[0007] Optional, The turning conditions for the route selection include: The protected area was not blocked by hostile routes; All sections within the protected area (including sections exceeding the limit) are in a vacant state; All switches within the protected section were not locked in unexpected positions; All switches within the protected area were not blocked; The protected area meets the conditions for inspection; If the turning conditions for the route selection are met, then turn to the route check; otherwise, turn to full unlock.
[0008] Optional, The outbound conditions for route verification include: The protected area was not blocked by hostile routes; All sections within the protected area (including sections exceeding the limit) are in a vacant state; All switches within the protected section were not locked in unexpected positions; All switches within the protected area were not blocked; The protected area meets the conditions for inspection; If the exit conditions of the route check are met and the following conditions are also met: the position of the turnout does not meet the route requirements and the turnout switching delay has not ended, then the route check is maintained. If the turning-out conditions of the route check are met and the turnout position meets the route requirements, then turn out to the pre-locked position.

[0010] Optional, The lock-holding release conditions include: Once the train has fully entered the stopping zone, and the stopping delay period receives information that the train has come to a complete stop, if the protected zone is clear and the switch position is correct, then the protected zone is unlocked; if the protected zone is not clear or the switch position is incorrect during the stopping delay period, then the stopping delay is stopped and the protected zone is not unlocked. Once the train has fully entered the stopping section, and the stopping delay has ended, if the protected section is free and the switches are in the correct position, then the protected section is unlocked; if the protected section is not free or the switches are in the wrong position during the stopping delay, then the stopping delay is stopped and the protected section is not unlocked. When the protected section is repeatedly locked by a subsequent route, the protected section will automatically unlock as the train route unlocks and the first section of the subsequent train route unlocks. After the train route is cancelled or manually unlocked, the protected section is free and the switch position is correct.

If any of the above-described lock-holding exit conditions are not met, then the lock-holding remains in place.
[0023] S4. Send the effective information of the protected area to TCC / TSRS in real time.
[0024] Based on real-time train information, the corresponding protection section is locked / unlocked, and the transition status of the protection section state machine is used as valid information of the protection section and sent to TCC / TSRS in real time. The real-time train information includes station status information and train stopping and accurate information received from TCC / TSRS; the effective information of the protected section is the state that the protected section is locked and empty, and the turnout position is correct and meets the inspection conditions.
[0025] The protected section processing method of this application embodiment is based on the existing route management function logic of the CBI / TIS system, and adds a protected section function module to realize the functions of locking protected sections for different paths and unlocking various types of protected sections, and sends the protected section locking information to TCC / TSRS in real time.
[0026] I. Status Machine of Protected Section In the CBI / TIS system, a protected segment state machine is set up as a protected segment functional module.
[0027] In this embodiment, the CBI / TIS system is used to implement the basic functions such as existing route management and data support.
[0028] The state machine for the protected area section is used to perform dynamic protection logic judgments, including: Based on the route status and real-time data detection, the corresponding exit conditions for each status are triggered, status transitions are generated, and valid information for the protected section is generated.
[0029] II. State Machine and Data Settings for Protected Areas The approach status and corresponding exit conditions of the protected section state machine are set, the protected section data is configured, and the configuration changes are supplemented based on the existing approach interlock table. This is used to extend a part of the protection area of one signal to the range of the protection area of the next signal.
[0030] 1. Set up a state machine for the protected section.
[0031] The CBI / TIS train route status includes 12 states: Train Turnout Processing (LCXCCL), Train Route Verification (LCJLJH), Train Pre-locking (LCYXSB), Train Signal Open (LCXHKF), Train Approach Locking (LCJJSB), Train Signal Closed (LCXHGB), Train Signal Fault Closed (LCXHZB), Train Normal Unlocking (LCZCJS), Train Manual Unlocking (LCRGJS), Train Route Cancellation (LCQXJL), Train Gradient Unlocking (LCPDJS), and Train Fully Unlocked (LCWQJS). The route status triggers a state transition based on whether the corresponding departure conditions are met, and each status has different corresponding processing logic.
[0032] In this embodiment, the protected section state machine is used as a protected section functional module to realize the protected section function in CBI / TIS, that is, a section extending from the protected area of one signal to the protected area of the next signal. The protected section state machine has five route states: route selection (LCXCCL), route verification (LCJLJH), pre-locked (LCYXSB), locked and held (BHSBBC), and fully unlocked (LCWQJS).
[0033] The state machine processing of the protected section includes: protected section registration, protected section turn selection, protected section verification, protection pre-locking, protection lock maintenance, and protected section unlocking.
[0034] The corresponding relationships between the approach status, exit conditions, and exit status in the state machine processing of the protected section are shown in Table 1.
[0035] Table 1
[0036] 2. Data configuration for protected areas.
[0037] To enable the protection section function of extending a section of a signal's protection zone into the protection zone of the next signal, the protection section configuration can be reused from subsequent route sections and turnout configurations by supplementing the configuration description based on the existing route interlocking table.
[0038] In this embodiment, two new variables, the number of turnouts and the number of protected sections, are added to the existing route interlocking table, along with supplementary configuration change instructions. By configuring the protected section data, based on the existing basic train route functions and configuration methods in CBI / TIS, it is possible to use designated sections and turnout configurations of subsequent routes as protected sections of the basic route. The protected section state machine performs logical operations and periodically checks state transition conditions based on the configured number of sections, thereby realizing the locking and unlocking management of protected sections and turnouts.
[0039] As shown in Table 2, supplementary configuration changes are provided based on the existing route interlocking table:
[0040] III. Treatment of Protected Sections The system acquires real-time train information and uses the protected section state machine to check the corresponding turnout conditions based on the route status and the real-time train information, thereby generating valid protected section information.
[0041] The real-time train information includes: station status information and train stopping and accurate information received from TCC / TSRS; the effective information of the protected section is the status of the protected section being locked and free, and the turnout position being correct and meeting the inspection conditions.
[0042] In this embodiment, the real-time train information includes station status information and train stopping and accurate information received from TCC / TSRS; the transition status of the protection section state machine is the valid information of the protection section.
[0043] 1. Triggering and locking of protected sections.
[0044] (1) Protection section registration: There may be one or more protection section schemes for the train route. In addition to sharing the starting signal train button, each protection section scheme also needs to be equipped with a protection terminal button for protection section registration (registration method: press the starting signal train button and the protection section terminal button in sequence).
[0045] (2) When the protected section path of the train route is unique, the protected section is automatically set as the train route is established; when the protected section path is not unique, the protected section is set according to the operation command (including CTC command). When the setable protected section path is not unique, but there is a unique protected section path that completely overlaps with the subsequent forward train route and the subsequent train route status is turnout processing, route verification, pre-locking, signal open, or approaching locking, the overlapping protected section is automatically set as the train route is established.
[0046] (3) After the corresponding train route in the protected section is established and locked, the protected section can be automatically or manually triggered and enter the protected section turnout state. At this stage, it is necessary to check whether the turning conditions of the protected section turnout process (in the route turnout state) are met: The protected area was not blocked by hostile routes; All sections within the protected area (including sections exceeding the limit) are in a vacant state; All switches within the protected section were not locked in unexpected positions; All switches within the protected area were not blocked; The protected area meets the requirements for inspection.
[0047] If the conditions for turning out of the protection zone are met, a turnout operation command is output, and the protection zone turns out from the route selection state to the route verification state; if the conditions are not met, it turns out to the fully unlocked state.
[0048] (4) During the specified turnout turning time, the protected section continuously outputs turnout operation commands. During this stage, it is necessary to check whether the turnout conditions of the route verification are met: The protected area was not blocked by hostile routes; All sections within the protected area (including sections exceeding the limit) are in a vacant state; All switches within the protected section were not locked in unexpected positions; All switches within the protected area were not blocked; The protected area meets the requirements for inspection.
[0049] If the exit conditions for route verification are met and the following conditions are also met: the position of the unpassed turnout meets the route requirements and the turnout switching delay has not ended, then the route verification status is maintained. If the turnout conditions for route verification are met and the turnout position meets the route requirements, then turnout to the pre-locked state. If the turnout conditions for route verification are not met, or the turnout position does not meet the route requirements and the turnout conversion delay ends, the system will switch to a fully unlocked state.
[0050] (5) Within a specified time, the protection section will automatically operate the corresponding turnout to the corresponding position according to the turnout operation command. When all the turnouts are in the expected position, the protection section and the turnouts within the protection section will be locked.
[0051] In the pre-locked state, the protected section state machine checks whether the pre-locked exit conditions are met: The switch location meets the route requirements; The protected area was not blocked by hostile routes; All sections within the protected area (including sections exceeding the limit) are in a vacant state; All switches within the protected area were not blocked; The protected area meets the requirements for inspection.
[0052] If the pre-locked exit conditions are met, all sections and switches in the protected area will be locked and switched to the locked holding state. If the pre-locked exit conditions are not met or the protected area is not properly locked, the system will switch to a fully unlocked state.
[0053] (6) After the protected area is locked, the protected area state machine enters the lock-up holding phase, during which the following processes should be continuously performed: a. Continuously drive the site's monitoring and tracking; b. Continuously check that the protected section (including the over-limit section) is clear and that the turnout position is correct and meets the inspection conditions. If the conditions are met, the corresponding train route is opened (when it is opened for the first time). If the conditions are not met, the signal is blocked. c. Continuously handle train routes, guiding routes, and shunting routes that overlap with the opposite direction, and handle shunting routes that overlap with the forward direction.
[0054] d. Continuously check the unlocking conditions of the protected area. If the unlocking conditions are met, proceed to the fully unlocked protected area phase.
[0055] e. Continuously connect the protected section with the train route: If a protected section already exists and multiple train routes can be connected, it is necessary to perform splicing processing with the protected routes based on the train route terminal signal, departure section, and route end section information to achieve the splicing and extension of the train route protection range to the protected section. The extended protected section must meet the following requirements: the protected section (including over-limit sections) must be clear, the turnout position must be correct, and the inspection conditions must be met before the starting signal of the train route connecting the protected section can be opened.
[0056] f. Continuously link the protected section with subsequent routes: After the protected section is locked, multiple subsequent train routes can be locked repeatedly, allowing subsequent routes to proceed. However, the protected route must be in opposition to non-subsequent routes, and the protected route will automatically unlock upon the normal unlocking of the first section of the subsequent route. It is necessary to link the protected section with the starting signal, approach section, and first section information of the subsequent route to achieve the opposition function for non-subsequent routes, and the functions of repeated locking and automatic unlocking of subsequent routes.
[0057] 2. Protected area unlocked.
[0058] When the route is in a locked-hold state, the protected section state machine checks the lockout condition (i.e., unlocking condition): Once the train has fully entered the stopping zone, and the stopping delay period receives information that the train has come to a complete stop, if the protected zone is clear and the switch position is correct, then the protected zone is unlocked; if the protected zone is not clear or the switch position is incorrect during the stopping delay period, then the stopping delay is stopped and the protected zone is not unlocked. Once the train has fully entered the stopping section, and the stopping delay has ended, if the protected section is free and the switches are in the correct position, then the protected section is unlocked; if the protected section is not free or the switches are in the wrong position during the stopping delay, then the stopping delay is stopped and the protected section is not unlocked. When a protected section is repeatedly locked by a subsequent route, the protected section should automatically unlock as the train on the first section of the subsequent route unlocks after the train route is unlocked. After the train route is cancelled or manually unlocked, the protected section is free and the switch position is correct. The protected section will automatically unlock as the train route is unlocked. If the train route is in a signal-closed state, the protected section is free and the switch position is correct, the protected section can be unlocked for a delay by using a protection unlocking operation command (including CTC command); if the protected section is not free or the switch position is incorrect during the protection unlocking delay, the unlocking delay will be stopped and the protected section will not be unlocked. If any of the above unlocking conditions are not met, the locked state will remain.
[0059] In this embodiment, after the train has fully entered the stopping section, when the train stops and is ready during the stopping delay period, the protection section is automatically unlocked after checking that the protection section is free, the turnout position is correct, and the corresponding train route has been unlocked. If the check conditions are not met, the stopping delay is stopped and the protection section is not unlocked.
[0060] After the train has fully entered the stationary section, when the unlocking delay of the protected section ends, the protected section will be automatically unlocked after the conditions that the protected section is free, the switch position is correct, and the corresponding train route has been unlocked are met; if the conditions are not met, the stationary delay will be stopped and the unlocking of the protected section will be stopped.
[0061] When the train route corresponding to the protected section is cancelled or manually unlocked, the protected section will be automatically unlocked after the conditions of the protected section being free, the switch position being correct, and the corresponding train route being unlocked are met; if the conditions are not met, the unlocking of the protected section will be stopped.
[0062] If the train route is in a signal-closed state, the protected section is free and the switch position is correct, the protected section can be unlocked for a delay by using a protection unlocking operation command (including CTC command); if the protected section is not free or the switch position is incorrect during the protection unlocking delay, the unlocking delay will be stopped and the protected section will not be unlocked.
[0063] 4. Send the effective information of the protected area to TCC / TSRS in real time.
[0064] Based on real-time train information, the corresponding protection section is locked / unlocked. The transition status of the protection section state machine is sent to the TCC / TSRS in real time as valid protection section information.
[0065] See appendix Figure 2 The structure of a protected section treatment system for implementing the above method is shown, including a CBI / TIS system, a protected section module, and a TCC / TSRS.
[0066] In the CBI / TIS system, a protected section state machine is set as a protected section module. The route status and corresponding turn-out conditions of the protected section state machine are set, and the protected section data is configured. Based on the existing route interlocking table, the change configuration instructions are supplemented. The protected section state machine checks the corresponding turn-out conditions according to the route status and generates valid protected section information. The valid protected section information is sent to TCC / TSRS in real time.
[0067] Based on the same concept, this application also provides a computer-readable storage medium storing one or more programs, which, when executed, can implement the aforementioned protected area processing method.
[0068] like Figure 3As shown in the illustration, this application also provides a device including a processor, a communication interface, a memory, and a communication bus. The processor, communication interface, and memory communicate with each other via the communication bus.
[0069] The memory is a computer-readable storage medium used to store one or more programs.
[0070] The processor is configured to execute a program stored in a computer-readable storage medium.
[0071] The computer-readable storage medium may be included in the device / apparatus described in the above embodiments; or it may exist independently and not assembled into the device / apparatus.
[0072] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
