Description

Technical Field

[0001] The present invention belongs to the field of rail transportation, and in particular relates to a method and system for determining the approach locking of a computer interlocking train route. Background Art

[0002] With the expansion of my country's high-speed railway construction and operation scale and the continuous increase in passenger flow, further improving the train speed and line capacity is an inevitable trend in the development of high-speed railways. However, increasing the train speed means that the braking distance of the train will also increase, and the approach locking length of the station computer interlocking control will also increase.

[0003] At present, the fastest operating speed of existing high-speed railway lines in China is 350km / h (kilometers per hour), and the shortest length of the approach approach locking is about 14.4km (kilometers), corresponding to about 7 block sections. The approach locking point of the route is usually in the interval block section. If the train speed reaches 400km / h, the shortest length of the approach approach locking is about 18km, corresponding to about 10 block sections. If the train speed reaches 450km / h, the shortest length of the approach approach locking is about 26km, corresponding to about 14 block sections. Therefore, for train lines with short station spacing, the train approach locking point of this station may be in the adjacent interval section, the station section of the adjacent station, or the station section of a more distant station. Furthermore, in the current engineering applications of railway lines, the length of the train approach section involved is relatively short, and the train approach locking judgment can be achieved by judging the status of the section block partition or the adjacent JGJ relay. However, when the length of the train approach section is longer, there is still a lack of corresponding train approach locking judgment method. Summary of the Invention

[0004] In response to the above problems, the present invention provides a method and system for determining the approach locking of a computer interlocking train route, which can effectively determine the approach locking of a high-speed train route with the approach locking section located in a distant section or interlocking station.

[0005] The object of the present invention is to provide a method for determining if a train route is approaching locking in a computer interlocking system, comprising:

[0006] Based on the position of the train approaching the locked section, the following judgment scenario is established:

[0007] First judgment scenario: The approaching locking section of the train route is included in the jurisdiction of the adjacent section of the station, the jurisdiction of the interlocking of the station, or the jurisdiction of the adjacent interlocking of the station;

[0008] Second judgment scenario: The approach locking section of the train route is within the jurisdiction of the adjacent station interlocking;

[0009] The third judgment scenario: the approaching locking section of the train route is within the jurisdiction of the adjacent section of the station behind the train route;

[0010] Fourth judgment scenario: The approach locking section of the train route is within the jurisdiction of the rear station interlocking of the adjacent station;

[0011] Obtain a first train route with an open signal, determine all approaching locked sections of the first train route and the determination scenarios where all approaching locked sections are located;

[0012] Starting with the first judgment scenario, the first train route is judged in the corresponding judgment scenarios in the order from near to far of the approach locking section whether it meets the approach locking condition. Among them, when the first train route meets the approach locking condition in any corresponding judgment scenario or the first train route does not meet the approach locking condition in all judgment scenarios corresponding to the approach locking section, the judgment is ended and the judgment result is obtained.

[0013] Furthermore,

[0014] In a station interlocking system, the following sub-scenarios are constructed based on the position of the train approaching the locking section in the station interlocking system:

[0015] First sub-scenario: The approach locking section of the train route is located between the first entry signal and the first exit signal in the station;

[0016] Second sub-scenario: The approach locking section of the train route is located on the track within the station;

[0017] The third sub-scenario: The approach locking section of the train route is located between the second entry signal and the second exit signal in the station;

[0018] When judging whether the first train route meets the approach locking condition in the second judgment scenario and the fourth judgment scenario, starting with the first sub-scenario, judge whether the first train route meets the approach locking condition in the corresponding sub-scenario in the order from near to far of the approach locking section in the station interlocking. When the first train route meets the approach locking condition in any corresponding sub-scenario or the first train route does not meet the approach locking condition in all sub-scenarios corresponding to the approach locking section, the judgment is ended and the judgment result is obtained.

[0019] Further, starting from the first determination scenario, judging whether the first train route meets the approach locking condition in the corresponding determination scenarios in the order of approaching the locking section from near to far includes judging whether the first train route meets the approach locking condition in the first determination scenario, specifically comprising the following steps:

[0020] Step S11: Obtain the block partition status of the adjacent section of the station and / or the JGJ relay status in the adjacent interlocking;

[0021] Step S12: Determine whether the approach section of the first train route is occupied. If so, execute step S16; otherwise, execute step S13.

[0022] Step S13: Determine whether the area behind the first train approach signal is a section or adjacent interlocking; if so, execute step S131; otherwise, execute step S14;

[0023] Step S131: Determine whether the block section state near the locked section in the section is occupied or whether the JGJ relay in the adjacent interlocking is down. If the block section state near the locked section in the section is occupied or the JGJ relay is down, execute step S16; otherwise, execute step S17.

[0024] Step S14: Determine whether the rear approach signal of the first train approach is not open. If it is not open, execute step S141; otherwise, execute step S15;

[0026] Step S142: Determine whether the train enters the rear approach. If so, execute step S16; otherwise, execute step S143.

[0027] Step S143: Determine whether the section in the rear access route is occupied by a fault. If so, execute step S16; otherwise, execute step S17.

[0028] Step S144: determine whether the route behind the signal is a guided route. If so, execute step S145; otherwise, execute step S17;

[0029] Step S145: Determine whether there is any occupied section in the guided route. If yes, execute step S16; otherwise, execute step S17.

[0030] Step S15: Determine whether the block state of the section close to the locked section in the section is occupied or whether the JGJ relay is dropped. If so, execute step S16; otherwise, execute step S17;

[0031] Step S16: The first train route meets the approach locking condition;

[0032] Step S17: The first train route does not meet the approach locking condition.

[0033] Furthermore, starting with the first determination scenario, determining whether the first train route meets the approach locking condition in the corresponding determination scenarios in the order of approaching the locking section from near to far includes determining whether the first train route meets the approach locking condition in the second determination scenario, specifically comprising the following steps:

[0034] Step S20: Determine whether the route signal of the first train route is behind a section or whether the route signal of the route behind the first train route is open. If the route signal of the section or the route signal of the route behind the first train route is open, execute step S21; otherwise, execute step S25.

[0035] Step S21: Determine whether the approaching locking section of the first train route is in the first sub-scenario, the second sub-scenario, or the third sub-scenario. If so, execute step S211; otherwise, execute step S22.

[0036] Step S211: determine whether the train exit route is a train route. If so, execute step S212; otherwise, execute step S214.

[0037] Step S212: Determine whether the train has entered the train route after the route signal is released. If so, execute step S24; otherwise, execute step S213.

[0038] Step S213: After the route signal is released, determine whether the section within the train route is occupied by a fault. If so, execute step S24; otherwise, execute step S214;

[0039] Step S214: Determine whether the outbound route is a guided route. If so, execute step S215; otherwise, execute step S22.

[0040] Step S215: Determine whether the guide route signal is off and whether there is any occupied section in the guide route. If the guide route signal is off and there is any occupied section in the guide route, execute step S24; otherwise, execute step S22.

[0041] Step S22: Determine whether the approaching locking section of the first train route is in the second sub-scenario or the third sub-scenario, wherein if yes, execute step S221; otherwise, execute step S23;

[0042] Step S221: Determine whether the outbound route signal is open. If so, execute step S222; otherwise, execute step S23.

[0043] Step S222: Determine whether there is a vehicle occupying the track. If so, execute step S24; otherwise, execute step S23.

[0044] Step S23: Determine whether the approach locking section of the first train route is in the third sub-scenario. If so, execute step S231; otherwise, execute step S25.

[0045] Step S231: Determine whether all combined route signals are open. If so, execute step S232; otherwise, execute step S25.

[0046] Step S232: Determine whether the train has entered the front route. If so, execute step S24; otherwise, execute step S233.

[0047] Step S233: Determine whether any section in the preceding route is occupied. If so, proceed to step S24; if not, proceed to step S25.

[0048] Step S24: The first train route meets the approach locking condition, and step S26 is executed;

[0049] Step S25: The first train route does not meet the approach locking condition, and step S26 is executed;

[0050] Step S26: The adjacent station interlocking system sends the judgment result to the local station interlocking system.

[0051] Furthermore, starting with the first determination scenario, determining whether the first train route meets the approach locking condition in the corresponding determination scenarios in the order of approaching the locking section from near to far includes determining whether the first train route meets the approach locking condition in the third determination scenario, specifically comprising the following steps:

[0052] Step S31: Determine whether the route signal of the first train route is behind a section or whether the route signal of the route behind the first train route is open. If the route signal of the section or the route signal of the route behind the first train route is open, execute step S32; otherwise, execute step S36;

[0053] Step S32: interlocking with adjacent stations in the section where the block section is located under the third determination scenario to obtain the block partition status of the section where the block section is located under the third determination scenario;

[0054] Step S33: Determine whether the approach locking section of the first train route is occupied. If so, execute step S34; otherwise, execute step S36.

[0055] Step S34: Determine whether there is a combined through route in the adjacent station of the section close to the locked section in the third determination scenario and whether the route signal of the combined through route is open. If there is a combined through route and the route signal is open, execute step S35; otherwise, execute step S36.

[0056] Step S35: If the first train route satisfies the approach locking condition, the judgment result is transmitted to the station interlocking through one or more station interlocking systems step by step. Each time the train passes through a station, the corresponding station interlocking system determines whether there is a combined through route in the station and whether the route signal of the combined through route is open. If there is a combined through route and the route signal is open, the first train route satisfies the approach locking condition in the corresponding station interlocking system. If the first train route satisfies the approach locking condition in all the station interlocking systems that transmit the judgment result step by step, the judgment result is finally transmitted to the station interlocking system. Otherwise, step S36 is executed.

[0057] Step S36: The first train route does not meet the approach locking condition, and the judgment result is sent to the station interlocking step by step through one or more station interlockings.

[0058] Furthermore, starting with the first determination scenario, determining whether the first train route meets the approach locking condition in the corresponding determination scenarios in the order of approaching the locking section from near to far includes determining whether the first train route meets the approach locking condition in the fourth determination scenario, specifically comprising the following steps:

[0059] Step S41: Determine whether the route signal of the first train route is behind a section or whether the route signal of the route behind the first train route is open. If the route signal of the section or the route signal of the route behind the first train route is open, execute step S42; otherwise, execute step S44.

[0060] Step S42: Determine whether the first train route satisfies the approach locking condition at the station where the approach locking section of the first train route is located. If so, execute step S43; otherwise, execute step S44.

[0061] Step S43: The determination result of whether the first train route meets the approach locking condition is transmitted to the station interlocking through one or more station interlockings step by step. Each time the train passes through a station, the corresponding station interlocking determines whether there is a combined through route in the station and whether the route signal of the combined through route is open. If there is a combined through route and the route signal is open, the first train route meets the approach locking condition in the corresponding station interlocking. If the first train route meets the approach locking condition in all the station interlockings to which the determination result is transmitted step by step, the determination result is finally transmitted to the station interlocking. Otherwise, step S44 is executed.

[0062] Step S44: The first train route does not meet the approach locking condition, and the judgment result is sent to the station interlocking step by step through one or more station interlockings.

[0063] Furthermore, any station interlocking system communicates with the corresponding adjacent station interlocking system, any station interlocking system communicates with the corresponding adjacent section, and any station interlocking system communicates with the corresponding adjacent interlocking system via Ethernet or relay interfaces.

[0071] The judgment module is used to start with the first judgment scenario and judge whether the first train route meets the proximity locking condition in the corresponding judgment scenarios in the order from near to far of the proximity locking section.

[0075] Second sub-scenario: The approach locking section of the train route is located on the track within the station;

[0104] Step S231: Determine whether all combined route signals are open. If so, execute step S232; otherwise, execute step S25.

[0105] Step S232: Determine whether the train has entered the front route. If so, execute step S24; otherwise, execute step S233.

[0106] Step S233: Determine whether any section in the preceding route is occupied. If so, proceed to step S24; if not, proceed to step S25.

If the route signal of the section or the route signal of the route behind the first train route is open, execute step S32; otherwise, execute step S36;

[0112] Step S32: interlocking with adjacent stations in the section where the block section is located under the third determination scenario to obtain the block partition status of the section where the block section is located under the third determination scenario;

[0115] Step S35: If the first train route satisfies the approach locking condition, the judgment result is transmitted to the station interlocking through one or more station interlocking systems step by step.

[0134] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0135] like Figure 1As shown, an embodiment of the present invention discloses a method for determining if a computer interlocking train route is approaching locking. The method includes, first, building the following determination scenarios based on the position of the train route approaching locking section: the first determination scenario: the approaching locking section of the train route is included in the jurisdiction of the adjacent section of the station, the jurisdiction of the interlocking of the station, or the jurisdiction of the adjacent interlocking of the station; the second determination scenario: the approaching locking section of the train route is within the jurisdiction of the interlocking of the adjacent station; the third determination scenario: the approaching locking section of the train route is within the jurisdiction of the adjacent section of the station behind the train route; the fourth determination scenario: the train route The approach locking section is within the jurisdiction of the rear station interlocking of the adjacent station; then, the first train route with the open signal is obtained, and all the approach locking sections of the first train route and the judgment scenarios where all the approach locking sections are located are determined; starting with the first judgment scenario, the first train route is judged in the corresponding judgment scenarios in the order of approach locking sections from near to far whether it meets the approach locking conditions, wherein, when the first train route meets the approach locking conditions in any corresponding judgment scenario or the first train route does not meet the approach locking conditions in the judgment scenarios corresponding to all approach locking sections, the judgment is ended and the judgment result is obtained. For various scenarios of the train route approach locking section positions, the train route approach locking conditions are judged, and under the premise of ensuring safety and operational efficiency, the effective judgment of the high-speed train route approach locking conditions with the approach locking section located in a relatively distant section or interlocking station is achieved.

[0136] like Figure 2 As shown, the first to fourth determination scenarios are replaced by scenarios 1 to 4, and the train route approach locking determination method includes checking the approach locking conditions of the train route in scenario 1 by default. If the approach locking conditions of the train route are not met in scenario 1, then according to the applicable scenario of the approach locking section of the train route, check whether the approach locking conditions of the train route are met in scenario 2, scenario 3 or scenario 4. If any inspection result in all the scenarios applicable to the route is that the approach locking conditions are met or the approach locking conditions are not met in all scenarios, then stop the judgment to obtain the judgment result. Furthermore, if the train route meets the approach locking conditions in a certain scenario, the locked state of the train route is changed to the approach locking state, otherwise the locked state of the train route remains unchanged. Figure 4For example, if the approach locking section of a train route is located in CBI-3, then the train route and the approach locking section in CBI-3 also include the approach locking section located in CBI-1 (belonging to scenario 1), the approach locking section located in CBI-2 (belonging to scenario 2), and the approach locking section located in the adjacent section TCC-2 of CBI-2 (belonging to scenario 3). Therefore, when judging the approach locking condition of the train route, it is defaulted to first judge whether the train route meets the approach locking condition under scenario 1. If scenario 1 does not meet the condition, then judge whether the train route meets the approach locking condition under scenario 2. If scenario 2 does not meet the condition, continue to judge under scenario 3. If scenario 3 does not meet the condition, then judge under scenario 4. Furthermore, if a section with a short station spacing or a station with a short station yard distance is involved, there may be a scenario where the approach locking section is governed by a more distant interlocking or section. For example, if the approach locking section of the train route is in an adjacent station behind CBI-3, the scenarios involved include scenario 1, scenario 2, scenario 3, scenario 4, scenario 3 (the approach locking section within the jurisdiction of the adjacent section TCC-3), and scenario 4 (the approach locking section within the jurisdiction of the station interlocking of the adjacent station behind CBI-3). Then, in the order of the approach locking sections from near to far (i.e., the order described above), the first train route is judged in the corresponding judgment scenario to determine whether it meets the approach locking condition. Preferably, it is also possible to determine whether the first train route meets the approach locking condition in the corresponding judgment scenario at the same time. If any of the inspection results of all the scenarios applicable to the route show that the approach locking condition is met, the locking state of the route is changed to the approach locking state; otherwise, the original locking state is maintained. Scenarios 1 to 4 are constructed from near to far based on the distance between the approach locking section and the train route. This effectively considers the location of each approach locking section and further checks whether the train route meets the approach locking conditions in each judgment scenario involved, ensuring the safe and stable operation of the train. It should be further explained that the approach locking section refers to the approach locking section length calculated based on the operating speed permission of the line. The area within this length behind the first train route signal can be called the approach locking section.

[0137] The first judgment scenario is the application scenario where the approach locking section of the train route is included in the jurisdiction of the adjacent section, or the jurisdiction of the station interlocking, or the jurisdiction of the adjacent interlocking, such as Figure 3 As shown, in the first judgment scenario, determining whether the first train route meets the approach locking condition includes the following steps:

[0138] Step S11, obtain the block section status of the adjacent section of the station and / or the JGJ relay status in the adjacent interlocking of the station; the station is the station where the first train route is located.

[0139] Step S12: Determine whether the approach section of the first train route is occupied. If so, execute step S16; otherwise, execute step S13.

[0140] Step S13: Determine whether the route signal of the first train route is followed by a section or adjacent interlocking. If so, execute step S131; otherwise, execute step S14.

[0141] Step S131, determine whether the block section status of the locking section in the interval close to the locking section is occupied or whether the JGJ relay in the adjacent interlocking is down. If the block section status of the locking section in the interval close to the locking section is occupied or the JGJ relay in the adjacent interlocking is down, execute step S16, otherwise, execute step S17; that is, if the route signal of the first train route is behind the interval, determine whether the block section status of the locking section in the interval close to the locking section is occupied. If it is occupied, execute step S16, otherwise execute step S17; if the route signal of the first train route is behind the adjacent interlocking, determine whether the JGJ relay in the adjacent interlocking is down. If the JGJ relay in the adjacent interlocking is down, execute step S16, otherwise, execute step S17.

[0142] Step S14: Determine whether the rear approach signal for the first train route (i.e., the approach signal for the rear approach) is closed. If so, proceed to step S141; otherwise, proceed to step S15. Specifically, routes with closed rear approach signals in this step include routes that may have been approved for approach but have not yet been approved for approach. Routes with approved rear approach signals include routes that have already been approved for approach and have had their signals approved. Furthermore, all of the aforementioned rear approaches are still within the station.

[0143] Step S141: Determine whether the rear route behind the signal (i.e., the route behind the rear route signal) is a train route. If so, execute step S142; otherwise, execute step S144.

[0144] Step S142: Determine whether the train enters the rear approach. If so, execute step S16; otherwise, execute step S143.

[0145] Step S143: Determine whether the section in the rear access route is occupied by a fault. If so, execute step S16; otherwise, execute step S17.

[0146] Step S144: determine whether the route behind the route signal of the first train route is a guiding route. If so, execute step S145; otherwise, execute step S17;

[0147] Step S145: Determine whether there is any occupied section in the guided route. If yes, execute step S16; otherwise, execute step S17.

[0148] Step S15: Determine whether the approach locking section in the rear approach section is occupied or whether the JGJ relay is down. If the approach locking section is occupied or the JGJ relay in the approach locking section is down, execute step S16; otherwise, execute step S17;

[0149] Step S16: The first train route meets the approach locking condition;

[0150] Step S17: The first train route does not meet the approach locking condition.

[0151] In Scenario 1, the positions close to the locked section are checked gradually from near to far, realizing the protection of the high-speed train route from near to far, and ensuring the safety of the train.

[0152] For example, Figure 4 As shown, CBI-1, CBI-2, and CBI-3 are all station interlockings (also called interlocking stations), TCC-1 is the adjacent section of CBI-1, TCC-2 is the adjacent section of CBI-2, and CBI-N is the adjacent interlocking of CBI-1. CBI-1 and TCC-1 can communicate via Ethernet, and information is transmitted between CBI-1 and CBI-N through relay status. CBI-1 and CBI-2, and CBI-2 and CBI-3 can all communicate via Ethernet. It should be noted that: for sections with short station spacing or stations with short station yard distances, there may be approach locking sections that are governed by more distant interlocking or sections, and the approach locking conditions are transmitted back to this station step by step through Ethernet communication and / or relay interface.

[0153] In the embodiment of the present invention, the determination of whether the first train route meets the approach locking condition in the first determination scenario is described by taking the CBI-1 station scenario as an example.

[0154] When the first train route is the train route (SI->X), and the approach locking section of the train route (SI->X) is included in the jurisdiction of the station interlocking, the train route (SI->X) meets the approach locking conditions when:

[0155] 1) The signal of the train approach route (SI->X) is open and the approach section (IG) is occupied.

[0156] 2) The signal for the rear approach of the train route (SI->X) is open, the rear approach is a train route, and the train is operating within the rear approach. Specifically, when the train is in operation, the train will pass through the combined through route (SF->IG->X). The SF entry signal and the X exit signal of the combined through route (SF->IG->X) are both open. At this time, the train route (SI->X) is within the combined through route (SF->IG->X). That is, the train route (SI->X) has a rear approach, the SF entry signal in the rear approach is open, and the train normally enters the inside of the SF entry signal (i.e., enters the rear approach). The route (SI->X) is determined to meet the approach locking conditions. When the train is not operating, the combined through route (SF->IG->X) is fully locked, SI is open, and any section within the preceding approach is occupied. The approach (SI->X) is determined to meet the approach locking conditions. The preceding approach refers to the route between SF and SI. Non-train operation refers to the interlocking inspection that there is an occupation process in the section within the route, which specifically includes the sudden occupation of the section within the route without an approaching train, or the occupation of the section within the route is not in the order of occupying from far to near, and there are cases of missed occupancy or skipped occupancy.

[0157] 3) The signal of the rear route of the train route (SI->X) is open, the rear route is a train route, and the rear route is occupied by a fault.

[0158] 4) The signal of the rear route of the train route (SI->X) is open, the rear route is the leading route, and there is a section occupied in the leading route.

[0159] When the first train route is the receiving route (SF->XI), and the approach-locking section of the receiving route (SF->XI) is within the adjacent section or is included in the jurisdiction of TCC-1, the receiving route (SF->XI) meets the approach-locking conditions when:

[0160] 1) After the station entry signal is opened, the section behind the train approach route (SF->XI) is the section, and the train enters the approach locking section within the section under the jurisdiction of TCC-1.

[0161] When the first train route is the departure route (SI->X), and the approach-locking section of the departure route (SI->X) is within the adjacent section or is within the jurisdiction of TCC-1, the departure route (SI->X) meets the approach-locking conditions when:

[0162] 1) After the train routes are arranged and all the route signals for the arranged and combined routes are released, the train enters the approach lock section within the TCC-1 area. Arranging and combining train routes means checking whether there are any routes or combined routes (also called combined through routes) in CBI-1.

[0163] When the first train route is the receiving route (X->SI), and the approach locking section of the receiving route (X->SI) is included in the jurisdiction of the adjacent interlocking (CBI-N), the receiving route (X->SI) meets the approach locking conditions when:

[0164] 1) The station entry signal is open, and the adjacent interlock is behind the train approach route (X->SI). The JGJ relay driven by the adjacent interlock is lowered when CBI-1 collects the signal.

[0165] When the first train route is the departure route (XI->SF), and the approach locking section of the departure route (XI->SF) is included in the jurisdiction of the adjacent interlocking (CBI-N), the departure route (XI->SF) meets the approach locking conditions when:

[0166] 1) After the train routes are arranged and combined, and the route signals of the arranged and combined train routes are all open, CBI-1 collects the JGJ relay driven by the adjacent field interlocking (i.e. adjacent interlocking) and drops.

[0167] In an embodiment of the present invention, the method further includes first, in a station interlocking, establishing the following sub-scenarios based on the position of the approach locking section of the train route in the station interlocking: a first sub-scenario: the approach locking section of the train route is located between the first entry signal and the first exit signal in the station, a second sub-scenario: the approach locking section of the train route is located on the track in the station, and a third sub-scenario: the approach locking section of the train route is located between the second entry signal and the second exit signal in the station; then, when judging whether the first train route meets the approach locking condition in the second judgment scenario and the fourth judgment scenario, starting with the first sub-scenario, judging whether the first train route meets the approach locking condition in the corresponding sub-scenarios in the order from near to far of the approach locking sections in the station interlocking, wherein, when the first train route meets the approach locking condition in any corresponding sub-scenario or the first train route does not meet the approach locking condition in the sub-scenarios corresponding to all approach locking sections, the judgment is ended and the judgment result is obtained. Specifically, the first to third sub-scenarios are constructed from near to far according to the distance between the approach locking section and the train approach in the corresponding station, so that for each approach locking section of the train, it is possible to orderly check whether the train enters the approach locking range of the first train approach and whether the approach locking conditions of the first train approach will be triggered, thereby ensuring the safe operation of the train.

[0168] like Figure 5 As shown in the figure, scenario a, scenario b, and scenario c represent the first sub-scenario, the second sub-scenario, and the third sub-scenario. Figure 4For example, in CBI-2, determining whether the first train route meets the approach locking condition in the second determination scenario specifically includes the following steps:

[0169] Step S20: Determine whether the route signal behind the first train route is a section or whether the route signal behind the first train route is open. If the route signal behind the section or the rear route is open (i.e., one of the two conditions is met), execute step S21; otherwise, execute step S25.

[0170] Step S21: Determine whether the first train route's approaching locking section is within scenario a, scenario b, or scenario c. If so, proceed to step S211; otherwise, proceed to step S22. Because the locations of the approaching locking sections in scenarios a, b, and c are arranged in CBI-2 from near to far relative to the first train route, if there is a approaching locking section in scenario c, there must also be approaching locking sections in scenarios b and c. Conversely, if the train's furthest approaching locking section matches scenario a, then there are no approaching locking sections in the train route that match scenarios b and c.

[0171] Step S211: determine whether the train exit route is a train route. If so, execute step S212; otherwise, execute step S214.

[0172] Step S212: Determine whether the train has entered the train route after the route signal is opened. If so, execute step S24; otherwise, execute step S213; the route signal refers to the route signal of the train's exit route.

[0173] Step S213: After the route signal is released, determine whether the section within the train route is occupied by a fault. If so, execute step S24; otherwise, execute step S214;

[0174] Step S214: Determine whether the outbound route is a guided route. If so, execute step S215; otherwise, execute step S22.

[0175] Step S215: Determine whether the guide route signal is off and whether any section in the guide route is occupied. If the guide route signal is off and any section in the guide route is occupied, execute step S24; otherwise, execute step S22.

[0176] Step S22: Check whether the approach locking section of the first train route is in scenario b or scenario c. If so, execute step S221; otherwise, execute step S23.

[0177] Step S221: Determine whether the outbound route signal is open. If so, execute step S222; otherwise, execute step S23.

[0178] Step S222: Determine whether there is a vehicle occupying the track. If so, execute step S24; otherwise, execute step S23.

[0179] Step S23: Determine whether the approaching locking section of the first train route is in scenario c. If so, execute step S231; otherwise, execute step S25.

[0180] Step S231, determine whether the combined route signals are all open. If so, execute step S232, otherwise, execute step S25; by checking the combined route signals, ensure that the routes within the locked section are all allowed to pass, so that the train approach information can be passed down step by step.

[0181] Step S232: determine whether the train is running into the front route. If so, execute step S24; otherwise, execute step S233; the front route refers to the first route in the combined route in the direction of train travel.

[0182] Step S233: Determine whether any section in the preceding route is occupied. If so, proceed to step S24; otherwise, proceed to step S25.

[0183] Step S24: The first train route meets the approach locking condition, and step S26 is executed;

[0184] Step S25: The first train route does not meet the approach locking condition, and step S26 is executed;

[0185] Step S26: The adjacent station interlocking (CBI-2) sends the judgment result to the local station interlocking (CBI-1). Preferably, the local station interlocking can also obtain the judgment result of the adjacent interlocking through Ethernet communication.

[0186] Specifically, Figure 4 For example, when the approach locking section of the train route (SF->XI) of the local station interlocking (CBI-1) is in scenario a, that is, between the entry signal X and the exit signal SI of the adjacent station interlocking (CBI-2), the approach locking conditions are met when:

[0187] 1) The outbound approach is a train approach, the outbound approach signal (SI) is open, and the train enters the inner side of the outbound signal;

[0188] 2) The outbound route is a train route, the outbound route signal (SI) is open, and any section within the outbound route is occupied;

[0189] 3) The outbound route is a train route, the outbound route signal (SI) is open, and the section fault in the outbound route is occupied;

[0190] 4) The exit route is a guided route, the guided route signal (SI) is opened and then closed, and there is a vehicle occupying the section within the route.

[0191] When the approach locking section of the train route (SF->XI) of the local interlocking (CBI-1) is in scenario b, that is, when the track of the interlocking CBI-2 is connected at the adjacent station, the approach locking conditions are met as follows:

[0192] 1) When arranging the departure route (SI->X), after the exit signal (SI) is released (i.e., the exit route signal is open), there is a train occupying the track (IG). Arranging the departure route means checking whether the route signal ahead of the track is open. This is a check of the route's normal operation, ensuring safe train operation.

[0193] When the approach locking section of the train route (SF->XI) of the local interlocking (CBI-1) is in scenario c, that is, between the entry signal SF and the exit signal XI of the adjacent station interlocking CBI-2, the train route (SF->XI) of the local interlocking (CBI-1) meets the approach locking conditions in the following situations:

[0194] 1) When a train is running, both signals on the combined approach (SF->IG->X) are open (i.e., SF and SI are open), and the train approaches the inner side of the SF approach signal. This means that if the train is to enter the (SF->IG) approach, the SF signal must be open. If the approach lock information needs to be passed down the chain, the signal on the (IG->X) approach must also be open. This serves as a check on the approach's normal operation, ensuring safe train operation.

[0195] 2) During non-train operation, the combined approach (SF->IG->X) is fully locked, the exit approach signal (SI) is open, and any section within the receiving approach is occupied. During non-train operation, including fault conditions, if the station interlocking system detects an occupied section within the first approach, it is considered a train has entered the approach, triggering the approach locking condition.

[0196] In the embodiment of the present invention, in the third judgment scenario, it is determined whether the first train route meets the approach locking condition, such as Figure 6 As shown, the specific steps include:

[0197] Step S31: Determine whether the route signal of the first train route is behind a section or whether the route signal of the route behind the first train route is open. If the route signal of the section or the route signal of the route behind the first train route is open, execute step S32; otherwise, execute step S36;

[0198] Step S32: interlocking with adjacent stations in the section where the block section is located under the third determination scenario to obtain the block partition status of the section where the block section is located under the third determination scenario;

[0199] Step S33: Determine whether the approach locking section of the first train route is occupied. If so, execute step S34; otherwise, execute step S36.

[0200] Step S34: Determine whether there is a combined through route in the adjacent station in the section close to the locked section in the third determination scenario and whether the route signal of the combined through route is open. If there is a combined through route and the route signal of the combined through route is open, execute step S35; otherwise, execute step S36.

[0201] Step S35: The first train route satisfies the approach locking condition. The judgment result is sent to the station interlocking through one or more station interlockings step by step. Each time the train passes through a station, the corresponding station interlocking determines whether there is a combined through route in the station and whether the route signal of the combined through route is open. If there is a combined through route and the route signal of the combined through route is open, the first train route satisfies the approach locking condition in the corresponding station interlocking. If the first train route satisfies the approach locking condition in all the station interlockings step by step, the judgment result is finally sent to the station interlocking. Otherwise, step S36 is executed.

[0202] Step S36: The first train route does not meet the approach locking condition, and the judgment result is sent to the station interlocking step by step through one or more station interlockings.

[0203] Still Figure 4 For example, the approach lock section of the vehicle receiving route (SF->XI) in CBI-1 is under the jurisdiction of TCC-2, such as Figure 6As shown, CBI-2 first determines whether the approaching locking section within the jurisdiction of TCC-2 meets the approaching locking conditions. That is, CBI-2 obtains the block section status of the adjacent section (TCC-2) to check whether the train enters the approaching locking section within the jurisdiction of TCC-2. If it does, it further checks whether there is a combined through route in its own station and whether the route signal of the combined through route is open. For example, CBI-2 has a (SF->X) combined through route. After the SF and SI signals are open, the judgment result of CBI-2 is that the receiving route (SF->XI) meets the approaching locking conditions, then CBI-2 sends the judgment result to CBI-1. For example, if the approach locking section is in the adjacent section of CBI-3, when CBI-3 checks whether the approach locking section in the adjacent section meets the requirements, it checks whether there is a combined through route in the CBI-3 station and whether the route signal of the combined through route is open. If both are met, the vehicle receiving route (SF->XI) meets the approach locking conditions in CBI-3, and the judgment result is sent to CBI-2. CBI-2 then checks whether there is a combined through route in the station and whether the route signal of the combined through route is open. If both conditions are met, the receiving route (SF->XI) also meets the proximity locking condition in CBI-2, and the judgment result is sent to CBI-1, and it is finally concluded that the receiving route (SF->XI) meets the proximity locking condition; on the contrary, if the receiving route (SF->XI) does not meet the proximity locking condition in CBI-3, CBI-3 sends the judgment result to CBI-2, and CBI-2 sends the judgment result to CBI-1, and it is concluded that the receiving route (SF->XI) does not meet the proximity locking condition.

[0204] In the embodiment of the present invention, in the fourth determination scenario, it is determined whether the first train route meets the approach locking condition, such as Figure 7 As shown, the specific steps include:

[0205] Step S41: Determine whether the route signal of the first train route is behind a section or whether the route signal of the route behind the first train route is open. If the route signal of the first train route is behind a section or the route signal of the route behind the first train route is open, execute step S42; otherwise, execute step S44;

[0206] Step S42: Determine whether the first train route meets the approach locking condition at the station where the approach locking section of the first train route is located. Figure 5 The judgment method in the adjacent station interlocking (CBI-2) shown is not repeated here. If the conditions are met, step S43 is executed; otherwise, step S44 is executed.

[0207] Step S43: Send the judgment result to the station interlocking system through one or more station interlocking systems step by step. At each station passed, the corresponding station interlocking system judges whether there is a combined through route in the station and whether the route signal of the combined through route is open. If there is a combined through route and the route signal is open, the first train route satisfies the approach locking condition in the corresponding station interlocking system. If the first train route satisfies the approach locking condition in all the station interlocking systems step by step, the judgment result is finally sent to the station interlocking system. Otherwise, execute step S44.

[0208] Step S44: The first train route does not meet the approach locking condition, and the judgment result is sent to the station interlocking step by step through one or more station interlockings.

[0209] Still Figure 4 For example, the approach locking section of the train route is under the jurisdiction of the station interlocking behind the adjacent station interlocking, that is, the approach locking section of the train route is in other station interlockings behind the adjacent station interlocking, wherein Ethernet communication (or relay interface communication) exists between the various station interlockings. For example, Figure 7 As shown, the approach locking section of the vehicle receiving route (SF->XI) in CBI-1 is under the jurisdiction of CBI-3 interlocking. Figure 5 The judgment method in CBI-2 shown above determines whether the train's current position meets the proximity locking conditions of the route to be inspected. Specifically, it determines whether the train has entered the proximity locking range of the first train route and whether the proximity locking conditions of the first train route have been triggered. CBI-3 sends the judgment result to CBI-2. If the locking conditions are met, CBI-2 then determines whether a combined through route exists within the station. If a combined through route exists and its SF and SI signals are enabled, the receiving route (SF->XI) meets the proximity locking conditions. A combined through route in CBI-2 can be (SF->X). Furthermore, if the proximity locking conditions are not met in CBI-3 or CBI-2, the judgment result indicating that (SF->XI) does not meet the proximity locking conditions is directly passed on step by step until it reaches CBI-1.

[0210] In the embodiment of the present invention, both the receiving and dispatching routes are straight routes or the lateral switches passed through are No. 18 or higher. In addition, the present invention is applicable to computer interlocking systems for high-speed railways with operating speeds exceeding 350 km / h (kilometers per hour), or computer interlocking systems in which the approach section of the train route at the station exceeds the length of the adjacent section or the length of the adjacent section plus the adjacent station.

[0211] like Figure 8As shown, an embodiment of the present invention further discloses a computer interlocking train route approach locking determination system capable of executing the above method, wherein the system includes a building module, an acquisition module and a determination module, wherein the building module is used to build the following determination scenarios based on the position of the train route approaching the locking section: the first determination scenario: the approaching locking section of the train route is included in the jurisdiction of the adjacent section of the station, the jurisdiction of the interlocking of the station or the jurisdiction of the adjacent interlocking of the station; the second determination scenario: the approaching locking section of the train route is within the jurisdiction of the interlocking of the adjacent station; the third determination scenario: the approaching locking section of the train route is within the jurisdiction of the adjacent section of the station behind the train route; the Four judgment scenarios: the approach locking section of the train route is within the jurisdiction of the rear station interlocking of the adjacent station; the acquisition module is used to obtain the first train route with an open signal, determine all the approach locking sections of the first train route and the judgment scenarios where all the approach locking sections are located; the judgment module is used to start with the first judgment scenario, and judge whether the first train route meets the approach locking conditions in the corresponding judgment scenarios in the order of the approach locking sections from near to far, wherein, when the first train route meets the approach locking conditions in any corresponding judgment scenario or the first train route does not meet the approach locking conditions in the judgment scenarios corresponding to all the approach locking sections, the judgment is ended and the judgment result is obtained. Furthermore, the construction module is also used to construct the following sub-scenarios in a station interlocking based on the position of the approach locking section of the train route in the station interlocking: the first sub-scenario: the approach locking section of the train route is located between the first entry signal and the first exit signal in the station, the second sub-scenario: the approach locking section of the train route is located on the track in the station, and the third sub-scenario: the approach locking section of the train route is located between the second entry signal and the second exit signal in the station; the judgment module is also used to judge whether the first train route meets the approach locking condition in the second judgment scenario and the fourth judgment scenario, starting with the first sub-scenario, and judging whether the first train route meets the approach locking condition in the corresponding sub-scenarios in the order from near to far of the approach locking sections in the station interlocking, wherein, when the first train route meets the approach locking condition in any corresponding sub-scenario or the first train route does not meet the approach locking condition in the sub-scenarios corresponding to all approach locking sections, the judgment is ended and the judgment result is obtained.

[0212] The determination module is also used to determine whether the first train route meets the approach locking condition in the first determination scenario. The specific steps are as follows: Figure 3 As shown, no further details will be given here.

[0213] The determination module is further configured to determine whether the first train route satisfies the approach locking condition in the second determination scenario, specifically comprising the following steps: Figure 5 As shown, no further details will be given here.

[0214] The determination module is further configured to determine whether the first train route satisfies the approach locking condition in a third determination scenario, specifically comprising the following steps:

[0215] Step S31: Determine whether the route signal of the first train route is behind a section or whether the route signal of the route behind the first train route is open. If the route signal of the section or the route signal of the route behind the first train route is open, execute step S32; otherwise, execute step S36;

[0216] Step S32: interlocking with adjacent stations in the section where the block section is located under the third determination scenario to obtain the block partition status of the section where the block section is located under the third determination scenario;

[0217] Step S33: Determine whether the approach locking section of the first train route is occupied. If so, execute step S34; otherwise, execute step S36.

[0218] Step S34: Determine whether there is a combined through route in the adjacent station in the section close to the locked section in the third determination scenario and whether the route signal of the combined through route is open. If both the combined through route and the route signal are open, execute step S35; otherwise, execute step S36.

[0219] Step S35: If the first train route satisfies the approach locking condition, the judgment result is transmitted to the station interlocking through one or more station interlocking systems step by step. Each time the train passes through a station, the corresponding station interlocking system determines whether there is a combined through route in the station and whether the route signal of the combined through route is open. If there is a combined through route and the route signal is open, the first train route satisfies the approach locking condition in the corresponding station interlocking system. If the first train route satisfies the approach locking condition in all the station interlocking systems that transmit the judgment result step by step, the judgment result is finally transmitted to the station interlocking system. Otherwise, step S36 is executed.

[0220] Step S36: The first train route does not meet the approach locking condition, and the judgment result is sent to the station interlocking step by step through one or more station interlockings.

[0221] The determination module is further configured to determine whether the first train route satisfies the approach locking condition in a fourth determination scenario, specifically comprising the following steps:

[0222] Step S41: Determine whether the route signal of the first train route is behind a section or whether the route signal of the route behind the first train route is open. If the route signal of the section or the route signal of the route behind the first train route is open, execute step S42; otherwise, execute step S44.

[0223] Step S42: Determine whether the first train route meets the approach locking condition at the station where the approach locking section of the first train route is located. Figure 5 The judgment method in interlocking with adjacent stations (CBI-2) is as follows: if the conditions are met, step S43 is executed; otherwise, step S44 is executed;

[0224] Step S43: The determination result of whether the first train route meets the approach locking condition is transmitted to the station interlocking through one or more station interlockings step by step. Each time the train passes through a station, the corresponding station interlocking determines whether there is a combined through route in the station and whether the route signal of the combined through route is open. If there is a combined through route and the route signal is open, the first train route meets the approach locking condition in the corresponding station interlocking. If the first train route meets the approach locking condition in all the station interlockings to which the determination result is transmitted step by step, the determination result is finally transmitted to the station interlocking. Otherwise, step S44 is executed.

[0225] Step S44: The first train route does not meet the approach locking condition, and the judgment result is sent to the station interlocking step by step through one or more station interlockings.

[0226] In the embodiment of the present invention, any station interlocking and the corresponding adjacent station interlocking, any station interlocking and the corresponding adjacent section, and any station interlocking and the corresponding adjacent interlocking all communicate via Ethernet or relay interface.

[0227] In the embodiment of the present invention, both the receiving and departing routes are straight routes or the lateral switches passed by are No. 18 or above.

[0228] The determination system judges the conditions for approaching locking of train routes for various scenarios where train routes approach locking sections, and effectively determines the approaching locking of high-speed train routes where the approaching locking sections are located in distant sections or interlocking stations, while ensuring safety and operational efficiency.
