Description

Technical Field

[0001] The present disclosure relates to the field of rail transit, and particularly to a method for tracking and screening the positions of faulty trains. Background Art

[0002] The full-automatic operation signal system for regional rail transit realizes moving block through information transmission between the ground control system and the on-vehicle system. The full-automatic operation signal system for regional rail transit includes: Train Integrated Automation System (TIAS), Zone Controller (ZC), Data Storage Unit (DSU), Computer Interlocking (CI), Vehicle On Board Control (VOBC), etc. Among them, ZC is used to receive the position information of VOBC, the line status information reported by CI, the data version reported by DSU, and the temporary speed limit information for the whole line in real time, and calculate the Moving Authority (MA) for the train according to the above information. After receiving the MA from ZC, VOBC can be upgraded to run in Communication-Based Train Control System (CBTC). One of the necessary conditions for ZC to calculate MA is to screen the train to confirm whether there are suspicious vehicles without position reports hidden in front of the train. There are efficiency problems in the fault recovery of two types of trains in the prior art: one is that when the train loses its position due to communication failure, self-positioning failure, etc. during operation, ZC cannot calculate the moving authority for the train normally. Wait for the train to recover from the fault and report its position again. It is necessary to screen the front end of the train, that is, to ensure that the distance between the head position of the train and the idle axle counting section in front is less than the minimum vehicle length of the line. After confirming that there are no suspicious vehicles, calculate MA; the other is that communication trains (including CBTC-level trains and communication trains that have not been upgraded to CBTC level yet) have added front-end suspicious marks due to abnormalities or unknowns in the front area, and need to re-complete the front-end screening. If the above two types of trains appear in large and long axle counting sections in the interval, the recovery efficiency is extremely low; in the case of driverless operation, the driver needs to get back on the train or run at a low speed through remote control until the train completes the screening and meets the upgrade conditions. Summary of the Invention

[0011] In some implementable ways of the first aspect, if the faulty train breaks into the turnout and the turnout is in the four-way open position and the signal is closed, it is confirmed that the axle counter section occupied by the faulty train is the axle counter section occupied by itself and the first axle counter section in the normal and reverse positions of the turnout.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0034] In addition, the term "and / or" in this document is merely a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally represents an "or" relationship between the front and rear associated objects.

[0035] In response to the problems mentioned in the background art, the embodiments of the present disclosure provide a method for tracking and screening the position of a faulty train.

[0036] Specifically, the DSU tracks the position of the faulty train based on the occupation of the axle counting section by the faulty train and the screening of the communicating trains before and after the occupied axle counting section. When the faulty train resumes communication, the information of the occupied axle counting section is updated, and the ZC assists the communicating trains to complete the screening according to the information of the occupied axle counting section. In this way, it can assist the faulty train whose position reporting has been restored and other communicating trains to quickly conduct screening and upgrade, effectively improving the train operation efficiency.

[0037] The following will combine the accompanying drawings and elaborate on the method for tracking and screening the position of a faulty train provided by the embodiments of the present disclosure through specific embodiments.

[0038] Figure 1 The flowchart of a method for tracking and screening the position of a faulty train provided by an embodiment of the present disclosure is shown; as Figure 1 shown, the method 100 for tracking and screening the position of a faulty train may include the following steps:

[0039] S110, record the position where the faulty train is located when a communication failure occurs, and track the position of the faulty train according to the occupation of the axle counting section by the faulty train and the screening of the communicating trains before and after the occupied axle counting section;

[0040] Specifically, when a communication failure occurs and the train is disconnected, the area controller records the position where the faulty train is located. At the same time, the data storage unit tracks the position of the faulty train according to the occupation of the axle counting section by the faulty train and the screening of the communicating trains before and after the occupied axle counting section.

[0041] In some embodiments, the axle counting section occupied by the faulty train is confirmed according to the axle counting section information of the faulty train and the turnout state in the driving direction; wherein, the axle counting section information includes: the states of the front and rear axle counting sections in the driving direction of the faulty train, and the states of the communicating trains on the front and rear axle counting sections.

[0042] In some embodiments, if the first adjacent axle counting section in the driving direction of the faulty train is in the idle state in both the previous period and the current period, it is confirmed that the axle counting section occupied by the faulty train itself is the current axle counting section; if the first adjacent axle counting section is in the idle state in the previous period and the occupied state in the current period, and the second adjacent axle counting section is in the idle state in both the previous period and the current period, it is confirmed that the axle counting section occupied by the faulty train itself is the current axle counting section and the first adjacent axle counting section.

[0043] Specifically combined with Figures 2 - 3 for a detailed description, Figures 2 - 3 The schematic diagram of a single faulty train scenario provided by an embodiment of the present disclosure is shown;

[0044] As Figure 2As shown, when the first adjacent axle counter section in the traveling direction of the faulty train is in the idle state in the current cycle and this cycle is also in the idle state, the axle counter section occupied by the faulty train itself is its current axle counter section.

[0045] As Figure 3 shown, when the first adjacent axle counter section in the traveling direction of the faulty train is in the idle state in the previous cycle and is in the occupied state in this cycle, and the second adjacent axle counter section ahead is in the idle state in both the previous cycle and this cycle, the axle counter sections occupied by the faulty train itself are its current axle counter section and the first adjacent axle counter section.

[0046] According to the embodiments of the present disclosure, by confirming the axle counter sections occupied by the faulty train itself, the axle counter sections occupied by the faulty train in more complex scenarios can be clarified, without calculating whether the distance between the head position of the train and the idle axle counter section ahead is less than the minimum vehicle length of the line, making the tracking of the position of the faulty train faster and more convenient.

[0047] In some embodiments, there can be multiple faulty trains in a single axle counter section.

[0048] Specifically combined with Figure 7 for detailed description, Figure 7 shows a schematic diagram of a scenario where there are multiple faulty trains in a single axle counter section provided by the embodiments of the present disclosure;

[0049] As Figure 7 shown, if there are multiple faulty trains in a single axle counter section and the adjacent axle counter sections are in the idle state, then the axle counter sections occupied by the multiple faulty trains are all the current axle counter section.

[0050] If there are multiple faulty trains in a single axle counter section and the adjacent axle counter sections are in the occupied state, at this time, it is impossible to confirm which faulty train occupies the adjacent axle counter section, then the axle counter sections occupied by the multiple faulty trains are all the current axle counter section and the adjacent axle counter section.

[0051] In some embodiments, if there is a screened communication train on any axle counter section in front of or behind the faulty train, then it is confirmed that the axle counter section occupied by the faulty train is the axle counter section occupied by itself; if there is an unscreened communication train on any axle counter section in front of or behind the faulty train, then it is confirmed that the axle counter section occupied by the faulty train is the axle counter section occupied by itself and the axle counter section occupied by the communication train.

[0052] Specifically combined with Figures 4 - 6 and Figure 10 for detailed description.

[0053] Figure 4 shows a schematic diagram of a scenario when there is an unscreened communication train in the adjacent axle counter section in front of the faulty train provided by the embodiments of the present disclosure;

[0054] As Figure 4 shown, there is a communication train with uncompleted back-end screening in the adjacent axle counter section that the faulty train occupies on its own in the driving direction of the faulty train. At this time, the axle counter section occupied by the faulty train is the axle counter section it occupies on its own and the axle counter section occupied by the communication train ahead.

[0055] Figure 5 The figure shows a schematic diagram of the scenario when there is a communication train with completed screening in the adjacent axle counter section in front of the faulty train provided by the embodiment of the present disclosure;

[0056] As Figure 5 shown, there is a communication train with completed back-end screening in the axle counter section in the driving direction of the faulty train. At this time, the axle counter section occupied by the faulty train is the axle counter section it occupies on its own.

[0057] Figure 6 The figure shows a schematic diagram of the scenario when there is a communication train with uncompleted screening in the non-adjacent axle counter section in front of the faulty train provided by the embodiment of the present disclosure;

[0058] As Figure 6 shown, there is a train with uncompleted back-end screening in the non-adjacent axle counter section in the driving direction of the faulty train. At this time, the axle counter section occupied by the faulty train is the axle counter section it occupies on its own and the axle counter section occupied by the communication train ahead.

[0059] In some embodiments, the axle counter sections expressing the positions of the trains are not necessarily continuously adjacent. As Figure 6 shown, the position of the faulty train is the axle counter section it occupies on its own and the axle counter section occupied by the communication train ahead, that is, Figure 6 a, b, and c in

[0060] In some embodiments, there are communication trains with uncompleted screening both in front of and behind the faulty train. As Figure 10 shown, at this time, the axle counter section occupied by the faulty train is the axle counter section it occupies on its own and the axle counter sections occupied by the communication trains in front of and behind it, that is, Figure 10 a, b, c, and d in

[0061] According to the embodiment of the present disclosure, on the basis of confirming the axle counter section that the faulty train occupies on its own, the axle counter sections occupied by multiple faulty trains are clarified, realizing the tracking of the positions of multiple faulty trains.

[0062] In some embodiments, if the faulty train breaks into the switch and the switch is in the four-way open position and the signal is off, it is confirmed that the axle counter section occupied by the faulty train is the axle counter section it occupies on its own and the first axle counter section in the normal and reverse positions of the switch.

[0063] Specifically, it is described in detail in combination with Figures 8 - 9 this.

[0064] Figure 8 Shows a schematic diagram of the scenario where the switch in front of the axle counter section where the faulty train is located is in the four-way position and the signal is closed, provided by an embodiment of the present disclosure;

[0065] As Figure 8 shown, the switch in front of the axle counter section where the faulty train is located is in the four-way position and the signal is closed. At this time, if the faulty train continues to move forward, it will break into the switch.

[0066] Figure 9 Shows a schematic diagram of the scenario when the faulty train breaks into the switch in front and the switch is in the four-way position, provided by an embodiment of the present disclosure;

[0067] As Figure 9 shown, the faulty train breaks into the switch, and the axle counter sections in front of the normal and reverse positions of the switch are in the occupied state. ZC cannot confirm the direction of the faulty train. Therefore, the axle counter sections occupied by the faulty train are its own occupied axle counter sections and the first axle counter section in the normal and reverse directions of the switch, that is Figure 9 the a, b, c, and d sections in

[0068] According to the embodiments of the present disclosure, the axle counter sections occupied by the faulty train in complex scenarios are clarified. In this way, it can effectively assist in quickly screening and upgrading the faulty train with restored position reporting and other communication trains.

[0069] S120. When the faulty train resumes communication, update the information of the occupied axle counter sections, and assist the communication trains to complete the screening according to the information of the occupied axle counter sections.

[0070] In some embodiments, the communication trains that need to be screened can be the following two types:

[0071] One type is the faulty train with restored position reporting; the other type is the train with a suspicious mark re-added due to the unknown front area.

[0072] In some embodiments, the faulty trains with restored position reporting can be the trains in the following scenarios:

[0073] Trains that resume position reporting after their own positioning fails; for example, the train drives into a switch with an unknown state or the train speed measurement and distance measurement system fails.

[0074] Trains with a preset non-CBTC level that do not communicate with ZC and are manually upgraded to the CBTC level and start reporting their positions after the upgrade.

[0075] Trains that resume position reporting after a communication failure with ZC.

[0076] Trains that resume after a communication failure between the CI in the operating area and ZC; when there is a communication failure between ZC and CI, the trains will be deleted for safety reasons, and the trains need to report their positions again.

[0077] Trains with CI-ZC communication failures in the operating area and entering the next CI jurisdiction area.

[0078] In some embodiments, trains that have added suspicious marks due to unknown areas ahead can be trains in the following scenarios:

[0079] When multiple CBTC trains are in pursuit, a failure of the leading train causes the current train to make an emergency brake.

[0080] The area ahead of the CBTC train is an unknown failure area, resulting in the ZC failing to calculate the MA for the train.

[0081] The CBTC train operates within the handover ZC range, and a communication failure between the handover ZC and the takeover ZC causes the current train to make an emergency brake.

[0082] In the case where one ZC manages multiple interlocking control areas, when the CBTC train operates within the CI1 control area and the ZC determines a communication failure with CI2 at this time, the current train makes an emergency brake after receiving the ZC notice.

[0083] According to the embodiments of the present disclosure, the above two types of communication trains that need to be screened can be quickly screened, effectively improving the operation efficiency of the trains.

[0084] In some embodiments, the ZC assists in screening communication trains according to the occupied axle counting section information, including:

[0085] If when a failed train resumes communication, only the failed train that resumes communication exists in its occupied axle counting section, then the failed train that resumes communication is exempt from screening, and the communication trains on its adjacent axle counting sections can also be exempt from screening, thereby realizing the rapid screening of the failed train that resumes communication and the communication trains on its adjacent axle counting sections.

[0086] In some embodiments, the ZC assisting in screening communication trains according to the occupied axle counting section information further includes:

[0087] If when a failed train resumes communication, there are communication trains with suspicious marks in the adjacent axle counting sections before and after its occupied axle counting section, then it is determined whether only the communication train exists in the occupied axle counting section of the communication train; if only the communication train exists, then the communication train can be exempt from screening, thereby realizing the rapid screening of the communication trains with suspicious marks.

[0088] Specifically combined with Figure 10 For a detailed description.

[0089] Such as Figure 10As shown in the figure, when the failed train resumes communication, there are communication trains with suspicious marks in front of and behind the axle-counting section occupied by the failed train itself. At this time, the ZC determines whether there is only itself in the axle-counting section where each of the communication trains in front of and behind is located; if the ZC determines that there is only itself in the axle-counting section occupied by each of the communication trains in front of and behind, then the two communication trains in front of and behind the failed train are exempt from screening, and the axle-counting section occupied by the failed train that resumes communication changes from a, b, c, d to b, c.

[0090] According to the embodiments of the present disclosure, the following technical effects are achieved:

[0091] Compared with the traditional screening scheme, the method for tracking and screening the position of a failed train provided by the present disclosure tracks the position of the failed train according to the axle-counting section occupied by the failed train and the screening conditions of the communication trains in front of and behind the axle-counting section, without calculating whether the distance from the head position of the train to the idle axle-counting section in front is less than the minimum train length of the line. In this way, it can assist the failed train that resumes position reporting and other communication trains to quickly screen and upgrade, effectively improving the train operation efficiency.
