Description

Technical Field

[0001] The present invention relates to a rail transit signal system, and in particular to a method, a device and a medium for releasing a section fault protection zone of a CTCSN. Background Art

[0002] CTCS (China Train Control System) is a train control system designed to ensure safe train operation and meet the transportation needs of different lines in a graded manner, including ground equipment and on-board equipment. The current mainstream train control systems include CTCS0 ​​(China Train Control System Level 0), CTCS2 (China Train Control System Level 2) and CTCS3 (China Train Control System Level 3). CTCSN (New China Train Control System) is a new train control system developed by China State Railway Group Co., Ltd. Compared with the current mainstream train control system, it uses new technologies such as mobile blocking, Beidou positioning, and 5G communication, and is suitable for freight lines that need to be transformed to improve transportation capacity.

[0003] The no-tail screen in the CTCSN system means that there may be unknown vehicles behind the train in the section where the train is located. Completing the tail screen means confirming that there are no unknown vehicles behind the train by automatic or manual means. The no-tail screen of the train will generate a fault protection zone to ensure the safety of train operation.

[0004] When the train is initially registered to the RBC subsystem in the interval virtual section, the train tail screen state is initial no tail screen. When the train tail screen state is initial no tail screen and there is no fault protection zone behind the train, an initial no tail screen fault protection zone will be generated, the starting point of the protection zone is the interval station boundary and the end point is the rear of the train.

[0005] The initial tailless screen generation fault protection zone in CTCSN is a new function point, which is crucial to the safety of interval driving. Therefore, a detailed test plan needs to be designed for this new function to fully verify its correctness.

[0006] When a train is initially registered in a section, a fault protection zone will be generated in the entire section. When there is a fault protection zone in the section, the train cannot be tracked in the moving block mode, which affects the driving efficiency of the section. To remove the fault protection zone generated by the initial registration of the train section, the train, RBC (Radio Block Center), and CTC (Centralized Control System) subsystems need to cooperate with each other correctly.

[0007] When a train initially registers and generates a fault protection zone in a section, the current common practice is to downgrade the train's operating mode, and restore the section to moving block mode after the train leaves the current section. This will greatly reduce the running efficiency of the section train. In addition, the initial generation of a fault protection zone without a tail screen in CTCSN is a new function, and there is currently no scenario analysis and test verification solution for this function.

[0008] Therefore, how to design a method to release the fault protection zone caused by the initial registration of the train section in CTCSN, so as to quickly restore the section to a moving block mode with high driving efficiency, becomes a technical problem that needs to be solved. Summary of the invention

[0009] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a method, device and medium for removing the interval fault protection zone of CTCSN.

[0010] The purpose of the present invention can be achieved by the following technical solutions:

[0011] According to a first aspect of the present invention, a method for releasing an interval fault protection zone for CTCSN is provided. The method first determines whether the CTCSN system can release the fault protection section with a vehicle. If so, a processing procedure for releasing the fault protection section with a vehicle is adopted. Otherwise, a processing procedure for not releasing the fault protection section with a vehicle is adopted, and an expected result judgment corresponding to the operation steps is added in the two processing procedures.

[0012] As a preferred technical solution, before the CTCSN system determines whether to release the fault protection section with a train, this method first runs the train to the virtual section of the interval for initial registration, and automatically sets the entire section as a fault protection section, that is, the system generates fault protection for the entire section by itself without manual setting.

[0013] As a preferred technical solution, the process of removing the fault protection section with a vehicle specifically includes the following steps:

[0014] Step 101, sequentially issuing virtual section idle commands to release the section fault protection behind the section where the train is located;

[0015] Step 102, issuing a virtual section idle command, releasing the fault protection of the section where the train is located, and regenerating a fault protection zone behind the train;

[0016] Step 103, a command to complete the tail screen is issued to the train, and the train completes the tail screen;

[0017] Step 104, the virtual section idle command is issued again in sequence, and the rear section fault protection of the section where the train is located is released again;

[0018] Step 105, issuing a virtual section idle command again, releasing the fault protection of the section where the train is located, and no fault protection zone is regenerated behind the train;

[0019] Step 106, issuing a virtual section idle command to sequentially release the fault protection of the section ahead of the train;

[0020] Step 107, a command to complete the first screening is issued to the train, and the train completes the first screening and enters the normal operation mode; the rear train can depart from the rear station and enter the section in the moving block mode, and can closely track the front train.

[0021] As a preferred technical solution, in steps 101 and 104, a virtual segment idle command is issued from the CTC.

[0022] As a preferred technical solution, the order in steps 101 and 104 is from the station boundary to the train direction.

[0023] As a preferred technical solution, in step 103, a tail screen command is issued from the CTC to release the train's initial tail screen-free state.

[0024] As a preferred technical solution, the process of handling the fault protection section where the vehicle cannot be released specifically includes the following steps:

[0025] Step 201, sequentially issuing virtual section idle commands to release the rear section fault protection of the section where the train is located;

[0026] Step 202, a command to complete the tail screening is issued to the train, and the train completes the tail screening;

[0027] Step 203, a command to complete the first screening is issued to the train, and the train completes the first screening;

[0028] Step 204, issue a virtual section idle command, sequentially release the fault protection of the section ahead of the train; the train enters the normal operation mode; the rear train can depart from the rear station and enter the section in the moving block mode, and can closely track the front train.

[0029] As a preferred technical solution, in steps 201 and 204, a virtual segment idle command is issued from the CTC.

[0030] As a preferred technical solution, in step 202, a tail screen command is issued from the CTC to release the train's initial tail screen-free state.

[0031] As a preferred technical solution, the expected result corresponding to the operation steps is specifically determined as follows:

[0032] When the execution results of the corresponding steps in the processing flow are completely consistent with expectations, it means that the function of generating fault protection zones by the initial tailless screen of the interval in the CTCSN system under test is correct.

[0033] According to a second aspect of the present invention, there is provided an electronic device, comprising a memory and a processor, wherein a computer program is stored in the memory, and the method described above is implemented when the processor executes the program.

[0034] According to a third aspect of the present invention, there is provided a computer-readable storage medium having a computer program stored thereon, wherein the program implements the method described above when executed by a processor.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] 1) The present invention proposes a method for removing the fault protection zone caused by the initial registration of a train section in CTCSN. The method can smoothly remove the fault protection zone caused by the initial registration of a train section in CTCSN systems under two different configurations, and quickly restore the section to a moving block mode with high driving efficiency.

[0037] 2) The present invention designs a method for removing the fault protection zone caused by the initial registration of the train section, and divides the method into two types according to whether the CTCSN system can remove the fault protection of the section with vehicles. This method can be used to manually and quickly remove the section fault protection, so that the section can quickly return to the moving block mode. Compared with the original scheme of driving out of the section in a downgraded train mode, the present invention can greatly improve the traffic efficiency of the section train.

[0038] 3) The present invention analyzes the characteristics of the fault protection zone generated by the initial tailless screen, and by adding the expected result judgment corresponding to each step in the fault removal method, the fault removal method also becomes a test method for verifying the new functional point of the initial tailless screen generating the fault protection zone. The present invention can be executed to verify whether the function of the initial tailless screen generating the fault protection zone in the CTCSN system is correct.

[0039] 4) The present invention analyzes in detail the characteristics of the new function of generating fault protection zone by initial tailless screen during train section registration in CTCSN, and proposes a test verification method for this function point, filling the gap in the current CTCSN system's initial tailless screen generating fault protection zone function test method. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 This is a schematic diagram of two stations and one section;

[0041] Figure 2 It is a specific flow chart of the method of the present invention. DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work should fall within the scope of protection of the present invention.

[0043] The present invention deeply studies the relevant schemes for releasing the fault protection zone in CTCSN, designs a method for manually releasing the fault protection zone generated by the initial registration of the train section; at the same time, the expected results of the relevant operations are added to the steps of the method to verify the correctness of the function of generating the fault protection zone by the initial tailless screen in the CTCSN system.

[0044] The present invention analyzes the functional characteristics of the initial tailless screen generating fault protection zone for interval trains in the CTCSN system, analyzes various operation commands for manually releasing the fault protection zone, designs a method for releasing the fault protection zone generated by the initial registration of the train interval, and verifies the correctness of the function of the initial tailless screen generating fault protection zone.

[0045] like Figure 1 As shown, it is used as an example to illustrate the train operation line scenario of the present invention.

[0046] The train departs from station 1 and runs to the virtual section X3G. After the initial registration with RBC, the tail screen status is initially no tail screen.

[0047] At this time, if there is no fault protection zone behind the train, the initial tailless screen will generate a fault protection zone, with the starting point being the station boundary between station 1 and the section and the end point being the rear of the train.

[0048] If there is a fault protection zone behind the train when registering to RBC, the initial fault protection zone without tail screen will not be generated first. The initial fault protection zone without tail screen will be generated after the original fault protection zone is released.

[0049] If a section is occupied by a fault, the CTC can manually send a section idle command to release the fault occupation of the section. When multiple consecutive sections need to be released, they need to be released in the order of the direction of the train running.

[0050] Manually issuing the tail screen command from CTC can release the fault protection zone from the start point to the rear of the train section. Manually issuing the head screen command from CTC can release the fault protection zone from the front of the train to the end of the train section. When issuing the head screen and tail screen commands through CTC to release the fault protection zone of the train section, it is necessary to release the tail screen first and then the head screen in this order.

[0051] In addition, when removing the faulty section, if there is a car in the section, whether the CTC issues the section idle command successfully or not can be configured in the CTCSN system. According to the two different configurations, two different solutions need to be designed to remove the initial tailless screen.

[0052] The specific process of the present invention is as follows:

[0053] According to whether the CTCSN system can release the fault protection section with a vehicle, the initial fault relief without a tail screen is divided into two schemes: Scheme A corresponds to the fault protection section with a vehicle and scheme B corresponds to the fault protection section with a vehicle.

[0054] Add the expected results corresponding to the operation steps in the plan. When the execution results of the corresponding steps are completely consistent with the expectations when the plan is executed, it means that the function of generating fault protection zone by initial tailless screen of interval in the CTCSN system under test is correct, and the fault elimination plan also becomes the test method of this function.

[0055] Initial scenario: The train runs to the initial registration of the virtual section X3G in the interval. At this time, because the train enters the interval, the CTCSN system detects that there is a car in the interval, and will first set the entire interval to fault protection. X1G, X2G, X3G, and X4G will all generate fault protection areas. At this time, the tail screen state of the train is the initial no tail screen.

[0056] Option A:

[0057] The virtual section idle command is issued from CTC, and the faulty sections are released in sequence from the station boundary to the train direction, and the X1G and X2G sections are released in turn. The virtual sections are changed from fault protection to idle in sequence.

[0058] After the train section X3G is released, since there is no fault protection at the rear of the train, the initial fault protection without tail screen will be generated and extended to the station boundary behind the train, that is, X1G, X2G, and X3G become fault protection areas again.

[0059] The tail screen command is issued from CTC to release the train's initial tail screen-free state, and the train completes the tail screen.

[0060] The virtual section idle command is issued from CTC again, and the faulty sections are released in sequence from the station boundary to the train direction, and the X1G and X2G sections are released in turn. The X1G and X2G virtual sections are changed from fault protection to idle in turn.

[0061] After releasing the X3G section where the train is located, the fault protection section will no longer be regenerated.

[0062] Continue to send virtual segment idle commands from CTC to release the fault protection of X4G, and X4G becomes idle.

[0063] Then the CTC issues the first screening command. After the train completes the first screening, it can enter the normal operation mode. The rear train can depart from station 1 to the section in the moving block mode and closely follow the front train.

[0064] Option B:

[0065] The virtual section idle command is issued from CTC, and the faulty sections are released in sequence from the station boundary to the train direction, and the X1G and X2G sections are released in turn. The virtual sections are changed from fault protection to idle in sequence.

[0066] The tail screen command is issued from CTC to release the train's initial tail screen-free state, and the train completes the tail screen.

[0067] The first screening command continues to be issued from CTC and the train completes the first screening.

[0068] The virtual section idle command is continuously issued from CTC to release the fault protection of X4G. After X4G becomes idle, the train can enter the normal operation mode. The rear train can depart from station 1 to the section in the moving block mode and closely follow the front train.

[0069] like Figure 2 As shown, the implementation process of the present invention is described in detail:

[0070] Step 100: The train runs to the virtual section X3G for initial registration.

[0071] Depending on whether the system can clear the faulty section with a vehicle, this solution is divided into two: Solution A (step 101-step 107) and Solution B (step 201-step 204).

[0072] Step 101: In the direction of X1G-X4G, a virtual section idle command is issued sequentially to release the fault protection of the sections X1G and X2G behind the section where the train is located;

[0073] Step 102: After issuing the virtual section idle command of X3G and releasing the fault protection of X3G, the fault protection zone is regenerated at the rear of the train, that is, X1G, X2G, and X3G become the fault protection zone again;

[0074] Step 103: Send a tail screening command to the train, and the train completes the tail screening;

[0075] Step 104: again in the direction of X1G-X4G, the virtual section idle command is issued sequentially to release the fault protection of the sections X1G and X2G behind the section where the train is located;

[0076] Step 105: the virtual section idle command of X3G is issued again. After the X3G fault protection is released, the fault protection zone is no longer generated behind the train, that is, the X1G, X2G, and X3G fault protection zones are released;

[0077] Step 106: Issue a virtual section idle command of X4G to release the fault protection of the section X4G in front of the section where the train is located.

[0078] Step 107: Issue the first screening command to the train, the train completes the first screening and enters the normal operation mode, the rear train can depart from station 1 to the section in the moving block mode and can closely follow the front train. Solution A ends.

[0079] Step 201: In the direction of X1G-X4G, a virtual section idle command is issued sequentially to release the fault protection of the sections X1G and X2G behind the section where the train is located;

[0080] Step 202: Send a tail screening command to the train, and the train completes the tail screening;

[0081] Step 203: Send a first screening command to the train, and the train completes the first screening;

[0082] Step 204: Issue the virtual section idle command of X4G to release the fault protection of the section X4G in front of the section where the train is located. The train enters the normal operation mode, and the rear train can depart from station 1 to the section in the moving block mode and can closely follow the front train. Solution B ends.
