Description

Technical Field

[0001] The invention relates to a train signal control system, and in particular to a design method, equipment and medium for dividing the boundary of a concentrated station for rail transportation equipment. Background Art

[0002] Urban rail transit has the characteristics of large capacity, high speed, safety and punctuality. The signal system is responsible for the operation control of the train, and its system availability and safety directly affect passenger safety and service quality.

[0003] The urban rail transit signal system is mainly composed of the train automatic protection subsystem ATP, the train automatic driving subsystem ATO, the interlocking subsystem CI, the train automatic monitoring subsystem ATS, the maintenance support subsystem MSS, and the data communication subsystem DCS. Among them, the DCS subsystem provides a transmission channel for the information exchange of the signal system; the CI system controls the turnout switch and signal machine on the trackside according to certain procedures and conditions, establishes the train operation route, and ensures the safety interlocking between the track section, turnout, and signal machine on the route. It is a key equipment to ensure the safety of the train operation route. When the DCS backbone network between the equipment centralized stations is unavailable, the forward route to the adjacent station cannot be established, and the train will not be able to operate normally. Only through human intervention, the train operation is organized by telephone blocking. Since the signal cannot be opened, the driver can only rely on the dispatching order to start the train, which is completely dependent on the business capabilities of the dispatcher and timing. The lack of signal equipment will increase the risk of line operation. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a design method, equipment and medium for dividing the boundaries of rail transit equipment centralized stations. When network communication between stations is unavailable, a forward route can be established and the driver can drive according to the display of the signal.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] According to a first aspect of the present invention, a method for designing the boundary division of a rail transit equipment centralized station is provided, the method comprising the following steps:

[0007] Step S1, clearly define the display meaning of the signal light to distinguish different operation scenarios;

[0008] Step S2, setting the equipment concentration station boundary at the route interval signal;

[0009] Step S3, setting the equipment concentration station boundary in the interval;

[0010] Step S4: define the system judgment principle and interlocking processing principle when the inter-station communication is interrupted.

[0011] As a preferred technical solution, the display meaning of the signal light in step S1 is specifically as follows:

[0012] Define the display meaning of signal lights in different scenarios under interlocking mode {L,LU,U,UU,H}.

[0013] As a preferred technical solution, the L light: the section within the route range is idle and the protection section is idle, and the turnout in the route is locked and opened to the straight direction;

[0014] LU lighting: The section within the route range is free, but the protection section is occupied, the switches within the route are locked and open to the straight direction;

[0015] U light: the section within the route range is free and the protection section is free, and the switches within the route are locked and the lateral direction is open;

[0016] UU light: the section within the route range is free, but the protection section is occupied, the switches within the route are locked and the lateral direction is opened;

[0017] H light: No trains allowed to pass.

[0018] As a preferred technical solution, the step S2 is specifically as follows:

[0019] The boundary of the equipment concentration station is set at the approach interval signal to ensure that all sections within the forward train approach range are under the jurisdiction of the same equipment concentration station.

[0020] As a preferred technical solution, the step S2 specifically includes:

[0021] Step S21, case 1, the boundary of the equipment concentration station is set at the route interval signal;

[0022] The route S0501-S0601 from equipment concentration station A to equipment concentration station B, and all sections SDD2 and SDD3 within the route range are under the jurisdiction of equipment concentration station A; when the inter-station communication is interrupted, the system is downgraded to the interlocking backup mode, and the route establishment and signal opening of S0501-S0601 are not affected. The driver controls the normal operation of the train according to the dispatching order and the display of signal S0501;

[0023] Step S22: Case 2: There is no route interval signal at the boundary of the equipment concentration station

[0024] The section SDD2 that needs to be inspected for the route S0501-S0601 from equipment concentration station A to equipment concentration station B is under the jurisdiction of equipment concentration station A, and SDD3 is under the jurisdiction of equipment concentration station B. When the communication between stations is interrupted, the system is downgraded to the interlocking backup mode. Since station A cannot obtain the information of SDD3, the route S0501-S0601 cannot be established, the signal S0501 cannot open the permission signal, and the driver cannot control the normal operation of the train according to the display of the S0501 signal.

[0025] As a preferred technical solution, the step S3 is specifically as follows:

[0026] Step S31, case 1, the boundary of the equipment concentration station is set at the platform;

[0027] Signal S0501 is the exit signal of equipment concentration station A. Its signal opening requires checking the train detention status, platform door status, and emergency stop status information of platform A. When the inter-station communication is interrupted, the system is downgraded to the interlocking backup mode. Since station B cannot obtain the above information, signal S0501 cannot open the permission signal, and the driver cannot control the normal operation of the train according to the display of S0501 signal.

[0028] Step S32, case 2, the boundary of the equipment concentration station is set in the interval;

[0029] Signal S0601 is located in the section and is controlled by the equipment centralized station B. Its signal opening conditions are not affected by the platform detention, platform door status and emergency stop status of the adjacent station A. When the communication between stations is interrupted, the system is downgraded to the interlocking backup mode, the S0601-S0602 route can be established, the signal can be opened, and the train can run normally from station A to station B according to the signal display.

[0030] As a preferred technical solution, the step S4 is specifically as follows:

[0031] Step S41, adding a safety communication status supervision code bit between equipment centralized stations, which is normally 1 and 0 when there is a communication failure between stations;

[0032] Step S42: When the inter-station communication is interrupted, the interlocking detects that the code position is 0, prohibits the arrangement of the reverse route, and ensures the establishment of the forward train route to the adjacent equipment concentration station;

[0033] Step S43: After the forward train route is established, since the status of the protection section cannot be transmitted through the network, the signal of the forward route opens the downgrade signal and displays the LU light;

[0034] Step S44: The driver drives the train to run normally according to the display of the signal, from the centralized station A to the centralized station B.

[0035] As a preferred technical solution, the safety communication status supervision code bits in step S41 are encoded through a safety communication protocol.

[0036] 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.

[0037] 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.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] 1. The present invention relates to a design method for dividing the boundaries of concentrated stations for urban rail transit equipment. The method takes into account the reduction of the impact of network communication interruptions between stations on operations through optimized design without increasing hardware costs.

[0040] 2. The present invention can achieve the establishment of a positive train route and signal opening in the interlocking mode through the optimized design of the signal system when the network between equipment centralized stations is unavailable, and the driver can drive the train to operate normally based on the display of the signal.

[0041] 3. The present invention can ensure the safety of the route by signal equipment when the network between equipment stations is unavailable, which will reduce the risk of human-organized operation.

[0042] 4. The boundary of the equipment concentration station of the present invention is set in the interval, which can ensure that the equipment indoors and outdoors belongs to the same equipment concentration station, reducing the confusion of operators.

[0050] 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.

[0051] like Figure 1 As shown, a design method for dividing the boundary of a concentrated station for urban rail transit equipment includes:

[0052] Step S1, clearly define the display meaning of the signal light to distinguish different operation scenarios;

[0053] Step S2, setting the equipment concentration station boundary at the route interval signal;

[0054] Step S3, setting the equipment concentration station boundary in the interval;

[0055] Step S4: define the system judgment principle and interlocking processing principle when the inter-station communication is interrupted.

[0056] 1. Signal display definition:

[0057] The step S1 is specifically as follows:

[0058] Step S11, define the display meanings of the traffic lights in different scenarios under the interlocking mode {L, LU, U, UU, H}.

[0059] Step S12, L light: the section within the route range is idle and the protection section is idle, and the turnout in the route is locked and opened to the straight direction;

[0060] Step S13, LU lighting: the section within the route range is idle, but the protection section is occupied, the switch in the route is locked and opened to the straight direction;

[0061] Step S14, U light: the section within the route range is idle and the protection section is idle, and the turnout in the route is locked and the lateral direction is opened;

[0062] Step S15, UU lighting: the section within the route range is idle, but the protection section is occupied, the switch within the route is locked and the lateral direction is opened;

[0063] Step S16, H light: prohibit trains from passing.

[0064] 2. The boundary of the equipment concentration station is set at the approach interval signal;

[0065] The step S2 is specifically as follows:

[0066] The boundary of the equipment concentration station is set at the approach interval signal to ensure that all sections within the forward train approach range are under the jurisdiction of the same equipment concentration station.

[0067] Step S21, case 1, the boundary of the equipment concentration station is set at the route interval signal (such as Figure 2 ).

[0068] The route S0501-S0601 from equipment concentration station A to equipment concentration station B, and all sections SDD2 and SDD3 within the route range are under the jurisdiction of equipment concentration station A. When the inter-station communication is interrupted, the system is downgraded to the interlocking backup mode, and the route establishment and signal opening of S0501-S0601 are not affected. The driver can control the normal operation of the train according to the dispatching order and the display of the signal S0501.

[0069] Step S22, case 2, there is no route interval signal at the boundary of the equipment concentration station (such as Figure 3 ).

[0070] The section SDD2 that needs to be checked for the route S0501-S0601 from equipment concentration station A to equipment concentration station B is under the jurisdiction of equipment concentration station A, and SDD3 is under the jurisdiction of equipment concentration station B. When the communication between stations is interrupted, the system is downgraded to the interlocking backup mode. Since station A cannot obtain the information of SDD3, the route S0501-S0601 cannot be established, the signal S0501 cannot open the permission signal, and the driver cannot control the normal operation of the train according to the display of the S0501 signal.

[0071] 3. The boundary of the equipment concentration station is set in the interval;

[0072] The step S3 is specifically as follows:

[0073] Step S31, case 1, the boundary of the equipment concentration station is set at the station (such as Figure 4 ).

[0074] Signal S0501 is the exit signal of equipment concentration station A. Its opening requires checking the information such as the vehicle detention status, platform door status, and emergency stop status of platform A. When the communication between stations is interrupted, the system is downgraded to the interlocking backup mode. Since station B cannot obtain the above information, signal S0501 cannot open the permission signal, and the driver cannot control the normal operation of the train according to the display of signal S0501. At the same time, signal S0501 is the exit signal of equipment concentration station A, and its control belongs to equipment concentration station B. There is a problem of inconsistency between the logical control and physical ownership of the equipment, which is easy to cause confusion for operators.

[0075] Step S32, case 2, the boundary of the equipment concentration station is set in the interval (such as Figure 2 ).

[0076] Signal S0601 is located in the section and is controlled by the equipment centralized station B. Its signal opening conditions are not affected by the platform detention, platform door status and emergency stop status of the adjacent station A. When the inter-station communication is interrupted, the system is downgraded to the interlocking backup mode, the S0601-S0602 route can be established, the signal can be opened, and the train can run normally from station A to station B according to the signal display. At the same time, the logical control of the equipment is consistent with the physical ownership, which is easy for operators to use.

[0077] 4. Define the system judgment principles and interlocking processing principles when inter-station communication is interrupted.

[0078] The step S4 is specifically as follows:

[0079] Step S41: Add a safety communication status monitoring code (Netcom) between stations in the equipment collection. The code is encoded through a safety communication protocol, and is normally 1, and is 0 when there is a communication failure between stations.

[0080] Step S42, when the inter-station communication is interrupted, the interlocking detects that the code position is 0, prohibits the arrangement of the reverse route (S0602-S0601), and ensures the establishment of the forward train route (S0501-S0601) leading to the adjacent equipment concentration station.

[0081] Step S43, after the route S0501-S0601 is established, since the status of the protection section (SDD4) cannot be transmitted through the network, the signal (S0501) of the forward route (S0501-S0601) opens the downgrade signal and displays the LU light (such as Figure 5 ).

[0082] Step S44: The driver drives the train to run normally according to the display of the signal, from the centralized station A to the centralized station B. Specific embodiments

[0084] The method of the present invention comprises the following steps:

[0085] Step 100, the signal system is a mobile block communication-based train automatic control system, including an automatic train control subsystem (ATC), an interlocking subsystem (CI), an automatic train monitoring subsystem (ATS), a maintenance support subsystem (MSS), and a data communication subsystem (DCS); the ATC subsystem is composed of on-board ATC equipment and trackside ATC equipment;

[0086] Step 101, the DCS subsystem provides redundant communication channels for the ATC, ATS, CI, and MSS subsystems;

[0087] Step 102, set the boundary between equipment concentration station A and equipment concentration station B at S0601 signal machine, S0601 is the route interval signal. S0501-S0601 is under the jurisdiction of equipment concentration station A, S0601-S0602 is under the jurisdiction of equipment concentration station B, S0501-S0601 and S0602-S0601 are mutually hostile routes.

[0088] Step 103, setting the boundary between the equipment concentration station A and the equipment concentration station B at the S0601 signal, and S0601 is located in the section.

[0089] Step 104, when the communication between equipment concentration station A and equipment concentration station B is normal (Netcom=1), the protection section SDD4 can be transmitted from station B to station A through inter-station communication. When S0602-S0601 is not established, S0501-S0601 can be established. When SDD4 is idle, S0501 opens the L light position; when SDD4 is occupied, S0501 opens the LU light position.

[0090] Step 105, when the communication between equipment concentration station A and equipment concentration station B is abnormal (Netcom=0), the occupation status of the protection section SDD4 and the establishment status of S0602-S0601 cannot be transmitted from station B to station A through inter-station communication. According to the "fail-safe" principle, equipment concentration station A believes that the hostile approach S0602-S0601 of S0501-S0601 is in the establishment state, then S0501-S0601 cannot be established, the signal cannot be opened, and the driver will not be able to drive according to the signal display.

[0091] Step 106, when the equipment concentration station A / B detects abnormal communication between stations (Netcom=0), the equipment concentration station B prohibits the arrangement of the reverse route, that is, prohibits the arrangement of S0602-S0601; the equipment concentration station A can arrange the forward route, that is, S0501-S0601 can be arranged. Since the status of the protection section SDD4 is unknown, the S0501 signal opens the LU light position, and the driver can drive according to the signal display.
