Description

Technical Field

[0001] This application relates to the field of rail transit control technology, and more specifically, to a cross-interlocking turnout drive control method, storage medium, and electronic equipment based on route status. Background Technology

[0002] Rail transit lines have many stations, and the equipment connecting the up and down lines and storage tracks is called a turnout. Different routes are formed according to the different positions of the turnouts, and these routes are protected by signals. To ensure safety, it is essential to establish a defined interlocking relationship between the signals, routes, and turnouts; this relationship is called interlocking. Computer Interlocking (CI) equipment is typically used to achieve this function, ensuring the safe operation of trains or shunting cars within the station. Currently, how to achieve cross-interlocking turnout actuation is a pressing technical challenge that needs to be solved. Summary of the Invention

[0004] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0005] According to a first aspect of the embodiments of this application, a cross-interlocking turnout drive control method based on route status is provided, including: The first computer interlocking device determines the target route with the first signal as the starting point and the second signal as the ending point according to the route handling order. The first signal is controlled by the first computer interlocking device, and the second signal is controlled by the second computer interlocking device. After the target route is in the "Route Status - Selection" state, the second computer interlocking device drives the turnouts / protective turnouts in its own control area to the position corresponding to the target route, and the first computer interlocking device drives the turnouts / protective turnouts in its own control area to the position corresponding to the target route. The position corresponding to the target route refers to the position that can make the turnout change the track direction. After confirming that all turnouts / protective turnouts within the target route are in their corresponding positions within the target route, lock all turnouts and the target route, and open the first signal.

[0006] In some embodiments of this application, based on the foregoing scheme, after determining the target route, the method further includes: The first computer interlocking device requisitions all sections within the target route.

If there are sections in the target route that are controlled by the second computer interlocking device, the first computer interlocking device sends a section requisition application to the second computer interlocking device. After the second computer interlocking device reports that the section requisition is successful, the target route status is updated to "Route Status - Selected".

[0008] In some embodiments of this application, based on the foregoing scheme, the second computer interlocking device drives the turnouts / protective turnouts within its control area to the corresponding positions, including: The second computer interlocking device polls all switches / protective switches within its control area. If a switch / protective switch within its control area can be turned, it drives the switch / protective switch within its control area to the position corresponding to the target route and sets the switch drive flag to successful.

[0009] In some embodiments of this application, based on the foregoing scheme, the first computer interlocking device drives the turnouts / protective turnouts within its control area to the position corresponding to the target route, including: After the second computer interlocking device successfully drives the turnout, the first computer interlocking device drives the turnout / protective turnout within its control area to the position corresponding to the target route, so that the track where the first computer interlocking device is located is connected to the track where the second computer interlocking device is located.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] The following detailed description of some embodiments of this application will be provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] See Figure 1 The diagram shows a flowchart of a cross-interlocking turnout drive control method based on route status according to an embodiment of this application.

[0023] like Figure 1 As shown, a cross-interlocking turnout drive control method based on route status is illustrated, specifically including steps S100 to S300.

[0024] refer to Figure 1 In step S100, the first computer interlocking device determines the target route with the first signal as the starting point and the second signal as the ending point according to the route handling command. The first signal is controlled by the first computer interlocking device, and the second signal is controlled by the second computer interlocking device.

[0025] For example, such as Figure 2 As shown, the ATS (Automatic Train Control System) issues a route management instruction to the first computer interlocking device to manage the target route F1-Z1, which starts with signal F1 and ends with signal Z1.

[0026] exist Figure 2In this system, signals F1 and Z2 are controlled by the first computer interlocking device CI1, while signals F2 and Z1 are controlled by the second computer interlocking device.

[0027] Continue to refer to Figure 1 In step S200, after the target route is in the "route state - selection" state, the second computer interlocking device drives the turnouts / protective turnouts in its own control area to the position corresponding to the target route, and the first computer interlocking device drives the turnouts / protective turnouts in its own control area to the position corresponding to the target route. The position corresponding to the target route refers to the position that can make the turnout change the track direction.

[0028] In some feasible embodiments, based on the foregoing scheme, after determining the target route, the method further includes: The first computer interlocking device requisitions all sections within the target route. After successfully requisitioning all sections, it updates the status of the target route to "Route Status - Selection".

[0029] It should be noted that a route refers to the path a train or shunting train takes within a station, while route selection refers to an instruction requiring the selection of routes and the arrangement of corresponding route sequences. For example, in a railway station, when a train needs to enter the station or a shunting operation is to be carried out, the signaling system selects and arranges routes according to relevant rules and operator instructions.

[0030] In some feasible embodiments, based on the foregoing scheme, the first computer interlocking device requisitions all sections within the target route. After all sections are successfully requisitioned, the status of the target route is updated to "Route Status - Selection," including: After checking that the interlocking conditions for the route are met, the first computer interlocking device requisitions all sections within the target route. If there are sections in the target route that are controlled by the second computer interlocking device, the first computer interlocking device sends a section requisition application to the second computer interlocking device. After the second computer interlocking device reports that the section requisition is successful, the target route status is updated to "Route Status - Selected".

[0031] In some feasible embodiments, based on the foregoing scheme, the second computer interlocking device drives the turnouts / protective turnouts within its control area to the corresponding positions, including: The second computer interlocking device polls all switches / protective switches within its control area. If a switch / protective switch within its control area can be turned, it drives the switch / protective switch within its control area to the position corresponding to the target route and sets the switch drive flag to successful.

[0032] For example, refer to Figure 2Turnout 1 and turnout 5 are controlled by the second computer interlocking device. After the target route is in "route status - selection", the second computer interlocking device drives turnout 5 to the reverse position and turnout 1 to the position.

[0033] It should be noted that while the computer interlocking equipment drives the turnouts, it also needs to manage the turnout drive flags for the route. The turnout drive flags for the route have three states: "Default," "Failure," and "Success." In the default state, the computer interlocking equipment does not execute turnout drive to prevent a scenario where only the local interlocking (the computer interlocking equipment where the starting signal is located) activates the turnout, while the other interlocking (the computer interlocking equipment where the ending signal is located) does not activate, ultimately resulting in a turnout rotation failure. "Failure" indicates a turnout rotation failure; in this state, the route application has failed and needs to be re-application after troubleshooting. "Success" indicates a state that occurs during turnout rotation or after the turnout has reached its position, signifying that the route application is in progress or has been successfully completed.

[0034] In some feasible embodiments, based on the foregoing scheme, the first computer interlocking device drives the turnouts / protective turnouts within its control area to the position corresponding to the target route, including: After the second computer interlocking device successfully drives the turnout, the first computer interlocking device drives the turnout / protective turnout within its control area to the position corresponding to the target route, so that the track where the first computer interlocking device is located is connected to the track where the second computer interlocking device is located.

[0035] For example, refer to Figure 2 Turnouts 7 and 9 are controlled by the first computer interlocking device. After the second computer interlocking device successfully drives the turnouts, it will send a "success" turnout drive flag to the first computer interlocking device. After receiving the "success" turnout drive flag, the first computer interlocking device will drive turnout 7 to the reverse position and turnout 9 to the position.

[0036] Continue to refer to Figure 1 In step S300, after determining that all the switches / protective switches in the target route are in their corresponding positions in the target route, all switches and the target route are locked, and the first signal is opened.

[0037] For example, see Figure 3 ,like Figure 3 As shown, after the first computer interlocking device detects that turnout 7 is in the reverse position and turnout 9 is in the position, and the second computer interlocking device detects that turnout 5 is in the reverse position and turnout 1 is in the position, the first computer interlocking device executes the route locking command, locking both the turnouts and the route, and simultaneously driving the starting signal F1 to open.

[0038] In summary, the method provided in this application solves the faults of real-time synchronization of turnout drive and turnout position drive between interlocking systems, realizes turnout drive across interlocking systems, and optimizes the design principles of the station yard and the division principles of the interlocking centralized area.

When the processor 420 executes the computer program 411, it implements the steps of the above-mentioned method for cross-interlocking turnout drive control based on route status.
