Description

Technical Field

[0001] This invention belongs to the field of rail transit technology, specifically relating to a method for compatibility between resource routes and interlocking routes. Background Technology

[0002] The CBTC (Combined Train Control) area for train-to-train communication employs resource management for route management. The proposed resource-based train safety route method effectively improves train operating efficiency in switch areas and operational flexibility within sections. However, when train communication fails or when building a train-to-train communication system on top of an existing interlocking system, there are shortcomings such as the inability to achieve hostile protection and intrusion protection between resource routes and interlocking routes. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a compatible method and system for resource routes and interlocking routes, so as to achieve adversarial protection and intrusion protection between resource routes and interlocking routes when train communication fails or when a train-to-train communication system is built on top of an existing interlocking system.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] First, a compatible system for resource routes and interlocking routes is provided, including an ATS, a resource module, and an interlocking module; the resource module receives route commands from the ATS and resource instructions from the vehicle controller, and outputs commands to the interlocking module according to the route commands from the ATS and the resource instructions from the vehicle controller.

[0006] The resource module is equipped with a resource mutual exclusion occupancy judgment module, which is used to judge whether the corresponding turnout or side defense resource inside the resource module is in a hostile occupancy state; if it is not in a hostile occupancy state, the turnout and side defense resource are occupied.

[0007] According to the resource instructions from the vehicle controller, after the switch resource is occupied, the resource module outputs a switch locking command to the interlocking module, and the interlocking module locks the switch.

[0008] After acquiring train resources and occupying turnout and side protection resources according to the route command of ATS, the resource module outputs a route locking command to the interlocking module, which then locks the route.

[0009] Secondly, a method for compatibility between resource routes and interlocking routes is provided, including:

[0010] The resource module receives the route command from the ATS and the resource instructions from the on-board controller, and outputs commands to the interlocking module according to the route command from the ATS and the resource instructions from the on-board controller.

[0011] The resource module determines whether the corresponding turnout or side defense resource is in a hostile occupation state; if it is not in a hostile occupation state, it occupies the turnout and side defense resource.

[0012] After the resource module completes the occupation of the turnout resources according to the resource instructions of the vehicle controller, the resource module outputs a turnout locking command to the interlocking module, and the interlocking module completes the locking of the turnout.

[0013] After the resource module completes the acquisition of train resources and the occupation of turnout and side protection resources according to the route command of ATS, the resource module outputs the route locking command to the interlocking module, and the interlocking module completes the locking of the route.

[0014] Preferably, the resource module outputs a route locking command to the interlocking module according to the route command of the ATS, and releases the resources of that section after the interlocking module unlocks a certain section.

[0015] Preferably, the resource module outputs turnout locking and turnout unlocking commands to the interlocking module according to the resource occupancy and resource release commands from the vehicle controller.

[0016] Preferably, after receiving the ATS route command, the resource module acquires the required train resources and occupies the turnout resources and side protection resources according to the route command, wherein the train resources are acquired through interaction with the on-board controller.

[0017] Preferably, when a section inside the route is unlocked, the interlocking module sends the section unlocking information to the resource module; after obtaining the section unlocking information, the resource module releases the corresponding train resources for that section and cancels the occupation of turnouts and side protection resources.

[0018] Preferably, if the side defense resource involves multiple sections, the side defense resource occupation shall be cancelled after all sections involved in the side defense resource are unlocked.

[0019] Preferably, after the resource module completes the occupation of the turnout resource according to the command of the vehicle controller and the turnout is in the desired position of the vehicle controller, it outputs a turnout locking command to the interlocking module.

[0020] Once the turnout is locked, the resource controller sends a turnout clearance message to the onboard controller.

[0021] After the train passes the turnout, it sends a command to the resource module to cancel the turnout occupation. The resource module then releases the turnout resource and sends a turnout unlock command to the interlocking module.

[0022] Additionally, an electronic device is also provided, the electronic device comprising:

[0023] The memory stores multiple instructions;

[0024] A processor that loads instructions from the memory to execute the steps in the compatibility method.

[0025] And a computer-readable storage medium having a computer program stored thereon that, when executed by an electronic device, implements the steps in the compatibility method described above.

[0026] The technical solution adopted in this invention has the following beneficial effects:

[0027] 1. Adding a resource module on top of the existing interlocking module is suitable for building a downgraded operation system for the train-to-train communication system, or for building a resource-based train-to-train communication system while retaining the existing interlocking-based safety system, so as to realize the mixed operation of trains with two different protection principles and achieve a seamless upgrade from the interlocking-based train safety protection system to the resource-based train-to-train communication system.

[0028] 2. Simultaneously equipped with resource and interlocking modules, it allows interlocking routes and resource routes to coexist in the operating system, enabling trains operating safely using interlocking routes and those operating safely using resource routes to run together. Furthermore, through the mutual exclusion of train resources, turnout resources, and side protection resources, it achieves the safe separation of trains operating safely using trackside signals controlled by interlocking routes and trains operating safely using resource protection, avoiding risks such as rear-end collisions, head-on collisions, and side collisions.

[0029] The specific technical solution of the present invention and its beneficial effects will be described in detail in the following specific embodiments in conjunction with the accompanying drawings. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] Figure 1 This is a schematic diagram illustrating the principle of a compatible system for resource routes and interlocking routes according to the present invention. Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention proposes a method for the compatible coexistence of resource-based routes and interlocking routes, enabling trains operating safely using interlocking routes and those operating safely using resource-based routes to run in a mixed manner. This is applicable to both building a degraded operation system for the vehicle-to-vehicle communication system and simultaneously establishing a resource-based vehicle-to-vehicle communication system while retaining an existing interlocking-based safety system, achieving mixed operation of trains with two different protection principles and enabling a seamless upgrade from an interlocking-based train safety protection system to a resource-based vehicle-to-vehicle communication system.

[0034] Example 1

[0035] like Figure 1 As shown, a compatible system for resource routes and interlocking routes includes an ATS, a resource module, and an interlocking module; the resource module receives route commands from the ATS and resource instructions from the vehicle controller, and outputs commands to the interlocking module according to the route commands from the ATS and the resource instructions from the vehicle controller.

[0036] The resource module is equipped with a resource mutual exclusion occupancy judgment module, which is used to determine whether the corresponding turnout or side protection resource within the resource module is in a hostile occupancy state. If it is not in a hostile occupancy state, the turnout and side protection resource are occupied. After the turnout resource is occupied according to the resource instructions of the vehicle controller, the resource module outputs a turnout locking command to the interlocking module, and the interlocking module completes the locking of the turnout. After the train operation resource is acquired and the turnout and side protection resource are occupied according to the route command of the ATS, the resource module outputs a route locking command to the interlocking module, and the interlocking module completes the locking of the route.

[0037] The above technical solution adds a resource module to the existing interlocking module. The resource module obtains and allocates driving resources through interaction with the onboard system. Because both the resource module and the interlocking module are present, interlocking routes and resource routes can coexist in the operating system, allowing trains operating safely using interlocking routes and trains operating safely using resource routes to run in a mixed configuration.

[0038] Furthermore, by mutually exclusive use of train resources, turnout resources, and side protection resources, the safe separation of trains operating safely based on trackside signals under interlocking route control and trains operating safely based on resource protection is achieved, thus avoiding risks such as rear-end collisions, head-on collisions, and side collisions.

[0039] In the above technical solution, the resource module is responsible for receiving route commands from the ATS and interacting with the onboard controller. Based on the route commands from the ATS, the resource module acquires and occupies resources, and then outputs a route locking command to the interlocking module. After the interlocking module unlocks a certain section, it releases the resources for that section. Based on the resource occupancy instructions from the onboard controller, the resource module outputs a turnout locking command to the interlocking module, and upon receiving a resource release instruction from the onboard controller, it outputs a turnout unlocking command to the interlocking module.

[0040] It is understandable that the resource module and the interlocking module can be used as independent controllers, or they can be two relatively independent functional modules within the same controller.

[0041] Example 2

[0042] A method for achieving compatibility between resource routes and interlocking routes, employing a compatibility system for resource routes and interlocking routes as described in Embodiment 1, includes:

[0043] The resource module receives the route command from the ATS and the resource instructions from the on-board controller, and outputs commands to the interlocking module according to the route command from the ATS and the resource instructions from the on-board controller.

[0044] The resource module determines whether the corresponding turnout or side defense resource is in a hostile occupation state; if it is not in a hostile occupation state, it occupies the turnout and side defense resource.

[0045] According to the resource instructions from the vehicle controller, after the switch resource is occupied, the resource module outputs a switch locking command to the interlocking module, and the interlocking module locks the switch.

[0046] After acquiring train resources and occupying turnout and side protection resources according to the route command of ATS, the resource module outputs a route locking command to the interlocking module, which then locks the route.

[0047] The detailed process is explained below:

[0048] When the resource module receives the ATS route command, it acquires the necessary train operation resources and occupies turnout and side protection resources according to the route command. Train operation resources are acquired through interaction with the onboard controller. The acquisition of turnout and side protection resources is determined by checking whether the corresponding turnout or side protection resource within the resource module is in a hostile occupation state. If it is not in a hostile occupation state, the turnout and side protection resource are occupied. After acquiring train operation resources and occupying turnout and side protection resources, the resource module outputs a route locking command to the interlocking module, which then locks the route. After the train passes through the route, the interlocking system performs segmented unlocking or one-time unlocking. When a section within the route is unlocked, the interlocking system sends the section unlocking information to the resource module. After receiving the section unlocking information, the resource module unlocks the corresponding train operation resources for that section and cancels the occupation of turnout and side protection resources. If a side protection resource involves multiple sections, all sections involved in the resource must be unlocked before the resource occupation can be canceled.

[0049] When the resource module receives a command from the onboard controller to occupy the turnout and side protection resources, it checks whether the turnout and its corresponding internal turnout or side protection resource are in a hostile occupation state. If not, it occupies the turnout and side protection resource. Once the resource module has completed the turnout occupation according to the onboard controller's command and the turnout is in the position desired by the onboard controller, it outputs a turnout locking command to the interlocking module. After the turnout locking is completed, the resource controller sends a turnout passage permission message to the onboard controller. After the train passes the turnout, it outputs a command to cancel the turnout and side protection resource occupation to the resource module. The resource module then releases the turnout and side protection resource occupation and outputs a turnout unlocking command to the interlocking module.
