Description

Technical Field

[0001] This invention belongs to the technical field of rail transit signaling systems, and particularly relates to a resource management method compatible with TACS and CBTC systems. Background Technology

[0002] In the development of rail transit signaling systems, the traditional CBTC (Communication-Based Train Control) system adds route attributes to achieve unified management of CBTC and non-CBTC train routes, thus enabling mixed operation of CBTC and faulty trains. The TACS (Train Autonomous Operation System) system replaces the traditional route management method with resource management, achieving more efficient train operation. However, the TACS system is difficult to be compatible with the traditional CBTC system based on route management. During the upgrading of old lines from the traditional CBTC system to the TACS system, there is a phase where TACS trains and CBTC trains run together. Simultaneously, to meet the unified management requirements of downgraded modes (including point-to-point and pure backup interlocking modes), the TACS system also needs to simultaneously enable mixed operation of point-to-point trains and faulty trains.

[0003] In the prior art, Chinese invention patent CN115366954B provides a system and method for TACS and CBTC to operate compatibly. This is achieved by connecting the TACS and CBTC systems through devices such as a TACS trackside resource manager and a CBTC trackside area controller. However, this patent does not provide a feasible resource management method, and it remains unknown whether the compatible system can simultaneously accommodate the mixed operation of spot-track trains and faulty trains.

[0004] Therefore, how to provide a practical and feasible resource management method compatible with both TACS and CBTC systems is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a resource management method compatible with both TACS and CBTC systems. The TACS system can implement the functions of the CBTC system through different resource packages, achieving compatibility between the two systems and enabling mixed operation of TACS and CBTC trains.

[0006] This invention provides a resource management method compatible with both TACS and CBTC systems, comprising:

[0007] Resource packages are formed by using the logical relationships between the same or different resources. Each resource package has a unique ID. Resources are applied for in the form of resource packages to realize the system functions corresponding to the resource packages.

[0008] The resource package includes static resource packages and dynamic resource packages. Static resource packages are a collection of resources allocated during the system design and data preparation phase based on the resource allocation of the line and the functional requirements of the system. Dynamic resource packages are a collection of resources allocated in real time during the train operation phase based on the needs of system operation and management.

[0009] In this technical solution, the TACS system can realize the functions of the CBTC system through different resource packages, achieving compatibility between the two systems and enabling TACS trains and CBTC trains to run together.

[0010] In some embodiments, the static resource package includes an SPKS resource package for implementing the SPKS personnel protection switch function, and track section resource packages, physical section resource packages, off-route shunting resource packages, train route resource packages, and shunting route resource packages for compatibility with the CBTC system.

[0011] Among them, the track section resource package is used to be compatible with track section equipment in the CBTC system, the physical section resource package is used to be compatible with physical section equipment in the CBTC system, the off-route shunting resource package is used to be compatible with off-route shunting functions in the CBTC system, the train route resource package is used to be compatible with train routes in the CBTC system, and the shunting route resource package is used to be compatible with shunting routes in the CBTC system.

[0012] In some embodiments, the method for allocating each static resource package includes:

[0013] A series of consecutive logical segments, and logical segments that constitute an encroachment relationship with these logical segments, are combined to form an SPKS resource package.

[0014] All switches, switch locations, and logical segments connected end to end in a track section are combined to form a track section resource package. Each track section resource package corresponds to a track section in the CBTC system.

[0015] All switches in the physical section and the logical sections connected end to end are combined to form a physical section resource package. Each physical section resource package corresponds to a physical section in the CBTC system.

[0016] All logic sections, switches, shunting signals, and I / O devices of the non-route shunting connection circuit within the non-route shunting area are combined to form a non-route shunting resource package.

[0017] The signals, switches, and logic sections in the main train route and the protective train route are combined to form a train route resource package;

[0018] The signals, switches, and logic sections in a shunting route are combined to form a shunting route resource package.

[0019] In some embodiments, the train route resource package also includes connecting ports, platform screen doors, and emergency closing buttons in the main train route and the train protection route; the shunting route resource package also includes connecting ports and depot doors in the shunting route. The train route resource package enables the management of route and transponder messages for point-to-point trains, allowing for the mixed operation of TACS trains and point-to-point trains.

[0020] In some embodiments, dynamic resource packages include faulty train rescue resource packages, arbitrary point turnaround resource packages, temporary speed limit resource packages, and area blockade resource packages;

[0021] The package includes three resource packs: a train malfunction rescue resource pack for rescuing malfunctioning trains, a train turnaround resource pack for turning around at any point, a temporary speed limit resource pack for temporarily limiting train speed, and a regional closure resource pack for implementing regional closures. These resource packs enable train malfunction rescue and allow for the mixed operation of TACS trains and malfunctioning trains.

[0022] In some embodiments, the method for allocating train rescue resource packages includes:

[0023] The allocation initiated by ATS combines a series of sequentially arranged logical segments and all associated resources of the logical segments to form a faulty train rescue resource package; the first or several logical segments are the safety envelope of the faulty train's location, and the last logical segment is the platform area or other predefined train parking or maintenance point.

[0024] The allocation methods for resource packages that allow arbitrary point turnaround include:

[0025] The allocation is initiated by the OBC, which combines a series of sequentially arranged logical segments and all the associated resources of the logical segments to form an arbitrary point turnaround resource package; the first or several logical segments are the safety envelope of the location of the faulty train, and the last logical segment is the platform area or other predefined train parking point or maintenance point.

[0026] The allocation methods for temporary rate-limited resource packages include:

[0027] The allocation is initiated by the ATS and executed by the OC and OBC of the control area. A series of sequentially arranged logical segments and speed limit values ​​are combined to form a temporary speed limit resource package.

[0028] The methods for allocating area blockade resource packages include:

[0029] The allocation is initiated by the ATS and executed by the OC and OBC of the control area. A series of continuous logical sections and auxiliary resources such as switches, signals, platform screen doors, emergency closing buttons, and depot doors are combined to form a regional blockade resource package.

[0030] In some embodiments, the resource management method compatible with TACS and CBTC systems further includes the step of combining resource packages to form a resource package. The resource package includes a long shunting route resource package and a long train route resource package. The long shunting route resource package is used for long shunting routes in the depot, and the long train route resource package is used for unified management of several train routes that are connected end to end.

[0031] In some embodiments, the method for allocating long shunting route resource packages includes:

[0032] The allocation is initiated by the ATS when handling long shunting routes, and the shunting route resource packages arranged in sequence and connected end to end are combined to form a long shunting route resource package.

[0033] The allocation method for long-distance train route resource packages includes:

[0034] In depots without shunting signals, the ATS initiates allocation, combining several sequentially arranged train route resource packages end-to-end to form a long train route resource package, used for train track switching operations within the depot. On the main line, the ATS or onboard OBC initiates allocation, combining several sequentially arranged train route resource packages end-to-end and matching them with the train's operating line for unified management of train operation tasks and routes.

[0035] Based on the above solution, the resource management method compatible with TACS and CBTC systems in this embodiment of the invention can achieve mixed operation of TACS trains, CBTC trains, spot trains and faulty trains through the allocation of static resource packages and dynamic resource packages. This enables the TACS system to be used for the construction of any existing line renovation and extension project, realizing flexible switching between old and new systems. That is, there is no need to shut down the operating line when replacing the system, thereby greatly reducing the impact of project implementation on the operation of existing lines and achieving a smooth transition. Detailed Implementation

[0036] The technical solutions in the embodiments are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0038] The terms “system,” “unit,” and “module” used in this article are methods for distinguishing different components, elements, parts, sections, or assemblies at different levels. These terms may be replaced by other expressions that achieve the same purpose.

[0039] In this invention, "resources" refer to lines, signaling equipment, connection ports, and external device interfaces that meet the control and protection logic requirements of the TACS signaling system. Resources are divided into operating resources and auxiliary resources. Operating resources are the smallest unit of TACS system processing logic; a section of operating resources constitutes a logical segment. The granularity of logical segment division is based on meeting the processing requirements of each TACS subsystem, not on physical form. For example, a standard configuration for operating lines is 25 meters of operating resources per logical segment; this can be appropriately shortened at turnouts and lengthened at long straight sections. Auxiliary resources refer to signaling equipment, connection ports, and external device interfaces; each auxiliary resource necessarily belongs to one or more operating resources.

[0040] In one embodiment of the resource management method of the present invention, which is compatible with both TACS and CBTC systems, the method includes:

[0041] Resource packages are formed by using the logical relationships between the same or different resources. Each resource package has a unique ID. Resources are applied for in the form of resource packages to realize the system functions corresponding to the resource packages.

[0042] The resource package includes static resource packages and dynamic resource packages. Static resource packages are a collection of resources allocated during the system design and data preparation phase based on the resource allocation of the line and the functional requirements of the system. Dynamic resource packages are a collection of resources allocated in real time during the train operation phase based on the needs of system operation and management.

[0043] In the above illustrative embodiments, the resource management method compatible with both the TACS and CBTC systems enables simultaneous application for multiple resources by creating resource packages. Each resource package has a unique ID, ensuring that it has a unique function and preventing confusion during resource application. The TACS system can achieve the functions of the CBTC system through different resource packages, thus achieving compatibility between the two systems and enabling the mixed operation of TACS and CBTC trains.

[0044] It should be noted that static resource packages cannot be changed during the actual operation of the system, and the ID of a static resource package is unique and fixed; dynamic resource packages are resource packages that are dynamically generated in real time by OBC, OC or ATS during system operation. They are mainly used to meet the functional requirements of special scenarios. Once the function is completed, the resource package will also be deleted. Dynamic resource packages have dynamically assigned IDs, and the IDs of dynamic resource packages have sufficient value space to ensure that they are not reused.

[0045] In some embodiments, the static resource package includes an SPKS resource package for implementing the SPKS personnel protection switch function, and track section resource packages, physical section resource packages, off-route shunting resource packages, train route resource packages, and shunting route resource packages for compatibility with the CBTC system. Specifically, the track section resource package is for compatibility with track section equipment in the CBTC system, the physical section resource package is for compatibility with physical section equipment in the CBTC system, the off-route shunting resource package is for compatibility with off-route shunting functions in the CBTC system, the train route resource package is for compatibility with train routes in the CBTC system, and the shunting route resource package is for compatibility with shunting routes in the CBTC system. Through different static resource packages, the TACS system can implement the functions of the CBTC system, enabling mixed operation of TACS trains and CBTC trains.

[0046] Furthermore, the allocation methods for each static resource package include:

[0047] A series of consecutive logical segments, and logical segments that constitute an encroachment relationship with these logical segments, are combined to form an SPKS resource package.

[0048] All switches, switch locations, and logical segments connected end to end in a track section are combined to form a track section resource package. Each track section resource package corresponds to a track section in the CBTC system.

[0049] All switches in the physical section and the logical sections connected end to end are combined to form a physical section resource package. Each physical section resource package corresponds to a physical section in the CBTC system.

[0050] All logic sections, switches, shunting signals, and I / O devices of the non-route shunting connection circuit within the non-route shunting area are combined to form a non-route shunting resource package.

[0051] The signals, switches, and logic sections in the main train route and the protective train route are combined to form a train route resource package;

[0052] The signals, switches, and logic sections in a shunting route are combined to form a shunting route resource package.

[0053] In some embodiments, the train route resource package also includes connecting points, platform screen doors, and emergency closing buttons in the main train route and the train protection route; the shunting route resource package also includes connecting points and depot doors in the shunting route. The train route resource package enables route and transponder message management for point-to-point trains, allowing for mixed operation of TACS trains and point-to-point trains.

[0054] In some embodiments, the dynamic resource package includes a train malfunction rescue resource package, an arbitrary point turnaround resource package, a temporary speed limit resource package, and a regional blockade resource package. The train malfunction rescue resource package is used for rescuing malfunctioning trains, the arbitrary point turnaround resource package is used for allowing trains to turn around at any point, the temporary speed limit resource package is used for temporarily limiting train speed, and the regional blockade resource package is used for implementing regional blockades. The train malfunction rescue resource package enables the train malfunction rescue function and allows for the mixed operation of TACS trains and malfunctioning trains.

[0055] In some embodiments, the method for allocating a train rescue resource package includes:

[0056] The ATS initiates the allocation process, combining a series of sequentially arranged logical segments and their associated resources to form a train rescue resource package. The first or several logical segments constitute the safety envelope of the train's location (which can be a communication car or a non-communication car), and the last logical segment is the platform area or other predefined train parking or maintenance point. After the ATS initiates the allocation of the train rescue resource package, it requests all resources within the package for the corresponding train. Once all resources are available, the train rescue operation is executed.

[0057] The allocation methods for resource packages that allow arbitrary point turnaround include:

[0058] The OBC initiates the allocation, combining a series of sequentially arranged logical segments and their associated resources to form an arbitrary point turnaround resource package. The first or several logical segments constitute the safety envelope of the location of the faulty train (which can be a communication car or a non-communication car), and the last logical segment is the platform area or other predefined train parking or maintenance point. After the onboard OBC initiates the allocation of this arbitrary point turnaround resource package, it requests all the resources within the package for itself. Once all resources are in place, the arbitrary point turnaround operation is executed.

[0059] The allocation methods for temporary rate-limited resource packages include:

[0060] The allocation is initiated by the ATS and executed by the OC and OBC of the control area. A series of sequentially arranged logical segments and speed limit values ​​are combined to form a temporary speed limit resource package.

[0061] The methods for allocating area blockade resource packages include:

[0062] The allocation is initiated by the ATS and executed by the OC and OBC of the corresponding control area. A series of consecutive logical sections, along with auxiliary resources such as switches, signals, platform screen doors, emergency stop buttons, and depot doors, are combined to form a regional blockade resource package. When the ATS generates a regional blockade command, it initiates the allocation of a regional blockade resource package. After all resources are requested and in place, the relevant information is sent to the OC and OBC of the corresponding control area, enabling the blockade operation on all resources within the regional blockade resource package.

[0063] It should be noted that the requirement for arbitrary point turnaround has always existed, but traditional CBTC systems and existing TACS systems are difficult to implement in a true arbitrary point turnaround manner. However, true arbitrary point turnaround can be achieved through dynamic resource packages. The above suitable embodiments only provide examples of commonly used static and dynamic resource packages. Other types of resource packages can be created according to other functional design requirements.

[0064] In summary, the resource management method compatible with both TACS and CBTC systems provided in this application enables the mixed operation of TACS trains, CBTC trains, spot-type trains, and faulty trains through the allocation of static and dynamic resource packages. This allows the TACS system to be used for the construction of any existing line renovation and extension project, achieving flexible switching between old and new systems. That is, the line does not need to be shut down when replacing the system, thereby greatly reducing the impact of project implementation on the operation of existing lines and achieving a smooth transition.

[0065] In some embodiments, the resource management method compatible with both TACS and CBTC systems further includes the step of combining resource packages to form resource package packages. These resource package packages include long shunting route resource package packages and long train route resource package packages. The long shunting route resource package package is used for long shunting routes in the depot, while the long train route resource package package is used for unified management of several consecutive train routes. By creating resource package packages, compatibility with the route function in the CBTC system is achieved, while simultaneously improving the efficiency of route management.

[0066] In some embodiments, the method for allocating long-shunting car route resource packages includes:

[0067] The allocation is initiated by the ATS when handling long shunting routes, and the shunting route resource packages arranged in sequence and connected end to end are combined to form a long shunting route resource package.

[0068] The allocation method for long-distance train route resource packages includes:

[0069] In depots without shunting signals, the ATS initiates allocation, combining several sequentially arranged train route resource packages end-to-end to form a long train route resource package, used for train track switching operations within the depot. On the main line, the ATS or onboard OBC initiates allocation, combining several sequentially arranged train route resource packages end-to-end and matching them with the train's operating line for unified management of train operation tasks and routes.
