Description

Technical Field

[0001] This invention relates to the field of urban rail transit technology, and in particular to an urban rail safety management platform and system. Background Technology

[0002] In urban rail transit operation scenarios, train operation control relies on the Communication Based Train Control (CBTC) system to achieve safe scheduling. This system must meet the core requirements of high-density train departures, real-time signal transmission, and multi-subsystem collaboration, and is the key to ensuring the efficiency and safety of urban rail operation.

[0003] In existing technologies, CBTC train control systems generally adopt a three-tier architecture of center, station, and trackside. The ground safety system platform is mostly an embedded dedicated safety computer, and the various subsystems interact through customized communication protocols. Meanwhile, although some cloud-based management platforms can realize operational data storage and basic service management, they mainly focus on data fusion and business support. The former ensures signal security through hardware circuits, while the latter improves operational scientificity through data centers, thus meeting the needs of train control safety and operational management respectively.

[0004] However, the existing solutions have significant drawbacks: the three-tier architecture has tight subsystem dependencies and complex protocols, which leads to reduced system real-time performance and availability; the embedded platforms have different specifications and spare parts vary greatly, resulting in high maintenance workload and personnel requirements, high management difficulty, and limited system capacity and performance expansion. Upgrades and modifications require the linkage of multiple subsystems, making engineering implementation complex. Summary of the Invention

[0005] This invention provides an urban rail safety management platform and system to solve the problems of complex architecture, diverse and difficult-to-maintain hardware, and difficult expansion and upgrade of urban rail CBTC train control system. It can simplify the system, reduce costs and improve efficiency, and ensure operational safety and business continuity.

[0006] This invention provides an urban rail transit safety management platform, characterized by being built using general-purpose computer hardware, comprising: a user interface layer, an application service layer, and a virtualization interface layer; the user interface layer provides a human-computer interaction interface for users; the application service layer receives and parses user instructions transmitted by the user interface layer; executes business logic operations; handles virtual machine management, image library maintenance, fault analysis and alarms, and data storage management; and feeds back the processing results to the user interface layer; the virtualization interface layer provides virtualization interfaces for underlying hardware devices and virtualization resources.

[0007] According to the present invention, a safety management platform for urban rail transit includes a user interface layer comprising a portal interface, a resource management interface, a mirror library interface, a monitoring and alarm interface, a data query interface, a system configuration interface, and a help center interface.

[0008] According to the present invention, an urban rail transit safety management platform includes an application service layer comprising a virtual machine management module, a logic operation module, a fault and alarm module, a data storage module, and a mirror library management module.

[0009] According to the urban rail transit safety management platform provided by the present invention, the virtual machine management module is used to realize the full life cycle management and hot migration of virtual machines.

[0010] According to the urban rail safety management platform provided by the present invention, the logic operation module is used to perform core logic operations of urban rail train control; generate train operation scheduling instructions and signal control strategies; process field data fed back by trackside terminals; and output control instructions and send them to relevant execution units.

[0011] According to the urban rail safety management platform provided by the present invention, the fault and alarm module is used to monitor the virtual machine status and resource usage in real time, and trigger an alarm when an anomaly is confirmed.

[0012] According to the urban rail safety management platform provided by the present invention, the data storage module is used to store train operation data, virtual machine status data, alarm records, and operation logs.

[0013] According to the urban rail safety management platform provided by the present invention, the user interface layer is further used to display the monitoring information and the alarm information based on user query instructions.

[0014] According to the urban rail transit safety management platform provided by the present invention, the image library management module is used for uploading, verifying, version management, permission control and deletion of system images, and maintaining the association configuration between images and virtual machines.

[0015] The present invention also provides an urban rail safety management platform system, comprising: an urban rail safety management platform and a trackside terminal; the urban rail safety management platform is communicatively connected to the trackside terminal through a network interface; the trackside terminal is used to receive and execute control commands issued by the safety cloud platform, collect on-site operation data, and feed it back to the safety cloud platform.

[0016] The urban rail safety management platform and system provided by this invention achieve hardware platform unification by connecting the underlying resources built on general-purpose computer hardware to the underlying hardware devices and virtualization resources through a virtualization interface layer. This reduces maintenance difficulties caused by equipment differences and lowers the professional skill requirements for maintenance personnel. Simultaneously, it avoids compatibility issues between different hardware platforms, providing flexible support for system capacity expansion and performance upgrades without requiring the modification of multiple subsystems, thus reducing engineering implementation complexity. Since the application service layer centrally handles core business logic operations such as virtual machine management, image library maintenance, fault analysis and alarms, and data storage management, replacing the multi-node operation mode scattered across the center, stations, and trackside in the traditional three-layer architecture, it reduces dependencies and complex protocol interactions between subsystems, shortens instruction transmission and data processing paths, and improves system real-time performance and availability. Furthermore, centralized business logic processing optimizes resource scheduling efficiency, further enhancing the overall computing performance of the platform. Since the user interface layer provides a unified human-computer interaction entry point, and the application service layer centrally feeds back the processing results to the interface layer, the platform operation, monitoring, and management functions are integrated. Users can complete resource configuration, fault handling, and other operations through a single entry point, which simplifies the operation process and improves management efficiency.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This application describes some exemplary embodiments for illustrative purposes. It should be understood that this application may be implemented in other ways not specifically shown in the accompanying drawings.

[0023] like Figure 1 As shown in the figure, this application provides an urban rail safety management platform, which is built using general-purpose computer hardware and includes: a user interface layer, an application service layer, and a virtualization interface layer.

[0024] The user interface layer is used to provide users with an entry point for human-computer interaction.

[0025] Specifically, the user interface layer can provide users with an intuitive and unified human-computer interaction entry point, supporting users to initiate various operations such as resource configuration, task scheduling, fault handling and data query. It can also display various information related to platform operation in real time, making it convenient for users to fully grasp the platform status and quickly carry out management work. For example, operation and maintenance personnel can quickly view the virtual machine operation status and handle device alarms through this entry point.

[0026] The application service layer is used to receive and parse user instructions transmitted by the user interface layer; execute business logic operations; handle virtual machine management, image library maintenance, fault analysis and alarms, and data storage management; and feed back the processing results to the user interface layer.

[0027] Specifically, the application service layer can receive and parse user instructions transmitted by the user interface layer, convert the instructions into executable operation logic; centrally execute business logic operations to avoid the inefficiency caused by traditional distributed computing; specifically handle core businesses such as virtual machine management, image library maintenance, fault analysis and alarm, and data storage management, and feed back the processing results such as operation execution status, data query results, and alarm processing feedback to the user interface layer in real time to achieve business closed loop.

[0028] The virtualization interface layer is used to provide virtualization interfaces for underlying hardware devices and virtualization resources.

[0029] Specifically, the virtualization interface layer can provide standardized virtualization interfaces for underlying hardware devices and virtualization resources, building a communication bridge between the application service layer and the underlying resources. On the one hand, it collects resource data such as virtual machine running status, CPU utilization, memory usage, storage read / write speed, and network bandwidth consumption in real time. On the other hand, it accurately transmits the control commands of the application service layer to the underlying hardware devices, while providing stable data transmission support for virtual machine hot migration, ensuring flexible scheduling and efficient collaboration of virtualization resources.

[0030] Optionally, the user interface layer includes a portal interface, a resource management interface, an image library interface, a monitoring and alarm interface, a data query interface, a system configuration interface, and a help center interface. The portal interface displays an overview of the platform's overall operating status, including the number of online virtual machines, resource utilization statistics, the number of unprocessed alarms, and aggregation of core business entry points. The resource management interface supports virtual machine creation, startup, stopping, and migration operations, and displays hardware device distribution and resource allocation. The image library interface provides functions for uploading, downloading, version management, and image deployment configuration of system images. The monitoring and alarm interface displays real-time virtual machine status, various resource usage curves, and lists alarm event details, supporting alarm filtering and export. The data query interface provides retrieval and statistical analysis functions for historical operating data, alarm records, and operation logs, and supports data export. The system configuration interface is used for platform parameter settings, user permission management, interface protocol configuration, and security policy adjustments. The help center interface includes operation guides, frequently asked questions, troubleshooting procedures, and version update logs.

[0031] Optionally, such as Figure 1 As shown, the application service layer includes a virtual machine management module, a logic operation module, a fault and alarm module, a data storage module, and an image library management module. These modules work collaboratively to comprehensively cover the platform's core business needs, ensuring efficient and accurate execution of urban rail transit safety management-related operations.

[0032] Optionally, the virtual machine management module is used to implement full lifecycle management and hot migration of virtual machines. Full lifecycle management includes the creation, startup, shutdown, migration, destruction, and configuration adjustment of virtual machines. When a certain underlying hardware device fails, the virtual machines running on that device can be quickly migrated to other normal hardware devices. The migration process requires only millisecond-level pauses, without affecting core services such as train scheduling, thus ensuring business continuity.

[0033] Optionally, the logic operation module is used to perform core logic operations for urban rail transit control; generate train operation scheduling instructions and signal control strategies; process field data fed back by the trackside terminal; and output control instructions and send them to relevant execution units.

[0034] The logic operation module is used to execute the core logic operation of urban rail train control and is the core of the platform's operation. Train operation scheduling instructions include train speed and station stopping time. The signal control strategy can be the signal light switching logic. It processes on-site data such as track status and train position fed back by the trackside terminal in real time and analyzes them in combination with preset safety rules. It outputs precise control instructions and sends them to the trackside terminal, train control module and other related execution units to ensure safe and orderly train operation.

[0035] Optionally, the fault and alarm module is used to monitor the virtual machine status and resource usage in real time, and trigger an alarm when an anomaly is confirmed.

[0036] like Figure 2 As shown, the virtualization interface can continuously collect data on virtual machine and physical machine resources and apply the collected resources to the application service layer. When an anomaly occurs, both the virtualization interface layer and the logic operation module can generate fault information and transmit it to the fault and alarm module. After receiving the fault information, the fault and alarm module can send the fault information to the data storage module for archiving and storage, so as to facilitate subsequent query and traceability; it can also push the processed fault information to the user interface display module, so as to intuitively present the alarm details on the user interface, so that users can be aware of and handle the fault in a timely manner.

[0037] Optionally, the data storage module is used to store train operation data, virtual machine status data, alarm records, and operation logs. A secure storage strategy ensures data integrity and traceability, while also supporting data backup and recovery, providing reliable support for subsequent data queries, statistical analysis, and fault tracing.

[0038] Optionally, the user interface layer is also used to display the monitoring information and the alarm information based on user query commands. For example, it can be presented in an intuitive chart or list format to facilitate users to quickly obtain key information. For instance, maintenance personnel can view the CPU utilization change curve and related alarm records for the past 7 days through query commands.

[0039] Optionally, the image library management module is used for uploading, verifying, managing versions, controlling permissions, and deleting system images, and maintaining the association configuration between images and virtual machines. This ensures the secure and compliant use of system images, such as authorizing only users to upload or modify images. Version management also prevents virtual machine deployment failures caused by inconsistent image versions, supports quickly deploying new virtual machines using compatible images, and improves deployment efficiency.

[0040] This application embodiment also provides an urban rail safety management system, including an urban rail safety management platform and a trackside terminal; the urban rail safety management platform is communicatively connected to the trackside terminal through a network interface; the trackside terminal is used to receive and execute control commands issued by the safety cloud platform, collect on-site operation data, and feed it back to the safety cloud platform.

[0041] Specifically, the urban rail safety management platform communicates with the trackside terminal through a standardized network interface, replacing the traditional customized protocol. This reduces communication adaptation difficulties and supports interconnection of network-level devices. The trackside terminal is deployed along the track to receive and accurately execute control commands issued by the urban rail safety management platform. It also collects real-time on-site operational data, such as whether there are foreign objects on the track, train location information, and signal light status. This data is then promptly fed back to the urban rail safety management platform through the network interface, forming a closed loop of "platform issuing commands—terminal execution—terminal data feedback—platform analysis and processing." This improves system real-time performance and operational efficiency, while also adapting to old line renovation scenarios, allowing for platform integration without large-scale replacement of terminal equipment.

[0042] In this embodiment, since the underlying resources built on general-purpose computer hardware can interface with the underlying hardware devices and virtualization resources through the virtualization interface layer, the hardware platform is unified, reducing the maintenance difficulty caused by device differences and lowering the professional skill requirements for maintenance personnel. Simultaneously, it avoids compatibility issues between different hardware platforms, providing flexible support for system capacity expansion and performance upgrades without requiring the modification of multiple subsystems, thus reducing the complexity of engineering implementation. Because the application service layer centrally handles core business logic operations such as virtual machine management, image library maintenance, fault analysis and alarms, and data storage management, replacing the multi-node operation mode scattered across the center, station, and trackside in the traditional three-layer architecture, it reduces dependencies and complex protocol interactions between subsystems, shortens instruction transmission and data processing paths, and improves system real-time performance and availability. Furthermore, centralized business logic processing optimizes resource scheduling efficiency, further improving the overall computing performance of the platform. Since the user interface layer provides a unified human-computer interaction entry point, and the application service layer centrally feeds back processing results to this interface layer, it achieves integrated presentation of platform operation, monitoring, and management functions. Users can complete resource configuration, fault handling, and other operations through a single entry point, simplifying the operation process and improving management efficiency.

Based on this understanding, the above technical solutions, in essence or the part that contributes to the prior art, can be embodied in the form of a software product.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
