[0001] This application relates to the field of rail transit control technology, and in particular to a train multi-system integrated control system. Background Technology

[0002] With the rapid development of the global rail transit industry, the intelligentization, integration, and low-energy consumption of train control systems have become core directions for technological innovation. Traditional train control architecture, as the core technological support for rail transit vehicles, has developed into a relatively mature distributed system through years of engineering practice. Its basic architecture consists of: each key subsystem, such as train network, traction, auxiliary systems, braking, air conditioning, passenger information, and door control, equipped with an independent control host and actuators. These control hosts are interconnected through communication methods such as multi-function vehicle bus or real-time train data protocols to achieve overall vehicle control functions.

[0003] For a long time, the above architecture effectively supported the reliable operation of rail transit vehicles. However, with the upgrading of the requirements for train life cycle management and the rapid development of intelligent technology, the redundancy problem of the controllers in terms of type and quantity has become increasingly prominent.

[0015] In one possible implementation, the runtime control board includes at least three partitions after embedded virtualization: a first partition, a second partition, and a third partition;

[0016] The first and second partitions are redundant and are used to run the Linux system, executing the same train operation control process (control program); the train operation control process includes the train network operation control process, the train traction operation control process, and the train auxiliary operation control process; the third partition is used to run the real-time operating system to execute the door operation control process and the train braking operation process.

[0018] The passenger service board calls the service control function software to execute the passenger service operation control function process.

The train control architecture provided in this application integrates multi-system control, simplifying the multiple systems into three major integrated control boards according to safety levels. Correspondingly, different controller types need to be designed for the operation control boards with different safety levels, thereby eliminating the independent controllers for each system in the original train control framework, thus reducing the number and types of controllers. The integrated control host includes an operating system layer. The safety function boards, operation control boards, and passenger service boards implement their corresponding control function processes by calling the control function software in the operating system layer. Finally, the integrated control host transmits the control parameters of the safety function boards, operation control boards, and passenger service boards to the various controllers of the train through the communication board group.

[0034] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.

[0035] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0036] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0037] Traditional train control architecture consists of multiple systems, including train network, traction, auxiliary systems, braking, air conditioning, passenger information, and door control. Each system's control host and other actuators are separate entities. These control hosts communicate via MVB (Multifunction Vehicle Bus) or TRDP (Train Real-Data Protocol) to achieve overall vehicle control. In this traditional architecture, each system's control host comprises multiple identical or master-slave controllers, and each system's control host only performs the functions of its own system. This traditional train control architecture is widely used in existing rail transit vehicles. However, it has the following problems:

[0038] Problem 1: Redundancy in controller types leads to high design, troubleshooting, and maintenance costs. Specifically:

[0039] In traditional train control architectures, the control hosts for each system are typically provided by different suppliers, resulting in significant differences in hardware platforms, software interfaces, and communication protocols. This leads to a decentralized control model characterized by "multiple masters and slaves, each operating independently." As trains enter the maintenance and repair phase in large numbers, the diverse types of controllers cause a surge in interface design complexity. Cross-system maintenance requires coordination of technical resources from multiple suppliers, significantly increasing labor and time costs. At the same time, the exit of some early system suppliers or technological iterations have made it difficult to supply spare parts for the original systems, extended maintenance cycles, and even led to the operational dilemma of "system obsolescence but vehicle still in service," severely impacting the economic efficiency of the vehicle's entire lifecycle.

[0040] Question 2: Redundancy in the number of controllers increases operational costs and maintenance burden. Specifically, this manifests as follows:

[0041] In traditional train control architectures, each subsystem's control host requires an independent configuration of basic hardware modules such as power supply boards and communication boards, resulting in an inefficient design characterized by "functional duplication and resource waste." For example, the control hosts for traction, auxiliary, and braking systems are each equipped with independent power supply modules, which not only increases the complexity of the overall vehicle electrical system but also leads to a significant increase in vehicle weight (according to statistics, the weight of the auxiliary power supply system in a traditional train control architecture can increase by 15%-20% compared to a converged architecture), thereby increasing traction energy consumption. In addition, decentralized controllers mean a wide variety of spare parts (a single vehicle needs to be equipped with dozens of dedicated controllers), requiring a large number of different specifications of parts to be stocked during daily maintenance. Inventory management costs and replacement labor costs continue to rise, making it difficult to meet the operational needs of "cost reduction and efficiency improvement" in rail transit.

[0042] Question 3: Insufficient network bandwidth and data interaction capabilities limit intelligent upgrades. Specifically:

[0043] In traditional train control architectures, each subsystem's control host only transmits limited data such as its own system's operating status and fault diagnosis (e.g., current and voltage parameters of the traction system, pressure values ​​of the braking system). The amount of communication data is limited by the bandwidth constraints of MVB (maximum transmission rate of approximately 1.5 Mbps) or TRDP (typical rate of 100 Mbps), making it difficult to achieve deep integration and long-term accumulation of cross-system data. However, with the surge in demand for applications of emerging technologies such as big data analytics and artificial intelligence (AI) in the rail transit field (e.g., fault prediction based on full operational data, energy-saving strategy optimization, passenger behavior analysis), the low bandwidth and small data characteristics of traditional train control architectures have become a technical bottleneck. The decentralized data storage model leads to severe data silos, making it impossible to support intelligent applications with global optimization, thus hindering the leap from "functional implementation" to "intelligent decision-making" in train control.

[0044] To address the aforementioned issues, this application provides a train multi-system fusion control system, which offers a new framework for rail transit train control.

[0045] Optional, see Figure 1 The structural composition diagram of the train multi-system fusion control system provided in this application.

[0046] like Figure 1 As shown, the train multi-system integrated control system includes a fusion control host and a set of safety function boards, operation control boards, passenger service boards, and communication boards installed in the fusion control host. The fusion control host transmits the control parameters of the safety function boards, operation control boards, and passenger service boards to each train controller through the communication boards.

[0047] Among them, the safety function board is a fusion control board that integrates at least train braking operation control function and door operation control function; the operation control board is a fusion control board that integrates at least train network operation control function, train traction operation control function, train auxiliary operation control function, door operation control function and train braking operation control function; and the passenger service board is a fusion control board that integrates at least train air conditioning operation control function and passenger service operation control function.

[0048] Specifically, the traditional train control architecture includes traction control system, network control system, auxiliary control system, braking control system, passenger information system, and air conditioning control system. Based on the safety level of each system's control function, the entire train's functions are divided into safety function domain, operation control domain, and passenger service domain. Correspondingly, the systems mentioned above in the traditional train control architecture are also assigned to their respective domains. It's easy to understand that the safety function domain corresponds to safety function boards, the operation control domain to operation control boards, and the passenger service domain to passenger service boards. The network control system and braking control system belong to the safety function domain; the traction control system and auxiliary control system belong to the operation control domain; and the passenger information system and air conditioning control system belong to the passenger service domain.

[0049] It should be noted that the safety function board, operation control board, and passenger service board are integrated control boards with safety levels ranging from high to low, which are divided according to the safety level of the train's multi-system operation control.

[0050] The safety function levels of the aforementioned integrated control boards gradually decrease from high to low. For example, the safety function level of the safety function board can be SIL4, which is the highest safety level defined in the international standard (IEC 64508 / 61511), requiring the system to be virtually impossible to fail in a hazardous event, and is applicable to the train braking operation control scenario and door operation control scenario in this application; the safety function level of the operation control board can be SIL2, which is a medium safety integrity level, and is applicable to medium-risk scenarios; the safety function level of the passenger service board can be SIL0, which does not require reaching a specific SIL level and is applicable to low-risk scenarios.

[0051] In summary, by dividing the train's systems according to their safety levels for multi-system operation control, the system is streamlined into three major integrated control boards based on safety level. Different safety levels necessitate entirely different hardware and software design requirements for the train controllers. This means different controller types need to be designed for operation control boards with different safety levels. Minimizing the types of hardware and software included in the integrated control system eliminates the need for independent controllers for each system in the original train control framework, thereby reducing the number and types of controllers. In practice, for each safety level's integrated control board, systems of the same safety level should ideally be designed with only one type of hardware and corresponding software. This significantly reduces the variety of hardware and software required.

[0052] For example, see Figure 2 The hardware structure example diagram of the fusion control host provided in this application is shown below.

[0053] like Figure 2As shown, the integrated host is equipped with two power boards, one operation control board, one passenger service board, two TSN communication boards, two safety function boards, and other boards. The operation control board performs network, traction, auxiliary, door, and braking control system functions, while the passenger service board performs air conditioning and passenger service system functions, realizing the control function of one integrated host to run multiple systems.

[0054] The integrated control host includes an operating system layer, in which control function software is deployed.

[0055] Optionally, the safety function board, the operation control board, and the passenger service board can call the corresponding control function software in the operating system layer to execute the corresponding control function process.

[0056] Specifically, for safety function boards, the corresponding control function software at the operating system layer is safety control software, which includes at least braking control software and door control software. In actual operation, the safety function boards call the braking control software to control the train's braking; the safety function boards call the door control software to control the train's doors.

[0057] For the operation control board, the corresponding control function software at the operating system layer is the operation control function software. This software includes at least network control function software, traction control function software, auxiliary control function software, door control function software, and braking control function software. In actual operation, the operation control board calls the network control function software to implement network control of the train; it calls the traction control function software to implement traction control of the train; it calls the auxiliary control function software to implement auxiliary control of the train; it calls the door control function software to implement door control of the train; and it calls the braking control function software to implement braking control of the train.

[0058] It should also be noted that the operation control board includes at least three partitions after embedded virtualization: a first partition, a second partition, and a third partition; wherein, the first and second partitions are redundant and are used to run the Linux system and execute the same train operation control process, specifically, the train operation control process includes the train network operation control process, the train traction operation control process, and the train auxiliary operation control process; the third partition is used to run the real-time operating system and is used to execute the door operation control process and the train braking operation process.

[0059] Embedded virtualization technology is a technology that creates multiple isolated execution environments on an embedded system hardware platform through a virtualization layer (Hypervisor), allowing different operating systems or applications to coexist securely and efficiently on the same physical hardware. The core objective of this technology is to improve system flexibility, security, and resource utilization through resource abstraction and isolation. It is suitable for resource-constrained but functionally complex embedded scenarios such as the train multi-system fusion control system provided in this application.

[0060] For the passenger service board, its corresponding control function software at the operating system layer is service control function software, which includes at least air conditioning control function software and passenger service control function software. In actual operation, the passenger service board calls the air conditioning control function software to control the train's air conditioning; the passenger service board calls the passenger service control function software to control passenger services on the train.

[0061] For example, see Figure 3 This application provides an example diagram of the composition architecture of the train multi-system integrated control system.

[0062] like Figure 3 As shown, the train multi-system integrated control system mainly consists of four layers: hardware layer, operating system layer, middleware layer, and application layer.

[0063] It's important to note that the control domain board within the fusion control host is virtualized into three partitions via the Hypervisor operating system monitoring software. Partitions 1 and 2 run Linux operating systems, providing redundancy by running the same functional software. The third partition runs a real-time operating system, executing SIL2 safety-related control logic to ensure real-time performance. Specifically, partitions 1 and 2 on the control domain board run CCU, traction, and auxiliary system control software on their Linux operating systems; partition 3 runs braking and door safety-related software.

[0064] As mentioned above, the safety function board, operation control board, and passenger service board are integrated control boards whose safety levels are classified from high to low according to the safety levels of the train's multi-system operation control. Correspondingly, the functional safety levels of the safety control software corresponding to the safety function board, the operation control software corresponding to the operation control board, and the service control software corresponding to the passenger service board in the operating system layer also decrease from high to low.

[0065] Optionally, the converged control host includes a multi-core CPU main control board, which comprises a safety function board, an operation control board, a passenger service board, and a communication board group. In other words, the safety function board, operation control board, passenger service board, and communication board can all be referred to as the multi-core CPU main control board. Specifically, the safety function board, operation control board, and passenger service board are all installed on the backplane of the converged control host, and these boards exchange data via Ethernet communication on the backplane.

[0066] Based on this, the security control software corresponding to the security function board, the operation control software corresponding to the operation control board, and the service control software corresponding to the passenger service board in the operating system layer run on the multi-core CPU main control board using the aforementioned embedded virtualization technology. Each system software runs as an independently executable program on any virtualized operating system partition on its corresponding integrated control board, selecting the appropriate operating system to run according to the software's operational requirements. Integrating the control functions of multiple systems onto the same multi-core CPU fully utilizes hardware resources and enables low-level data sharing.

[0067] The integrated control host transmits control parameters from the safety function boards, operation control boards, and passenger service boards to each train controller via communication boards. The communication board group will be described in detail below.

[0068] The communication board group includes at least two TSN (Time-Sensitive Networking) communication boards. Each TSN communication board includes two independent TSN network hardware interfaces. The TSN communication board transmits the operation control parameters of the operation control board, the passenger service parameters of the passenger service board, and multimedia data to the train controller through the TSN network hardware interface. Specifically, the TSN network hardware interface can realize the control of the operation control and passenger service domain within the whole machine, as well as the sharing and transmission of audio and video data.

[0069] Specifically, the fusion control host in the train multi-system integrated control system is connected to the TSN network via a TSN communication board, and communicates with the train controller through the TSN network. The TSN network includes a TSN network switch group, and each TSN network switch in the TSN network switch group communicates with the fusion control host and all controllers on the train via TSN lines.

[0070] It should be noted that the various boards in the integrated control host communicate via Ethernet or PCIe bus on the backplane, and are provided with the same redundant power supply through the power supply board within the integrated control host. The communication board group within the integrated control host is responsible for the network communication of the entire integrated control host to the outside world. Therefore, the train multi-system integrated control system provided in this application uses a TSN network to realize the control of the train control network and passenger information network, as well as the integrated transmission of multimedia data, thereby achieving data sharing of the train control terminal.

[0071] Specifically, control data and video data can be transmitted between multiple devices connected by several TSN network cables. Each cable connects one device to a TSN switch, forming a TSN communication network. A device responsible for control can then send control data to this TSN network, which all other devices within the network can receive. Similarly, another device sends its audio and video data to the same TSN network, which all other devices within the network can receive. This requires specific design considerations in both the communication equipment's software and hardware to ensure that control data and audio data are transmitted within a single TSN network. Because the volume of audio and video data is very large, it can cause network storms, leading to control data transmission failures and control function malfunctions. Therefore, under normal circumstances, two independent control networks and audio / video networks are used to transmit control data and audio / video data respectively. In summary, the TSN network integrates train control and audio / video data transmission, achieving hardware and data fusion of the whole vehicle control system and a high degree of standardization of the whole vehicle control platform. It also enables the shared transmission of control and audio / video data, reduces the complexity of the whole vehicle network, reduces network cabling, greatly shortens the design and maintenance time of rail transit vehicles, saves costs, and forms a unified data platform, laying the foundation for further in-depth application of AI technology.

[0072] For example, see Figure 4 The structural composition of the TSN network provided in this application is illustrated in the following diagram.

[0073] like Figure 4 As shown, the traction controller and auxiliary controller communicate with the fusion host through the TSN communication network. The network communication diagram consists of three TSN network switches (ECNN, a total of 18 ECNN devices) on each car connected to each other to form a TSN network. The fusion host, TCU (traction control execution unit), ACU (auxiliary control execution unit), and DCU (door control execution unit) on each car are connected to the ECNN through two redundant TSN lines, so that all devices on the vehicle are connected to the TSN network.

[0074] It is understood that the train multi-system integrated control system provided in this application integrates the control host functions of multiple control systems on a train onto a single multi-core CPU using embedded virtualization technology. Then, according to the safety level of the train's multi-system operation control, the overall vehicle functions are divided into a safety function domain, an operation control domain, and a passenger service board domain. The safety function domain implements the safety control function flow for the train in the form of safety function boards; the operation control domain implements the operation control function flow for the train in the form of operation control boards; and the passenger service board domain implements the passenger service operation control function flow for the train in the form of passenger service boards. This process specifically achieves the integrated operation of multiple system function software on the same hardware CPU, enabling isolated execution, sharing of hardware resources and data, reducing the transmission links of control command sets and data between systems, shortening the transmission cycle, and improving train control response time and control accuracy.

[0075] Therefore, this application employs a novel integrated control host that combines the control functions of various systems in traditional rail transit trains, such as network, traction, auxiliary, braking, air conditioning, passenger information, and door control, into a single integrated host. During this process, the existing independent controllers and control host of each subsystem on the traditional train, as well as functions involving microsecond-level signal processing such as traction and auxiliary functions, remain on the original controller of the traditional train and are encapsulated into standard electrical interfaces. Control parameters are transmitted to the original controller on the traditional train via the TSN communication network.

[0076] For example, the control function software of various systems such as train network, traction, auxiliary, braking, air conditioning, passenger information, and gate control running in the new integrated host is divided into operation control domain, passenger service domain, and safety function domain according to functional domains. The operation control domain is implemented by one or more circuit boards and runs the functional software related to train operation control such as train network, traction, auxiliary, braking, and gate control. Its functional safety level requirement is SIL2. The passenger service domain is implemented by one or more circuit boards and runs the functional software related to train service such as air conditioning and passenger information. Its functional safety level requirement is SIL0. The safety function domain runs the safety function software related to braking and gate control. Its functional safety level requirement is SIL4.

[0077] For example, see Figure 5 The diagram shows an example of internal communication within the fusion control host provided in this application.

[0078] The fusion control host includes power boards 1 and 2 for powering all other boards, an operation control domain board, a passenger service domain board, reserved boards, a switch board, two TSN communication boards, two safety function boards, two safety input boards, and two safety output boards.

[0079] The operation control domain board, passenger service domain board, reserved boards, switch board, and two TSN communication boards communicate via Gigabit Ethernet or PCIe bus. The two TSN communication boards, two safety function boards, two safety input boards, and two safety output boards communicate via CAN or other methods.

[0080] In summary, the train multi-system integrated control system provided in this application includes an integrated control host and safety function boards, operation control boards, passenger service boards, and communication boards, which are divided according to the safety level of the train's multi-system operation control. Specifically, the safety function boards integrate braking control and door control; the operation control boards integrate network control, traction control, auxiliary control, door control, and braking control; and the passenger service boards integrate air conditioning control and passenger service control. The train control architecture provided in this application integrates multi-system control, simplifying the multiple systems into three major integrated control boards according to safety levels. Correspondingly, different controller types need to be designed for the operation control boards with different safety levels, thereby eliminating the need for independent controllers for each system in the original train control framework, thus reducing the number and types of controllers. The integrated control host includes an operating system layer. The safety function boards, operation control boards, and passenger service boards implement their corresponding control function processes by calling the control function software in the operating system layer. Finally, the integrated control host transmits the control parameters of the safety function boards, operation control boards, and passenger service boards to the various controllers of the train through the communication board group.
