[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0023] The current train automatic control system (CBTC system), based on functional division, includes multiple subsystems, such as the train automatic protection subsystem ATP, the train automatic operation subsystem ATO, and the train automatic monitoring subsystem ATS. Currently, each subsystem is separately deployed on multiple different hosts, and each subsystem communicates and exchanges data with other subsystems on the vehicle through the MVB train bus. And within each subsystem, the bus network set by each host is used for communication management. For example, the CAN bus network is used for brake communication management within the brake system. Limited by the bus networks set by each host, the operating environments of multiple subsystems of the train automatic control system will be different, resulting in information interaction barriers between the subsystems of the train automatic control system, and further leading to low precision of train automatic control response.

[0024] The integrated brake control platform applicable to rail vehicles proposed by the present invention aims to deploy multiple vehicle subsystems on the integrated brake control platform for unified control through a multi-system fusion control host and a function distribution integration framework, realizing the integration of multiple subsystems. The multi-system fusion control host can provide a unified operating environment and comprehensively carry multiple on-vehicle service systems based on a unified hardwired input / output interface and network interface.

[0025] The integrated brake control platform applicable to rail vehicles proposed by the present invention mainly includes a multi-system fusion control host and a function distribution integration framework. Thus, multiple subsystems are deployed on the integrated brake control platform for unified control through the multi-system fusion control host and the function distribution integration framework. In addition, in order to enable the network communication forms of multiple subsystems and the data between them to be exchanged and shared, the integrated brake control platform also includes an integrated multi-core processor, a data operation operating system, and a time-sensitive network TSN, which will not be elaborated here.

[0026] Figure 1 is a schematic structural diagram of the function distribution integration framework provided by the present invention. As Figure 1 shown, the function distribution integration framework provided by the embodiments of the present application includes: a basic service component, an operating system interface, and at least one application interface.

[0027] Specifically, the integrated brake control platform applicable to rail vehicles proposed by the present invention can support application software including the management system application software TCMS, the train automatic driving system application software ATO, the traction application software, and the brake application software. In the present invention, multiple subsystems are designed in the form of application software to replace the existing solution of separately deploying multiple subsystems on multiple different hosts, facilitating unified management in the function distribution integration framework.

[0028] Figure 2 is a schematic structural diagram of the function distribution integration framework provided by the present invention. AsFigure 2 As shown in the figure, the multi-system integrated control host provided by the embodiment of the present application is configured with a vehicle control unit main board VCU.

[0029] In this embodiment, the application software of each vehicle subsystem can run on the vehicle control unit main board through the application interface. In other words, the application interface in the present invention is a general communication interface provided for the application software. When a certain subsystem needs to be run, only the application software of the subsystem needs to be connected to the function distribution integration framework through the application interface. When the application software of the subsystem runs on the vehicle control unit main board through the application interface, a prompt message indicating that the application software of the subsystem is in the running state can be displayed on the display interface of the operating system currently called by the function distribution integration framework.

[0030] In practical applications, the application software of multiple subsystems can be pre-connected to the function distribution integration framework through multiple application interfaces. When the application software of the subsystem runs on the vehicle control unit main board, a prompt message indicating that the application software of the subsystem is in the running state is displayed on the display interface of the operating system currently called by the function distribution integration framework. When the application software of the subsystem does not run on the vehicle control unit main board, a prompt message indicating that the application software of the subsystem is in the sleep state is displayed on the display interface of the operating system currently called by the function distribution integration framework, thereby distinguishing the running conditions of each subsystem.

[0031] In the present invention, the function distribution integration framework serves as the platform middleware to support the running of the application software on the multi-system integrated control host. With the hardware (operating system interface, application interface, etc.) and communication (real-time data TRDP protocol communication service, security big data technology SDT protocol, etc.) as the basic abstraction layer, it realizes functional safety and application independence. Thus, through the multi-system integrated control host and the function distribution integration framework, multiple subsystems are deployed on the integrated braking control platform for unified control, realizing the integration of multiple subsystems, removing the barriers to information interaction between subsystems, and thereby improving the accuracy of the train automatic control response.

[0032] The service functions matched by the basic service components of the function distribution integration framework include basic data primary and standby redundancy service, real-time data TRDP protocol communication service, input and output IO interface processing information, voting service, clock synchronization service, over-the-air download OTA upgrade service, hardware fault monitoring service, and application scheduling service. Among them, the flexible mobilization of the application software of multiple subsystems can be realized through the application scheduling service, realizing the integration of multiple subsystems. In addition, the service functions also include dynamic deployment service, SDT protocol service, local service management, etc., thereby meeting the requirements of each subsystem.

[0033] In the present invention, the database of the basic service component stores all the data in the multi-system integration control host. In addition, to improve the security of the integrated braking control platform, the basic service matched with the basic service component also has a power-off preservation service and a log recording function service. Thus, through the basic service component, all the application software of the subsystems can call the basic service component to realize functions such as independent primary and standby redundancy, network communication, digital quantity input acquisition, digital quantity output drive, power-off preservation, and log recording, thereby ensuring that each subsystem can operate normally on the integrated braking control platform.

[0034] In addition, to improve the universality of the functional distribution integration framework, the operating system interface in the present invention can adopt a standardized interface. Among them, the standardized interface can be a Portable Operating System Interface of UNIX (POSIX) standardized interface or a POXI standardized interface. The standardized interface supports the calls of different operating systems and will not affect the functional distribution framework. In other words, all the application software in the present invention can call the standardized interface to select and run on each adapted operating system.

[0035] Furthermore, referring to Figure 2 , the multi-system integration control host is also configured with a train control unit power board PWR, an event recording module main board ERM, a security gateway board SGW, an auxiliary operation module main board AOM, an auxiliary operation module power board AOMUPB, and an auxiliary operation module input / output interface board AOM DIO. This ensures that the multi-system integration control host can provide a unified operating environment, computing power resources, and storage resources, provide a unified hardwired input / output interface and network interface, and realize the comprehensive hosting of multiple subsystems. Among them, the structure of the multi-system integration control host in the present invention can be a standardized 3U chassis. All the components of the above multi-system integration control host are distributed inside the 3U chassis, and no limitation is imposed on this.

[0036] The train control unit power board PWR mainly supplies power to the train control unit main board VGU, the event recording module main board ERM, and the security gateway board SGW inside the 3U chassis, thereby ensuring that the train control unit main board VGU, the event recording module main board ERM, and the security gateway board SGW perform data operation and storage during the normal operation of the train.

[0037] In addition, it should be noted that the main board VGU of the train control unit in the present invention is mainly responsible for running the application software of the operation management system TCMS, the application software of the train automatic driving system ATO, the traction application software, and the braking application software, while the main board AOM of the auxiliary operation module is mainly responsible for running the application software of the auxiliary operation system AOM. Thus, when the train enters the sleep stage and the main board VGU of the train control unit does not work, the main board AOM of the auxiliary operation module is used to enable the train to communicate with the ground when it is in the sleep stage, and to implement the sleep wake-up function in the case of needing to wake up the main board VGU of the train control unit.

[0038] Furthermore, the main board ERM of the event recording module is used to monitor the data of the train backbone network and the recording logs of the application software of each vehicle subsystem, and to implement the functions of data recording and transfer. Among them, when the main board ERM of the event recording module detects an abnormality in the data of the train backbone network, it can record this abnormal event and send a notification message to the corresponding processing module to handle the abnormality in a timely manner, so as to ensure that the train automatic control system resumes normal operation in a timely manner. In addition, when the main board ERM of the event recording module detects abnormal data in the recording logs of the application software of each vehicle subsystem, it can send a prompt message to the application software of the subsystem where the abnormal data appears to prompt the application software of the subsystem to conduct a check. Thus, through the main board ERM of the event recording module, multiple subsystems are uniformly managed, and abnormal data that appears in the information interaction between multiple subsystems can be detected in a timely manner, ensuring the normal operation of the automatic control system.

[0039] Furthermore, the security gateway board SWG is used to provide the information security transmission function for the communication between the multi-system fusion control host and the ground communication interface. The input / output interface board AOM DIO of the auxiliary operation module is used to provide the input / output interface function for the train sleep wake-up. The power board AOM UPB of the auxiliary operation module supplies power to the input / output interface board AOM DIO of the auxiliary operation module and the main board AOM of the auxiliary operation module.

[0040] In addition, the multi-system fusion control host is also configured with at least one reserved board interface hole to support the access of other function boards to the multi-system fusion control host. Thus, through the reserved board interface hole, the reconfigurable and extensible functions of the integrated braking control platform are realized. Refer to Figure 2 , the board between the power board PWR of the train control unit and the main board VCU of the train control unit is a reserved board, and a reserved board interface hole is configured on the reserved board. It should be noted that Figure 2 This is only a schematic diagram of the structure of the multi-system fusion control host provided by the present invention, and it does not limit the structure of the multi-system fusion control host. In other words, there is more than one reserved board interface hole on the multi-system fusion control host in the present invention, and the position and quantity of the reserved boards can be set arbitrarily.

[0041] In addition, it should be noted that various types of interfaces are provided on each board of the multi-system fusion control host in the present invention to support the operation of each board. For example, refer to Figure 2 , two external antenna interfaces, a DEBUG interface and a USB interface are configured on the vehicle control unit main board VCU. Among them, the vehicle control unit main board VCU can be fault repaired through the DEBUG interface. Four external antenna interfaces, a DEBUG interface and a CONSOLE interface are configured on the security gateway board SGW. Among them, the CONSOLE interface is used to configure the switch. The functions of various types of interfaces in the present invention are the same as those in the prior art and will not be elaborated here.

[0042] The integrated braking control platform applicable to rail vehicles provided by the present invention includes: a multi-system fusion control host and a function distribution integration framework; the multi-system fusion control host is configured with a vehicle control unit main board, and the function distribution integration framework includes a basic service component, an operating system interface and at least one application interface; the application software of each vehicle subsystem runs on the vehicle control unit main board through the application interface; the application software of each vehicle subsystem can implement the service functions matching the basic service component on the function distribution integration framework through the operating system interface. Thus, through the multi-system fusion control host and the function distribution integration framework, multiple subsystems are integrally deployed on the integrated braking control platform for unified control, realizing the integration of multiple subsystems, removing the barriers to information interaction between subsystems, and further improving the accuracy of train automatic control response.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
