Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The embodiment of the present invention provides a method for dynamically deploying vehicle-mounted application software, such as Figure 1 As shown, including but not limited to the following steps:

[0030] Step S1: receiving an application management request sent by a target sub-board terminal, wherein the application management request is generated by the target sub-board terminal according to a received first configuration file;

[0031] Step S2: according to the application management request, sending application management data to the target sub-board terminal, so that the target sub-board terminal loads the application management data according to the first configuration file.

[0032] The execution subject of the dynamic deployment method of vehicle-mounted application software provided by the embodiment of the present invention is the mainboard terminal.

[0033] Specifically, in the embodiment of the present invention, all vehicle-mounted software applications and services (such as Figure 2 APP1-APP shown in n ), uniformly deployed on a certain in-vehicle intelligent terminal with sufficient storage space, as the main board terminal (MB) of the dynamic deployment solution, which comprehensively carries the management of all in-vehicle dynamic deployment applications. All in-vehicle terminals except the main board terminal are regarded as sub-board terminals (SB) in the dynamic deployment solution.

[0034] Optionally, two MBs may be set in all vehicle-mounted terminals, but different priorities may be set between the two MBs, that is, a spare MB may be set to form a redundant design.

[0035] Optionally, the dynamic deployment method of the vehicle-mounted application software provided by the embodiment of the present invention may utilize a management and deployment server (Service Management & Deployment, SMD) based on a configuration file to implement service management of data interaction.

[0036] Since the SMD needs to implement data interaction between the MB and all SBs based on a high-bandwidth network, in the embodiment of the present invention, the MB and all SBs communicate through the high-bandwidth network, and the embodiment of the present invention does not specifically limit the high-bandwidth network.

[0037] Next, use any SB (hereinafter referred to as the target SB) to perform APP x The version update of APP is taken as an example to illustrate. x It is APP1-APP n one of the.

[0038] Each SB has a corresponding configuration file. The configuration file corresponding to the target SB is called the first configuration file. The first configuration file records the APP x Version update requirements.

[0039] When the target SB is powered on, the SMD service on the target SB reads the first configuration file and obtains the APP x Therefore, an application management request is sent to the MB, wherein the application management request is the SMD service according to the APP recorded in the first configuration file x Generated by version update requirements.

[0040] After receiving the application management request sent by the target SB, the MB reads the application management request through the SMD service on the MD to obtain the application management request carried in the application management request. x A request to update the version of the

[0042] The target SB receives the latest version of APP x After that, the corresponding SMD service reads the first configuration file and learns that the APP x After the version is updated, load the latest version of APP in the application management data x .

[0043] The SMD service of the target SB completely reads the first configuration file to start the local service functions of the target SB in sequence.

[0044] It should be noted that the above embodiment is only based on APPx The example of updating the version of is used to illustrate. The version information of the system applications and service software in each target SB can also be uniformly managed through the SMD service of the MB, which will not be elaborated here.

[0045] The dynamic deployment method of vehicle-mounted application software provided in an embodiment of the present invention realizes the dynamic deployment of vehicle-mounted application software by constructing a distributed architecture in which a mainboard terminal connects multiple SBs through high-bandwidth train network communication to provide SMD services based on configuration files, thereby effectively improving the unified management level of software applications and services in the vehicle-mounted system and reducing the debugging and maintenance costs of the system.

[0046] Based on the content of the above embodiment, as an optional embodiment, the receiving of the application management request sent by the target sub-board terminal specifically includes:

[0047] Establishing an Ethernet train backbone network connection with the target sub-board terminal;

[0048] Based on the Ethernet train backbone network, the application management request sent by the target sub-board terminal is received.

[0049] Among them, the Ethernet Train Backbone (ETB) introduces the high bandwidth, fast speed, and good real-time performance of industrial Ethernet into the train network to adapt to the future development direction of train network systems. The difference between ETB and industrial Ethernet lies in the network topology structure. The spanning tree is prohibited, and the rapid spanning tree protocol and network initialization protocol can be used.

[0050] In the embodiment of the present invention, the MB and all SBs communicate through the high-bandwidth ETB. When any SB is powered on, the local SMD service of the SB sends an application management request to the SMD service of the MB through the ETB bus according to its configuration file to obtain local applications. Then, the SMD service of the MB is used to uniformly manage the version information of all system applications and service software, so as to respond to the application management request of the SB and feed back application management data to it, so that the local SMD service of the SB can load the application management data according to the information of its configuration file and start local services in sequence.

[0051] The dynamic deployment method of vehicle-mounted application software provided by the embodiment of the present invention can reduce the debugging and maintenance intensity of the train signal system through the dynamic deployment solution of application software based on ETB, and realize the unified management of software applications and services in the vehicle-mounted system.

[0052] It should be noted that in the embodiment of the present invention, the SMD service needs based on the configuration file form are comprehensively considered, and the ETB communication network is configured for MB and each SB to communicate and interact to meet the high bandwidth requirements of the SMD service. Other high-bandwidth communication modes can also be used. Therefore, the construction of the ETB communication network is not regarded as limiting the protection scope of the embodiment of the present invention.

[0053] Based on the content of the above embodiment, as an optional embodiment, sending the application management data to the target sub-board terminal according to the application management request specifically includes:

[0054] Reading a second configuration file;

[0055] generating the application management data according to the second configuration file and the application management request;

[0056] Based on the Ethernet train backbone network, the application management data is sent to the target sub-board terminal.

[0057] The second configuration file refers to a configuration file configured to the MB according to actual needs, so that the SMD service of the MB can uniformly manage the version information of all system applications and service software according to the second configuration file.

[0058] Specifically, in an embodiment of the present invention, after receiving an application management request sent by a certain SB, the SMD service of the MB parses the application management request, and generates application management data in combination with the second configuration file, wherein the application management data corresponds to the application management request, and the process of generating the application management data can be understood as a step for the SMD service of the MB to manage the application management request of the target SB.

[0059] Finally, the application management request is sent to the target SB through the ETB communication network pre-built between the two, so that the SMD service of the target SB can manage its application. The management can be loading a new APP, deleting a pre-loaded APP, updating the version of at least one APP, etc., which is not limited in the embodiments of the present invention.

[0060] The dynamic deployment method of vehicle-mounted application software provided by the embodiment of the present invention can obtain and enable software applications and services in the MB system by modifying the configuration file of the SMD service of the target SB without further manual management and deployment, making the deployment of software applications and services in the vehicle-mounted system more flexible. At the same time, the application programs running in each SB can be reasonably allocated according to actual needs, making it easier to balance the computing power resources of each intelligent terminal device in the system.

[0061] Based on the content of the above embodiment, as an optional embodiment, a first vehicle-mounted management deployment server is pre-loaded in the target sub-board terminal;

[0063] The generating the application management data according to the second configuration file and the application management request includes:

[0064] Using a pre-loaded second vehicle management deployment server, reading the second configuration file;

[0065] Analyzing the application management request according to the reading result;

[0066] The application management data is generated according to the analysis result.

[0067] like Figure 2 As shown, an SMD service is separately configured in the MB and each SB, that is, the dynamic deployment method of the vehicle-mounted application software provided by the embodiment of the present invention is a dynamic deployment solution for distributed architecture software applications and services, specifically involving an SMD service based on the form of a configuration file, which can be based on a high-bandwidth Ethernet train backbone network ETB, so as to support the transmission of executable files of software applications and services through the ETB bus.

[0068] All vehicle-mounted software applications and services that meet the conditions for dynamic deployment are uniformly deployed on a certain vehicle-mounted intelligent terminal with sufficient storage space, which serves as the main board MB of the dynamic deployment solution to comprehensively carry all vehicle-mounted dynamic deployment applications. All intelligent terminals connected to the ETB bus except the main board are the sub-board SB in the dynamic deployment solution; all terminals in the vehicle system that support dynamic deployment functions must be directly or indirectly connected to the ETB bus.

[0069] When SB is powered on, the local SMD service obtains local applications from the SMD service of MB through the ETB bus according to the configuration file. The version information of system applications and service software is centrally managed by the SMD service of MB. The local SMD service starts local services in sequence according to the configuration file information.

[0070] The dynamic deployment method of vehicle-mounted application software provided in the embodiment of the present invention realizes the unified management of software applications and services in the vehicle-mounted system, and reduces the debugging and maintenance costs of the system; and by modifying the configuration files of the MB and the SMD services of each SB, the software applications and services in the system can be acquired and enabled without manual management and deployment, making the deployment of software applications and services in the vehicle-mounted system more flexible and easier to balance the computing power resources of each intelligent terminal device in the system.

[0071] Based on the content of the above embodiment, as an optional embodiment, the method may further include: performing encrypted file configuration processing on the first configuration file and the second configuration file.

[0072] In the embodiment of the present invention, the configuration files of the MB and the SMD services of each SB may adopt a flexible and convenient plain text configuration method, or may adopt a more secure encrypted file configuration method.

[0073] The encrypted file configuration method may be implemented by using a related encryption tool, or may be based on a password encryption technology to configure a set of unified or independent passwords for each configuration file, etc., which is not specifically limited in the embodiment of the present invention.

[0074] The dynamic deployment method of vehicle-mounted application software provided by the embodiment of the present invention facilitates the authority management of the train system by encrypting the configuration file, so as to effectively improve the security level of the dynamic deployment of the vehicle-mounted application software.

[0075] Based on the above embodiments, the dynamic deployment method of vehicle-mounted application software provided by the embodiments of the present invention is characterized in that the target sub-board terminal includes one or more of a whole vehicle controller board, a human-machine interaction interface control board, and a vehicle remote input and output control board; the whole vehicle controller board is integrated with a train automatic driving module and a train automatic control module; the human-machine interaction interface control board is integrated with a human-machine interaction interface module and a train diagnostic module; the vehicle remote input and output control board is integrated with a digital input and output module and an analog input and output module.

[0077] On-board terminal devices such as the Train Control and Communication (TCC) board, the Vehicle Control Unit (VCU) board, the Man Machine Interface (MMI) board, and the Remote Input / Output Module (RIOM) board are mounted on the on-board ETB bus to form the on-board Train Control and Management System (TCMS).
