Description

Technical Field

[0001] The present invention relates to the technical field of design and simulation, and particularly to a running management system and method for a hardware-in-the-loop simulation platform. Background Art

[0002] Existing hardware-in-the-loop simulation platforms generally adopt a single-node independent configuration or independent management mode to implement node configuration or running management of the hardware-in-the-loop simulation platform. When the simulation computer is changed, reconfiguration or setting is required, lacking unified running management.

[0003] Data interaction between each simulation node of the existing hardware-in-the-loop simulation platform is designed in a customized mode. When a node changes, configuration needs to be re-changed, lacking a unified allocation management or configuration management method.

[0004] During the running process of the existing simulation platform, each node is managed in a distributed manner for running control and monitoring management of each node. When a certain node fails, the running fault of the platform cannot be detected in time, lacking a unified running management control method.

[0005] Chinese patent document with publication number CN107528720A and publication date December 29, 2017 discloses a distributed network simulation management system and its running method. The system includes a simulation control subsystem, a monitoring loop, and a simulation loop. The simulation loop includes simulators from multiple PCs. The monitoring loop is connected to the simulation control subsystem through a monitoring interface, and the simulation loop is connected to the simulation control subsystem through an HLA interface. The simulation control subsystem uniformly manages the simulators distributed on each PC, and data interaction between the simulators of the multiple PCs is carried out through the simulation loop.

[0006] The distributed network simulation management system and its running method disclosed in this patent document improve simulation efficiency and running stability. However, when the system changes, it cannot be dynamically and adaptively configured. Summary of the Invention

[0007] In order to overcome the defects of the above-mentioned existing technologies, the present invention provides a running management system and method for a hardware-in-the-loop simulation platform. By configuring system start-stop control and data interaction management, the present invention realizes unified running management of the hardware-in-the-loop simulation platform and solves the problem of dynamic adaptive configuration of the existing hardware-in-the-loop simulation platform when the system changes.

[0008] The present invention is achieved by the following technical solutions: A semi-physical simulation platform operation management system, characterized in that it includes a system configuration management module, a registration management module, a system startup management module, a data interaction management module, a system logout management module, and a node monitoring module that are electrically connected. The system configuration management module is used for configuring the information of each subsystem node, and sending the configuration information to the registration management module, the system startup management module, the data interaction management module, and the node monitoring module. The registration management module is used for the online registration management of each node, receiving node online requests, performing subsystem node matching, and forming a node information registration form. The system startup management module is used for the operation startup of each node. The data interaction management module is used for data interaction between each node. The system logout management module is used for the logout management of each node, and sending the logout instruction or result to the node monitoring module. The node monitoring module is used for online monitoring of the status of each node, and sending the node status to the registration management module, the system startup management module, the data interaction management module, and the system logout management module.

[0009] The subsystem node information includes the identification numbers of each subsystem, the data interaction rule configuration table, the system startup rule configuration table, and the system logout rule configuration table.

[0010] The subsystem nodes include simulation nodes and physical nodes.

[0011] The simulation nodes include semi-physical simulation nodes and full-digital simulation nodes.

[0012] A semi-physical simulation platform operation management method, characterized by including the following steps: S1. Select and configure and import the information of each subsystem node through the system configuration management module; S2. Process the registration requests of each subsystem in sequence according to the time sequence through the registration management module; S3. The system startup management module automatically performs the startup management of each subsystem node according to the startup rule configuration table; S4. After the startup management is completed, according to the data interaction rule configuration table, complete the data interaction management and wait for the simulation start instruction; S5. After the simulation starts, the node monitoring module combines the information of the system logout management module to judge whether the online status of the subsystem node is abnormal exit or normal logout, and complete the node monitoring; S6. After the simulation ends, complete the system logout through the system logout management module according to the system logout instruction.

[0013] The step S2 specifically includes: S21. After the subsystem node runs and starts, send node registration application information to the management system; After the management system receives the node registration application from the child node, it performs node matching, reads the system identification number, and compares it with the system identification number in the system configuration information; S23. If the comparison fails, it displays that the subsystem node registration fails and sends the registration failure information to the subsystem node; S24. If the comparison is successful, the management system assigns a data reception port number to the subsystem node according to the automatic allocation rule of the port; S25. After the data interaction port allocation is completed, it updates the system identification number, data interaction identification number, and data interaction port number of the subsystem node to the registry information, and sends the registration success information and the automatically allocated data interaction port number to the subsystem node; S26. The subsystem node receives the registration result information sent by the management system. If the registration is successful, it initializes according to the allocated data interaction port number. After the initialization is successful, it waits for the start instruction; if the registration fails, the subsystem node automatically cancels the registration; S27. The management system determines whether all system configuration nodes are registered according to the system configuration information. If not, it waits for a new registration application and repeats steps S21 - S26.

[0014] In step S24, assigning a data reception port number to the subsystem node means allocating according to the communication method between the management system and the subsystem.

[0015] The communication method includes Ethernet or fiber optic reflective memory. If the management system is connected to the subsystem through Ethernet, according to the application requirements of the subsystem node, within the set port number range, the port numbers of the data reception ends of the subsystem nodes are sequentially allocated in ascending order of the port numbers; if the management system is connected to the subsystem through fiber optic reflective memory, according to the application requirements of the subsystem node, within the set memory space range, the port numbers of the data reception ends of the subsystem nodes are allocated in ascending order.

[0016] Step S4 specifically includes: S41. After the management system completes the startup of the system configuration node, it retrieves the information in the data interaction rule configuration table; S42. The management system queries the reception identification number and port number of the corresponding receiving subsystem node in the registry according to the sending node identification number and receiving node identification number configured in the data interaction rules; S43. The management system forms a data interaction instruction packet according to the queried reception identification number and port number of the corresponding receiving subsystem node, and sequentially sends it to the ports of the corresponding sending subsystem nodes; S44. The corresponding sending subsystem node updates the target data interaction identification number and port number; S45. The corresponding sending subsystem node sends a flag indicating the completion of startup data interaction to the management system; S46. The management system determines whether the subsystem node has successfully started data interaction; S47. If not successful, it is determined whether the instruction packet sending time has reached the restricted sending time T1. If the restricted sending time T1 has not been reached, steps S43 - S46 are repeated; if the restricted sending time T1 has been reached, the data interaction startup of the subsystem node fails and the startup process ends; S48. The management system determines whether all system configuration nodes have completed data interaction startup. If not, it retrieves the data interaction startup completion information of the system configuration nodes and repeats steps S43 - S47 according to the process; if completed, it waits for the simulation start instruction.

[0017] The specific steps of step S5 include: S51. After each subsystem node starts up, the node monitoring module monitors the online status of each node; S52. The node monitoring module uses online status query. The node monitoring module sends an online status query instruction to the node. If there is no feedback from the node within the set period, it is determined that the node has gone offline; S53. The node monitoring module combines the information of the system logout management module to judge whether the online status of the subsystem node is an abnormal exit or a normal logout.

[0018] The beneficial effects of the present invention are mainly manifested in the following aspects: 1. In the present invention, through the configuration of system start - stop control and data interaction management, the unified operation management of the semi - physical simulation platform is realized, and the problem of dynamic adaptive configuration of the existing semi - physical simulation platform when the system changes is solved.

[0019] 2. In the present invention, through registration management, the problem of automatic allocation of data interaction ports of each subsystem node can be reduced, and manual configuration errors can be reduced.

[0020] 3. In the present invention, through data interaction management, the problem of data interaction management of each subsystem node can be solved, and the unified configuration and management of data interaction of the semi - physical simulation platform can be realized.

[0021] 4. In the present invention, through node monitoring, the problem of system operation status monitoring of the semi - physical simulation platform can be solved, and the unified monitoring management of the status of the semi - physical simulation platform can be realized.

[0022] 5. In the present invention, through system startup management and system logout management, the problem of one - key automatic startup and logout management of the semi - physical simulation platform system can be solved, and one - key startup and logout of the semi - physical simulation platform are realized.

[0023] 6.
