It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0041] This document discloses a real-time simulation online automatic analysis system. Figure 1 This is a system architecture diagram illustrating an embodiment of the real-time simulation online automatic analysis system of the present invention. Figure 1As shown, in this embodiment, the real-time simulation online automatic analysis system includes a human-computer interaction workstation (1), a real-time simulator (2), a test object (3), and a module development workstation (4). The human-computer interaction workstation (1) provides a human-computer interaction environment for software simulation testing. The real-time simulator (2) is used to implement automatic judgment and analysis functions for software simulation testing. The model development workstation is used to develop the simulation model required by the real-time simulator (2). The test object (3) serves as the test object for automatic judgment and analysis of experimental criteria by the real-time simulator.

[0042] Specifically, in this embodiment, the human-computer interaction workstation (1) includes a monitoring module (1.1), a human-computer interaction module (1.2), a test case injection module (1.3), and an analysis report generation module (1.4). The monitoring module (1.1) monitors the operating status of the real-time simulator (2) under different operating modes. The human-computer interaction module (1.2) provides the configuration and command ports of the real-time simulator (2) under different operating modes, thereby enabling the configuration and command control of the real-time simulator (2) under different operating modes. The test case injection module (1.3) implements the test case injection function of the real-time simulator (2) under different operating modes. The analysis report generation module (1.4) generates a simulation test analysis report after the real-time simulator (2) completes software simulation testing.

[0043] Furthermore, in this embodiment, the real-time simulator (2) includes a gateway module (2.1), a control object model module (2.2), an automatic judgment and analysis model module (2.3), a drive and acquisition module (2.4), and a real-time scheduling module (2.5). Among them, the gateway module (2.1) is used to realize the information interaction between the human-computer interaction station and the module development workstation (4) and the control object model module (2.2), thereby realizing the functions of sending and receiving configuration, loading, and control information of the human-computer interaction workstation (1) and the model development workstation (2). The control object model module (2.2) is a dynamic library (DLL, SO, etc.) or executable file (EXE, etc.) for the control object model used in software simulation testing. After the model development workstation (4) has developed the control object model, it is downloaded to the control object model module (2.2) of the real-time simulator (2) to simulate the function of the controlled object. The automatic judgment and analysis model module (2.3) is a dynamic library (DLL, SO, etc.) or executable file (EXE, etc.) for the automatic judgment and analysis model used in software simulation testing. After the model development workstation (4) has developed the automatic judgment and analysis model, it is downloaded to the control object model module (2.2) of the real-time simulator (2) to simulate the function of the controlled object. After defining and analyzing the model, it is downloaded to the automatic judgment and analysis model module (2.3) of the real-time simulator (2) to realize the automatic judgment and analysis of the runtime functions, performance and fault status of the control object model module (2.2). The drive and acquisition module (2.4) is used to simulate the physical signal acquisition and physical signal output functions of the control object model module (2.2) during runtime. The real-time scheduling module (2.5) is used to realize the real-time scheduling of the gateway module (2.1), the control object model module (2.2), the automatic judgment and analysis model module (2.3) and the drive and acquisition module (2.4).

[0044] Furthermore, in this embodiment, for the model information interaction and signal acquisition and driving between the models in the real-time simulator (2), a high-speed data bus and a low-speed data bus are used to connect the modules. Specifically, a high-speed data bus is used for communication between the automatic judgment and analysis model module (2.3) and the control object model module (2.2), and between the driving and acquisition module (2.4) and the control object model module (2.2). The high-speed data bus is used to complete the signal transmission and reception of the constructed control closed-loop signal flow, with a refresh rate of 1000Hz to 5000Hz. A low-speed data bus is used for communication between the control object model module (2.2) and the gateway module (2.1), and between the automatic judgment and analysis model module (2.3) and the gateway module (2.1). The low-speed data bus is used to complete functions such as executable model configuration and loading, model operation monitoring, manual operation drive signal transmission and reception, and test case drive signal transmission and reception, with a refresh rate of approximately 10Hz to 100Hz.

[0045] In this embodiment, the real-time simulator (2) executes the analysis logic of the test simulation test criteria in real time by running the automatic judgment and analysis model module (2.3). When the automatic judgment and analysis model module (2.3) performs real-time automatic judgment and analysis of the software simulation test, the control object model module (2.2) sends a control drive signal to the test object (3) through the drive and acquisition module (2.4). After receiving the signal, the test object (3) returns a control feedback signal to the drive and acquisition module (2.4). After receiving the control feedback signal, the drive and acquisition module (2.4) transmits the control feedback signal to the control object model module (2.2) through the high-speed data bus, and then completes the automatic judgment and analysis of the software simulation test under the scheduling drive of the real-time scheduling module (2.5).

[0046] In addition, in this embodiment, the gateway module (2.1) is also used to realize the communication connection between the automatic judgment and analysis model module (2.3) and the analysis report generation module (1.4) in the human-computer interaction workstation (1), thereby generating the corresponding simulation test analysis report. Specifically, after the automatic judgment and analysis model module (2.3) completes the automatic judgment and analysis of the running status of the control object model module (2.2), it sends the judgment result to the analysis report generation module (1.4) of the human-computer interaction workstation (1) through the gateway module (2.1). Driven by the "test completed" event issued by the automatic judgment and analysis model module (2.3), the analysis report generation module (1.4) generates the corresponding simulation test analysis report.

[0047] Furthermore, in this embodiment, the module development workstation (4) includes a graphical model development module (4.1), a code generation and compilation / linking module (4.2), and a real-time model download and update module (4.3), which are used to complete the graphical development of the simulation model, code generation, and compilation / linking of model files. The graphical model development module (4.1) provides a graphical modeling environment for developing the simulation model required for the real-time simulator (2) and sends the generated simulation model file to the code generation and compilation / linking module. The code generation and compilation / linking module (4.2) parses the received simulation model file and generates the corresponding model code, compilation / linking, and model dynamic library file or executable file. The real-time model download and update module (4.3) sends the simulation model dynamic library or executable model file and receives model update information, and sends the model update information to the graphical model development module (4.1), thereby realizing the real-time download and update of the simulation model's model code and compilation / linking.

[0048] Specifically, in this embodiment, when developing the simulation model, the module development workstation (4) develops the corresponding simulation model according to the requirements of each module in the real-time simulator (2), and provides the model dynamic library (so, dll, etc.) or executable file (exe, etc.) of the simulation model to the outside world. Among them, the simulation module includes the control object model required by the control object model module (2.2), the automatic judgment and analysis model required by the automatic judgment and analysis model module (2.3), and the controller model required by the drive and acquisition module (2.4).

[0049] In this embodiment, the module development workstation (4) conducts a model development process based on the graphical modeling environment in the graphical model development module (4.1) when developing the simulation model. It completes the model file (mdl, etc.) corresponding to the control object model module (2.2) for automatic determination of simulation test execution criteria, and generates the model files (mdl, etc.) corresponding to the automatic determination and analysis model module (2.3) and the drive and acquisition module (2.4) for closed-loop control test simulation. In addition, in this embodiment, the graphical model development module (4.1) can also provide a status information display function for successful model download.
