Description

Technical Field

[0001] The present invention relates to the field of computer simulation technology, and in particular to a simulation model packaging method, system, device and medium based on the FMI standard. Background Art

[0002] A simulation model is a scientific model or engineering model built with mathematical expressions and programming languages ​​in a computer simulation system to simulate real scientific or engineering physical processes. The simulation modeling tool platforms in different technical fields have different modeling methods, modeling languages, and model interface definitions, which makes it impossible to universally use and reuse simulation models built by different simulation modeling tool platforms.

[0003] In the prior art, an interface standard for simulation model exchange and collaboration, FMI (Functional Mock-up Interface for Model Exchange and Co-Simulation), is developed. FMI is an open standard for exchanging simulation models between different simulation tools. The FMI standard defines a container and an interface, which defines XML files (model description files), binary files, and model code files to exchange dynamic simulation models, and packages them into FMU model files. FMU (Functional Mock-up Unit) is a model unit that complies with the FMI standard, and can be imported and used by different simulation software.

[0004] However, when constructing a simulation test system based on the FMI standard, component models created by various simulation tools are imported and assembled into a complex simulation system. Since the FMI standard only roughly defines the interface attributes such as input, output, data type, etc. of the model interface, there may be hundreds or thousands of interface parameters when simulating a complex simulation system. In the absence of parameter classification management, different types of parameters such as the entity parameters, test task parameters, and signal parameters of the simulation model need to be set and managed, and they need to be browsed, searched, and set one by one in a huge list of parameters, which limits the speed and accuracy of building the simulation test system. In addition, when the parameterized simulation test system is driven by a data table, the system operation efficiency is low.

[0005] Therefore, those skilled in the art are in urgent need of a simulation model encapsulation method that can implement classified management of simulation model interface parameters without affecting FMI standard compatibility, so as to improve the efficiency of simulation test system construction and test deployment and operation. Summary of the invention

[0006] 1.

DETAILED DESCRIPTION

[0020] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0021] refer to Figure 1As shown, an embodiment of the present invention proposes a simulation model packaging method based on the FMI standard, which includes: first, in response to the packaging requirement information in the simulation model, a model description template file is created; secondly, a parameter category directory is set in the model description template file, and a remark description item is configured under the parameter category directory to add preset model parameter category description information; then, based on the modified model description template file, in combination with the acquired FMI standard model code file, a model description file containing model parameter category description information is generated; then, based on the acquired system environment information for simulation operation of the simulation model, the FMI standard model code file is compiled to generate a binary dynamic library of the simulation model suitable for the specified system environment; finally, according to the FMI standard model directory structure, the model description file, the model code file, the binary dynamic library and the acquired simulation model description file are packaged to form a deployable target simulation model file.

[0022] This embodiment adopts a technical solution of adding preset model parameter category description information to the remark item configured under the parameter category directory of the model description template file, so that the classification identification of the interface parameter information of the simulation model is realized without affecting the compatibility of the FMI standard. Compared with the prior art, when forming a simulation test system, the simulation model that uses the classification identification of interface parameters and is compatible with the FMI standard interface can repeatedly call the simulation model component and set different interface parameter tables according to the requirements of the simulation test purpose, system composition plan, test outline, etc., so as to establish a test simulation system composed of different simulation models and physical equipment, realize the reusability of the simulation model component, and flexibly realize the expected simulation test goals.

[0023] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0024] Specifically, refer to Figure 1 As shown, this embodiment proposes a simulation model packaging method based on the FMI standard, which includes: S1. In response to the requirement information encapsulated in the simulation model, a model description template file is created.

[0025] For example, the simulation model is encapsulated as an FMU model according to the FMI standard, and the file structure of the FMU model includes at least the model implementation program structure, the model description file, and the model description file. The model implementation program structure also contains the model code file (Sources) and the binary code file (Binaries). The model description file is used to define all model information and interface parameter information, so that the FMU model provides a universal model interface across tool platforms through the model description file. The model description file is used to provide model-related documentation. Before generating the model description file, it is also necessary to create a model description template file to define the document structure and data type of the model description file to complete the automatic generation of the model description file and data consistency verification.

[0026] In this embodiment, step S1 may include the following sub-steps S11-S13: S11. Obtain packaging requirement information of the simulation model, where the requirement information includes data type, document structure, and data content.

[0027] S12. Create a model parameter category description template file based on the data type and document structure.

[0028] S13. Create a model description template file based on the model parameter category description template file, combined with the document structure and data content.

[0029] S2. Set a parameter category directory in the model description template file, and configure a remark item under the parameter category directory to add preset model parameter category description information.

[0030] Since the structure of the model description file in the simulation model encapsulated according to the FMI standard cannot be modified at will, it is impossible to add specific model parameter category description information in the model description file. Therefore, this embodiment selects to add preset specific model parameter category description information in the model description template file, so that the subsequent model description file generated based on the model description template file can realize the classification identification of the interface parameter information of the simulation model without affecting the compatibility of the FMI standard.

[0031] Further explanation: the model description template file is provided with a parameter category directory and a model variable directory. The parameter category directory is used to define the category of interface parameters in the simulation model (such as position, velocity, acceleration, etc.) and the corresponding dimensional units, etc.; the model variable directory is used to define the name, data type (such as integer, floating point, Boolean, string, enumeration, etc.), input / output type, and reference to the interface parameter category defined in the parameter category directory. Furthermore, the remark item is configured under the parameter category directory. By adding a preset character string of model parameter category description information in the remark item, the purpose of classifying the simulation model interface parameters can be achieved without affecting the compatibility of the simulation model in the FMI standard.

[0032] In this embodiment, step S2 may include the following sub-steps S21-S23: S21. Generate model parameter category description information of the simulation model according to packaging requirement information of the simulation model. The model parameter category description information includes model entity parameters, model task parameters and model signal interface parameters.

[0033] Furthermore, model entity parameters are mainly used to describe the physical characteristic parameters of simulation model entities (such as aircraft, cars, ships, boats, etc.), such as size, mass, center of gravity, center of buoyancy, fluid dynamic parameters and other parameters related to the inherent characteristics of specific entities. And when the simulation system is built, the model entity parameters can be defined in an independent data table. By changing the parameters, the simulation of different specifications and models of the same entity model can be realized without re-programming the model.

[0034] Model mission parameters are mainly used to describe variable condition parameters such as initial conditions, mission objectives, route planning, mission environment parameters, etc. during simulation tests. When building a simulation system, model mission parameters can be defined differently through multiple parameter tables to achieve multi-condition or multi-voyage simulation test management and batch operation during the simulation test.

[0035] Model signal interface parameters are mainly used for signal interfaces when multiple simulation models are assembled and connected, to achieve multi-model interconnection and communication during simulation of complex large systems, and to build a semi-physical simulation system.

[0036] S22. By controlling a preset automation tool, a parameter category directory is set in the model description template file, and a remark description item is configured under the parameter category directory.

[0037] S23. By controlling the automation tool, the model parameter category description information is added to the remarks item to obtain a modified model description template file.

[0038] S3. Generate a model description file containing model parameter category description information based on the modified model description template file and the acquired FMI standard model code file.

[0039] According to the modified model description template file, the interface parameter type and number of interface parameters of the actual simulation model, as well as the functional function interface prototype, defined in the corresponding header file in the FMI standard model code file, are converted into a model description file, thereby completing the standardization and conversion process of the FMU model.

[0041] F2. Convert the source code file into the FMI standard model code file based on the FMI standard header file.

[0042] Among them, the header files of the FMI standard include: data type definition header file, which is used to determine the correspondence between C language data types and FMI standard language data types, as well as to determine the input and output parameter types of model function functions; function type definition header file, which is used to determine the model function function type of the FMI standard; function interface header file, which is used to determine the prototype of the model function function of the FMI standard.

[0043] The original model code source file is converted into a model code file of the FMI standard, and the model code source file is added to the data type definition header file, the function type definition header file and the function interface header file. The C language data types of the relevant data and variables in the original code are replaced with the language data types of the FMI standard, and the model function and interface parameter types are replaced with the FMI standard definition types to form source code that conforms to the FMI standard, and the source code is packaged to obtain the model code file of the FMI standard.

[0044] In this embodiment, step S3 may include the following sub-steps S31-S33: S31. Parse the FMI standard model code file to obtain FMI model information including interface parameter type, interface parameter quantity and model function prototype.

[0045] S32. Add the FMI model information to the modified model description template file according to the structural information of the modified model description template file to obtain an initial model description file.

[0047] S4. Compile the FMI standard model code file according to the obtained system environment information for simulation operation of the simulation model to generate a binary dynamic library of the simulation model suitable for the specified system environment.

[0048] According to the system environment information of the simulation model or the target platform for the expected simulation operation, select an appropriate compiler (such as VS compiler or GCC compiler), compile the FMI standard model code file to generate a binary dynamic library of the FMU model (.dll dynamic library under win64 or .so dynamic library under linux64, etc.), and package the compiled binary dynamic library to obtain the FMI standard binary code file.

[0049] In this embodiment, step S4 may include the following sub-steps S41-S43: S41, obtaining system environment information for simulation model to perform simulation operation.

[0050] S42. Determine a compiler for compiling the content of the FMI standard model code file according to the system environment information.

[0053] S5. According to the model directory structure of the FMI standard, the model description file, model code file, binary dynamic library and the description file of the obtained simulation model are packaged to form a deployable target simulation model file.

[0054] In this embodiment, step S5 may include the following sub-steps S51-S54: S51, obtaining a description file of the simulation model, and obtaining a model directory structure including a model binary code file directory, a model description file directory, a model code file directory, and a model description file directory.

[0055] S52. Create a folder according to the directory structure of the FMI standard.

[0056] S53, copying the model description file, the model code file, the binary dynamic library and the description file of the simulation model to the corresponding directory to obtain the target simulation model file package.

[0057] S54, compressing the target simulation model file package to obtain the target simulation model file to complete the packaging of the reusable simulation model.

[0058] In a specific embodiment, the simulation model packaging method based on the FMI standard described in the above steps S1-S5 is used to package the underwater unmanned submersible simulation model UUV.mdl into a reusable semi-physical simulation model UUV.fmu. This model is reusable when assembling and building a semi-physical test system, and does not rely on the original modeling platform.
