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 or engineering model constructed using mathematical expressions and programming languages ​​in a computer simulation system. It is used to simulate real-world scientific or engineering physical processes. Simulation modeling tool platforms in different technical fields have different modeling methods, modeling languages, and model interface definitions, making them difficult to integrate and reuse.

[0003] In existing technology, an open standard for exchanging simulation models between different simulation tools has been established: the Functional Mock-up Interface for Model Exchange and Co-Simulation (FMI). The FMI standard defines a container and an interface for exchanging dynamic simulation models by defining XML files (model description files), binary files, and model code files. These files are then packaged into FMU model files. FMUs are FMI-compliant model units that 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 properties 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 browsed, searched, and set one by one in a huge list of parameters. This limits the speed and accuracy of building the simulation test system, and when the parametric 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 the compatibility of the FMI standard, so as to improve the efficiency of simulation test system construction and test deployment and operation. Summary of the Invention

[0064] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0065] refer to Figure 1 As shown, an embodiment of the present invention proposes a simulation model packaging method based on the FMI standard, which includes: first, creating a model description template file in response to the packaging requirement information in the simulation model; second, setting a parameter category directory in the model description template file, and configuring a remark description item under the parameter category directory to add preset model parameter category description information; then, based on the modified model description template file and in combination with the obtained FMI standard model code file, a model description file containing model parameter category description information is generated; then, based on the obtained 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, model code file, binary dynamic library and the obtained simulation model description file are packaged to form a deployable target simulation model file.

[0066] 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, thereby achieving the classification identification of the interface parameter information of the simulation model without affecting the compatibility of the FMI standard. Compared with the existing technology, when constructing a simulation test system, a 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., to establish a test simulation system composed of different simulation models and physical equipment, realize the reusability of the simulation model component, and flexibly achieve the expected simulation test goals.

[0067] To better understand the above technical solutions, 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. Rather, 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.

[0068] Specifically, refer to Figure 1 As shown, this embodiment proposes a simulation model packaging method based on the FMI standard, which includes:

[0069] S1. In response to the requirement information encapsulated in the simulation model, a model description template file is created.

[0070] For example, a simulation model is encapsulated as an FMU model according to the FMI standard. The file structure of the FMU model includes at least a model implementation program structure, a model description file, and a model specification file. The model implementation program structure further includes model code files (Sources) and binary code files (Binaries). The model description file defines all model information and interface parameter information, enabling the FMU model to use a universal model interface across tool platforms through the model description file. The model specification file provides model-related documentation. Before generating the model description file, a model description template file must be created to define the document structure and data types of the model description file, enabling automatic generation of the model description file and data consistency verification.

[0071] In this embodiment, step S1 may include the following sub-steps S11-S13:

[0072] S11. Obtain packaging requirement information of the simulation model, where the requirement information includes data type, document structure, and data content.

[0073] S12. Create a model parameter category description template file based on the data type and document structure.

[0074] S13. Create a model description template file based on the model parameter category description template file, combined with the document structure and data content.

[0075] 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.

[0076] Because the structure of the model description file in a simulation model encapsulated according to the FMI standard cannot be modified at will, specific model parameter category description information cannot be added to the model description file. Therefore, this embodiment adds preset specific model parameter category description information to the model description template file. This allows the model description file subsequently generated based on the model description template file to implement the classification identification of the simulation model's interface parameter information without affecting FMI standard compatibility.

[0077] Further explanation: The model description template file includes a parameter category directory and a model variable directory. The parameter category directory is used to define the categories (such as position, velocity, acceleration, etc.) and corresponding dimensional units of the interface parameters in the simulation model; the model variable directory is used to define the interface parameter names, data types (such as integer, floating-point number, Boolean, string, enumeration, etc.), input / output types, and references to the interface parameter categories defined in the parameter category directory. Furthermore, a note item is configured under the parameter category directory. By adding a pre-set string describing the model parameter category in the note item, the simulation model interface parameters can be categorized without affecting the simulation model's compatibility with the FMI standard.

[0078] In this embodiment, step S2 may include the following sub-steps S21-S23:

[0079] S21. Generate model parameter category description information of the simulation model according to the 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.

[0080] Furthermore, model entity parameters are primarily used to describe the physical characteristics of simulation model entities (such as aircraft, vehicles, ships, and boats). These parameters, such as size, mass, center of gravity, center of buoyancy, and fluid dynamic parameters, are related to the inherent characteristics of a specific entity. Furthermore, when building a simulation system, model entity parameters can be defined in a separate data table. By changing these parameters, different specifications and models of the same entity model can be simulated without reprogramming the model.

[0081] Model mission parameters are primarily used to describe variable parameters during simulation tests, such as initial conditions, mission objectives, route planning, and mission environment parameters. When building a simulation system, these parameters can be defined differently using multiple parameter tables to enable multi-condition or multi-voyage simulation test management and batch processing.

[0082] Model signal interface parameters are mainly used for signal interfaces when assembling and connecting multiple simulation models, realizing multi-model interconnection and communication during simulation of complex large systems, and building a semi-physical simulation system.

[0083] S22. By controlling a pre-set 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.

[0084] S23. Add the model parameter category description information to the remarks item through the control automation tool to obtain a modified model description template file.

[0085] S3. Based on the modified model description template file and the obtained FMI standard model code file, a model description file containing model parameter category description information is generated.

[0086] 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 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.

[0087] In this embodiment, steps F1-F2 are further included before step S3:

[0088] F1. Obtain the model code source file and FMI standard header file of the simulation model.

[0089] F2. Convert the source code file into the FMI standard model code file based on the FMI standard header file.

[0090] 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 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.

[0091] 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.

[0092] In this embodiment, step S3 may include the following sub-steps S31-S33:

[0093] S31. Parse the FMI standard model code file to obtain FMI model information including interface parameter type, interface parameter quantity and model function prototype.

[0094] 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.

[0095] S33. Classify the interface parameters in the initial model description file according to the FMI standard to obtain a model description file containing model parameter category description information.

[0096] S4. Compile the FMI standard model code file according to the obtained system environment information for the simulation model to generate a binary dynamic library of the simulation model suitable for the specified system environment.

[0097] 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.

[0098] In this embodiment, step S4 may include the following sub-steps S41-S43:

[0099] S41. Obtain system environment information for the simulation model to perform simulation operation.

[0100] S42. Determine a compiler for compiling the content of the FMI standard model code file according to the system environment information.

[0101] S43. Calling a compiler to compile the model code file of the FMI interface standard to generate a binary dynamic library of the simulation model suitable for the specified system environment.

[0102] The compiler is either VS compiler or GCC compiler.

[0103] S5. According to the FMI standard model directory structure, the model description file, model code file, binary dynamic library and the obtained simulation model description file are packaged to form a deployable target simulation model file.

[0104] In this embodiment, step S5 may include the following sub-steps S51-S54:

[0105] S51. Obtain a description file of the simulation model, and obtain 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.

[0106] S52. Create a folder according to the directory structure of the FMI standard.

[0107] 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.

[0108] S54 , compressing the target simulation model file package to obtain the target simulation model file, thereby completing the packaging of the reusable simulation model.

[0109] In a specific embodiment, the simulation model packaging method based on the FMI standard described in steps S1-S5 above is used to package the underwater unmanned underwater vehicle 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. In addition, parameterized test plans can be managed and run by establishing different task parameter tables (such as different waypoint planning, etc.). Figure 2 As shown, the specific packaging process is:

[0114] (2) In response to the requirement information encapsulated in the underwater unmanned submersible simulation model UUV.mdl, create a model parameter category description template file (fmi2TypeDefinition.xsd) and a model description template file (fmi2ModelDescription.xsd).

[0115] (3) Through the script program, set the remark item under the parameter category directory of the model description template file, and add the model parameter category description information to the remark item to complete the modification of the model description template file.

[0120] (4) Use the Simulink Embedded Coder code generation tool to call the code generation template to generate the FMI standard model code file of the underwater unmanned submersible simulation model.

[0121] (5) Based on the model parameter category description template file (fmi2TypeDefinition.xsd) and the modified model description template file (fmi2ModelDescription.xsd), combined with the FMI standard model code file, the model description file of the underwater unmanned submersible simulation model is generated.

[0122] (6) According to the underwater unmanned submersible simulation platform, the FMI standard model code file is compiled using the GCC compiler to generate a win64 .dll binary dynamic library and a Linux64 .so binary dynamic library.

[0123] (7) According to the FMI standard model directory structure, the model description file, model code file, binary dynamic library and model description file of the underwater unmanned submersible simulation model UUV.mdl are packaged and compressed into a ZIP package. The suffix of the compressed package file name is changed to .fmu to obtain the UUV.fmu model.
