Description

Technical Field

[0001] The present invention relates to the field of data processing, and in particular to a method, device, electronic equipment and computer program product for importing a simulation model. Background Art

[0002] Simulation is a model-based activity used when system analysis methods cannot be used to obtain relevant information based on the system's mathematical model. Model-based simulation utilizes modern computer technology to digitally simulate the real world. It involves creating a virtual environment and system model, then performing numerical calculations and simulations on these models to simulate the system's behavior and performance.

[0003] Model-based simulation can be applied across a wide range of fields, including engineering, manufacturing, transportation, and healthcare. In engineering, it can be used to design, test, and evaluate various products and systems, such as robots, aircraft, automobiles, and rockets. In healthcare, it can be used to simulate the function of human organs to better understand disease progression and treatment options. In transportation, it can be used to simulate urban traffic flow and congestion, aiding in the development of transportation plans and policies.

[0004] Functional Mock-up Interface (FMI) is a tool for building model interactions. It's an open standard that enables collaboration between different simulation software and development tools. FMI allows models to be integrated into a common simulation environment, allowing different models to interact and run within the same simulation software. This saves time and costs and improves model repeatability and reliability.

[0005] In the actual FMI compatibility process, because different simulation software has different technical paths, implementation architectures, and solver algorithms, it is not necessarily possible to directly use the FMI standard interface.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0028] According to an embodiment of the present invention, an embodiment of a method for importing a simulation model is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Figure 1 is a flow chart of a method for importing a simulation model according to an embodiment of the present invention, such as Figure 1 As shown, the method includes the following steps:

[0030] Step S102: obtaining a simulation model to be imported, wherein the simulation model at least includes: an intermediate structure file for describing the internal working principle of the simulation model in a native environment;

[0031] Step S104: generating a description file that complies with the simulation standard required by the functional simulation interface based on the intermediate structure file, wherein the description file is at least used to indicate a conversion method for converting the internal working principle of the native environment into one that complies with the simulation standard;

[0032] Step S106, packaging the description file and the simulation model to obtain a functional simulation model unit, wherein the functional simulation model unit complies with the simulation standard;

[0033] Step S108 , in the simulation software, using the import function designed in advance according to the simulation standard to parse the functional simulation model unit, and adding the simulation model to the simulation software based on the parsed description file.

[0034] In an embodiment of the present invention, a simulation model to be imported is obtained, wherein the simulation model at least includes: an intermediate structure file for describing the internal working principle of the simulation model in a native environment; based on the intermediate structure file, a description file that meets the simulation standard required by the functional simulation interface is generated, wherein the description file is at least used to indicate a conversion method for converting the internal working principle in the native environment into one that meets the simulation standard; the description file and the simulation model are packaged to obtain a functional simulation model unit, wherein the functional simulation model unit meets the simulation standard; in the simulation software, the functional simulation model unit is parsed using an import function pre-designed according to the simulation standard, and the simulation model is added to the simulation software based on the parsed description file, thereby achieving the purpose of converting the internal working principle of the simulation model into a unified simulation standard, and importing simulation models in different native environments into the simulation software, thereby achieving the technical effect of compatibility with simulation models in different native environments, thereby solving the situation where the simulation model is imported based on the functional simulation interface FMI, and there is a technical problem of incompatibility between the functional simulation interface and the simulation model to be imported.

[0035] For example, when a power system model originally running in the Matlab / Simulink environment needs to be imported into a general system simulation software, the model's architecture, parameters, and algorithm logic can be recorded in detail by using a specific intermediate structure file (such as an XML description file); then, according to the requirements of the functional simulation interface, a description file is generated. This file contains information on how to map variables and functions in the native environment to the target simulation software. This process not only realizes the format conversion of the model, but also ensures the accurate and lossless transmission of the model functions; finally, by packaging and importing it into the simulation software, users can run and compare models from different native environments on a unified platform, greatly improving the efficiency and flexibility of cross-platform model reuse.

[0036] In addition, the above method is also applicable to various types of simulation models, including but not limited to mechanical, electronic, chemical and biological system models, further broadening its application scope.

[0037] In the above step S102, the intermediate structure file in the simulation model generally refers to the internal architecture of the model or the intermediate computing layer of the model, which is used to describe the internal working principle of the model, including the various components in the model, the connections between these components, and how they interact to simulate the behavior of the system.

[0038] In the above step S104, the functional simulation interface is Functional Mock-up Interface (FMI), and the simulation standard is the FMI standard.

[0039] In the above step S106 , the functional simulation model unit is a Functional Mock-up Unit (FMU).

[0040] As an optional embodiment, generating a description file that meets the simulation standards required by the functional simulation interface based on the intermediate structure file includes: obtaining a preset description file template, wherein the preset description file target at least describes a conversion method for converting the internal working principles in the native environment into one that meets the simulation standards; and converting the intermediate structure file into a description file according to the preset description text template.

[0041] In the above-mentioned embodiment of the present application, the use of a preset description file template greatly simplifies the description file creation process and ensures the accuracy and consistency of the conversion. Through this template, even users who are unfamiliar with the target simulation software can easily complete the conversion and avoid errors introduced by manually writing description files. This method not only improves the efficiency of model conversion, but also reduces the need for professional skills, thereby promoting the sharing and application of simulation models in a wider range of fields.

[0042] For example, when importing a vehicle dynamics model from the CarSim environment into other simulation software, the preset description file template can contain a set of standardized tags and attributes to describe the model's physical properties, input and output ports, and how it connects to other models.

[0043] This method is also applicable to architectural physics models, fluid dynamics models, etc. Its standardized conversion process ensures the accuracy and reliability of the model.

[0044] As an optional embodiment, packaging the description file and the simulation model to obtain a functional simulation model unit includes: placing the simulation model into a preset folder; using a preset compiler to compile the preset folder to generate a dynamic link library; packaging the description file and the dynamic link library to obtain a functional simulation model unit.

[0045] In the above embodiments of the present application, the process of packaging the simulation model and description file into a functional simulation model unit ensures the integrity and portability of the model. The simulation model and description file are packaged together to form a functional simulation model unit that can be directly recognized and loaded by the simulation software. This not only simplifies the deployment and management of the model, but also allows the model to run on different hardware and operating systems, improving the versatility and usability of the model. This packaging strategy is also applicable to robot kinematic models, signal processing models, etc. Its encapsulation helps protect the intellectual property rights of the model while promoting the efficient distribution and use of the model.

[0046] For example, a complex aircraft control model might contain a large amount of C / C++ code and detailed parameter configuration. Placing it in a preset folder and compiling it with a preset compiler (such as GCC) generates a dynamic link library (DLL) that encapsulates all the model's functionality while maintaining compatibility with the native environment.

[0047] As an optional embodiment, placing the simulation model into a preset folder includes: obtaining an interface file pre-configured for the simulation model, wherein the interface file supports a functional simulation interface; placing the interface file and the intermediate structure file into a preset folder, wherein the intermediate structure file can be called by the simulation software with the support of the interface file.

[0048] In the above embodiments of the present application, the configuration of the interface file is a key step to ensure that the model is correctly loaded and run. The interface file will guide the simulation software on how to correctly call the model to ensure that the model can run stably in the new environment. By including the interface file and the intermediate structure file in the preset folder at the same time, the model import process becomes more automated and reliable, reducing the need for human intervention and improving the success rate and efficiency of model import.

[0049] For example, for a Python-based machine learning model, a pre-configured interface file can define the model's input and output formats, required library file paths, and initialization and termination functions.

[0050] The configuration strategy of the above interface file is also applicable to models built in programming languages ​​such as Java and Rust. Its standardized interface definition helps the cross-platform compatibility of the model and promotes the integration and collaborative work of multidisciplinary simulation models.

[0051] As an optional embodiment, in the simulation software, an import function designed in advance according to the simulation standard is used to parse the functional simulation model unit, and the simulation model is added to the simulation software based on the parsed description file, including: in the simulation software, the functional simulation model unit is parsed using the import function to obtain a description file and a simulation model; the intermediate structure file in the simulation model is parsed using the description file to obtain variable information that meets the simulation standard, wherein the variable information is determined based on the variables that describe the working principle of the content of the simulation model in the native scenario; according to the variable information, the simulation model is added to the simulation software.

[0052] In the above-mentioned embodiment of the present application, the import function of the simulation software can automatically identify and load the model by parsing the functional simulation model unit. This process is based on the variable information recorded in the description file. In this way, even if there are differences between the native environment of the model and the target software, the core functions and parameters of the model can be accurately retained. This not only simplifies the model import process, but also ensures the accuracy and consistency of the model, providing a convenient model exchange and cooperation platform for experts in different fields.

[0053] For example, the description file of an electromagnetic field model native to ANSYS will list in detail all the variables in the model, including mesh size, material properties, boundary conditions, etc., and explain how these variables are mapped to the standard variables of the target simulation software.

[0054] The above technology is also applicable to importing CAD models, finite element models, etc. into general simulation software. Its automated variable mapping mechanism significantly improves the efficiency and accuracy of model import.

[0055] As an optional embodiment, after using the description file to parse the intermediate structure file in the simulation model to obtain variable information that meets the simulation standard, the method also includes: using the information configuration page to display the variable information; receiving the setting instructions of the variable information through the information configuration page; and updating the variable information based on the setting instructions.

[0056] In the above-mentioned embodiments of the present application, the introduction of the information configuration page enables users to intuitively view and adjust the parameters of the model, thereby enhancing the configurability of the model and the user experience. The setting instructions obtained through the information configuration page can update the variable information in the model in real time without recompiling the model, which greatly improves the speed of model debugging and optimization. It not only improves the convenience of model use, but also promotes the personalized customization of the model to meet the specific needs of different researchers and engineers.

[0057] For example, when simulating a complex climate model, the information configuration page can display key variables in the model, such as temperature, humidity, wind speed, etc., and allow users to adjust the values of these variables according to experimental requirements or hypothetical scenarios.

[0058] This technology is also applicable to economic models, ecological models, etc. Its dynamic parameter adjustment capability helps to deeply explore the behavior of the model under different conditions and promotes the development of simulation science.

[0059] As an optional embodiment, in the simulation software, after using the import function designed in advance according to the simulation standard to parse the functional simulation model unit, and adding the simulation model to the simulation software based on the parsed description file, the method also includes: combining the simulation model with the preset model through the simulation software to obtain a joint model, wherein the preset model meets the simulation standard; determining the combination relationship between the simulation model and the preset model in the joint model, wherein the combination relationship is at least used to indicate that the output end of the simulation model is connected to the input end of the preset model, or the output end of the preset model is connected to the input end of the simulation model; assigning priorities to the simulation model and the preset model according to the combination relationship, wherein when the output end of the simulation model is connected to the input end of the preset model, the priority of the simulation model is higher than the priority of the preset model, and when the output end of the preset model is connected to the input end of the simulation model, the priority of the preset model is higher than the priority of the simulation model; and calculating the simulation results of the simulation model and the preset model one by one in order of priority from high to low.

[0060] In the above-mentioned embodiment of the present application, the introduction of the information configuration page enables users to intuitively view and adjust the parameters of the model, thereby enhancing the configurability of the model and the user experience. The setting instructions obtained through the information configuration page can update the variable information in the model in real time without recompiling the model, which greatly improves the speed of model debugging and optimization. This method not only improves the convenience of model use, but also promotes the personalized customization of the model to meet the specific needs of different researchers and engineers.

[0061] For example, when simulating a complex climate model, the information configuration page can display key variables in the model, such as temperature, humidity, wind speed, etc., and allow users to adjust the values of these variables according to experimental requirements or hypothetical scenarios.

[0062] This technology is also applicable to economic models, ecological models, etc. Its dynamic parameter adjustment capability helps to deeply explore the behavior of the model under different conditions and promotes the development of simulation science.

[0063] The present invention also provides an optional embodiment, which provides a model encapsulation, import, calculation and joint simulation method based on the FunctionalMock-up Interface standard.

[0064] Figure 2 FIG. 1 is a schematic diagram of a method for generating a functional prototype unit and importing it into simulation software according to an embodiment of the present invention. Figure 2 As shown, the method includes the following steps:

[0065] Step S201 : determining a simulation model to be packaged, wherein the simulation model includes: a model body, an intermediate structure, and an interface file of a Functional Mock-up Interface (FMI).

[0069] Step S205 : According to the user's operation instruction, the description file and the dynamic link library file are packaged to obtain a Functional Mock-up Unit (ie, FMU).

[0070] In step S206, in the simulation software, the import function designed according to the Functional Mock-up Interface standard is used to parse the Functional Mock-up Unit content, add it to the calculation unit of the simulation software, and submit the underlying calculation as a whole.

[0071] The above-mentioned embodiments of the present application realize the encapsulation of user code into a Functional Mock-up Unit, wherein the Functional Mock-up Unit can be imported and run by simulation software, thereby realizing joint simulation of multiple simulations.

[0072] As an optional embodiment, a method for importing a functional prototype unit into simulation software includes the following steps:

[0073] Step S1: Generate a description file for the simulation model to be packaged.

[0075] Step S3: Pack the description file and the dynamic link library to obtain the FMU.

[0076] Step S4: Design the import function according to the FMI standard and import it into the simulation software.

[0077] Step S5: submit the bottom layer to perform simulation calculations in conjunction with other simulation models.

[0078] In the above step S1, the model file to be encapsulated (i.e., the simulation model) needs to include: the model body, intermediate structure and Functional Mock-up Interface interface of the simulation model. On this basis, the file template and intermediate structure described by the FMI standard are used to generate the intermediate structure file.

[0079] Figure 3 This is a schematic diagram of a method for importing a functional prototype unit into simulation software according to an embodiment of the present invention. Figure 1 ,like Figure 3 As shown, the specific process of the above step S4 includes:

[0081] Step S302, find the description file in the FMU, read the variable information of the simulation model from the description file, mainly read the name of the variable, the variable type used to determine whether the variable is a parameter, intermediate variable, input variable or output variable, and the data type of the variable.

[0082] Step S303: The read variable information is presented to the user. The user sets the value of the variable according to the information and selects the variable to be input or output (ie, determines the user code file).

[0083] In step S304, the user connects the output of other models to the input of the FMU, or connects the output of the FMU to the input of other models, to achieve joint operation of multiple solution models.

[0084] Figure 4 This is a schematic diagram of a method for importing a functional prototype unit into simulation software according to an embodiment of the present invention. Figure 2,like Figure 4 As shown, the specific process of the above step S5 includes:

[0085] Step S401 : Integrate the complete FMU model and other models into a new model.

[0086] Step S402 : Calculate the simulation priority according to the input and output connection relationship of the units in the new model.

[0087] Step S403 , the simulation results are calculated one by one according to the priority, wherein the units imported by the FMU call the dynamic link library to calculate the results, and the units inside the simulation software use their own methods to calculate the results.

[0088] Step S404: Select information required by the solver from the calculation results and provide it to the solver to advance the simulation.

[0089] In step S405, the solver determines whether the simulation has reached the end time. If so, the simulation ends; if not, the solver returns to step S402.
