For the complex flow of inquiring and establishing a model and manually configuring parameters step by step to perform dynamic simulation in the related technology, the application establishes a simulation test platform to realize the simulation test method of the application, and the basic implementation part receives user instructions by the simulation test platform, converts the user instructions into C/C++ API information and completes interactive operation by a simulation engine; since the GUI design operation page is not applicable to the whole field, the approach is not adopted, and the application does not limit the field of model simulation.
The first embodiment of the application relates to a simulation test method. The specific flow is shown in figure 1.
Step 101, importing a basic model of a project to be simulated in modeling software through a simulation engine;
Step 102, obtaining parameter information of the item to be simulated from a parameter file of the item to be simulated, wherein the parameter information comprises: model parameters and simulation parameters;
step 103, generating a dynamic simulation model of the project to be simulated according to the model parameters and the basic model;
104, dynamically simulating the item to be simulated according to the simulation parameters and the dynamic simulation model;
Step 105, export the result of dynamic simulation and turn off the simulation engine.
In the embodiment, the basic model is imported through the simulation engine, so that the time for manually searching the basic model in the system folder is reduced; and the target parameter information is stored in the form of a parameter file, and can be directly read in the process of generating the dynamic simulation model of the project to be simulated without gradually inputting parameters manually, so that the parameter configuration process in the dynamic simulation process is optimized, the whole simulation test flow of the dynamic simulation model of the project to be simulated is more reasonable, the time and labor investment in the simulation test process are reduced, and the user experience is improved.
The implementation details of the simulation test method of the present embodiment are specifically described below, and the following is merely provided for facilitating understanding, and is not necessary to implement the present embodiment.
In step 101, a base model is imported by a simulation engine. In one example, the simulation engine is a MATLAB engine, and the basic model in the Simulink is searched and imported by the MATLAB engine to perform a simulation test flow. For example, when the import model is executed in the concrete implementation process, the MATLAB engine is opened through engOpen functions in the C/C++ environment, and the load_system function calls the basic model in the Simulink. In one example, if multiple base models need to be operated, after the multiple base models are imported, they are classified, so that the subsequent selection and searching of the base models are facilitated.
In one example, prior to importing the base model by the simulation engine, custom naming is performed in advance for the dynamic simulation model of the item to be simulated that is to be generated.
In one example, after importing the base model, the underlying constructs of the base model can be viewed through a simulation engine interface, e.g., the complete circuit connection relationships or component layout can be viewed through a MATLAB engine.
In addition, after the basic model is imported, in one example, whether a command window of the simulation engine needs to be displayed on the current operation interface is selected, and if so, the data processing process through the simulation engine can be observed more specifically; if the current interface is not displayed, the current interface only displays the result of the calling process, and the current interface is more direct and clear. For example, the setting of whether the MATLAB command window is visible is implemented by a engSetVisible function.
In step 102, parameter information of the item to be simulated is obtained according to the parameter file of the item to be simulated, where the parameter information includes: model parameters and simulation parameters; in one example, the required parameter file can be searched by inputting the name of the parameter file of the item to be simulated; wherein the simulation parameters are for example: simulation step length and simulation duration. In one example, the parameter file is called by a set_parameter function in the concrete implementation process.
In one example, the model parameters and the simulation parameters do not have a forced association relationship, and the model parameters and the simulation parameters can be acquired at different times and selectively according to the needs.
In one example, the parameter file may be obtained by a method including, but not limited to: acquiring all parameter generation of the model by calling a MATLAB engine; reading from the portable storage medium; interaction by communicatively connected devices, acquisition, etc. When the parameter configuration is carried out subsequently, the model reads the parameter information from the existing parameter file.
In addition, the model parameters may include model parameters of an integrally stored dynamic simulation model of the item to be simulated, or model parameters stored modularly according to different parts of the dynamic simulation model of the item to be simulated. When the basic model is subjected to parameter assignment, the overall parameters of the dynamic simulation model for importing the items to be simulated are selected, so that the time for parameter configuration is greatly reduced; or only the model parameters of partial modules are imported, so that the partial module parameters of the dynamic simulation model of the to-be-simulated project of the dynamic simulation can be adjusted in a targeted manner.
In step 103, generating a dynamic simulation model of the item to be simulated according to the model parameters and the basic model; that is, the model parameter values obtained from the parameter file are given to the imported base model. In one example, when a dynamic simulation needs to be performed on a certain battery model, a basic model of the battery is obtained first, and then a set current 1.5A of a first period of the battery model, a set current 3A of a second period of the battery model, a set current 5A of a third period of the battery model, a set current 10A of a fourth period of the battery model, specific times 10S, 8S, 20S, 5S of switching between the segments, and the like are read through a parameter file, and model parameters are directly given to the basic model to generate the dynamic simulation model of the item to be simulated. The whole assignment is carried out through the imported model parameters, so that the process of carrying out gradual assignment on the required model parameters is optimized, and the time investment for assigning the model can be effectively reduced.
In step 104, the dynamic simulation model of the item to be simulated is dynamically simulated according to the simulation parameters. In step 102, the simulation parameters have been read through the parameter file, and in step 103, the dynamic simulation model of the item to be simulated has been generated, and in one example, the dynamic simulation model of the item to be simulated is invoked to perform dynamic simulation according to the simulation parameters. For example, the dynamic simulation process is implemented by calling simOut functions in the concrete implementation process.
In one example, the parameter change in the process can be displayed when the dynamic simulation is performed, preferably, the parameter of interest is marked before the dynamic simulation is performed, and only the change condition of the parameter of interest is displayed when the dynamic simulation is performed.
In addition, if some of the model parameters and/or simulation parameters stored in the parameter file are required to be not adapted in the dynamic simulation process, or some of the model parameters and/or simulation parameters stored in the parameter file are required to be missing, after the parameter information of the item to be simulated is obtained from the parameter file of the item to be simulated, a user instruction is received, and adaptive adjustment is performed on the model parameters and/or simulation parameters required to be adjusted. Optionally, the configuration information is not acquired by the parameter file, and the parameter configuration is performed by adopting autonomous input of a user. The adaptive adjustment or configuration of the parameters enables the dynamic simulation process to be closer to an ideal flow, and user experience is improved on the premise that simulation steps are simplified.
In one example, after the model parameters and/or the simulation parameters are adjusted, the adjusted model parameters and/or simulation parameters are completely derived, and as the adjusted model parameters and/or simulation parameters are more suitable for the dynamic simulation overall flow, the parameter file is updated, so that the next direct call is facilitated. Or selecting to keep the original version parameter file, storing the updated model parameters and/or simulation parameters as a new version of the parameter file, and selecting to use the original version parameter file or the new version parameter file for next call, for example, specific version distinction can be embodied on the naming of the parameter file.
In addition, after the model parameters and/or the simulation parameters are adjusted, only the changed parameter part can be derived, the occupied storage space is smaller, the model parameters and/or the simulation parameters are combined and adopted when the same configuration is needed, and the parameter configuration of the part is more flexible. In one example, the model parameters and/or simulation parameters are adjusted, and the changed parameter parts are marked, and then marked and unmarked parameter information is exported as a configuration file; when parameter acquisition is performed again, calling the configuration file without calling the parameter file, fixing the unmarked parameter part data, and only focusing on and adjusting the marked parameter part; the configuration file supports only focusing and adjusting the marking parameters, so that the parameters needing focusing can be more conveniently and accurately adjusted and compared, and the efficiency of simulation test is improved.
In step 105, the results of the simulation are exported and the simulation engine is turned off. After the simulation is completed, a simulation result is exported, so that the manual recording of simulation data is avoided; in one example, closing the simulation engine MATLAB may be implemented by a engClose function.
In one example, when the simulation result is exported, all the information of the current simulation is exported completely, including the configuration of the dynamic simulation model, model parameters, simulation parameters and the like of the project to be simulated, so as to multiplex the current simulation process when needed.
In addition, a model description document is generated in the process of performing simulation test, wherein the presentation comprises: model name, MATLAB version, creator, creation time, last modifier, last modification time, remark description information, parameter file information of simulation project or model subsystem hierarchical structure, and the like, and is convenient for an operator to inquire configuration sources of the related nodes.
According to the embodiment, the basic model is imported through the simulation engine, so that the time for manually searching the basic model in the system folder is reduced; the configuration information is stored in the form of a parameter file, the parameter can be directly read in the process of generating a dynamic simulation model of a project to be simulated, the parameter is not required to be manually input step by step, the parameter configuration process in the dynamic simulation is optimized, meanwhile, a user is not excluded from adaptively adjusting model parameters or simulation parameters according to actual needs, and the adjusted parameter information is exported and used for updating the parameter file, so that the parameter is convenient to call subsequently; and custom naming is carried out on the generated dynamic simulation model and parameter file of the item to be simulated, so that searching can be more accurately and rapidly carried out when the dynamic simulation model and the parameter file are called again. The whole simulation test flow of the dynamic simulation model of the project to be simulated is more reasonable, the time and labor investment in the simulation test process are reduced, and the user experience is improved.
A second embodiment of the application relates to a simulation test method. The specific flow is shown in fig. 2.
Step 201, inquiring whether a dynamic simulation model of a project to be simulated exists in a preset model library; if not, go to step 202; if yes, go to step 206;
Step 202, importing a basic model of a project to be simulated in modeling software through a simulation engine;
step 203, obtaining model parameters of the item to be simulated from a parameter file of the item to be simulated;
step 204, generating a dynamic simulation model of the item to be simulated according to the model parameters and the basic model;
Step 205, exporting a dynamic simulation model of the item to be simulated, and storing the dynamic simulation model into a preset model library; and proceeds to step 207;
Step 206, calling a dynamic simulation model of the item to be simulated in the preset model library;
Step 207, obtaining simulation parameters of the item to be simulated from a parameter file of the item to be simulated, and performing dynamic simulation on a dynamic simulation model of the item to be simulated according to the simulation parameters;
and step 208, exporting the simulation result, and closing the simulation engine.
The steps 202, 204, 208 of the second embodiment are substantially the same as those of the first embodiment, and are not repeated here; since the requirements for parameter information are different in steps 203 and 207 with respect to the first embodiment, the simultaneous acquisition is not performed, and reference is made to the first embodiment for implementation details other than the acquisition order. The main differences are in step 201, step 206 and step 205, and the detailed process is described below.
In step 201 and step 206, inquiring whether a dynamic simulation model of the item to be simulated exists in a preset model library; that is, the local preset model library stores models for completing parameter configuration, and can be called through name inquiry when dynamic simulation is required. The process of importing a basic model into modeling software, acquiring model parameters in a parameter file and configuring a dynamic simulation model of a project to be simulated is not needed, the time for configuring the model before dynamic simulation is reduced, and the process of simulation test is further optimized.
In one example, the preset model library can store different versions of the dynamic simulation model of the same item to be simulated, and when the dynamic simulation model of the item to be simulated is obtained from the preset model library, the version of the dynamic simulation model of the item to be simulated, which is most suitable for the current simulation, is selected by comparing the model parameters, the connection structure and other information of the different versions. And displaying distinguishing marks on the parts of different versions, which are inconsistent in model parameters, on the interface for comparing model parameters, so that the differences of the different versions can be conveniently noted.
In addition, in a preset model library, model data are displayed in a classification tree form; when the dynamic simulation model of the item to be simulated is searched, the dynamic simulation model of the item to be simulated can be quickly searched through the classified tree structure besides searching through names.
In step 205, a dynamic simulation model of the item to be simulated is exported and stored in a preset model library. If the dynamic simulation model of the item to be simulated is not found in the preset model library, a basic model and a parameter file are acquired and used for constructing the dynamic simulation model of the item to be simulated; after the dynamic simulation model of the item to be simulated is built, the dynamic simulation model of the item to be simulated is exported and stored in a preset model library so as to be convenient to call when needed next time, reduce the step and time investment in generating the dynamic simulation model of the item to be simulated when the follow-up call is performed, and optimize the simulation test flow. Meanwhile, the export process is not limited to the process before step 207, and may be performed after the dynamic simulation model is generated, for example, step 207, and step 208 may be performed before, after, or at the same time, exporting and storing the generated dynamic simulation model.
In the embodiment, a preset model library is set on the basis that simulation parameters can be imported through a parameter file; model data for completing parameter configuration of a basic model of a project to be simulated is stored in a preset model library, so that the parameter configuration is convenient to directly call in the process of performing simulation test. If a dynamic simulation model of the item to be simulated exists in the preset model library, generating the dynamic simulation model of the item to be simulated by combining the basic model with model parameters in the parameter file; if the dynamic simulation model of the item to be simulated does not exist in the preset model library, the dynamic simulation model of the item to be simulated, which is generated by combining the basic model with the model parameters in the parameter file, is stored in the preset model library, so that the dynamic simulation model of the item to be simulated can be directly called when the dynamic simulation model of the item to be simulated is subjected to dynamic simulation, the step of configuring the model parameters is not needed, the simulation test process is further simplified, and the time investment for simulation test is reduced.
The above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they include the same logic relationship, and they are all within the protection scope of this patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.
