Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application.

An embodiment of the present application provides a simulation scheme, and a system simulation method of the present application is described below with reference to fig. 1, where, as shown in fig. 1, the method may include:
step S100, determining at least one virtual model selected by a user, wherein the virtual model is a model obtained by optimizing an initial virtual model by taking an operation result obtained by respectively carrying out simulation operation on the same data by the initial virtual model and a physical model as an optimization target, the physical model is a physical object under a system to be simulated, and the initial virtual model is a model which is built in advance based on the physical model.
Specifically, the system to be simulated is a simulated object, and various physical objects, such as a motor, a controller, a turntable or other hardware devices, are included under the system to be simulated. The simulation is to simulate the behavior of a real object under the system to be simulated by constructing a virtual model, so as to simulate the system to be simulated. In order to simulate a real object, an initial virtual model is constructed in advance based on the real object model. When the initial virtual model is built, certain nonlinear, time-varying or other complex properties may be ignored, which may cause a certain difference between the initial virtual model and the corresponding actual physical model, for example, there is a virtual model simulating CAN bus communication, and the virtual model simulating CAN bus communication may cause a difference from the actual CAN bus because the problems of delay, period fluctuation, frame loss, external interference and the like of CAN bus communication are not considered. The initial virtual model and the corresponding actual physical model have certain difference, which can lead to inaccurate operation results obtained by simulation operation of the initial virtual model, and when the initial virtual model and the physical model perform data interaction, the physical model performs corresponding operations after receiving data, such as adjusting the voltage of a motor, changing the rotation angle of a turntable, and the like, and the physical model can be damaged after the data exceeds the bearing range, such as burning the motor when the input voltage of the motor is overlarge. Therefore, after the initial virtual model is created based on the physical model, the operation results obtained by respectively carrying out simulation operation on the same data by the initial virtual model and the physical model are consistent as optimization targets, the initial virtual model is optimized to obtain the virtual model, and a user can select at least one virtual model so as to construct the selected at least one virtual model as a simulation project to carry out a simulation experiment.

And step S110, responding to the operation that the user constructs at least one virtual model as a simulation project, and obtaining a constructed target simulation project.
Specifically, after the user selects at least one virtual model, the at least one virtual model may be constructed as a simulation item, for example, a corresponding port and a bus are added to the selected virtual model, and a connection relationship between the virtual models is established by using the port and the bus. According to the embodiment of the application, the operation that the user constructs the selected at least one virtual model as the simulation project can be responded, and the target simulation project constructed by the user can be obtained, so that a simulation experiment can be executed based on the simulation project constructed by the user. The embodiment of the application can provide an interface for constructing the simulation project for a user to construct at least one virtual model into the simulation project in the interface.

Specifically, the operation that at least one virtual model is constructed as a simulation project is responded by a user, after a constructed target simulation project is obtained, a simulation experiment is executed based on the target simulation project, so that simulation is completed, and a simulation result is obtained. And executing a simulation experiment based on the target simulation project, namely driving the models in the target simulation project to perform data interaction and simulation operation.

In this embodiment of the present application, a process of optimizing an initial virtual model to obtain a virtual model is introduced by using an operation result obtained by performing a simulation operation on the same data by using the initial virtual model and a physical model, respectively, as an optimization target, where the process may include:
and step S01, driving the initial virtual model and the physical model to respectively perform simulation operation on the same data.
Optionally, the method may drive other preset virtual models to perform data interaction and simulation operation with the initial virtual model or the physical model, and send data received by the initial virtual model to the physical model in a process of performing data interaction between the other virtual models and the initial virtual model so as to perform simulation operation on the received data by the physical model, or send data received by the physical model to the initial virtual model in a process of performing data interaction between the other virtual models and the physical model so as to perform simulation operation on the received data by the initial virtual model.

And S03, taking the initial virtual model as a virtual model.
Specifically, since the operation results corresponding to the initial virtual model and the physical model are the operation results obtained by performing the simulation operation on the same data respectively, when the operation results corresponding to the initial virtual model and the physical model are identical, there is no difference between the initial virtual model and the physical model, and therefore the initial virtual model is used as the virtual model.
And step S04, optimizing the initial virtual model based on the operation results corresponding to the initial virtual model and the physical model.
Specifically, when the operation results corresponding to the initial virtual model and the physical model are inconsistent, a difference exists between the initial virtual model and the physical model, so that the initial virtual model is optimized based on the operation results corresponding to the initial virtual model and the physical model, and the virtual model and the physical model which are finally optimized do not have the difference.
