[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0046] It should be understood that the order of execution of the steps in the following embodiments does not imply a precedence of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0047] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0048] The simulation system of a product equipment usually includes multiple simulation components that are mapped one-to-one to each structure of the product equipment. Each simulation component is used to simulate the node tasks of the structure it maps, thereby realizing a series of simulation tasks through a simulation module to test the complete performance of the product equipment. However, when the simulation system executes simulation tasks, the simulation component may have data output delays and it is difficult to accurately simulate the operation of the corresponding structure, resulting in low simulation accuracy and efficiency of the simulation system. Moreover, due to the output delay of the simulation component, it is easy to cause large differences in the simulation time steps between different simulation components connected to the same simulation component, that is, the time from different simulation components outputting simulation data to the same simulation component is inconsistent, which affects the data synchronization and exchange of each simulation component in the simulation system and reduces the simulation accuracy of the simulation system.

[0049] like Figure 1 As shown, a conventional simulation system includes simulation component A, simulation component B and simulation component C. After receiving their own input data, simulation component A and simulation component B perform simulation, obtain various simulation data and output them, wherein the simulation data output by simulation component A and simulation component B need to be input to simulation component C, so that simulation component C can perform node simulation according to the simulation data output by simulation component A and simulation component B. However, during the actual operation of the simulation system, there may be a delay in simulation component A and / or simulation component B. For example, it takes 1 second for simulation component B to run and output simulation data, while there is a delay in simulation component A to run and output simulation data, and the operation time may take 10 seconds, resulting in the inability of simulation component A and simulation component B to synchronously input the output data to simulation component C. The simulation time step of the two is quite different, which affects data synchronization and exchange, and reduces the simulation accuracy of the simulation system.

[0050] In view of the above problems, the control method of the simulation system provided by the embodiment of the present invention can be applied in Figure 2 In the control system shown in FIG. 1 , the control system includes a simulation system and a control device. The simulation system includes a plurality of simulation components, and the output data of the simulation component is the input data of the next simulation component connected to the simulation component. The control device communicates with each simulation component of the simulation system through a bus or a network.

[0051] Specifically, at least one simulation component in the simulation system is a target simulation component, and the target simulation component includes an original model and a simulation model of the original model. The original model of the simulation component is a simulation model of the actual structure in the product equipment. The simulation model of the original model is a model obtained by simulating the original model. The simulation model has the same function as the original model, and the model parameter amount of the simulation model is less than the model parameter amount of the original model. When the simulation system performs a simulation task, if the target simulation component receives input data from the outside or other simulation components, the control device controls the target simulation component in the simulation system to run the original model and the simulation model simultaneously, so that the original model and the simulation model are simulated according to the input data respectively, and the output data of the model with the shortest running time in the original model and the simulation model is used as the simulation data output by the target simulation component.

[0052] In one embodiment, a simulation system is provided, the simulation system comprising a plurality of simulation components, at least one of the plurality of simulation components being loaded with an original model and a simulation model having the same function as the original model, the model parameter amount of the simulation model being less than the model parameter amount of the original model. When the simulation system performs a simulation task, at least one simulation component is used to simultaneously run the original model and the simulation model for simulation, and is used to use the output data of the model that takes the shortest time to run between the original model and the simulation model as the simulation data output by the simulation component.

[0053] like Figure 3 As shown, the simulation system in this embodiment may include simulation component A, simulation component B and simulation component C. Simulation component A and simulation component B are respectively connected to simulation component C, and the simulation data output by simulation component A and simulation component B are used together as input data of simulation component C. Among them, simulation component A is a target simulation component including an original model and a simulation model of the original model; simulation component B and simulation component C both include the original model. Among them, the original model of simulation component A can be a model SimA that simulates the structure of a camera, and the simulation model of simulation component A can be a model f(x) obtained by simulating model SimA. When the simulation system performs a simulation task, if simulation component A receives input data from the outside or other simulation components, simulation component A runs model SimA and model f(x) at the same time, so that model SimA and model f(x) respectively simulate the camera function according to the input data, and the running time of model SimA and model f(x) is judged. If model f(x) outputs data before model SimA, model f(x) is the target model with short running time, and the data output by model f(x) is used as the simulation data output by simulation component A, and the simulation data of simulation component A is used as the input data of simulation component C. The delay of simulation component A output can be reduced or even eliminated, and the difference in simulation time steps between simulation component A and simulation component B can be reduced.

[0054] In the above embodiment, by constructing a simulation model with the same function as the original model and a smaller number of parameters, the simulation model can simulate the original model and has a faster running speed. When executing the simulation task, the target simulation component runs the original model and the simulation model at the same time, and uses the model output data with less time consumption as the output of the target simulation component. On the basis of ensuring the accuracy of the overall system output data, the delay of the simulation component output data can be effectively reduced, thereby improving the simulation efficiency and simulation accuracy of the simulation system. In addition, due to the reduction in the delay of the simulation component output data, the difference in simulation time steps between different simulation components is reduced, further improving the simulation accuracy of the simulation system.

[0055] In the simulation system, each simulation component can be implemented by different terminal devices or servers, and the control device can also be implemented by an independent electronic control unit or terminal device or server. In other examples, the control system can be a terminal device or a server, that is, the control device and each simulation component in the simulation system can be implemented by each functional module on the same terminal device or the same server. Among them, the terminal device includes but is not limited to various personal computers, laptops, smart phones, tablet computers and portable wearable devices. The server can be implemented by an independent server or a server cluster consisting of multiple servers.

[0056] In one embodiment, if Figure 4 As shown, a control method for a simulation system is provided, and the method is applied in Figure 1 The control system in is taken as an example to illustrate, including the following steps:

[0057] S10: When the simulation system executes the simulation task, the target simulation component is controlled to run the original model and the simulation model simultaneously for simulation.

[0058] It can be understood that the original model and the simulation model of the target simulation component have the same input data, which can be the output data of the upper-level simulation component of the target simulation component connected to the target simulation component, or the system input data (i.e., the input data of the simulation system) manually input by the user or input by an external device.

[0059] For example, the simulation system includes multiple simulation components, at least one simulation component in the simulation system is a target simulation component, and the target simulation component includes an original model and a simulation model of the original model. The simulation model has the same function as the original model, and the model parameter amount of the simulation model is less than the model parameter amount of the original model, so that the simulation model can simulate the original model and has a faster running speed.

[0060] It is understandable that, among the multiple simulation components, other simulation components (which may be referred to as ordinary simulation components) except the target simulation component include at least the original model. When the simulation system performs a simulation task, the other simulation components only run the original model. As an example, the other simulation components may include the original model, and may also include the simulation model, but for the other simulation components, even if the simulation model is included, the simulation system may only run the original model when performing a simulation task.

[0061] It can be understood that if all the simulation components among the multiple simulation components are target simulation components, the number of other simulation components is 0.

[0062] The target simulation component can be a first-level simulation node, an intermediate simulation node, or a last-level simulation node among multiple simulation components. If the target simulation component is a last-level simulation node, the output data of the target simulation component is the output result of the simulation system when the simulation system executes the simulation task.

[0063] If the target simulation component is a first-level simulation node or an intermediate simulation node, the simulation data output by the target simulation component is the input data of the next-level simulation component connected to the target simulation component. It can be understood that when the target simulation component is a first-level simulation node, its input data is the system input data manually input by the user or input by an external device; if the target simulation component is an intermediate simulation node, its input data is the simulation data output by the previous simulation node.

[0064] It is understandable that the simulation model loaded in the simulation system including the original model and the original model is the target simulation model. The other simulation components in the simulation system except the target simulation model are ordinary simulation models, and the ordinary simulation model at least includes the original model. The ordinary simulation model may include the original model, and may also include the simulation model, but the ordinary simulation model only runs the original model when the simulation system performs the simulation task.

[0065] S20: Using the output data of the model with the shorter running time between the original model and the simulation model as the simulation data output by the target simulation component.

[0066] When the simulation system performs a simulation task, if the target simulation component receives input data from the outside or other simulation components, the target simulation component is controlled to run the original model and the simulation model simultaneously, so that the original model and the simulation model can be simulated according to the input data respectively, and the output data of the model with the shorter running time among the original model and the simulation model is output as the simulation data of the target simulation component. Wherein, in the case that the simulation model outputs data before the original model, the output data of the simulation model is output as the simulation data of the target simulation component; in the case that the original model outputs data before the simulation model, or the original model and the simulation model output data at the same time, the output data of the original model is output as the simulation data output by the target simulation component.

[0067] When the simulation system executes a simulation task, each simulation component receives input data from the outside or the previous simulation component, and performs simulation according to the received input data until each simulation component completes the simulation, and finally one or more simulation components output the simulation data of the simulation task. When the simulation component only includes the original model, the simulation component is controlled to run the original model to execute the input data, and the output data of the original model is input as the simulation data of the simulation component to the next simulation component (if any) for node simulation, until all simulation components complete the node simulation, the simulation system completes the execution of the simulation task, and the final template simulation data is output. When the simulation component includes an original model and a simulation model of the original model, the simulation component (i.e., the target simulation component) is controlled to simultaneously run the original model and the simulation model to simulate according to the input data respectively, and the output data of the model with the shortest running time among the original model and the simulation model is used as the simulation data output by the target simulation component; wherein, if there is a next simulation component after the target simulation component, the simulation data output by the target simulation component is input to the next simulation component for node simulation until all simulation components complete the node simulation and the simulation system completes the execution of the simulation task; if there is no next simulation component after the target simulation component, i.e., the target simulation component is the last simulation component of the simulation system (i.e., the last level simulation node), the simulation data output by the target simulation component is directly used as the output result of the simulation system. wherein, since the model parameter amount of the simulation model is less than the model parameter amount of the original model, the simulation model can simulate the original model and has a faster running speed, the simulation data of the target simulation component is usually the data output by the simulation model, and the function of the simulation model is the same as that of the original model, so the outputs of the two are close or even the same, that is, the accuracy of the output of the simulation component is guaranteed, and the delay of the output of the simulation component is reduced.

[0068] In this embodiment, by constructing a simulation model with the same function as the original model and a smaller number of parameters, the simulation model can simulate the original model and has a faster running speed. When executing the simulation task, the target simulation component runs the original model and the simulation model at the same time, and uses the output data of the model with the shortest running time among the original model and the simulation model as the simulation data output of the target simulation component. On the basis of ensuring the accuracy of the output data of the overall system, the delay of the output data of the simulation component can be effectively reduced, thereby improving the simulation efficiency and simulation accuracy of the simulation system. In addition, due to the reduction in the delay of the output data of the simulation component, the difference in simulation time steps between different simulation components is reduced, further improving the simulation accuracy of the simulation system.

[0069] In one embodiment, in step S10, the output data of the model with the shortest running time among the original model and the simulation model is used as the simulation data output by the target simulation component, which specifically includes the following steps:

[0070] S11: After controlling the target simulation component to run the original model and the simulation model simultaneously, waiting to receive output data of the original model and the simulation model.

[0071] S12: When the output data of the simulation model is received and the output data of the original model is not received, the output data of the simulation model is used as the simulation data output by the target simulation component.

[0072] S13: When the output data of the original model is received and the output data of the simulation model is not received, or when the output data of the original model and the output data of the simulation model are received at the same time, the output data of the original model is used as the simulation data output by the target simulation component.

[0073] Specifically, when the simulation model outputs data before the original model, the output data of the simulation model is output as the simulation data of the target simulation component; when the original model outputs data before the simulation model, or the original model and the simulation model output data at the same time, the output data of the original model is output as the simulation data of the target simulation component.

[0074] Wherein, after the control device controls the target simulation component to run the original model and the simulation model at the same time, so that the original model and the simulation model perform node simulation according to the input data respectively, the control device will wait for receiving the output data of the original model or the simulation model to the input data. When the output data of the simulation model is received, and the output data of the original model is not received, that is, the simulation model outputs data before the original model, indicating that the operation time of the simulation model is shorter, the control device uses the output data of the simulation model as the simulation data output by the target simulation component. When the output data of the original model is received, and the output data of the simulation model is not received, that is, the original model outputs data before the simulation model, indicating that the operation time of the original model is shorter, the original model is determined to be the target model with short operation time, and the output data of the original model is used as the simulation data output by the target simulation component. When the output data of the original model and the output data of the simulation model are received at the same time, it means that the operation time of the two is the same, and the output data of the original model is directly used as the simulation data output by the target simulation component to improve the accuracy of the simulation data.

[0075] In this embodiment, after controlling the target simulation component to run the original model and the simulation model at the same time, it is necessary to wait for receiving the output data of the original model or the simulation model, wherein when the output data of the simulation model is received but the output data of the original model is not received, the output data of the simulation model is used as the simulation data output by the target simulation component; when the output data of the original model is received but the output data of the simulation model is not received, or when the output data of the original model and the output data of the simulation model are received at the same time, the output data of the original model is used as the simulation data output by the target simulation component. The specific process of outputting the data output by the target model with a short running time as the simulation data of the target simulation component is refined, and the output delay of the target simulation component is reduced.

[0076] In other embodiments, after controlling the target simulation component to run the original model and the simulation model simultaneously, the control device needs to perform timing while waiting to receive the output data of the original model or the simulation model; when the timing duration is greater than the calibrated running duration of the target simulation component, it indicates that the target simulation model has timed out, and it is necessary to re-control the original model and the simulation model of the target simulation model to run simultaneously, so as to re-simulate according to the input data until the simulation task is completed. Alternatively, when the timing duration is greater than the calibrated running duration of the target simulation component, it is necessary to re-control the original model and the simulation model of the target simulation model to stop running, and generate a re-running instruction for the simulation task of the simulation system, so that the simulation system responds to the re-running instruction and re-executes the simulation task, that is, it is necessary to control each simulation model in the simulation system to re-simulate the node until the simulation task is completed. It can reduce the situation where the simulation accuracy of the simulation system is low due to the timeout of the target simulation component.

[0077] Among them, within the calibrated running time of the target simulation component, when the output data of the simulation model is received but the output data of the original model is not received, the output data of the simulation model is output as the simulation data of the target simulation component; when the output data of the original model is received but the output data of the simulation model is not received, or when the output data of the original model and the output data of the simulation model are received at the same time, the output data of the original model is output as the simulation data of the target simulation component. The running time of the target simulation component is limited, and the simulation data is output only within the running time limit, which further reduces the output delay of the target simulation component, thereby further improving the simulation accuracy and simulation efficiency of the simulation system.

[0078] In one embodiment, if Figure 6 As shown, after step S20, that is, after the output data of the model with the shortest running time among the original model and the simulation model is used as the simulation data output by the target simulation component, the method further includes the following steps:

[0079] S20: after receiving the output data of the original model and the output data of the simulation model, performing consistency check on the output data of the original model and the output data of the simulation model;

[0080] After using the output data of the model with shorter running time among the original model and the simulation model as the simulation data output by the target simulation component, it is necessary to continue waiting to receive the output data of the model that has not output data (which may be the original model or the simulation model) until the output data of the original model and the output data of the simulation model are received.

[0081] After receiving the output data of the original model and the output data of the simulation model, it is necessary to perform a consistency check on the output data of the original model and the output data of the simulation model, so as to execute control logics of different simulation systems according to the consistency check result.

[0082] S30: If the output data of the original model is consistent with the output data of the simulation model, then the output result of the simulation system is obtained after the simulation system successfully executes the simulation task.

[0083] Among them, if the output data of the original model of the target simulation component is consistent with the output data of the simulation model, when there is no next simulation component after the target simulation component, that is, the target simulation component is the last simulation component in the simulation system, it is judged that the simulation system has successfully executed the simulation task, and the simulation data output by the target simulation component is used as the output result of the simulation system; when there is a next simulation component after the target simulation component, that is, the target simulation component is not the last simulation component in the simulation system, the simulation component after the target simulation component is controlled to perform simulation according to the simulation data of the target simulation component until the simulation system successfully executes the simulation task and obtains the output result of the simulation system.

[0084] S40: If the output data of the original model is inconsistent with the output data of the simulation model, when the simulation data output by the target simulation component is the output data of the simulation model, the output data of the original model is output as the simulation data of the target simulation component, and when there is a simulation component after the target simulation component, the simulation component after the target simulation component is controlled to be re-simulated to obtain the output result of the simulation system.

[0085] If the output data of the original model of the target simulation component is inconsistent with the output data of the simulation model, when the simulation data previously output by the target simulation component is the output data of the simulation model, the control device needs to clear the simulation data of the target simulation component and the simulation data of the simulation component after the target simulation component, that is, discard the simulation data of the target simulation component and all the simulation components after it. Then, if there is no next simulation component after the target simulation component, that is, the target simulation component is the last simulation component in the simulation system, it is judged that the simulation system successfully executes the simulation task, and at this time, the output data of the original model of the target simulation component is used as the simulation data output by the target simulation component to obtain the output result of the simulation system; if there is a next simulation component after the target simulation component, that is, the target simulation component is not the last simulation component in the simulation system, the output data of the original model is used as the simulation data of the target simulation component to be input to the next simulation component, and the simulation component after the target simulation component in the simulation system is controlled to re-simulate until the simulation system successfully executes the simulation task and obtains the output result of the simulation system. When the output data of the original model of the target simulation component is inconsistent with the output data of the simulation model, only the simulation component whose simulation data may be erroneous is controlled to re-output, which can not only ensure the accuracy of the final simulation data, but also reduce the time spent on re-running the simulation components that have been simulated but whose simulation data is not erroneous, further improving the simulation efficiency of the entire simulation system.

[0086] In other embodiments, if the output data of the original model is inconsistent with the output data of the simulation model, and the simulation data output by the target simulation component is the output data of the simulation model, if there is no next simulation component after the target simulation component, that is, the target simulation component is the last simulation component in the simulation system, it is judged that the simulation system has successfully executed the simulation task. At this time, the output data of the original model of the target simulation component is used as the simulation data output by the target simulation component to obtain the output result of the simulation system; if there is a next simulation component after the target simulation component, that is, the target simulation component is not the last simulation component in the simulation system, the control device needs to control the simulation system to re-execute the simulation task, that is, based on the same system input data, control each simulation component in the simulation system to re-simulate until the simulation system successfully executes the simulation task, so as to obtain the output result of the simulation system and ensure the accuracy of the final simulation data.

[0087] In other embodiments, if the output data of the original model is consistent with the output data of the simulation model, there is no need to control the simulation module of the simulation system to re-simulate. When there is no next simulation component after the target simulation component, that is, the target simulation component is the last simulation component in the simulation system, it is judged that the simulation system has successfully executed the simulation task, and the simulation data output by the target simulation component is used as the output result of the simulation system; when there is a next simulation component after the target simulation component, that is, the target simulation component is not the last simulation component in the simulation system, the simulation component after the target simulation component is controlled to simulate according to the simulation data of the target simulation component, until the simulation system successfully executes the simulation task and obtains the output result of the simulation system.

[0088] In this embodiment, after the output data of the model with shorter running time between the original model and the simulation model is output as the simulation data of the target simulation component, after receiving the output data of the original model and the output data of the simulation model, the output data of the original model and the output data of the simulation model are checked for consistency; if the output data of the original model and the output data of the simulation model are inconsistent, when the simulation data output by the target simulation component is the output data of the simulation model, the output data of the original model is output as the simulation data of the target simulation component, and when there is a simulation component after the target simulation component, the simulation component after the target simulation component is controlled to be re-simulated to obtain the output result of the simulation system; on the one hand, the accuracy of the simulation data output by each simulation module is improved, thereby improving the simulation accuracy of the entire simulation system; on the other hand, the time spent on re-running the simulation component that has been simulated but has no errors in the simulation data can be reduced, further improving the simulation efficiency of the entire simulation system.

[0089] In one embodiment, if Figure 7 As shown, before step S10, that is, before the simulation system executes the simulation task, the method further includes the following steps:

[0090] S01: obtaining a simulation model of a first simulation component among multiple simulation components, where the simulation model is trained based on historical operation data of an original model in the first simulation component;

[0091] S02: Load the simulation model into the first simulation component, and update to obtain a target simulation component including the original model and the simulation component.

[0092] Before the simulation system performs a simulation task, the control device needs to obtain a simulation model of a first simulation component (i.e., a simulation component that needs to be updated) among multiple simulation components, wherein the simulation model is trained based on the historical operation data of the original model in the first simulation component. For example, the historical operation data of the original model includes the historical input data of the original model and the historical output data corresponding to the historical input data, i.e., the data output by the original model after simulation based on the historical input data; the preset model is trained based on the historical input data and the historical output data of the original model until the preset model converges (e.g., the data output by the preset model based on the historical input data is similar or identical to the historical output data), and a simulation model with the same function and similar performance as the original model is obtained. Among them, the model parameter amount of the preset model is less than the model parameter amount of the original model; the preset model can be a Convolutional Neural Network (CNN) model.

[0093] After obtaining the simulation model of the first simulation component, the simulation model of the original model in the first simulation component is loaded into the first simulation component, and the target simulation component including the original model and the simulation component is updated to reduce the output delay of the target simulation component when the subsequent simulation system performs simulation tasks, thereby improving the simulation accuracy and efficiency of the simulation system.

[0094] In this embodiment, before the simulation system performs a simulation task, it is necessary to obtain a simulation model of a first simulation component among multiple simulation components, and the simulation model is trained based on the historical operation data of the original model in the first simulation component, and then the simulation model is loaded into the first simulation component, and the target simulation component including the original model and the simulation component is updated. The corresponding simulation model is trained based on the historical operation data of the original model in the simulation component, so that the simulation model has the same function and similar performance as the original model, which can improve the similarity between the simulation model and the original model, thereby improving the accuracy of the simulation data output by the simulation module, and further improving the simulation accuracy of the entire simulation system.

[0095] In one embodiment, before step S01, that is, before obtaining the simulation model of the first simulation component, the method also includes the following steps: taking all the simulation components in the simulation system as the first simulation components, and updating the simulation model of the original model in each simulation component to each simulation component, the output delay of each simulation component can be effectively reduced, thereby improving the simulation efficiency of the entire simulation system.

[0096] In one embodiment, before step S01, that is, before obtaining the simulation model of the first simulation component, the method further includes: taking a simulation component whose running time is greater than or equal to the calibrated running time of the corresponding simulation component among the multiple simulation components as the first simulation component. In addition, a simulation component whose running time is greater than or equal to the calibrated running time of the corresponding simulation component among the multiple simulation components can also be taken as the first simulation component.

[0097] The calibration operation time can be calibrated based on experience, and the calibration operation time of different simulation components is different. To improve data accuracy, the calibration operation time can be the operation time of the real structure in the product equipment corresponding to the simulation component; or the calibration operation time can be the maximum operation time limited by the real structure.

[0098] Specifically, it is necessary to take the average running time (or minimum running time) of the simulation component in the simulation system during the historical simulation running process as the running time of the simulation component, and determine the running time of the real structure in the product equipment corresponding to the simulation component; take the running time of the real structure as the calibrated running time of the simulation component, and determine whether the running time of the simulation component is greater than the calibrated running time of the simulation component, or determine whether the ratio of the running time of the simulation component to the calibrated running time is greater than a preset ratio; if the running time of the simulation component is greater than or equal to the calibrated running time of the simulation component, or the ratio of the running time of the simulation component to the calibrated running time is greater than or equal to the preset ratio, then the simulation component is taken as the first simulation component.

[0099] In the present embodiment, a simulation component among multiple simulation components whose running time is greater than or equal to the calibrated running time of the corresponding simulation component is used as the first simulation component, so that the simulation model of the simulation component with high running time can be subsequently updated to this simulation component, while the simulation components with less running time delay do not need to be updated. On the basis of ensuring the simulation efficiency of the entire simulation system, the data loading amount of the simulation model can be reduced and the system overhead can be reduced.

[0100] In one embodiment, the historical operation data of the original model includes the historical input data and historical output data of the original model, and the historical operation time of running the historical input data to obtain the historical output data. Before step S01, it is necessary to train the simulation model of the original model according to the historical operation data of the original model in the first simulation component, so as to facilitate subsequent loading and updating to the simulation module. The simulation model is trained in the following manner:

[0101] S011: Determine multiple training samples based on multiple historical operation data of the original model.

[0102] When training a simulation model, it is necessary to obtain multiple historical operation data of the original model in the simulation component, and the historical operation data of the original model includes the historical input data, historical output data, and the historical operation time of running the historical input data to obtain the historical output data. Then, multiple training samples are determined based on the multiple historical operation data of the original model, wherein each training sample includes the historical input data, the historical output data corresponding to the historical input data, and the historical operation time.

[0103] S012: Train the preset model according to multiple training samples to obtain a simulation model.

[0104] After obtaining a plurality of training samples, the preset model is trained according to the plurality of training samples to obtain a simulation model, wherein the model parameter quantity of the preset model is less than the model parameter quantity of the original model. That is, according to the historical input data, historical output data, and the historical operation time of running the historical input data to obtain the historical output data of the original model, the preset model is trained to obtain a simulation model, and the time required for the simulation model to simulate according to the historical input data (i.e., the operation time) must be less than the historical operation time corresponding to the historical input data, which can improve the simulation operation speed of the simulation model.

[0105] Specifically, the historical input data in the training sample is input into the preset model for calculation to obtain simulation output data. According to the simulation output data, the historical output data corresponding to the historical input data, and the historical running time, it is determined whether the preset model meets the convergence conditions. When the preset model does not meet the convergence conditions, the preset model is continued to be iteratively trained based on the training sample until the preset model meets the convergence conditions, and the output converged preset model is the simulation model.

[0106] Among them, the convergence condition may include that the operation time of the preset model is less than the historical operation time, which can reduce the operation efficiency of the simulation model of the subsequent convergence output and reduce the output delay of the simulation component. The convergence condition may also include that the similarity between the simulation output data of the preset model and the corresponding historical output data is greater than a preset value (such as 70%). The higher the model similarity, the larger the data volume of the model parameters. On the basis of ensuring the simulation accuracy of the simulation model of the subsequent convergence output, the model parameter volume of the simulation model can be reduced, and the model training data volume can also be reduced to improve the model training efficiency.

[0107] In this embodiment, multiple training samples are determined based on multiple historical operation data of the original model, and the training samples include historical input data, historical output data corresponding to the historical input data, and historical operation time; the historical input data in the training samples are input into the preset model for calculation to obtain simulation output data; based on the simulation output data, the historical output data corresponding to the historical input data, and the historical operation time, it is determined whether the preset model meets the convergence condition, and the convergence condition at least includes that the operation time of the preset model is less than the historical operation time; when the preset model does not meet the convergence condition, the preset model continues to be iteratively trained based on the training samples until the preset model meets the convergence condition, and the converged preset model is output as the simulation model. The training process of the simulation model is clarified, and on the basis of ensuring the simulation accuracy of the simulation model outputted by the subsequent convergence, the amount of model parameters of the simulation model is reduced, and the amount of model training data can also be reduced to improve the model training efficiency.

[0108] In other embodiments, the convergence condition may also include: the similarity between the simulation output data of the preset model and the corresponding historical output data is greater than a preset value (such as 70%); the operation time of the preset model is less than the historical operation time, and is close to the operation time of the real structure corresponding to the simulation component where the original model is located, that is, the difference between the operation time of the preset model and the operation time of the corresponding real structure is less than the preset difference. This makes the operation time of the simulation model in the simulation component close to the operation time of the real structure, further reducing the output delay of the simulation component.

[0109] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
