Examples
Referring to fig. 1 and 2, the invention discloses a semi-real-package simulation method combining measured data and simulation data, which is realized by the following steps.
1. Standardized data interface and functional component
The standardized data interface and the standardized functional components not only can realize the rapid custom assembly of the model, but also can access data and put into use after the model assembly is completed. Therefore, standardized configuration of the data interface and the functional components is a basis and premise for developing a semi-real-installation simulation method combining measured data with simulation data.
As shown in fig. 3 to 5, three types of data interfaces, i.e., an INPUT interface, an OUTPUT interface, and an OUTPUT interface, are defined, where the INPUT interface and the OUTPUT interface in a data module are respectively used as an INPUT interface and an OUTPUT interface of an assembly model, and are used for performing data interaction with other models in a simulation process, the OUTPUT interface in the data module and the function module are used as internal interfaces of the assembly model, and are used for performing data interaction between the data module and the function module, and interaction between different function modules can also be performed by means of the data module through the OUTPUT interface. * Interfaces represent a class of internal interfaces, such as gesture data interfaces, position data interfaces, on-off state interfaces, and the like.
The method comprises the steps of defining request modes, parameter submitting modes, request parameters, response parameters and the like of various interfaces such as an INPUT interface, an OUTPUT interface and the like, and naming and distinguishing the OUTPUT interfaces according to different names or IDs based on data content interacted by the OUTPUT interfaces. The interface types and numbers of different functional modules vary based on functional requirements. The data module's interface type covers all the function modules in the function module library.
2. Model generation
The method is based on the self-defined assembly of the data interface and the functional components, and can quickly generate the simulation model, which is an important link and content for developing simulation deduction. Model generation is mainly divided into two parts: and the digital model corresponds to the actual equipment and the simulation model is based on the simulation deduction requirement.
(1) The corresponding digital model is actually equipped. The model is based on real-time measurement data obtained by specific use of actual equipment in a simulation test scene, an association mapping relation from actual measurement data to equipment capacity to model functions is established by analyzing data content contained in the actual measurement data, functional components with corresponding functions are extracted for model assembly, a digital model corresponding to the actual equipment is generated, and the state and the display effect of the model are driven by the actual measurement data.
(2) And a simulation model based on simulation deduction requirements. The simulation model aims at carrying out blind supplement and improvement on the cooperative application capability of the existing equipment in the test verification scene, so that the simulation model is based on the analysis result of the efficiency evaluation data, a lower than expected link and capability improvement point are found through visual display effect graphs and analysis of the efficiency evaluation data, and the simulation model with the supplementary capability is quickly assembled and generated through a man-machine interaction mode and added into the test scene to participate in simulation.
3. Simulation deduction
The rapid development of computers, particularly high performance computers, provides many possibilities for ultra-real-time simulation deductions, by which hundreds of thousands or even hundreds of millions of repeated simulations and repeated deductions can be completed in the same time as the real world.
And building an integrated test environment and a system by combining the generated digital model and simulation model with the verification requirement of the simulation test.
The real-time digital model is driven by measured data, is mainly subjected to state change in the simulation deduction process, is generated based on evaluation data, is driven by a specific simulation scheme, and is set to change positions, speeds, states and the like according to the simulation scheme, so that capability supplement and lifting effects under different conditions can be evaluated later. Because of adopting standardized data interfaces, the addition and removal of the simulation model can not affect the whole simulation deduction process and data interaction.
In the simulation deduction process, parameters in a simulation scheme are configured and adjusted through a visual interface, and configuration and adjustment results are stored in a database in real time for analysis.
4. Efficacy assessment
The method combines actual equipment with a simulation system, and combines actual measurement data with simulation data to develop semi-real-package simulation, so as to verify the cooperative application capability of the actual equipment in an equipment system and the improvement effect of the addition of new equipment on the whole capability. The new equipment here refers to completely new equipment with different functions and capabilities that has not yet been delivered, or changes in number to existing equipment.
And establishing an evaluation index system based on a test verification scene, receiving simulation operation data generated by a simulation platform (system) in real time, performing efficiency evaluation, and outputting an evaluation result.
5. Capability feedback, adjustment optimization, and data storage
Semi-real simulations involving real equipment increase both the setup time and the test cost compared to pure digital simulations, and require more coordination and consideration. Therefore, in order to more fully utilize single test conditions, capability feedback and adjustment optimization based on an evaluation result are realized by continuously adjusting a simulation model and a simulation scheme, and by means of super-real-time simulation deduction, as many combination schemes as possible are verified.
The evaluation result is used for guiding the adjustment and optimization of the simulation model, namely, based on the analysis result of the evaluation data, the functional composition, the number and the like of the simulation model are adjusted and added into the joint simulation test.
The evaluation result is used for guiding the adjustment and optimization of the simulation scheme, namely, based on the analysis result of the evaluation data, the installation and deployment position, the on-off state, the running line direction and the like of the simulation model are configured and adjusted, and the scheme is updated in the joint simulation test.
The data storage is to store simulation operation data, performance evaluation data and the like into a data warehouse to support subsequent analysis of the disk.
Compared with the existing simulation method, the method of the invention mainly obtains the beneficial effects from the following three aspects: (1) The actual equipment is combined with the simulation model, and the actual measurement data is combined with the simulation data, so that the reliability and the reliability of the simulation result can be considered on the basis of improving the simulation efficiency and the effect, and the simulation model is more convincing; (2) The simulation model generated by the simulation system can be utilized to timely perform blind supplement in the scene test process under the condition that actual equipment participates, the promotion effect of the cooperative application capability of the equipment can be timely evaluated, and the modification and optimization of the scheduling planning scheme can be guided; (3) The simulation test process can be accelerated, and data support is provided for the development, production and application conversion of new equipment.
