Research Of Interface Technology For Multi-Source Model Resource Joint Test Platform

HIT has developed the HIT-Joint Test Platform(H-JTP)to combine resources with different functions and geographical locations to simulate complex combat and test environments and complete the testing tasks of weapons and equipment.Test resources are the basis for building a joint test system.In the joint test construction task,various virtual,installed,and constructed resources need to be introduced.These resources are built by a large number of mathematical models.The widely used simulation platforms MATLAB,Simulink and the mathematical statistics platform SPSS have accumulated a large number of mature models after many years of accumulation.In order to introduce these heterogeneous models into the H-JTP platform,it is urgent to develop a multi-source model.Joint test platform resource packaging tool.Through the research on the operation mechanism of MATLAB and Simulink simulation model,it is proposed to adopt the mixed programming method and use MATLAB Engine as the control interface to realize the control of the running state of MATLAB and Simulink model.The information interaction between the joint test platform and the MATLAB model is realized by using the MATLAB library function,and the information interaction with the Simulink model is realized by sharing the memory.A simple model of a single Simulink module is translated into a dynamic link library file(DLL)available to the platform using the RTW tool.For the SPSS statistical model,the SPSS data processor control interface conversion software based on JAVA is proposed.The control program controls the operation of the processor with the spssjavaplugin.jar interface.At the same time,the JNI interface interacts with the joint test platform to obtain control commands.Aiming at the specificity of the SPSS model output result format,it is proposed to realize data interaction by sharing files.Based on the research of the above three model interface specifications,the resource encapsulation methods of each model are proposed,and the model encapsulation tools are developed based on these methods.Support joint testers to encapsulate existing simulation models and statistical models,transform the model into experimental resources,and realize the introduction of heterogeneous model resources.Finally,using the packaging tool,the atmospheric simulation model,the aerodynamics simulation model,the data analysis statistical model,etc.are packaged to generate the corresponding resource components.The joint test system is built by means of the H-JTP platform,and the aerostat model is in a complex atmosphere.Test the working status in the environment.The results show that each model packaging tool can work normally,and it can assist the joint testers to quickly build test resources and complete joint experiments.
