Design Of Intergrated Information Display Software For Joint Test Platform

Based on the current status of virtual simulation,this paper studies the integrated information display software integrating geography environment,atmospheric environment and combat test equipment.This topic designs a battlefield situation display software for HDI-JTP architecture for two-dimensional scenes,HIT-JTP The structure is a support system for joint testing proposed by the Institute of Automation Test and Control of Harbin Institute of Technology.It allows the tester to visually view the test situation and support virtual environment display,special effects,analytical measurements and other functions.Based on the analysis of HIT-JTP architecture,the overall scheme of integrated information display software is given,and the specific functions of important modules are analyzed.Based on the overall plan,the key technologies of the software are discussed.Firstly,in order to realize the flexible association between the middleware data and the user-defined display scheme,the basis of the HIT-JTP architecture middleware operation mechanism is studied.The middleware interface function of the integrated information display software is written,and various displays are realized.In order to improve the scalability of display software,a three-dimensional display model driving method and an extension method are designed to support the arbitrary device model.In order to realize the pseudo display of the invisible virtual environment,the research is carried out.Exploring the principle of virtual environment display,designing the effects of wind field,temperature field,rain and snow,etc.,in order to observe the influence of environmental factors on the virtual test;for the battlefield situation analysis,in order to make the test personnel more intuitive observation of the combat situation,adopted The multi-view method performs situational display and uses dimensionality reduction to analyze battlefield situation.Secondly,the UML modeling language is used to describe the design of the integrated information display software,and the detailed requirements analysis,summary design and detailed design of the software are carried out.Complete the requirements analysis of the software,get the software use cases,and complete the software class diagram design.Finally,the two-dimensional scene module,three-dimensional scene module,middleware data interaction module and model driver module are tested.The test results show that the system architecture design,key technology exploration and software detailed design of the software are correct.
