Abstract: To solve the problems existing in the simulation training system such as large amount of work, low development efficiency and low quality, a design method of the simulation training system based on Virtools and HLA is put forward. After providing a design system structure of the anti-aircraft gun driving control system,four key technologies (development of RTI BB module, motion simulation, visual display, model physical zing and collision detection) are investigation. An operation simulation platform of a certain anti-aircraft gun driving control system was designed based on this method.Keywords: Virtools; distributed mutual simulation; high level architecture (HLA); driving control system; visual display

分布交互仿真技術(shù)從產(chǎn)生(SIMNET計(jì)劃)到DIS2.X,IEEE1278.X系列協(xié)議和ALSP協(xié)議,進(jìn)而發(fā)展到今天的HLA,都是為了解決建模與仿真(Modeling and Simulation,MS)領(lǐng)域存在的問題。如:絕大多數(shù)仿真平臺的應(yīng)用實(shí)現(xiàn)較為獨(dú)立;仿真平臺之間的互操作性和重用性差;開發(fā)、維護(hù)和使用費(fèi)時(shí)間,而且成本高;可驗(yàn)證性、有效性和置信度較差[1]。當(dāng)前,形式、功能單一的模擬訓(xùn)練系統(tǒng)已不能滿足部隊(duì)的需求,因此如何越好越快地設(shè)計(jì)出能夠面向全系統(tǒng)、全任務(wù)空間、全領(lǐng)域的模擬訓(xùn)練系統(tǒng)已成為當(dāng)前一個(gè)迫切需要解決的問題。
HLA就是從體系結(jié)構(gòu)上建立的這樣一個(gè)框架,它能盡量涵蓋MS領(lǐng)域中涉及各種不同類型的仿真系統(tǒng),并利于相互間的互操作和重用性,同時(shí)能夠利用不斷發(fā)展的新技術(shù)來滿足復(fù)雜大系統(tǒng)的仿真需求。采用HLA的技術(shù)體制,可以將單個(gè)仿真應(yīng)用連接起來組成一個(gè)大型的虛擬世界。……
