【摘要】：隨著人類社會(huì)進(jìn)入知識(shí)經(jīng)濟(jì)時(shí)代,以及信息技術(shù)的高速發(fā)展,儀器儀表在各個(gè)領(lǐng)域都得到了日益廣泛的應(yīng)用,這也使得儀器儀表行業(yè)得到了快速的發(fā)展。然而,由于制作工藝的限制,傳統(tǒng)儀表在靈敏度、精確度、復(fù)現(xiàn)性、穩(wěn)定性等方面會(huì)受到一定影響。同時(shí),外界環(huán)境也會(huì)影響到儀表的可靠性。為了解決上述問(wèn)題,并且滿足現(xiàn)代科技對(duì)測(cè)控精度的更高要求,在計(jì)算機(jī)技術(shù)、虛擬現(xiàn)實(shí)技術(shù)與網(wǎng)絡(luò)通信技術(shù)等信息技術(shù)迅猛發(fā)展的基礎(chǔ)上,虛擬儀表應(yīng)運(yùn)而生,并受到了越來(lái)越多的關(guān)注與應(yīng)用。為了能夠使眾多類型的虛擬儀表能夠被方便快捷的開(kāi)發(fā),并且使非計(jì)算機(jī)專業(yè)人士也能夠完成虛擬儀表的設(shè)計(jì),本課題完成了可視化虛擬儀表設(shè)計(jì)平臺(tái)系統(tǒng)的設(shè)計(jì)與研發(fā)。該系統(tǒng)的特點(diǎn)在于能夠根據(jù)測(cè)試任務(wù)的實(shí)際需求,定義和設(shè)計(jì)出相應(yīng)的虛擬儀表;同時(shí),系統(tǒng)可以滿足普通用戶的需求,不要求使用者具備太多的計(jì)算機(jī)專業(yè)知識(shí)。本文在研究虛擬儀表建模方法的基礎(chǔ)上,結(jié)合計(jì)算機(jī)技術(shù),闡述了可視化虛擬儀表設(shè)計(jì)平臺(tái)系統(tǒng)的研發(fā)過(guò)程。文中首先對(duì)可視化技術(shù)及使用VC++繪圖時(shí)消除屏幕閃爍的技術(shù)作了具體介紹;然后從面向?qū)ο蠼：蚒ML建模方面介紹并比較了幾種交互式建模方法;接著在對(duì)虛擬儀表構(gòu)成及設(shè)計(jì)特點(diǎn)研究的基礎(chǔ)上,提出基于“單元要素”的儀表單元定義方法,以及虛擬儀表的組合與裝配的模塊化設(shè)計(jì)方法,并在對(duì)其建模的基礎(chǔ)上將其進(jìn)行了可視化模型轉(zhuǎn)換;最后從系統(tǒng)實(shí)現(xiàn)角度出發(fā),詳細(xì)闡述了可視化虛擬儀表設(shè)計(jì)平臺(tái)系統(tǒng)的體系結(jié)構(gòu)設(shè)計(jì)與實(shí)現(xiàn)過(guò)程,并結(jié)合飛機(jī)虛擬維修的實(shí)例驗(yàn)證可視化虛擬儀表平臺(tái)系統(tǒng)的實(shí)用性與準(zhǔn)確性。
[Abstract]:With the human society entering the era of knowledge economy and the rapid development of information technology, instrumentation has been increasingly widely used in various fields, which has also made the instrument industry rapid development. Due to the limitation of manufacturing process, the sensitivity, accuracy, reproducibility and stability of traditional instruments will be affected to a certain extent. At the same time, the external environment will also affect the reliability of the instruments. In order to solve the above problems, And to meet the higher requirements of modern science and technology for measurement and control accuracy, on the basis of the rapid development of information technology, such as computer technology, virtual reality technology and network communication technology, virtual instrument emerged as the times require. And has received more and more attention and application. In order to make many types of virtual instruments can be developed easily and quickly, and to enable non-computer professionals to complete the design of virtual instruments, This paper has completed the design and development of the visual virtual instrument design platform system. The characteristic of the system is that it can define and design the corresponding virtual instrument according to the actual demand of the test task, at the same time, The system can meet the needs of ordinary users and does not require users to have too much computer expertise. This paper expounds the research and development process of visual virtual instrument design platform system. Firstly, the visualization technology and the technology of eliminating screen flicker when drawing with VC are introduced in detail. Then several interactive modeling methods are introduced and compared from the aspects of object-oriented modeling and UML modeling, and then, based on the research of the structure and design characteristics of virtual instrument, the definition method of instrument unit based on "element element" is proposed. The modular design method of combination and assembly of virtual instruments is presented, and the visual model transformation is carried out on the basis of modeling. Finally, from the point of view of system realization, The architecture design and implementation process of the visual virtual instrument design platform system are described in detail. The practicability and accuracy of the visual virtual instrument platform system are verified by the example of aircraft virtual maintenance.
