Nowadays , because of the advantage in the real - time simulation and the authenticity of the result , semi - physical simulation has been applied to many fields widely . the simulation for the avionic system and devices is an important branch of the semi - physical simulation 目前,由于在仿真的實(shí)時(shí)性以及真實(shí)性等方面具有的強(qiáng)大優(yōu)勢(shì),半實(shí)物仿真技術(shù)在眾多領(lǐng)域都得到了廣泛的應(yīng)用,航空電子系統(tǒng)(簡(jiǎn)稱航電系統(tǒng))及其子系統(tǒng)的半實(shí)物仿真應(yīng)用就是其中的一個(gè)重要分支。
This paper studies the design documents of the avionic system detailedly , including the interface control document and detailed design requirements , and summarizes the data structures and the communication formats of the system , and designs the simulation database . this paper also studies some protocols such as gjb289a , arinc429 and udp etc , and then determines the methods of data processing . according to the theory of the software engneering , this paper completes the requirements analysis , the globle 本文根據(jù)設(shè)備的具體設(shè)計(jì)要求,完成了仿真設(shè)備的硬件設(shè)計(jì);詳細(xì)研究了航電系統(tǒng)的系統(tǒng)設(shè)計(jì)文件? ?接口控制文件和詳細(xì)設(shè)計(jì)要求,總結(jié)出了航電系統(tǒng)的數(shù)據(jù)結(jié)構(gòu)和消息通訊格式,并在此基礎(chǔ)上設(shè)計(jì)了用來(lái)表達(dá)仿真對(duì)象的關(guān)系型仿真數(shù)據(jù)庫(kù);研究了gjb289a 、 arinc429等總線協(xié)議以及udp網(wǎng)絡(luò)協(xié)議,明確了各類數(shù)據(jù)的處理方法;按照軟件工程的開發(fā)理論,完成了仿真軟件的需求分析、概要設(shè)計(jì)和詳細(xì)設(shè)計(jì),進(jìn)而通過(guò)編程在labwindows / cvi環(huán)境下實(shí)現(xiàn)了一個(gè)界面友好、靈活通用的仿真平臺(tái)。
Most of the current semi - physical simulators of the avionic system consist of special software and hardware , which results in the necessity to develop simulators independently for different avionic devices . simultaneously , according to the requirement of the software engineering , software must need to be strictly tested after developed or modified . this will consume much energy and time , and makes the software hard to be maintained 當(dāng)前的航電系統(tǒng)半實(shí)物仿真器多是使用專用的硬件設(shè)備搭配專用的仿真軟件來(lái)實(shí)現(xiàn)的,這種專用性就造成了需要針對(duì)不同航電設(shè)備單獨(dú)開發(fā)仿真器的問(wèn)題,同時(shí)按照軟件工程的要求,軟件的開發(fā)以及修改都要經(jīng)過(guò)嚴(yán)格的測(cè)試,這就使得仿真系統(tǒng)的開發(fā)耗費(fèi)大量的精力和時(shí)間,同時(shí)使得仿真軟件難以維護(hù)。
