【摘要】：在航空電子系統(tǒng)(簡稱“航電系統(tǒng)”)研發(fā)過程中,經(jīng)常會(huì)出現(xiàn)某些航電設(shè)備的開發(fā)缺少其他航電設(shè)備或系統(tǒng)的協(xié)同支持,此時(shí),有必要開發(fā)航電仿真系統(tǒng)來模擬真實(shí)航電設(shè)備或系統(tǒng)運(yùn)行環(huán)境。傳統(tǒng)航電仿真系統(tǒng)的研發(fā)一般是根據(jù)特定仿真需求開發(fā)專用的仿真軟件,這使得當(dāng)被仿真設(shè)備或系統(tǒng)的需求發(fā)生變化時(shí)需要對(duì)仿真軟件進(jìn)行大量修改,甚至重新進(jìn)行系統(tǒng)軟件設(shè)計(jì),從而使得仿真軟件的可重用性和可維護(hù)性較差,降低了系統(tǒng)開發(fā)效率。因此,對(duì)航電仿真相關(guān)技術(shù)進(jìn)行研究,開發(fā)一個(gè)具有一定通用性、便于維護(hù)的航電仿真平臺(tái)具有重要的現(xiàn)實(shí)意義。無線電接口組件(Radio Interface Unit,簡稱RIU)是國產(chǎn)新一代飛機(jī)通信導(dǎo)航系統(tǒng)的數(shù)據(jù)控制中心,本文以RIU作為仿真載體,對(duì)航電仿真技術(shù)進(jìn)行了深入研究,采用層次化、模塊化以及面向?qū)ο笏枷朐O(shè)計(jì)了具有一定可擴(kuò)展性和可配置性的RIU半實(shí)物仿真系統(tǒng),該系統(tǒng)一定程度上可以作為一個(gè)通用性的航電仿真系統(tǒng)開發(fā)平臺(tái)。本文首先建立了RIU接口屬性模型和功能模型,以此為基礎(chǔ)對(duì)RIU半實(shí)物仿真系統(tǒng)進(jìn)行了總體方案設(shè)計(jì),通過將系統(tǒng)劃分為功能仿真系統(tǒng)和綜合監(jiān)控系統(tǒng),使得功能仿真和總線監(jiān)控能夠同步進(jìn)行,提高了仿真系統(tǒng)運(yùn)行效率。之后,對(duì)兩個(gè)子系統(tǒng)進(jìn)行了軟件層次劃分和模塊劃分,其中功能仿真系統(tǒng)被劃分為運(yùn)輸層、緩沖層和功能應(yīng)用層,由于緩沖層屏蔽了底層物理數(shù)據(jù)收發(fā)的細(xì)節(jié)并能向功能應(yīng)用層提供統(tǒng)一的數(shù)據(jù)存取接口,因此在開發(fā)同類航電仿真系統(tǒng)時(shí)只需根據(jù)仿真需求對(duì)功能應(yīng)用層進(jìn)行實(shí)現(xiàn)即可,從而可極大減少航電仿真系統(tǒng)開發(fā)過程中一些重復(fù)性工作,提高了仿真系統(tǒng)的通用性。接著本文運(yùn)用面向?qū)ο笏枷?在Visual Studio 2008開發(fā)環(huán)境中,使用MFC庫,采用C++語言對(duì)兩個(gè)子系統(tǒng)進(jìn)行了詳細(xì)設(shè)計(jì)與實(shí)現(xiàn)。文章最后在基于QAR數(shù)據(jù)的飛行環(huán)境模擬器中對(duì)RIU半實(shí)物仿真系統(tǒng)進(jìn)行了測試,驗(yàn)證了其預(yù)期功能。
[Abstract]:In the research and development of avionics system ("avionics system"), the development of some avionics equipment often lacks the collaborative support of other avionics equipment or systems. It is necessary to develop avionics simulation system to simulate real avionics equipment or system operation environment. The research and development of traditional avionics simulation system is to develop special simulation software according to specific simulation requirements, which makes it necessary to modify the simulation software when the requirements of the simulation equipment or system change. Even redesigning the system software makes the reusability and maintainability of the simulation software worse and reduces the system development efficiency. Therefore, it is of great practical significance to study the related technology of avionics simulation and to develop a avionics simulation platform which is universal and easy to maintain. Radio interface component (Radio Interface Unit, (RIU) is the data control center of the new generation aircraft communication and navigation system in China. In this paper, the avionics simulation technology is deeply studied with RIU as the simulation carrier, and the hierarchy is adopted. Modularization and object oriented idea are used to design the RIU hardware-in-the-loop simulation system which is extensible and configurable. The system can be used as a general avionics simulation system development platform to some extent. In this paper, the attribute model and function model of RIU interface are established firstly, based on which the overall scheme of RIU hardware-in-the-loop simulation system is designed, and the system is divided into functional simulation system and integrated monitoring system. The function simulation and bus monitoring can be carried out synchronously, and the efficiency of simulation system is improved. After that, the two subsystems are divided into software hierarchy and module, in which the functional simulation system is divided into transport layer, buffer layer and functional application layer. Because the buffer layer shields the details of physical data receiving and sending and can provide a unified data access interface to the functional application layer, it is only necessary to implement the functional application layer according to the simulation requirements when developing the similar avionics simulation system. Therefore, the repeatability of avionics simulation system can be greatly reduced and the generality of the simulation system can be improved. Then, using the object oriented thought, in the Visual Studio 2008 development environment, using the MFC library, using C language to carry on the detailed design and the realization to the two subsystems. Finally, the RIU hardware-in-the-loop simulation system is tested in the flight environment simulator based on QAR data, and its expected function is verified.
