【摘要】：機(jī)載VHF導(dǎo)航設(shè)備是飛機(jī)無線電導(dǎo)航的不可缺少的一部分,它不僅提供了如飛機(jī)的VOR方位角等重要的導(dǎo)航信息,還可以在氣象條件惡劣和能見度差的條件下給駕駛員提供引導(dǎo)信息,保證飛機(jī)安全進(jìn)近和著陸。介于機(jī)載VHF導(dǎo)航設(shè)備的重要作用,對于其的研究和開發(fā)也隨著航空電子的發(fā)展日益增多,研究深度也在增強(qiáng)。目前對于機(jī)載VHF導(dǎo)航設(shè)備的科研主要從仿真和實(shí)物兩個方面進(jìn)行。仿真研究主要是對機(jī)載VHF導(dǎo)航設(shè)備進(jìn)行分析,建立設(shè)備的數(shù)學(xué)模型,然后用計算機(jī)軟件的形式再現(xiàn)設(shè)備的功能,這在模擬飛行中起到了重大的意義。實(shí)物研究則是建立VHF導(dǎo)航設(shè)備的地面臺,在實(shí)際飛行中記錄實(shí)時的機(jī)載甚高頻導(dǎo)航信號。本文是對機(jī)載VHF導(dǎo)航設(shè)備的設(shè)計與實(shí)現(xiàn)采用半實(shí)物仿真研究,將一些在實(shí)驗(yàn)室中無法獲得的信號用仿真的形式代替,一方面對機(jī)載VHF導(dǎo)航系統(tǒng)進(jìn)行分析、建模和仿真;另一方面則是構(gòu)建機(jī)載VHF導(dǎo)航設(shè)備的輸出信號,使其與真實(shí)的設(shè)備盡可能的接近,成為滿足航空工業(yè)標(biāo)準(zhǔn)的物理信號。在現(xiàn)代飛機(jī)上,VOR導(dǎo)航系統(tǒng)的機(jī)載設(shè)備與儀表著陸系統(tǒng)的航向信標(biāo)的機(jī)載設(shè)備的有些部分是公用的,因此本文主要以VOR導(dǎo)航為研究對象。本文采用PC機(jī)加上多個下位機(jī)設(shè)備的形式來完成機(jī)載VHF導(dǎo)航設(shè)備的半實(shí)物仿真系統(tǒng)。PC機(jī)有著兩部分功能,首先需要對VHF導(dǎo)航系統(tǒng)的數(shù)學(xué)模型進(jìn)行Matlab仿真,讓用戶可以清楚的知道其中的原理,再次需要模擬VOR地面臺,對下位機(jī)設(shè)備起到控制和監(jiān)控的目的。下位機(jī)設(shè)備主要實(shí)現(xiàn)機(jī)載VHF導(dǎo)航設(shè)備的輸出信號功能,如VOR方位角、航道偏離、向/背臺等信號。通過PC機(jī)建立地面臺數(shù)據(jù)庫和控制界面對下位機(jī)系統(tǒng)各模塊的統(tǒng)一管理,使系統(tǒng)協(xié)調(diào)、有序的工作。這種半實(shí)物仿真研究既可以作為航空電子系統(tǒng)仿真研究的重要組成部分,同時又可以為模擬飛行和通用測試的其它航電設(shè)備提供實(shí)時的VHF導(dǎo)航信號。
[Abstract]:Airborne VHF navigation equipment is an indispensable part of aircraft radio navigation. It not only provides important navigation information such as the VOR azimuth of aircraft. It can also provide guidance information to the pilot under the bad weather conditions and poor visibility to ensure the safe approach and landing of the aircraft. In view of the important role of airborne VHF navigation equipment, its research and development are increasing with the development of avionics, and the research depth is also increasing. At present, the research of airborne VHF navigation equipment is mainly carried out from two aspects: simulation and object. The simulation research is mainly to analyze the airborne VHF navigation equipment, to establish the mathematical model of the equipment, and then to reproduce the function of the equipment in the form of computer software, which plays an important role in the simulation flight. The real object research is to establish the ground station of VHF navigation equipment and record the real time airborne VHF navigation signal in the actual flight. In this paper, the design and implementation of airborne VHF navigation equipment is studied by hardware-in-the-loop simulation. Some signals that can not be obtained in the laboratory are replaced by simulation. On the one hand, the airborne VHF navigation system is analyzed, modeled and simulated. On the other hand, the output signal of airborne VHF navigation equipment is constructed so that it is as close as possible to the real equipment and becomes a physical signal that meets the aviation industry standard. Some parts of the airborne equipment of VOR navigation system and the onboard equipment of heading beacon of instrument landing system are common, so this paper mainly focuses on VOR navigation. In this paper, the hardware-in-the-loop simulation system of airborne VHF navigation equipment is completed in the form of PC and multiple lower computer devices. PC has two functions. Firstly, the mathematical model of VHF navigation system needs to be simulated by Matlab. So that the user can clearly understand the principle, again need to simulate the VOR ground station, to the lower computer equipment control and monitoring purposes. The lower computer equipment mainly realizes the output signal function of the airborne VHF navigation equipment, such as the VOR azimuth, the channel deviation, the direction / the back station and so on. The database of the ground station and the control interface are set up by PC to manage all the modules of the lower computer system, so that the system can work in a coordinated and orderly manner. This hardware-in-the-loop simulation study can not only be an important part of avionics system simulation research, but also provide real-time VHF navigation signal for other avionics equipment which simulates flight and general test.
