【摘要】：對于飛機來說,用來保護(hù)飛機的機載機電系統(tǒng)是不可缺少的一部分。由于現(xiàn)在機載機電系統(tǒng)逐步向智能化和全面化方向發(fā)展,研制機載機電系統(tǒng)的風(fēng)險和難度也就變得越來越大。為了降低研制風(fēng)險,提高研制質(zhì)量,在研發(fā)過程中合理的應(yīng)用仿真測試技術(shù)進(jìn)行大量的仿真試驗是一種必要的研發(fā)手段。本論文課題研究基于某飛機研究所機電分系統(tǒng)仿真試驗項目。根據(jù)對機電分系統(tǒng)仿真激勵器的需求分析,本文提出了應(yīng)用虛擬儀器技術(shù)組建以NI PXI工控機為硬件核心的機電分系統(tǒng)仿真激勵器,用來實施仿真試驗的解決方案。機電分系統(tǒng)仿真激勵器主要完成液壓、燃油、環(huán)控液冷、起飛著陸、防除冰、防火各分系統(tǒng)的功能仿真,模擬各機電分系統(tǒng)(除供電、剎車分系統(tǒng)外)的接口狀態(tài)、工作邏輯、告警信息并接收控制指令,以此來驗證機電管理系統(tǒng)對機電各分系統(tǒng)的控制功能。本論文首先簡述了機電子系統(tǒng)仿真激勵器的研究背景和意義,分析了國內(nèi)外應(yīng)用虛擬儀器技術(shù)完成仿真測試試驗的研究現(xiàn)狀和發(fā)展趨勢。接著進(jìn)行虛擬儀器、Lab VIEW以及數(shù)據(jù)采集系統(tǒng)的概述。通過對機電分系統(tǒng)仿真試驗的需求分析,確定總體設(shè)計方案。然后詳細(xì)介紹其硬件配置和軟件部分設(shè)計,其中軟件部分主要包括用戶界面模塊的設(shè)計、板卡數(shù)據(jù)采集模塊的設(shè)計、RS-422通訊信息模塊的設(shè)計以及數(shù)據(jù)保存與回放模塊的設(shè)計。最后介紹了整個機電子系統(tǒng)仿真器的調(diào)試測試過程,對實際試驗過程中出現(xiàn)的問題進(jìn)行分析并及時解決。經(jīng)過項目論證、硬件搭建、軟件開發(fā)、功能調(diào)試等階段,該機電仿真激勵器已經(jīng)實際應(yīng)用到某型飛機的機電管理系統(tǒng)仿真試驗中,其功能和技術(shù)指標(biāo)符合實際應(yīng)用需求,達(dá)到了預(yù)期的研究成果。
[Abstract]:For aircraft, the airborne electromechanical system used to protect aircraft is an indispensable part. In order to reduce the risk and improve the quality of the development, the risk and difficulty of developing the airborne electromechanical system becomes more and more serious. It is necessary to apply simulation test technology to a large number of simulation tests in the process of research and development. This thesis is based on a certain aircraft research institute electromechanical subsystem simulation test project. The requirement analysis of system simulation exciter, In this paper, a simulation exciter of electromechanical subsystem based on NI PXI industrial control computer is constructed by using virtual instrument technology, which is used to carry out simulation test. The emulation stimulator of electromechanical subsystem mainly completes hydraulic, fuel and environment controlled liquid cooling. Functional simulation of each subsystem for take-off and landing, anti-ice, anti-fire, simulating interface status, working logic, alarm information and receiving control instructions of each electromechanical subsystem (except for power supply and brake subsystem), In order to verify the control function of the electromechanical management system to each sub-system of electromechanical system, this paper firstly introduces the research background and significance of the simulation exciter of the mechanical and electronic system. This paper analyzes the research status and development trend of virtual instrument technology used in simulation test and test at home and abroad. Then, the paper summarizes the virtual instrument VIEW and data acquisition system, and analyzes the requirement of simulation test of electromechanical subsystem. Then the hardware configuration and the software design are introduced in detail, in which the software part mainly includes the design of the user interface module. The design of card data acquisition module and the design of RS-422 communication information module as well as the design of data saving and playback module. Finally, the debugging and testing process of the whole electromechanical subsystem simulator is introduced. Analyze and solve the problems in the process of actual test. After the stages of project demonstration, hardware construction, software development, function debugging and so on, The electromechanical simulation exciter has been applied to the simulation test of the electromechanical management system of a certain aircraft. Its function and technical specifications are in line with the practical application requirements and the expected research results have been achieved.
