【摘要】：对于飞机来说,用来保护飞机的机载机电系统是不可缺少的一部分。由于现在机载机电系统逐步向智能化和全面化方向发展,研制机载机电系统的风险和难度也就变得越来越大。为了降低研制风险,提高研制质量,在研发过程中合理的应用仿真测试技术进行大量的仿真试验是一种必要的研发手段。本论文课题研究基于某飞机研究所机电分系统仿真试验项目。根据对机电分系统仿真激励器的需求分析,本文提出了应用虚拟仪器技术组建以NI PXI工控机为硬件核心的机电分系统仿真激励器,用来实施仿真试验的解决方案。机电分系统仿真激励器主要完成液压、燃油、环控液冷、起飞着陆、防除冰、防火各分系统的功能仿真,模拟各机电分系统(除供电、刹车分系统外)的接口状态、工作逻辑、告警信息并接收控制指令,以此来验证机电管理系统对机电各分系统的控制功能。本论文首先简述了机电子系统仿真激励器的研究背景和意义,分析了国内外应用虚拟仪器技术完成仿真测试试验的研究现状和发展趋势。接着进行虚拟仪器、Lab VIEW以及数据采集系统的概述。通过对机电分系统仿真试验的需求分析,确定总体设计方案。然后详细介绍其硬件配置和软件部分设计,其中软件部分主要包括用户界面模块的设计、板卡数据采集模块的设计、RS-422通讯信息模块的设计以及数据保存与回放模块的设计。最后介绍了整个机电子系统仿真器的调试测试过程,对实际试验过程中出现的问题进行分析并及时解决。经过项目论证、硬件搭建、软件开发、功能调试等阶段,该机电仿真激励器已经实际应用到某型飞机的机电管理系统仿真试验中,其功能和技术指标符合实际应用需求,达到了预期的研究成果。
[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.
