【摘要】：航空电子系统在飞机中占有十分重要的地位,伴随我国航空航天事业的发展,综合模块化航空电子系统(IMA)的功能检测和故障排查越发显示出其重要性。自动检测系统的设计和研发也受到了国内外专家的高度重视,虚拟仪器技术的发展为我们提供了快捷、方便的技术手段,我们可以运用虚拟仪器技术灵活的组建各种自动测试系统以达到硬件资源和软件资源的共享及使用。论文以中航工业某研究所航空电子系统中航空控制板故障自动检测平台的研发为背景,设计出了一种航空控制板故障自动检测系统。经过对比和研究国内外检测平台的搭建方法,本文提出了一种基于PXI总线、PXI机箱、光纤通信设备、NI板卡、LabVIEW8.0专业开发板,及LM3S600的航空控制板故障检测系统通用平台,该平台能够实现设备的自动检测及故障定位,将以太网作为媒介传送故障信息至相关工作人员处,方便工作人员从远端完成设备故障状态确认、故障排查等工作。这对工程师完成故障排查及检修工作带来了极大的便利性,提高了人员工作效率,同时也为航空电子设备的运行提供了良好的保障。硬件设计,依据检测纲要和待测试项的具体指标设计出该测试平台。以NI板卡集成为硬件基础,平台设计包括基于LabVIEW的上位机监控程序的开发、PXI机箱及光纤通信套件的选用、测试结果远端传输设计、传递信息媒介选择等。用于新老设备间进行匹配的电路板,我们自主设计了以LM3S600航空控制板为核心构成的电子负载板以完成该功能。软件设计,在LabVIEW8.0专业开发版的软件环境下,进行系统软件的设计与调试。软件界面能够直观反映设备的硬件配置及功能控制,能够使得状态机和系统有机的结合在一起,从而用LabVIEW完成了软件主要框架的搭建工作。分层调用可以使测试子项程序模块得到动态控制,基于Access的故障定位查询,可快速准确的定位到故障点。同时系统可将检测到的数据进行分析,并将结果实时显示和储存。测试数据的远程传输,我们可通过Lab VIEW 的 Web Publish Tool 得以实现。该测试设备的成功研发与应用,为我国航空电子系统测试领域的发展起到了非常积极的作用。
[Abstract]:Avionics system occupies a very important position in aircraft. With the development of China's aviation and space industry, the function detection and troubleshooting of integrated modular avionics system (IMA) is becoming more and more important. The design and research and development of the automatic detection system have also been highly valued by the experts at home and abroad, and the development of virtual instrument technology. It provides us with quick and convenient technical means. We can use virtual instrument technology to build various automatic test systems to achieve the sharing and use of hardware resources and software resources. The paper is based on the research and development of the aircraft control board fault automatic detection platform in the avionics system of a Research Institute of China aeronautical industry. A kind of automatic fault detection system for air control board is developed. After comparing and studying the construction methods of detection platform at home and abroad, this paper presents a general platform based on PXI bus, PXI chassis, fiber communication equipment, NI card, LabVIEW8.0 professional development board, and LM3S600 for aviation control board barrier detection system. This platform can implement equipment. Automatic detection and fault location, the Ethernet as the medium to transmit fault information to the relevant staff, convenient staff from the far end to complete the equipment fault status confirmation, troubleshooting and other work. This has brought great convenience to the engineer to complete the troubleshooting and maintenance work, improved the efficiency of the personnel and also for the voyage. The operation of the air electronic equipment provides a good guarantee. The hardware design is designed according to the testing outline and the specific indexes of the test items. The hardware base is integrated with the NI card. The platform design includes the development of the monitor program based on the LabVIEW, the selection of the PXI chassis and the optical fiber communication suite, and the remote transmission of the test results. Design, transmission of information media selection, and so on. Used for matching circuit board between new and old equipment, we independently designed the electronic load board composed of LM3S600 air control board as the core to complete this function. Software design and software design and debugging under the software environment of LabVIEW8.0 professional development version. The software interface can be straight. The view reflects the hardware configuration and function control of the equipment, which can combine the state machine and the system organically, so as to complete the construction of the main framework of the software with LabVIEW. The hierarchical call can make the test sub program module get dynamic control, based on the Access fault location query, and can quickly and accurately locate the fault point. The system can analyze the detected data and display and store the results in real time. The remote transmission of the test data can be realized through the Web Publish Tool of Lab VIEW. The successful development and application of the test equipment have played a very active role in the development of China's avionics system testing field.
