【摘要】：本论文依托于与某飞机维修公司合作的项目WXA-2100机载气象雷达系统自动测试项目和WMA-701X机载气象雷达天线支架自动测试项目。机载气象雷达系统是民航飞机上的重要组成部分,其测试过程复杂繁琐,而且传统的手工测试效率低下,目前大部分民航企业采用自动测试平台进行航电设备的检测。我国目前的航空自动测试平台主要进口国外设备厂商,国外的自动检测系统不仅价格昂贵,而且对其它厂商的设备兼容性不足。本论文针对WXA-2100气象雷达及WMA-701X雷达天线支架设计了一套通用化自动测试系统,可完成该系列型号气象雷达及雷达天线支架的自动测试工作,达到提高效率降低成本的目的。本论文首先介绍了自动化测试在民用航空领域的发展现状,然后分析了整套自动测试系统的软件和硬件需求,提出了整个系统的设计框架。自动测试系统设计包含了硬件设计,软件设计,以及针对待测组件气象雷达和天线支架的具体测试。硬件平台以GPIB总线为基础,连接多种测试仪器。软件平台以QT作为开发框架,选择Lua这门脚本语言作为自动测试脚本,实现了权限管理,驱动封装,脚本编辑、运行和调试等功能。最后根据测试手册在自行设计的自动测试系统中实现了气象雷达收发机和雷达天线支架的自动化测试,论文中详细介绍了测试中遇到的重点问题和难点问题及其对应的解决方案,包括ARINC 453气象数据格式的解析并生成气象图像,雷达天线支架串行通讯格式的分析过程等。本论文最终完成了一套通用化自动测试系统,该系统支持气象雷达以及雷达天线支架的自动测试,系统可以重构,容易扩展,不同用户根据各自的测试需求,在硬件平台上完成测试资源配置、接口适配器设计、在软件平台上完成测试程序开发。这样测试系统的研制人员不必掌握过多的专业测试技能就可以方便、快速地对设备进行测试。
[Abstract]:This paper is based on WXA-2100 airborne weather radar system automatic test project and WMA-701X airborne weather radar antenna support automatic test project. Airborne weather radar system is an important part of civil aviation aircraft, its testing process is complex and cumbersome, and the traditional manual testing efficiency is low. At present, most civil aviation enterprises use automatic test platform to detect avionics equipment. At present, China's aviation automatic test platform mainly imports foreign equipment manufacturers. The foreign automatic testing system is not only expensive, but also not compatible with other manufacturers. In this paper, a universal automatic test system is designed for WXA-2100 meteorological radar and WMA-701X radar antenna support. The automatic test work of the series of meteorological radar and radar antenna support can be completed, and the purpose of improving efficiency and reducing cost is achieved. This paper first introduces the development of automated testing in the field of civil aviation, then analyzes the software and hardware requirements of the whole automated test system, and puts forward the design framework of the whole system. The design of automatic test system includes hardware design, software design, and test for meteorological radar and antenna support. The hardware platform is based on GPIb bus and connects many kinds of test instruments. The software platform takes QT as the development framework and chooses Lua as the automatic test script. It realizes the functions of privilege management, drive encapsulation, script editing, running and debugging. Finally, according to the test manual, the automatic test of meteorological radar transceiver and radar antenna support is realized in the self-designed automatic test system. In this paper, the key and difficult problems encountered in the test and their corresponding solutions are introduced in detail, including the analysis of ARINC453 meteorological data format and the generation of meteorological images, the analysis process of radar antenna support serial communication format and so on. In this paper, a universal automatic test system is completed. The system supports the automatic testing of weather radar and radar antenna support. The system can be reconfigurable and easy to expand. Test resource configuration, interface adapter design and test program development are completed on hardware platform. In this way, the developer of the test system can test the equipment conveniently and quickly without having to master too many professional test skills.
