飞行器自动故障诊断工具

Auto fault diagnosis tool for aircraft

目前大部分C-5飞行器存在大量的维修问题,据统计,每22个C-5飞行器就有8个不能正常执行任务,因此改进C-5飞行器的故障诊断系统非常必要。文中介绍改进后的MADARS Ⅲ战场维修故障诊断系统将极大地增强故障定位精度。 MADARS在飞行器工作期间使用计算机记录上百个测试点的数据,测试点自动将故障代码对识别的故障元件自动进行触发,许多元件故障需要进一步隔离以便维修,MADARS通过通用处理接口系统(GPIS)下载数据,并进行有效数据的分析。GPIS还将数据传输到数据库服务器 (QLD),测试点数据可以通过QLD存取,绘制曲线,与相关测试点比较,并出具报告,供维修人员使用。

At present, there are many maintenance problems about aircraft C-5. According to statistics, 8 C-5 in 22 will not perform the mission correctly. Therefore, it is necessary to improve the fault diagnosis system. MADARS Ⅲ, which is an improved fault diagnosis system for battlefield maintenance, will significantly enhance the precision of fault location. During the flight process, computer is used to record data from hundreds of test points. Fault codes are automatically used to trigger fault component, faults of many components should be isolated for diagnosis. MADARS uses general-purpose interface system to download data, and perform data analysis. GPIS will also transfer data to QLD, which is a development tool of maintenance report based on aero bus. Data from test points can be stored and plotted through QLD.
