机载机电管理系统数据下载与分析设备设计

A Design for Downloading & Analyzing Data of Airborne Electro-mechanical System

针对机载机电管理系统具备独立的故障记录系统的特点,设计了一种基于NVRAM记录信息的数据下载与分析设备设计方案。在该设计中,基于一台数据下载与分析设备,可以实现多套机载机电管理系统故障记录数据的同时下载与解析,通过分析下载的机电管理系统数据,可以为分析机载机电管理系统工作状态和故障排除提供依据。试验结果和测试数据表明,该方案可有效节省硬件资源,缩短故障排查与定位时间,在SRU级维修中使用该设备,可以平均节省30%的排故时间,故障定位准确率提高3.5%。

This paper designs a test equipment for downloading and analyzing error recording data based on NVRAM for airborne electro-mechanical systems. In this design, based on a data download and analysis equipment, you can achieve multiple sets of airborne electromechanical m anagem ent system fault recording data is downloaded and parsed by Analysis electromechanical management system data can be uploaded electrom echanical management system work for analyzer provide the basis for status and troubleshooting. Test results and test data show that the scheme can effectively save hardware resources, reduce troubleshooting time and location,using the device in the SRU-level maintenance, you can save an average of 30% of the time troubleshooting, fault location accuracy rate of 3.5%.
