【摘要】 通过分析目前我国新一代天气雷达的维修保障现状,提出利用雷达故障诊断系统来辅助和代替传统的雷达故障诊断手段,以达到缩短故障维修时间、规范维修维护方法和提高维修效率的目的。论文以CINRAD/SA型号的天气雷达为对象,通过对CINRAD/SA天气雷达系统结构的深入研究,结合雷达现有的故障定位功能,确定了故障信息的采集方式;收集和分析了2002—2014年期间近70部CINRAD/SA雷达相对完整的故障维修案例,基于故障树分析法(FTA)建立了雷达故障树,并以发射机子系统为例,进行了故障树的定性分析和定量分析,得到初始数据。在分析和研究的基础上,开发了"CINRAD/SA天气雷达故障诊断系统",为雷达故障诊断提供指导思路。更多还原

【Abstract】 The current maintenance support situation of the new-generation weather radar in China at present is introduced.The radar fault diagnose system is used to assist and replace the traditional radar fault diagnose means,which can shorten the time for maintaining radar faults,standardize the radar maintenance means,and improve the efficiency of radar maintaining.Taking the CINRAD/SA weather radar as an example,through a detailed study of the CINRAD/SA weather radar system,in combination with the radar fault location function,the collection method of radar fault messages is determined.About70 relatively complete cases of CINRAD/SA radar fault maintenance from 2002 to 2014 are collected and analyzed.Based on the Fault Tree Analysis(FTA),the radar fault tree is developed.The radar transmitter is taken as an example to make the qualitative and quantitative analysis of the fault tree,and the initial data are obtained.Based on the analysis,the CINRAD/SA Weather Radar Fault Diagnosis System is developed,which provides guidance for radar fault diagnosis.更多还原
