摘要
基于广州雷达一次天线动态错误的故障,将伺服系统分为机械、功放、通信链路和信号控制四个部分逐一分析排查,最后利用雷达数据处理软件BDAVC5分析故障时次的天线运行轨迹,发现问题出现在对天线俯仰的控制上,更换了数字控制单元的模拟板使故障得以排除。通过对故障排除过程的详细阐述,总结了天线动态错误报警故障源可能出现的机械、功效、通信链路和天线控制方面的问题及其初步判定方法。故障定位过程中的分析思路和方法为新一代天气雷达技术保障提供了借鉴。
In order to exclude a dynamic antenna fault of Guangzhou Doppler radar,the servo system is divided into four parts：machinery,amplifiers,communication link,and signal control to conduct failure analysis one by one.By using BDAVC5 to analyze the antenna running trajectory,it is found that the problem appeared on the control of antenna elevation,and the failure was excluded by replacing the analog board of the digital control unit.Through elaborating the process of failure analysis,the occasions that antenna dynamic faults may occur and preliminary identification methods are discussed.The ideas and methods that were used during the fault location process can provide a reference for the technical support of new generation weather radar.
