| 摘要: |
| CINRAD/CD天气雷达在体扫过程中出现系统状态报警，雷达系统掉高压，且实时处理监控和采集软件、实时控制显示终端软件的遥控开关机功能均失效。在深入理解雷达监控系统工作原理的基础上，对雷达监控系统的工作过程进行了分析与梳理，再对相关重要器件进行检测和替换排查，最后确定了此次故障的源头器件，即配电监控组件的部分器件出现功能性损坏，导致连接整机监控通讯接口的RS485接口芯片功能异常。 |

| Abstract: |
| The CINRAD/CD weather radar has a system status alarm during the body scanning process, the radar system drops high voltage, and the remote control switch function of the real-time processing monitoring and acquisition software and the real-time control display terminal software is invalid. On the basis of in-depth understanding of the working principle of the radar monitoring system, the working process of the radar monitoring system was analyzed and sorted out, and then the relevant important components were detected and replaced. Finally, the source of the failure was determined, that is, some components of the power distribution monitoring module were functionally damaged, resulting in abnormal functions of the RS485 interface chip connected to the monitoring communication interface of the whole machine. |
