CINRAD/CC雷达伺服分系统故障的排除

Breakdown elimination of CINRAD/CC radar servo subsystem

CINRAD/CC雷达伺服分系统是多普勒天气雷达的重要组成部分,伺服分系统直接接收来自监控分系统的控制指令,由其计算处理后,输出电机驱动信号,完成天线的方位和俯仰扫描控制;同时它将天线的实时方位角、仰角数据送往信号处理分系统,将故障信息送往监控分系统。本文根据伺服系统的功能与特点结合工作中遇到的故障对伺服系统进行了详细的剖析,为雷达的稳定运行提供保障,充分发挥多普勒天气雷达在防灾减灾中的重要作用。

The CINRAD/CC radar servo subsystem is the important component in the Doppler weather radar. The servo subsystem directly receive control command from the monitoring subsystem. After computation processing,it outputs the motor-driven signal and completes antenna position and pitches scanning control. Simultaneously, the data of real-time azimuth and the elevation angle are escorted to the signal processing subsystem, while the breakdown information is escorted to the monitoring subsystem. According to the functions and characteristics of serveo subsystem and the breakdown during operation,this paper detailed analyses the servo subsystem, which provides the safeguard for radar steady operation and fully displays the important role of Doppler weather radar in the disaster prevention.
