摘要
在详细介绍CINRAD/SB雷达数字伺服系统加电控制、天线状态信号流程的基础上,分析出数字伺服系统无法上电3方面原因:负载过载导致空气开关保护性断电;伺服系统加电信号不正常;制动器过流导致温度超限。总结了CINRAD/SB雷达伺服系统无法上电故障的分析方法和诊断流程。通过诊断流程详细论述两例伺服无法上电的复杂故障分析和排除过程,以及在台站无配件更换情况下,充分利用雷达线路特点暂时采用应急方法尽快恢复雷达运转的方法,保证灾害性天气监测的需求。为新一代天气雷达技术支持和保障提供借鉴。
A detailed instruction about the CINRAD/SB digital Servo Control power structures and the antenna-state signal process is made,and three reasons are discussed for the CINRAD/SB servo power-off failure： the protective power-off of the air switch resulted from overloading,abnormal power-off signals of the server systems,and abnormal temperature induced by the overflow of the brake.The analysis methods and diagnosis process of that the CINRAD/SB servo system power-off failure are summed up,and the detailed explanation is given about how to find out and get rid of the faults in two complex cases of the CINRAD/SB servo system power-off failure and the methods for restoring radar operation in emergency case without spare parts available by making full use of the existing facilities according to the features of the radar lines.
