新一代天气雷达开关及触发器组件快速检修系统设计

Design of Fast Maintenance System for Next Generation Weather Radar Switch and Trigger Components

针对新一代天气雷达发射机开关和触发器组件故障频发,维修时效长,难度大等特点,提出了一种能够快速、便捷、高效、安全的新一代天气雷达开关和触发器组件关键芯片自动快速检测系统设计方案;该自动检测系统采用了机外脱机测试方法从而保证了雷达设备和人身的安全;该自动检测系统采用了发光二极管指示灯输出测试结果的自动快速测试方式,保证了雷达修复的较短时效;该自动检测系统直接测试雷达开关和触发器组件内部电路板常用关键芯片,而不是更换整个笨重的分机组件备件,从而使得维修新一代天气雷达故障变得便捷高效;新一代天气雷达开关和触发器快速检修系统研制完成后在多个台站得到了试用,试用实例结果表明其效果良好,可以给全国其他新一代天气雷达站快速维修新一代天气雷达提供借鉴和参考。

Because the switch and trigger assembly have fault frequently,maintenance effectiveness is long,and maintenance is difficult for the next generation weather radar transmitter,puts forward a kind of the next generation weather radar switch and trigger assembly key chips fast,convenient,efficient,safe and fast automatic detection system.The automatic testing system uses an off-line testing method to ensure the safety of the radar equipment and the human body.The automatic detection system adopts the automatic fast test method of the output test result of the light emitting diode indicator,which ensures the short time of the radar repair.The automatic detection system directly tests the key chips of the internal circuit boards of the radar switches and triggers,instead of replacing the cumbersome spare parts of the bulky components,so that the maintenance of the next generation weather radar is more convenient and efficient.The next generation of weather radar switch and trigger rapid maintenance system has been tested at several weather radar stations.The results show that the effect is good,and it can provide reference for other next generation weather radar stations to quickly repair the next generation weather radar.
