自动气象站雷击故障分析处理

Analysis on Lightning Breakdown of Automatic Weather Station

针对CAWS600自动气象站遭雷击出现的故障进行分析,结果表明:自动站电源故障、串口隔离器故障和地温传感器故障是自动气象站雷击事故中最常见的几种故障,总结和归纳这些快速处理方法,可以避免或减少雷击事故。针对自动站雷击事件造成的数据缺测,提出对相关数据进行人工干预数据处理的方法,以保持观测数据序列的完整性。

According to the automatic weather station CAWS600 lightning fault analysis, it showed that automatic station power failure, serial port isolator fault and ground temperature sensor failure are the most common trouble of lightning accident for automatic weather station. The thesis summari- zes and concludes the fast processing method to avoid or reduce the hghtning accident. For automatic weather station failure caused the missing data and abnormality, the corresponding treatments are put forward to maintain the integrity and accuracy of the observation data sequence.
