摘要
SL3-1型双翻斗式自动雨量站因其结构简单、分辨率高等优点在气象、水文等行业得到广泛的业务应用,但也因其结构特性易产生多种数据失真的问题。文章分析了蜘蛛网粘连、异物阻碍以及传感器至数据采集器之间的接触不良导致的特殊隐性故障。给出了通过临近站资料对比、增加维护校准频次等措施,及时发现故障并加以排除。还可通过双套仪器进行互校,或人工观测仪器定期比对等方法,避免产生严重失真的记录。
SL3-1 tipping bucket automatic rainfall station is widely used in the industry of meteorological and hydrological etc because of its advantages of simple structure and high resolution etc.But its structural characteristics are also easy to cause several problems of data distortion.This paper analyzes the special hidden failures such as spider web adhesion,foreign body hindrance and bad contact between the sensor and the data collector.Through comparing data of the nearby station and increasing the frequency of maintenance and calibration,the failures can be found and solved on time.By means of mutual-emendation between two sets or regular comparison on artificial observation instruments,the record with serious distortion can be avoided.
