摘　　要：翻斗式雨量计因雨强影响会产生很大的误差,虹吸雨量计不能数字化降雨过程,并需要人工测量虹吸水量进行虹吸订正。本研究成果利用翻斗计量降雨过程,用精确的虹吸计量值智能校正翻斗的误差,综合了翻斗计量和虹吸计量的优点,将分辨率为0.1mm的翻斗雨量计的测量误差从±15%减小到±2%,因此,JSP-1型虹吸校正翻斗雨量计具有很高的精度。Tipping bucket rainfall recorders affected by the rainfall intensity have great error.Siphon rainfall recorders can not be digitized rainfall process and need artificial revisions by measuring siphon water.In the study,dumpers were used to measure rainfall process,the precise siphon measurement was used for intelligently amending dumpers errors,so that the relative uncertainty of tipping bucket rainfall recorder with a resolution of 0.1 mm can be decreased by ±15% to ±2%.The JSP-1 tipping bucket rainfall recorder by siphon correction has high precision.
