水文遥测翻斗式雨量计的误差分析

Error Analysis of Hydrometeorology Tipping-bucket Rainometer

自然降水量是水资源的重要组成部分,而观测降水量是水文遥测工作的重要内容之一,其观测精度的大小对洪涝灾害预测精度、水文水利规划精度有着非常大的影响。翻斗式雨量计是较为常用的观测雨量的工具,但其在应用过程中仍存在较大误差。本文首先分析翻斗式雨量计的结构和原理,然后重点探讨其在应用过程中存在的误差,并提出了相应的预防和诊断措施,以期为水文遥测工作人员在降水量观测的实践应用中提供参考。

Natural precipitation is an important part of water resources, and the observed precipitation is an important part of hydrological telemetry. The accuracy of its observation has a great impact on the accuracy of flood forecasting and the accuracy of hydrologic and water conservancy planning. Tipping bucket rainfall is more commonly used observation tools, but in the application process, there is a big error. This paper first analyzed the structure and principle of tipping bucket rain gauge, and then focused on the error existing in the application process, and put forward corresponding measures for prevention and diagnosis, in order to provide refreence for staff in the practical application of hydrological telemetry rainfall observation.
