摘　　要：针对目前常用虹吸式雨量计在虹吸时容易产生计量误差、难以实现自动化控制等问题,设计了一种基于双桶双虹吸称重雨量计和ARM处理终端的自动测报系统。该系统通过双桶双虹吸结构及称重传感器,有效地消除了降雨随虹吸流失造成的雨量计量误差,并实现了数据的自动采集。系统具有准确、及时、高效、无人值守等特点,经测试证明,系统运行稳定、精确度高、效果良好。At present,with commonly used siphon pluviometers the automation for rainfall measurement is hard to implement,and metering error often occurs,thus an automatic measuring system based on double-barrel and double-siphon weighting pluviometer and ARM processing terminal has been designed.This pluviometer system eliminates the metering error caused by drained rainfall in siphoning and implements automatic data acquisition function.It features precision,promptness,high effectiveness and unmanned operation.The test proves that the system is stable,highly precise and offers good results.
