摘要
针对在野外环境中如何实时、准确地获取降雨资料的问题,在综合考虑各类雨量计的原理、使用方法以及优缺点后,设计了一种基于应变式压力传感器的新型虹吸式雨量计.它具有传统虹吸式雨量计低功耗、测量不受降雨强度大小的限制的优势,并通过压力传感器保证了测量精度,而且对虹吸过程中的降雨采用最小二乘法的算法进行补偿.最后,经过算法优化后的数据通过数据采集器上的GSM模块实现数据的远距离传输,从而大大提高了它的应用范围.
In order to get the accurate rainfall data timely in an unattended wilderness environment,a novel siphon rain gauge design based was presented on a strain-type pressure sensor after an integrated consideration of the principles,operation methods,merits and faults of various types of rain gauges.This rain gauge not only keeps the advantages of the traditional siphon rain gauge such as low power and not subject to the restrictions of rainfall s intensity,but also ensures the measurement accuracy by a pressure...
