新型虹吸式雨量测量仪的研制

Develop of New Siphon Rainfall Measuring Instrument

设计了一种基于应变式压力传感器的新型虹吸式雨量计。新型虹吸式雨量计在保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等优势的基础上,又通过压力传感器保证了测量精度,还能对虹吸时的降雨进行补偿,并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。

This paper presents a novel siphon rain gauge design based 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 sensor,besides,the rainfall on the siphon can be compensated.It can realize the long-distance data transmission through the GSM module on the data collector,thus greatly increases its scope of application.
