Abstract

The invention discloses a rainfall detection device, a rain gauge and a rainfall determination method. The rainfall detection device comprises a capacitive rain sensing module which is used for detecting the rainfall condition and converting the detected rainfall change into a capacitance value; a piezoelectric rainfall sensing module which is used for detecting impact potential energy generated by raindrops and converting the impact potential energy into an analog signal; and a controller which is respectively connected with the capacitive rain sensing module and the piezoelectric rainfall sensing module, and is used for detecting rainfall according to the capacitance value transmitted by the capacitive rain sensing module and the impact potential energy transmitted by the piezoelectric rainfall sensing module. Through fusion of the two rainfall measurement modules, advantage complementation is realized, the rainfall detection accuracy and reliability are improved, and rainfall full-coverage detection is realized.

Description

technical field [0001] The invention relates to the technical field of rainfall measurement, in particular to a rainfall detection device, a rain gauge and a method for determining rainfall. Background technique [0002] Rainfall is a very important element in meteorological observation, which is closely related to human life. Excessive rainfall can easily induce floods, landslides and other natural disasters. At present, the tipping bucket rain gauge is the most widely used rainfall measuring instrument, and the tipping bucket rain gauge has the advantage of high precision. However, because it uses mechanical moving parts, it is easy to age. At the same time, its water inlet is easily blocked by debris, which affects the normal operation of the sensor. Every year, the meteorological department needs to spend a lot of manpower and material resources to maintain the tipping bucket rain gauge in the automatic station. , the normal measurement of rainfall can only be realized ...
