Abstract

The invention provides an SCM ( single chip microcomputer) based ultrasonic rainfall measurement device which comprises an SCM, a water inlet tube and a measuring tube, wherein the water inlet tube comprises a water inlet, a filter screen and a water inlet valve; the measuring tube adopts a double-tube structure, and the bottom of the double-tube structure is provided with a communication opening; the left tube of the measuring tube is connected with the water inlet tube, an ultrasonic probe and a temperature sensor are hermetically arranged above the right tube of the measuring tube, and a vent hole is arranged above the wall of the right tube of the measuring tube; and the ultrasonic probe and the temperature sensor are connected with the SCM. The SCM based ultrasonic rainfall measurement device provided by the invention is high in measurement accuracy and low in implementation cost; and by using the SCM based ultrasonic rainfall measurement device, the automatic and accurate rainfall measurement under the condition of any raininess can be implemented.

Description

technical field [0001] The invention relates to an ultrasonic rainfall measurement device based on a single-chip microcomputer, which belongs to the technical field of meteorological element measurement, in particular to the field of measurement of rainfall and rain intensity. Background technique [0002] The rain gauges used by meteorological departments are generally siphon rain gauges or tipping bucket rain gauges. The siphon rain gauge is composed of four parts: rain bearing, siphon, self-recording and shell. There is a floater chamber under the rain bearing device, and a floater is adorned in the room to link with the self-recording nib above. When the rainwater flows into the barrel, the float rises accordingly, and at the same time, it drives the self-recording pen on the float rod to lift up, and draws a precipitation rising curve that changes with time on the self-recording paper that rotates the bell barrel. When the water level in the float chamber reaches the ...
