Electric control measuring cylinder type digital intelligent precipitation gauge

Abstract

The invention belongs to the technical field of a precipitation detecting device, and particularly relates to an electric control measuring cylinder type digital intelligent precipitation gauge. The invention provides the electronic precipitation gauge which has advantages of large bearable rain strength range and automatic fault alarm, namely the electric control measuring cylinder type digital intelligent precipitation gauge. The electric control measuring cylinder type digital intelligent precipitation gauge comprises a rain containing funnel and is structurally characterized in that the lower end of the rain containing funnel is provided with a buffering water containing tank; the lower end of the buffering water containing tank is connected with an upper inlet of a main measuring tubebody through a measuring cylinder upper electromagnetic valve; the lower outlet of the main measuring tube body is provided with a measuring cylinder lower electromagnetic valve. A precipitation measuring electrode, an auxiliary electrode and a main measuring tube fault detecting electrode on the main measuring tube body are connected with an electric control measuring cylinder driving board. A control signal output port of the electric control measuring cylinder driving board is connected with a control signal input port of the measuring cylinder upper electromagnetic valve and the control signal input port of the measuring cylinder lower electromagnetic valve. The electric control measuring cylinder driving board is connected with a single-chip microcomputer unit.

Description

technical field [0001] The invention belongs to the technical field of rainfall detection devices, in particular to an electronically controlled measuring cylinder type digital intelligent rain gauge. Background technique [0002] Most of the small automatic weather stations in our country now use the tipping bucket rain gauge, and the tipping bucket rain gauge is greatly affected by the rain intensity because of the inherent defects in the measurement structure design of the tipping bucket rain gauge. This will not only cause errors in the measurement data of the Meteorological Bureau, but also tipping bucket rain gauges are used in some flash flood warning systems. [0003] According to the research, the tipping bucket rain gauge is accurate when the debugging point is 1mm / min rain intensity, and the measurement results obtained under the rain intensity of 2.5mm / min and 4mm / min have a large error, while the 4mm / min The rain intensity is used to debug accurate instruments ...

Problems solved by technology

However, some township-level stations and even some city-level stations did not install automatic rain gauges with high accuracy due to conditional constraints. They still installed tipping bucket rain gauges. It is still equipped with a tipping bucket rain gauge. In case of a heavy rainstorm, the rainfall data will be missed.

When the evacuation of personnel and materials is really needed, people are still kept in the dark, which may cause serious consequences of loss of life and property
