Example Embodiment

[0020] The following describes the invention in further detail with reference to the drawings and embodiments:

[0021] See figure 1 , The present invention includes a planar capacitive liquid level sensor and its signal conditioning circuit 1, A / D conversion circuit 2, microprocessor 4, watchdog circuit 3, liquid crystal display circuit 5, communication circuit 6, control interface circuit 7, real-time clock / Calendar circuit 8 and electric regulating valve control circuit 9.

[0022] Such as figure 2 , image 3 As shown, the capacitive liquid level sensor 17 of the present invention is fixed inside the rain collector 10. The rain collector 10 is made of insulating material. The rainwater enters from the water inlet 18 of the rain collector 10, and the water outlet pipe 14 of the rain collector 10 is provided. There is an electric regulating valve 15 with an adjustable opening, and the rainwater in the rain collector 10 can be discharged through the electric regulating valve 15...

Abstract

The related hyetometer comprises: a rain collector with a water outlet pipe, a capacitor-type liquid level sensor, and a signal process circuit. Wherein, on the pipe, it arranges an electric control valve with input end control ends connected to the signal circuit and a control circuit with output end connected to the control end of valve. This invention realizes dynamic measurement, and can avoid information loss in draining.

Description

technical field [0001] The present invention relates to a rain gauge. Background technique [0002] At present, domestic and foreign meteorological stations (stations), hydrological observation stations, agricultural and forestry systems, and relevant railway departments mostly use tipping bucket rain sensors or capacitive rain sensors to measure liquid precipitation. Compared with traditional rain gauges (barrels), Its main advantage of this type of device is that it can automatically and continuously detect the size of rainfall, but its structure is complex and expensive. Contents of the invention [0003] The present invention provides a rain gauge with simple structure, accurate measurement, high performance-price ratio and convenient adjustment for the above-mentioned various rainfall detection devices. [0004] The technical solution provided by the invention is: a rain gauge, including a rain collector, a liquid level sensor and a signal processing circuit thereof,...
