Problems solved by technology

However, due to the mechanical jitter of the tipping bucket, pulse jitter will appear in the pulse signal output by the tipping bucket rain gauge. When the amplitude of the pulse jitter is large, multiple pulse signals may be generated, thereby affecting the accuracy of rainfall measurement.
[0004] There is no good solution to the above-mentioned technical problem that the tipping bucket rain gauge is disturbed due to the mechanical vibration of the tipping bucket

Embodiment Construction

[0022] figure 1 is a structural schematic diagram of the rainfall measuring device according to the present application.

[0023] refer to figure 1 As shown, this embodiment provides a rain gauge, including: a rain gauge and an interference elimination circuit, wherein the rain gauge 100 is provided with a tipping bucket, and outputs a pulse signal in response to the tilting of the tipping bucket. The input end of the interference elimination circuit 110 is connected to the output end of the rain gauge 100 and is configured to eliminate jitter in the pulse signal output by the rain gauge 100 .

[0024] As mentioned in the background technology, the mechanical vibration of the tipping bucket will cause pulse jitter in the pulse signal output by the tipping bucket rain gauge. When the pulse jitter has a large amplitude, multiple pulse signals may be generated, thereby affecting the rainfall. The accuracy of the measurement.

[0025] To solve this technical problem, the presen...

Abstract

The present invention discloses a tipping bucket rainfall signal acquisition device with an interference elimination function. The tipping bucket rainfall signal acquisition device comprises a rain gauge and an interference elimination circuit, wherein the rain gauge is provided with a tipping bucket and outputs a pulse signal in response to the overturning of the tipping bucket; the input end ofthe interference elimination circuit is connected with the output end of the rain gauge and is configured to eliminate jitter in pulse signals output by the rain gauge. Therefore, the interference ofthe mechanical shaking of the tipping bucket on the collected rainfall signal is filtered.

Description

technical field [0001] The present application relates to the field of rain gauges, in particular to a tipping bucket rainfall signal acquisition device with the function of eliminating interference. Background technique [0002] The observation of precipitation is of great significance to the understanding of meteorology, hydrology, and the safety of aviation and railway traffic. In order to ensure the accuracy of precipitation observation, it is necessary to use a rain gauge for measurement. [0003] Existing rain gauges are mainly tipping bucket rain gauges using standard containers or high-precision containers. The tipping bucket rain gauge outputs pulse signals in response to the flipping of the tipping bucket. The processor receives the pulse signals and counts, thereby calculating rainfall information. However, the mechanical vibration of the tipping bucket will cause pulse jitter in the output pulse signal of the tipping bucket rain gauge. When the pulse jitter has...
