Embodiment 1

[0092]Referring to FIGS. 1 to 6 , a computer vision-based intelligent rainfall detection device includes a rainfall collection device. The rainfall collection device includes a water container 6 and a tipping bucket 11. The lower end of the water container 6 is provided with a drainage pipe. 8. Below the drainage pipe 8 is a tipping bucket 11. The tipping bucket 11 is installed on the hinge support 12, and the hinge support 12 is located at the position where the tipping bucket can be overturned when the amount of water accumulated in the tipping bucket reaches the set value. . After dumping the water accumulated in the tipping bucket, the tipping bucket is restored to the balance fulcrum of the original position due to the restoring force of the center of gravity. The tipping bucket 11 is installed on the tipping bucket to block the drainage pipe when the tipping bucket is overturned, and release the drainage pipe after the tipping bucket is restored. The stopper 10, the block...

Embodiment 2

[0134] Referring to FIGS. 1 to 6 , the visual sensor of this embodiment adopts a general camera, which is aimed at the small buoy for detection. During design and installation, it must be ensured that the field of view of the camera covers the entire moving stroke of the small buoy. The rest of the structure and working process are the same as in Example 1.

Description

(1) Technical field [0001] The invention relates to a rainfall detection device, which belongs to the application of computer image processing technology, network communication technology, rainfall visualization technology and mechanical design technology in rainfall detection, and is mainly suitable for geological disaster forecasting, meteorology, hydrology, ocean, military, airport, environment, agriculture, forestry, scientific research and other fields. (2) Background technology [0002] At present, the main precipitation sensors are tipping bucket type, float type, and siphon type. These three types of precipitation sensors have not changed in principle and structure for decades. [0003] After decades of development and improvement, the existing tipping bucket rain sensor has been widely used due to its simple structure and no power consumption, and is still used as a recommended sensor for solid-state storage rain gauges. Due to the inherent defects and deficiencies...
