Problems solved by technology
Since the tipping bucket is a mechanical movement, it is inevitable that rainwater will splash and lose part of the rainfall during the turning process. In addition, when the rain is too strong, the tipping bucket may not be able to turn over in time, which may cause further expansion of the error. Regular inspection is required in the application. Clear the debris and dirt in the funnel, screen, and bucket, and regular recalibration is required; technical requirements have some expectations for the accuracy of the weighing rain gauge, and imported products are expensive and difficult to popularize

The invention discloses a high-accuracy waterwheel-type rain gauge and a measuring method. The rain gauge comprises a rainwater collecting device, a waterwheel, induction magnetic sheets and a Hall signal collecting processing circuit; multiple equal-column water tanks are arranged on the waterwheel, the rainwater collecting device is arranged on the waterwheel, rainwater flows into the water tanks of the waterwheel through the rainwater collecting device, and the induction magnetic sheets are arranged on the waterwheel, rotate along with the waterwheel, and are connected with the input end ofthe Hall signal collecting processing circuit. According to the high-accuracy waterwheel rain gauge and the measuring method, from quantizing and collecting, signal processing to remote mobile communication through waterwheel-type dividing grooves, a bran-new rain gauge construction is shown, the rainfall amount and the rainfall intensity can be detected in real time, and the stage rain conditioncan be online forecasted. In the metering process, compared with an existing tipper-hopper and weighing-type rain gauge, the high-accuracy waterwheel rain gauge has creative innovation, through ingenious overflowing design, loss of rainwater is avoided, and the product has the obvious superiority.
Description
technical field [0001] The invention relates to the field of meteorological measuring devices, in particular to a high-precision waterwheel rain gauge and a measuring method. Background technique [0002] Natural rainfall has two sides, it may be a blessing or a disaster; abundant rainfall can provide good growth conditions for crops, but too much may cause floods, landslides, mudslides and other disasters, and too little may easily cause drought In severe cases, it will cause confusion in domestic water, farmland irrigation and factory water, and even lead to land salinization and desertification. Therefore, strengthening the study of meteorological phenomena is the most effective way for human beings to predict and prevent living environment conditions, and accurately measuring rainfall is an important mission proposed by the development of the times for human beings. [0003] On October 30, 2014, the China Meteorological Administration released the "National Meteorologic...
