Problems solved by technology
[0003] Raindrops falling on the piezoelectric sensor will generate vibration, the greater the energy of the vibration, the higher the voltage generated on the piezoelectric sensor, so the energy of the raindrop can be calculated by detecting the voltage value output by the piezoelectric sensor, but based on the pressure When the rain sensor with electric effect is used for rainfall monitoring, it is vulnerable to external interference, such as strong wind, dust, fallen leaves and even insects. These interference signals may cause the piezoelectric sensor to detect the vibration caused by non-rainfall as a rainfall signal, resulting in the failure of rainfall monitoring. Inaccurate

The embodiment of the invention discloses a piezoelectric rain gauge interference signal processing method and device and computer equipment. The method comprises the following steps: acquiring vibration information of one or more sensors deployed on a rain gauge; performing parameterization processing on the vibration information to obtain a processing result; inputting the processing result into a classification model to classify vibration signals generated by the sensor by interference signals and normal rainfall so as to obtain a classification result; and filtering vibration information belonging to the interference signal category in the classification result. By implementing the method provided by the embodiment of the invention, the analysis of the vibration signal source of the sensor can be completed, the rainfall types can be distinguished, and interference signals can be screened and filtered, so that the rainfall monitoring precision is improved.
Description
technical field [0001] The present invention relates to a rainfall monitoring method, and more particularly to a method, device and computer equipment for processing interference signal of piezoelectric rain gauge. Background technique [0002] At present, there are a large number of piezoelectric rain sensors on the market. The detection methods are based on piezoelectric elements that convert the vibration signals generated by raindrops into electrical signals, and try to establish a model by measuring the strength of the electrical signals to estimate the impact of each raindrop. Therefore, the total amount of rainfall in a period of time can be further estimated, so as to achieve the purpose of rainfall monitoring. In the market, piezoelectric ceramics are basically used as the sensing unit for the sensing element, and the vibration signal generated by the raindrops falling on the detection surface is detected. To estimate the size of each raindrop, the rainfall is accum...
