Piezoelectric rainfall detection device verification system and verification method thereof

The invention provides a verification system and a verification method of a piezoelectric rainfall detection device, the verification system comprises a bearing assembly, a verification assembly and a verification body, the verification body can be used for simulating raindrop falling, the verification body is a solid with consistent size and weight, the problems of inconsistent raindrop quality and water splash are solved, the verification assembly can change the falling height of the verification body, and the verification body can be used for simulating raindrop falling. The momentum of the verification body falling above the detected piezoelectric rainfall detection device is changed, so that various rainfall conditions are simulated; during verification, a falling control channel is arranged in a verification body containing part of the verification assembly and used for containing a plurality of verification bodies, through opening and closing of the falling control part, the single verification body si
