Abstract

A precipitation weather phenomenon collector is composed of a video camera, a video digital acquisition card, a microprocessor, a transparent carrier, a shield, a temperature controller, a wiper, and a lighting lamp; wherein the video camera, the temperature controller and the lighting lamp are placed Inside the protective cover with glass window on the top surface, the lens of the video camera faces the glass window, and the outer surface of the glass window is provided with a transparent carrier for carrying precipitation substances, and the protective cover is also connected with a wiper for cleaning the transparent carrier; The video camera captures the video image of the precipitation material on the slide, and its data interface is connected to the microprocessor through a data cable and a video digital acquisition card. The video acquisition digital acquisition card converts the analog image signal captured by the video camera into a digital image signal and sends it to the microprocessor. device. It can clearly and conveniently identify various precipitation phenomena, and its effect is better than that of traditional methods.

Description

technical field [0001] The invention relates to a weather collector, in particular to a collector capable of automatically identifying precipitation weather phenomena. Background technique [0002] Precipitation weather phenomena defined in the field of meteorology include rain, showers, drizzle, snow, snow showers, sleet, sleet, graupel, rice snow, ice particles, and hail. At present, there are several methods for automatic identification of precipitation phenomena: [0003] 1. Optical method - Particle shading: [0004] Principle: A laser light source (laser diode) produces a parallel beam of light, and an imaging diode measures the energy of the light on the side of the receiver lens and converts it into an electrical signal. When a droplet of precipitation falls through the infrared beam, the received signal is weakened. The particle size of the water vapor condensate is determined by the degree of brightness dimming, and the descending speed of the condensate is dete...
