Abstract

The invention relates to a precipitation automatic observation device. The device comprises a video camera, a video digital acquisition card, a microprocessor, a transparent ground slide, a shield, a temperature controller, an air nozzle and a floodlight, wherein the video camera, temperature controller and floodlight are arranged in the shield of which top surface is provided with a glass window, the video camera faces to the glass window, the outer surface of the glass window is provided with the transparent ground slide used for bearing precipitation substances, and the shield is connected with the air nozzle used for cleaning the transparent ground slide. The invention adopts a new train of thought and designs the new device which can be used to clearly and conveniently identify various precipitations such as rain, shower, drizzle, snow, snow shower, sleet, sleet shower, graupel, granular snow, ice particles and hail; and the amount of precipitation can be measured and the effect of the device is better than that by using traditional methods.

Description

technical field [0001] The invention relates to a meteorological observation device, in particular to an observation device that can automatically identify precipitation weather phenomena. Background technique [0002] Precipitation weather phenomena defined in the field of meteorology include rain, showers, drizzle, snow, snow showers, sleet, sleet, sleet, rice snow, ice particles, and hail. At present, there are several methods for automatic observation of precipitation phenomenon: [0003] 1. Optical method - particle shading property: [0004] Principle: A laser light source (laser diode) generates a parallel beam, 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 drop of precipitation particle falls through the infrared beam, the received signal weakens. The particle size of water vapor condensate is determined by the degree of dimming, and the speed of condensate decline is determ...
