Problems solved by technology

Most of the sensing technologies mentioned above have no ability to measure the microstructure of precipitation particles and most of the dynamic parameters, so the ability to observe and identify precipitation types is relatively limited, and cannot meet the requirements of replacing manual visual inspection

Abstract

The invention provides a system for automatically observing a precipitation phenomenon based on digital shooting, which comprises a shooting end box body with a shooting opening, a protective cover, a background box body with a background opening, a shooting device, a temperature control device, a light source, a control module, a power module and a computer, wherein the protective cover is arranged inside the shooting end box body, and the end of the protective cover, which is provided with a shooting window made of a transparent material, faces the shooting opening; the background opening is opposite to the shooting opening along the horizontal direction; the shooting device is arranged inside the protective cover and is used for controllably shooting images in a sampling area; the temperature control device is arranged inside the protective cover and is used for adjusting the ambient temperature in the protective cover; the light source is arranged inside the shooting end box body close to the shooting opening and is used for improving the brightness of the sampling area; the control module controls the work of the temperature control device and the light source; and the power module supplies power to the shooting device, the temperature control device, the light source and the control module. The system can acquire a clear digital image of precipitation particles in a natural motion state, analyze the image to obtain the size, shape and other characteristics of the precipitation particles and identify various precipitation types.

Description

technical field [0001] The invention relates to an automatic observation system for weather phenomena, in particular to an automatic observation system for precipitation phenomena based on digital photography. Background technique [0002] Observation of precipitation phenomena has always been one of the most basic observation items of meteorological and hydrological stations. In the "Specifications for Surface Meteorological Observation" promulgated by the China Meteorological Administration, precipitation phenomena include 11 types, namely: rain, showers, drizzle, snow, snow showers, sleet, sleet, graupel, rice snow, ice grains and hail. [0003] At present, there are generally three types of instruments or systems used for automatic observation and recognition of precipitation phenomena: [0004] 1. Sensors based on the observation of mechanical effects of particle motion [0005] Such sensors include acoustic detector (Acoustic detector), piezoelectric sensor (Piezoel...
