specific Embodiment 1

[0036] The guide rail is an aluminum alloy round tube and is oxidized and blackened. It is installed in the middle of the ground of the precipitation weather phenomenon instrument detection simulation environment laboratory that has been built in the Anhui Atmospheric Observation Technology Guarantee Center. It is 10 meters long and 0.7 meters wide.

[0037] Rubber wheels are installed at the bottom of the rail car, which can slide back and forth on the rail.

[0038] The rail car body is processed from aluminum alloy sheet after oxidation and blackening, and the mounting bracket for the equipment to be tested is fixed on the upper surface. The bracket can be used to install the power socket, RS232 communication interface and Doppler precipitation radar.

[0039] An infrared ranging sensor is installed on the left and right sides of the rail car. When the distance to the obstacle is less than 0.2 meters, the brake signal is sent to the controller to avoid collision and damage to the ...

Abstract

The invention discloses a precipitation-category weather phenomenon test device. The precipitation-category weather phenomenon test device has the advantages that Doppler type precipitation radar is fixedly mounted on a track vehicle and can be used for detecting whether precipitation categories such as drizzle, rain and snow occur or not and the starting and ending time of the precipitation categories; the falling speeds of rain and snow particles can be detected by the precipitation radar by the aid of Doppler frequency-shift measurement technologies, and the precipitation intensity, precipitation patterns and the precipitation amounts can be computed by the precipitation radar by the aid of the Doppler frequency-shift measurement technologies; a to-be-detected precipitation-category weather phenomenon instrument is fixedly mounted on the track vehicle, and accordingly weather phenomena can be timely detected; the Doppler type precipitation radar and the to-be-detected precipitation-category weather phenomenon instrument are mounted on the track vehicle, and accordingly the accuracy of precipitation-category weather phenomenon tests can be improved.

Description

Technical field [0001] The invention relates to the technical field of automatic control, in particular to a device for testing precipitation weather phenomena. Background technique [0002] According to the "Precipitation Phenomena Functional Specification (Trial Version)" (November 2013) issued by the Observation Department of the China Meteorological Administration, the precipitation Phenomena needs to be able to detect 5 types of weather including rain, drizzle, snow, sleet, and hail. Automatic observation and recognition of phenomena. As of June 2016, five types of precipitation weather phenomenon instruments have obtained the China Meteorological Administration's special meteorological technical equipment license. According to the construction plan of the China Meteorological Administration's mountain flood project, in 2016, the national ground meteorological observation stations have all installed automatic precipitation observation equipment, with a total scale of about ...
