Thunderstorm day automatic recording system applied to meteorological station and recording method thereof

Abstract

Provided are a thunderstorm day automatic recording system applied to a meteorological station and a recording method thereof. The system comprises one or more thunderstorm day automatic recording devices and a remote server. Each thunderstorm day automatic recording device comprises an electrical field planar antenna, a microphone array, a solar cell panel, a GPS antenna, a terminal and a support, wherein the electrical field planar antenna, the microphone array, the solar cell panel, the GPS antenna and the terminal are all mounted on the support. Each microphone array is composed of a plurality of microphones which are symmetrically and evenly distributed on a planar circular array around the support by a certain distance. The thunderstorm day automatic recording devices are in communication with a 3G network through a 3G communication module, and meanwhile the remote server is connected to the 3G network through an INTERNET. The thunderstorm day automatic recording system applied to the meteorological station has the advantages that the happening time and the direction of thunderstorms are automatically recorded, thunderstorm data are sent to the remote server, the starting and stopping time and the starting and stopping direction of each thunderstorm process are counted by the remote server, the year thunderstorm days in an area under administration of an observation station are calculated, the cost is low, and simpleness and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of natural lightning monitoring and protection, in particular to an automatic thunderstorm day recording system and a recording method applied to meteorological stations. Background technique [0002] As an important basic data in the existing lightning protection engineering field and meteorological business, lightning parameters (such as thunderstorm days, lightning frequency, lightning density, etc.) can directly indicate the strength and weakness of lightning activities in a certain area. Among them, the thunderstorm day parameter is the only basic data with long-term records and widely used in existing engineering fields, which is of great value. The parameter of thunderstorm day is widely used in "Code for Design of Lightning Protection of Buildings" (GB50057-2010), such as: [0003] "A.0.2 The annual average density of lightning strikes on the ground should first be determined according to the data o...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the accumulation of regional lightning location data is short. In order to facilitate the reference in the field of meteorological operations and lightning protection engineering under the existing lightning protection design regulations, it is still necessary to use the meteorological thunderstorm day data to extend the grid method to analyze lightning The thunderstorm day data obtained from the positioning data, and the long-term accumulated meteorological thunderstorm day data are the only scale to determine the grid size selection in the grid method

In addition, the grid method cannot avoid the unreasonableness that some observation points of meteorological stations are at the edge of the grid
