Lightning monitoring and early warning method and system

Abstract

The invention discloses a lightning monitoring early-warning method which comprises the steps of acquiring an electric field signal that is measured by an atmosphere electric field instrument; successively selecting the electric field strength values of three continuous time points in the electric field signal; determining whether the electric field strength value of a last time point in a pre-determining value set is higher than a preset threshold; if yes, determining whether the pre-determining value set accords with a preset condition; and when the pre-determining value set accords with thepreset condition, transmitting an early-warning signal. The invention correspondingly discloses a lightning monitoring early-warning system. According to the lightning monitoring early-warning methodand the system thereof, before the electric field strength which is measured by the atmosphere electric field instrument is compared with the preset condition, the preset threshold is set, and furthermore a lightning early-warning determining method is optimized, thereby greatly improving lightning early-warning accuracy based on the atmosphere electric field instrument equipment.

Description

technical field [0001] The invention relates to the technical field of lightning early warning, in particular to a method and system for improving lightning monitoring and early warning capabilities. Background technique [0002] With the development of economy and modern science and technology, my country's power electronics, communications and aviation have also developed accordingly. However, lightning always threatens the normal operation of electronic equipment. Although some equipment now has corresponding lightning protection devices, because lightning discharges instantly release powerful energy, if electronic equipment is hit by strong lightning during work, the lightning protection device Often can not play a very good protective effect, resulting in damage to a large number of electronic equipment. [0003] In order to prevent lightning damage to electronic equipment, people have established a lightning monitoring and early warning system. When the lightning stri...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the existing lightning monitoring and early warning system only uses the threshold method for early warning, and the accuracy of lightning early warning is low.
