Integrated lightning early warning system and method

Abstract

The invention discloses an integrated lightning early warning system and method. The system is composed of a lightning detection device, a database processing module and a lightning early warning module. The lightning detection device is used for detecting a lightning signal and sending the lighting signal to the database processing module; the data processing module is used for determining an early warning level of the received lightning signal and a lightning prevention measure corresponding to the early warning level based on combination of a pre-stored lightning level numerical table and a lightning prevention measure table, generating an early warning signal to the lightning early warning module when the early warning level is higher than a preset lightning early-warning threshold value, and generating a lightning prevention measure execution instruction; and the lightning early warning module is used for carrying out alarming based on an early warning signal. Therefore, the provided early warning system has high precision; the early warning time is sufficient; and full coverage of lightning monitoring of a protected area is guaranteed.

Description

technical field [0001] The invention relates to the field of lightning early warning, in particular to a comprehensive lightning early warning system and method. Background technique [0002] With the continuous increase of lightning disasters, more and more units, collectives and various organizations have begun to realize the importance of lightning protection, and in actual work, they have adopted comprehensive lightning protection measures, such as lightning rods, grounding systems, waves surge protection system, etc. These lightning protection devices and systems are designed and used in accordance with the principle of providing a fast and reliable discharge path for lightning current. They all have the opportunity to protect after the lightning strikes. These devices or systems are passive lightning protection. However, in many cases, the most comprehensive protection cannot be achieved because the active prevention of lightning is not considered in advance, and even...

AI Technical Summary

Problems solved by technology

The atmospheric electric field meters in this type of lightning warning system are basically field grinding (mechanical), and its mechanical sensing device relies on a non-hermetic rotating motor that works 24 hours a day to achieve measurement. Ingress or other reasons for failure, damage and other reasons to stop operation, then the sensing device will not be able to provide normal services

At the same time, in order to reduce measurement errors, some components of this type of device must be cleaned and replaced regularly

If in harsh environments more frequent maintenance is necessary

Moreover, during the formation of thunder and lightning, the thunderclouds that produce thunder and lightning are constantly drifting rapidly with the wind speed and direction, causing the local atmospheric electric field to change suddenly, resulting in the problem of insufficient advance time for early warning

Therefore, the ordinary lightning early warning system is subject to certain restrictions on the forecast accuracy and accuracy, and it is prone to false positives and false positives.
