Lightning early warning method and lightning early warning equipment

Abstract

The invention provides a lightning early warning method. The method comprises the following steps: detecting atmospheric electric field parameters of a target space; judging whether the atmospheric electric field parameter reaches an electric field early warning condition or not; if the electric field early warning condition is not met, returning to the step to detect the atmospheric electric field parameters of the target space; if the electric field early warning condition is met, starting a radar to scan cloud layer parameters of a cloud layer; acquiring a cloud layer hazard degree coefficient based on the cloud layer parameters; judging whether the cloud layer hazard degree coefficient reaches a cloud layer parameter early warning condition or not; if the cloud layer parameter early warning condition is met, pushing an early warning signal; and if the cloud layer parameter early warning condition is not met, returning to the step to detect the atmospheric electric field parameter of the target space. According to the lightning early warning method provided by the invention, atmospheric electric field detection is carried out firstly, and then cloud layer parameters are detected by a radar under the condition that atmospheric electric field detection meets preset conditions. Whether lightning early warning needs to be carried out or not is more accurately judged through the comprehensive detection result, and meanwhile the detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of lightning early warning, in particular to a lightning early warning method and lightning early warning equipment. Background technique [0002] Lightning is an atmospheric discharge phenomenon in strong convective weather, with short discharge time and huge energy. The heat energy generated by the powerful current of lightning, the high-frequency electromagnetic field generated by the area around the lightning, and the strong lightning waves can cause huge damage in an instant, causing casualties, damaging communication equipment, destroying buildings, and causing power distribution devices to break. cause a fire etc. Therefore, accurate and timely early warning before lightning occurs is of great significance to the protection of people's lives and property. However, the formation of lightning is affected by many factors, such as the geographical and geological characteristics of the area where it occurs, climat...

Problems solved by technology

However, the formation of lightning is affected by many factors, such as the geographical and geological characteristics of the area where it occurs, climate characteristics, changes in the surrounding environment, etc., as well as the instantaneous characteristics of lightning, all of which bring difficulties to the accurate warning of lightning

At present, the atmospheric electric field instrument is used to detect the intensity of the atmospheric electric field for lightning warning, but it is difficult to accurately locate the specific location of lightning, which leads to the inaccurate and timely lightning warning
