1、 Application Environment Description
Atmospheric electric field meterIt is a high-precision lightning monitoring and warning device that can monitor real-time changes in the electric field in the atmosphere, accurately capture the traces of lightning activity, and provide strong support for the prevention of lightning disasters.
In the field of meteorological monitoring, it can be widely applied to meteorological stations to continuously and uninterrupted monitor lightning activity in the region, providing key data for weather forecasting and meteorological disaster warning. By analyzing changes in atmospheric electric fields, meteorological departments can predict the probability, intensity, and development trend of lightning weather in advance, issue lightning warning signals in a timely manner, and provide important reference for the safe operation of the public, aviation, navigation, and other industries.
For various places that are susceptible to lightning strikes, such as petrochemical enterprises, communication base stations, power facilities, high-rise buildings, etc., it can be used as an important monitoring tool for lightning protection. By installing around these locations, real-time monitoring of the dynamic changes in the surrounding atmospheric electric field can be achieved. When the strength of the atmospheric electric field exceeds the preset threshold, an alarm can be triggered in a timely manner to remind staff to take corresponding protective measures, such as stopping outdoor operations and shutting down key equipment, effectively reducing the losses caused by lightning disasters to personnel safety and equipment and facilities.
In addition, it also has certain application value in industries such as agriculture and forestry. In agricultural production, knowing lightning weather information in advance is helpful for arranging agricultural activities reasonably, avoiding crop losses caused by lightning weather, and also ensuring the safety of agricultural workers. In forestry, monitoring lightning activity can be used to prevent forest fires caused by lightning strikes and provide protection for forest resources.
