Recommended lightning warning system

The essence of lightning is that when the electric charge in the lightning cloud constantly changes and increases, the electric field strength will change and strengthen accordingly, so it can be realized by monitoring the change of electric field strength, and analyzing the change trend can predict whether there is lightning strike.

The interaction between solar wind, plasma and magnetosphere constitutes the atmospheric electric field layer between solar wind and magnetosphere. The electric field intensity ranges from +500v/m to -500v/m in weather conditions, and from +2kv to -2kv when thunderstorms are near. The electric field intensity can be increased to more than 15kv when thunderstorms appear. (Note: At different sea level, the value is slightly different)

The occurrence of thunderstorms is relatively complex, but the change process is relatively slow, generally takes about 30 minutes, through the real-time monitoring of the abnormal changes in atmospheric electric field, it is found that the change law of the imminent lightning strike, and comprehensive reference to a variety of data can be analyzed and forecast for thunderstorms.

Lightning early warning system is a fully digital electric field detection and lightning early warning platform, the core electric field detection structure is based on the charge induction principle, the use of MEMS (micro-electro-mechanical system) technology to develop, no motor and other easily worn mobile mechanical parts are notable advantages of small size, low power consumption, good reliability, easy integration. This system optimizes the lightning early warning algorithm by combining electric field differentiation and threshold value. Compared with the traditional threshold value method, it has a greater probability to avoid false alarms caused by human interference (rainy day/strong wind/snow/dust), and further improves the early warning accuracy. Lightning early warning system has the characteristics of accurate early warning, easy networking, easy installation, etc., mainly for aerospace and national defense, meteorology, petroleum and petrochemical, power grid, scenic spot, mining, oil depot, military and other industries atmospheric electric field detection and local lightning short-term warning and other application requirements.
