Lightning Location Instrument Achieves Low False Alarm Localized Short-Term Lightning Warnings Using MEMS Technology

The lightning location instrument is a fully digital electric field detection and lightning warning platform. Utilizing MEMS technology and optimized warning algorithms, it reduces false alarms in windy, rainy, and dusty environments. It can be deployed in a network and is suitable for short-term lightning warnings in power grids, mines, oil depots, and other fields.

The lightning location instrument is a fully digital electric field detection and lightning warning platform. The core electric field detection structure relies on the principle of charge induction and is developed using MEMS microelectromechanical systems technology. The entire device has no easily worn moving mechanical parts such as motors. It features small size, low power consumption, high reliability, and easy integration, making it suitable for long-term continuous operation in various outdoor industrial scenarios.

This system uses a lightning warning algorithm optimized by combining electric field differentiation with threshold values. Compared to traditional methods that rely solely on threshold values, this effectively reduces false alarms caused by environmental factors such as rain, strong winds, snowfall, and dust, improving the overall accuracy of lightning warnings. The equipment relies on the acoustic, optical, and electromagnetic field characteristics generated by lightning radiation to remotely measure various parameters of lightning discharge and acquire real-time data on changes in the atmospheric electric field, thereby determining the development status of thunderstorm activity.

The lightning location instrument consists of a lightning warning probe, a data processing host, a solar power supply system, a surge system, a grounding system, temperature, humidity, and air pressure sensors, a three-level audible and visual alarm, and a cloud-based data query and display module. The equipment's electric field measurement range is -100kV/m to 100kV/m, with a resolution of 0.1V/m and a detection radius of up to 15km. The sensor weighs 710g, and the entire unit weighs 36kg. These hardware parameters meet the requirements for large-scale localized lightning monitoring.

The lightning location instrument supports network operation, has a simple on-site installation process, and is suitable for atmospheric electric field detection and short-term lightning warning needs in various industries. It is widely used in aerospace, defense, meteorology, oil and petrochemical, power grids, scenic areas, mines, oil depots, and other locations. In practical deployment, the solar power system can ensure continuous operation without external power supply points, the surge and grounding system ensures the safe operation of equipment during thunderstorms, the audible and visual alarms provide on-site graded alarms, and the cloud module can remotely retrieve real-time monitoring data to help managers deal with the safety risks brought by lightning in advance.
