[0003] Among them, during the operation of wind farms, lightning monitoring devices will be used to monitor the wind farms for lightning. The reason why wind farms monitor lightning is that lightning strikes pose potential hazards to wind power generation facilities. First, to protect equipment, key components in wind power generation equipment such as wind turbine blades, towers and transformers are very expensive and easily damaged by lightning strikes; second, to protect personnel safety, wind farms are usually located in high-altitude areas or open geographical environments exposed to potential risks of lightning activities; third, to avoid fire risks, lightning strikes can not only directly damage wind power generation equipment, but also cause fires; therefore, through lightning monitoring devices, lightning monitoring of wind farms can effectively warn and respond to lightning risks, protect the safety of equipment and personnel, avoid losses and accidents, and ensure the normal operation of wind farms.
