Umbrella With Lightning Strikes Alarm Function

In recent years, the number of lightning strikes has been increasing in Taiwan. At present, Taipower has a complete lightning detection system, which can accurately monitor lightning data. Therefore, this product was an innovative concept invention and design of an umbrella that predicted lightning strikes, helping users solve the danger of being struck by lightning. Meanwhile, the processing unit, the GPS positioning device, the first wireless transmission device, and the warning light device are placed in the space of the umbrella handle. The processing unit used the radar echo tracking information and the transmission information of the GPS positioning device to calculate the motion vector (TREC vector) of each pixel point on the radar echo image. The principle of this technology was to first divide the radar image into multiple small images of the same size. Then, compared and concatenated the two radar images to calculate the center distance position of the rain gear affected by the fall. The first wireless transmission issued a warning sound and light signal that could be received even without a network, increasing the probability of preventing ordinary people, climbers, farmers, and engineers from being struck by lightning. In the end, the product won the silver award in the 4th Green International Invention and Design Competition in 2022.
