Problems solved by technology

At present, large-scale fixed umbrellas are often used outdoors to protect the sun and rain. Because they are used outdoors for a long time, the overall volume of fixed umbrellas is generally large. When in use, because of the large volume of fixed umbrellas, it is not easy to open them and requires personnel. When it rains, it is manually supported, and it takes time and effort to open it, which brings a lot of trouble to people's use, so we propose a large fixed umbrella with induction automatic opening and closing
