With the development of intelligent buildings, electrical installation and construction technology has become a key link affecting its later use. In the traditional building electrical construction, the electromagnetic equipment is mainly used to control and adjust, so it is not only difficult to operate, but also has large safety risks. However, the electrical in intelligent building mainly uses optical fiber cable to control and detect various equipment, which to a large extent improves the efficiency and quality of electrical installation and construction. Therefore, it is of great value and function to analyze and study the electrical installation and construction of intelligent buildings.
