(In recent years, there has been a new development in intelligent building technology. People have extended the intelligent building technology to multiple intelligent buildings in one area for comprehensive management. Such an area is called an intelligent community. Smart community has become another hot spot in the construction industry after smart buildings, and it is also a bright spot in real estate. The so-called smart community is to use computer technology, communication technology, multimedia technology and other high-tech means to separate the functions of multiple buildings (mainly residential quarters) with the same or different functions within a certain geographical scope. It is intelligent, so that resources can be fully shared and managed in a unified manner. While providing a safe, comfortable, convenient, energy-saving and sustainable living environment, it is convenient for unified management and control, and the performance-price ratio is improved as much as possible.)
