Abstract: Smart life is different from intelligent items, intelligent scenes, intelligent homes and other products, it is a complex system jointly constructed by people, machines, things, and the environment, and the people, machines, things, and environment that constitute the smart life system are also complex subsystems. Therefore, the technology route of smart life needs to be studied with complex systems theory. In Qian Xue sen system engineering ism, in 1992, Qian Xuesen put forward the methodology of dealing with complex systems, which is "human-machine combination, human-oriented, hall for workshop of metasynthetic engineering from qualitative to quantitative", and pointed out that the main body of solving problems: expert system (human), machine system (machine), and knowledge system (knowledge). Based on the tripartitic intelligent life system composed of people, machines and things, gives the system composition and interaction space of people, machines and environment. By taking knowledge as the main link and key factor connecting people, machines and environment, Qian Xuesen hall for workshop of metasynthetic engineering is constructed, and the theoretical system of intelligent life based on the complex system theory of human body is improved. Focusing on the typical application scenarios of smart life, studies the open complex giant system of people, machines, objects and environment, and gives the smart life system model and typical application based on Qian Xuesen system engineering ism, and provides a new idea and method for smart life to quickly enter the homes of ordinary people, and promotes the development of smart life industry, and helps people realize a better life as soon as possible.
