In today's society, with the improvement of the quality of life and the acceleration of the pace of life, people's work and life become more information-based. The information society has changed people's way of life and working habits, and made the intellectualization of home system become the demand of consumers, while the intelligent home system is becoming more and more popular. Therefore, it has become a hot research topic in recent years to integrate various communication devices, household appliances and home safety devices into home devices through house control systems and remote control and management.

So far, there is no universally accepted and unified definition of smart home. Generally, smart home systems use advanced computer and network communication technology to organically combine various subsystems related to home life through specific networks, and make home life more comfortable, effective, safe and energy-saving through scientific management.


It is an efficient, comfortable, safe, convenient and environment-friendly living environment that takes the residence as a platform, combines building, network communication, information appliances and equipment automation, and integrates system, structure, service, management and control. Smart home includes intelligent lighting, electric curtains, background music, security alarm, building intercom, remote control, etc.

The traditional home intelligent control system is generally built in a wired way, such as axis cable, USB, CAN bus, etc. But the wired network has the inherent shortcomings of troublesome wiring and poor scalability, which limits the development of wired network technology in smart home systems. Therefore, based on the Internet of Things, it has become a general trend to apply wireless network technology to home networks. This is not only because the wireless network has greater flexibility and mobility, saving the trouble of wiring, but also because it conforms to the communication characteristics of the home control network. Wireless home network condenses the vast space of people's life and work into the distance that can be controlled by human hands.

With the wide application of embedded systems in the Internet of Things, smart home control systems can intelligently control the household appliances and lighting in the house, and achieve family safety precautions. Combined with other systems, they can provide residents with a warm, comfortable, safe, energy-saving, advanced and noble home environment, so that residents can fully enjoy the convenience and splendor of modern technology for life.

Smart home networks can generally be divided into home data networks and home control networks: home data networks that provide high-speed data transmission services, such as personal computers and digital televisions, video and audio players, resource sharing and broadband Internet access; Home control network for home lighting, home safety, home surveillance and emergency home assistance.
