Traditional home intelligent control systems are generally built in a wired manner, such as coaxial cable, USB, CAN bus, and the like. However, wired networks have inherent disadvantages such as wiring troubles and poor scalability, which limits the development of wired network technology in smart home systems. Therefore, based on the Internet of Things, the application of wireless network technology to the home network has become the trend of the times. This is not only because the wireless network has greater flexibility and mobility, it saves the trouble of wiring, and more importantly, it conforms to the communication characteristics of the home control network. The wireless home network condenses the vast space of people's lives and work in the distance that human hands can control.
With the widespread use of embedded systems in the Internet of Things, the smart home control system intelligently controls household appliances and lighting in the home, and achieves home security , and combines other systems to provide residents with a warm, comfortable, safe and energy-saving The advanced and noble home environment allows residents to fully enjoy the convenience and excitement brought by modern technology to life.
