Research On Smart Home Network Based On Composite Means Of Communication

With the development of computer technology and the spread of information, a variety of intelligent devices emerged in large numbers, constantly improving the living standards of people. In the same time, people hope to have more and more comfortable home environment. The home environment becomes more humane and intelligent by controlling home equipments and learning at home conditions through remote operations. Under such circumstances, smart home network technology becomes one of the most popular technologies. The so-called smart home generally refers to a variety of family communication equipments, household appliances and home security devices, which connected to a smart home controller through the family bus technology. Then family affairs can be on-site or remote real-time monitored and managed through various means of communication. Mobile GPRS network, the Internet and low-voltage power line have became a distinctive way to transmit various signals.This article focused on and built a basic model of the smart home network. Firstly, some features of each module and the corresponding implementation techniques were studied, and the development environment were also built. On this basis, the means of signal transmission were focused on. This paper presented several possible solutions and implementation details of each solution were described in detail, including GPRS-based transmission, Internet-based transmission and power line-based transmission. Using block-based image data algorithm and the feedback control mechanism, a transmission scheme of embedded image data were designed and implemented, achieving efficient and reliable image data transmission through Internet. Operations of sending, reading and deleting short messages were implemented through network based on GPRS. The solution based on OFDM for low-voltage power line carrier communication technology was proposed, and functions and implementation processes of each module were also analyzed.These options have their advantages. The purpose of the research is to use the advantages of various means of communication so that the appropriate transmission scheme can be selected for different applications to improve system reliability and environmental adaptability. The paper also built a "four networks unifying" basic shape with a unique development and application.
