Embedded Smart Home Communication Model And Protocol Research And Application

With the wide application of computer technology and development of modern information society and power line communication technology, smart home technology grows more mature. But now in the spreading process, there are still some problems in smart home technology, such as united interface and united protocols. Due to these problems restricting the development and spreading of smart home network heavily, after studying several criteria which most influence home network and are competitive most, network reference model based on home communication technology is produced.Studying existing field bus technology, embedded Internet technology, computer network technology, and power line communication technology, combining computer network structure based on TCP/IP protocol and bus structure based on power line communication by series port communication technology, the hardware system of home network is constructed. The system is brief, sound, of high reliability, and of high stability. It is also convenient, economical, easy to be expanded in function and easy to be spreaded and developed. Studying existing home network protocols, designing adaptable home network protocols for the system, using hardware resources in the laboratory, debug for software and hardware of home network is completed, and real-time monitoring of home network in the LAN is implemented.Home network building and monitoring project is expatiated in software and hardware. The structure of the paper is as follows: Research background is introduced, application field is depicted, embedded Internet technology and power Une communication technology, which are the kernel technology, are analyzed in chapter 1; Existing bus technologies of smart home are analyzed and contrasted in chapter 2; In chapter 3, the hardware platform of the implementation project is introduced in detail, data interaction between home appliances and intelligent chips provides joint less interface for function expanding of home network, using series port communication.
