Home Network And Intelligent Community Integration Program

With the development of micro-electronics, computer and communication technology, the homenet and intelligent community technology has also been developed greatly. HomeNet technology is a hot spot At home and abroad, and "home networking platform" launched by Guizhou Ethernet technology information industry companies was rated as top-class information technology projects with the advanced international level, independent intellectual property rights and prospects market. YT101 field bus used by homenet has been promoting. At the same time, LonWorks bus has been very mature in the application of intelligent buildings, and some intelligent Community have adopted the LonWorks control system. Under such circumstances, this paper researched the system integration of the family network and intelligent community. This paper achieved the interconnection between YT101 control network and bus LonWorks control network by design and development protocal converter.The first three chapter introduced the background of the project, and researched the links of YT101 network and home network and the using of LonWorks network in the intelligent community. The use of home network has just started, and the application of LonWorks is become mature, so the development of protocol conventer is very important to promote home network.In chapter four, it researched the application of LonWorks bus in the building automation. Based on the actual project, it introduced the design of building control system.In chapter five, it researched the development of protocal converter and introduced the communication principle between SCM AT89C52 and the chip of YT101 or 3150. It expounded the hardware design of different module and gave the design process of software.The last chapter is the summary of the thesis and the prospect of the field in the future.
