The Smart Home Controller Designed Based On Power Line Communication

Smart home is a specific form of Internet of Things under the Internet technology. The equipment in a home is connected into a network through the technology of smart home with Internet of Things.Smart home provide People with more comfortable and safe life,at the same time to achieve the effect of energy conservation and environmental protection and purpose.At the recent years, smart home is becoming more and more rich with the development of Internet of things.In this paper,author design the controller base on Power Line Communication of LonWorks bus with the ARM embedded technology. Using the PL3120which is the chip of Echelon company as the processor of Power Line Communication, and using the S3C2440as the main control chip. Focuses on smart home system information collection, processing and network transmission problem.The focus of this paper is to introduce the composition and principle of the smart home controller that with the power carrier communication and ARM technology. Transplantation the μC/OS-Ⅱ on the S3C2440, design a variety of functional tasks,. Establish the LonWorks network by the technology of LonWorks Bus. The communication medium is power lines. Communication mode is power line carrier.Works in this paper:(1)Study the composition and principle of smart home control system;(2)The hardware of the Smart Home controller design, including the control circuit with S3C2440, Network communication circuit with PL3120, and the electricity acquisition circuit with ADE7753;(3)The software of the Smart Home controller design, including the transplantation μC/OS-Ⅱ, design the application tasks of the operation system and PL3120program;(4)Build the LonWorks control network, to realize data sharing and PC monitor.
