Arm-based Home Automation Systems

With the development of embedded technology, ARM processor is widely applied in the fields of computer, electron and communication with the special advantage, merging network technology, control technology with video monitor technology, to a greater extent, promotes home information and automation. Home automation system based on ARM uses advanced ARM processor as a control platform, comparing to C51, to improve performance and reduce development time; comparing to PC , to balance the system function and save the cost and has very good theory value and prospects home automation.On the basis of analyzing home automation system current status of development home and abroad, this paper adopts advanced ARM technology; gives multi-mode network communications scheme;solves home automation system about different telecommunications network compatibility problem. In the PSTN voice communication, It has put forward communication state machine model, discusses the issues of the phone key detection and overtime no choice, and studies the realization of voice processing technology. In the wireless network communication, it studies the realization of the wireless GPRS communication, to realize the signal transmission between remote user and the system through sending and receiving short messages. In the remote image monitor, it gives the specific methods of realizing capture single frame image, and studies remote network monitor technology under C/S mode. In order to achieve the signal transmission between systems and terminals, it gives the home inner control network interface design scheme, and achieves the appliances control and automatic alarm function. For the system's security problem, it gives the checking identity method. On this basis, it constructs a low cost, high-performance, high reliability of home automation system.
