Key Technologies For Embedded Linux Smart Home System

The development of computer technology and telecommunications technology to facilitate people's lives, but also makes our lives become more and more intelligent, from the first generation of communications technology to the second generation of communications technology to the3G era now and the futureLTE fourth generation of development of communication technology, people innovation of new technologies, and promote the development of human civilization. People can control the handheld device to control his own house lights, electric cookers, water heaters, windows, curtains, air conditioning, etc., the smart home system can have security, if there is any danger, the system will automatically alarm. The smart home system in the developed countries to develop relatively early, while the relatively late development in China and therefore has a huge development of the market, smart home system has a lot of sense.The core of the control of the entire system for the ARM-Linux, the choice of processor manufactured by Samsung ARM11chip, operating system, select a Linux system with a multi-platform, so it ported to the ARM platform is relatively simple, coupled with the system features can be cut, cropped volume to meet the special requirements of embedded systems such platform. This paper first describes the background and significance of the research, the research status at home and abroad, the purpose and significance of the research, then describes the theoretical basis for knowledge of embedded development, including the very mode of operation of the ARM processor, embedded systems and development processes and the basic concepts of embedded Linux. Then a detailed description of the development platform to build, and gives a detailed embedded smart home system, the key technology of wireless GSM concept of operation. Finally, Detailed relevant GSM module operation code and the code.The end of this article were made by the design summary, pointing out the shortcomings as well as improved guidance for follow-up study design.Figure12table14reference4...
