The Research And Implementation Of Smart Home Management Terminal Based On ARM

Following the "Twelfth Five Year Plan" of the Internet of things marked the strategic key industries, the State Council issued the guiding opinions on promoting the healthy and orderly development of the Internet in February5,2013. Smart Home relying on the Internet of things technology also has increasingly become a hotspot. Combining with computer technology, embedded technology, microelectronic technology, communication technology, sensor technology and multimedia digital signal processing technology, Smart Home management terminal provides such a platform which can be used for control and management of household systems, including Home Furnishing access control security system, Home Furnishing control system, multimedia entertainment system.It is currently required to install multiple control terminal. Systems are not compatible with each other. As the weakpoints exists, such as complicated operation, structural redundancy, complex configuration, in addition to lack of mobility, extensibility, high cost of poor, so it will become unavoidable that we should develop a simple and easy Smart Home management terminal.The research and implementation of Smart Home management terminal based on ARM is discussed in this paper. Embedded ARM9chip S3C2440A is used as the main controller of Smart Home management terminal, and it adopts the centralized management and decentralized control theory in order to avoid dependence on PC machine. Based on modular design, it gives the hardware selection and circuit design of each module, solves the problems such as redundant structure, complex configuration and bad expandability. Combining with typical Smart Home networking technology and analysis of the characteristics of the home internal network information types, it uses Ethernet, GPRS, WiFi and ZigBee as network means of communication of Smart Home management terminal. It can realize remote mobile phone and network control of Home Furnishing equipment, Home Furnishing environment, Home Furnishing security through the mobile network and Internet. It can also realize local control through the touch screen. At the same time, it also solves the problems that cable communication brings, for instance, difficult wiring, the high cost, poor flexibility. The development of Smart Home management terminal software is based on the Windows CE platform which is an embedded real-time operating system. It gives Windows CE5.0operating system kernel cutting, customization, transplantation and Smart Home management terminal application programming. Smart Home management terminal software realizes the function of Home Furnishing control module, Home Furnishing security module, the upper layer communication module and the local control module.
