Study On ARM Intelligent Home Control System Research

Internet has become an important channel for the flow of information. Embedded system can connect with the internet to send information to the surface of almost any place in the world. embedded equipment connection with internet represents the real future of the embedded system and networking technology. With IPv6 application, all equipments are likely to have the only global IP address, become internet equipments through the internet IP address.Accordingly, with the development of internet technology and electronic technology, household electronic and electrical products develop towards intelligent and network smart home. Intelligent home integrated with current microelectronics technology and control technology is a typical representative of embedded system.This paper combines power line carrier communication protocol X-10 technology and embedded technology to realize the intelligent home control system,studies the core of the intelligent control system which is the design of hardware and software of intelligent home gateway based on ARM , Smart home gateway is an embedded web server. User lands on smart home gateway to realize remote controlling and operating smart home gateway. Smart home gateway receives user's orders and "translates" them, after that it will send X-10 instructions to the family power line, realize controlling family's equipments.This paper first analyzes the principle of intelligent home control system and X-10 technology , then give us the specific design of hardware circuit based on the ARM platform . This paper designs to the intelligent home control system based on LPC2210 processor, gives the detailed design and process steps of circuit design based on LPC2210 processor. This system main circuit includes power circuit, keyboard circuit, LCD display circuit, memory circuit,network interface circuit, and X-10 power line carrier circuits etc. Second the design of ARM platform software is a focus, In this paper we achieve it in three steps :The first step ,the article on LPC2200 processor realizes embedded operating system uC/OS-II transplantation;The second step realizes TCP/IP protocol stack LWIP transplantation on embeded system;The third step is the form of web server, and design of application software. At last system has formed hardware and software platform ,it enteres a testing link. After the system has run ,we use local oscilloscope to watch the wave form , Then contrast the waveform analysis with X-10 orders, we draw the feasibility conclude which is based on ARM intelligent home control system,Then make the X-10 information appliance and internet in4erconnection control.
