| With the rise of people's demand on inhabitancy environment, homeintellectualized has become the inevitable trend of the development of dwelling house.Smart home is rising in our country, but it not really walking into people's life all thetime, that's because there are many problems existing, such as the price, thepracticability and the function.For this purpose, this paper mainly researched a scheme of smart homelong-distance control which based on embedded system, it has lower cost, and is easy tooperate, and suitable for the rebuild of old building. The research including the designof whole system, constitute the hardware and program the software.First, the paper introduced the developing status and trend of smart home techniqueall over the world, and analyzed the problems about smart home in China, confirmedthe direction of research; then according to the requirements of system, created adeveloping platform based on LPC2210 processor andμC/OS-Ⅱoperation system; aftercomparing several kinds of schemes, I designed a long-distance control system whichcombined telephone long-distance controller, GSM short message warning and webserver surveillance, realized the conformity of in-home control subsystem, homewarning subsystem and meter reading subsystem, and put forward a method oflong-distance reading meter based on GSM network. The paper also compared somenetworks of home, and designed a centralized home network combining the wire modeand wireless mode, the last part of the paper introduced the transplant ofμC/OS-Ⅱandthe design of software, and the system achieved the performance desired after debug. |
