Research On Embedded Smart Home Control System Based On LINUX Platform

With the progress of the times, people put forward higher requirements for the living environment, a more comfortable, safe, intelligent home system came into being, the computer technology and the rapid development of Internet of Things technology for the emergence of smart home possible.This topic is in the rapid development of Internet of Things technology background of a smart home based on the embedded design. Traditional home environment, the wired connection not only occupy the small part of the living environment of space, but also greatly affect the family environment, the appearance and safety. In this paper, the use of ZigBee wireless communication instead of the traditional wired connection, based on the Internet and embedded technology to build a set of smart home design. At the same time,the use of limited hardware simulation of the home environment of the lights, television, air conditioning, thermometer, alarm equipment. And then joined the camera module, so that users can better grasp the movements of the living environment to ensure safety.According to people's requirements for the living environment and the requirements of intelligent home, the paper puts forward the whole intelligent home model. According to the current mainstream design of smart home, and the needs of this project, the use of ARM CortexTM-A8 series chip S5PV210 as the intelligent home hardware platform and embedded Linux operating system as its software platform .And then build the entire work environment, including the bootloader transplant, Linux kernel customization and migration, and Yaffs2 root file system construction. Next, complete the camera,temperature sensors, infrared sensors, buzzer and other modules of the driver. Finally, the QT is used to complete the picture of the host computer, and the communication with the lower computer is completed by TCP / UDP, at the same time using Web technology allows users to mobile terminals such as mobile phones, tablet login site to view the camera back to the real-time home envirornment and control of intelligent home systems.This topic is based on ARM embedded intelligent home system,the use of ZigBee wireless communication instead of the traditional wired design, to solve the family security risks while also making it more beautiful; Joined the camera module to meet the people around the family for the full range of monitoring, so that the living environment more secure; Using the QT completed the PC screen production, making the human-computer interface more friendly, more portable.
