Research And Design Of Smart Home Control System Based On Embedded Linux

With the rapid development of computer technology, automation technology and communication technology trends, smart home has great market prospect. As one of the most popular topics now,smart home will continue to lead the development of the home industry. This paper conducts the research and design of smart home control system,choose the TQ2440 development board of Embedded Sky as hardware platform and choose the embedded Linux operating system as software platform, use Zig Bee wireless communication network to connect a variety of devices together,and use the Qt interface as the human-computer interfaction, choose the Web server and GPRS to realize remote control.This paper respectively made a detailed comparison and analysis of scheme selection from two aspects of hardware and software,and has already given a set of relatively complete solution according to the design of smart home system,the main research contents are as follows:Rebuild my own U-Boot bootloader,Linux-2.6 kernel and YAFFS2 root file system,transplanted and designed relevant drive and test program of peripheral,and designed Qt interface and remote control interface based on Web server,and transplanted madplay background music player on the TQ2440 development board.Made a overall analysis and test according to the realization of those functions,also made a detailed introduction of specific design and transplant process including set up development environment and the use of relevant development tools.Through the serial port,the Zig Bee coordinator communicate with TQ2440 development board and GPRS module.Use the radio frequency identification module as the access control system and use the pyroelectric sensor module for smart switch,in order to realize the control of household appliances through the wall,this paper researched and designed the infrared wireless repeater.
