The Smart Home Control System Based On Embedded Technology

This thesis presented a solution of smart home furnishing system based on embedded system. The system chose the embedded microprocessor, through the ZigBee technology to realize wireless communication between the coordinator and child nodes, completed environmental temperature collection and light, curtain, air conditioning control. The system was included control platform, touch LCD control and the browser control.The system control platform’s main function was to provide users control smart home system, which included hardware platform and software platform. Hardware platform mainly included interface circuit design, such as network module interface circuit and storage module interface circuit. Software platform mainly included loaded bootstrap, burned embedded Linux kernel, made root file system, transplanted Qt software.Touch LCD control was the user through the local manipulation of the smart home system. System client used Qt graphical operation interface, used serial port communication mode and the I/O port multiplexing technology, made embedded control platform and ZigBee coordinator communicate, sent and received data. The underlying drivers wrote a serial port driver module, the serial port driver was loaded into the kernel, realized serial port communication.Based on browser/server work mode, used the browser of computer to realize the smart home system of remote control. Web server in embedded systems was established, used multi-threading technology and communication socket, realized data storage, forwarding and other tasks. Used Web programming technologies wrote programs, the database as the data transfer station, provided data for Web browser display and control function.In the laboratory environment, each function module of the system and the whole system was test. The data showed that meet the needs of system design, implemented the household equipment control, included state control and parameter set.
