Design And Implementation Of Smart Home System Based On Embedded WEB And Zigbee Technology

Nowadays, with the rapid development of science and technology and the improvement of people's living standard, more and more people are pursuing the high quality of life.Computer technology and Internet technology gradually applied to life, to provide people with a comfortable, efficient and safe way of life, in the smart home came into being. The use of smart home products to achieve remote monitoring, greatly reducing the operating time,security, reliability, flexibility.Based on the understanding of the current domestic and foreign research status of the intelligent Home Furnishing, according to the current intelligent Home Furnishing functional requirements, the use of wireless sensor network TCP/IP protocol based on ZigBee protocol and connected to design a smart Home Furnishing system, through the test, the hardware and software design is reasonable, can meet the functional requirements of the intelligent Home Furnishing, feasibility high. In hardware design the embedded Web server using the Context-M4 kernel STM32F407 microprocessor as the main controller chip, using LAN8720 as Ethernet control chip Internet ZigBee wireless access network; CC2530 is selected as the wireless communication chip, ZigBee coordinator design, through the serial communication with the Web server, the design of ZigBee router nodes, through the sensor and control module to achieve the monitoring Home Furnishing environmental data and remote control.In the software, build the embedded Web server in the main controller, the C/OS-? operating system transplant, LwIP protocol stack transplantation, Web server program design, web interface design; ZigBee wireless network set up, program design, program design complete coordinator router node. In order to, solve the problem of node routing optimization in ZigBee system in smart home system, an improved routing algorithm is proposed and simulated. At the end of the intelligent Home Furnishing system was tested, including C/OS-? test,transplant LwIP protocol stack transplantation test and Web server test, the test results achieve the desired goals.
