The Design Of Smart Home Based On ZigBee Technology

With the progress of science and technology, people’s pace of pursuing toward high-quality living is more and more quickly. In order to have a better living environment, people have never stopped. It has brought unprecedented opportunities,which is to use technology to change the life style of the intelligent Home Furnishing.Because of the huge demand space for intelligent Home Furnishing, there are a lot of people to join the ranks of the intelligent Home Furnishing. As a result, the competition is bound to increase, and also the phenomenon promotes the development of intelligent Home Furnishing industry rapidly.First to compare of the three kind of wireless communication technology,Bluetooth, Wi-Fi and Zigbee, finally it is concluded that the Zig Bee technology relative to the other two kinds of communication technology has the advantages of low cost, fast in network, good scalability, low power consumption and many other features. Thus Zigbee becomes the core technology of the intelligent system design of Home Furnishing. In this paper, there is combined with the principle of sensor, the principle of embedded system, the Zigbee wireless communication technology and other aspects of knowledge. Using fully compatible with the 8051 kernel with researched and developed by TI Company, supporting IEEE802.15.4 protocol of wireless radio frequency- CC2530 chip MCU at the same time, based on CC2530,Home Furnishing intelligent control system is researched and designed. This paper will be divided into four parts: The first part, it sketches the background of the topic,and the foreground and background of the development of intelligent Home Furnishing. The second part, it generally introduces in the analysis of system requirements and constructs the design of system, then introduces in Zigbee technology. The third part, it is how to complete the hardware circuit design and select the sensor. The last part, it completes the software design and the writing of the program, then realizes the function of the system of the intelligent Home Furnishing.This subject conducts a comprehensive analysis of the demand for smart HomeFurnishing system, and then according to the demand of the system, the following functions of Home Furnishing system are designed: lighting control, combustible gas detection, temperature and humidity detection, infrared alarm and so on.
