The Design Of Smart Home Based On ZigBee

With the increasing living standard, people require better living environment, especially home environment. How to improve home environment and make it more comfortable and safer is a big problem for engineers. Under this background, the idea of'Smart Home'was raised firstly in some foreign countries, and some famous building adopt this idea.The core of this idea is to use computer technology and communication technology to improve home environment. In our country, this idea was introduced recently, so the application level of our smart home is much lower than foreign countries'. But we can not deny that smart home has a bright future in our country, what we are lacking of are mature products and solutions. In this paper, a solution of smart home system is proposed.In this paper, the major work was done as follows:1. The current situation and communication technology of smart home at home and abroad have been introduced, by comparing them, we choose ZigBee wireless communication technology as our smart home communication method.2. The origin of ZigBee technology has been introduced in detail, and the protocol of ZigBee has been researched.3. The circuits of ZigBee coordinator, router and end device have been designed.4. The modulate circuit and control circuits of smart home sensors have been designed.5. The smart home control center circuits and remote alarm circuits have been designed.6. The software of ZigBee wireless network device has been developed on the basis of Z-Stack.; the embedded OSμC/OS-II has been ported in smart home control center, and the function of smart home is realized by adding tasks toμC/OS-II.7. Some test and certification has been done on the ZigBee development platform.
