The Application And Study Of Bluetooth Technology To Smart Home

Nowadays, the study on home automation and smart home is more and more favored .That how to choose the right technology and method to design a system and suit the situation of our country has become an important task for the real of smart home .Bluetooth technology, a new wireless technology in ISM band, can replace the cable and freely transmit data and voice in short distance .Because of widely supporting ,open standard ,and low power and high security ,now the bluetooth has been accepted by more and more people .The application to smart home is one of the most important applications of Bluetooth, and it drives Bluetooth's development .After analyzing the requirement of intelligent home, a design scheme is presented .We research the key part in it, especially, the Application of Bluetooth technology to Intelligent Home.In this Paper, the first Part is the analyzing of smart home, including their history, future .and all kinds of technology to constructer home network ,on this basis, we select the Bluetooth as the core technology, and we put forward a new concept ,Home Centre controller ,and present a scheme of hardware design in detail The deep research about the Bluetooth protocol is the second part .We research the Bluetooth specification and put forward the development scheme of information appliance ,at the same time design the bluetooth communications software .Finally, we introduce fractal to antenna design, present a method of antenna design and simulate it by ensemble and Ansoft HFSS.The results of experiment show that the smart home system as this paper has strong functions and low price, short development period, convenient maintenance and higher application value .
