With the rapid development of communication technology, network technology and intelligence technology, people have increasingly high demand for the comfort and the intelligent level of the home environment, and the ideas and models of household have also taken place in a revolutionary change. Intelligent network entered in the family environment unstoppable. The article use the Bluetooth as the core technology to achieve the system of Intelligent House Network, by comparing the popular wireless technology in current house environment, such as the characteristics and methods of HomeRF,802.11g,WiFi and Bluetooth wireless LAN technologies.In this paper, firstly study the specification of Bluetooth V1.2 system and the main three parts of system structure, which include the underlying hardware module layer, the middle of software protocol layer and user level application layer. Details introduce the design idea and concrete realization method of the hardware and software parts in the system.Then focus on the analysis the construction of house network based on Bluetooth technology, as well as the achieved methods, which include that how to provide centralized voice and data communications, network intelligent control and management of information in the family between the internal and external flows in order to the full realization of data flow and share.Based on the BlueCore03-Multimedia microcontroller and the wireless Bluetooth V1.2 technology, we have designed a wireless Bluetooth system which is working in the 2.4GHz frequency. When we apply the Bluetooth wireless communication to the actual system in the intelligent house environment, people will answer the fixed-line phone easily while they are enjoying the music or chatting with the Skype software, which will bring great convenience to the people's lives.In the end, the conclusion about the performance and key technology of system is made, and point out the problem and the key theory which is waiting to be solved and promoted. The further application is prospected.
