摘 要 蓝牙已经成为便携式设备与台式机外设之间无线互联的一种全球统一的技术标准，它可以使用户不用电缆就能在许多设备之间进行数据交换及文件传输。蓝牙无线技术的目的是取代计算机与外设及电子设备之间的电缆，它工作在全球统一的2.4GHz工业、科学、医疗（ISM）频段，此频段能够使具有蓝牙功能的设备实现全球通用，只要相互在近距离的范围内，就可以实现互联。随着信息家电的不断发展，将蓝牙技术应用于家庭网络具有很大的研究价值和重要性。 本文首先分析了蓝牙技术及其家庭网络在国内外的发展现状。通过比较分析，得出蓝牙技术在智能家庭网关中应用的优越性。然后分析了蓝牙技术规范的体系结构，分析了蓝牙协议、蓝牙剖面以及蓝牙的安全性。 接着对基于蓝牙技术的智能家庭网关进行设计。对智能家庭网关的功能进行了分析，设计了智能家庭网关的硬件和软件系统，分析了信息家电的特点并设计了其结构，最后构建了基于蓝牙技术的智能家庭网关系统。 由于蓝牙模块是实现蓝牙技术的核心部件，本文详细分析了蓝牙模块的组成结构。分析了基带控制器芯片MT1020A以及无线收发器PH2401，通过分析研究，得出由MT1020A和 PH2401组成的蓝牙模块功耗很低，可以应用在很多嵌入式设备中，其次对基于RS232传输层的HCI驱动进行设计，最后对蓝牙模块进行测试，得出蓝牙模块设计的可行性。 最后对全文进行总结，并对进一步研究的问题进行了展望。

ABSTRACT Bluetooth technology has become a global technology specification for “always on” wireless communication between portable devices and desktop machines and peripherals. Among the many things Bluetooth technology enables users to do is swap data and synchronize files without having to cable devices together. Bluetooth wireless technology is intended to replace cable connection between computers, peripherals, and electronic devices. With the development of information electrical appliance, it is valvable and important to apply Bluetooth technology in home network. At first, this paper analyzes the domestic and international development of Bluetooth technology and home network. Through comparation and analysis, it is more superiority to apply Bluetooth technology in intelligent home gateway. Then analyze Bluetooth technology specification, Bluetooth protocol, Bluetooth profiles and Bluetooth security. Then this paper designs Intelligent Home Gateway based on Bluetooth technology. This paper firstly introduces intelligent home gateway and describes its function, then the hardware and software of intelligent home gateway is analyzed and researched. At last, Bluetooth communication system based on intelligent home gateway is constructed. Bluetooth module is the core of Bluetooth technology, so this paper particularly analyzes the struction of Bluetooth module. This paper firstly analyzes the baseband controller chip MT1020A and radio transceiver PH2401 and concludes that the power consumption of the module composed of MT1020A and PH2401 is very low, so it can be applied embeded equipment, then HCI drive based on RS232 transmitting layer is designed. At last, this paper tests Bluetooth module and concludes that it is feasible. In the end, this paper is summarized and the further research is presented.
