【摘要】 信息时代最大的特点就是进行更方便快速的信息传播,随着计算机与通信设备种类和数量的日益增多,这些设备间的连接和通信就显得至关重要。有线连接已经不足以满足人们随时随地便利通信的期望,无线通信以携带方便、无需布线、成本低等优点被越来越多的运用。目前已经存在很多成熟的短距离无线接入技术标准,包括IEEE802.11、蓝牙(Bluetooth)、HomeRF等。结合当下短距离无线技术发展的实际要求,论文首先进行蓝牙无线接入系统关键技术的研究,在此基础上提出了蓝牙数据接入网关的总体设计方案,规划了系统的应用场景,确立了蓝牙终端通过网关接入以太网以及GPRS网络的功能；然后详细分析硬件平台的设计与实现,包括嵌入式微处理器模块、存储器模块、蓝牙收发模块、以太网接口模块、GSM/GPRS模块、蓝牙终端模块六个部分；其次构建系统的软件平台、进行软件模块的设计与开发,包括进行Linux操作系统和BlueZ协议栈的移植,设计核心控制模块、蓝牙协议栈、GSM/GPRS三大部分的软件流程并具体实现；最后实现了以网关为核心的蓝牙无线接入系统,系统中蓝牙终端通过网关成功接入以太网和GPRS网络,从三个方面测试系统的性能,并对测试结果进行详细分析。更多还原

【Abstract】 The biggest characteristic of this information age is more convenient and rapid information transmission. With the increasing number and types of computer and communication equipment, the links and communication between these equipments is essential. Cable connection has not enough to meet the expectations of people whenever and wherever possible to facilitate communication. Wireless communication with convenient carrying, no wiring, low cost is more and more applied. There have been many mature short distance wireless access technology standards, including IEEE802.11, Bluetooth, HomeRF and so on.Combined with the actual requirement about the development of short distance wireless technology, Firstly, we studied about the key technology of Bluetooth wireless. After that we proposed the overall design scheme of embedded Bluetooth data access gateway, maked a detailed planning for the general design of the system,so that through the gateway Bluetooth data terminal can be connected to the Ethernet and GPRS network function. Next we did a detailed introduction about the hardware platform design and Implementation,including embedded microprocessor module, Bluetooth transceiving module and so on. And then we designed for software platform. Fist,we transplanted Linux operating system and BlueZ protocol stack, Second we designed software flow of the core control module, Bluetooth protocol stack, GSM/GPRS Bluetooth protocol stack and GSM/GPRS. Finally, we realized the gateway as the core of the Bluetooth wireless access system, in the system Bluetooth terminal successful access Ethernet and GPRS network through the gateway, and analyzed this system performance test results in detail.更多还原
