An embedded service system based on Bluetooth technology was proposed, aiming at real-time service for mobile personnel. The system can provide timely services for users who have smart mobiles with blue tooth. The system consists of smart phones, Bluetooth wireless servers and background equipment, Svtem functions and work flow were described. Key techniques were mainly analysed for the key system deviee~the,Bluetooth server. Hardware design was discussed in detail based on ARM 32bits microprocessor and CSR BIueCore4 Bluetooth module as well as software design based on Linux operating system cut out and Bluetooth protocol. Experiment results show that products baaed on described techniques can meet the actual requirements.%提出了一种对流动人员进行即时服务的蓝牙嵌入式服务系统模型.系统能够对拥有如蓝牙智能手机的用户提供即时信息服务.系统由蓝牙智能手机、蓝牙无线服务器及后台设备组成.阐述了系统主要功能及系统具体工作流程,重点分析了系统核心设备-蓝牙服务器设计所用的软硬件关键技术.详细论述了基于ARM32bits微处理器XScale和蓝牙模块CSRBlueCore4的硬件设计和基于Linux操作系统裁剪及蓝牙协议的软件设计.实验及应用结果表明,依据所述技术设计的产品能够满足实际要求.
