1、 摘 要 随着人们生活的水平不断提高，生活方式、饮食结构不断改变，习惯的变化和 高节奏的生活导致了高血压、冠心病等心血管疾病成为常见病与多发病。要避免和 减少高血压、冠心病这类心血管疾病给人类健康带来的严重危害，有效的旱期诊断 治疗方法和设备，快速的发病后的救治手段都是非常重要的,这些也正是当前广大医 学界专家正在共同努力研究的重点。而脉搏是人体活动最重要、最灵敏和最可靠的 信息源，是反映人体健康状况的重要窗口，而对脉搏的提取速度又快，因此利用脉 搏信号快速的发现病因也是一个有效的方法。 本课题采用嵌入式与无线通讯技术， 提出处理脉信号的新方案,即采集及处理与 无线发送部分（前端系统）+无线接

2、收与 PC 机显示部分（后端系统） 。 前端系统主 要负责脉搏信号的采集和初步处理并发送，能够单独工作；通过无线接收和串口接 口连接到 PC 机上显示， 后端系统主要负责跟踪显示由前端系统传递来的信号。正是 有了无线接收模块的作用，使得系统具备了远程监测的能力。 本文论述了课题研究的现状和意义以及设计方案；介绍了主要的芯片的原理和 他们的使用方法；阐述了硬件设计与软件设计方案； 说明了相应软件的流程和方法， 并解说了相应硬件与软件的调试。最后对所做的工作进行了分析和总结，指出了系 统涵待改进和提高的地方，展望了系统今后的发展方向。 关键词 : 嵌入式系统;无线收发模块;串口;传感器 Abstr
