便携式人体脉搏波形测量仪设计与实现

摘要

阐述了基于s3C2440微控制器的人体脉搏波形测量仪的设计与实现方法.从以往人体脉搏波形测量系统的不足出发详细讨论了便携式人体脉搏波形测量仪的硬件组成并给出了软件设计方法.实现了在液晶屏上直接显示脉搏波形,经试验证明这套设计测得的脉搏波形基本达到了标准脉像仪的精度同时也提高了系统的响应速度,且仪器成本低,可靠性高,操作方便.%This article discusses design and realization of human pulse waveform measuring apparatus based on micro-controller S3C2440. In view of the weakness in traditional pulse detecting system, this paper discusses the composition of hardware in portable pulse waveform measuring apparatus in detail and proposes the software design method. Pulse waveform can be shown directly on the LCD screens. The result showed that the pulse waveform measured by this design is basically up to accuracy of standard pulse imager, and it can increase the system response speed.
