基于单片机的心率监测系统设计摘要随着社会的进展,心率监测系统已经得到广泛的应用,但医学心率监测系统还存在着单一地点、实时性不精确等缺点。本设计就是为了克服传统心率监测系统的局限性,突出价格低廉、使用简单方便、维护成本低的特点。所设计心率监测系统采纳光学感应原理做成的传感器,把心率信号转换为可测量的电信号模拟量。在CPU的选型上,使用价格低、功能强大的AT89S52单片机。利用中断和定时器功能,能够精确的计算出心率。在做出硬件和完整的软件算法后,进行了多次测试,测试结果表明,本设计能够达到预期的效果。关键词:心率监测系统;AT89S52 单片机;光电传感器 Design of the heart-rate monitoring system based on single chip microcomputerAbstractWith the development of society, The heart-rate monitoring system has been widely used, but the heart-rate monitoring system has a single location, real-time imprecise and other shortcomings. To overcome these limitations of conventional heart-rate monitoring system, highlight the characteristics of inexpensive, easy to use, low maintenance costs, this heart-rate monitoring system made use of an optical sensor, the heart-rate signal was directly converted into the analog electrical signals. Using interrupt and timer functions, this heart-rate was calculated accurately. After making a complete hardware and software algorithms, several tests were achieved. The test results show this design could obtain the desired effect.Keywords:Heart-rate monitoring system; AT89S52; photoelectric sensor 目 录摘 要..............................................................................................................................IAbstract..........................................................................................................................II第 1 章 概述...................................................................................................................11.1 选题的背景和意义................................
