资料介绍

脉搏波能反映出人体心血管系统中许多病理的特征,为了快速、便捷测奄人体脉搏,设计一种简易实用的脉搏测量装置。系统硬件以AT89C51单片机为核心,采用HK-2000A传感器采集人体的脉搏数据,软件采用C语言编程,系统将采集的脉搏信号由AT89C51单片机计数运算处理后,再由数码管显示出来。经测试表明,系统相对误差小于2%,符合设计的预期要求。

The pulse wave can reflect many pathological features in human cardiovascular system, in order to measure human pulse quickly and conveniently, the paper designs simple and practical pulse measurement device. The hardware of the system takes AT89C51 microcontroller as the core and uses HK-2000A sensor to acquire pulse data from the human body. Its software is programmed with C language, the system counts and processes the acquired pulse signal by AT89C51 chip microcomputer, then is displayed by the nixie tube. According to the test results, the relative error of the system is less than 2%, it accords with the expected design.
