摘　　要：人体的脉象中包含丰富的信息,如心脏、内外循环和神经等系统的动态信息等。而脉搏的病理生理性改变,常常引发各种心血管事件。脉搏生理性能的改变可以出现先于疾病的临床症状,通过对脉搏的检测可以对如高血压和糖尿病等引起的血管病变进行一系列的评估。主要介绍了数字式脉搏计的具体实现方法。利用红外传感器产生脉冲信号,经过放大整形后,输入单片机内进行相应的控制,从而测量出一分钟内的脉搏跳动次数,快捷方便。通过观测脉搏信号,可以对人体的健康进行检查,通常被用于保健中心和医院。系统主控芯片采用STC89C52,可以把采集到的脉搏信号显示在LCD1602上。除此外,系统还可以通过DS1302读取实时时间并显示。Human pulse is rich in dynamic information about the heart,internal and external circulation and nervous system. Pathophysiological changes often lead to a variety of cardiovascular events,while the pulse changes in the physiological performance can appear before the clinical symptoms of the disease. Vascular disease caused by hypertension and diabetes can be assessed by pulse detection.This article mainly introduces the concrete realization method of the digital pulse meter. It uses infrared sensor to produce pulse signal,after amplification plastic,inputs accordingly control for single chip microcomputer to measure a minute pulse frequency. By observing the pulse signal,the inspection on the health of human body,used in health care centers and hospitals,can be conducted. The master control chip of the system,using STC89C52,can put the collected pulse signal in the LCD1602 display and read and display the real- time by DS1302.
