摘要
脉搏测量是临床诊断中常用的方法。为了提高脉搏测量的简便性和精确度,设计一种基于51单片机的脉搏测量仪。采用AT89S52单片机进行控制红外传感器作为整个系统的传感器部分,而对于人体心率信号的检测则主要依靠软件和硬件的双重滤波来实现。在人体脉搏跳动明显的地方放置传感器,用按键调节来实现测量范围的调节,其范围精确到2次/min,并进行声音的报警。
Pulse measurement is a commonly used method in clinical diagnosis. In order to improve the simplicity and accuracy of pulse measurement, a pulse measuring instrument based on 51 single chip microcomputer is designed. AT89S52 microcon- troller is used to control infrared sensor as the sensor part of the whole system, and the human heart rate signal detection mainly relies on the dual filter of the software and hardware to achieve. The sensor is placed where human pulse beating is obvious, and the button control is used to achieve regulation of the measuring range, which is accurate to 2 times / min, and with sound alarm.
