STC89C52单片机脉搏测量仪设计

摘要在人们的日常生产生活中,脉搏测量仪受到了广泛的使用。在现在医院的临床治疗中，脉搏测量就是医生使用最多的诊断方法。最古老的医学治疗的方法就是通过对人体的把脉来判断人体的健康程度，但是它有很多的弊端，比如通过人的感觉和触觉把出来的脉搏准确度是很低的，而且人为因素的影响也是很大的。因此，一种不受外界干扰或者干扰很低的脉搏测量仪需要被人们慢慢的研究出来。这次的了课题设计就是设计一款人为因素干扰小，并且准确度比较高的一种全新的脉搏测量仪。设计的这种测量仪使用的 51 系列的单片型号为 STC89C52 单片机芯片作为这整个系统的控制部分，而对信号的采集使用的是光电反射式传感器 ST188，通过单片机自身就有的定时功能来计算需要的时间。根据 ST188 的感应信号以产生信号脉冲,STC89C52 单片机通过对得到的信号脉冲后沿触发的累加从而计算出人体脉搏跳动的次数,时间是根据定时器的定时得到的。脉搏跳动的次数和时间会在系统运行的时候在液晶上显示出来。73949

Based on the pulse of the single chip microcomputer measuring instrument design

Abstract In people's daily life, the pulse of the measuring instrument has been widely used。 In the clinical treatment of the hospital now, the pulse measurement is most doctors use diagnostic method。 The oldest medical treatment is through the pulse of human body to determine the health of human body, but it has many disadvantages, such as through the person's feeling and touch the pulse of accuracy is very low, and the influence of human factor is also very big。 Therefore, a kind of undisturbed or interfere with low pulse measuring instrument need to be people developed slowly。 The design of the research is to design a small man-made interference, and the accuracy of high pulse of a new kind of measuring instrument。 In the design of the measuring instrument using 51 series monolithic model for STC89C52 single-chip microcomputer as the control part of the whole system, and the signal collection is using photoelectric reflex sensor ST188, through the microcontroller itself some time function to calculate the time required for。 According to the sensing signal to produce a pulse signal, ST188 STC89C52 microcontroller along the trigger signal is obtained by the pulse after the accumulation and the number of human pulse is calculated, the time is according to the timer timing。 Pulse of The Times and time will be displayed on the LCD when system is running。
