无线脉搏测量仪的设计

摘要

A new type of wireless pulse measuring instrument is designed. It is measured that instantaneous pulse and average pulse through the collection respondents wrist pulse signal. This device adopts HK2000B pulse sensors to collect pulse signal. Pulse signal after signal processing, including amplifier circuit, baseline correction circuit, band-pass filter circuit, subsidence filter is, plastic circuit, etc. Using MCU calculation and processing, displayed on the LCD panel. At the same time use Wireless module sent to monitoring room. The instrument is easy to use, has the characteristics of miniaturization, good visibility.%设计了一种无线脉搏测量仪，通过采集被测者手腕处的脉搏信号得到被测者的瞬时脉搏数和平均脉搏数。装置采用HK2000B脉搏传感器采集脉搏信号．经过一级放大电路、基线校正电路、带通滤波电路、陷波器、整形电路等送至单片机处理，处理所得的脉搏数据通过液晶屏显示，同时脉搏数据经过CC1100处理发射到监控室，经CC1100接收处理、通过数码管显示。该仪表使用方便，具有小型化、可视性好等特点。
