摘要
本文提出了一种新型的传统脉搏测试仪的数字化设计---利用高性能光电转换传感装置及信号处理电路、MSP430F2553微控制器、液晶显示器等模块组成智能脉搏测试仪,实现了实时显示被测者每分钟的脉搏数目。电路结构简单,所选器件价格合理,并给出了测试结果 ,达到了设计要求。
The design concept of a novel digitizing method to traditional body pulse tester is proposed. It is called digital pulse tester, which is based on weak signal-amplifying unit, MSP430G2553 micro-controller, LCD and singal-processing unit. Parameters of intput pulses are detected timely with MCU. The structure of this circuit is simple. Results of experiments show that the pulse tester has good performance in some aspcets, such as price, distortion factor, efficiency and so on.
