摘要

Objective：To desgn a pulse wave signal generator to generate pulse waveform signal replacing the actual pulse wave and sending the signal to various types of pulse wave detection systems, debug and check the performance of these detection systems. Methods：The pulse waveform signal generator system which used C8051F020 as its core could obtain the wave data which reflect different physiological states from the PC through the USB interface, and the wave data would be stored. According to the different choice by the people, the wave data would be sent to the special equipments. Results：The pulse waveform signal generator system could conveniently receive the wave data which was sent by the PC, the wave data would be stored on the flash chip, and the pulse waveform signal generator system could send out many kinds of pulse wave. Conclusion：This pulse waveform signal generator system which belongs to the special signal generator system has simple structure and small size. It can easily send a variety of pulse wave signal, and every pulse wave signal reflects different physiological states.%目的：设计一种脉搏波信号发生器,能够发出代替人体实际脉搏波的信号,将其发送至各类脉搏波信号检测仪器中,以求调试和检查这类仪器的性能指标。方法：以C8051F020单片机为核心,通过USB接口连接上位机,获得所需的反映人体不同生理状态的脉搏波波形信号并存储,根据用户的不同选择,将脉搏波波形信号发送到指定的仪器上。结果：该脉搏波信号发生器可以方便的接收上位机发来的脉搏波波形信号,并将脉搏波波形信号储存在自身的Flash芯片中,脉搏波信号发生器可以发送各类脉搏波信号。结论：该脉搏波信号发生器结构简单、体积小,可以方便的发出各种脉搏波波形信号,并且每一种脉搏波信号都反映了人体的不同生理状态,属于专用信号发生器。
