基于SOPC的人体脉搏信号的测量

The measure of human pulse signal based on SOPC

介绍基于SOPC并利用PVDF压电传感器对脉搏波信号进行实时采集处理的方案,阐述了系统的设计原理。系统由脉搏信号采集调理电路、SOPC数据处理和上位机测量结果显示3大部分组成。其中在SOPC数据处理部分嵌入32位Nios II软核处理器,用于控制脉搏信号的采集、处理。基于SOPC的人体脉搏信号的测量系统,将所有的接口电路集成在一片FPGA上,系统结构简单,易于升级和功能扩展,具有较高的性价比。

This paper introduce a project about using PVDF piezoelectric transducer to collect and process the pulse signal in real -time based on SOPC, expounds the principles of systems design. The system consist of there major components, pulse signal hardware acquisition and conditioning circuit, SOPC data processing part and the measurement result show on upper computer, in the data processing part of SOPC embedded a 32 bit Nios II soft - core processor using to control pulse signal acquisition and processing. The human pulse signal measure system based on SOPC, integrate all of the interface circuit in a FPGA chip, thus the system structure is simple, easy to upgrade and function expansion, has a high performance - price ratio.
