摘　　要：PSoC3可编程片上系统集成了模拟运算放大器,具有差分功能模数转换器(ADC),数字滤波器,通信串行接口等混合信号处理功能,前端模拟电路设计不需要分立元件搭建,轻松实现人体心电信号采集。本文基于PSoC3 (CY8C3866AXI-040)芯片技术,利用软件分层编程思想,通过可视化的硬件,设计并完成了人体心电信号的采集。与传统分立元件的电路采集系统结果对比结果显示:基于Psoc的系统采集到的信号和传统电路采集到的信号波形一致,但其波形信号噪声较传统电路采集大幅降低。该设备解决了传统分立原件搭建的心电采集电路所需要器件多,电路布局布线复杂,成本高,开发周期长等问题。该设备具有价格低、功耗小、集成度高等优点,在便携式心电图仪设计开发方面具有良好的应用前景。PSoC3 system on programmable chip integrates operational amplifier,and has the mixed signal processing functions,such as differential function analog-to-digital converter(ADC),digital filter and serial interface communication.The front-end analog design of that can easily implement the collection of human’s Electrocardiograph(ECG) signal without need of discrete component building.In this paper,basing on the PSoC3(CY8C3866AXI-040) chip technology and using the idea of software layered programming,the collection of human’s ECG signal was designed and finished in this paper through the visual hardware.Compared with the traditional circuit acquisition system based on discrete components,it can be seen that the signal collected by the system based on Psoc3 is the same as the signal waveform collected by the traditional circuit,but the waveform signal noise is much smaller than the traditional circuit acquisition.It avoids the shortcomings of traditional ECG acquisition circuit,such as many devices,complex circuit layout and wiring,high cost,long development cycle and so on.This system has the advantages of low price,low power consumption and high integration,so it has a good application prospect in the design and development of portable electrocardiograph.
