基于ARM的微弱生理信号采集系统

The Collection System for Feeble Physiology Signals based on ARM

介绍一种基于ARM的微弱生理信号采集系统的研制。硬件系统主要包括干扰抑制电路、滤波放大电路以及LPC2138信号采集电路。基于多分辨率小波分析的信号处理方法,利用LPC2138对采集信号进行处理与分析。实验结果表明,本系统可以实时采集并高精度的还原脑电信号。并且具有体积小,功耗低,性能稳定等优点。

This paper introduces the research of feeble physiology signals based on ARM computer. The main hardware contain： disturbance retraining circuit, and signal collection circuit. The data is processed with LPC2138. It has prevented by experiment that this feeble physiology signals collection system can collect and process physiological signals such as ECG. And it has many advantages such as small volume, low power, steady performance.
