摘要
介绍了一套基于S3C2440嵌入式处理器和ADS1294模数转化芯片的心电信号采集、处理系统,S3C2440根据ADS1294的工作时序对其进行控制、采样和输出多导联心电信号.S3C2440采用LC/OS-Ⅱ实时操作系统,在接收采样后的心电信号的同时,进行了FIR和IIR软件滤波.最后给出了经过采样、滤波处理的心电波形图,验证了整套系统的可行性.
An ECG acquisition and processing system was introduced, which used the Em- bedded micro-processor $3C2440 and analog-to-digital conversion chip ADS1294. S3C2440 caused ADS1294 to sample and output ECG signal according to ADS1294＇s timing sequence. S3C2440 received the ECG signal and filtered out noises with FIR and IIR in μC/OS-Ⅱ, a real-time system. At last, the final processed ECG waveform was presented, to prove the feasi- bility of this system.
