Combined with the embedded operating system ,this paper studies a practical portable ECG signal de-tection system,according to the characteristics of human body biomedical signals ,employing the ARM processor LPC2138 as the core. We designed the circuit of hardware detection, and acquired, amplified and filtered the weak ECG signals,then transmitted them to the ARM processor for processing and analyzing. And the ECG waveforms were displayed on the LCD monitor. Experimental results show that this system can fully detect ECG signals and has strong practical application value.
