Abstract
This paper mainly designs an ECG signal acquisition and processing acquisition system, which mainly includes two parts: an ECG acquisition front-end circuit module and a LabVIEW processing and display module. The front-end circuit of ECG acquisition mainly consists of amplifying and filtering modules, which are used to collect and process human signals in real time. In addition, a charging box circuit is designed at the same time, which can charge the ECG monitoring equipment while storing energy and increase the standby time of the equipment. At the same time, the acquired signal is filtered in LabVIEW, and the baseline drift is eliminated to obtain a cleaner and clearer ECG waveform.
