The Design Of ARM-based ECG Acquisition System

With the improvement of living standards, people's emphasis on increasing the health, cardiovascular disease became widespread, regular checks on the heart, is conducive to early detection and timely treatment. so it is very necessary to develope a portable medical costs for reducing the ECG (Electrocardiogram) acquisition system,which has the domestic real-time, convenient, dynamic, continuous ECG monitoring of patients for medical equipment.The main topic is that develope an ARM processor-based ECG acquisition system,which can achieve the ECG acquisition to storage, display, alarm, query and so. and it can make Routine inspection and real-time monitoring to remind to patients for medical treatment early, through the USB interface the host computer can communicate with detailed professional ECG signal analysis and monitoring and provide detailed information for doctors.The topics mainly focused on the design of data acquisition module and data processing module and the Transplantation of system software three parts.In the first,Where the data acquisition module is researched the noise interference of the ECG data acquisition system and suppression of noise and filtering; Second, Data processing module of the ARM processor design memory circuits, peripheral circuits such as serial circuit; In addition, the study of the system is based on embedded Linux system software migration.In the subject, it is making use of the embedded technology in practice, and having a strong practical value in the surgical field.
