C8051f020 And Usb-based Portable Ecg Monitor

The Portable ECG Monitor Base on C8051F020 and USB is the former detecting equipment belong to Long-Distance Home Health Care System. The research object is to make the equipment collect,storage,display the ECG and it can transmit the ECG data to PC to analyse the data we are interested in using correlation analysis softwares. At the same time ,it can supervise the ECG and alarm in time when detect the unnormal ECG data.The system use embedded MCU C8051F020 and collect the ECG data through former ampliator circuit.The system can storage,display ECG data by flash storage and LCM. Besides it can transmit ECG data to PC through USB.USB supports the plug and play function and three kind of transfer rates LOW-SPEED 1.5Mb/s,FULL-SPEED12Mb/s (USB1.1) and HIGH-SPEED 480Mb/s (USB 2.0). Since the few data connector line and built in error handling and fault recovery mechanism, we can realize conveniency, fast and correctly transmission of ECG data.The whole system is portable and can observe the ECG status at any moment.
