Abstract :
This paper introduces a portable ECG monitor with USB host Interface. This system uses Microprocessor C8051F021 as its controlling core, and SL811HS as USB host Interface chip. Based on this hardware, the paper presents USB host specification stack, specification frame about USB Mass Storage and FAT file system so that the collected ECG signals can be stored in U-Disk without delay. In addition, the ECG signal collection circuit of this system embodies several characteristics including high input impedance, free switch of lead, full filter function and low circuit loss, all of which are quite suitable for portable ECG monitoring system.
