Design of Wi-Fi Based Mobile Electrocardiogram Monitoring System on Concerto Platform

摘要

A wireless electrocardiogram (ECG) monitoring system is developed which integrates Wi-Fi technology. This Wi-Fi based system is comprised of a single-chip ECG signal acquisition module on Concerto MCU, a SimpleLink CC3000 Wi-Fi module and a smart-phone. The Concerto is a multi-core system-on-chip microcontroller (MCU) with independent communication and real-time control subsystems. The data rate of the system is 11Mbps at least and 54Mbps at most. The Wi-Fi module uses infrastructure mode network of IEEE802.11g. Apple's iPhone 4S is selected as the mobile device platform, which embedded with Wi-Fi and iOS. In this paper, the monitoring system is able to acquire ECG signals through 2-lead electrocardiogram (ECG) sensor, transmit the ECG data via the wireless link, process and display the ECG waveform in a smart-phone. The results show that implementation of Wi-Fi technology in the existing ECG monitoring system not only eliminates the physical constraints imposed by hard-wired link but also highly reduces the power consumption of the long-term monitoring system.
