Title ECG Information Collector Design For Detecting Sub-health State

Abstract

Sub-health problem is a major health problem in society nowadays. ECG information can effectively reflect the health of the human body. It is meaningful to design a simple, rapid and reliable ECG information collector for monitoring sub-health.

Based on the characteristics of ECG information, the disposable soft electrode has been selected as sensor and the ECG signal conditioning circuit has been designed. The ECG signal is amplified and filtered. The MSP430F5525 microcontroller has been selected as the master chip combining with FM25L256.The data has A/D converted and stored and then through the Bluetooth has transmitted wireless. The software design is included lower computer software based on the C language and PC software based on LabVIEW, which has made the data A/D conversion, data storage and waveform display realized.

It has been proven that the system can achieve ECG information effectively.
