Study Of Long-range ECG System With Intelligence

A lot of work have done in remote ECG technology by Domestic and foreign researchers.At first,they transmitted original ECG data to the hospital reception center through radiowaves. However, the method, which is restricted within short distance, is not applicable topatients with heart diseases telemonitoring. In recent years, with the popularization oftelephones, they launched long-distance ECG transmission technology based on telephone, butthis way only applies to a fixed telephone occasions,which is unable to meet requirements ofECG data transmission anytime, anywhere.In view of the current shortage of available products, This paper presents a Remotelow-power ECG monitoring system with intelligence based on GR47, witch is a GSM/GPRSmodule. This system can achieve many functions, such as ECG data acquisition, ECGintelligence analysis, long-range wireless transmission of suspicious data, automatically askingfor help for critical patient and so on. Intelligent data analysis functions can provide apreliminary diagnosis and realize "communicate when abnormal". Thereby, it savescommunication costs and reduces the average system power consumption.The article describes the process of ECG signal conditioning and puts forward animproved ECG amplifier. It analyzes the shortage of traditional ECG arithmetic and putsforward a simplified one and a arithmetic asking for help based on the latter.It also contrasts afew long range communication techniques and stresses the GPRS wireless communicationtechnique and function and application of GR47 witch is a GPRS module.Finally, The author summarizes and expects the foreground and orientation of long-rangeECG system with intelligence in the future.
