Research On ECG Detection Technology Based On Bluetooth Communication

The ECG signal is one of the bio-electricity signals studied by human,but also one of the main indicators of heart disease detection,and the acquisition and data transmission of ECG signal is one of the key points of human research.Therefore it is of great significance to study the key technologies of ECG detection.In recent years,the rapid development of embedded technology and Bluetooth technology provides a good technical support for this kind of research.Based on the significance of ECG detection,the mechanism of ECG waveform generation,the common interference in the detection,lead mode,AD8232 integrated front end,STM32F103C8T6 chip,Bluetooth 4.0 technology and communication in the key technical analysis based on the overall Design,put forward and designed a portable ECG detection system.The research on the collection,processing and transmission technology of human ECG signal is focused on the transmission of data and the configuration of upper and lower computer,as well as the detection of signal loss in ECG signal,signal acquisition,amplification filter and data Transmission for research.In order to deal with the signal effectively,the circuit filter and the digital filter are combined,and the amplification filter circuit is designed.In the system software,the shedding detection circuit is designed.On the data transmission,the data of the ECG Sent to the host computer forprocessing,analysis and comparison,and finally introduced the specific implementation of the system.The main research contents are:(1)Design and implement ECG acquisition circuit,central control circuit and related functions.ECG acquisition circuit mainly includes the reference voltage buffer,off detection,right-leg drive and amplification filter circuit,etc.The central control part mainly includes the selection of the main control chip,the peripheral interface circuit,the micro-controller minimum system,and other circuit design.(2)Design and study the software part of the whole system,including the off detection,digital filtering and Bluetooth communication.Describe the process of sending and receiving data and the configuration of upper and lower computer.Test the system function and do some analysis and research on the data.
