Some Investigations For Real-time Monitoring Of FECG

FECG monitoring instrument has high requirements of real-time characteristics,and the performance of the current FECG monitoring equipments on market cannot meet the actual clinical needs.In this paper,it is carried out some research work for the FECG real-time monitoring system,as follows:First,the second chapter studies how to configure the bioelectricity acquisition chip ADS 1298.After summarizing its configuration mechanism,the paper puts forward a kind of specific configuration scheme that is used to acquire normal ECG and its performance is simulated.We also build a real common ECG acquisition system that is based on ADS 1298 and MCU C8051F320 to test the correctness of its configuration.The third chapter studies the construction of rapid prototyping real-time monitoring system based on DSP6678.After summarizing the DSP6678 chip,DSP6678EVM,SYS/BIOS based real-time operating system programming and TCP/IP network communication,the building plan and the related basic programing are designed,and the actual built prototype system was tested,showing that the prototype system runs stably,being able to real-time monitor adults ECG accurately.The fourth chapter studies the common real-time signal processing with the implemented prototype system of DSP6678.First,the program with a single-core is achieved to filter out common interfere in ECG signal,and it is found that the tested DSP processing results are as accurate as the simulation results;then,the programming with the DSP6678 multi-core processing is studed,achieving 8-channel ECG signals real-time processing with 8 cores,and displaying the ecg waveform processed on the upper machine.Finally,the fifth chapter summarizes the full paper,including some disadvantages in research and prospects for further work.
