【摘要】：介紹了一種便攜式多路微弱醫(yī)學(xué)生物電信號處理系統(tǒng),用戶可根據(jù)實(shí)際的需要對電極進(jìn)行選擇,從而實(shí)現(xiàn)對腦電或心電信號的實(shí)時采集,進(jìn)而對其進(jìn)行數(shù)據(jù)處理并顯示波形和存儲數(shù)據(jù)。該系統(tǒng)采用德州儀器(TI)公司的ADS1198為核心的模擬前端電路實(shí)現(xiàn)腦電或心電信號的采集、放大、隔離等預(yù)處理操作,利用Altera公司的FPGA芯片Cyclone Ⅱ EP2C70F896C6對數(shù)據(jù)進(jìn)行處理,并在TRDB_LTM液晶屏上顯示波形。該系統(tǒng)精度高、體積小、功耗低,具有較好的實(shí)用性和可擴(kuò)展性。
[Abstract]:This paper introduces a portable multi-channel weak medical bioelectric signal processing system. The user can select the electrode according to the actual needs, so as to realize the real-time acquisition of EEG or ECG signal. Then the data is processed and the waveform is displayed and the data is stored. The system uses ADS1198 of Texas Instruments (TI) Company as the core analog front-end circuit to realize the preprocessing operation of EEG or ECG signal acquisition, amplification, isolation and so on. The data are processed by FPGA chip Cyclone 鈪，
