| 摘 要： | 设计的动态脑电图记录盒可以记录24h的18导动态脑电信号。采用一种混合信号ISPFLASH微控制器C8051F020控制其采样、存储等所有操作。脑电信号通过前置放大器放大后,由C8051F020内部的12位ADC进行采样。同时可以通过键盘选择一个通道的波形在LCD上显示,以观察系统的工作状况。在系统工作正常后,可以把24h采集到的信号以FAT16的文件格式存储到CF卡中。

| Abstract: | The ambulatory EEG recorder designed in this paper can continuously record 24-hour EEG signals on 18 channels. C8051F020, a kind of mixed-signal ISP FLASH MCU, controls all the functions such as sampling, storage and many others. The 12-bit ADC in C8051F020 samples the EEG signal amplified by the preamplifier. At the same time, the EEG signal of every channel can be selected through the keyboard to be displayed on LCD so that the working status can be detected. After the system is ready, the signals sampled during 24 hours are stored into the CompactFlash card as FAT16 files. |
