摘　　要：针对目前大多数便携式脑电记录仪只能记录脑电信号,而不能随时查看脑电图的现状,设计了一种基于Android移动设备的脑电记录仪,其中下位机通过高精度的AD转换器将脑电信号转换为数字信号,再通过蓝牙发送给上位机,在上位机对信号进行数据拼接﹑存储和滤波,并绘制出脑电图,实验表明:该记录仪可以准确地进行脑电图绘制,能随时查看脑电图,且体型小巧、携带方便.In view of the most of the present portable electroencephalogram recorder which can any record brain electrical signal, but can′t show the present situation of the electroencephalogram .We designed a kind of any electroencephalogram recorder based on the Android mobile device .The lower computer through high-precision AD converter can convert the electroencephalogram signal into a digital signal , and then sent to the upper computer by bluetooth .The upper computer completes data splice, storage and filter,and then draws out the electroencephalogram signal .The results show that the recorder can draw out the electroencephalogram signal accurately .In addition it is easy to carry with compactsize and to view the recorder at any time .
