AUTOMATICANALYSINGSYSTEMOFEEGWITHTHE 8098MICROCONTROLLER

单片微机以其价格低廉、体积小、可靠性高等突出优点日益受到人们的重视，应用十分广泛。目前国内普遍采用的是八位单片机，如ＭＣＳ４８系列、ＭＣＳ－５１系列等。本文介绍了一种用ＭＣＳ－９６系列的准１６位单片机８０９８组成的脑电自动分析系统，它能将对称导联的δ、θ、α和β节律的频率和幅度之分布情况以直方图和数字两种形式由打印机输出，便于医生分析比较，这不仅提高了分析脑电图的效率，而且提高了分析的可靠性。该系统体积小、成本低，便于推广。文章介绍了该系统的硬件和软件的基本原理，对设计技巧进行了分析和讨论。

In China,there are two kinds diagnostics of EEG,the Encephalic Topog-raphy,an expensive equipment,and the manually operated with tedious processand the diagnostic results depended on expertise and experiences of operators.Anew design of automatic analysing system of EEG with the 8098 microcontrolleris described in this paper.8098 microcontroller is a quasi-16-bit microcontrollerdesigned for high speedcontrol functions;It has a powerful ability in data acqui-sition and data handling and a unique performance cost ratio。It ensures that theautomatic analysing system has the advantages of high precision, compact di-mensions and lower cost.The system design consists of hardware design and software design, The re-sults will be printed out by printer. The system has been tested and debugged inlaboratory and in hospital clinic,It worked very well. It becomes a portableEEG,and it can be widely used in most hospitals in China。
