MP150系统在眼电信号采集中的应用

Application of MP150 System in Acquisition of EOG Signals

叙述了美国BIOPAC公司MP150多导生理记录仪的软、硬件系统的组成与功能,应用该套系统完成在线采集水平眼电信号和垂直眼电信号,同时在MP150系统的AcqKnowledge 4.0软件平台上解决了眼电信号的滤波处理问题,并分别在离线状态下及在线过程中得到滤波处理后平滑的眼电信号波形,为其他电生理信号的在线采集和实时分析提供了有益的实例,成为日常教学、科研工作的得力工具。

The operation methods on software and hardware system of the MP150 data recorder from American BIOPAC Company are introduced.By the application of this MP150 system,the horizontal EOG and vertical EOG signals are sampled online.The EOG signals are then filtered on the AcqKnowledge 4.0 software platform of the MP150 system.As a result,the smooth filtered EOG signals are got in the offline situation or in the online situation.It is a good example for applications in acquisition and analyses of other bioelectrical signals.Furthermore,the MP150 system has been a powerful tool in the daily teaching and research work.
