摘要
目的为进行飞船人工控制系统中作业工作负荷的工效学研究 ,研制一个肌电信号采集与分析软件。方法它是整套实验装置的重要组成部分 ,在微机上实现 ,主要由采集显示程序、分析处理程序以及数据文件组成。结果它能对四路肌电信号、一路操作控制信号进行实时、同步地采集、显示以及离线分析、处理。结论在软件研制过程中 ,通过对视景显示与信号采集任务的分机处理 ,肌电信号与操作控制信号的分频处理 ,采样周期、显示周期、存储周期进行不同设置等技术手段 ,提高软件的实时性。此外 ,它还具有可靠性强、数据精度高、人机界面友好等特点。
Objective A software used for acquiring and analyzing signals was developed for ergonomical research on Human Workload in space manual system. Method As an important part of the whole experimental equipment and being developed in PC, the software is composed of acquisition and display program,analysis and processing program and data files. Result The software is capable of making realtime acquisition and display of four channels of myoelectric potential signals and one channel of operation signal synchronously. The signals are then analyzed and processed off line. Conclusion During the development,its realtime feature was implemented by means of some technical methods,such as that different machine assigned to view scenery display and signal acquisition,different frequency assigned to EMG signal and operation ones,and different cycle assigned to acquisition,display and storage. Above all,with friendly man machine interface and high accuracy of data, the software was even reliable.
