基于PCI-1711板卡的驾驶员疲劳监测数据采集系统

Data acquisition system designed for fatigue detection based on PCI-1711

介绍了基于PCI-1711板卡的驾驶员疲劳信号数据采集系统。系统软件采用VB 6.0平台,并采用PCI-1711为数据采集板卡。在详细分析板卡数据采集原理的基础上,调用动态链接库中的驱动函数,通过中断方式进行编程,实现了驾驶员加速踏板位移等信号的采集、显示、保存、回放功能。结果表明,该数据采集系统满足设计要求,可应用于驾驶员疲劳信号的数据采集与监测。

A data acquisition system for fatigue detection based on PCI-1711.PCI-1711 is introduced in this paper.The system software uses VB 6.0 platform and data acquisition using PCI-1711.Based on data acquisition the function of dynamic link library is used to program by the way of interrupt,realizing the action of getting,displaying,saving and replaying analog signal of accelerator pedal displacement for DAQ system,and so on.The result demonstrates that the system could be able to meet the requirements,and will be helpful to monitoring signal in the area of fatigue detection.
