基于虚拟仪器的多传感器通道数据采集系统设计

摘要

针对多通道传感器数据采集存在测量数据量大、繁冗,读取数据误差大等问题,提出了一种基于虚拟仪器LabVIEW平台的多传感器通道数据采集系统.从传感器和信号调理方面给出了系统实时数据采集系统.在此基础上,完成了对LabVIEW软件部分的采集程序设计,以及实时数据采集系统的设计,最终实现了该系统的多通道数据采集.通过对多通道数据采集系统进行调试试验,可知测量精度满足多通道数据采集系统要求.%Aiming at measuring multi-channel sensor data acquisition data such as large error link problems,it presents a LabVIEW-based virtual instrument platform for the design of multi -channel data acquisition system. It proposes the data acquisition system diagram of the overall design aspects of sensor,designs the collection of the LabVIEW software programming,and develops the real -time data acquisition system, realizes the multi -channel data acquisition function of the system.The multi-channel data acquisition system for debugging test, measurement accuracy satisfies the requirement of multi -channel data acquisition system.
