基于CVI的多通道数据采集系统

Multi-channel Data Acquisition System Based on LabWindows/CVI

基于计算机技术及虚拟仪器平台LabWindows/CVI开发了多通道实时数据采集系统。系统采用ACL-8112PG数据采集卡作为数据采集硬件,与单通道数据采集相比,多通道数据采集需要解决采样速度、各通道数据分离及数据分通道显示等问题。本文介绍了该多通道数据采集系统的结构、软件实现、数据的存储及历史数据浏览。该系统在实际使用过程中取得了良好的效果。

Developing multi-channel real-time data acquisition system based on computer technology and virtual instrument platform. The system adopt ACL-8112PG data acquisition card as data acquisition hardware. Compared with the single-channel data acquisition, multi-channel data acquisition needs resolve Sampling speed, data extraction and show of each channel. In this article, we introduce the structure, software implementation, data storage and storage data check back of this system. We get good result during the usage of this system.
