弯曲智能化控制系统中基于LabVIEW虚拟仪器高速数据采集的实现

The realization of high-speed data acquisition on the basis of LabVIEW virtual instruments in the bending intellectualization control system

采用有效测试手段,实时监测能够反映被加工对象特征的力学参数和几何参数是板材成形智能化4个基本要素中最重要的一个环节。本文应用虚拟仪器技术,以LabVIEW作为系统控制软件,以便携式计算机,6062E便携式数据采集卡,信号调理4槽机箱、8通道应变测试调理模块、8通道模拟输出调理模块等作为系统硬件实现了数据的高速采集。本文主要介绍智能化弯曲系统实时监测要素中的基于LabVIEW虚拟仪器的高速数据采集的实现。

Monitor in real time is the most important link during the 4 basic key elements in the intellectualization of sheet metal forming, which adopts effective test means to reflect the mechanics parameter and geometry parameter of the processed target＇s characteristic. It is well realized for high-speed data acquisition using virtual instrument technique based on LabVIEW as the system controlling software and using the system hardware composed of the portable computer. 6062E portable data acquisition card, four-slot chassis for signal conditioning, eight-channel module for strain-gauge and eight-channel module for analog output is given in this paper.
