基于PCI-6221和Labview的材料试验机力值测控系统硬件设计

Labview Based on PCI-6221 and the Value of the Materials Testing Machine Force Measurement and Control System Hardware Design

本文针对多台材料试验机同时进行力值测控的要求,采用PCI-6221多功能数据采集卡构成数据采集与控制单元,依托Labview强大虚拟仪器构建和控制功能,实现系统控制。阐述了多台试验机同时进行力值测控的数据采集与控制的设计思路。具有控制灵活、性能稳定、可靠性高的特点,且其采集精度和控制精度达到较高的水平,具有良好的实用价值。

As the requirement of multi-material testing machine to carry out test and control of strength value,, using PCI-6221 muhifunction data acquisition card constitutes a data acquisition and control unit, relying on strong Labview virtual instruments to build and control functions to achieve system control. It described design ideas of several testing machine to the monitoring of value as well as data collection and control. With the characteristics of flexible control, stable performance, high reliability, and its precision and control accuracy of a higher level, the design has a good practical value.
