摘要：

为能给判定和调试并条机整体性能提供有效的定量参考数据，开发了一种基于虚拟仪器技术的罗拉同步性检测系统。该系统由采集卡、个人PC机和罗拉转速曲线测试仪组成。给出了基于M/T法的罗拉转速计算方法。利用该方法在LabVIEW平台上设计了罗拉转速检测仪，并将检测系统用于FA1382高速并条机的罗拉转速同步性检测。结果表明：该检测系统可实时检测并条机的各罗拉转速波动情况，获取数据准确，对数据的分析方便、直观且数据通用性较强。通过数据分析发现，这种机型的牵伸性能较好，但其在正常停车时的非线性降速和急停时的降速时间控制有待进一步改进。

Abstract:

A roller synchronization detecting system based on virtual instrument technology is proposed to detect the speed synchronization of rollers of a drawing frame. The system is composted of DAQ cards, PCs and roller speed curve testers. The speed calculation method based on M/T is proposed and the roller speed tester is designed in LabVIEW environment. The detection system bas been successfully used on detecting performance of the drawing frame FA1382. The results show that the detection system can acquire accurate data and data is highly versatile and intuitive. Data analysis show that the drawing frame has good draft performance, but it has also some aspects to be further improved such as nonlinear speed down in normal stop and time control of slowdown in emergency stop. This detection system provides more effective quantitative reference data for judging the performance of drawing frame and improving drawing frame.

Key words: drawing frame, roller synchronization, speed, detecting system, wirtual instrument
