多通道信号采集与分析系统在冷弯机组中的应用

Application of Multichannel Signal Acquisition and Analysis System in Roll Forming Machine

为提高冷弯机组的控制精度,设计了冷弯成型机组控制系统的多通道信号采集与分析系统。利用高精度传感器测量机组的运动参数,以LabVIEW为软件平台、PXI为硬件平台构建信号采集与分析系统,对各通道的信号进行实时采集、处理与显示,并将所需数据反馈控制系统。实验结果表明:该系统运行稳定,信号采集精度高,并具有易扩展、易维护等特点,适合广泛应用在测控领域中。

A multichannel-signal acquisition and analysis system, which can be used to improve the control accuracy of the flexible roll forming machine is designed. Combing the software platform LabVIEW with the hardware platform PXI controller, the signal acquisition and analysis system is established, and the motion parameters coming from the high precision sensors are acquired, displayed and feedback to the control system for each channel. The experiments showed that the system run steadily, with high accuracy, and easy tobe expanded and maintained, and can be used in the field of measure and control application.
