摘　　要：介绍了一套基于虚拟仪器技术的应用系统,该系统可以应用于步进电机扭矩的测量。系统对步进电机及其驱动电路进行实时检测,实现了驱动电压和步进电机绕组电流的多通道同步数据采集与状态分析,并将分析结果反馈至控制主机,控制主机根据反馈结果做出相应的决策。系统还实现了步进电机零位的模拟控制和实时监测。基于虚拟仪器技术的应用系统为LAMOST光纤定位系统稳定、可靠地运行提供了保障。This paper presents an applied system based on virtual instrument technology. The system can be applied to measuring the torque of any stepping motor and is also used to realize the multichannel data acquisition and status analysis. The analysed results are fed to the main controlling computer, which can make a corresponding decision according to the analysed results. Besides, the system can perform the simulation control and realtime test of the stepping motor for its zero-point. Such an applied system ensures stability and reliability to the LAMOST optical fiber positioning system.
