摘要
为了实现PC机对步进电机的自动调节,设计了基于虚拟仪器技术的步进电机控制方案。系统采用L298N芯片进行驱动,以LabVIEW作为开发平台,并通过串口实现数据通信。结果显示,该系统能够很方便地实现步进电机的转速转向控制,而且利用虚拟仪器开发平台LabVIEW编写上位机程序,具有编程简单,控制界面友好,程序可移植性强的特点。
In order to control the stepping motor automatically,a LabVIEW-based control system for stepping motors was designed.L298N chip is adopted in the system to drive the stepping motors.The data communication between LabVIEW and the microcontroller is executed via serial port.The software and hardware of the system are presented.The experimental results show that this system has a convenient operational interface,and is easy to realize the control of rotate speed and direction.
