基于三菱L-PLC的电子槽轮实验台设计

Design of electronic groove wheel experimental platform based on Mitsubishi L-PLC

设计了一种基于工控产品的槽轮实验台,以触摸屏作为人机界面,PLC作为逻辑控制核心,运动控制模块输出定位数据至伺服驱动器,执行对两个伺服电机的定位控制。其中一个电机连接拨盘轴,用于演示传统机械式槽轮机构的运动规律;另一个电机连接位于槽轮上方的指示盘轴,用于展示电子槽轮的输出特性。通过独立运动与同步运动的对比实验,学生在进一步掌握槽轮的结构性能与运动规律的同时,也能初步了解以PLC为核心的工控系统的组成要素与控制方法,深入体会机电一体化的概念。

A groove wheel experimental platform based on the industrial control product is designed.The touch screen is used as the man-machine interface,PLC is used as the logic control core,and the motion control module outputs the positioning data to the servo driver and carries out the positioning control for two servo motors.One motor is connected to a dial shaft to demonstrate the motion of a conventional mechanical groove wheel mechanism,and the other is connected to an indicator disk shaft above the groove wheel to show the output characteristics of the electronic groove wheel.Through the comparative experiment of the independent movement and synchronous movement,the students can know well about the structure performance and movement law of the groove wheel,and preliminarily understand the composing elements and control methods of the industrial control system with PLC as the core,and deeply understand the concept of mechatronics.
