PLC在X-Y绘图仪实验设备中的应用

Application of PLC in X-Y plot Experiment Equipment

机电学生普遍存在机强电弱现象,为了让机电学生对机电一体化设备的组成、运行有直观、形象的理解,且能够自由地对其进行装卸,对照机电一体化构成五块论,设计了一典型机电一体化设备-实验室用X-Y绘图仪。该绘图仪动力部分选用易于控制的步进电机,电机驱动放大电路采用抗干扰强、故障率低的集成模块,控制器选用三菱FX2N系列PLC。绘图仪可实现线、三角形、圆、样条曲线图形的绘制。该设备的成功研制不仅让参加者学以致用,亦可促进机电学生学习本专业知识的兴趣。

The students of mechanical-electronic engineering usually have more mechanical knowledge and small electronic knowledge.To let students of mechanical-electronic engineering have a visual and imaginal understand about mechatronics equipment,and freely assemble and disassemble this equipment,due to the five construct theory of mechatronics systems,the X-Y plotter used in lab is designed.Its drive part uses the easy control step motor,the drive and flow up circuit of motor use integration module which has lower fault probability and better anti-jamming capability,and the controller uses FX2N series PLC of Mitsubishi electric corporation.This plotter can draw line,triangle,round,spline and so on graph.The successful development of the equipment can let attendee study and apply it,and can accelerate the interest of mechatronics students to learn special knowledge.
