摘 要

在工业控制过程中，经常会有需要精密流程控制的情况，使用人工流水线作业的方法常常会出现错误安装和流程倒错，使得次品率和废品率居高不下，而且无法精密控制产品的质量和各项参数，而且使用人工流水线的成本也比较高昂，这就会导致使用人工方法生产的产品价格高于市场接受价格，从而使产品在市场上缺乏竞争力，而鉴于可编程逻辑控制器的优点，即体积小，造价低，维护简单，可在恶劣环境稳定工作，组态灵活，可靠性高，可控制输入输出模块，可以针对各个生产线做模块化定制等优点，并且具有自动监控整条生产线的功能，在复杂工控和极端环境或者其他需要的特殊生产环境中，使用可编程控制器是最优也是最明智的选择。

在人机交互过程中，经常要用到手动设置工作参数令生产线沿参数循环工作，常规的按钮-LED面板并不能完整和清晰的表现生产线当前的工作状态和将要进入的工作状态，而MCGS （Monitor and Control Generated System）可触摸控制面板即可编程的人机交互控制系统则是基于PLC和嵌入式控制上的软硬件结合系统，其具有完整的人机交互程序、简便的人体工学设计和视觉可见性、易于后期维护的突出特点。

本课题考虑实验性选用了三菱公司的FX3U-40MT型可编程控制器和北京昆仑通态公司生产的可编程的人机交互控制系统软件，其人机交互使用电脑端实现完整功能。使用三菱可编程控制器完成硬件层的机械平台三轴运动控制，使用可触摸控制面板对运行的程序进行检测和实时控制。

本文介绍了可编程控制器，可编程人机交互系统和硬件层的控制逻辑和基本原理，重点介绍可编程控制器和人机交互系统，介绍了完成课题的硬件搭建和软件程序解决方案。本课题基于三菱可编程控制器和人机交互系统设计制作了三轴运动控制装置，该装置使用了三菱公司的FX3U-40MT型可编程控制器进行开发，能够通过显示屏进行手动操作，基础参数设置和系统运行状态监视。

Design of three-axis Motion Control system based on Touch screen and PLC

Abstract

In the process of industrial control, there is often a need for precise process control, and wrong installation and process reversal often occur in the method of manual assembly line operation, resulting in high defective rate and scrap rate. Moreover, the quality and parameters of the products cannot be precisely controlled, and the cost of using manual assembly lines is relatively high, which will cause the price of products produced by manual methods to be higher than the price accepted by the market. As a result, the products are not competitive in the market, and in view of the advantages of the programmable logic controller, that is, small size, low cost, simple maintenance, stable working in a harsh environment, flexible configuration, high reliability, controllable input and output modules, modular customization for each production line and other advantages, and has the function of automatically monitoring the whole production line, In complex industrial control and extreme environment or other special production environment, the use of programmable controller is the best and wisest choice.

In the process of human-computer interaction, it is often used to manually set the working parameters to make the production line work along the parameters. The conventional button-LED panel can not fully and clearly show the current working state of the production line and the working state to be entered, while the MCGS (Monitor and Control Generated System) touchable control panel is a programmable human-computer interactive control system based on the combination of software and hardware on PLC and embedded control. It has the outstanding characteristics of complete human-computer interaction program, simple ergonomic design and visual visibility, and easy for later maintenance.

This topic considers the experimental selection of Mitsubishi's FX3U- 40MT programmable controller and Beijing Kunlun Tongguo Company's programmable human-computer interaction control system software, the human-computer interaction uses the computer side to achieve the complete function. Mitsubishi PLC is used to complete the three-axis motion control of the mechanical platform in the hardware layer, and the touchable control panel is used to detect and real-time control the running program.

This paper talks the control logic and basic principle of programmable controller, programmable system control system and hardware contror, The device is developed using Mitsubishi's FX3U- 40MT programmable controller, which can be operated manually through the display screen, basic parameter setting and system running status monitoring.
