（2015届） 毕业设计（论文） 柔性加工系统PLC控制系统综合程序的开发 所在学院 铁道供电与电气学院 班 级 铁道供电121 姓 名 马健 学 号 201213230138 指导老师姓名 华满香 完成日期 2014年12月 摘 要 可编程控制器（programmable logic controller ，简称PLC）是以微处理器为基础，综合了计算机技术和自动化技术而开发的新一代工业控制器,它具有可靠性高、适应工业现场的高温、冲击和振动等恶劣环境的特点，已成为解决自动控制问题的最有效的工具，是当前先进工业自动化的三大支柱之一。 当今，科学技术飞速发展，人类活动给世界带来了巨大的改变。在科技进步的同时，以各种控制器控制的不同类型的机械手以其突出的性能所以被越来越多的被人们所应用。机械手在不同的作业场合，尤其是在特殊的环境背景下，为人类活动的快速进行带来了极大的方便和益处，尤为明显的是在工业领域内。工业中大量的生产活动，存在着很多不便于人类操纵的环节，特别是在工作环境较危险的情况下，如果使用具有远程控制功能的机械手，则可以增加系统的安全性，大大的节约损耗，提高效率。可见，在自动化、工业化进程中，在特殊背景环境中使用机械手已成为一种必然的趋势。 关键词：PLC，机械手，步进电机，触摸屏 ABSTRACT PLC (programmable logic controller, hereinafter referred to as PLC) is based on microprocessor, a combination of computer technology and automation technology and development of a new generation of industrial controller. It has high reliability, to adapt to the industrial field of high temperature, impact and vibration, etc. The characteristics of bad environment, has become the most effective tool to solve the problem of automatic control, is one of the three pillars of the current advanced industrial automation. In todays society, science and technology rapid development, human activities create world a huge change. In the meanwhile, technological progress in various controllers different types of manipulator with its outstanding performance more and more used by people. The homework in different occasions manipulator, especially in the special environment context for the human activity quickly smoothly caused great convenience and benefit, particularly obvious in the industrial and military field. Industrial large Numbers of production activity, there are many not it is easy for humans to manipulate the link, especially in a business environment is dangerous situation, if use has remote control functions may be increased manipulator, the s
