基于PLC的全自动剪板机系统设计论文.doc

PAGE 基于PLC的全自动剪板机系统设计 摘 要 文章对我国发展低成本自动化的重要性等方面进行了研究。以工业用剪板机为对象，探讨了全自动剪板机智能控制系统的实现方案。根据实际需要和市场的需求，在常规的可编程控制器（PLC）和单片机控制中，选择了以可编程控制器为主的控制方案。 由于自动剪板机是一种可按加工要求，将金属板材剪开、自动计数、并由送料车送到下一工序的顺序控制的设备。它要求其控制设备具有很强的抗干扰能力，而PLC是近几年发展起来的一种新型工业控制器。由于它把计算机的编程灵活、功能齐全、应用面广泛等优点与控制器系统的控制简单、使用方便、抗干扰能力强、价格便宜等优点结合起来，而其本身又具有体积小、重量轻、耗电省等特点，在工业过程控制中的应用越来越广泛。加之PLC以其在硬件设计中采用了屏蔽、滤波、光电隔离等技术，在软件设计中采用了故障检测、信息保护与恢复等措施，进一步提高了PLC的可靠性。文章中采用了以工业顺序控制过程中广泛使用的可编程控制器（PLC）对自动剪板机进行控制。通过对自动剪板机的工作原 理的分析，提出总体设想，初步设计了电气传动部分的设计方案和PLC控制的程序流程图。 关键词：可编程控制器 全自动剪板机 自动控制 顺序控制 Abstract Article develop to our country low cost automatic importance ,etc. respect carry on research. Regard industrial board cutting machine as target, probe into full-automatic to can cut board quick-witted realization scheme of the control system. According to the real demand of and the market, in the regular programmable controller (PLC ) and one-chip computer control, have chosen the control scheme relying mainly on programmable controller . Cut board machine whether one can according to requirement of processing , cut off , count , and give metal panel skip send order apparatus that control of process the next automatically automatically. It requires its apparatus of control to have very strong anti-interference ability , and PLC is the controller of a kind of infant industry developed in recent years. Because the programming of a pair of computer of its is flexible , and controller control of system simple easy to use, anti-interference ability strong, price getting cheap advantage combined together, and it has characteristics such as small , light , power consumptive provinces ,etc., the application in the industrial process is controlled is more and more extensive. In addition PLC adopt , shield , strain wave , photoelectricity person who isolate technology in hardware design with their, have adopted measures such as detection of trouble , information protection and resuming ,etc. in software design, have further improved the dep
