机电一体化专业毕业论文--基于MCGS挤压机的PLC控制系统设计.docVIP

摘 要 在工业生产过程中，对挤压产品的要求越来越高，传统的机器生产效率低、人工方法生产成本高，这些已经很难达到客户的标准，随着科学技术的进步，企业竞争力的加强，客户越来重视生产效益以及产品的竞争力。而用基于PLC控制的挤压机成为企业降低成本、提高效率和增强企业竞争力的良好选择。 可编程序控制器(PLC)对现场设备的控制极为方便和可靠，在工业控制中得到广泛应用。PLC具有可靠性高、系统设计灵活、编程简单、性能价格比高等优点，但人机界面、数据的分析管理等方面能力较弱，而将PLC控制技术和MCGS组态软件应用于一体的挤压机控制系统，可充分利用二者的优势互补，其可靠性高、控制功能完善、实时性强、用户界面友好。以PLC控制、用MCGS组态来监控这一个完美的组合系统大大地丰富了系统的控制功能，提高了系统的可靠性，同时也引领了工业的时尚化 关键词：MCGS、人机界面 、可靠性、控制功能 Abstract In the industrial production line, more and more high to the request that squeezes a product, the traditional machine production efficiency is low, artificial method production cost Gao, these standards that have already canned hardly attain customer, along with science technical progress, strengthening of business enterprise competition ability, the customer more comes to value production efficiency and the competition abilities of product.But use the extruder controling according to PLC to become a business enterprise to decline low cost, lift high-efficiency and strengthen business enterprise competition ability of good choice The programmable preface controller(PLC) is extremely convenient to the control of the spot equipments and dependable, get an extensive application in the industrial control.PLC has dependable sex Gao, system to design vivid, the plait distance is simple, the function price compare high etc. advantage, but the abilities like analysis management,etc of the man-machine interface, data is weaker, but controls PLC technique and MCGS set Tai software apply to control system at the extruder of the integral whole, can well make use of two of the advantage repair with each other, its dependable sex Gao, the function of control is perfect, solid sex is strong, customer interface amity.Control, use the control function that a Tai supervised and controled this perfect combination system to consumedly enrich system by PLC, raised the credibility of system, the vogue that also guided industry at the same time turned。 Key words：MCGS、HMI、credibility、the functi
