四层电梯PLC控制及组态 为了提高人们的生活水平和工作效率，人们发明了电梯。现在，电梯成为生活中不可或缺的一部分。本次毕业设计的主要内容是开发基于PLC的四层电梯系统程序，利用计算机与可编程控制器的结合，设计电梯系统的梯形逻辑图，并利用组态软件进行了模拟运行。 围绕这个目标，本文首先介绍了电梯的基本结构，接着论述了各主要环节的控制部分以及控制要求，然后着重介绍了基于PLC的电梯系统程序开发过程，最后通过实训室装置反复调试运行以及进行组态仿真。 经过测试仿真运行，该于PLC的电梯系统程序实现了预期的功能。圆满完成了此次毕业设计的任务。通过这次锻炼，我积累了宝贵的经验，又把以前所学的都熟练应用了一遍，为以后在电梯行业工作打下了良好的基础。 关键词 可编程逻辑控制器(PLC)?? 四层电梯?? ?梯形图程序 组态模拟 The PLC Control System For Four layers of lift control Author：Ji yanchen Tutor：Lin wei Abstract Degree the building is embodied as human civilization sign , it not different with developing a period. In 21 centuries many-storied buildings already can be seen everywhere today. Every big city building having self sign , develops being indicating modern civilization. For the living standard and availability improving people who has invented an electric elevator. Now, the electric elevator becomes the indispensable middle part living. Main time of graduation practice content is the procedure developing PLC-based four tier of electric elevator system, Make use of computer and programming controller union, Design systematic electric elevator echelon logic picture, And, the simulation having been in progress with group state software works. About that this target , the main body of a book have introduced electric elevator basic structure first,proceed to have discussed every key links as well as control section controlling a request , emphasize the process having introduced PLC-based electric elevator system procedure develop , test operation finally by the fact that the experiment device changes over and over again for as well as the group state simulates and then. Procedure has realized the expected function as a result of testing simulated operation , owing the electric elevator in PLC system , has pulled a long finally by assembling an experiment, mission having accomplished this graduation practice run success , perfect on board in experiment. By the fact that this time has taken precious ex
