基于PLC控制的电梯毕业论文.doc

I 摘要随着经济的高速发展, 微电子技术、计算机技术和自动控制技术也得到了迅速发展, 交流变频调速技术已经进入一个崭新的时代, 其应用越来越广。电梯是现代高层建筑的垂直交通工具,其设计要求稳定性、安全性及高。随着人们生活水平的不断提高, 对电梯的要求的也相应提高, 电梯得到了快速发展, 我国国产电梯多为继电器, 本次设计的软件控制部分由 Verilog 来实现, 研究、分析电梯的逻辑关系,进而实现控制。通过合理的选择和设计,提高了电梯的控制水平,并改善了电梯运行的舒适感,使电梯达到了较为理想的控制效果。关键词:电梯硬件描述语言编译仿真 II Abstract With the high-speed development of economy, microelectric technique , technology of puter and automatic control technology have been developed rapidly, exchange frequency conversion and adjust speed technology and already enter a brand-new era, its application is wider and wider. The lift is the vertical means of transportation of the modern skyscraper, its designing requirement stability , security and high. Living standard constant to raise with people, requisition for lift too corresponding to improve, the lift has got the fast development, the domestic lift of our country is mostly relay control method, the software designed this time is controlled some to realize by Verilog, the logic relation of studying , analysing the lift , and then realize control. Through rational choice and design , have improved the control level of the lift , has improved fort that the lift operates, make the lift reach paratively ideal control result.
