摘要
随着社会不断发展,电梯在写字楼、公司、宾馆、娱乐场所等高层建筑的应用上越来越广泛。同时随着科技的进步,在计算机技术上,自动化控制方面有着日新月异的改变。电梯已经作为一种重要的交通工具应用在我们的日常生活中,电梯行业也进入到新的发展时期,现如今载人电梯已经成为可以调频调压调速控制阶段,这种控制具有很好的安全性,可靠性,舒适性等特点,现在主流的电梯控制系统是基于PLC的控制系统,并带有人性化的智能控制系统。
近些年来,随着电梯事业的发展,PLC在电梯系统控制上使用越来越广泛,对于西门子公司的S7-300的系统相对于S7-200在功能上更为强大,扩展性更好等方面,本文应用西门子S7-300系统作为电梯控制系统的基础,监控软件技术,通过电梯的工作原理以及工作流程来设计相应的电梯控制系统,设计四层电梯的PLC控制系统。全文主要介绍电梯系统的发展概况、工作原理和组成部分,S7-300这一PLC的介绍,的电梯监控系统设计这几个部分组成。
西门子公司作为一家工控行业世界名列前茅的公司,它的S7-300系统作为一种即经济又切合实际的方案广泛应用在工控行业中,本文设计利用西门子的PLC系统与电梯控制系统相结合,这是一种比较先进的控制系统,有着很好的发展前景。

Abstract
With the continuous development of society, the real estate industry continue to rise, more and more application in pany, office buildings, hotels, entertainment venues and other high-rise buildings more widely. At the same time, along with the progress of science and technology, computer technology, automatic control and power electronic technology also has a rapid change. The elevator has been as an important traffic tool in our daily life, the elevator industry has entered a new period of development, now has e a manned elevator can be FM speed regulator control, this control has the advantages of safety, good reliability, comfort and other characteristics, is now the mainstream of elevator control system the control system based on PLC, and with many user-friendly intelligent control system.
In recent years, with the rapid development of the elevator industry, PLC in the elevator control system is used more and more widely, for the system of SIEMENS S7-300 relative to S7-200 in the function is more powerful and better expansibility and so on, as a basis of elevator control system based on SIEMENS S7-300 system, combined with software to design of the elevator control technology. The system through the working principle of the elevator and the work flow, the design of four layer elevator PLC control system. This paper mainly introduces the development situation of elevator s
