摘要： 由于经济和社会的高速发展，城市的建筑也逐渐变为高楼大厦，那么电梯的重要性显而易见。人们对于电梯的安全性，快速性的要求是越来越高，因此电梯的控制技术也就得到了迅猛发展。近年来，PLC电梯的控制技术越发成熟，再加上西门子推出的S7-1200新型PLC，所以本文是基于德国西门子S7-1200系列和WinCC监控环境系统，并且通过结合电梯的工作原理和控制方法，在电梯仿真EES平台上模拟6层电梯的集选控制系统。PLC程序设计模块化方式中，每层通过从系统的顶层被分成几个模块进程向下，为一个复杂的问题的解决方案。设计的程序能够完成的自动运行功能有：电梯自动运行、内呼外呼信号的登记、记忆以及消除、到层开关门、各种报警指示灯、初始化。由于本系统采用的是西门子的新型PLC，所以会有一个很好的发展前景。52787

Design of elevator collective selective control system
Abstract: Due to the rapid development of economy and society, the city's buildingshave gradually become tall buildings, so the importance of the elevator isobvious.People for the safety of the elevator, the requirement is more and more high speed, so the elevator control technology has been rapid development. In recent years, the elevator PLC control technology more and more mature, coupled with Siemens introduced s7-1200 new PLC, so this paper is based on the Germany Siemens s7-1200 series and WinCC monitoring system and, through a combination of working principle and control method of elevator, elevator simulation EES platform in simulation six story elevator collective selective control system. The design of PLC program uses a modular approach, that is, to solve a complex problem when top-down layer by layer to pide the system into several modules of the process. Design process can be completed automatically function: automatic elevator operation, inside call outbound signal of the register, memory and elimination, to layer opening and closing the door, all kinds of alarm indicating lamp, initialization. Because the system
uses the new PLC SIEMENS, so there will be a very good development prospects.
