摘要：电梯这样的运输工具是用于高层建筑中的垂直上下，电梯可以改善人们的劳动条件、减轻劳动强度、加快人们的行动速度。同时电梯在提高人们的生活水平中也有重要作用。
目前电梯的应用范围包括宾馆、商场、医院、住宅小区、办公大楼等。电梯是人们不可缺少的运输工具。有越来越多的人从事着和电梯有关的工作，越来越多的人在为提高电梯的性能做研究，电梯也在快速发展着。
为适应发展的要求电梯的控制系统已经逐渐从微机板控制向可编程控制器PLC控制过度。可编程控制器在电梯控制系统中的广泛应用，是因为它即具有微机控制板的一系列优点同时又可以克服微机控制板的的很多不足之处。更适应现代电梯控制的要求，具有的灵活性也为以后电梯的发展提供了基础。
本次设计中主要完成电梯设计的PLC编程部分，并拿出完整的设计梯形图、指令表、完成调试等。同时对电梯的整体设计，如：电梯的结构、工作原理、各个部件的功能设计要求等也做学习和介绍。通过独立完成此次设计对PLC的编程设计有更深入的了解，在设计中学会解决问题把所学的PLC知识和现实中的电梯控制结合，能根据具体要求完成PLC编程，在调试中发现错误并修正。完成：
1.程序设计的流程图
2.PLC控制的梯形图及程序分析
3.列出I/O接口分布、按钮分布等

Abstract：Elevator means of transport is used for vertical up and down in the high-rise buildings. The elevator can improve people's working conditions, reduce labor intensity and to accelerate the speed of people's actions. the same time the elevator has an important role in improving people's living standards in.
The elevator range of applications including hotels, shopping malls, hospitals, residential quarters, office buildings, etc. The the elevator has become an indispensable means of transport in modern life. More and more people are engaged in related the elevator work, More and more people in research to improve the performance of the the elevator. The the elevator industry is rapidly developing.
In order to meet the requirements of the development, Elevator control system has been a gradual shift from the computer board control to the Programmable Controller (PLC) to control excessive. PLC in the elevator control system, Because it is that has a number of advantages of the computer control panel the same time be able to overcome the inadequacies of the computer control panel. Better adapted to the requirements of modern elevator control, The flexibility to provide a basis for the development of elevator.
This design was completed for PLC programming part of the elevator design, obtained a complete design ladder, the instruction sheet to complete the debugging. the same time in the overall design of the the elevator, Such as: the the elevator structure, working principle, the various components of the functional design requirements to do to learn and introduce. By independent completion of the design more in-depth understanding of PLC programming design, Learn to solve problems in the design, PLC knowledge and elevator control combined with each other. Complete PLC programming according to the requirement, Find errors in the debug and fix.To complete:
1.the flow chart of Program design
2.Ladder Logic, Instruction List
3.Distribution of I / O interfaces and buttons
Key words: PLC；Elevator control；Design
