【篇一：电梯毕业设计】
摘要
本文简要论述了当前电梯控制系统的发展现状，并对电梯的控制方
式做了详细的分析，针对现在电梯控制系统的优缺点设计了一个基
于可编程控制的四层电梯控制系统。
本文依照实验室的硬件配置，工程设计的实际要求，针对四层电梯
的控制系统，应用omron公司cpm2a系列plc实现电梯控制系统
的设计，给出了详细的系统设计过程、i/o配置方案、及相应的梯形
图控制程序。该控制系统可以完成电梯的厅外召唤指令、楼层位置
指示等控制任务，并着重的阐述了电梯plc软件设计部分，最后用世纪星组态软件对系统进行实时监控。
本设计采用模块化的编程思想进行设计，按照电梯系统的启动复位
模块，电梯的上下行模块来单独分析。因此该系统具有理解较容易，查找代码及调试方便等特点，并且能很好的达到电梯的各项控制性
能指标，完全可以在实际中进行应用。

abstract
this paper briefly discusses the current development of the elevator control system status, and makes a detailed analysis
of the control mode of the elevator. then design this system of the four-story elevator control system which is based on programmable control, aiming at the advantages and disadvantages of elevator control system.
according to the actual requests of the laboratory’s hardware and the design of this project, this design shows a detailed system design process, i / o configuration and the corresponding control procedures of the elevator’s control
with the use of the cpm2a plc which is made by omron
company to the elevator control system design. the elevator control system realize the duties of the elevators hall
summons the instruction outside, floor location instructions
and focus on the elevator on the plc software design part of
the last century with the system-configuration software to conduct real-time monitoring.
this design uses modular the programming thought to carry on the it, and analysis the start replacement module and ascending-descending module of elevator independently. so the system owns the advantages of more easily to understand and more convenient to find the debugging code, achieving each targets of the elevator’s control performance, fully applied in practice.
