四层楼电梯的plc控制_毕业论文设计.doc

摘要

此次毕业设计的主要内容有两个，一个是设计出一个能够控制四层楼电梯运动的程序,根据平时所知道的,四层楼电梯分为在1层,2层,3层,4层四个楼层停靠时的其他楼层呼叫的种种情况.这其中也包括了两层同时呼叫以及三层同时呼叫.另一个主要任务是设计出电梯的几个主要部件的零件图以及装配图.其中我主要通过可编程控制器(PLC)来实现四层楼电梯的启停以及那些呼叫的情况.而在电梯的机械部分设计上,我主要将重点放在了电梯的开门机,曳引机以及控制柜上.当然,轿厢,对重这些部件的尺寸也涉及在内.我运用所学知识独立完成了四层楼电梯的机械以及电方面的设计.

Four building elevator design

Abstract

There are two primary coverages in this graduation project, one is to design a procedure which can control this four building elevator. According to which usually knew, four building elevator divides into at one, two, three, four these four floors when other floors call all sorts of situations. This has also included two simultaneous calls as well as three simultaneous calls. Another primary mission is to design the several major components’ detail drawings as well as assembly drawings on the elevator. And I mainly realized the four building elevator’s starting and stoping and those call situations through the programmable controller (PLC). But on the design of the elevator’s mechanical part, I put the emphasis on elevator’s door opener, tactor and cntrol cubicle. Of course, sdan theater box, weight these parts’ sizes also in it. I used knowledge which I have studied to complete the design on mchinery as well as electricity aspect of the four building elevator by my ownself.

Keywords: elevator, programmable controller (PLC), door opener, tactor, control cubicle
