1、倏4猫义人牵毕业设计题目:_ 电梯自动控制系统设计学生:庞金明学号:2013031202专 业:机械设计制造基础及自动化指导教师:陈婵娟陕西科技大学职业教育师范学院2017年6月3日电梯自动控制系统设计摘要随着我国经济的高速发展,微电子技术、计算机技术和自动控制技术也得到了迅速发展,交流变频调速技术也已经进入一个新的时代,其应用越来越广。而电梯作为现代高层建筑的垂直交通工具,与人们的生活日益紧密相关。随着人们对其要求的提高,电梯技术得到了快速发展,其拖动技术已经发展到了调频调压调速,其逻辑控制也由PLC代替了原来的继电器控制。本次设计的研究题目是“电梯自动控制系统设计”主要是利用PLC及其软件
2、来实现电梯信号的控制,其控制的核心是PLC。课题研发的主要任务和内容是:熟悉电梯的主要组成部分、工作过程及对电梯整机的性能指标要求;制定单梯控制系统总体方案,绘制控制系统总框图;电梯曳驱动系统原理图及选型设计;PLC控制系统硬件设计、I/O分配及程序设计;程序调试与仿真;轿厢系统的三维模型设计。对于这次设计中的两个核心问题,一个是运行效率和安全性的要求,另一个是利用PLC实现电梯的信号控制。针对这两方面问题,在这次设计中通过对编程器的合理的选择和程序的正确编写,使问题得到了解决。关键词:PLC控制;变频调速;电梯;舒适感Design of elevator automatic control
