1、立体停车库控制系统的PLC设计立体停车库控制系统的PLC设计摘 要：近几年，随着人民生活水平的提高，及汽车价格的一降再降，有车在老百姓看来已是越来越平常的事。可是，如果你住在一些较老的小区，会发现，买车容易，停车可就难了；更有甚者，有些人为了能在市中心上班地找到一个泊车位，不得不比挤公车起得还早。为什么会这样，这既有历史原因，人们没想到国人会如此快的拥有自己的家庭轿车，也有中国过于太快的城市化，使城市本就薄弱的基础设施捉襟见肘，所以，国家不能承受城市无限度的外扩，也就不允许在每个建筑外面留下大块的空地作为停车场。因此，“车库”是大中城市的热门话题，国家经贸委将“城市立体车库”列为“近期行业技术

2、发展重点”，随着家用汽车的不断增加，公共场所及社区内存车矛盾、车挤绿地的问题将会越来越突出，在人们对生活质量和环境意识不断增强之时“车库”日渐成为热门话题，机械自动化立体车库将会在新开发的楼盘及商业里大显身手。 随着汽车的急增致使城市停车难问题不断恶化,而作为解决城市静态交通的有效措施向空间、向高层发展的自动化立体停车设备,以其占地面积少、停车率高、布置灵活、高效低耗、性价比高、安全可靠等优点,越来越受到人们的青睐。目前市面上常见的机械式立体停车库有：升降横移类、垂直循环类、多层循环类、水平循环类、平面移动类、巷道堆垛类、垂直升降类和简易升降类等8种,其中水平循环类以其结构简单、操作方便、安全

3、可靠、造价低等优点,在国内车库市场占有绝对优势的市场份额。本文介绍了一种由PLC作为主控制器，位于地下2层8车位的水平循环式立体停车库的控制系统，详细论述了其电控系统的软硬件结构，为立体停车库提供了一种新的存储方式。其稳定、可靠、快速、性价比高的特点使得控制系统非常完美。关键词：PLC；立体停车库；升降机；载车板；自动化；车位控制 。 Abstract: In recent years, with the improvement of living standards, and vehicle prices dropped lower and lower, there are car peop

13、人计算机发展起来,也简称为PC;加之可编程序的概念所涵盖的范围太大,所以美国AB公司首次将可编程序控制器定名为可编程序逻辑控制器 (PLC-Programmable Logic Controller),为了方便,仍简称PLC为可编程序控制器。有人把可编程序控制器组成的系统称为PCS可编程序控制系统,强调可编程序控制器生产厂商向人们提供的已是完整的系统了。PLC是以微处理器为基础，综合自动控制技术和通信技术发展起来的一种通用的工业自动控制装置，它具有体积小，功能强，程序设计简单，灵活通用，维护方便等一系列的优点，特别是它的高可靠性和较强的适应恶劣工业环境的能力，使它成为大规模控制工程的理想下位机。1.2 PLC的发展历史自1968年美国GM(通用汽车)公司第一次提出取代继电器控制装置以来,现在已有第五代PLC产品了。PLC除了以连续量为主的反馈控制外,特别在制造工业中存在了大量的开关量为主的开环的顺序控制,它按照逻辑条件进行顺序动作号按照时序动作;另外还有与顺序、时序无关的按照逻辑关系进行连锁保护动作的控制;以及大量的开关量、脉冲量、计时、计数器、模拟量的越限报警等状态量为主
