双层自动停车厂控制系统设计.docVIP

内容摘要 当今世界，如何迅速对应变革时期所发生的环境变化，以成为能否保持稳定经济增长的关键所在。在众多新情况中，如何良好地解决城市泊、叫车问题，已成为建设一个现代化城市必须解决的课题。在我国停车设备的研制才粗语起步阶段，随着小汽车不断进入家庭，停车难的问题将日益突出。双层立体停车库就是在这种打背景下产生的。它是一个以地面停车位为相对独立的单元进行设计的。停车库中每一个地面停车位都哟一个停车架，停车库的下层装有可以动的停车地板。在存、取车时，上停车地板仅作垂直升降运动，下停车地板制作水平移动。呼叫车时，下排车位只需直接将车子直接开出即可，如要呼叫上排车位车子，只要按下1至3的按钮，再按下【叫车】按钮，则所按车位将降至下层，而下排车位将左右移动，让出位置让上层车位降下。控制部分采用继电接触器控制或者采用PLC控制。例如叫1号车只需判断4有、无车，然后根据存车状态，利用系统对地面车左右动作，1车再垂直下移，实现自动叫车。 关键词：自动；双层停车；PLC控制；继电器接触器控制 目 录 第1章 引言·····················································································1 第2章 双层自动停车场系统继电器-接触器控制设计···················2 2.1 继电器接触器主电路设计··························································2 2.1．1 继电器接触器主电路中电器元件动作的要求…………………2 2.1．2 继电器接触器主电路图的设计…………………………………2 2.2 继电器接触器控制电路的设计…………………………………………3 2.2．1 继电器接触器控制电路中电器元件的作用……………………3 2.2．2 继电器接触器控制电路图的设计·····································4 第3章 双层自动停车场系统PLC控制设计…………………………… 6 3.1 PLC简介………………………………………………………………… 6 3.2 PLC的选用原则及本设计PLC实现的功能…………………………… 6 3.2．1 PLC的选用原则····························································6 3.2．2 本设计PLC实现功能·····················································6 3.3 自动双层停车场系统PLC控制I/O地址分配表和I/O接线图··········7 3.4 车辆存取流程图·······································································9 3.5 自动双层停车场系统PLC控制梯形图··········································11 3.6 自动双层停车场控制系统PLC语句表··········································17 结论···································································································· 21 设计总结···························································································· 22 谢辞···································································································· 23 参考文献···························································································· 24 第1章 引言 实现自动叫车是城市的社会、经济、交通发展到一定程度产生的结果，立体叫车自动控制的发展在国外，尤其日本已有近30-40年的历史，无论在技术上还是在经验上均已获得了成功。我国也于90年代初开始研究开发自动叫车系统，距今已经近几十年。这项研究具有很大的现实意义和潜在的市场经济效益。 控制要求：1、双层自动停车场上
