自动双层停车场控制系统设计.doc

内容摘要 随着社会不断进步与发展，人民的生活水平在不断地提高，城镇人口剧增，汽车拥有量日益提高，由于汽车数量的迅速增加，对停车场的需求必将提高，停车难的问题越来越突出。然而地面空间是有限的，特别是对城市已经特别拥挤的地面环境，单城市拥挤的环境已无法提供更多的车位，这就要求车位从地面向空间发展。资料显示全国36个大中城市停车位满足率不足20%，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，因此，车位的空间设计技术就不得不引起人们的注意，车库的合理设计以及怎样控制是设计者最需要考虑的问题。双层立体停车库就是在这种打背景下产生的，该种类型的停车库车位需要完成上下移动和左右移动，这需要一个很好的控制技术，设计者应该根据不同的要求来设计控制系统，以执行一系列的操作。本设计就是针对车库能很好运行来设计的，用PLC来控制，停车库中每一个地面停车位都要有一个停车架，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。 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···················3 2.1 继电器接触器主电路设计·····························································3 2.1．1 继电器接触器主电路中电器元件动作的要求……………………··3 2.1．2 继电器接触器主电路图的设计………………………………………3 2.2 继电器接触器控制电路的设计……………………………………………5 2.2．1 继电器接触器控制电路中电器元件的作用…………………………5 2.2．2 继电器接触器控制电路图的设计··········································· 5 第3章 双层自动停车场系统PLC控制设计………………………………7 3.1 PLC简介………………………………………………………………………7 3.2 PLC的选用原则及本设计PLC实现的功能…………………………………8 3.2．1 PLC的选用原则····································································8 3.2．2 本设计PLC实现功能·····························································8 3.3 自动双层停车场系统PLC控制流程图···············································9 3.4 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··············10 3.5 自动双层停车场系统PLC控制梯形图··············································12 3.6 自动双层停车场系统PLC控制语句表··············································18 结论····································································································21 设计总结····························································································22 谢辞····································································································23 参考文献···················································································
