1、基于PLC控制的自动售报机系统摘要本篇文章将介绍基于PLC控制的自动售报机系统，这个系统主要是由两个部分组成：一是前台售报系统，二是后台管理系统，这两个系统之间相互协调使得自动售报机的功能更加的完善，操作者操作起来更加的简单便利。从自动售报机的发展趋势来看，它的出现是由于劳动密集型的产业构造向技术密集型社会转变的产物。在现阶段，由于人口的数量巨大，导致生产消费的数量也急剧上升，使得消费模式和消费环境也发生了相应的变化，这就要求市场上出现新的流通、售卖渠道。原来的那些报刊亭已不能满足顾客的需求，自动售报机在这样的
2、条件促使下便应运而生。自动售报机使用PLC控制使其系统更加稳定，保证了自动售报机能够长期稳定的运行，而且PLC控制不仅能实现控制功能，还具有高可靠性、易编程、好维护等特点。本文将从外观和它的各个部件的功能上进行阐述，分析它的硬件和软件的结构。关键词:自动售报机；PLC；单片机；控制系统；45/45ThenewspapervendingmachinegraduationdesignthesisABSTRACTThisarticlewillintroducethenewspapervendingmachinesys
