基于PLC控制自动售报机系统毕业设计论文.docxVIP

自动售报机毕业设计论文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；The newspaper vending machine graduation design thesisABSTRACTThis article will introduce the newspaper vending machine system based on single chip microcomputer control motor sell newspaper, This system mainly consists of two parts: One is the front desk the vending system, Second is background management system, Coordinate with each other between the two systems can make the newspaper vending machine function is more perfect, Make the operator to operate more simple and convenient. From the developing trend of the newspaper vending machine, it is because the labor-intensive to technology-intensive industry structure the product of social transformation. At present, due to the huge number of population, Lead to a sharp rise in the number of production and consumption, consumption patterns and consumption environment also changed accordingly, which requires new circulation channels to appear on the market.Originally the newsagent cannot meet the needs of customers, the newspaper vending machine under such conditions make it arises at the historic moment. The newspaper vending machine using PLC control makes the system more stable and ensure the newspaper vending machine is a long-term and stable run, And PLC control not only can realize the control function, but also has high reliability, easy programming, good maintenance, etc. This article will from all parts of the appearance and it expounds on the function, analyzed the structure of its hardware and software. Will also to a transaction process of newspaper vending machine working process in detail.Key words:The newspaper
