基于PLC的货物自动识别与分拣系统设计(任务书,开题报告,论文说明书11000字)
摘要
 当今社会，货物的自动识别与分拣系统已经运用到包括交通运输业，商业，邮电通信行业，仓储行业，工程项目，工业过程控制领域和军事设施等各行各业。在给人们带来许多方便的同时还降低了工作人员的劳动强度,减少了劳动力的使用数量。现在生活中的识别系统使用最多的是发展较为成熟的条形码识别技术。组态是利用工业应用软件解决生产过程中的具体任务。组态软件作为一种工业应用软件，是一种监控系统开发工具。它可以通过计算机发出的工作信号对自动化设备或自动化过程进行监控和管理，随着控制系统和组态软件的发展，组态软件由刚开始的单一的人机界面变得越来越大，可以处理的数据量越来越多，在自动化分拣系统的集成中使用越来越广泛，有着重要的地位。PLC作为一种工业控制器，具有不但使用起来非常方便，程序编写简单，而且功能强大，性价比高，在工业控制领域应用广泛。因为其硬件配套比较齐全，用户在使用时非常方便，对环境适应性强，可靠性高，抗干扰能力强等优点也使它比较受欢迎。
本次设计采用PLC与一般条码阅读器和组态王软件组成货物的自动识别与分拣系统，通过给出系统的硬件结构设计、软件设计和系统组态过程，用户可根据自己的需要实时对生产线进行控制和调试，实现数据监控管理，适应现代化生产的需要。

Abstract
In today's society., the automatic identification and sorting system of goods has been applied to various fields including transportation, commercial, post and telecommunications, warehousing, engineering, industrial process control and military facilities. In the people to bring a lot of convenience while also reducing the labor intensity of the staff, reducing the number of labor use. Now living in the identification system is the most used to develop more mature bar code recognition technology. Configuration is the use of application software to provide the tools and methods to complete a specific task in the process. Configuration software is the data monitoring and acquisition system SCANDA software platform tool, is an industrial application software. It can be issued by the computer work signal on the automation equipment or automation process monitoring and management, with the control system and configuration software development, configuration software from the beginning of a single man-machine interface becomes more and more, the data More and more processing capacity, in the automated sorting system integration in the use of more and more widely, has an important position. PLC as an industrial controller, with not only very convenient to use, the program is simple to write, and powerful, cost-effective, widely used in industrial control. Because of its relatively complete hardware support, the user is very convenient to use, the environment adaptability, high reliability, anti-interference ability and other advantages make it more popular.
  This design uses PLC and general bar code reader and configuration software to form the automatic identification and sorting system, by giving the system hardware structure design, software design and system configuration process, the user can according to their own needs real-time Production line control and debugging, to achieve data monitoring and management, to meet the needs of modern production.
Keywords: automatic identification, automatic sorting, PLC, bar code reader, Kingview software
