摘要随着经济社会的不断发展,越来越要求机器智能化,从而达到节省人力资源,提高经济效益的效果,在这个大背景下,国家邮政局决定启动邮政营业系统和王云系统互联工程建设,在邮政全网范围内,对邮件实施网络化作业模式。
本文的要实现控制系统的总体功能是识别、接收和处理分拣信号,根据分拣信号的要求,指示分类装置按商品品种、按商品送达地点或按货主的类别对商品进行自动分类。完成控制系统的选型和设计,实现对邮件分类装置、输送装置以及分拣道口的控制;具体内容包括控制系统硬件配置和应用程序开发以及完成变频调速系统设计。23319 毕业论文关键词:邮件分拣机 PLC 变频
Ring Distributed Mail Sorting Machine Control System Design
Abstract
With the continuous development of economic society, the machines are increasingly required to be intellectualized in order to save the human resources and improve the economic efficiency. Under this background, State Postal Bureau decided to start the Interconnection-intercommunication engineering construction of postal service business system and the net transport system. Within the scope of the postal network service, they operate the beta-network-rization mode to deal with the record mails.
This article’s purpose is to realize the wholly functions of the control system that are signal recognization, receiving and sorting. According to the requirement of the sorting signal, it is going to need to design an automatic sorting system to realize the sorting system according to the brand, destination, or the the name of the receiver. It is also going to need to finish the choosing of components and design of the control system, to realize the control of the sorting, transporting devices and the sorting crossings, which include the hardware configuration, the developing of software and the design of frequency control of speed.
Key words: Mail Sorting Machine PLC frequency control of speed
