基于PLC的自动化立体仓库设计

摘 要

随着国民经济的飞速发展,自动化立体仓库会在各行各业中得到越来越广泛的应用。自动化立体仓库是现代物流系统的重要组成部分,是一种多层存放货物的高架仓库系统,由自动控制、管理系统、高位货架、巷道堆垛机、自动入库、自动出库、计算机管理控制系统以及其他辅助设备组成。本仓库模型控制系统是根据自动化立体仓库运行的基本原理而设计的。在整个控制系统中以三菱FX2N系列PLC作为核心控制元件,专用键盘作为人机接口部件,控制步进电机来驱动一个有三自由度的仓库模型在高强度导轨上做三维运动。以步进电机每转输出的脉冲数为基础,通过键盘对每个仓位予以地址编码,通过PLC对命令键盘进行扫描并得到相应的仓位号,当PLC接收到来自键盘的输入命令后,便输出对应仓位的脉冲数,经过驱动器驱动步进电机按设定的方向转动一定的角度,进而控制传动部件丝杠旋转进行准确的定位,以完成货物的存取功能。另外,为了保证整个控制系统运行的稳定性和可靠性,我们还采用了限位开关对其进行限位保护。 本文首先对该课题的可行性及课题实现的现实意义和价值进行了介绍;其次对该系统的硬件组成、结构、原理进行了阐述和分析;再次对本控制系统的核心软件进行了编写,论文中既有梯形图又有相应的语句表;最后对设计本课题所学到的知识和结论进行归纳和总结,并对本论文有待完善的地方进行扼要的说明。

Based on PLC automatic stereoscopic warehouse design

Abstract

With the rapid development of national economy, the automation stereoscopic warehouse will get more and more extensive application in all trades and professions. The automated warehouse is an important part of modern logistics system, elevated warehouse system for a multi-layer storage of goods, which consists of automatic control and management system, high shelves, stacking machine, automatic storage, automatic warehouse, computer control system and other auxiliary equipment. The warehouse model of the control system is designed according to the basic principle of automated warehouse operation. In the whole control system in order to Mitsubishi FX2N series PLC as the core control element, a special keyboard as the man-machine interface unit, control the stepper motor to drive a warehouse model of three degrees of freedom movement in three dimensional high strength rail. This paper first introduces the feasibility and the subject of the implementation of practical significance and value; secondly, the system hardware composition, structure, principle are described and analyzed; the core of the control system again -- software has been written, the paper is a ladder diagram and the corresponding statement at the end of the table; the subject of the design knowledge and conclusions are summarized, and the perfect place to be making a brief explanation.
