摘 要
自动化立体库是一种集信息，存储管理于一体的高技术密集型机电一体化产品，是一种多层次存放货物的高架仓库系统。它是把计算机与信息管理和设备控制集合起来，能按控制指令要求自动完成货物存取的要求。
本文的设计思路是将整个立体库的区域虚拟的分为三个区，区域划分是基于物料属性信息之上的，本课题有三种物料，即高成品件、低黑件、低白件。根据物料属性信息分别将其放入相应的货位，以提高存取的工作效率。因PLC强大的控制功能，本控制系统的控制器采用PLC控制，堆垛机由两轴（X/Z）伺服定位轴机构组成，具有三自由度。堆垛机是自动化立体库中的重要设备，它能够在自动化立体库的货架间来回穿梭运行，将货物放入货架；或者相反取出货架上的货物。输送带由变频器控制，可以进行变频传输。采用光电传感器检测有无物料，变频传输物料，分析堆垛机的工作过程，并确定堆垛机的定位方案。通过计算机系统对PLC的运行监控，并对货架信息进行处理，解决了堆垛机存取货物路径的优化问题。最终由PLC对堆垛机系统进行控制。
人机界面，是系统和用户之间进行交互和信息交换的媒介，它实现信息的内部形式与人类可以接受形式之间的转换。人机界面可以对现场设备进行监控，及时采集系统信息，发现并处理故障，保证系统良好的运行，是自动化生产的必然发展方向。

ABSTRACT
Automated library is a collection of information, storage management in one of the high-tech-intensive mechanical and electrical integration products, is a multi-level storage of goods, overhead storage system. It is the computer and information management and control equipment together and follow the instructions to automatically control the access requirements of the goods.
This design idea is the area the entire three-dimensional virtual library is divided into three zones, zoning is based upon the material property information, the subject of three materials, namely high-finished parts, low black pieces, low white pieces. , Respectively, according to the material attribute information into the appropriate stock of its position, in order to improve access efficiency. PLC control for the powerful, the controller uses the control system PLC control, stacking machine consists of two axes (X / Z) axis servo positioning institutions, with three degrees of freedom. Automated stacking machine is an important equipment in the library, it can automated libra
