基于PLC的现代物流技术

The Modern Logistics Technology Based on PLC

自动化立体仓库作为现代物流系统中的一个重要组成部分,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成起来,能按照控制指令要求自动完成货物的存取作业,并能对库存的货物进行自动管理,达到仓储技术的全面自动化。因此,自动化立体仓库也是企业管理现代化的重要手段之一。可编程控制器(PLC)作为自动控制的三大技术支柱(PLC、机器人、CAD/CAM)之一,成为大多数自动化系统的设备基础。用PLC控制的自动化立体仓库达到仓储技术的全面自动化。

Automated warehouse, as an important part of modem material handling system, is a kind of multi-layers warehousing system. It integrates computers, information management system and control devices, which can conduct storing and retrieving under the order of control instruct and management goods automatically. Thus, such an automated warehousing system is an important way of realizing the modernization of enterprise management, As one of supporting techniques, PLC is a fundamental device in most automation systems. The automated warehouse controlled by PLC is a full automation in warehousing system, This paper designs the system based on PLC.
