设计简介
基于PLC的智能仓库控制系统的设计
摘 要
随着国民经济的飞速发展,智能仓库必然会在各行各业中得到越来越广泛的应用。智能仓库系统是现代物流系统的一个重要组成部分,广泛应用于各行各业中。目前,它已经成为企业生产和管理信息化的标志之一。
该系统采用PLC控制,通过PLC输出的脉冲信号来控制步进电机的运行,两者之间通过步进电机驱动器连接,此外还用到一些传感器,如微动开关和反射式传感器。
此次设计的效果可以改变参数输入,通过模拟生产情况及波动对系统造成的冲击,从而避免了在理想化状态下系统设计所无法预料的各种因素,对系统的堵塞有着形象和直观的解决方案。
总之,智能仓库因其较小的占地面较佳空间利用率,应用正逐渐普及。为满足现代化生产和流通的需要,就必须采取以计算机控制主要手段的智能仓库。

DESIGN OF INTELLIGENT WAREHOUS SYSTEM BASED ON PLC CONTROLLED
ABSTRACT
Along with the rapid development of national economy, Intelligent warehouse in all walks of life will get more and more widely. Automatic warehouse system of modern logistics system is an important part of, is widely used in industries. At present, it has become the enterprise production and management, one of the symbols of informatization.
The system adopts PLC controlled by PLC, the output pulse signals to control the operation of the step-motor between through the stepping motor drive connections, also used as some sensors, micro switch and reflex sensor.
We can alse see the place where the block and bottle-neck have taken place and state how they develop, reflecting by the system of simulation. By changing the input of the parameters and simulating the process of production and the impulsion of system arosed by flactuation, we can avoid various unforeseen factors of system design in the state of idealization, have visual and intuitionistic solving way for the block of the system.
In conclusion, The application of automatic warehouse with less floor space and better space utilization ratio has been popularizing gradually. To meet the requirement of the modern production and negotiation, it should use the warehouse with the computer control technology.
KEY WORDS: Intelligent warehouse, PLC, Stepping motor, Sensors,
