基于西门子PLC的双轴立体仓库PLC控制系统设计
摘要
企业的稳定发展,也迅速的经济全球化,我国的行业也发生了变化,一方面,高科技越来越广泛的加工技术,加工效率大大提高。同时原有的物流和仓储系统不能满足新形势的要求,建立一个集物流、信息流和资本流动在一套自动物流管理中心,以降低企业物流成本,提高企业综合效益已成为目前亟待解决的问题。自动化立体仓库的出现, 实现了仓库功能从单纯保管型向综合流通型的转变， 而且自动化立体仓库是现代物流与仓储系统的重要组成部分，具有货物存取效率高和自动化程度高、很强的出入库能力等优点。而PLC功能强大，可靠性高，抗干扰能力强，维修方便，易于实现机电一体化。完全满足立体仓库工作环境和控制系统的要求。本设计采用西门子S7-200系列的PLC作为控制核心，实现一个12仓位的立体仓库的入库出库功能，立体仓库主体有底盘，两层八仓位仓库，运动机械及电气控制等组成。S7-200型可编程控制器作为控制核心，采集输入端口信号后完成各种逻辑控制和数据的运算，然后通过输出端口完成电机的运动和各种信号的实现。

The double-shaft stereoscopic warehouse PLC control system based on Siemens PLC design
TOPIC
With the steady development of the enterprise, also rapid pace of economic globalization, our country's industry also has changed, on the one hand, the processing technology of the high-tech more and more widely, machining efficiency has been greatly improved. At the same time the original logistics and warehousing system can not meet the requirements of new situation, to establish a set of logistics, information flow and capital flow at a suit of automatic logistics management center, to reduce enterprise logistics cost, improve enterprise comprehensive benefits has become a problem to be solved at present. Automated stereoscopic warehouse, to realize the function of the warehouse from the simple to comprehensive flow-through storage type, and automated stereoscopic warehouse is an important part of modern logistics and warehousing system, access to goods with high efficiency and high automation degree, strong ability for ins and outs of advantages. The PLC powerful functions, high reliability, strong anti-jamming capability, easy maintenance, easy to realize the mechanical and electrical integration. Fully meet the requirements of stereoscopic warehouse work environment and control system. This design adopts the Siemens S7-200 series PLC as control core, to implement a 12positions of stereoscopic warehouse inbound outbound function, subjects of stereoscopic warehouse chassis, two layers of eight positions in the warehouse, mechanical and electrical control, etc. S7-200 PLC as control core, after the acquisition signal input port complete variety of logic control and data calculation, and then through the output port complete motor movement and the implementation of various kinds of signals.
