    商城客用六层电梯PLC控制系统设计
    摘 要:科技的不断发展带动了城市现代化的进程,从工业时代逐渐步入科技时代,人口集中土地资源越来越昂贵,导致高层建筑越来越普遍。高层建筑载人搭物就不可避免的需要使用电梯。如何保障电梯安全可靠而且节能环保是电梯改造的主要问题。为了避免类似问题,达到工作效率高并且安全可靠的目的,本文设计PLC作为控制器自动控制系统,弥补继电器接触器的不足。系统控制部采用FX2N-80型PLC,用软件程序来监控运行过程,可以在正常运行的时候注意监控相关数据,提前发现问题,保证维修时间短效率高,提高电梯的性能和可靠度。

     Mall customer design PLC control program with six elevators
     Abstract:The continuous development of science and technology led to the modernization of the city, from the industrial age has gradually entered the era of science and technology, population concentration of land resources are becoming more and more expensive, resulting in high-rise building is becoming more and more common. A substance used in high-rise building manned elevator will inevitably need to. How to ensure the elevator safety and energy saving and environmental protection is a major problem in elevator renovation.For raising the credibility of the automatic control system and the work efficiency of the equipments, design a set of take PLC as the core controller of the elevator auto control system, using to replace fermer more complicated of after electric appliances-the contact machine control. The core part(control part) of the system used a Japanese Mitsubishi company to produce of the FX2N - 80 type PLC is the software procedure control in the core because of what to control the part adoption, thus Be promising the elevator circulates normally under the circumstance of[with] this request, raised elevator to break down check and the convenience and easy for maintain consumedly, still overcame to move an operation some artificial interference factors bring in the meantime, obtain the good results

    本课题主要是研究民用电梯的plc控制,包括plc如何运行,当然需要解决的问题也很多,包括你需要了解电梯的运行方式,根据基本技术参数,构建电梯的框架,设计流程,选择合适的有关硬件,研究步骤首先要找一些有关的参考文献,模拟各个结构的方案,从许多方按中选出更合理的方案,然后将电梯的硬件图,I\0表流程图以及梯形图弄出来,然后在电脑上模拟,调试。
