摘要
介绍PLC技术在电梯领域的应用;分析和处理了随机信号的逻辑关系;提出了双匀速电梯的PLC编程方法;实现了当目标位置离当前位置较近时的中速运行和较远时的高速运行,即双匀速运行,从而提高了电梯的运行效率。
This paper introduces the application of PLC in the elevator field,analyses,processes the logic relations of random signal and puts forth a method of the two-speed elevator PLC programming.When the elevator goes away from its current location,it runs at medium speed,and when it goes faraway it runs at high speed,this is called double constant-speed,which can enhance the operating efficiency of the elevator.
