摘要
随着现代高楼大厦的林立,电梯变得必不可少。而电梯又是电气与机械结合于一体的大型机电设备,把变频器、"PLC"可编程逻辑控制器等运用到电梯上,并替代掉传统意义上的继电器——机械调速以及接触器控制装置,能够极大地降低控制系统的接线与零部件,不仅提升了电梯运行时的可靠性,还大大地降低了电梯故障的发生,方便人们对电梯进行维修与维护,提升大家对乘坐电梯的时候的舒适感。本文结合多年的实践工作,阐述了电梯工作的基本原理,分析了电梯控制系统的硬件设计以及控制系统软件的设计,希望能够为设计出成本低,能够广泛运用到低层多种用途的电梯上提供一些有价值的参考。
With modern high-rise buildings everywhere, elevator becomes essential.The electrical and mechanical elevator is bound to one of the major mechanical and electrical equipment.The inverter, ＂PLC＂ programmable logic controllers to use the elevator,and replace the relay off in the traditional sense - mechanical speed and exposure control device.It can greatly reduce the control system wiring and components.Not only to enhance the reliability of the elevator runtime,but also greatly reduces the incidence of failure the elevator.Convenient for people on the elevator repair and maintenance,we enhance the comfort of the ride when the elevator.This article combined with years of practical work, describes the basic principles of the elevator work, analyzes the elevator control system hardware design and software design of the control system, hope to design a low cost, can be widely applied to lower the elevator to provide a variety of purposes some valuable reference.
