本文介绍一种电梯PLC控制系统。电梯是垂直方向的运输设备,是高层建筑中不可缺少的交通运输设备。它靠电力,拖动一个可以载人或物的轿厢,在建筑的井道内导轨上做垂直升降运动,在人们生活中起着举足轻重的作用。而控制电梯运行的PLC系统也要求越来越高,要求达到电梯运行的“稳、准、快”的运行目的。该系统主要由PLC、逻辑控制电路组成。其中包括交流异步电动机、继电器、接触器、行程开关、按钮、发光指示器和变频器组成为一体的控制系统。本机控制单元采用以三菱公司的可编程控制器PLC对机器进行全过程控制。-This text introduces the control system of a kind of elevator PLC.The elevator is perpendicular directional of the conveyance equipments be indispensable in the high building of transportation equipments.It depends electric power, dragging along to move a car that can carry person or thing and lead a track in the building of the well way up do perpendicularity to ascend and descend sport, there is prominent function in the people s life.And the control elevator circulate of the PLC system also has more and more high request, request to attain the movement purpose of "steady, quasi-, quick" of elevator movement.That system mainly from PLC, logic control the electric circuit constitute.Include an exchanges difference to tread electric motor among them, after the electric appliances, get in touch with a machine, route of travel switch and press button, give out light the indicator constitute and transducer for the control system of integral whole.The this machine control unit adoption car
