基于PLC和变频器的电梯控制系统设计

摘要

Designed the control system of elevator based on PLC and transducer, monitor the operation of the elevator while frequency intelligent control to the system, and it can save electricity and increase comfort. Installed a touch screen on the ground floor, which displaying the elevator position and which floor still need to stay next. On the other side the system realized the functions of real - time monitoring of steel rope tension, to prevent elevator overload.%设计了基于PLC和变频器的电梯控制系统,实行变频智能控制的同时对电梯的运行情况进行监控,有利于节省电能,增加舒适感.在一楼设置一触摸屏对目前电梯位置、乘客人数、还需停留几站进行显示.另外,系统对电梯提升钢丝绳的拉力进行检测,防止电梯超载.
