摘要
电梯作为高层建筑物内的垂直交通工具，与人们的工作和生活日益密切，由于各种原因，电梯会出现一些不安全的运行状态，其中电梯超速运行是电梯一种非常不安全的运行状态．分析了在不同运行状态下电梯超速的可能性，介绍了一种检测电梯超速的方法，采用ＰＬＣ对电梯进行限速控制，并编制了相应软件．
The elevator, as a vertical transportation of the high construction, is closely related to people's work and life. For a variety of reasons, the elevator occurs probably some unsafe states, overspeedoperation of elevator is a much unsafe state. This paper analyses overspeed probability of elevator in the different operating state, presents a method of detecting overspeed of elevator, PLC is employed to accomplish restricted sped control of elevator, and develops corresponding software.
