电梯控制策略的研究.pdf

中文摘要

随着科学技术和社会经济的发展，高层建筑已成为现代城市的标志。电梯作
为垂直运输工具，承担着大量的人流和物流的输送，其作用在建筑物中至关重要。
因此对于电梯的研究也显得更加有意义。与此同时，人们对电梯的性能要求越来
越高，比如可靠性、操纵方便、舒适性、低能耗等。因此也得到了快速发展，其
逻辑控制由 PLC 代替原来的继电器控制，采用 PLC 对电梯进行控制，通过合理的
选择和设计，能够有效的提高电梯的控制水平，极大地改善电梯运行的舒适感，
使电梯的控制达到了比较理想的控制效果。
本文首先阐述了电梯的控制原理，介绍了电梯控制系统的硬件设计，并通过
PLC 编制控制程序，实现对电梯控制的程序设计。其次研究了电梯并联调度算法，
通过对传统并联调度算法的介绍并指出其不足之处，提出了最快响应并联调度算
法，并通过 PLC 编程将此算法实现，应用到电梯并联控制系统中。在此基础上，
研究了电梯群控算法，运用模糊控制技术进行交通模式的识别，并利用专家经验
得到电梯在各个交通模式下的权系数，采用多目标优化电梯群控性能评价函数，
为电梯群控调度算法的研究提供一种新思路。
最后，本文在基于电梯控制系统的设计基础上，进行了人机界面（HMI）的
研究和设计。通过触摸屏可以监控主、副梯的群组运行状态、故障报警状态、轿
厢门状态、电梯运行方向、电梯轿厢位置、电梯的优先调度、电梯响应的外呼召
唤等。并通过离线模拟和在线模拟，将电梯的运行状态进行离线和在线模拟，使
群控系统正确、高效的运行。

Research of Elevator Control Strategy

Abstract

With the development of science, technology and socio-economic, high-rise
buildings have become the hallmark of modern cities. As vertical lift equipment, a lot of
people bear the transportation and logistics, its role in building essential. At the same
time, it has to lift the performance requirements are also increasing, such as reliability,
easy to operate, comfortable nature, and low power consumption and so on. With the
fast development of elevator, its logic control-relay control also has been replaced by
PLC. The reliability and the feeling of comfort are improved through the reasonable
selection and design by using PLC to control the elevator, which makes the effect of
control more ideal.
In this paper, the drive and control principle of elevator is introduced in the first
place. The design of elevator system is proposed in the paper by writing PLC program
for implementing the control of elevator,
