基于 PLC 的电梯群控系统

摘要

随着现代建筑技术的突飞猛进,高层和超高层建筑如雨后春笋。在
这些高层、大规模建筑中为满足需要一般都安装了多部电梯。在这种情
况下,有必要采用电梯群控系统对建筑物内的电梯群进行管理调度,协
调各电梯的运行,提高电梯的服务质量和运行效率。因此,研究和制造
智能化、高效的电梯群控系统,满足规模越来越庞大的现代建筑群的需
要,具有极其重要的现实意义,备受工业界的关注。
PLC( Programmable Logical Controller )全称可编程逻辑控制
器,自诞生起就始终处于工业自动化领域的主战场,为各类工业设备提
供非常可靠的控制手段。目前,PLC 与 DCS、工业 PC 并列成为现代工业
自动化的三大支柱。
基于上述背景,本文借鉴现有的电梯群控算法,通过实验验证和改
进,使用三菱公司的 PLC -Link 网构建电梯群控系统,实现了电梯
的合理调度。
本文构建的电梯群控系统为三电梯群控组,采用 Q 系列 PLC 作为上
位机进行群控调度;采用 FX2n 系列 PLC 负责单台电梯的运动控制;各
PLC -Link 网络进行通信;另外,使用触摸屏实

ELEVATOR GROUP CONTROL SYSTEM
BASED ON PLC

ABSTRACT

With the fast development of modern technology of architecture,
there appear more and more skyscrapers. Normally, several
elevators are built in each skyscraper to meet the needs of
passenger flow. To avoid wasting the resources of elevators, the
elevator group control systems are needed, which can manage and
coordinate the elevators in one building to improve the operation
performance and service quality. How to build intelligent and high
efficient elevator group control system is very important and
attracts much concern from elevator industry all over the world.
PLC(Programmable Logical Controller) is widely used in all
fields of the industry control and is noted for its high stability.
Today, new generation of PLC is more powerful, more flexible. Now
PLC has ranked one of the three major equipments for modern
industry control.
