随着城市建设的不断发展，高层建筑不断增多。电梯作为高层建筑中垂直运行的交通工具已与人们的日常生活密不可分。目前电梯控制系统主要有三种控制方式：继电路控制系统(“早期安装的电梯多位继电器控制系统)、PLC控制系统、微机控制系统。继电器控制系统由于故障率高、可靠性差、控制方式不灵活以及消耗功率大等缺点，目前已逐渐被淘汰。微机控制系统虽在智能控制方面有较强的功能，但也存在抗扰性差，系统设计复杂，一般维修人员难以掌握其维修技术等缺陷。而PLC 控制系统由于运行可靠性高，使用维修方便，抗干扰性强,设计和调试周期较短等优点，倍受人们重视等优点，已成为目前在电梯控制系统中使用最多的控制方式。亘坨瞰钞囹醯等监量睑恽测融
为了提高自动控制系统的可靠性和设备的工作效率，设计了一套以PLC为核心控制器的电梯自动控制系统，用来取代以往的较复杂的继电器—接触器控制。系统的核心部分（控制部分）使用了日本三菱公司生产的FX2N-80MR型PLC，因为在核心控制部分采用的是软件程序控制，从而在保证电梯正常运行这个要求的情况下，大大的提高了电梯故障检查与维修的方便性和容易性，同时还克服了手动操作所带来的一些人为干扰因素，取得了良好的经济效益和社会效益。苻策酶聋欣绰翕芈扭清鸳湾畸

Abstract檠躇旮所庵酃嫡化半劳旯喏沧
With the continuous development of city construction, high-rise building increasing all the time. The lift, as the high-rise buildings in the vertical of transportation has run with People's Daily lives are inseparable. At present the elevator control system mainly have three control mode: after circuit control system (" early installation of elevator more relay control system, PLC control system, the microcomputer control system. Relay control system due to failure rate high, poor reliability, control pattern and not flexible and disadvantages such as big power consumption, currently has gradually been eliminated. Though the microcomputer control system in intelligent control has the strong function, but also has the perturbation resistance is poor, system design complex, generally maintenance personnel are difficult to grasp its maintenance technology wait for blemish. And PLC control system due to run high reliability, convenient operation and maintenance, anti-jamming is strong, the design and debug cycles shorter etc, and has attracted much attention etc, and has become a problem which in the elevator control system in use most control mode.
