1、 中文题目：基于 PLC 的双速六层电梯控制系统设 计 外文题目：The control system design of two speed six floor elevator basic on PLC I 摘要 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。传统的电梯控制系统采用的是继电器逻辑控制电路， 这种控制易出故障，维护不便，运行寿命短，占地空间大，正逐步被淘汰。 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

2、（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。 关键词：PLC；电梯；逻辑控制；程序设计 II Abstract Along with the urban construction development unceasing, the high rise building increases unceasingly too. Elevator as a vertic

3、al transport operation in the high rise building, it was closely related to the peoples daily life. The traditional elevator control system uses logic of the relay to control circuit, this kind of controls easily to be crash, maintains inconveniently, the movement life is short, and that occupying a

4、 large area of space, it being eliminated gradually. For raising the credibility of the automatic control system and the work efficiency of the equipments, design a set of take PLC as the core controller of the elevator auto control system, using to replace former more complicated of after electric

5、appliances-the contact machine control. The core part(control part) of the system used a Japanese Mitsubishi company to produce of the FX2N - 80 MR type PLC is the software procedure control in the core because of what to control the part adoption, thus Be promising the elevator circulates normally

6、under the circumstance ofwith this request, raised elevator to break down check and the convenience and easy for maintain consumedly, still overcame to move an operation some artificial interference factors bring in the meantime, obtain the good economic performance and social performance.
