基于 s7-300PLC 五层电梯控制系统设计 摘 要 伴随城市建设不停进展，高层建筑不停增多，电梯在人们生活中占有着越来越主要地位。在高层建筑中，电梯更是不可缺乏垂直运输设备。伴随高层建筑飞速进展今日，电梯行业也随之进入了新进展时期,电梯控制技术已经进展到了调频调压调速，其逻辑控制也由 PLC 代替原来继电器控制，其许多功效是传统继电器控制系统无法实现。 本文针对我国电梯行业现实状况，将可编程序控制器 PLC 应用于五层电梯进行逻辑控制，经过合理选择和设计，不但提升了电梯可靠性、可维护性和灵活性，同时大大延长了电梯使用寿命，缩短了电梯开发周期，从而改进了电梯控制水平，提升了电梯运行舒适感，使电梯达成了较为理想控制效果。本文设计电梯与传统电梯相比，在运行过程中具备更为良好舒适感，在生活中能够节约电能，取得了良好经济效益和社会效益，达成了理想目标。该电梯控制系统具备指层、厅呼唤、选层选向、手动和自动等功效，具备集选控制特点。 在介绍电梯基本结构基础上，深化分析了电梯工作原理，阐述了 PLC 优点及特点，重点分析了电梯硬件设计和软件设计，讨论并提出了基于 PLC 电梯控制系统设计实现方案，最终对本论文讨论内容进行了总结与展望。 关键词：电梯；PLC；控制 ABSTRACT With the city construction's continuous development , the amount of high-rise buildings is increasing rapidly ， which makes the role that elevator played in people's daily life become more and more important. Especially in the high-rise building, th elevator is not a lack of vertical transportation equipment. With the rapid develop of high-rise buildings of today, the lift industry also has entered a new period of development, elevator control technology has been developed to the FM speed regulator, the logic control by the PLC to replace the original relay control, many its functions traditional relay control system can not be achieved. The design for the status of China's elevator industry will be a programmable logic controller (PLC) used for four-storey elevator control logic, through the rati selectio...
