电梯控制系统论文 交流变频变压调速电梯PLC控制系统.doc

摘 要 随着科学技术的发展，电梯行业出现了翻天复地的变化：电梯企业的生产条件、人素质、管理水平有了极大的改善与提高我国电梯已形成了设计制造、安装调试、维修保养一条龙服务的一个完整的行业老的直流电梯已被淘汰，交流双速梯、ACVV交流调速梯逐渐被VVVF交流变频变压调速电梯所取代，控制系统已在大量采用PLC和微电脑控制技术，VVVF交流变频变压调速电梯With the development of science and technology, the elevator industry appeared to change: a complex enterprise production conditions, the elevator humanistic quality management level, the great improvement and improve. China elevator has formed the design, manufacture, installation, commissioning, maintenance of enterprise-stop services of a complete industry. The company also has a great improvement in elevator design, process changes and update production more new elevator. Elevator mechanical system mainly divided into two most with control system, with the automatic control theory and microelectronics technology development, the elevator and control means drag has changed very greatly, the old dc elevator has been eliminated, communication, ACVV exchange double speed stepless frequency is gradually VVVF ladder replaced with variable pressure regulation, control system, elevator has lots of PLC and microcomputer control technology, and PLC control system, high reliability due to the convenient usage and maintenance, strong anti-interference, design and commissioning period is shorter, etc, has been used in the elevator control system in most control mode. Key words: VVVF ac frequency conversion variable speed elevator、PLC control system 目 录 摘要........................................................... 4 第一章 电梯的概述............................................ 5 1.1电梯的发展........................................................ 6 1.2电梯的分类........................................................ 7 1.2.1按用途分类...................................................... 8 1.2.2按驱动方式分类.................................................. 8 1.2.3按速度分类...................................................... 8 1.2.4按电梯有无司机分类.............................................. 9 1.2.5按操纵控制方式分类.................
