文档介绍：PLC控制电梯
摘要
在现代社会及经济活动中,电梯已成为城市物质文明的标志。电梯性能的好坏对人们生活的影响越来越显著,因此必须努力提高电梯系统的性能,保证电梯的运行既高效节能又安全可靠。随着我国经济的高速发展,微电子技术、计算机技术和自动控制技术得到了快速发展,交流变频调速技术已进入一个崭新的时代,其应用越来越广。新技术的产生发展同时也促进了电梯行业的快速发展。现在电梯的拖动技术已经发展到了变压变频调速,其逻辑控制也由PLC代替原来的继电器控制。
本文采用PLC和变频器实现电梯常规控制的基础上,通过对变频器和PLC芯片的合理选择和设计大大提高了电梯的控制水平,使电梯达到了较为理想的控制和运行效果。

ABSTRACT
In the modern social and economic activities, the elevator has e a symbol of urban material performance good or bad influence on people's lives more and more significant, so must try to improve the performance of the elevator system,  to ensure energy-efficient operation of the lift both safe and reliable. Along with our country economy, the rapid development of microelectronics technology, computer technology and automatic control technology obtained fast development, VVVF technology has entered a new era, its application more widely. The generation of new technology development and promote the rapid development of the elevator industry. Now drag the elevator technology has developed to the VVVF, which is also controlled by the PLC logic to replace the original relay control.
In this paper, to achieve lift conventional PLC and inverter control, based on the frequency converter and the PLC chip through the rational selection and design greatly improves the level of control of the elevator, the elevator reached the ideal control and operating results.
