摘要: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也得到了迅速发展,交流变频调速技术已经进入一个崭新的时代,其应用越来越广。而电梯作为现代高层建筑的垂直交通工具,与人们的生活紧密相关,随着人们对其要求的提高,电梯得到了快速发展,其拖动技术已经发展到了调频调压调速,其逻辑控制也由PLC代替原来的继电器控制。本文在已有的通用变频器的基础上,采用PLC对电梯进行控制,通过合理的选择和设计,提高了电梯的控制水平,并改善了电梯运行的舒适感,使电梯达到了较为理想的控制效果。
ABSTRACT:With the development of the economy, microelectronic technology, computertechnology and the automatic theory are developed rapidly, the AC variablefrequency technology has been in a new state. It's application is becoming moreand more widely. But the elevator as an important traffic in skyscraper,it also hasdeveloped quickly with the improving requirement of the people .It's draggingtechnology has developed from DC timing to AC variable frequency timing andit's logic control- relay control also has been replaced by PLC.    The article is based on the now-being general frequency converter, usingPLC to control the elevator, theis better through the reasonablemore ideal.reliability is improved and the feeling of comfortselection and design, so the effect of control is more ideal.
