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。
根据选择的轿厢楼层位置检测方法，要求可编程控制器必须具有高数计数器。又因为电梯是双向运行的，所以PLC还须具有可逆计数器。综合考虑后，本设计选择了日本三菱公司生产的FX系列机。FX系列机具有体积小，功能较强，价格便宜，使用灵活、方便等优点。本设计按四层的电梯考虑。

ABSTRACT
With the development of the economy, microelectronic technology, computer
technology and the automatic theory are developed rapidly, the AC variable
frequency technology has been in a new state. It's application is becoming more
and more widely. But the elevator as an important traffic in skyscraper，it also has
developed quickly with the improving requirement of the people .It's dragging
technology has developed from DC timing to AC variable frequency timing and
it's logic control- relay control also has been replaced by PLC.
The article is based on the now-being general frequency converter, using
PLC to control the elevator, the reliability is improved and the feeling of comfort
is better through the reasonable selection and design, so the effect of control is
more ideal.
