摘要
电梯作为现代高层建筑的垂直交通工具,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。文章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。
The elevator dragging technology has been developed from DC timing to AC variable frequency timing and the relay control also has been replaced by PLC. The article uses PLC to control the elevator based on general frequency converter. Its reliability and feeling comfort are improved.
