摘要
为了克服传统电梯速度控制方式的缺点,提高电梯运行效率,基于现有VVVF电梯速度控制方式,提出了以绝对剩余距离为原则的电梯速度控制方法,介绍了其优点和关键技术,并介绍了使用嵌入式系统实现以绝对剩余距离控制电梯的运行速度的实验室方法。仿真试验表明,该方法可以使电梯平层停车时直接停靠,大大提高了电梯的运行效率。
In order to overcome the shortage of traditional elevator speed control methods, increase the nnming efficiency of elevators, the method of elevator speed controlling based on absolute surplus distance is presented, and the advantages and key technologies are introduced. The experimental result indicates the method can improve the efficiency of elevators.
