基于目标距离的VVVF电梯速度控制

VVVF elevator speed control based on desired distance

针对传统电梯速度控制技术中存在着的平层爬行、电梯运行效率不高的缺点,提出了基于目标距离的VVVF电梯的速度控制方式的基本原理,并采用嵌入式系统来实现其具体的控制过程。通过搭建试验平台进行实验测试。研究结果表明,采用这种新型的电梯速度控制技术可实现电梯无爬行平层,大大提高了电梯的运行效率。

Aiming at overcoming the shortages of traditional elevator speed control technique which are the relevelling crowl、the running inefficiency of elevator,the basic theory of VVVF elevator speed control system based on desired distance was presented and the specific control procedure was implemented by using embedded system.The results of the experiments indicate that using the new elevator speed control technique can achieve definite relevelling and raise elevator running efficiency.
