基于统计分析的节能优先电梯调度算法

Elevator scheduling algorithm for energy-saving based on statistical analysis

针对电梯满载率低、运行能耗大等问题,提出基于统计分析的节能优先电梯调度算法,利用统计结果分时段控制各电梯控制域、额外等待时间,实现局外电梯调度,并通过实验计算对比调度算法引入前后电梯运行能耗。实验表明,仅2台电梯1 h内节省能源26 474.4 J,优化比率达1.25%。

As the elevators are with low full-load rate and high energy consumption, an elevator scheduling algorithm for energy-saving based on statistical analysis is proposed. Control domain and extra waiting time of each elevator are controlled sub-period according to historical statistics,achieving outsider elevator scheduling. Experiments and calculation of energy consumption before and after using the algorithm proposed is also presented. Results show that just two elevators with proposed algorithm already save 26 474.4 J energy in one hour and the optimization ratio of energy is up to 1.25%.
