基于人员位置的室内智慧照明系统设计

A Design for Indoor Intelligent Lighting Systems Based on Location

摘要:

统计结果表明,现代人类滞留室内的时间超过生命周期的90%,由此产生的室内照明能耗已经成为建筑能耗的重要组成部分。针对当前室内照明系统能源浪费较大、误判率较高、控制方式复杂度较高等问题,设计了一种基于人员位置的室内智慧照明系统。通过动态优化复杂环境下电磁波传播模型,实现室内人员的精确定位,动态调整照明系统开/关时间,达到节能的目的。实验结果表明,系统相较于现有的声控照明系统,可以提高15%的室内照明能效,且误判率低于2%。

Abstract:

It is reported people spend more than 90% lifetime indoors, leading to the great increase of lighting energy consumption indoors. An intelligent and energy efficient lighting system is proposed in this paper to solve the problem of energy waste, high error rate and high complexity in the current lighting system depending on the occupants’ behavior. The electromagnetic wave propagation model is first optimized to predict the accurate position of occupants, followed by which the whole lighting system is switch on or off dynamically, targeting at the energy efficiency of the buildings. Experiment results show that the system, compared with the existing lighting system based on voice control, can improve the energy efficiency of lighting indoors at least by 15%, with a lower error rate below 2%.
