An adaptive control strategy based on usage analysis for office power management

In this paper, a control strategy is presented to coordinately control the switches of lamps and projectors in offices, especially for those offices with multiple meeting rooms. Firstly, it detects and collects the lamps and projects usage status through some devices, such as embedded sensors. Secondly, it analyzes the historical usage records of projectors and lamps and identifies several patterns for lamps and projector usage. Then, it clusters the control strategies for each pattern and determines the most popular used control strategy for each pattern. Finally, it updates and stores the most popular used strategy as optimal control strategy for execution. In order to verify its feasibility, efficiency and value, a prototype system and apparatus is proposed. And the experimental results prove it can help user to save power consumption and improve operation efficiency while using projectors.
