Towards Demand-Responsive Intelligent Lighting With Wireless Sensing and Actuation
نویسندگان
چکیده
Commercial daylighting systems can generate significant savings in electricity consumption, yet they are poorly received in the commercial or office building sector. Barriers inhibiting widespread adoption of these daylighting systems include occupant dissatisfaction, high cost (especially in the case of retrofits), and difficulty estimating target illuminances. In order to overcome some of these barriers, an intelligent control framework is developed, and a new MEMS-based (micro-electrical mechanical systems) wireless sensing and actuating technology called ‘Smart Dust motes’ is explored. Through intelligent control, conflicting occupant preferences and perceptions can be balanced, demandresponsiveness can be implemented, and sensed values of illuminance can be validated and fused. Validation refers to the process of determining the fidelity of sensed information. Validated readings from physically or functionally redundant sensors are aggregated with fusion algorithms. Smart Dust motes afford sensing directly at the worksurface, as well as individual control of ballasts sharing a common switch. In this paper a framework for intelligent daylighting control with Smart Dust motes is presented. Specifically, calibration of mote sensors, development of the intelligent control model, and fusion and validation algorithm assessment are detailed.
