碩士 === 中華大學 === 電機工程學系 === 104 === Intelligent lighting control based on digital address lighting interface (DALI) has been studied in the thesis. Polynomial with various orders has been utilized to describing the relationship between the power level of lamp and the lux sensor. The constant coefficient is corresponding the background noise which will be varied with the environment changing. Especially, the coefficient corresponding to the first order has been demonstrated to be the most consistent, so it can be used to identify the malfunction of lamp, such as aging or breakdown problem. The useful information can let the maintenance department to keep the track of lighting system well. Multi-Lamp and Single-Sensor (MLSS) and Multi-Lamp and Multi-Sensor (MLMS) models have been built with the estimated polynomial. Its slope is adopted to design Single Adjust Control (SAC) and Uniform Power Control (UPC). Its concavity can improve the integer programming power level problem. Threshold for lamp staring to affect the lux sensor is taken in to account in the thesis. Both control methods can smartly achieve the targeting setting very well.
