Abstract:	本論文著重於建立出一套燈具調變控制系統，以利於公共空間的節能省電，在搭配上冷氣方向調變的系統更將節能的效果更加提升。一般常見的攝影機直接插入USB接頭便可使用在個人電腦上，配合人機介面將接收到的影像做處理，包含HSL色彩轉換、灰階色彩轉換、位置追蹤處理等等，取得到有利於控制燈、馬達、冷氣、風扇的資訊，最後傳送出資料改變各個周邊硬體的狀況，使的整體公共空間的的無論是光源、溫度、二氧化碳濃度都能達到人體最舒適的階段，這樣的系統不但節能，並且提升了一般生活品質。在燈具亮度的調變上，使用了RS-232串列通訊作為電腦以及微控制器8051的溝通橋樑，以亮度為輸入，透過模糊控制法做出運算得到調變亮度數值，並且輸出到8051上做出PWM(脈衝寬度調變)的調整，達到目標亮度。 This thesis focuses on setting up a light modulation system, which saves energy in public places. The energy-saving process would be improved by combining with the air conditioning wind modulation system. Generally, the camera can be directly plugged in to one’s personal computers by USB connector, so it can be used easily. We adjust the images by using interface captures like HSL conversion, gray conversion and location tracking. Then we get the best control data to the light, motor, air condition and fan. Finally, computers will send out data to surrounding hardware. The hardware change the light, temperature and carbon dioxide concentration which makes the environment more comfortable in public place. Such system not only saves energy but also improves the quality of our lives. In the lamp brightness modulation, we use RS-232 serial communication to connect the computer with the microcontroller 8051 we used. The brightness would be the input, then we use basis fuzzy control rule to calculate how bright the environment actually need. After that we use microcontroller 8051 to gather the data and then modify the PWM output to get to the brightness we need.
