| Abstract |
This paper proposes a novel design of auto light control system with high efficiency using RS-485 to save lighting energy in new and existing buildings. The proposed system consists of ALSU(Auto Light Sensor Unit) which is connected with RS-485 to control lighting appliances, ALS(Auto Light Unit), and Hi-FACS which is a monitoring system using communication interface. Lighting appliances are automatically controlled by ALSU which detects moving objects. The total system is designed to be controlled by either manual or auto mode by using the ALS. In addition, the monitoring system receives the information on the state of the lighting appliances from ALSU and ALS to control the proposed system. We compared the proposed system with the conventional one in functionality and energy saving point of view. Through some experimental results, the proposed system shows better performance in various circumstances. |
