마이크로웨이브 센서와 조도 센서를 활용한 스마트LED조명제어

Abstract

High-rise buildings in Korea have been increasing rapidly. So electrical energy consumption is increasing in the building. Especially lighting system is more 20% percent of total power generation. In the past, Traditional lighting system was operated to check presence of people by PIR sensor or full output. Pyroelectric infrared sensor don't have reliability due to malfunction. So, improve the operation of lighting system uses network communications and new sensor. Utilizing network communications and variety of sensors for lighting control technology is called a smart lighting system. This paper, To implement a smart lighting system first, PRI should be replaced with a microwave sensor. Second, the manufacture of LED lighting appliance is microwave sensor, illumination sensor ,and microprocessor. At last, LED lighting control system is applied by an Fuzzy algorithm rule. Control of LED lighting appliance is judged fuzzy control algorithm depending on the presence of people by microwave sensor and brightness of ambient. Finally, Power consumption of smart LED fuzzy lighting system compared with traditional lighting system and recognizing base system of resident.
