[국내논문]기상 모니터링과 색 온도 제어 시스템을 지원하는 무선 LED 가로등 플랫폼 설계 및 구현 Wireless LED Streetlight Platform with Weather Monitoring and Color Temperature Control System원문보기
본 논문에서는 기상 모니터링과 색 온도 제어 기능을 갖춘 LED 가로등 플랫폼의 설계와 구현을 제안한다. 이전 연구에서는 가로등 시스템의 에너지 효율이나 데이터 관리에 중점을 두었으나 조명 성능에 대한 연구는 이루어지지 않았다. 특히 안개나 연무와 같은 기상현상은 운전자와 보행자의 시야를 방해하기도 한다. 이러한 문제를 해결하기 위해 서로 다른 색온도를 가지는 두 개의 LED 램프를 사용하는 것을 제안한다. 이 램프는 거리의 조건에 따라 서로 전환이 가능하다. 또한 우리는 시스템 내 각 장치들 간의 통신 체계 설계한다. 더 나아가 실험결과를 통해 이 제안된 LED 가로등 플랫폼이 잘 수행되고 데이터가 웹 사이트에 제대로 표시될 수 있음을 보여준다.

In this paper, we propose the design of LED Streetlight Platform with capabilities of weather monitoring and color temperature control. Several previous works are focused on the energy efficiency or data management of streetlight system, but no work has been done on the lighting performance, especially when natural phenomenon such as fog or haze appears on the street and obstructs the visibility of drivers and pedestrians. To solve such issue, we propose the use of two LED lamps with different correlated color temperature, which will be activated interchangeably according to the condition on the street. We also present the design of communication scheme between each devices in the system. Moreover, our experimental results show the LED Streetlight Platform can perform well and the data can be displayed properly at the website.

문제 정의
Several streetlight implementation has been done to tackle issues such as energy usage and data management, but only few discuss about the lighting performance. This paper has proposed an LED Streetlight Platform to provide good visibility by road illumination in clear weather and in fog or haze situation. We present and explain in detail about the communication protocol and the hardware design of the platform.
가설 설정
1) Custom design of LED Streetlight Platform is proposed.
제안 방법
12. In this experiment we use XTU configuration and test utility software to measure the effective distance between two consecutive ZigBee devices. Accordingly, the test result shows all packets are successfully transmitted between the transmitter and receiver devices.
[6] The design of remote streetlight monitoring using WSNs is considered in.[7]In this work, central control unit is used to monitor streetlight system, display topology and location maps, and send control messages to remote units, thereby gathering information of each streetlight. The sensor node in this work is used to turn the streetlight on and off, and also for dimming functionality according to the received messages from the remote unit.
대상 데이터
The LED switching module consists of three main components: bipolar transistor 2N2222, optocoupler FOD817, and switch-mode power supply (SMPS) metal-oxide-semiconductor field-effect transistor (MOSFET) IRFS31N20, as shown in Fig. 10. The switching module is designed as active-low module.
The third sensor module is PM1001, a dust sensor module that can detects particles less than or equal to 10 μm in diameter (PM10).
