시뮬레이션을 활용한 스마트 LED 가로등 시스템의 인증기준 제안 및 검증

초록

This paper proposes certification standards for smart LED streetlight systems using simulation-based testing and verification. The lack of certification standards for smart LED streetlight systems has been identified as a critical issue, particularly concerning dimming control. This paper proposes three dimming control standards: the minimum time to initiate dimming, the duration of the dimming period, and the number of concurrent streetlights that can be controlled. For simulation modeling, Relux and analytical formulas are used to model streetlights and vehicles, respectively. The two models are integrated into the smart LED streetlight system models using Simio. The simulation experiments were conducted with two objectives: to present certification standards and to apply and verify real-world cases. Six hundred thirty scenarios were identified according to the installation environment and vehicle speed certification criteria suggestion. Then, the experimental results were applied to a specific road in the Republic of Korea. The certification criteria proposed in this study offer alternative approaches to operating the streetlight system more efficiently. The proposed simulation method proposed in this study can be applied to smart LED street lighting systems and various new products lacking certification standards.
