Abstract

Following ISO 20471, in this study, first, two sets of safety clothes and safety vests were made by designing and attaching animal and bird patterns preferred by children to retroreflective films and black fabrics on those fluorescent fabrics and retroreflective materials prescribed by international standards. Second, by mounting a smart photonic device on the safety clothing so that the body can be recognized from a distance even without an ambient light source at night, children can emit three types of light depending on the situation with just one-touch of the button. From a result of comparison with visibility a day and night by dressing a mannequin in the made smart safety clothing, the difference in visibility was evident at night, it was confirmed that we can see the figure of a person even at a distance of approximately 70 m. Therefore, it is expected to contribute to the prevention of traffic and other accidents on the road, as the drivers driving at night or in bad weather can recognize a person from a distance. Third, in case of the energy is exhausted and cannot maintain the stability of the light-emitting function of the optical faber, we can use energy harvesting device, and the light-emitting time will be extended. As a result it comes up to emit light stably for a long time. And this prove that smart photonic safety clothing can also be used for night workers. Therefore, optical fiber safety clothing is expected to be highly wearable not only in real life but also in dark industrial sites due to stable charging by applying the energy harvesting provided by solar cells.

본 연구에서는 첫째, 국제표준에서 규정한 형광직물과 재귀반사 소재에, 아동들이 선호하는 동물의 문양을 재귀반사 필름과 검정색 직물로 디자인하여 부착한, 2벌의 안전의복과 안전조끼를 제작하였다. 둘째, 야간에 주변광원이 없어도 원거리에서 생체를 인지할 수 있도록 안전의복에 스마트 포토닉 디바이스를 장착함으로써, 어린이들이 어두운 때 버튼 원터치만으로 상황에 따라 3가지 발광이 가능하도록 구현하였다. 제작한 스마트 안전의복을 마네킹에 착용시켜 주야간의 시인성을 비교한 결과, 시인성의 차이가 야간에 확연히 나타났는데, 기존의 안전의복 착용 시에는 주변광원 없이는 착용자가 표출되지 않은 반면, 스마트 안전의복 착용 시는 약 70m의 원거리에서도 표출됨을 확인하였다. 따라서 야간이나 기상악화 시에 주행하는 운전자가 원거리에서 생체를 인지할 수 있어 교통사고나 도로상의 안전사고 예방에 기여할 것으로 기대된다. 셋째, 광섬유의 발광기능 안정성 유지와 발광시간의 연장을 위하여 에너지 소진 시 태양전지로 수확한 전기에너지를 사용함으로써, 장시간 안정되게 광섬유 발광이 가능하여 시인성의 안정성을 확인할 수 있었다. 이로써 스마트 포토닉 안전의복은 야간 작업자용으로도 활용 가능함이 증명되었다. 그러므로 광섬유 안전의복은 태양전지에 의한 에너지 하베스팅 적용으로 안정적인 충전에 의해 실생활뿐만 아니라 어두운 산업현장에서도 착용 가능성이 높을 것으로 기대된다.
