요약
이 연구는 옥내소화전설비에 자동화점추적 기능을 부가하여 화재 발생위치에 따라 방수노즐이 이동하여 유효하게 방수하는지를 방수중심 지향여부, 방수범위 유지여부, 방수형태의 일관성 유지여부로 구분하여 실험하고 결과를 고찰하였다. 첫째, 방수중심 실험결과는 최초 화원의 중심을 찾는 정확도는 시스템 설계에 있어서 유효한 결과를 도출하게 됨을 확인하였다. 둘째, 방수범위 실험결과 방수최대반경의 물 분사를 하는 경우 방수범위의 오차는 허용공차 범위 내에 들어가는 것으로 확인되었다. 마지막으로 방수형태 실험결과 형태의 변화 없이 정상동작하여 설정블록에 대하여 설계상태가 이상 없음을 확인하였다.
Abstract
To determine if water-jet nozzle moves and water jetting are effective according to the location of the fire, this study examined the automatic fire-tracking water cannon system and aan indoor hydrant system, such as water jet centered directivity, water jet range maintainability and water jet shape uniformity. First, an examination to find the center of fire accurately from this system design showed that the water jet centered test was accurate. Second, the water jet range test results showed that when water is jetted at the maximum water jet radius, the water jet shows an inaccurate result but within the allowable tolerance range. Finally, the water-jet shape test result confirmed that there are no problems in setting the block from the algorithm design.
Key Words: Water jet experiment, Road tunnel, Nozzle position control, Hydrant system, Fire extinguish method
