Abstract

The road icing forecast and snow detection system using state evaluation algorithm of multi sensor optimizes snow melting system to control spread time and amount of chemical spread application This system operates integrated of contact/non-contact sensor and infrared camera. The state evaluation algorithm of the system evaluates road freezing danger condition and snowfall condition (snowfall intensity also) using acquired data such as temperature/humidity, moisture detection and result of image signal processing from field video footage. In the field experiment, it proved excellent and reliable evaluated result of snowfall state detection rate of 89% and wet state detection rate of 94%.

본 연구의 복합 센서의 상태 판정 알고리즘을 적용한 노면결빙 예측 및 강설 감지 시스템은 기존 단일 센서 만을 이용하던 기존 방식에서 벗어나, 접촉식/비접촉식 센서 및 적외선 카메라를 통합 운영하여 분사 시스템의 분사 시기와 융설액 분사량을 최적 제어한다. 시스템에 적용된 상태 판정 알고리즘은 취득한 온/습도 데이터와 수분 감지 데이터, 관측된 도로 영상의 영상처리기술 등을 이용하여 노면결빙 위험상태와 강설 상태 뿐만 아니라 강설 강도까지 구분하여 판정을 수행한다. 제작된 시스템의 현장 적용 실험에서는 강설 상태 감지율 89% 습윤 상태 감지율 94%의 우수한 판정 결과와 신뢰성을 검증하였다.
