Roadway antifreeze solution spraying system using environment sensor
The present invention relates to a road anti-freezing solution spraying system using an environmental sensor. According to the present invention, a spraying operation of an anti-freezing solution is controlled based on a spraying standard set according to environmental information detected by an environmental sensor. In addition, if freezing or black ice is expected in a spraying area because of an air temperature and road surface moisture, or snowfall is detected, an anti-freezing solution with a standard spray amount is sprayed into a spray area to prevent the freezing or black ice in the spray area. Moreover, after the anti-freezing solution with the standard spray amount is sprayed or when vehicle traffic is detected while the anti-freezing solution with the standard spray amount is being sprayed, right before the vehicle traffic detection, the anti-freezing solution with a vehicle traffic standard spray amount, which is automatically calculated in inverse proportion to a vehicle traffic volume for the past standard time set in advance, is sprayed into the spray area, and the sprayed anti-freezing solution is spread by a vehicle. According to the present invention, the anti-freezing solution with a vehicle traffic standard spray amount is sprayed. Alternatively, an anti-freezing solution with an optimal spray amount calculated by adding or subtracting a value obtained by calculating a corrected spray amount according to a correlation between an average air temperature, an average atmospheric pressure to a maximum spray amount based on vehicle traffic, and an average wind speed, or adding or subtracting a maximum spray amount based on vehicle traffic to the corrected spray amount is sprayed. Thus, an optimum level of spraying can be controlled according to the vehicle traffic volume, and a problem of excessive consumption of an anti-freezing solution can be solved. When a pedestrian crossing the crossing is detected, the operation control of anti-freezing solution is stopped for a pre-determined time, thereby solving a problem of spraying anti-freezing solution on the pedestrian.
본 발명은 환경센서를 이용한 도로 동결방지액 분사시스템에 관한 것으로, 환경센서에 의해 감지되는 환경정보에 따라 설정되는 분사기준으로 동결방지액의 분사 작동을 제어하되 대기온도와 노면 습기에 의해 분사구역의 결빙이나 블랙아이스가 예상되거나, 강설이 감지되면 기준분사량의 동결방지액을 분사구역에 분사하여 분사구역의 결빙이나 블랙아이스를 방지하고, 기준분사량의 동결방지액이 분사된 후 혹은 기준분사량의 동결방지액이 분사되는 도중에 차량통행이 감지되면 해당 차량통행 감지 직전부터 미리 설정한 과거 기준 시간 동안의 차량통행량에 반비례하여 자동으로 산출되는 차량통행량기준 분사량의 동결방지액을 분사구역에 분사하여 분사된 동결방지액을 차량에 의해 확산시킨다. 본 발명에 따르면 차량통행량기준 분사량의 동결방지액을 분사하거나, 평균대기온도와 평균기압 및 평균풍속의 상관 관계식에 따른 보정분사량을 산출하여 차량통행량기준 최대분사량에 가감하거나 보정분사량에 차량통행량기준 최대분사량을 가감하여 산출한 최적분사량의 동결방지액을 분사하므로 차량통행량에 따라 최적 수준의 분사량 조절이 가능하고 동결방지액의 과도한 소모 문제를 해결할 수 있고, 건널목을 건너는 보행자가 감지되면 동결방지액 분사 작동 제어를 미리 정한 시간 동안 중지하므로 보행자에게 동결방지액이 분사되는 문제를 해결할 수 있다.
