초록

최근 어린이 통학버스 사용이 증가함에 따라 통학버스 운전자 및 동승 보호자의 과실로 인한 사고도 큰 폭으로 증가하고 있다. 정부에서는 이를 방지하기 위한 다양한 정책들을 내놓고 있다. 이에 우리는 어린이 통학버스 사고 방지 및 안전 관리를 위한 시스템을 제안한다. 이 시스템을 이용하면 버스 운전자는 각 좌석별 어린이의 착석 여부와 안전벨트 사용 여부를 동시에 쉽게 확인할 수 있으므로 운전 중에도 어린이들의 상태에 따라 빠르게 대처 할 수 있다. 카메라로 찍히는 이미지를 실시간 분석하여 얼굴을 인식하는 기능이 있어서, 어린이들은 각자의 키에 맞게 길이가 자동 조절된 안전벨트를 사용할 수 있다. 따라서 교통사고 발생 시 발생 가능한 2차 상해를 방지할 수 있다. 또한 어린이들이 버스에서 내린 것을 확인하기 위한 슬리핑 차일드 체크 시스템과 실시간으로 어린이의 위치를 부모에게 알려주기 위한 문자 서비스도 제공된다. 라즈베리파이를 기반으로 하여 모터, 카메라, 압력센서, 블루투스 모듈 등을 이용하여 구현되었다. 이것을 버스 모형에 부착하여 일련의 기능들이 정확하게 동작함을 확인하였다.

As the use of children's school buses increases, accidents caused by the negligence of school bus drivers and ride carers have also increased significantly. To prevent such accidents, the government is coming up with various policies. We propose an accident prevention and safety management system for children's school buses. Through this system, bus drivers can easily check whether each child is seated and whether the seat belt is used, so it is possible to quickly respond to children's conditions while driving. With the ability to recognize faces by analyzing camera images, children can use a seat belt that is automatically adjusted to their height. It is therefore possible to prevent secondary injuries that may occur in the event of a traffic accident. In addition, a sleeping child-check system is provided to confirm that all children get off the bus, and a text service is provided to inform parents of their children's locations in real time. Based on Raspberry Pi, the system is implemented with cameras, pressure sensors, motors, Bluetooth modules, and so on. This proposed system was attached to a bus model to confirm that the series of functions work correctly.
