Disclosed is a secondary accident prevention warning system, which includes: a secondary accident prevention electronic module which is inserted into a road boundary structure such as a guard rail and generates and transmits a warning signal when there is a physical collision with the boundary structure; and an accident notification sign with a communication function. According to the present disclosure, in the secondary accident prevention warning system according to the present disclosure, an electronic module includes: an energy conversion unit configured to convert kinetic energy due to physical collision into electrical energy through a magnetic induction method; a sensing unit configured to determine whether there is an external impact on the guard rail; a control unit configured to generate an accident warning signal in the event of an impact; and a communication unit configured to transmit the accident warning signal to a notification sign. The present invention provides an alarm system which is easy to maintain and can operate even when electricity is not supplied.

    가드레일과 같은 도로 경계구조물에 삽입되어, 상기 경계구조물에 물리적인 충돌이 있는 경우 경보 신호를 생성하여 전송하는 2차사고 방지 전자모듈; 및 통신기능이 포함된 사고 발생 알림 표지판을 포함하는 2차 사고 방지 경보 시스템이 개시된다. 본 개시에 따른 2차 사고 방지 경보 시스템에서 전자 모듈은 자기유도 방식을 통해 상기 물리적인 충돌로 인한 운동 에너지를 전기 에너지로 변환하도록 구성되는 에너지 변환부; 상기 전자 모듈은 가드레일에 외부 충격이 있었는지 여부를 판단하도록 구성되는 센싱부; 충격이 있었던 경우 사고 경보 신호를 생성하도록 구성되는 제어부; 및 상기 알림 표지판에 상기 사고 경보 신호를 전송하도록 구성되는 통신부를 포함한다.
