METHOD FOR SECONDARY ACCIDENT PREVENTION BASED ON MAGNETIC INDUCTION PRINCIPLE GUARD RAIL

摘要

A secondary accident prevention electronic module inserted into a road boundary structure such as a guard rail to generate and transmit an alarm signal when there is a physical collision in the boundary structure; And a secondary accident prevention warning system including an accident occurrence notification sign including a communication function. In the secondary accident prevention warning system according to the present disclosure, the electronic module includes an energy conversion unit configured to convert kinetic energy due to the physical collision into electrical energy through a magnetic induction method; The electronic module includes: 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 when there is an impact; And a communication unit configured to transmit the accident warning signal to the notification sign.
