PURPOSE: An early warning system of a transportation unit is provided to cope with the accident of the transportation unit early, by transmitting an accident occurrence signal promptly using a wireless communication function of a mobile terminal, when an accident occurs in the transportation unit. CONSTITUTION: An early warning system of a transportation unit includes a transportation unit state detection device(100), a mobile terminal(200) and a central server device(300). The transportation unit state detection device is installed in the transportation unit, and generates a state signal by sensing various states of the transportation unit. The mobile terminal receives the state signal of the transportation unit state detection device in real time, and warns accident information of the transportation unit directly and then generates an accident signal of the transportation unit if the sensing value of the state signal is above a predetermined accident determination reference value. The central server device receives the accident signal from the mobile terminal, and transmits an early warning signal to a server device of a corresponding government office. The transportation unit state detection device includes a transportation unit damage sensing part, a transportation unit upset sensing part, a transportation unit flooding sensing part, a transportation unit fire sensing part, a transportation unit collision sensing part and a local area network wireless communication part. The transportation unit damage sensing part is composed of an optical fiber arranged along the body of the transportation unit, and uses an electric signal value according to the shape variation of the optical fiber as a state signal. |
