Abstract
The present invention relates to an emergency position indicating radio beacon (EPIRB) terminal for confirming positions of ships and rescuing the ships during a marine disaster in a marine search and rescue system and an apparatus and a method for monitoring an operating state of the EPIRB terminal. The EPIRB terminal comprises: a sensor unit for sensing the sinking of a ship in which the EPIRB terminal is provided; a generation unit for generating a distress message corresponding to the sensed result of the sensor unit; and a transmission unit for broadcasting a distress signal including the distress message. The sensor unit comprises: a water-pressure sensor for outputting a water-pressure detection signal by sensing the water pressure in the inside of the ship; a moisture sensor for outputting a moisture detection signal by sensing the moisture inside the ship; and a separation sensor for outputting a separation detection signal by sensing the separation of the EPIRB terminal from the ship. The sensor unit outputs a generating request signal of the distress message to the generation unit by normally sensing the sinking of the ship when the water-pressure detection signal, the moisture detection signal, and the separation detection signal are outputted.
