1. A fishing tool loss monitoring system, comprising:
at least one buoy detachably installed in a fishing tool installed in the water, providing sensing information using at least one sensor, and providing buoy identification information and buoy position information;
a fishing vessel terminal device registering fishing tool identification information in the at least one buoy, communicating with the at least one buoy to identify the buoy position information, and providing fishing vessel information including fishing vessel identification information, fishing vessel position information, the fishing tool identification information, and the buoy position information; and
a land control center performing a function of managing the fishing tool or a fishing vessel in a preset control area, transmitting/receiving information to/from the fishing vessel terminal device or the buoy through a communication network to gather the sensing information including underwater temperature information and overwater temperature information from the buoy during a preset time, measuring a speed of the buoy using the buoy position information when a difference between respective averages of the underwater temperature information and the overwater temperature information falls outside a preset error range, generating preliminary buoy loss information if the measured speed of the buoy falls outside a preset reference speed range, and providing buoy or fishing tool loss information when a distance between the fishing vessel and the buoy falls outside a preset fishing tool working radius using the fishing vessel position information and the buoy position information according to the generation of the preliminary buoy loss information, wherein
when the distance between the fishing vessel and the buoy using the fishing vessel position information and the buoy position information falls within the preset fishing tool working radius after the preliminary buoy loss information is generated, the land control center releases the generation of the preliminary buoy loss information and provides buoy position change information due to a tide.
