Fishing tool loss monitoring system and method

A fishing tool loss monitoring method for monitoring a loss of a buoy or a fishing tool using the buoy, the fishing tool loss monitoring method comprising:

• forming, by a land control center, a LoRa-based communication channel with a fishing vessel terminal device, a managing vessel terminal device, and the buoy, the land control center periodically obtaining buoy position information and fishing vessel information in a preset control area of the land control center and detecting and indicating, on land, whether the buoy or the fishing tool is lost, the fishing vessel terminal device registering fishing tool identification information in the buoy and managing the fishing tool identification information, the managing vessel terminal device installed in a managing vessel to perform a fishery guidance or control in a control area of the managing vessel terminal device and recover the lost fishing tool through fishing tool scanning according to buoy or fishing tool loss information, and the buoy installed in the fishing tool to provide sensing information using at least one sensor;
• periodically obtaining, by the land control center, the sensing information or the buoy position information through the communication channel, gathering 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, and generating preliminary buoy loss information if the measured speed of the buoy falls outside a preset reference speed range;
• when a distance between the fishing vessel and the buoy using the fishing vessel position information and the buoy position information falls outside a preset fishing tool working radius according to the generation of the preliminary buoy loss information, generating the buoy or fishing tool loss information and transmitting the buoy or fishing tool loss information to the fishing vessel terminal device or the managing vessel terminal device, by the land control center;
• and
• 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, releasing the generation of the preliminary buoy loss information and providing buoy position change information due to a tide, by the land control center.
