COMMUNICATION TERMINAL SYSTEM FOR REAL-TIME FISHING NET RECOGNITION FOR SMALL AND MEDIUM FISHING BOAT

摘要

The present invention provides an underwater communication device which receives fishing net state information and accurately transmits the information to a fishing boat. A sound wave underwater communication module drives an ultrasonic vibrator in the water so that a signal is generated from the ultrasonic vibrator and ultrasonic waves are received in an ultrasonic receiver by removing various disturbance sounds generated in the water through liquid (seawater) which is a medium, thereby enabling communications between a transmitter and the receiver.;COPYRIGHT KIPO 2018
