The lower body 141 and the upper body 142 may be connected to each other by a plurality of, for example, three or more connecting rods 143 so as to be coupled to each other while allowing the formation of the openings 144. A connecting portion 148 may be provided on the bottom surface of the lower body 141 so that an end of the connecting line 130 is bundled and fixed.

The locking portion 150 allows the buoyant body 140 to be fixed and separated from the fixture 110. The locking portion 150 includes a solenoid 151 that can be installed on the buoyant body 140 as well as a groove portion 149 formed on the bottom surface of the buoyant body 140 and a reel portion The bellows member 140 can be coupled to the reel unit 120 by passing through the connection hole 121 formed at the upper end of the solenoid 151.

This allows the buoyant body 140 to be inserted into the air chambers 146 and 147 So that it can not escape particularly upward from the reel unit 120 and the fixing unit 110. [

The ultrasonic module 160 is installed to receive ultrasonic waves transmitted in the lateral direction to the buoyant body 140. As described above, the ultrasonic wave module 160 is irradiated with ultrasound waves radiated laterally through the opening 144 and reflected by the cone mirror 145 To the vertex of the cone mirror 145 at the center of the upper portion of the lower body 141 to receive ultrasound waves entering at various angles in the lateral direction. As the ultrasonic waves are transmitted and received in the lateral direction, ultrasonic waves are transmitted in advance before the ship arrives at an underwater object such as a fishing net, so that the fishing net position can be confirmed and the buoyant body 140 can be floated, It is possible to prevent the accident caused by the collision of the vehicle 140 with the vehicle.

The ultrasonic wave may be transmitted from an ultrasonic wave transmitting unit 400 provided on a ship or the like. The ultrasonic wave transmitting unit 420 may include a transmitting terminal 410 for controlling the ultrasonic wave transmission, an ultrasonic transmitter 420 for transmitting the ultrasonic wave under the control of the transmitting terminal 410 And a cable 430 for electrically or signal-connecting the transmitting terminal 410 and the ultrasonic transmitter 420. 5, the ultrasonic wave is modulated by modulating the modulator 412 through code generation of the microcomputer 411 provided in the transmitting terminal 410, amplified by the amplifier 413, and transmitted from the ultrasonic transmitter 420 .

When the ultrasonic wave is received by the ultrasonic module 160, the controller 170 separates the buoyant body 140 from the fixed body 110 and floats on the water surface in a state where the buoyant body 140 is connected to the fixed body 110 by the connection line 130 Is provided on the buoyant body (140) to control the solenoid (151) of the locking portion (150). The signal processing from the ultrasonic module 160 to the control unit 170 is performed by receiving the ultrasonic waves from the ultrasonic module 160 and performing primary amplification by the amplifier 171 and noise by the noise filter 172 Filtered by the frequency filter 174, subjected to third-order amplification by the amplifier 175, demodulated by the demodulator 176, and the like to the control unit 170 .

The battery 180 is provided on the buoyant body 140 to supply power necessary for the operation of the locking unit 150, the ultrasonic module 160 and the control unit 170. In order to prevent damage and malfunction due to seawater, , Power supply line, and various signal transmission lines can be waterproofed. When the battery 180 is a rechargeable battery, the controller 170 may be provided with a circuit for charging.

The ultrasound module 160 may include an ultrasound receiver as well as an ultrasound transmitter. Thus, the ultrasound module 160 may have a function of transmitting ultrasound waves as well as information on buoys, as well as an ultrasound receiving function. At this time, the controller 170 controls the ultrasonic module 160 to transmit a preset magnetic position signal as an ultrasonic wave through the ultrasonic module 160 when the ultrasonic wave is received by the ultrasonic module 160, and when the buoyant body 140 is not controlled In the case of floating on the water surface, it is possible to provide an alarm such as a message to a terminal (not shown) such as a mobile phone, a PC or a tablet PC predetermined by wireless communication through the wireless communication unit 191.

When the vessel or the like moves to the installation area of the underwater ultrasonic remote buoy 100 and then transmits the ultrasonic wave determined by the ultrasonic transmitter 420, the underwater ultrasonic remote buoy 100 according to the first embodiment of the present invention, And the ultrasonic module 160 receives the ultrasonic waves in the vicinity thereof. 4, the control unit 170 operates the locking unit 150 according to the ultrasonic wave reception of the ultrasonic module 160 so that the buoyant body 140 is separated from the reel unit 120 and the fixed body 110 The float body 140 floats to the water surface in a state where the float body 140 is connected to the fixed body 110 by the connection line 130 by buoyancy by the air chambers 146 and 147. At this time, the connecting line 130 is naturally released from the reel unit 120 through the upper opening side of the fixing member 110. Therefore, the recovery of the fishing net (500) is facilitated by the recovery of the buoyancy member (140).

Also, when the fishing net 500 is initially placed, the GPS coordinates are input to the transmitting terminal 410. When the fish net 500 is walked, the cord is transmitted to the ultrasonic module 160 through the ultrasonic transmitter 420 by placing a code on the underwater ultrasonic wave at about 100M of the GPS coordinates. The controller 170 analyzes the ultrasound code received through the ultrasound module 160 and compares the ultrasound code received from the ultrasound module 160 with the code stored in the ultrasound module 160. If the ultrasound code is determined to be the same as the stored ultrasound code, the controller 170 operates the solenoid 151 of the locking unit 150, So that the body (140) is separated from the fixed body (110) to float to the surface of the water.

On the other hand, when the buoyant body 140 is detached and floated on the water surface, the control unit 170 allows the light emitting unit 190 to radiate light to the outside, thereby increasing the discrimination power.

When the transmitting terminal 410 transmits the ultrasonic wave through the ultrasonic transmitter 420, the ultrasonic module 160 transmits the magnetic position signal under the control of the controller 170, So that the user can know at what point the fishing net 500 and the fishing net are located. Thus, the user determines the buoy to which the map is pulled from the report. At this time, since the inner fishing net 500 and the other fishing nets have their respective codes, it is possible to prevent the fishing net from being pulled up. The control unit 170 controls the operation of the locking unit 150 or the like to prevent the floating state of the buoyancy member 140 from being detected by the level sensor, the acceleration sensor, the position sensor, the ambient light sensor, Or a sensor capable of detecting the lifting of an object such as a water sensor or the like to provide an alarm to a terminal determined by the user through the mobile communication network by the wireless communication unit 191 such as LTE or ROLA.
