Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention uses an observation machine to monitor fish schools such as fish reefs, set nets and cages. Related to fishery monitoring system, especially for fisheries with observation equipment using fish finder Regarding monitoring system.

[0002]

[Prior art]

  A conventional fish finder has a memory and an oscillator connected to a control device and Ultrasonic transducer connected to the vessel, amplifier connected to this ultrasonic transducer, An A / D converter connected to the amplifier, and the output of the A / D converter is a controller Is input to the image conversion means built in, and the output of this image conversion means is input to the display device. I was getting stronger.

[0003]   The output of the A / D converter is input to the comparator, and the output of this comparator is a numerical value. It is input to the converter, and the output of this numerical converter is input to the display device. I was there.

[0004]   In such a configuration, when an oscillation signal is input from the control device to the oscillator, The vibrator applies the transmission output to the ultrasonic vibrator, and the ultrasonic wave is emitted into the water from the ultrasonic vibrator. The reflected echo of the ultrasonic wave is received by the ultrasonic transducer and amplified by the amplifier. Then, it is converted into a digital echo signal by the A / D converter. Also, this digital The echo signal is input to the image conversion means of the control unit, converted into an image signal, and recorded. Image signal once stored in the memory, and the image signals stored in this memory are sequentially read out and displayed on the display device. It was designed to be displayed on the display (for example, see Patent Document 1).

[0005]   An example of a conventional fishery monitoring system for monitoring a school of fish is a battery onboard a ship. And the image display control device is installed and connected to this image display control device by a cable. And the camera eye that was stored with the floodlight in a waterproofed capsule, A reel and a guide roller for moving the camera eye up and down with respect to the sea, and the case described above. It has first and second swivel connectors for preventing the twisting of the cable.

[0006]   In such a configuration, first, using a fish finder installed on the bottom of the ship, After confirming the school of fish, etc., connect to the cable from the sea where the school of fish, etc. was confirmed. The capsule containing the is dropped into the sea, and the image captured by this camera eye The fish school etc. were monitored (for example, refer to Patent Document 2).

[0007]   In addition, as another example of the conventional fishery monitoring system for monitoring fish in the sea, Inside the surveillance buoy that floats above the water surface, the surveillance camera and this surveillance camera Control all of the surveillance buoys, such as signalizing the underwater image captured by LA The control device was installed. Furthermore, inside the monitoring buoy, Receiving the operation signal from the above and transmitting the image data signalized by the control device. Power is supplied to the mobile phone mechanism that transmits to the image display control device side and all circuits. Battery was installed.

[0008]   And this conventional fishery monitoring system uses an image display system connected to a telephone line. Connected to the control device of the monitoring buoy via the mobile phone mechanism by the control device, The underwater image captured by the surveillance camera installed on the surveillance buoy is used by the mobile phone mechanism. The image display control device is configured to transmit to the image display control device side (see, for example, Patent Literature 3).

[0009]   In another example of a conventional fishery monitoring system, a fixed system installed in the sea is used. A monitoring buoy was installed along the line net so that it could float on the sea surface.

[0010]   The surveillance buoy has a surveillance camera for taking an underwater image of a desired position in the stationary net. Mela was connected by a cable.

[0011]   Then, the image taken by the surveillance camera is installed in the surveillance buoy. A mobile phone installed in the surveillance buoy that has been converted into an image data signal by the control device Transmission from the telephone mechanism to the image display control device on land via telephone line Was there.

[0012]   In addition, the surveillance camera is supplied with power to the main circuit such as a control device in the surveillance buoy. A battery to be supplied and a pocket for receiving instructions from the image display control device. Ring mechanism, a ring tone detection circuit that detects the ring tone of this pager mechanism, and A power supply driving unit that drives the power supply by the ring tone detected by the signal detection circuit is arranged. There is. Then, a telephone line is used from the image display side for the power supply drive unit. When a pager call is made and the pager mechanism receives it, the ring tone is detected. The road detects the ringing tone, and the power supply drive unit controls the monitoring camera and the control device. It was controlled to supply power to the main circuit.

[0013]   Furthermore, the control device controls the amount of image data sent to the image display control device. Set the power retention time of the main circuit of the surveillance camera and the control device according to The control signal for setting the power supply holding time is output to the power supply driving unit. I was there. Therefore, when the transmission of the image data is completed, the power supply to the monitoring buoy is It was supposed to be controlled so that the salary would be stopped.

[0014]   Furthermore, the monitoring buoy has a GPS (Global Positioning System) The fishery monitoring system and the target of monitoring are installed. It becomes possible to grasp the position of the fixed net which becomes Was there.

[0015]   Also, an electromagnetic epidemic current meter for measuring the direction and flow velocity of the tidal current on the monitoring buoy, and It is also possible to connect a seawater meter that measures water temperature, salt content, oxygen content, pH value, etc. It is possible to use satellite communication instead of telephone line. It has become possible to monitor even in areas where the telephone line's radio waves do not reach. (See, for example, Japanese Patent Application No. 2002-004514).
