  Hereinafter, the best mode for carrying out the fish collecting lamp apparatus of the present invention will be described in detail. First, the fish lamp device of the present invention will be described based on the embodiment (1).

  As shown in FIG. 1, the fish collection lamp device 1 of the present invention includes a fish collection lamp 10 that is mounted on the hull S and irradiates light on the sea surface, an angle varying device 20 that changes the elevation angle of the fish collection lamp 10, a pitching phenomenon and rolling. The detection means 30 for detecting the rotation angle of the hull S caused by a phenomenon or the like, and the angle varying device 20 is controlled based on the rotation angle of the hull S detected by the detection means 30 to set the elevation angle of the fish collection lamp 10 to a predetermined value. And a control means 40 for correcting the value.

  A plurality of fish lamps 10 are arranged in the horizontal direction at the upper part of the hull S so as to irradiate both sides of the hull from the bow to the stern. In the fish lamp 10, a light source is disposed on a flat light emitting diode mounting substrate. As the light source, one having directivity is used, and among them, a light emitting diode having particularly high luminous efficiency is preferably used. One kind of red light emitting diode, blue light emitting diode, green light emitting diode, etc. can be used, but it is also possible to use a combination of a plurality of light emitting diodes having different emission wavelengths, such as a red light emitting diode, a blue light emitting diode, and a green light emitting diode. is there. In this case, the light color and light emission intensity of the entire light source can be changed by adjusting the amount of current flowing through each light emitting diode. Based on operational information such as seawater color, target fish species, depth of target fish species, distance between fishlight and target fish species, changes in seawater temperature, tidal current direction and flow velocity, fishing line behavior, etc. Thus, the light color and light emission intensity of the light source can be controlled.

  The angle varying device 20 is for changing the irradiation angle of the light emitted from the fish collection lamp 10 by changing the elevation angle of the fish collection lamp 10, and as shown in FIG. It mainly comprises a rotating shaft 21 disposed on both sides of the hull toward the stern and a drive motor 26 that rotates the rotating shaft 21. A plurality of fish lamps 10 are fixedly mounted on the rotary shaft 21 via mounting members at arbitrary intervals. Both end portions 211 and 212 and the intermediate position 213 of the rotating shaft 21 are rotatably supported by the bearing 22. One end 212 of the rotating shaft 21 is connected to the output shaft 241 of the speed reducer 24 by the connecting member 23. The input shaft 242 of the speed reducer 24 is connected to the drive motor 26 by a connecting member 25. That is, when the drive motor 26 is moved, the rotating shaft 21 rotates and the elevation angle of the fish collection lamp 10 can be freely changed.

  An encoder 27 is connected to the output shaft 243 on the opposite side of the speed reducer 24. The encoder 27 is provided to accurately adjust the rotation angle of the output shaft 241 of the speed reducer 24, that is, the rotation angle of the rotation shaft 21 to a target angle, and measures the actual rotation angle of the rotation shaft 21 with a predetermined resolution. Then, the measured data is output to the control means 40 described later.

  A limit sensor 28 is fixed to the output shaft 243 on the opposite side of the speed reducer 24. The limit sensor 28 is for limiting the rotation of the rotation shaft 21 so that the rotation angle of the rotation shaft 21 does not exceed a predetermined angle or less than a predetermined angle, and is installed at both ends of an angle range in which the rotation shaft 21 can be rotated. Is done. When the rotation angle of the rotation shaft 21 is greater than or equal to a predetermined angle or less than a predetermined angle, the limit sensor 28 detects the detected signal, and the detected signal is output to the control means 40 described later. And the signal which stops rotation of the rotating shaft 21 is output by the control apparatus 40, and rotation operation | movement of the rotating shaft 21 stops. Thereby, the elevation angle of the fish collection lamp 10 is controlled within a certain range, and the irradiation angle of the light emitted from the fish collection lamp 10 is also controlled within a certain range.

The detection means 30 is for detecting the swing angle of the hull S, and is connected to the control means 40 described later, as shown in FIG. The detecting means 30 detects the rotation angle α of the hull S from the reference axis Y with respect to the lateral roll direction of the hull S as shown in FIG. As shown in FIG. 5, when the hull S rotates by the rotation angle α from the reference axis Y with respect to the lateral roll direction, the fish collection lamp 10 similarly has an angle α from the reference crawl angle β ₀ to the elevation angle β. Rotate by minutes. Therefore, the elevation angle β of the fish collection lamp 10 can be adjusted by detecting the rotation angle α of the hull S. Here, a gyroscope is generally used as the detection means 30. Gyroscopes include rotary gyroscopes and vibratory gyroscopes as mechanical types, optical fiber gyroscopes and ring laser gyroscopes as optical types, and gas type gyroscopes as fluid types. Can also be used. Then, the detection means 30 transmits the detected rotation angle α to the control means 40 every predetermined time. The detection means 30 is preferably provided one by one for controlling the port and starboard fishlights 10 respectively, but the port and starboard fishlights 10 are detected by the rotation angle α detected by one detection means 30. It is also possible to control. When the port and starboard fish lamps 10 are provided respectively, the port and starboard will respond to the influence of the pitching of the rotation angle α of the hull S from the reference axis Y with respect to the rolling direction of the hull S, respectively. It becomes possible to do. Further, when the port side and starboard fish lamps 10 are controlled by a single detection means 30, the installation space can be reduced and it can be manufactured at low cost.

  The control means 40 is for adjusting the elevation angle β of the fish collection lamp 10 by controlling the rotation angle of the rotation shaft 21 of the angle variable device 20 based on the rotation angle α of the hull S transmitted from the detection means 30. A ROM 41 for storing a preset program, a RAM 42 for storing preset data, a CPU 43 for managing and controlling data, an input port 44 for relaying data input, and data output And an output port 45 for relaying. In addition, on the input port 44 side, a sonar 61 and a fish detector 62 are connected together with the detecting means 30 so that the position in the plane direction and the position in the depth direction where the fish school exists can be detected. Yes. It is also possible to guide and collect target species (fish school) by taking output information from the sonar 61, fish detector 62, etc. into the control means 40, and controlling the elevation angle of the fish lamp 10 following the fish reaction. It becomes.

  Further, as shown in FIG. 3, the fish collection lamp 10 can be provided with a light source control means 63 for controlling the light color and emission intensity of the fish collection lamp 10. Various operation information such as the light color and emission intensity of the light source of the fish lamp 10 by the light source control means 63, the color of water in the operating sea area, the illuminance condition, the type of the target organism for fishing, the position, depth and behavior characteristics of the target organism for fishing. By controlling based on this, it is possible to efficiently collect the fish to be caught.

  The operation unit 50 is for operating the control means 40, and is composed of, for example, an operation panel formed in a box shape. The operation unit 50 includes an automatic control button 51 that automatically controls the light irradiation angle of the fish collection lamp 10 in response to the rolling of the ship, and a light irradiation angle volume 52 that manually adjusts the elevation angle of the fish collection lamp 10. Have. The light irradiation angle volume is configured such that the elevation angle β of the fish collection lamp 10 can be continuously changed by twisting the knob. In addition, the operation unit 50 is provided with a storage button 53 that can change the direction of the fish lamp 10 vertically downward (elevation angle β = 90 °) with one touch. The operation unit 50 is provided with a setting key 54 for setting the control means 40.

  Next, the control of the elevation angle β of the fish collection lamp 10 using the fish collection lamp apparatus 1 described above will be described. First, a case will be described in which the automatic control button 51 of the operation unit 50 is turned on to automatically control the elevation angle β of the fish collection lamp 10 corresponding to the roll of the ship.

When the automatic control button 51 is turned on, the detection means 30 detects the rotation angle α from the reference axis Y with respect to the horizontal shaking direction of the hull S generated when the hull S shakes. At this time, the reference axis Y is a vertical line of the hull S in the still water state, the rotation angle α = 0 in the still water state, and the reference cradle angle β ₀ is the elevation angle β in the still water state of the fish collection lamp 10. Incidentally, when the hull S is rotated by the rotation angle α from the reference axis Y relative to the roll direction of the left and right, rotating fishing light 10 also to the depression angle beta elevation from a reference line depression beta ₀ similarly angle α min. Therefore, the elevation angle β of the fish collection lamp 10 can be adjusted by detecting the rotation angle α of the hull S. And the rotation angle (alpha) detected by the detection means 30 is transmitted to the control means 40 for every predetermined time.

Then, the CPU43 of the control means 40, based on the data of the rotation angle α from the reference Y of the hull S, the rotation of the rotary shaft 21 required to correct the depression angle beta ₀ elevation relative to the depression angle beta elevation of fishing light 10 The angle is calculated, and operation instruction data is transmitted to the CPU 29 of the drive motor 26 of the rotating shaft 21. This makes it possible to always keep the elevation angle β of the fish collection lamp 10 constant according to the rolling (rolling) phenomenon or the pitching (pitching) phenomenon of the hull S. In addition, it is preferable that the control means 40 adds the structure which estimates the elevation angle (beta) of the fish collection lamp 10 from the rotation angle (alpha) of the hull S detected by the detection means 30, and controls the elevation angle (beta) of the fish collection lamp 10. Specifically, the change in the elevation angle β of the fishlight 10 is synchronized with the wave period and is expressed by the following equation (I).
β = ωt + β ₀ (I)
The angular velocity (v) shown by the following formula (II) is obtained by differentiating the above (β) once.
v = dβ / dt (II)
Furthermore, the angular acceleration (α) represented by the following formula (III) is obtained by differentiating once more.
α = d ² β / dt ² (III)
On the other hand, the change in the rotation angle α of the hull S detected by the detection means 30 already described is the same as the elevation angle β of the fish collection lamp 10 represented by the above formula (I). Therefore, the elevation angle β can be kept constant by adding to or subtracting from the current elevation angle β based on the amount of change in angular velocity, angular acceleration, and the like as described above. That is, when the elevation angle β increases, the predicted correction angular displacement θ is subtracted and corrected to a predetermined value, and conversely, when the elevation angle β decreases, the predicted correction angular displacement θ Are corrected to the predetermined value. In this case, since the elevation angle β is predicted and controlled, the elevation angle β of the fish collection lamp 10 is always kept constant according to the rolling (rolling) phenomenon or the pitching (pitch) phenomenon of the hull S. In particular, even when the amplitude period of pitching or rolling is short and the amplitude is large, the elevation angle β can always be kept constant.

  Here, an operation of calculating the corrected angular displacement θ corrected by the CPU 43 will be described. The flowchart shown in FIG. 6 is a process that is repeatedly executed every certain time (t). In step 1 (S1), the calculation of the corrected angular displacement θ is started. First, after starting, it is determined in step 2 (S2) whether or not it is the first time after power-on. If step 2 (S2) is YES, the process proceeds to step 3 (S3), and the CPU 43 performs processing for storing the data input from the detection means 30 in the RAM 42. If Step 2 (S2) is NO, that is, if it is the second time after power-on, the process proceeds to Step 4 (S4). In step 4 (S4), the CPU 43 reads the data detected by the detection means 30.

  Then, the process proceeds to step 5 (S5), the previous detection means 30 data stored in the RAM 42 is compared with the current detection means 30 data, and the corrected angular displacement θ is calculated from the time (t). To do. Next, the process proceeds to step 6 (S 6), and the read data of the detection means 30 is stored in the RAM 43. Next, in step 7 (S7), the rotation angle of the drive motor 26 is calculated from the calculated corrected angular displacement θ. In step 8 (S8), the calculated rotation angle is output to the CPU 29 that controls the drive motor 26.

  Next, a procedure for correcting the elevation angle β of the fish collecting lamp 10 performed by the CPU 29 provided in the drive motor 26 as shown in FIG. 7 will be described. First, in step 9 (S9), it is determined whether or not the drive motor 26 is rotating. If step 9 (S9) is YES, the process proceeds to step 10 (S10), and it is determined whether or not there is a correction rotation speed input from the CPU 43 of the control means 40. When step 9 (S9) is YES, the process proceeds to step 11 (S11), and it is determined whether or not the angular displacement θ as a correction value is positive. If step 11 (S11) is YES, the process proceeds to step 12 (S12) to change the current rotational speed to an angle obtained by subtracting the correction angular displacement θ. On the other hand, if step 11 (S10) is NO, the process proceeds to step 13 (S13) to change the current rotational speed to an angle obtained by adding the correction angular displacement θ. With the above-described operation, the elevation angle β of the fish collection lamp 10 can be corrected in real time and kept at a constant value at all times.

  As described above, according to the fish lamp device according to the present embodiment, the following effects can be obtained. First, as shown in FIG. 8, the fluctuation of the light irradiation angle of the fishlight 10 due to the pitching phenomenon or the rolling phenomenon can be prevented, and the direction of the fishlight 10 can be held so as to always irradiate a predetermined area of the sea. . And since there is no fluctuation | variation of the light irradiation angle of the fish-collecting lamp 10, and it can irradiate a fixed area | region, it does not disrupt fish school behavior, such as a squid, and can improve fishing efficiency significantly.

  Further, in the fish lamp device according to the embodiment (1), the elevation angle β of the fish lamp 10 can be freely changed by manual operation of the operation unit 50, so that the user can freely collect the fish lamp as shown in FIG. By operating and controlling 10 elevation angles β, it is possible to effectively realize a fish collection suitable for natural conditions such as weather, sea color, transparency, and tidal current on the day of operation. In addition, the elevation angle β of the fishlight 10 can be adjusted (corrected) in accordance with the surrounding environment that changes with time.

  For example, when fish shadow reaction information of a target fish far away from the hull S is input from the fish detector 62, the control means 30 controls the elevation angle β of the fish collection lamp 10 to the far irradiation angle by the angle variable means 20. To do. At the same time, the light source of the fish lamp 10 is controlled using the light source control means 63 so as to emit a wavelength color having high seawater permeability. Next, in order to guide the fishing target organism group to the vicinity of the hull S, the elevation angle β of the fish lamp 10 is controlled so that the irradiation area of the fish lamp 10 is gradually shifted in the hull S direction. At this time, as shown in FIG. 3, the control of the elevation angle β of the fish collection lamp 10 can be performed by inputting the reaction information of the fish finder 62 to the control means 30 and calculating / determining it.

  Then, along with the induction of the fish target group, the light target and the light intensity of the light source of the fish lamp are controlled simultaneously with the elevation angle β of the fish lamp 10, and the fish group is further guided to a catchable region. Subsequently, when the target fish group is guided to a catchable area, the automatic control button 51 of the operation unit 50 is turned on. That is, after controlling the elevation angle β of the fish collection lamp 10 so as to follow the rolling phenomenon of the hull S and stabilizing the light irradiation direction of the fish collection lamp 10, the operation (capture, catch) is performed. When the operation is finished, the storage button 53 of the operation unit 50 is turned ON, and the direction of the fish collection lamp 10 is changed to the vertically downward direction (elevation angle β = 90 °) as shown in FIG. Is controlled to a horizontal position to avoid the effects of wind pressure.

  As described above, the fish collection lamp device 1 according to the embodiment (1) of the present invention eliminates the fluctuation of the light irradiation direction of the fish collection lamp 10 due to the rolling phenomenon, and keeps the irradiation direction to the sea surface and the sea constant. This is a fishlight device that does not confuse fish school behavior and enables presumed fish collection and operation regardless of conditions such as sea level.

  In the embodiment (1), the detection means 30 detects the rotation angle α of the hull S rotated from the reference axis Y with respect to the lateral roll direction. Can be configured to detect a rotation angle rotated from the reference axis Y with respect to the longitudinal pitching direction. Then, using the data of the rotation angle with respect to the pitch direction of the hull S, the hull S corrects the value of the rotation angle α with respect to the horizontal roll direction to calculate the corrected angular displacement θ to calculate the elevation angle β of the fish lamp 10. It is also possible to control.

  Next, the fish lamp device of the present invention will be described based on the embodiment (2). As shown in FIG. 11, the fish collection lamp device according to the embodiment (2) is configured such that when a plurality of fish collection lamp apparatuses 1 are mounted on the hull S, the angle variable means 20 and the detection for each fish collection lamp 10 are detected.

  And as the detection means 30, in addition to the detection of the rotation angle α in which the hull S is rotated from the reference axis Y with respect to the lateral roll direction, the hull S is rotated from the reference axis Y with respect to the longitudinal pitch direction. A device that detects the rotation angle is used. And the correction | amendment angular displacement (theta) with respect to the elevation angle of the fish-collecting lamp 10 is calculated by adding the correction | amendment by the data of the rotation angle with respect to the pitching direction of the hull S to the value of the rotation angle (alpha) with respect to the horizontal rolling direction of the hull S, The elevation angle β of each fishlight 10 can be finely controlled.

  According to the fish lamp device 1 according to the embodiment (2), each fish lamp 10 has different effects on the light irradiation angle due to the pitching phenomenon and the rolling phenomenon depending on the position in the hull S on which it is mounted. Since it can be processed individually by the angle variable means 20, the detection means 30, and the control means 40 mounted on the fishlight 10, it is possible to make a desired correction that matches the installation location for each fishlight 10, and the fishing efficiency. Can be improved more effectively.

  In the above embodiment (2), the detection means 30 is capable of detecting the rotation angle of the hull S with respect to the pitch direction. However, the rotation angle rotated from the reference axis Y with respect to the horizontal roll direction. What detects only (alpha) may be used. Also in this case, the numerical value of the rotation angle α of the hull S from the reference axis Y with respect to the lateral roll direction of the hull S detected by the detection means 30 may be affected by other factors such as pitching. It is possible to perform fine control of the elevation angle β for each fish collection lamp 10.
