Description

[Detailed Description of the Invention] The present invention relates to a fishing bridge that is equipped on a fishing boat and used for fishing for fish species such as bonito and tuna, and more specifically, for fishing operations. This relates to a fishing bridge that can now be operated manually or automatically.

Recently, fishing boats have been equipped with fishing bridges in order to improve efficiency and save labor in fishing operations. Traditionally, fishing bridges have been widely used, with multiple fishing bridge bodies each equipped with rotating and operable fishing rods, each of which can be used to reel in a fish (from the moment the fish is hooked). There is a fishing bridge that is controlled by a single control device so that the series of operations up to loading the fish into the boat can be performed fully automatically.

However, in the case of a fully automatic type of fishing bridge as mentioned above, unnecessary operations are forced on the fishing bridge itself due to the following reasons.
This has the disadvantage that it causes energy loss and the like.

In other words, if the fish are caught intermittently (if the fish are being caught, efficient fishing operations can be performed, but even if the fish are caught only intermittently, it is necessary to make cradle movements, recasting movements, etc.) in order to attract the fish to each fishing rod. Since it is necessary to perform operations in the same way as when fishing without interruption, energy is wasted.

In addition, since it was only possible to operate automatically, it was not possible to perform appropriate operations according to the situation of the fishing spot (how well the fish were caught).
Another drawback was that it was difficult to use.

The present invention has been made to solve the problems of the prior art, and allows manual operation, semi-automatic operation, and automatic operation to be performed selectively, thereby reducing energy loss, etc., and improving usability. The purpose is to provide a fishing bridge that can be improved.

. To increase your fortune-telling.

The automatic fishing bridge according to the present invention is provided in one or more on a fishing boat,
A fishing bridge body equipped with a fishing rod that can freely rotate between a fishing position in the front and a fishing position in the rear, a remote controller that switches the rotation operation of the fishing rod to be performed manually, semi-automatically, or automatically, and semi-automatically. and a control circuit that controls the rotation of the fishing rod during operation, and the control circuit controls the fishing rod during semi-automatic operation so as to stop the fishing rod at a position where the hooked fish is pulled toward the boat side. It is.

When fishing, you can select manual operation, semi-automatic operation, or automatic operation depending on the fishing condition.

Furthermore, during semi-automatic operation, since a pulling operation is performed, hooked fish do not escape.

It has the following.

First, the fishing bridge body 1 will be explained. In addition, since the structure of each fishing bridge body and the control details described later are the same, the following 1.
The basic fishing bridge body 1 will be explained as a representative.

As shown in FIG. 2, the fishing bridge body 1 is rotatably supported by a protective case 11 that houses a hydraulic actuator (not shown) therein between a fishing position in the front and a fishing position in the rear. The fishing rod 10 is connected between a hydraulic actuator and the hydraulic pump unit 7, and is configured to include, for example, a 4-point/2-position switching solenoid valve, and the hydraulic actuator is activated by a predetermined drive command signal from the arithmetic and control device 2. The fishing rod 10 has an electromagnetic proportional valve 12 that sets the flow rate and direction of the hydraulic oil supplied to the fishing rod 10 and controls the rotational force direction, rotational speed, etc. of the fishing rod 10.

The hydraulic actuator consists of a rack and pinion mechanism, a hydraulic cylinder, etc., and uses hydraulic oil supplied from the hydraulic pump unit 7 via the electromagnetic proportional valve 12 to transmit the reciprocating motion of the rod of the hydraulic cylinder advancing and retracting to the rack. The reciprocating movement of the rack rotates the pinion, thereby rotating the fishing rod 10.

A fishing line 13 is inserted into the inside of the fishing rod 10. fishing line 13
A fishhook (not shown) is attached to the tip of the hook, and a load detector 14 for detecting the weight of the fish caught is connected to the rear end. Further, as shown in FIG. 1, the fishing bridge main body 1 is provided with a rod angle detector 15 for detecting the rotational position of the fishing rod 10 rotated as described above. Rod angle detector 1
The detection result No. 5 is provided to the arithmetic and control device 2.

Next, the remote controllers 8a and 8b will be explained.The remote controllers 8a and 8b are installed at the fishing spot and on the bridge, respectively.Their configuration is an operation connection/disconnection switch 8 that switches between starting and stopping them.
0a, 80b, function switchers 81a, 81b for selectively switching the machine of the present invention between a fully automatic operating state, a semi-automatic operating state, a manual operating state, and a stopped state; and the fishing rod 1.
It has lever angle detectors 82a and 82b that detect the setting angle of the setting lever that sets the zero rotation operation range. The remote controllers 8a and 8b are operated manually by the fishing workers, and the on/off state of the operation connection/disconnection switches 80a and 80b is controlled by the fishermen.
The switching states of the function switchers 81a and 81b and the detection results of the lever angle detectors 82a and 82b are provided to the arithmetic and control device 2, respectively.

Next, the wave height detector 60 and the hull inclination detector 61 will be explained. The wave height detector 60 detects the height between the wave surface and the fishhook as described above, and is composed of, for example, an ultrasonic sensor. The detection results of the wave height detector 60 are sent to the arithmetic and control unit 2 (more specifically, in the fully automatic operation state, the arithmetic and control unit 2
(or to the zero point/gain adjuster 50 of the analog circuit 2B in the semi-automatic operation state).

On the other hand, the hull inclination detector 61 detects the inclination of the ship determined by the rolling pitch of waves, and the detection result is similarly sent to the computing unit 28 of the arithmetic and control unit 2 in the fully automatic operation state. In the semi-automatic operation state, the signal is applied to the zero point/gain adjuster 51 of the analog circuit 2B.

Therefore, the wave height detector 60 and the hull inclination detector 6
1, and when calculating the height position of the wave surface and the fishhook by the calculator 2A or the analog circuit 2B as described later, it is possible to eliminate the inclination of the hull and the fluctuation of the height position due to the influence of waves, It becomes possible to always set the position of the fishhook at a predetermined fishing position in the sea.

Next, the arithmetic and control device 2 will be explained. This calculation control device 2 includes a calculation unit 2A, an input interface 22 which is an accessory device thereof, an A/D converter 26, and a D/A converter 47.
, a fishing speed setting device 44, a rod return speed setting device 45, a single release hook position setting device 46, and an analog circuit 2B.
Based on the detection signal given from the hull inclination detector 61, the fishing rod 10 is caused to perform a cradling motion, a single unhooking action, a double unhooking action, etc., which will be explained later, so as to ensure that a fish is caught on the fishing bridge body 1. It has become. Then, the operator addition is CP
It is composed of U, RAM, ROM, etc., and functions during fully automatic operation as shown in FIG. 1, and controls the analog circuit 2B to ensure that fish are taken into the boat. Further, the analog circuit 2B functions by itself to ensure that fish are taken into the boat in the semi-automatic operation state shown in FIG.

Next, details of the analog circuit 2B will be explained by taking the fully automatic operation state shown in FIG. 1 as an example. Analog circuit 2B
The operation device determination circuit 21 includes the operation connection/disconnection switch 80a,
The on/off signal from 80b is input, and the controller determination circuit 21 determines which remote controller is in the on state based on this input signal, that is, which remote controller is in the on state, i.e., whether the fish is being caught at the fishing spot or from the bridge. It is determined whether fishing work is being monitored, and the determination result is sent to the computing unit 2 via the input interface 22.
It is supposed to be reported to A. In FIG. 1, fishing operations are monitored from the bridge of the ship, so the computing unit 2A knows that the remote controller 8b is in the on state.

If an embodiment is adopted in which fishing operations are monitored from the bridge, it becomes possible to visually check each fishing spot from the bridge, in other words, it becomes possible for one person to monitor a large number of fishing bridge bodies 1. In order to save manpower, it is desirable to adopt an embodiment in which monitoring is carried out on the bridge of the ship, and this embodiment adopts such an embodiment.

The operating device determination circuit 21 also provides an operation command signal to the function determination circuit 23 and the detector switching circuit 24 to cause them to perform a predetermined operation based on the determination result. Here, the function determination circuit 23 includes the function switchers 81a and 81.
A function switching signal is inputted from the detector switching circuit 24, and lever angle detection signals are inputted from the lever angle detectors 82a and 82b, respectively.
3, when the determination result of the controller determination circuit 21 is a fishing spot and a function switching signal is input from the function switch 81a, the functional state of the remote controller is determined to be a fishing spot, and the controller is determined. If the judgment result of the circuit 21 is a ship's bridge and a function switching signal is input from the function switch 81b, it is judged that the functional state of the remote controller is a ship's bridge, and the judgment result is calculated via the input interface 22. It is supposed to be reported to device 2A. In FIG. 1, since the embodiment is such that monitoring is carried out on the bridge, a notification signal from the remote controller 8b is given to the computing unit 2A. Note that the determination result of the function determination circuit 23 is also provided to an output connection/disconnection switch 38, which will be described later.

On the other hand, the detector switching circuit 24 has a zero point/gain adjuster 25,
Lever angle detectors 82a, 8 via A/D converter 26
2b to the arithmetic unit 20 to cause the fishing rod 10 to select a predetermined rod angle position.
A rod angle command signal is issued to the command angle switch 40 via the /A converter 47. This command angle switch 40
The determination result from the function determination circuit 23 is also inputted to the command angle switch 40, which receives both signals and supplies a predetermined output signal to the deviation detection circuit 34. .

In addition, the computing unit 20 grasps the situation of the boat with respect to the sea surface at the time based on the signals from the wave height detector 60 and the hull inclination detector 61, eliminates the influence of this, and determines the correct position of the fishhook with respect to the sea surface. A correction amount that can be set for the fishing position is calculated, and the calculation result is provided to the addition control circuit 33.

On the other hand, the deviation detection circuit 34 is also provided with a rod angle position detection signal from the rod angle detector 15 via the zero point/gain adjuster 30, and the deviation detection circuit 34 receives both signals. In order to eliminate these deviations, in other words, a deviation cancellation command signal is issued to the PWM amplifier 37 so that the lever setting angle of the remote controller 8b and the actual angle position of the fishing rod 10 match. Then, the PWM amplifier 37 that receives this deviation cancellation command signal connects the output terminal.
A predetermined duty ratio setting command signal is issued to the electromagnetic proportional valve 12 via the disconnector 38, and the solenoid position and valve opening are set to control the outflow direction and flow rate of the hydraulic oil. Thus, the hydraulic fluid is supplied to the hydraulic pump unit 7.
The fishing rod 10 is set at a desired rod angle position by driving the actuator. The setting of the rod angle position is similarly performed when the fishing rod 10 is caused to perform a cradle operation, a pulling operation, a single release hook operation, and a double hook release operation, which will be described later.

Here, the rod angle detector 15 detects the inclination of the fishing rod 10 with respect to the horizontal plane, and the rod angle of the fishing rod 10 changes within the range shown in FIG.

The detection result of the rod angle detector 15 is also provided to a rod angle range determination circuit 32. The rod angle range determination circuit 32 detects the fishing rod 1 based on the detection signal from the rod angle detector 15.
0 is located in the rod angle position shown in FIG. 6, that is, in which operating range is the fishing rod 10 among the cradling range, single release hook range, double release hook range, pulling range, etc. shown in FIG. The control circuit 33 determines what kind of fishing operation is to be performed at that point in time, and adds the determination result to the control circuit 33.
It is designed to output to . Here, addition control circuit 3
3 is the rod angle range determination circuit 32 in the fully automatic operation state.
In addition to the determination results from , the cradle operation command signal, single release hook operation command signal, and double release hook operation command signal from the cradle operation setting device 41, single release hook operation setting device 42, and double release hook operation setting device 43 are Each of these signals is selectively given, and a correction command signal, which will be described below, is input from the arithmetic unit 2A.

Here, this correction command signal is calculated by the arithmetic unit 2A. That is, based on the detection signals from the wave height detector 60 and the hull inclination detector 61, the calculator 2A calculates
The system grasps the situation of the hull relative to the sea surface at that point in time, calculates a correction amount that can eliminate the influence of this, and sets the position of the fishing hook relative to the sea surface to the correct fishing position, and provides the calculation result to the addition control circuit 33. It has become.

Based on these signals, the addition control circuit 33 provides a predetermined control command signal to the deviation detection circuit 34 to cause the fishing rod 10 to selectively perform a cradling operation, a single unhooking operation, and a double unhooking operation. It has become.

Therefore, the deviation detection circuit 34 receiving this control command signal
In order to set the rod angle position of the fishing rod 10 to a position corresponding to this control command signal, the electromagnetic proportional valve 12 is controlled via the PWM amplifier 37 and the output connection/disconnection switch 38 in the same manner as described above. There is. The specific details of the fishing operation will be explained later and shown in FIGS. 7 and 8.

Load detector 14 connected to the rear end of fishing line 13 as described above
detects the weight of the hooked fish, and provides the detection result to the A/D converter 26, hooking determination circuit 35, and overload determination circuit 36 via the zero point/gain adjuster 31. The hooking determination circuit 35 determines whether or not a fish is hooked based on the detection signal of the load detector 14, and reports the determination result to the calculator 20 via the input interface 22. In addition, the overload determination circuit 36 determines whether or not the hooked fish weighs more than a predetermined weight, that is, whether or not the caught fish is the target species of fish to be caught. This determination result is reported to the arithmetic unit 20 via the input interface 22 and output to the output connection/disconnection switch 38. Therefore, if the hooked fish weighs more than a predetermined weight or if the fishhook is caught by a fishing worker, a cutoff command signal is issued from the overload determination circuit 36 to the output connection/disconnection switch 38. That's 10 fishing rods
The rotation operation of the fishing bridge body 1 is stopped to ensure the protection of the fishing bridge body 1 and the safety of fishing workers.

The drive control of the command angle switch 40, cradle operation setting device 41, single release hook operation setting device 42, and double release hook operation setting device 43 is performed by the computing unit 20 via the D/A converter 47. It has become. This drive control of the arithmetic unit 20 is performed by program control. The calculator 20 also receives a fishing speed adjustment command signal and a return speed adjustment command for the fishing rod 10 from a fishing speed setting device 44, a rod return speed setting device 45, and a single release hook position setting device 46 via an input interface 22. A signal and a single release hook position adjustment command signal for adjusting the single release hook range shown as the adjustment range of the single release hook range in FIG. 3 are respectively given. Setting operations on these setting devices are performed by fishing workers, and specifically, '
Adjust the speed and position programmed in the 6M calculation '1520 as appropriate depending on the species of fish to be caught (it works).

Here, the single unhooking action refers to the first snap action performed by the fishing rod 10 in order to remove the caught fish from the hook, and the double unhooking action refers to the initial snap action that is performed when the fish is not released by the single unhooking action. This refers to the snap action performed when

Next, the semi-automatic operation state will be explained based on FIG. 2. Here, we refer to semi-automatic operation and manual operation of each device of the analog circuit 2B by fishing workers located at the Takufunabashi or each fishing spot, and the details of the specific operation will be explained in Fig. 8 below. do.

In this case, the detection signals from the wave height detector 60 and the hull inclination detector 61 are supplied to the adder circuit 52 via the zero point/gain adjusters 50 and 51 connected to these, respectively. Addition circuit 5 receives both signals.
2 calculates the correction amount, applies the calculation result to the deviation detection circuit 34 as described above, and the rod angular position of the fishing rod 10 is controlled in the same manner. Note that when the waves are calm and there is no rocking or tilting of the ship, the addition control circuit 33
Since there is no need to provide a correction amount signal to the correction amount signal, in this case, the correction connection/disconnection switch 53 cuts off the correction amount signal.

In addition, in the semi-automatic operation state, a attracting operation setting device 54 operates to attract hooked fish toward the hull and prevent them from escaping.

That is, when a fishing worker who is monitoring the fishing operation of each fishing bridge body 1 from the bridge detects that a fish has been hooked based on the determination result of the hooking determination circuit 35, the hooked fishing bridge body 1
When the pulling operation setting device 54 is turned on to cause the fishing rod 10 to perform a pulling operation, it issues a pulling operation command signal to the addition control circuit 33 to set the corresponding fishing rod 10 to the pulling position. Fishing rod 10 using the operating procedure described above.
is set to the pull position. In this case, the cradle operation setting device 41, the single release hook operation setting device 42, and the double release hook operation setting device 43 are also driven by the fishing worker.

Although the specific content of the pulling operation will be described later, it refers to pulling the hooked fish toward the hull to such an extent that the head of the hooked fish is exposed above the sea surface. Therefore, if the fishing bridge main body 1 located at an arbitrary position is to be pulled in when fish are actively eating, then the fishing bridge main body 1 in question can be excluded (only a decimal number of fishing bridge main bodies 1 need to be monitored). This has the advantage of reducing the burden on fishing workers.The number of fishing bridge bodies 1 that perform the pulling action is 1.
It is needless to say that the number is not limited to this number, and an appropriate number can be selected depending on the appetite of the fish.

Next, the manual operation state will be explained based on FIG. 3.

As shown in FIG. 3, in the manual operation state, fishermen operate each fishing bridge body 1 at the fishing spot, and the specific operation of the fishing rod 10 is based on the detection result of the rod angle detector 15. This is performed by controlling the electromagnetic proportional valve 12 via the range determination circuit 32, deviation detection circuit 34, PWM amplifier 37, and output disconnector 38.

Next, the stopped state will be explained based on FIG. 4. In this stopped state, as shown in the figure, each device of the analog circuit 2B does not function, and the fishing worker rotates each fishing rod 10. Here, in the stopped state, the output connection/disconnector 38 is cut off, so that even if a fishing worker accidentally touches each device, the fishing rod 10 will not be automatically rotated. This makes it possible to prevent accidents from occurring.

For reference in the above explanation, the function switch 81a
(or 81b) and the details of the operation during each operation shown in Figures 1 to 4 are shown in Table 1 below.Then, the specific operation details for automatic and semi-automatic operation are shown in Figures 7 and 4. Explanation based on Figure 8, and fishing rod 1 at that time
The specific operation contents of 0 will be explained based on FIG.

In addition, in FIGS. 7 and 8, the horizontal axis represents time t (seconds), and the vertical axis represents the rod angle (the angular position of the fishing rod 10 from the horizontal plane,
The case where the tip of the fishing rod 10 is directed upward with respect to the horizontal plane is indicated by a plus, and the case where it is directed downward is indicated by a minus. 9 (a), (b), and (C), the horizontal axis shows time, and the vertical axis shows the fishing rod angle from the reference position of the fishing rod 10. , is an explanatory diagram of a cradling motion, a single unhooking motion, and a double unhooking motion.

First, the case of automatic operation will be explained based on FIG. 7. The computing unit 20 receives information from the remote controllers 8a and 8b via the input interface 22 and the A/D converter 26, and when it learns that a fishing operation is being carried out on the bridge, it receives the information stored in advance. Execute the fishing operation according to the fishing program.

Here, at the time of starting execution of the fishing operation, the angular position of the fishing rod 10 is at the rod standby position where the rod angle is 90° as shown in FIG. The arithmetic unit 20 makes a determination based on the detection signal.

Now, according to the fishing program, the calculator 20 first sends a predetermined drive command signal to the command angle switch 40 in order to tilt the fishing rod 10 downward so that the rod angle of the fishing rod 10 is 130 degrees at the fishing starting position. emits. Then, as described above, the deviation detection circuit 34, the PWM amplifier 37, the output connection/disconnection switch 3
8 and the electromagnetic proportional valve 12, the fishing rod 10 is rotated downward and temporarily stopped at the fishing starting position. This operation is performed at a time T shown in FIG.

It is supposed to be done internally. The fishing start position and the angle position of the fishing rod 10 during the fishing operation described below are based on the detection signals from the wave height detector 60 and the hull inclination detector 61, and are based on the inclination and height of the hull due to the influence of waves. It is adapted to be appropriately corrected each time to eliminate positional fluctuations.

Next, the computing unit 20 issues a predetermined drive command signal to the cradle operation setting unit 41, and the deviation detection circuit 34 and PWM amplifier 3
7. Drive the fishing rod 10 via the output connection/disconnection switch 38 and the electromagnetic proportional valve 12, as shown in broken lines in FIG. 4, and as shown in FIG. 9(a).
The cradle operation shown in is performed a set number of times over time T2. Here, as shown in FIG. 7, the start of time T2 is within time T, but this is due to consideration of the responsiveness of the drive system such as the electromagnetic proportional valve 12 and the hydraulic actuator. actually performs the cradling motion at time T,
It is after the elapsed time. The cycle of this cradle operation and the cradle angle are selected depending on the species of fish to be caught, and are set in the fishing program.

Note that if a fish is hooked during the execution of the cradle operation, that is, if the fish species determination circuit 35 determines that the fish is hooked as described above and reports this to the computing unit 20, the computing unit 2
0 stops the pacifying operation at that point, and issues a predetermined drive command signal to the command angle switch 40 to cause the fishing rod 10 to perform the fishing operation. Here, the trajectory of the fishing rod 10 shown by the solid line in FIG. 7 shows the movement when the fish is hooked at the start of the cradle movement, and the recasting movement that follows the cradle movement, shown by the broken line in FIG. This is performed when the fish is not hooked even after performing the cradle motion a set number of times, and this motion is performed to entice the fish to bite. This re-throwing operation is also performed by the computing unit 2 in the same manner as above.
0, and the time is T3
is set to . Furthermore, once the rethrow action is complete,
Following this, a cradling motion similar to that described above is performed.

Now, after carrying out the fishing operation, it is known that the rod angle of the fishing rod 10 has reached the single unhooking operation starting position shown in FIG. Then, the computing unit 20 issues a predetermined drive command signal to the single unhooking operation setting device 42. In this case, the fishing rod 10 performs a single hooking motion as shown by the broken line in FIG. 7 and as shown in FIG. 9(b). However, if you perform this single unhooking action, the tension on the fishing line will suddenly loosen, making it easier for the fish to come off the hook. However, if the fish still does not come off, try the multiple unhooking action described below. I will have to do it.

In this case, the calculation unit 20 determines whether the fish has been missed based on the detection signal from the load detector 14, but the calculation unit 20 determines that the fish has been lost before the fishing rod 10 reaches the single hook release start angle. In this case, a predetermined drive command signal is issued to the command angle switch 40 to control the fishing rod 10 to return to the fishing starting position. Here, the times for the fishing operation and the single unhooking operation are indicated by T 4 and T s, respectively, in FIG. 7.

Now, when the single unhooking operation is completed, according to the fishing program, the computing unit 20 causes the fishing rod 10 to perform a rod return operation to rotate the fishing rod 10 to the rear position. A signal is issued.This rod return operation is performed for a time period T6 that is continuous with the single hook release operation.

When the rod-returning operation is completed, the computing unit 20 issues a predetermined drive command signal to the double-unhooking operation setting device 43 in order to cause the fishing rod 10 to perform a double-unhooking operation. As shown in FIG. 7, this double unhooking operation is performed multiple times (four times in the illustrated example) within time T7.
This ensures that the fish will be caught. Incidentally, FIG. 9(C) shows the relationship between the rod angular position of the fishing rod 10 and time in this double unhooking operation.

According to the device of the present invention, the above-mentioned single unhooking operation and double unhooking operation ensure that the fish is dislocated, but in case the fish is not dislocated, in this case, The arithmetic unit 20 issues a predetermined cutoff command signal to the output connection/disconnection switch 38, and the fishing rod 10 is thereby stopped. In this stopped state, fishermen will remove the fish.

Next, the case of semi-automatic operation will be explained based on FIG. Note that since the operation in this case is similar to the operation in the case of automatic driving described above, the explanation of the overlapping parts will be omitted, and only the different parts will be explained.

First, a fishing worker operates the lever of the remote controller 8b in order to move the fishing rod 10 from the rod standby position to the fishing start position. Then, as described above, the electromagnetic proportional valve 12 is driven via the command angle switch 40, deviation detection circuit 34, etc.
The fishing rod 10 is placed at the fishing start position.

Next, manually turn on the pacifying operation setting device 41 and set the fishing rod 10.
The patient is caused to perform a cradling motion for a period of time T2.

If the fish is not hooked during this cradle operation, the lever is operated to stop the cradle operation and perform a recasting operation. In addition, if a fish is hooked during the cradle operation, the fish species determination circuit 35
Based on the detection result, the fishing worker who knows this operates the lever and causes the fishing bridge body 1 to carry out the fishing operation for a time T4. Then, by manually operating the single release hook operation setting device 42 and the double release hook operation setting device 43, the fishing bridge main body 1 performs the same single release hook operation and double release hook operation as described above, and the fish are brought into the boat. Take in. Furthermore, if the fish cannot be removed even after multiple unhooking operations, the fishing bridge main body 1 is similarly stopped at that point, and the fishermen are responsible for removing the fish.

In addition, when the fish bite is good and a fish is hooked on each fishing rod 10, before fishing with any fishing rod 10,
In order to perform the above-described pulling action, the fishing worker turns on the pulling action setting device 54. This pulling operation is performed for a time T as shown in FIG. and,
This time T4 is determined depending on the number of fishing workers, the appetite of the fish, etc., but in the illustrated example, it is set to about 0.8 seconds.

In the case of the present invention having the training R and one or more evils, it becomes possible to make the fishing bridge body selectively perform manual operation, semi-automatic operation, or automatic operation, so such selection can be made depending on the fishing condition. If this is the case, not only will there be no risk of energy loss as in the conventional example mentioned above, but each fishing worker will be able to work collaboratively, resulting in more efficient fishing work. This means that the user-friendliness of the fishing bridge can be greatly improved.
