Description

Aquaculture feeder and feeding method {SHIP FOR FISH FEEDING AND METHOD OF FISH FEEDING}

The present invention relates to a feeder line and a feeding method that can be used to feed in a farm, and more particularly to a technology for adjusting the feed amount by grasping and reflecting the environmental conditions related to fish ecology around the farm. It is about.

Due to marine pollution and the overfishing of marine products, the catches are gradually decreasing, and there are many transitions from catching to raising fisheries.

The farms can be operated in various forms, such as floating cages that form a floating net around all sides and bottoms in a certain area of the sea, and coastal cages that surround the sides of a relatively shallow coastal sea area. Can be.

Coastal cage farms are often installed in large areas for management efficiency. However, manpower and time are required for farming in such a large area. For example, in the aquaculture business, it is necessary to increase the weight of aquaculture fish quickly by feeding the feed in a timely manner. In order to feed a large area, a worker loads the feed on a feeder and sprinkles the feed on the sea. It requires a lot of manpower and time to operate in such a way that the cost is lowering the rate of return.

In addition, although the feed is often distributed and administered over a large sea level, this feeding method is inefficient in feeding efficiency in that the fish are not evenly distributed in the sea area and can change frequently depending on time and weather conditions. In addition to lowering, in some cases, pollution of the seabed can cause long-term social costs of cage farming.

In order to reduce this problem, the feed can be adjusted according to the experience of the person in charge, or the diver can visually check the feeding situation in the water, but it is difficult to obtain rich experiences, and it is more expensive to operate in this way. It is difficult to enter a lot of manpower, and when the weather conditions deteriorate, this method is also difficult to use.

Therefore, it would be nice to know in real time where the fish are gathered without having to rely on experienced or divers, and to control feed rates differently between places in the farm.

For example, the most important environment for aquaculture is water temperature, salinity, etc. Since aquatic organisms are transgenic animals, the body temperature changes according to the temperature of the surrounding environment, so the fish's preferred temperature varies depending on the species and the fish's favorite temperature. In the bodies of water, there is a need to increase the amount of feed.

Similarly, fish that prefer brackish water will gather more in places with lower salinity, so it may be necessary to increase feed in low salinity waters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 shows the configuration of the feeder for aquaculture forming an embodiment of the present invention.

The feeder hull is provided with a feed storage unit and a feed discharge device connected to the feed storage room to discharge the feed out of the hull, and a feed system that provides a feed release signal to the feed ejector, a wireless communication unit coupled to the computer system, GPS receiver, underwater environment measurement unit is provided.

The underwater environment measuring unit includes a salinity sensor and a temperature sensor.

Therefore, the salinity sensor and the temperature sensor introduced into the water from the bottom or part of the hull when operating the feed line can measure the temperature and salinity in the water area with the feed line in real time.

The measured values are input to a computer system corresponding to the feed control unit of the present invention combined with an underwater environment measuring unit, and the computer system according to the relative distribution or distribution table of a particular fish species considering the previously inputted temperature salinity. Estimate the relative distribution of fish in the water body. In addition, by calculating the relative distribution of the fish by multiplying the degree of activation of the feeding activity of the fish at the temperature and salinity, the estimated amount of feed required at the corresponding position (coordinate) of the farm is calculated.

Predetermined feed requirements produce an output signal (a deceleration signal) of the computer system that is proportional to it, and this output signal is multiplied or added to the feed ejector opening base signal periodically generated at certain distances or movements of the feed line in the computer system. The form is reflected.

Eventually, the final output signal to the feed ejector of the computer system according to the expected feed requirement is the magnitude of the basic signal plus or minus the multiplier signal, and the final output signal enters the control unit for the feed ejector and the sensor Release the feed into the water by the amount of feed that is appropriate for the water in which it is collected.

This embodiment corresponds to the case in which the feed ejector automatically releases feed from the feeder line, but in the case of the operator manually operating the feed ejector, the final output signal for the feed ejector of the computer system according to the feed demand is determined. A display device that can be viewed by the operator may be displayed as a numerical value or a relative size graph on the monitor screen, and the operator may manually operate in consideration of the display to release the amount of feed at each feed release position.

Referring to FIG. 2, a feed line different from the embodiment of FIG. 1 is shown, and the feed line is provided with an unmanned driving system that is capable of unmanned operation as compared with the embodiment of FIG. 1.

The feeder 100 has a hull like a normal ship, a fuel tank 23 containing a battery or fuel for the operation of the hull, an engine 21 and a steering portion 31 that are driven to generate actual power. Etc., and in addition to the feed storage chamber 13 and the feed storage chamber 13 in the hull part, the feed ejector 11, the engine and the steering and the feed ejector to discharge the feed out of the hull can be controlled manually and automatically. Computer system 40 is coupled to the control unit (15, 25, 35) and the wireless communication unit 70, the camera 60, the GPS receiver 50 is installed to look around the hull is made .

The hull may vary in size depending on the size of the farm and the circumstances of management, but can be made into small hulls, usually 1 to 5 tonnes. The basic configuration of the hull is provided with an engine 21 and a steering portion 31 that can move the ship basically like a normal hull, and is provided with a space below the deck and a relatively small space above the deck. The feed storage room 13 and the feed discharger 11 may be installed separately from the cabin around the space below the deck or cabin above the deck. The cabin is made by including a window to avoid the wind and rain and to look out, may form a boarding space when boarding the operator, or may be a space where various electronic devices are installed.

Controls (15, 25, 35) that control the engine, steering and feed discharger are made by combining electromechanical controls (such as solenoid valves and linear motors) with mechanical actuation (such as knob switches or levers). . Accordingly, the engine 21, the steering unit 31, and the feed discharger 11 may be controlled through an electronic and electric control unit such as a solenoid valve and a linear motor, in addition to operating a knob switch or a lever, which is a direct mechanical operation unit. . The control signal to the control unit may be a computer system 40 directly connected to the control unit or an operation panel composed of various types of electric and electronic circuits.

The computer system 40 may include a communication device such as a wireless communication unit 70 for transmitting and receiving a signal wirelessly, a GPS receiver 50, a monitor for visually displaying necessary items on the screen, and the like. Input devices such as a mouse and a touch screen of a monitor may also be combined.

Four cameras 60 are installed in the cabin above the deck so that the cameras can be reviewed and video signals of the cameras can be transmitted from the wireless communication unit 70 to the control station 300 through the computer system 40. The control station may be a desktop computer, a laptop computer or a smartphone with a built-in wireless communication unit.

And, as shown in the embodiment of Figure 1 is provided with an underwater environment measuring unit, the underwater environment measuring unit includes a salinity sensor and a temperature sensor.

Looking at the method of operating the aquaculture feeder 100, first, it is possible to consider a case in which the operator operates the aquaculture feeder 100 in the control station 300 on the ground without the boarding. In this case, the ground worker has the same engine 21, steering portion 31, and feed as boarded by the ground computer system 340 linked with the computer system 40 in the aquaculture feeder 100. The emitter 11 can be operated.

However, in this case, in order for the ground worker to grasp the situation around the feed line for farming, the feed signal for the feed line 100 for the signal of the camera 60 provided in the cabin and the measurement result of each sensor of the underwater environment measuring unit. The computer system 40 and the wireless communication unit 70 in the interior to the control station 300, the ground control station 300 receives this wirelessly to the multi-window screen of the monitor 345 of the computer system 340 on the ground To confirm.

The operation signal of the input device 343 of the terrestrial computer system 340 is transmitted to the wireless communication unit 70 and the computer system 40 of the aquaculture feeder 100 by wireless communication, and the computer system 40. The signal in the form of operating the control unit (15, 25, 35) in aquaculture feeder is to operate the engine, the steering unit and the feed ejector.

At this time, the final output signal to the feed ejector of the computer system according to the feed required amount of the display device that the operator can see, such as a numerical value or a relative size graph on the monitor screen is similar to the description of the embodiment of FIG. The actual work can be done either at the feeder computer system or at the control system. The operator of the control station may manipulate the inputs of the control computer system, taking into account its final output signal, to release the appropriately regulated feed at each feed release location on the farm.

The remote control by the association between the aquatic feeder computer system and the ground control computer system may differ in the method of communication between these computer systems, but the remote control, drone or remote between the two existing computer systems. Since it is already used a lot in the remote control in the control robot, the basic principle is well known, detailed description thereof will be omitted.

On the other hand, in bad weather such as fog, rainstorm, snowstorm, or bad vision such as night time, while maintaining the position information by the GPS receiver 50, rather than grasping by the camera 60 to operate the feed line 100 for aquaculture It may be.

In this case, the position control signal of the GPS receiver 50 in addition to the camera 60 screen or in addition to the camera 60 screen together with the measurement result of each sensor of the underwater environmental measurement unit, the ground control station 300 Wirelessly. For example, as a representative GPS receiver 50, a navigation system that is widely used for a vehicle that can use a digital map is installed on a feed line, and the screen signal of the navigation system is transferred to the computer system 40 and the wireless communication unit 70. If the navigation screen is displayed on the monitor 345 of the computer system 340 of the ground control station, the ground control station 300 feeds aquaculture feeder 100 on the map of the screen. ) Position and movement state.

On the basis of this information, if you operate the computer system 340 on the ground as in the above example, it is possible to operate a feeding device such as a feeder 100 and a feed ejector 11 for a kind of unmanned operation. do. That is, the control signal enters the computer system 40 of the aquaculture feeder 100 by the input device operation of the terrestrial computer system 340, which is controlled by the control unit 15, 25, 35. The feeder's engine, steering and feed discharger will be controlled.

In general, there is a problem with other ships, aquatic structures, and reefs, but in cage farms, there is no need to consider the entry of other uncontrolled boats. If it is, it can be displayed on the map in advance, and it can be operated while avoiding it through the GPS position information sent from the feeder.

Aquaculture feeder 100 may perform aquaculture feed feeds completely automatically without workers on the ground and in the vessel. For example, a program for determining the position of automatic operation and feed discharge to the computer system 40 in the hull, and a program for determining the final feed discharge amount in real time together with a chart or data to measure the sensor measurement value of the aquatic environment measurement unit with the feed discharge amount. Input, specify the travel time within the program, and associate the GPS position information with the operation according to the location of the ship navigation program.

Then, periodically check the timer in the computer system or a separate timer, the position information of the GPS receiver 50, the sensor measurement information of the underwater environment measuring unit in the computer system 40 to automatically form the desired driving course at a desired time. While operating the feed line 100, it is possible to perform an optimized amount of feed at that point at a desired point.

Of course, there may be a shortage of feed in the feeder or a power source required to return, so the sensor 17, 27 to determine whether the feed and the power source is normally installed to generate a sensor signal to the computer system 40 It can be input, and it can be identified through the operation program and used as a limit condition of the feeder line operation.

Therefore, the maintenance personnel usually check and feed the feeder's feed or fuel at regular intervals, and if the alarm or abnormal signal from the sensor or computer system indicates the shortage of feed or fuel, normal operation of the feeder will be stopped. This problem should be checked by the management personnel to take corrective action.

When an abnormal signal of the sensors 17 and 27 occurs, in order to allow the management personnel to immediately identify it, an alert is generated through a telephone or other communication network and the operator is contacted in the same manner as a conventional theft reporting system. In this case, the operator checks the amount of fuel or battery stored in the feed reservoir and feed tank of the feed reservoir of the aquaculture feeder that is entering or anchored in the marina and simply fills it if it is insufficient.

Combining the GPS receiver 50 and the computer system 40, and including the running program of the computer system 40 can constitute a type of automatic ship navigation system. Here, the farm area is not a problem of other ships, unlike general waters, and water structures, reefs, etc. can be avoided in the program by avoiding aquatic structures and reefs. It is easy and inexpensive to build an automatic ship navigation system for aquaculture feeders.

Although there may be a difference in function or configuration for the automatic ship navigation system, since it is already widely used for existing ship navigation, a detailed description of the operation program will be omitted, and a schematic diagram of a form feeder for forming an embodiment of the present invention will be described with reference to FIG. 3. A brief description will be given of the method of driving.

3 is an exemplary automatic travel flowchart of a feeder for aquaculture in accordance with an embodiment of the present invention.

For example, a 3 hour cycle in a farm at 20 km / h, every UK on a map or once near a predetermined intermediate destination, U turns several times with a turning radius of 100 M. Once the final destination is reached, Return to the marina, write a program to berth at the dock, measure the aquatic environment at the feeder's position at 200m intervals during operation, calculate the optimal feed volume at that location based on the measured data If you say,

In the automatic driving program, first, the time is checked every predetermined time (S10). If the time coincides with a predetermined time within a predetermined time, for example, the vehicle is operated when it is 3 o'clock, 6 o'clock, 9 o'clock, 12 o'clock, 15 o'clock, 18 o'clock, 21 o'clock, or 24 o'clock. Next, the fuel and feed amount in the feed line is checked through the sensors 17 and 27 (S20). If the fuels and feed can run over a certain amount via the information sent by the sensors 17 and 27 to the computer system 40, then the initial position after the berthing feeder, i. Save and enter in the address, and automatically start the feed ejector and engine (S40).

On the premise that a number of intermediate destinations and final destination coordinates are determined in advance by the program, initial inputs are input for the first order and the final order (S50), and the operation is performed to the intermediate destinations that match the orders in order. Start (S60), using the program and the timer during the operation to check the current position at a certain time period (S70). For example, when the first destination is reached (S80), the steering operation is performed toward the intermediate destination of the new order again while increasing the number by one in the order raising method (S60). If it reaches and reaches the maximum degree of arrival, the steering is performed to return to the marina which is the initial position (S90).

On the other hand, when the fuel and feed amount in the feed line is check through the sensor (17, 27) (S20)

When there is not enough feed or fuel, the sensor or computer system generates an alarm as mentioned in the description of FIG. 3 above (S30).

In addition, while checking the current position at a predetermined time period during operation (S70), the computer system 40 through the GPS position information, the separation distance between the input position and the current position input to a specific storage address is more than 200 meters (M) (S71) If more than 200M, that is, 200M movement is made, the computer system reads each sensor value of the underwater environment measurement unit (S71), and in advance in the computer system in a manner similar to the previous embodiments Based on the data such as the input chart, the deceleration signal and the final feed dose are determined accordingly (S75), and the appropriate electric signal is sent to the control unit of the feed ejector so that the appropriate amount of feed is made at the feed ejector. In operation S77, the current position is stored in a specific address so as to be newly input.

When the feed line arrives at the first intermediate destination from the marina, the computer system transmits the steering signal to the control unit according to the program described above and adjusts the steering gear to the left to turn to 200M in one direction perpendicular to the first straight route at the first intermediate destination. Make a U-turn approximately 100M radius to the second intermediate destination. The radius can be adjusted with the direction of the rudder or the feed line speed during steering.

When the second intermediate destination is reached, a straight route is operated in a direction opposite to the first straight route. In this case, the food is released to the water every 200M movement as described above.

After that, it continues to drive through the next intermediate destination, and when it reaches the final destination determined in this way, it returns to the dock by driving the shortest distance to the starting position where the feeder departed, and during the return process, the feed discharger is turned off to stop feeding. Do not. When the feeder arrives, it must first take the orientation that the feeder was facing. Upon returning to the initial state of origin, the computer system generates an engine stop signal and the engine is turned off, depending on the program.

The above embodiment uses a GPS device as an example of a location based service (LBS), but of course it is also possible to use other LBS technology. LBS is a general term for wireless technology and contents that provide specific information according to the changed location of an object having a wireless Internet device, and GPS positioning technology such as a GPS receiver can be considered as a class of LBS, and can be regarded as a smart phone or a wireless device. Various LBS using a portable computer device equipped with a LAN and a mobile carrier network can also be achieved. Since LBS technology is a well-known concept, it will not be described further.

According to this embodiment of the present invention, since it may be operated without risk under various environmental conditions, it is equipped with various sensors in the present invention to regularly check the water quality and environmental requirements in the farm such as salinity, temperature, hydrogen ion concentration, oxygen demand, etc. The data collected for the aquaculture business, such as the correlation between these aquaculture factors, can be collected when collected or collected under unusual circumstances, and the data of fish consumption and feeding time related data are recorded on a computer device related to the automatic feeding device. Statistics are available that can be used for scientific aquaculture operations.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the appended claims. Those skilled in the art will appreciate that.

For example, the aquaculture feeder of the present invention may be made to eat well without leaving a feed administered by installing lights on the hull or installing an acoustic signal generator to lure fishes around the feeder in the farm with light or sound.

In addition, the aquaculture feeder of the present invention further comprises a sensor for environmental conditions related to fish ecology, such as concentration or acidity (hydrogen ion concentration) for a particular nutrient, as well as water temperature sensor and salinity sensor, distribution of fish The estimation of these sensors may also be reflected in estimating the density and adjusting the feed rate.
