Description

Application for application of Article 30, Paragraph 2 of the Patent Law has been filed December 27, 2018 website (https://isana.lighthouse-frontier.tech/, https://peraichi.com/landing_pages/view/nldts, and https://scrapbox.io/Lighthouse-Official/), September 5, 2019 website (https://www.facebook.com/Lighthouse.Frontier/), September 17, 2019 website (https://www.youtube.com/watch?v=eLEex_3zbY8, The present invention has been disclosed on the following websites: https://www.youtube.com/watch?v=WRCM-KLIUO0, https://www.youtube.com/watch?v=qUyGxF_rCXw, https://www.youtube.com/watch?v=K4pGdpukXTk, and https://www.youtube.com/watch?v=nkmMNUfuF8c), a website on September 22, 2019 (https://www.youtube.com/watch?v=Hm1PQvRpZ_I), and four other websites. On December 27, 2018, the company disclosed the present invention by providing a customer with a communication terminal capable of executing the application.

This disclosure relates to a communication terminal, a program, and a method.

There are various ways to fish, and some fishermen operate fleets in which multiple boats share different roles. Each boat in the fleet is equipped with various equipment, such as fish finders, depending on its role. Traditionally, when taking actions such as setting nets, information detected by each boat is shared between the boats via radio or network, and personnel on each boat communicate with each other.

For example, JP 2006-006217 A describes an inter-ship communication system for fishing fleets, such as a purse seine fleet made up of a fishing boat, a fish finder, and a carrier vessel, to support fishing operations by the fishing fleet. When a fish finder vessel finds a school of fish, it compresses the image captured by the fish finder into image information using an image conversion means such as a digital camera, and notifies the fishing boat of this information, along with location information, oceanographic information, and weather information, via a mobile communications network.

JP 2006-006217 A

However, in ship-to-ship communication systems like that in Patent Document 1, information is not shared within a fleet in real time, but rather, only when the fish finder vessel finds a school of fish, the fish finder images on the fish finder vessel are compressed into image information and shared with the net boat. As a result, whether or not to share fish finder images etc. depends on the judgment of the fishermen on board the fish finder vessel, which can result in communication losses and the risk of not being able to reliably share useful information. Therefore, technology that allows for more efficient information sharing within a fleet and makes it easier to make fishing decisions is desirable.

The purpose of this disclosure is to provide technology that makes it easier to make fishing decisions while efficiently sharing information within a fishing fleet.

According to one embodiment, a communication terminal is provided that is capable of communicating with an information processing device that receives from each ship that is engaged in fishing in a fleet, information sensed by the ship. The ships that make up the fleet are equipped with at least one of a position information acquisition device that acquires the ship's position, a fish finder, a sonar, and a camera that captures the situation on board in order to perform sensing. The communication terminal is equipped with a processor, a memory, and a display. The processor executes a first step of receiving from the information processing device the sensed information received from each ship by the information processing device, a second step of displaying on the display a nautical chart, an image showing the position of each ship in the fleet on the nautical chart, and information sensed by at least some of the ships in the fleet based on the received information, and a third step of displaying the information sensed by the specified ship by receiving an operation from a user to specify each ship to be displayed on the display.

According to one embodiment, a program is provided to be executed by a computer having a processor. The computer is capable of communicating with an information processing device that receives information sensed by each ship that is engaged in fishing in a fleet from each ship, and the ships that make up the fleet are equipped with at least one of a position information acquisition device that acquires the ship's position, a fish finder, a sonar, and a camera that captures the situation on board in order to perform sensing. The program causes the processor to execute a first step of receiving from the information processing device the sensed information received by the information processing device from each ship, a second step of displaying on the display a nautical chart, an image showing the position of each ship in the fleet on the nautical chart, and information sensed by at least a part of each ship in the fleet based on the received information, and a third step of displaying the information sensed by the specified ship by receiving an operation from a user to specify each ship to be displayed on the display.

According to one embodiment, a method is provided that is executed by a computer having a processor. The computer is capable of communicating with an information processing device that receives information sensed by each ship that is engaged in fishing in a fleet from each ship, and the ships that make up the fleet are equipped with at least one of a position information acquisition device that acquires the ship's position, a fish finder, a sonar, and a camera that captures the situation on board in order to perform sensing. The method includes a first step in which the processor receives from the information processing device the sensed information received from each ship by the information processing device, a second step in which the processor displays on the display a nautical chart, an image showing the position of each ship in the fleet on the nautical chart, and information sensed by at least a part of each ship in the fleet based on the received information, and a third step in which the processor receives an operation from a user to specify each ship to be displayed on the display, and displays the information sensed by the specified ship.

＜Overview＞
The following describes a fleet operation support system 1 that supports the operation of a fishing fleet.

First Embodiment
<1 Overall configuration of fleet operation support system 1>
FIG. 1 is a diagram showing the overall configuration of a fleet operation support system 1.

The fleet operation support system 1 is a system for supporting fleet operation by sharing information sensed by each ship in a fishing fleet consisting of multiple ships. As shown in FIG. 1, the fleet operation support system 1 includes a communication terminal 10 and sensing equipment mounted on multiple ships 30A, 30B, and a server 20 capable of communicating with each ship. The sensing equipment on each ship includes a fish finder 11, a sonar 12, a position information acquisition device 13, and a camera 14. The ships 30A, 30B and the server 20 are connected to each other via a network 80 so that they can communicate with each other. The network 80 is configured as a wired or wireless network.

The communication terminal 10 is a device that is installed on a ship and displays information to be shared within the fleet. Examples of the communication terminal 10 include mobile terminals that are operated by each user and compatible with mobile communication systems, such as smartphones and tablets. In addition, the communication terminal 10 may be, for example, a wearable device, a PC (Personal Computer), etc.

The communication terminal 10 is communicatively connected to the server 20 via the network 80. The communication terminal 10 is connected to the network 80 by communicating with communication devices such as a wireless base station compatible with communication standards such as 5G and LTE (Long Term Evolution), and a wireless LAN router compatible with wireless LAN (Local Area Network) standards such as IEEE (Institute of Electrical and Electronics Engineers) 802.11.

The sensing equipment installed on each vessel is a device for acquiring information useful for fishing, and includes at least one of a fish finder 11, a sonar 12, a position information acquisition device 13, and a camera 14. Each of the above sensing equipment is connected to the server 20 via the network 80 so that it can communicate with the server 20.

The fish finder 11 is a device mounted on a ship that searches for schools of fish by emitting ultrasonic waves into the sea below the ship and capturing the reflected waves. The fish finder 11 captures the underwater situation like a radar image, and displays the distribution and density of schools of fish, the sea surface, the topography of the seabed, the water depth, etc. on the screen in different shapes, intensities, and colors.

Sonar 12 is a device mounted on a ship that searches for schools of fish by emitting ultrasonic waves into the ocean around the ship and capturing the reflected waves. Sonar 12 captures the underwater situation like a radar image, and displays images of schools of fish and the ocean floor on the screen in different shapes, intensities, and colors.

The location information acquisition device 13 is a sensor mounted on the ship that detects the ship's position, such as a GPS (Global Positioning System) module. The GPS module is a receiving device used in a satellite positioning system. In a satellite positioning system, signals are received from at least three or four satellites, and the current position of the ship on which the GPS module is mounted is detected based on the received signals.

The camera 14 is a device that is installed on the boat to photograph the situation on the boat. For example, the camera 14 is installed on the top of a fishing boat to photograph the operations of sending out and reeling in the net, and to photograph the catch.

The sensing equipment installed on each ship is not limited to the above devices, but may also include water temperature sensors that measure seawater temperature, anemometers that measure wind direction and speed, etc.

The server 20 is a device that manages the information received from each ship. The server 20 is a computer connected to the network 80.

As shown in FIG. 1, the server 20 includes a communication IF 22, an input/output IF 23, a memory 25, a storage 26, and a processor 29.

The communication IF 22 is an interface for inputting and outputting signals so that the server 20 can communicate with external devices. The input/output IF 23 functions as an interface with an input device for accepting input operations from the user and an output device for presenting information to the user. The memory 25 is for temporarily storing programs and data processed by the programs, etc., and is a volatile memory such as a DRAM (Dynamic Random Access Memory). The storage 26 is a storage device for saving data, such as a flash memory or a HDD (Hard Disc Drive). The processor 29 is hardware for executing a set of instructions written in a program, and is composed of an arithmetic unit, registers, peripheral circuits, etc.

<1.1 Configuration of communication terminal 10>
FIG. 2 is a block diagram of the communication terminal 10 constituting the fleet operation support system 1 of the first embodiment. As shown in FIG. 2, the communication terminal 10 includes a plurality of antennas (antenna 111, antenna 112), a wireless communication unit (first wireless communication unit 121, second wireless communication unit 122) corresponding to each antenna, an operation reception unit 130 (including a touch-sensitive device 131 and a display 132), a voice processing unit 140, a microphone 141, a speaker 142, a storage unit 170, and a control unit 180. The communication terminal 10 also has functions and configurations (e.g., a battery for storing power, a power supply circuit for controlling the supply of power from the battery to each circuit, a position information sensor such as a GPS module, etc.) that are not particularly shown in FIG. 2. As shown in FIG. 2, each block included in the communication terminal 10 is electrically connected by a bus or the like.

The antenna 111 emits the signal emitted by the communication terminal 10 as a radio wave. The antenna 111 also receives the radio wave from space and provides the received signal to the first wireless communication unit 121.

The antenna 112 emits the signal emitted by the communication terminal 10 as a radio wave. The antenna 112 also receives the radio wave from space and provides the received signal to the second wireless communication unit 122.

The first wireless communication unit 121 performs modulation and demodulation processing and the like for transmitting and receiving signals via the antenna 111 so that the communication terminal 10 can communicate with other wireless devices. The second wireless communication unit 122 performs modulation and demodulation processing and the like for transmitting and receiving signals via the antenna 112 so that the communication terminal 10 can communicate with other wireless devices. The first wireless communication unit 121 and the second wireless communication unit 122 are communication modules including a tuner, an RSSI (Received Signal Strength Indicator) calculation circuit, a CRC (Cyclic Redundancy Check) calculation circuit, a high-frequency circuit, and the like. The first wireless communication unit 121 and the second wireless communication unit 122 perform modulation and demodulation and frequency conversion of wireless signals transmitted and received by the communication terminal 10, and provide the received signals to the control unit 180.

The operation reception unit 130 has a mechanism for receiving input operations from a user. Specifically, the operation reception unit 130 is configured as a touch screen, and includes a touch-sensitive device 131 and a display 132.

Touch-sensitive device 131 accepts input operations by the user of communication terminal 10. Touch-sensitive device 131 detects the user's touch position on the touch panel, for example, by using a capacitive touch panel. Touch-sensitive device 131 outputs a signal indicating the user's touch position detected by the touch panel to control unit 180 as an input operation.

The display 132 displays data such as images, videos, and text in response to the control of the control unit 180. The display 132 is realized, for example, by an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display.

The audio processing unit 140 modulates and demodulates audio signals. The audio processing unit 140 modulates a signal provided by the microphone 141 and provides the modulated signal to the control unit 180. The audio processing unit 140 also provides the audio signal to the speaker 142. The audio processing unit 140 is realized, for example, by a processor for audio processing. The microphone 141 accepts audio input and provides an audio signal corresponding to the audio input to the audio processing unit 140. The speaker 142 converts the audio signal provided by the audio processing unit 140 into audio and outputs the audio to the outside of the communication terminal 10.

The storage unit 170 is configured, for example, with a flash memory, and stores data and programs used by the communication terminal 10. In one aspect, the storage unit 170 stores ship information 171.

Ship information 171 is information about each ship in the fleet operation support system 1. Ship information 171 includes the ship name, the ship's role, the ship's operating history, and information about the sensing equipment installed on the ship. Details will be described later.

The control unit 180 controls the operation of the communication terminal 10 by reading a program stored in the storage unit 170 and executing instructions contained in the program. The control unit 180 is, for example, an application that is pre-installed in the communication terminal 10. The control unit 180 operates according to the program to fulfill the functions of an input operation reception unit 181, a transmission/reception unit 182, a data processing unit 183, and an information display unit 184.

The input operation reception unit 181 performs processing to receive a user's input operation on an input device such as the touch-sensitive device 131. The input operation reception unit 181 determines the type of operation, such as whether the user's operation is a flick operation, a tap operation, or a drag (swipe) operation, based on information on the coordinates where the user touches the touch-sensitive device 131 with a finger or the like.

The transmission/reception unit 182 performs processing for the communication terminal 10 to transmit and receive data to and from external devices such as the server 20 in accordance with a communication protocol.

The data processing unit 183 performs calculations on the data received by the communication terminal 10 according to a program, and outputs the calculation results to a memory or the like.

The information display unit 184 performs processing such as displaying information received by the communication terminal 10 from the server 20 on the display 132. The information display unit 184 changes the display content as specified by the user. For example, the information display unit 184 displays a fish finder image and position information for one ship (or multiple ships) specified by the user.

<1.2 Functional configuration of server 20>
Fig. 3 is a diagram showing the functional configuration of the server 20. As shown in Fig. 3, the server 20 fulfills the functions of a communication unit 201, a storage unit 202, and a control unit 203.

The communication unit 201 performs processing for the server 20 to communicate with external devices.

The memory unit 202 stores data and programs used by the server 20. The memory unit 202 stores a ship information database 281, a sensing result database 282, etc.

The ship information database 281 is a database for storing information about each ship in the fleet operation support system 1. Details will be described later.

The sensing result database 282 is a database for storing information sensed by each ship, such as the ship's position information, fish finder image information, and camera images. Details will be described later.

The control unit 203 performs functions shown as various modules by the processor of the server 20 performing processing according to a program.

The reception control module 2031 controls the process in which the server 20 receives signals from external devices according to a communication protocol.

The transmission control module 2032 controls the process in which the server 20 transmits signals to external devices according to a communication protocol.

The multiple ship display module 2033 controls the process of displaying information sensed by multiple ships in the fleet on the display of the communication terminal 10. For example, the server 20 receives fish finder images acquired by the fish finders of each ship from each ship via the communication unit 201, and displays the fish finder images of the multiple ships on the display of the communication terminal 10, synchronizing them at the time of acquisition.

The ship designation reception module 2034 controls the process of receiving a command to designate a specific ship from the communication terminal 10. Specifically, the communication terminal 10 receives an operation from a user to designate a specific ship and transmits the contents of the command to the server 20, and the ship designation reception module 2034 receives the command to designate that ship.

The designated vessel display module 2035 controls the process of displaying information sensed by a vessel designated by the user on the display of the communication terminal 10. For example, when a user designates a fish finder vessel, the display of the communication terminal 10 used by the user displays location information sensed by the fish finder vessel, fish finder images, sonar images, camera images, and the like.

<2 Data Structure>
FIG. 4 is a diagram showing the data structures of the ship information database 281 and the sensing result database 282 stored in the server 20.

As shown in FIG. 4, each record in the ship information database 281 includes the items "ship name," "role," "operation history," and "onboard equipment," etc.

The item "ship name" is information indicating the name of each ship in the fleet.
It is the name.

The "role" item is information indicating the role each ship plays in the fleet's operations. The roles of a ship may be recorded as, for example, a "search ship" that searches for schools of fish, a "net boat" that captures schools of fish, and a "transport ship" that stores the catch on ice and unloads it at the fishing port.

The "Operation History" item shows operation information for each ship, for example recording the time and location of operations.

The "Onboard Equipment" item is information indicating the sensing equipment installed on each vessel. For example, if the exploration vessel "Daiichi Maru" is equipped with a GPS, fish finder, sonar, and camera, record "GPS, fish finder, sonar, camera."

The server 20 updates the ship information database 281 in accordance with the operation of each ship.

Each record in the sensing result database 282 includes the items "ship name", "date and time", "location information", "fish finder image", "sonar image", "camera image", etc.

The "Ship Name" item is information used to identify each ship in the fleet.

The "Date and Time" item is information indicating the date and time when the sensing results were obtained. For example, the server 20 receives and stores the sensing results obtained by the sensing equipment of each ship at a predetermined time interval (e.g., every minute).

The "Location Information" item shows the history of location information of each ship acquired at the time of sensing. For example, the server 20 records GPS coordinates consisting of latitude and longitude as location information.

The "Fish finder footage" item shows the history of footage acquired by the fish finder on each ship and displayed on the fish finder screen. On each ship, the fish finder screen displays the results of sensing by the fish finder as footage in real time. The fish finder footage includes information such as the distribution and density of fish schools, the sea surface, the seabed topography, and the water depth, each of which is displayed in a different shape, intensity, and color.

The "Sonar Images" item shows the history of images acquired by each ship's sonar and displayed on the sonar screen. On each ship, the sonar screen displays the results of sonar sensing in real time as images. Sonar images include images of schools of fish and the ocean floor, each of which is displayed in a different shape, intensity, and color.

The "Camera Images" item shows the history of images captured by the cameras on each ship, capturing the situation on board. On each ship, the camera outputs images capturing the situation on board in real time.

The position information, fish finder images, sonar images, and camera images sensed by each ship are sequentially transmitted to the server 20 via communication with the server 20. The server 20 accumulates the above information and transmits the accumulated information to the communication terminals 10 within the fleet. This allows the sensing results sensed at any time by each ship to be shared almost in real time with each ship.

<3 Operation>
Hereinafter, with reference to FIG. 5, the process of sharing information within a fleet by the fleet operation support system 1 will be described.

Figure 5 is a flowchart showing an example of the flow of sharing information sensed by each ship constituting a fleet within a fleet using the fleet management support system 1 in the first embodiment. In the following example, a process is described in which sensing results acquired by sensing devices installed on each ship, such as the fish finder 11, sonar 12, location information acquisition device 13, and camera 14, are shared and displayed on the communication terminal 10 installed on each ship via the server 20. Note that the sensing devices are not limited to the fish finder 11, sonar 12, location information acquisition device 13, and camera 14, but may be any device that can acquire information useful for fishing.

In step S521, the server 20 receives the sensing results obtained by the sensing equipment of each ship from each ship and stores them in the memory unit. The sensing results here are information useful for fishing, such as fish finder images, sonar images, location information, and camera images obtained by sensing equipment such as the fish finder 11, sonar 12, location information acquisition device 13, and camera 14 installed on each ship. The sensing equipment of each ship (such as the fish finder 11 described above) transmits the sensing results to the server 20 by communicating with the server 20.

In step S522, the server 20 transmits information (sensing results of each ship) for sharing the sensing results of multiple ships among each ship to the communication terminal 10.

In step S511, the communication terminal 10 receives the sensing results of the multiple ships from the server 20 and displays them on the display. Specifically, based on the information received from the server 20, the communication terminal 10 displays on the display a nautical chart, an image showing the position of each ship on the nautical chart, and information sensed by at least some of the ships in the fleet.

The nautical chart shows the waterway conditions in the area where the fleet is located, such as the water depth, bottom quality, coastal topography, navigational aids, etc. The image showing the position of each ship is, for example, a ship-shaped icon, and shows the position of each ship on the nautical chart to the user. Also, each ship may be displayed with a different image.

The communication terminal 10 also divides the display into multiple areas to display the sensing results of multiple ships, and displays the sensing results of each ship in each area. For example, if a fleet is made up of three ships, the display is divided into three columns, and the sensing results of one ship are displayed in each column. In this way, the sensing results of the three ships are shared within the fleet in real time while synchronizing the time.

In step S512, the communication terminal 10 accepts an operation from the user to specify a ship from among the ships displayed on the display. For example, in step S511, the sensing results of three ships are displayed simultaneously on the display, and in step S512, the communication terminal 10 accepts an operation from the user to specify a ship from among these three ships.

In step S523, in response to an operation to designate a ship, the server 20 transmits the sensing results of the specified ship to the communication terminal 10. The sensing results of a specific ship transmitted by the server 20 in step S523 may be more detailed information than the sensing results of the same ship transmitted in step S523, or may be the same information. If the same information is transmitted as the sensing results of the same ship transmitted in step S523, step S523 may not be performed.

In step S513, the communication terminal 10 receives and displays the sensing results of the specified ship. In this way, the display of the communication terminal 10 displays the sensing results of only the ship specified by the user.

Through this series of processes, the process of sharing the information sensed by each ship in the fleet within the fleet is completed.

The above process allows the sensing results of each ship to be shared within the fleet in real time, and also allows the user to display only the sensing results of the ship he or she wishes to check. Therefore, by aggregating and sharing the sensing results of each ship, it is possible to provide useful information for determining fishing grounds and support the operation of the fleet.

<4 Screen example>
6 and 7 are diagrams showing example screens of the communication terminal 10 in the first embodiment of the present disclosure. In the following example screens, the sensing results include fish finder images, sonar images, location information, and camera images acquired by sensing devices such as the fish finder 11, sonar 12, location information acquisition device 13, and camera 14 mounted on each ship.

The example screen (A) in Figure 6 shows a situation in which sensing results from multiple ships are aggregated and displayed on a single screen and shared within the fleet in real time.

As shown in screen example (A), the display screen of the user's communication terminal 10 is divided into multiple columns, and each column displays information for one ship. In addition, for each ship, the ship name and the sensing results for that ship are displayed. For example, in screen example (A), the screen of the communication terminal 10 is divided into three columns, and each column displays information for the ships "1st Circle," "2nd Circle," and "3rd Circle." For example, the third column displays the ship name "3rd Circle," an image showing the position information of the 3rd Circle, and a sonar image of the 3rd Circle.

The communication terminal 10 may change the display mode of the screen depending on the number of ships that make up the fleet or on the user's specifications. For example, the communication terminal 10 may change the number of columns on the screen from three to two columns based on the user's settings.

The communication terminal 10 may also change the type of sensing results displayed on the screen at the user's request. For example, at the user's request, the first column displays a fish finder image and sonar image for the ship "Daiichi Maru," and the third column displays location information and sonar image for the ship "Daisan Maru."

In addition, by designating a specific ship in advance, the communication terminal 10 displays the designated ship differently from other ships. For example, as shown in screen example (A), if the user designates the ship "Third Maru" in advance, when multiple ships are displayed on the display, the ship "Third Maru" is marked with a star so that it can be easily distinguished from other ships.

This allows the sensing results of each vessel in the fleet to be efficiently shared within the fleet in real time. In addition, information that was previously only roughly understood through wireless communication, such as fish finder footage, sonar footage, location information, and camera images, can now be viewed visually in real time.

Therefore, data collected by multiple ships in a fleet can be aggregated on a single screen and shared in real time, making it possible to see the data at a glance. This eliminates communication problems that occur during purse seine and trawl fishing, and makes it easier to determine fishing grounds and operate the fishery.

Screen example (B) in Figure 6 shows a situation where the sensing results of a specified ship are displayed. Sensing results of multiple ships are displayed simultaneously on the display in screen example (A), and when one of these ships is selected, the screen transitions to screen example (B).

As shown in screen example (B), the sensing results for one specified vessel are displayed on the user's communication terminal 10. For example, if a user wants to check the fish finder screen of the search vessel (Circle 1) and specifies Circle 1 on screen example (A), the left half of the screen in screen example (B) displays the current positions of each vessel in the fleet on a nautical chart, and the right half displays sonar images and fish finder images of Circle 1 in real time. The communication terminal 10 may also highlight the position of the specified vessel on the nautical chart.

This allows the user to display only the sensing results of the ship that they wish to view in detail on the display, and share the sensing results in a way that is easy for the user to view.

The example screen (A) in Figure 7 shows a situation where the track of each ship during a specific time period is displayed according to the position information acquired by each ship. The start and end points of the specific time period may be times that are set in advance (e.g., departure time or current time), or may be any time specified by the user.

For example, as shown in the example screen (A) of FIG. 7, the display of the communication terminal 10 shows the current position of each ship and its course over the past three hours on a nautical chart. In addition, the current longitude and latitude coordinates of each ship are displayed.

This allows the real-time position of each ship in the fleet to be shared, as well as the routes taken during operations to be shared and recorded. Furthermore, by visualizing the position and route of each ship, information that was previously only roughly understood through radio communications can now be seen in real time. And because the route of each ship is continually recorded on the map, it is possible to avoid re-exploring areas that other ships have already passed through.

Furthermore, the screen example (A) in FIG. 7 further displays the following information:
(i) The communication terminal 10 receives an operation from a user to specify a specific point on the ship's wake, and displays information sensed by the ship at the time corresponding to that point. For example, as shown in the example screen (A) of Fig. 7, in response to a user's operation to specify a specific point B1 on the wake, the server 20 compares the sensing result database 282 to associate the position information of point B1 with information sensed by a ship that passed point B1, and displays to the user the time when the ship passed point B1, as well as fish finder images, sonar images, camera images, and the like at that time.

This allows the sensing results to be recorded and the sensing information to be checked at any point along the ship's track, providing useful information for operations.

(ii) When the communication terminal 10 receives an operation from the user to specify a specific point on the nautical chart, the communication terminal 10 highlights the point and displays it in association with the information sensed by each ship. For example, as shown in the example screen (A) of FIG. 7, when the user specifies B2, which is a known fishing ground, the communication terminal 10 displays the point B2 with a star to make it easy to identify, and displays it in association with the tracks of each ship.

This allows users to register the location they want to check in advance, display that location and the information sensed when each vessel is operating near that location, and make use of the records of sensing results.

This allows users to use the records of sensing results to check the ship's track at any time in the past and review information on past operations.

Screen example (B) in Figure 7 shows the stage at which a fishing record for a given vessel is created.

As shown in screen example (B) of FIG. 7, the communication terminal 10 accepts an operation from a user to create a fishing record for a specific vessel, and then associates the fishing record with the sensing results of the vessel, and records and displays information related to the fishing. For example, in screen example (B), the user inputs to the communication terminal 10 as a fishing record that he or she caught fish at point C1. At this time, the communication terminal 10 marks point C1 with a fish mark, making it easier to distinguish from other points.

The information that the user inputs when creating a fishing record includes, for example, the vessel name, time of fishing, type of fish caught, weight, quantity (fish), unit price, fishing gear, etc. The server 20 automatically associates the location where the fishing took place by matching the vessel name and time of fishing with the sensing result database 282. The user may also directly enter the location where the fishing took place as part of the fishing record.

This makes it easy to record fishing results, linking and saving the catch and sensing results for each fishing day, and allowing you to review them at any time.

The communication terminal 10 may also display on the nautical chart the track for a specified time period from the time the catch was recorded, in a manner that differs from other tracks. For example, as shown in the example screen (B) of FIG. 7, the track between point C1 where the catch was recorded and point C2 one hour from the time the catch was recorded is displayed in a specified color, so as to be different from other tracks.

This makes it easy to check the ship's course leading up to the catch, and records this information as useful information for future operations.

<Summary>
As described above, according to the first embodiment, it is possible to efficiently share information within a fishing fleet while supporting the operation of the fleet.

In the first embodiment, an example of supporting the operation of a fishing fleet while sharing sensing results within the fleet has been described. In the second embodiment, a technology is described that accumulates various information related to the operation of fishing boats and provides specific functions in response to user requests.

The specific functions include the following:
(i) The specified function is a function to reduce risks associated with the operation of the ship. Risks associated with the operation of the ship are a function of risk management of the ship or risk management of the crew.
(ii) The specific function is a function for assisting in the navigation of a fleet. The function for assisting in the navigation of a fleet is a function for automatically navigating a ship or a function for providing at least one of a nautical chart and a seabed map.
(iii) The specific function is a function for managing at least one of the fishing method, the amount of the catch, and/or the distribution of the fishery product. These will be described in detail later.

The second embodiment allows for the accumulation of various information related to fishing vessel operations and the provision of specific functions in response to user requests.

<Configuration>
<1 Overall configuration of fleet operation support system 1>
The configuration of the fleet operation support system and the configuration of the communication terminal 10 according to the second embodiment are similar to those shown in Figures 1 and 3, so they will not be described repeatedly. The configuration of the server 20B according to the second embodiment will be described below.

<1.1 Configuration of server 20B>
Fig. 8 is a diagram showing the functional configuration of the server 20B. As shown in Fig. 8, the server 20B fulfills the functions of a communication unit 201B, a storage unit 202B, and a control unit 203B.

The communication unit 201B performs processing for the server 20B to communicate with external devices.

The memory unit 202B stores data and programs used by the server 20B. The memory unit 202B stores a ship information database 281B and a sensing result database 282B, etc.

The ship information database 281B is a database for storing information about each ship in the fleet operation support system 1. Details will be described later.

The sensing result database 282B is a database for storing the sensing results obtained by each ship, such as the position information of each ship, fish finder image information, and camera images. Details will be described later.

The control unit 203B performs functions shown as various modules by the processor of the server 20B performing processing according to the program.

The reception control module 2031B controls the process in which the server 20B receives signals from external devices according to a communication protocol.

The transmission control module 2032B controls the process in which the server 20B transmits signals to external devices according to a communication protocol.

The sensing result storage module 2033B controls the process of storing the sensing results sensed by each ship. For example, the server 20B stores the location information, fish finder images, sonar images, camera information, etc. sensed by each ship in the storage unit 202B via the communication unit 201.

The request reception module 2034B controls the process of receiving commands from a user to request the provision of a specific function. Specifically, the communication terminal 10 receives an operation from a user to request the provision of a specific function, and transmits the contents of the request to the server 20B. The request reception module 2034B receives the request.

The function provision module 2035B controls the process of providing functions requested by the user. Specifically, the server 20B provides the functions requested by the user to the user's terminal based on the sensing results stored in the memory unit. For example, when the user requests a function for managing the risk of the hull, the server 20B detects whether an abnormality has occurred in each ship based on the sensing results sensed in each ship, and transmits the detection results to the user's terminal.

<2 Data Structure>
FIG. 9 is a diagram showing the data structures of the ship information database 281B and the sensing result database 282B stored in the server 20B.

As shown in FIG. 9, each record in the ship information database 281B includes the items "ship name," "ship description," and "home port," etc.

The item "ship name" is information indicating the name of each ship in the fleet.
It is the name.

The "Spec" item is information showing the main specifications of each ship. For example, the spec may store the ship's length, width, depth, planned gross tonnage, maximum payload, maximum displacement, etc.

The "Home Port" field indicates the port where each ship is based.

Each record in the sensing result database 282B includes the items "ship name", "date and time", "location information", "fish finder image", "camera image", "exhaust temperature", "wind direction and speed", "fishing record", etc.

The "Ship Name" item is information showing the name of each ship in the fleet.

The "Date and Time" item is information indicating the date and time when the sensing results were obtained. For example, server 20B receives and accumulates the sensing results obtained by the sensing equipment of each ship every minute. Examples of sensing equipment here include fish finders, location information acquisition devices, cameras, exhaust thermometers, and wind direction and speed gauges.

The "Location Information" item is information showing the real-time location information of each ship. The location information may be recorded as GPS coordinates consisting of latitude and longitude.

The "Fish finder image" item is real-time images acquired by the fish finder on each ship and displayed on the fish finder screen. The fish finder image shows the distribution and density of fish schools, the sea surface, the seabed topography, the water depth, etc., in different shapes, intensities, and colors.

The "Camera Images" item is a real-time image taken by the camera on each ship, capturing the situation on board.

The "Exhaust Temperature" item is information showing the exhaust temperature of each ship. For example, the exhaust temperature is measured in real time by an exhaust temperature sensor attached near the exhaust port of the ship's engine.

The "Wind direction and speed" item is information showing the wind direction and speed at the time each ship is sailing. Wind direction and speed are measured in real time by an anemometer attached to the ship.

The "fishing record" item is information showing the fishing record of each vessel. The fishing record may be information entered by the fisherman, information obtained from a camera image when reeling in the net, or information obtained from a device that weighs the catch.

The sensing results from each ship are transmitted in real time to server 20B via communication with server 20B, and server 20B accumulates and updates the above information.

<3 Operation>
10, 11, and 12, a process of providing a specific function requested by a user based on the sensing results stored in the server by the fleet operation support system 1 will be described below. Here, the specific function is at least one of (i) a function for reducing risks involved in the operation of a ship, (ii) a function for supporting the operation of a fleet, or (iii) a function for managing the fishing method of the catch, the catch amount, or distribution.

Example 1
FIG. 10 is a flowchart showing an example of a process flow for providing a function for managing risks to the hull as a function for reducing risks associated with ship operation.

In step S1021, server 20B receives sensing results acquired by the sensing equipment of each ship from each ship and stores them in memory unit 202B. The sensing results here are information useful for fishing, such as fish finder images, sonar images, location information, camera images, exhaust temperature, wind direction and speed, acquired by sensing equipment such as fish finders, sonar, location information acquisition devices, cameras, exhaust thermometers, and wind direction and speed meters installed on each ship. The sensing equipment of each ship transmits the above sensing results to server 20B by communicating with server 20B.

In step S1011, the communication terminal 10 receives a request from the user for a function for managing the risk of the hull. The communication terminal 10 presents a plurality of specific functions to the user, and when the user selects a function for managing the risk of the hull, the communication terminal 10 receives the request and transmits a request to the server 20B to provide the function for managing the risk of the hull.

In step S1022, the server 20B receives a request for a function for managing the risk of the hull from the communication terminal 10, and then extracts and processes the sensing results related to managing the risk of the hull from the sensing results stored in the memory unit 202B.

For example, a risk to a ship is that an abnormality may occur in the ship. Server 20B extracts the exhaust temperature of each ship as a parameter associated with the detection of an abnormality in the ship, and compares it with a preset threshold value. In other words, when the exhaust temperature of the ship differs from the expected temperature, server 20B determines that some abnormality has occurred in the ship's hull or in each device installed on the ship. When the exhaust temperature of each ship stored in memory unit 202B exceeds the threshold value, server 20B checks the sensing result database 282B to identify the ship in which the abnormality has occurred. Alternatively, server 20B may extract exhaust temperature as a parameter for abnormality detection, and use machine learning techniques to calculate the degree of deviation of the exhaust temperature of each ship stored in memory unit 202B from a preset normal value.

In step S1023, server 20B transmits the result of the abnormality detection to communication terminal 10 based on the associated sensing result. For example, in step S1022, when server 20B determines that the exhaust temperature has exceeded a threshold and an abnormality has occurred based on the exhaust temperature stored in memory unit 202B, server 20B transmits the result of the abnormality detection to each communication terminal 10 in the fleet. Server 20B may also transmit the degree of deviation of the exhaust temperature from the normal value to each communication terminal 10 in the fleet.

In step S1012, the communication terminal 10 receives and displays the result of the abnormality detection from the server 20B.

Through the above series of processes, the process of providing a function for managing risks to the ship based on the sensing results stored on the server is completed.

Here, server 20B may refer to another parameter sensed by each ship to detect that an abnormality has occurred in the hull. For example, server 20B may detect that an abnormality has occurred in each ship based on the parameter of the ship's discharged water temperature. For example, if the discharged water temperature is abnormally high or abnormally low compared to the temperature expected when operating the hull, it detects that some abnormality has occurred in the hull (for example, a specific device mounted on the hull is not operating normally). In other words, server 20B detects that an abnormality has occurred in the hull by comparing the discharged water temperature with a preset threshold value.

Server 20B may also detect the occurrence of an abnormality in each ship based on the operating time of each device of the hull and the operating sounds generated when each device is operating. For example, server 20B may detect the occurrence of an abnormality based on at least one of the operating time of the engine and the operating sounds generated when the engine is operating as a device of the hull. Server 20B compares the operating time of the engine (the cumulative operating time for which the engine is operating, or the time for which the engine is operating continuously, etc.) with a preset threshold value to determine the possibility of an abnormality occurring in the engine. Server 20B may also detect the occurrence of an abnormality in the engine by comparing the sensing results of the operating sounds of the engine with the operating sounds when the engine is operating normally and determining the degree of agreement.

Furthermore, the server 20B may detect that an abnormality has occurred in the hull based on the following sensing results.
- Oil pressure, engine RPM, battery voltage, remaining fuel, errors in fishing equipment such as fish finders, ship status information (maintenance history, failure rate, etc.)
Based on the sensing results of each ship, the server 20B detects that an abnormality has occurred in the hull and notifies the communication terminal 10 of each ship constituting the fleet. For example, in the above example, the server 20B may detect that some abnormality has occurred in the hull when the decrease in the remaining fuel level is greater than expected for the convoy's navigation. This makes it easy for each ship to share the fact that an abnormality has occurred in a ship constituting the convoy, and can urge the crew of each ship to operate the convoy under the assumption that an abnormality has occurred in the hull.

Server 20B also detects the generation of smoke by performing image recognition based on images of the hull (images taken by a camera installed on the hull), images of the equipment mounted on the hull, etc. Server 20B may detect that an abnormality has occurred in the hull due to the generation of smoke. In other words, server 20B detects that an abnormality has occurred in the hull due to the equipment mounted on the hull going into an abnormal state and generating smoke.

In addition, the server 20B may detect that an abnormality has occurred in the hull based on images taken by each ship by capturing the following as the subject of image capture:
- Images of instruments such as pressure gauges, tachometers, etc. Cameras (or communication terminals 10 equipped with cameras, etc.) are installed to capture images of these instruments mounted on the hull, and server 20B monitors the values of the instruments by performing image recognition on the images captured by these cameras. If the value of the instrument indicates an abnormal value, server 20B detects an abnormality in the hull.

As a result, the results of anomaly detection can be displayed and shared in real time with each ship in the fleet, depending on the user's request. This means that the sensing results can be utilized to detect hull anomalies early, depending on the user's request, and to support fleet operations.

Figure 10 explains the flow of providing a function for managing risks to a ship using an example of detecting an anomaly in the ship's hull. However, functions for reducing risks associated with ship operation are not limited to this, and further examples include the following:

Example 2
When the risk associated with the operation of the ship is risk management of the hull, the information processing device (server 20B) identifies the hull insurance to be provided to each ship based on at least one of the sensing results sensed on each ship, information related to the performance of each ship, and information related to the operating history of each ship, and transmits the hull insurance information to the user's terminal.

For example, when server 20B determines that an abnormality has occurred because the exhaust temperature stored in memory unit 202B has exceeded a threshold value, it identifies the ship in which the abnormality occurred, and, based on information about the ship's performance or information about its operational history, identifies hull insurance that covers damage that may occur as a result of the abnormality, and transmits the hull insurance information to the ship's terminal.

This allows sensing results to be utilized to provide appropriate ship insurance information for each ship in response to user requests.

In addition, when the risk associated with ship operation is risk management of the ship's hull, server 20B detects that each ship has collided with some object and notifies communication terminal 10, etc. For example, based on cameras, acceleration sensors, etc. mounted on each ship, server 20B detects that a ship has collided with another ship and has moved in a manner different from normal navigation. Each ship may collide with another ship or with land. Each ship may also run aground. Each ship may also collide with objects (floating objects, etc.) floating on or in the sea, such as driftwood, ice blocks, buoys, and fixed nets. Server 20B detects that each ship has collided with a ship based on cameras, acceleration sensors, position information sensors, etc. mounted on each ship.

In addition, to manage risks to the hull, server 20B detects whether each ship has capsized or is on the verge of capsizing based on the sensing results of each ship, and notifies communication terminal 10, etc. For example, server 20B detects whether the ship is tilting to an extent that would not be expected under normal navigation, based on the output of an acceleration sensor, etc., mounted on the ship.

In addition, the server 20B determines the possibility that the fishing net will be damaged when cast as a risk to the operation of the ship, and notifies the communication terminal 10, etc. of the determination result. Depending on the sea area, the fishing net may be damaged when cast. For example, if there is an artificial object such as a sunken ship on the seabed, the fishing net may be damaged if the artificial object comes into contact with the fishing net. The server 20B updates the seabed map based on the sensing results of each ship, and determines for each sea area the possibility that the fishing net will be damaged if it comes into contact with the artificial object based on the seabed map (for example, due to the presence of an artificial object such as a sunken ship on the seabed). As a result, the server 20B notifies the communication terminal 10, for example, of sea areas where each ship is present (or sea areas near each ship) where it is not desirable to cast the fishing net.

The server 20B may also determine the timing for each boat to fish or not based on oceanographic information (wave height, ocean wind, tides, etc.) and notify the communication terminal 10 of the determination result. For example, based on the prediction result of wave height in a certain fishing ground, it may determine that it is better not to fish at times when the risk of fishing is high because it would be difficult for each boat to navigate safely in that sea area.

Furthermore, if the mesh size of the fishing net is too small for the size and quantity of fish caught in the sea area, a large number of fish will be caught in the net, which may cause the net to tear. In other words, server 20B can evaluate the possibility of the fishing net tearing when cast in the sea area by comparing evaluation parameters based on the size and quantity of fish with thresholds. Server 20B predicts the size and quantity of fish to be caught in each sea area based on the sensing results of each ship (for example, information on past fishing results in each sea area). Based on the prediction results, server 20B can notify communication terminal 10 of information on sea areas where it is acceptable to cast the fishing net, and information on sea areas where the possibility of the fishing net being damaged when cast exceeds a certain value.

Example 3
When the risk associated with the operation of the ship is risk management for the crew, the information processing device (server 20B) provides at least one of a function for managing the health of the crew of each ship and a function for managing the labor of the crew to the user's terminal. The information processing device (server 20B) accumulates at least images captured by a camera capturing images of the ship's interior in a memory unit 202B as the sensing results for each ship, and identifies the health and labor conditions of the crew of each ship based on the captured images and transmits the identified results to the user's terminal. Also, it identifies the labor conditions based on whether the movements of the crew on board are predetermined actions or not.

For example, when the server 20B receives a request for crew risk management functions from the communication terminal 10, it extracts images captured by cameras on board each ship from the sensing results stored in the memory unit 202B, and analyzes the movements of each crew member using machine learning techniques to identify the health and working conditions of each crew member. For example, by generating a trained model based on images captured by cameras when the crew member's health and working conditions are deteriorating (or images captured by cameras when the crew member's health and working conditions are good), it is possible to evaluate whether the crew member's health and working conditions are appropriate based on the images captured by cameras on each ship and the trained model. Also, for example, it extracts and analyzes images captured by cameras to determine whether the movements of each crew member are appropriate at the time of reeling in the net. The server 20B transmits the analysis and identification results to the communication terminal 10 for display.

Here, server 20B may determine whether the crew's fatigue level exceeds a certain level as the crew's health and work status, and notify communication terminal 10 or the like of the determination result. For example, server 20B may store the sensing results (camera images, etc.) of the crew's movements when they are not fatigued, and the sensing results of the crew's movements when they are highly fatigued (and generate a trained model based on this information), allowing server 20B to evaluate the crew's fatigue level based on the sensing results of each ship.

Similarly, the server 20B may determine whether a crew member is sick or not and notify the communication terminal 10, etc., of the determination result.

Server 20B may also detect the occurrence of a work-related accident as a crew member's working condition, and notify the communication terminal 10 or the like of the detection result. Serious work-related accidents include a crew member falling (falling) overboard from a ship, or a crew member getting caught in a fishing net. Server 20B detects crew members based on sensing results such as images captured by cameras on each ship, detects that the crew member has fallen overboard or is caught in a fishing net, and notifies the communication terminal 10 or the like of the detection result.

This allows the sensing results to be used to understand the health and working conditions of crew members on each ship and manage risks to crew members, depending on the user's request.

In addition to the above, the server 20B may manage the status of the crew of each ship based on the following information.
Personnel availability rate Personnel wages For example, the server 20B can identify the crew availability rate based on the number of days that the crew is engaged in fishing.

Example 4
11 is a flowchart of an example of providing a function for assisting in the maneuvering of a fleet. In this example, the function for assisting in the maneuvering of a fleet is a function for automatically navigating ships.

In step S1121, server 20B receives sensing results acquired by the sensing equipment of each ship from each ship and stores them in memory unit 202B. The sensing results here are information useful for fishing, such as fish finder images, sonar images, location information, camera images, exhaust temperature, wind direction and speed, etc., acquired by sensing equipment such as fish finders, sonar, location information acquisition devices, cameras, exhaust temperature gauges, and wind direction and speed gauges installed on each ship. The sensing equipment of each ship transmits the above sensing results to server 20B by communicating with server 20B.

In step S1111, the communication terminal 10 receives a request from the user for a function for automatically navigating the ship. The communication terminal 10 presents a plurality of specific functions to the user, and when the user selects a function for automatically navigating the ship, the communication terminal 10 receives the request and transmits a request to the server 20B to provide the function for automatically navigating the ship.

In step S1122, the server 20B receives a request for a function for automatically navigating the ship from the communication terminal 10, and then extracts and processes the sensing results related to the function for automatically navigating the ship from the sensing results stored in the memory unit 202B.

For example, server 20B extracts wind speed data, wind direction data, ship speed data, the ship's current position information, and the home port position from the sensing results stored in memory unit 202B, and determines the optimal route that can reduce fuel consumption.

In step S1123, server 20B transmits information for automatically navigating the ship to communication terminal 10 based on the associated sensing results. For example, in step S1122, server 20B determines an optimal route that can reduce fuel consumption based on the sensing results stored in memory unit 202B, and in step S1123, server 20 generates the optimal route and transmits it to communication terminal 10.

In step S1112, the communication terminal 10 receives and displays information for automatically navigating the ship from the server 20B.

The above series of processes completes the process of providing the functionality for automatically navigating the ship based on the sensing results stored on the server.

In this way, information for automatically navigating the ship in response to a user's request is generated in real time and displayed to the user. Therefore, information for automatically navigating the ship can be provided in response to a user's request while utilizing sensing results.

Figure 11 explains the flow of providing a function to assist in the operation of a fleet using automatic ship navigation as an example, but the function to assist in the operation of a fleet is not limited to this, and further examples include the following processes.

Example 5
The function for assisting in the operation of a fleet is a function for providing at least one of a nautical chart and a seabed map, and the information processing device (server 20B) updates at least one of the nautical chart and the seabed map based on the sensing results sensed on each ship, and transmits at least one of the updated nautical chart and the seabed map to the user's terminal (communication terminal 10).

For example, server 20B updates a seabed map by extracting data on the state of the seabed based on the fish finder images and sonar images stored in memory unit 202B, and transmits the updated seabed map to communication terminal 10. Alternatively, server 20B updates a nautical chart by extracting data on the nautical chart based on the ship's past trajectory, and transmits the updated nautical chart to communication terminal 10.

This makes it possible to provide nautical charts or maps of the ocean floor in response to user requests while utilizing the sensing results. Here, the server 20B updates the nautical charts and maps of the ocean floor based on the results of sensing carried out at any time by each ship, and can therefore provide the communication terminal 10 with nautical charts and maps of the ocean floor based on the most recent sensing results.

In addition to the above examples, as a function for supporting the navigation of the fleet, the server 20B may predict the fuel consumption of the fleet (i.e., the cost factor of fuel cost for sailing the fleet) based on information on the tides and wind speed of the sea area, predict the catch in the sea area, and notify the communication terminal 10, etc. of the navigation method of the fleet (the navigation route, navigation speed, etc. of the fleet) based on information on other fleets fishing in the sea area. For example, when there are multiple competitors fishing in a certain fishing ground (when there are multiple fleets), for a specific fishing ground, the navigation method may be proposed to the user of the communication terminal 10, etc., based on the expected catch by arriving at the fishing ground earlier than other fleets (for example, the expected catch if there are no competitors) and the fuel consumption consumed to arrive at the fishing ground earlier (there is a possibility of consuming a large amount of fuel by increasing the fleet's navigation speed). For example, the communication terminal 10 or the like may display multiple navigation patterns including the catch (i.e., expected revenue) and fuel consumption (i.e., expected cost) on a screen, and accept the designation of the navigation pattern from the user. In this case, the communication terminal 10 or the like may control the navigation of each boat so that it automatically navigates based on the navigation method accepted from the user. In other words, the server 20B can suggest to the fisherman a navigation method that maximizes profits based on the catch and fuel consumption.

In addition, as a function to support the navigation of the fleet, weather information and sea condition information (wave height, sea wind, water temperature, etc.) may be provided to the communication terminal 10, etc. For example, as sea condition information, water temperature information may be referenced in predicting fishing grounds. In addition, when the server 20B provides the communication terminal 10, etc. with tidal current information (current prediction results) as sea condition information, it may be possible to propose or determine the navigation method of each ship based on the tidal current information. For example, the server 20B may refer to the tidal current information so that each ship can quickly reach a slow speed that is favorable for fishing.

<Other examples of functions to support fleet operation>
The server 20B may provide a function for assisting in the operation of the fleet, by outputting instructions from one of the ships in the fleet to the other ships.

Such instructions include transmitting navigation instructions from the communication terminal 10 of one of the ships in the fleet to each ship in the fleet. For example, a user on one of the ships in the fleet may specify instructions on the communication terminal 10, such as a target point (point information) to which the ship should move on a nautical chart, a route (line information) along which the ship should navigate, and a speed at which the ship should navigate. The instructions are transmitted from the communication terminal 10 of the ship to the server 20B, which then notifies each ship in the fleet. This allows each ship to accurately share the instructions from a ship. Each ship may set automatic navigation, etc., based on the instructions received in this way.

Such instructions also include sending instructions regarding the timing of fishing to each ship from the communication terminal 10 of one of the ships in the fleet. For example, assume that a user on one of the ships in the fleet specifies instructions regarding the timing of fishing, such as the timing of casting a net or the timing of hauling up the net, on the communication terminal 10. This allows the instructions from a ship to be shared with each ship, and the timing of casting the nets is shared through text information, audio, video, etc.

Example 6
FIG. 12 is a flow chart showing a process for providing a function for managing the fishing method or amount of fish caught.

In step S1121, server 20B accumulates in memory 202B information on the sea area and information on the fishing method or catch amount of a particular fish caught in that sea area based on the results of sensing on each ship. Note that communication terminal 10 may accept input of information on the catch amount from the user (such as which sea area and how much was caught) and transmit the accepted information on the catch amount to server 20B, thereby allowing server 20B to manage information on the catch amount in each sea area.

For example, server 20B accumulates information about the area where fishing took place and the fishing method or amount of a particular fish caught in that area, based on location information sensed by each boat, camera images taken when reeling in the net, or information obtained by a device for weighing the catch, for the catches caught in one fishing operation.

In step S1211, the communication terminal 10 receives a request from the user for a function for managing the fishing method or catch amount of the catch. The communication terminal 10 presents a plurality of specific functions to the user, and when the user selects a function for managing the fishing method or catch amount of the catch, the communication terminal 10 receives the request and transmits a request to the server 20B to provide the function for managing the fishing method or catch amount of the catch.

In step S1222, server 20B receives a request from communication terminal 10 for a function to manage the fishing method or catch of the catch, and then extracts from memory unit 202B information on the sea area and information on the fishing method or catch of a specific fish caught in that sea area, and processes the information.

In step S1123, server 20B determines whether the fishing method or catch volume in each sea area is appropriate, and transmits the determination result to the user's terminal. The criteria for the determination may be, for example, the fishery resource management measures in the sea area where the fishing was carried out.

In step S1112, the communication terminal 10 receives from the server 20B the judgment result as to whether the fishing method in each sea area is appropriate and displays it.

The control unit 203B of the server 20B may certify that the fishing method or catch in each sea area is appropriate based on the judgment result. For example, the server 20B manages information on the fishing method and catch permitted in each sea area in the memory unit 202B, and judges whether the fishing method and catch of the ship are appropriate (whether they are within the permitted range) based on the sensing result of each ship. In addition to checking that the catch is appropriate, the server 20B may certify the catch (such as MSC (registered trademark): Marine Stewardship Council certification, Fisheries Eco Label, Marine Eco Label (registered trademark) certification, etc.). The server 20B may certify that the catch was legitimately caught in each sea area, and may provide the user with functions for performing these certifications and consulting services for obtaining certification. For example, the server 20B may certify the catch based on a photographed image of the catch.

The above series of processes completes the process of providing functionality for managing the fishing method or catch volume of fish.

As a result, the user is shown the results of a judgment as to whether the fishing method or catch volume in each sea area is appropriate or not, in response to the user's request. This makes it possible to manage the fishing method or catch volume of fish caught while utilizing the sensing results in response to the user's request.

Figure 11 describes the process for managing the fishing method or catch volume of the catch, but the process is not limited to this and further includes the following processes.

Example 7
If the specific function is a function for managing distribution of the catch, the information processing device (server 20B) accumulates information on the catch of each vessel in memory unit 202B and provides the information on the catch to a user's terminal in association with each fishing port. A control unit 203B of server 20B provides information on the type and amount of fish caught as information on the catch to a user's terminal (e.g., a terminal of a user who purchases fish), and accepts an operation to purchase the fish from the user's terminal.

For example, server 20B stores information on the catch of each vessel in memory unit 202B and transmits the information on the catch to each fishing port. A user at each fishing port uses communication terminal 10 to input an operation to purchase the catch at an auction.

This makes it possible to facilitate distribution of the catch while utilizing the sensing results in response to user requests. In other words, by providing the server 20B with information on the catch from each ship, it becomes possible to accept operations to purchase the fish from the user's terminal, so that the fish can be purchased while each ship is returning to port (i.e., before the fish from each ship arrives at the fishing port). Here, the server 20B may notify the terminals of multiple users of the information on the fish. At each user's terminal, the user may specify the amount of money to be paid for the fish. This may allow the fish to be auctioned before it arrives at the fishing port. Therefore, it may be possible to shorten the period for the fish to be delivered from each ship to the user who purchases the fish. The server 20B may also manage information on the fish caught by each ship, the fisherman who caught the fish, the purchaser who purchased the fish, and the dealer who acquired the purchased fish through secondary distribution. For example, server 20B may record information about each distributor in the process from when a fisherman catches a fish to when the consumer consumes it, and manage this information using blockchain technology. By providing an environment for each distributor to purchase fish (e.g., a screen for processing the purchase of fish), server 20B can manage which secondary distributor the fish caught by the fisherman passed through before it was delivered to the end consumer, and provide the end consumer with traceability as to which fisherman caught the fish.

<4 Screen example>
Fig. 13 is a diagram showing an example of a screen of the communication terminal 10 according to the second embodiment of the present disclosure. Fig. 13 shows a process for providing a specific function to the user's terminal based on the sensing result stored in the storage unit 202B of the server 20B in response to receiving a request for the specific function from the user.

Screen example (A) in Figure 13 shows a situation in which multiple specific functions are presented to the user. As shown in screen example (A) in Figure 13, the display of the communication terminal 10 is divided into two areas B1 and B2, where the name of the ship is displayed in area B1, and a "function list" showing the functions that can be provided is presented to the user in area B2.

The "function list" includes a hull risk management function, a crew risk management function, an automatic navigation function, a nautical chart creation function, a fishery management function, and a fishery distribution management function. By selecting any of the functions, a request for that function is accepted. For example, when a user selects the "hull risk management" function, the display screen of the communication terminal 10 transitions to screen example (B). Note that regardless of the user's operation to select any of the above functions, the communication terminal 10 may provide the user with a specific function (display a screen for using a specific function).

Screen example (B) in FIG. 13 is a diagram showing a situation in which a hull risk management function is provided to a user in response to a user request. As shown in screen example (B), area B3 displays a notification generated based on sensing results stored in the server, and the notification is a notification regarding hull risk. For example, screen example (B) notifies the user that the ship's exhaust temperature has exceeded the normal value, posing a hull risk related to an engine abnormality. In this way, the communication terminal 10 provides the hull risk management function. Screen example (B) also has a button B4 for returning to the "Function List" screen shown in screen example (A).

Screen example (C) in FIG. 13 shows a situation in which the automatic navigation function is provided to the user in response to a user request. When the user selects the "automatic navigation" function in screen example (A), the display screen of the communication terminal 10 transitions to screen example (C).

As shown in screen example (C), area B5 displays a notification generated based on the sensing results stored in the server, and the notification is information for automatically navigating the ship. For example, screen example (C) generates an optimal route that reduces fuel consumption based on wind speed data, wind direction data, ship speed data, the ship's current position information, and the home port position stored in the memory unit, and presents information about the route to the user. Screen example (C) also has button B4 for returning to the "Function List" screen shown in screen example (A).

Screen example (D) in FIG. 13 shows a situation in which a fish catch management function is provided to a user in response to a user request. When a user selects the "fish catch management" function in screen example (A), the screen of the communication terminal 10 transitions to screen example (D).

As shown in screen example (D), area B6 displays the result of a judgment as to whether the fishing method or catch volume in each sea area is appropriate, based on the sensing results stored in the server. For example, each vessel senses the fishing gear used for the catch, the fishing method, the operation period and location, and the catch size, and stores the data in the server. Based on this information, the vessel judges whether the catch is appropriate and displays the judgment result to the user. Screen example (D) also has a button B4 for returning to the "Function List" screen shown in screen example (A).

<Summary>
As described above, according to the second embodiment, various information related to the operation of a fishing boat can be accumulated, and specific functions can be provided according to the needs of the user.

<Modification>
The server 20B may provide the information and the analysis results of the information based on the sensing results obtained by each ship as information useful for the management of the fishing business operator. The server 20B may provide a function for providing the information useful for the management to the user in a viewable manner, a function for managing the information useful for the management, and a function for analyzing the information. In other words, the server 20B may provide management information by providing a function for the user to specify specific information and compare it with various data sensed by sailing each ship (operating time of the fishing boat, fuel consumption, number of crew members, and other information).

Furthermore, server 20B generates a trained model by treating the sensing results from each of these ships as time-series data. Server 20B may use the trained model to provide consulting services for fishing activities to fishing business operators. Furthermore, a business operator providing consulting services may provide consulting services for fishing activities based on the various sensing results managed by server 20B.
