Description

The present disclosure relates to communication terminals, programs and methods.

There are various ways to fish, and there are fleet fishermen who fish while sharing roles among multiple boats. Each ship that makes up the fleet is equipped with various equipment such as a fish finder, depending on its role. Conventionally, when performing actions such as establishing a network, information detected by each ship is shared between ships by a radio or a network, and personnel between ships communicate with each other.

For example, Japanese Patent Application Laid-Open No. 2006-006217 describes an inter-ship communication system of a fishing fleet to support operations by a fishing fleet such as a purse seine fleet consisting of a net boat, a fish finder, and a carrier. When the fish finder discovers a school of fish, it compresses the image of the fish finder into image information via an image conversion means such as a digital camera, and together with location information, ocean information, and weather information, the fish finder goes through a mobile communication network. Notify to.

<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 of the records in the ship information database 281 includes an item "ship name", an item "role", an item "operation history", an item "mounted equipment", and the like.

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

The item "role" is information indicating the role that each ship plays in the operation of the fleet. The role of the ship may be recorded, for example, as a "search ship" for searching for a school of fish, a "net ship" for catching a school of fish, and a "carrying ship" for storing catch and landing it at a fishing port.

The item "operation history" indicates the operation information of each ship, and records, for example, the time and position of the operation.

The item "mounted equipment" is information indicating the sensing equipment mounted on each ship. For example, when the position information acquisition device (GPS), fish finder, sonar and camera of the search ship "No. 1 Maru" are installed, "GPS, fish finder, sonar, camera" is recorded.

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

Each of the records in the sensing result database 282 includes an item "ship name", an item "date and time", an item "position information", an item "fishfinder image", an item "sonar image", an item "camera image" and the like.

The item "ship name" is information for identifying each ship in the fleet.

The item "date and time" is information indicating the acquisition date and time of the sensing result. For example, the server 20 receives and stores the sensing results acquired by the sensing devices of each ship at predetermined time intervals (for example, every minute).

The item "position information" indicates the history of the position information of each ship acquired at the timing of sensing. For example, the server 20 records GPS coordinates consisting of latitude and longitude as position information.

The item "fishfinder image" shows the history of the image acquired by the fishfinder of each ship and displayed on the screen of the fishfinder. On each ship, the result of sensing by the fishfinder is displayed as a real-time image on the screen of the fishfinder. The fishfinder image includes the distribution of the school of fish, the density, the sea level, the topography of the seabed, the water depth, etc., and each is displayed in a different shape, concentration, and color.

The item "sonar image" indicates the history of images acquired by the sonar of each ship and displayed on the sonar screen. On each ship, the result of sonar sensing is displayed as a real-time image on the sonar screen. The sonar image includes an image of a school of fish and an image of the seabed, and each is displayed in a different shape, density, and color.

The item "camera image" shows the history of images taken by the camera of each ship and the state of the ship. On each ship, the camera outputs captured images of the state of the ship in real time.

The position information, the fishfinder image, the sonar image, and the camera image sensed by each ship are sequentially transmitted to the server 20 via the communication with the server 20. While accumulating the above information, the server 20 transmits the accumulated information to the communication terminal 10 in the fleet. As a result, the sensing results sensed at any time on each ship can be shared on each ship in near real time.

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

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

In step S521, the server 20 receives the sensing result acquired by the sensing device of each ship from each ship and stores it in the storage unit. The sensing results referred to here are fishfinder images, sonar images, position information, camera images, etc. acquired by sensing devices such as the fishfinder 11, sonar 12, position information acquisition device 13, and camera 14 mounted on each ship. , Useful information for fishing. The sensing device of each ship (the fish finder 11 or the like) transmits the sensing result 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 a plurality of ships to the communication terminal 10.

In step S511, the communication terminal 10 receives the sensing results of the plurality of ships from the server 20 and displays them on the display. Specifically, the communication terminal 10 senses a nautical chart, an image showing the position of each ship on the nautical chart, and at least a part of each ship in the fleet on the display based on the information received from the server 20. Information to be displayed.

The nautical chart shows the status of the waterways in the area where the fleet is located, that is, the water depth, bottom sediment, coastal topography, and navigation signs. The image showing the position of each ship is, for example, a ship-shaped icon, and presents the position of each ship to the user on a nautical chart. Also, each ship may be displayed in a different image.

Further, the communication terminal 10 divides the display into a plurality of areas so as to display the sensing results of the plurality of ships, and displays the sensing results of each ship in each area. For example, when the fleet is composed of three ships, the display is divided into three rows, and the sensing results for one ship are displayed in each row. 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 receives from the user an operation of designating a ship from each ship displayed on the display. For example, in step S511, the sensing results of the three ships are simultaneously displayed on the display, and in step S512, the communication terminal 10 receives an operation of designating a ship from the three ships from the user.

In step S523, the server 20 transmits the sensing result of the designated ship to the communication terminal 10 in response to the operation of designating the ship. The sensing result of the predetermined ship transmitted by the server 20 in step S523 may be more detailed information than the sensing result of the same ship transmitted in step S523, or may be the same information. When the same information as the sensing result of the same ship transmitted in step S523 is transmitted, step S523 may not be performed.

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

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

According to the above processing, the sensing result of each ship can be shared in real time within the fleet, and only the sensing result of the ship that the user wants to confirm can be displayed. Therefore, it is possible to collect and share the sensing results of each ship, provide useful information for the judgment of the fishing ground, and support the operation of the fleet.

<4 screen example>
6 and 7 are diagrams showing screen examples of the communication terminal 10 according to the first embodiment of the present disclosure. In the following screen example, the sensing results are the fishfinder image, sonar image, position information and camera acquired by sensing devices such as the fishfinder 11, sonar 12, position information acquisition device 13 and camera 14 mounted on each ship. Includes images.

The screen example (A) of FIG. 6 is a diagram showing a situation in which the sensing results of a plurality of ships are aggregated and displayed on one screen and shared in real time within the fleet.

As shown in the screen example (A), in the user's communication terminal 10, the display screen is divided into a plurality of rows, and information for one ship is displayed in each row. For each ship, the ship name and the sensing result of the ship are displayed. For example, in the screen example (A), the screen of the communication terminal 10 is divided into three rows, and information on the ships "1st circle", "2nd circle", and "3rd circle" is displayed in each row. ing. For example, in the third column, the ship name "third circle", an image showing the position information of the third circle, and a sonar image of the third circle are displayed.

The communication terminal 10 may change the display mode of the screen according to the number of ships constituting the fleet or the designation of the user. For example, the communication terminal 10 may change the number of columns on the screen from three columns to two columns according to the user's setting.

Further, the communication terminal 10 may change the type of sensing result displayed on the screen according to the user's designation. For example, according to the user's specification, the fishfinder image and sonar image for the ship "1st circle" are displayed in the 1st column, and the position information and sonar image for the ship "3rd circle" are displayed in the 3rd column. ing.

Further, by designating a predetermined ship in advance, the communication terminal 10 displays the designated ship so as to be different from another ship. For example, as shown in the screen example (A), when the user specifies the ship "third circle" in advance and a plurality of ships are displayed on the display, the ship "third circle" is marked with a star. Display so that it is easier to identify than another ship.

As a result, the sensing results of each ship constituting the fleet can be efficiently shared in real time within the fleet. In addition, information that has been roughly grasped by wireless communication, such as fishfinder images, sonar images, position information, and camera images, can be visually observed in real time.

Therefore, the data sensed by a plurality of ships in the fleet can be aggregated on one screen and shared in real time so that the data can be understood at a glance. Therefore, it is possible to eliminate the communication failure during purse seine / purse seine fishing and facilitate the judgment and operation of the fishing ground.

The screen example (B) of FIG. 6 is a diagram showing a phase of displaying the sensing result of the designated ship. The sensing results of a plurality of ships are displayed at the same time on the display in the screen example (A), and when any ship is specified from these ships, the screen transitions to the screen example (B).

As shown in the screen example (B), the sensing result for one designated ship is displayed on the user's communication terminal 10. For example, when the user wants to check the screen of the fish finder of the search ship (first circle), if the first circle is specified in the screen example (A), the fleet is displayed on the left half of the screen of the surface example (B). The current position of each ship is displayed on the nautical chart, and the sonar image and fishfinder image of the first circle are displayed in real time on the right half. In addition, the communication terminal 10 may highlight the position of the designated ship on the nautical chart.

As a result, only the sensing result of the ship that the user wants to display can be displayed in detail on the display, and the sensing result can be shared so that the user can easily see it.

The screen example (A) of FIG. 7 is a diagram showing a phase of displaying the track of each ship in a predetermined time zone according to the position information acquired by each ship. The start point and the end point of the predetermined time zone referred to here may be preset times (for example, departure time or current time), or may be arbitrary times specified by the user.

For example, as shown in the screen example (A) of FIG. 7, the position of the current time of each ship and the track in the past 3 hours from the current time are displayed on the nautical chart on the display of the communication terminal 10. In addition, the longitude and latitude coordinates of the current time of each ship are displayed.

As a result, the real-time position of each ship in the fleet can be shared, and the route taken during the operation can be shared and recorded. In addition, by visualizing the position and wake of each ship, it is possible to visually check the information roughly grasped by wireless communication in real time. Then, since the route of each ship is continuously recorded on the map, it is possible to avoid re-searching the points where other ships have already passed.

Further, the following information is further displayed on the screen example (A) of FIG. 7.
(I) The communication terminal 10 receives from the user an operation of designating a predetermined point on the wake of each ship, and displays information sensed by the ship at a time corresponding to the point. For example, as shown in the screen example (A) of FIG. 7, in response to an operation in which the user specifies a predetermined point B1 on the track, the server 20 collates the sensing result database 282 with the position of the point B1. By associating the information with the information sensed by the ship that has passed the point B1, the time when the ship passed the point B1 and the fishfinder image, sonar image, camera image, and the like at that time are displayed to the user.

As a result, it is possible to confirm the information sensed at any point on the wake and provide useful information for the operation while utilizing the record of the sensing result.

(Ii) The communication terminal 10 highlights the point by receiving an operation for designating a predetermined point on the nautical chart from the user, and displays the point in association with the information sensed by each ship. For example, as shown in the screen example (A) of FIG. 7, when the user specifies B2, which is a known fishing ground, the point B2 is marked with a star so that it can be easily identified, and the track of each ship is displayed. Display in association with.

As a result, the point to be confirmed can be registered in advance, the point and the information sensed when each ship is operating in the vicinity of the point can be displayed, and the recording of the sensing result can be utilized.

As a result, it is possible to check the track of the past arbitrary time zone and look back on the information of the past operation while utilizing the record of the sensing result.

The screen example (B) of FIG. 7 is a diagram showing a phase of creating a catch record of a predetermined ship.

As shown in the screen example (B) of FIG. 7, the communication terminal 10 receives an operation for creating a catch record for a predetermined ship from the user, thereby associating the catch record with the sensing result of the ship. Record and display information about the catch. For example, in the screen example (B), the user inputs to the communication terminal 10 as a catch record that the catch was made at the point C1. At this time, the communication terminal 10 attaches a fish mark to the point C1 and displays it so that it can be easily identified from another point.

The information that the user inputs when creating a catch record includes, for example, information such as ship name, time of catch, type of catch, weight, quantity (animal), unit price, fishing gear, and the like. By collating the ship name and the fishing time with the sensing result database 282, the server 20 associates the fishing point with the fishing point and automatically associates the fishing point with the fishing result database 282. The user may also directly enter the point of catch as part of the catch record.

As a result, the result of fishing can be easily recorded, and the catch amount and the sensing result of each operation day can be associated and saved, and can be reviewed at any time.

Further, the communication terminal 10 may display the track in the past predetermined time zone from the time when the catch is recorded on the nautical chart so as to be different from another track. For example, as shown in the screen example (B) of FIG. 7, the track between the point C1 where the catch was recorded and the point C2 for the past 1 hour from the time when the catch was recorded is colored with a predetermined color. Display differently from other tracks.

This makes it possible to easily confirm the wake of the ship until it is caught and record it as useful information for future operations.

<3 operation>
Hereinafter, with reference to FIGS. 10, 11 and 12, a process of providing a specific function requested by the user based on the sensing result stored in the server by the fleet operation support system 1 will be described. Here, the specific functions are (i) functions for reducing the risk of operating the ship, (ii) functions for assisting the maneuvering of the fleet, or (iii) management of the method of catching the catch. It is a function for either catch control or distribution control.

<Example 1>
FIG. 10 is a flowchart showing an example of a processing flow that provides a function for managing the risk of the hull as a function for reducing the risk related to the operation of the ship.

In step S1021, the server 20B receives the sensing result acquired by the sensing device of each ship from each ship and stores it in the storage unit 202B. The sensing results here are fishfinder images, sonar images, and position information acquired by sensing devices such as fishfinders, sonar, position information acquisition devices, cameras, exhaust gas temperature gauges, and anemometers mounted on each ship. , Camera image, exhaust temperature, wind direction and speed, etc., which is useful information for fishing. The sensing device of each ship transmits the sensing result to the server 20B by communicating with the server 20B.

In step S1011, the communication terminal 10 receives a request from the user regarding the 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 accepts the request and provides a function for managing the risk of the hull. Send a request to server 20B to provide.

In step S1022, the server 20B manages the hull risk from the sensing result accumulated in the storage unit 202B after receiving the request related to the function for managing the hull risk from the communication terminal 10. The sensing results related to are extracted and processed.

For example, as a risk to the hull, an abnormality may occur in the hull. The server 20B extracts the exhaust temperature of each ship as a parameter related to the abnormality detection of the hull and compares it with a preset threshold value. That is, when the exhaust temperature of the ship is different from the assumed temperature, the server 20B determines that some abnormality has occurred in the hull or each device mounted on the ship. When the exhaust temperature of each ship stored in the storage unit 202B exceeds the threshold value, the server 20B collates the sensing result database 282B and identifies the ship in which the abnormality has occurred. Alternatively, the server 20B extracts the exhaust temperature as an abnormality detection parameter, and calculates the degree of deviation of the exhaust temperature of each ship stored in the storage unit 202B from a preset normal value by a machine learning method. May be good.

In step S1023, the server 20B transmits the result of abnormality detection to the communication terminal 10 based on the related sensing result. For example, in step S1022, when the server 20B determines that the exhaust temperature exceeds the threshold value and an abnormality has occurred based on the exhaust temperature stored in the storage unit 202B, the server 20B determines that the abnormality detection result is obtained in each of the fleets. It is transmitted to the communication terminal 10. Further, the server 20B may 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 abnormality detection from the server 20B.

Through the above series of processes, the process of providing the function for managing the risk of the hull is completed based on the sensing result accumulated in the server.

Here, the server 20B may refer to another parameter sensed by each ship in order to detect that an abnormality has occurred in the hull. For example, the server 20B may detect that an abnormality has occurred in each ship based on the parameter of the drainage temperature of the ship. For example, when the drainage temperature is abnormally high or extremely low compared to the temperature assumed when operating the hull, some abnormality has occurred in the hull (for example, a predetermined value mounted on the hull). Detects that the device is not operating normally). That is, the server 20B detects that an abnormality has occurred in the hull by comparing the drainage temperature with a preset threshold value.

Further, the server 20B may detect that an abnormality has occurred in each ship based on the operating time of each device of the hull and the operating sound generated when each device is operating. For example, the server 20B may detect that an abnormality has occurred as a device of the hull based on at least either the operating time of the engine or the operating noise when the engine is operating. The server 20B compares the operating time of the engine (the cumulative operating time of operating the engine, the time of continuously operating the engine, etc.) with the preset threshold value, and an abnormality occurs in the engine. Determine the possibility of doing so. Further, the server 20B determines that an abnormality has occurred in the engine by comparing the sensing result of the operating sound of the engine with the operating sound when the engine is operating normally and determining the degree of matching. Detect.

Further, the server 20B may detect that an abnormality has occurred in the hull based on the following sensing results.
・ Flood control ・ Engine speed ・ Battery voltage ・ Fuel level ・ Fish finder and other fishing equipment errors ・ Ship status information (maintenance history, failure rate, etc.)
The server 20B detects that an abnormality has occurred in the hull based on the sensing result of each ship, and notifies the communication terminal 10 of each ship constituting the fleet. For example, in the above example, when the amount of decrease in the remaining fuel amount is larger than expected in the navigation of the fleet, the server 20B may detect that some abnormality has occurred in the hull. This makes it easier for each ship to share that something is wrong with the ships that make up the fleet, and tells the crew of each ship to operate the fleet on the assumption that something is wrong with the hull. Can be prompted.

Further, the server 20B generates smoke by performing image recognition based on a photographed image of the hull (a photographed image of a camera installed on the hull), a photographed image of a device mounted on the hull, and the like. Detects that. The server 20B may detect that an abnormality has occurred in the hull due to the smoke being generated. That is, the server 20B detects that an abnormality has occurred in the hull because the device mounted on the hull is in an abnormal state and smoke is generated.

Further, the server 20B may detect that an abnormality has occurred in the hull by targeting the following as a shooting target based on the shot images taken by each ship.
-Images taken of instruments such as pressure gauges and rotometers A camera (or a communication terminal 10 equipped with a camera) is installed so as to take pictures of these instruments mounted on the hull, and the server 20B uses these cameras. By recognizing the captured image of, the numerical value of the instruments is monitored. When the numerical value of the instrument indicates an abnormal value, the server 20B detects an abnormality in the hull.

As a result, the result of abnormality detection is displayed and shared in real time on each ship in the fleet according to the user's request. Therefore, according to the user's request, it is possible to detect an abnormality in the hull at an early stage and support the operation of the fleet while utilizing the sensing result.

In FIG. 10, the flow of providing the function for managing the risk of the hull has been described by taking the abnormality detection of the hull as an example, but the function for reducing the risk related to the operation of the ship is not limited to this. Further examples are given below.

<Example 2>
When the risk of ship operation is hull risk management, the information processing device (server 20B) has at least information on the sensing results sensed by each ship, information on the performance of each ship, and information on the operation results of each ship. Based on either, the ship insurance to be provided to each ship is specified, and the ship insurance information is transmitted to the user's terminal.

For example, when the server 20B determines that the exhaust temperature stored in the storage unit 202B exceeds the threshold value and an abnormality has occurred, the server 20B identifies the ship in which the abnormality has occurred, and information on the performance of the ship or information on the operation record. Based on, identify the ship insurance that covers the damage that can occur due to the abnormality, and send the ship insurance information to the terminal of the ship.

Thereby, according to the user's request, it is possible to present appropriate ship insurance information to each ship while utilizing the sensing result.

Further, when the risk related to the operation of the ship is the risk management of the hull, the server 20B detects that each ship collides with some object and notifies the communication terminal 10 or the like. For example, based on a camera, an acceleration sensor, or the like mounted on each ship, the server 20B detects that the ship collides with another ship and moves differently from normal navigation. Each ship may collide with another ship or land. Also, each ship may be stranded. In addition, each ship may collide with objects (floating matter, etc.) floating on or under the sea such as driftwood, ice blocks, buoys, and fixed nets. The server 20B detects that each ship has collided based on a camera, an acceleration sensor, a position information sensor, or the like mounted on each ship.

Further, in order to manage the risk of the hull, the server 20B detects that each ship is capsized or is about to capsize based on the sensing result of each ship and notifies the communication terminal 10 or the like. .. For example, the server 20B detects that the ship is tilted beyond normal navigation based on the output of an acceleration sensor or the like mounted on the ship.

Further, the server 20B determines the possibility that the fishing net may be damaged when the fishing net is sown as a risk related to the operation of the ship, and notifies the communication terminal 10 or the like of the determination result. Depending on the sea area, fishing nets may be damaged when they are sown. For example, there is an artificial object such as a sunken ship on the seabed, and the contact between the artificial object and the fishing net may damage the fishing net. The server 20B updates the seafloor map based on the sensing result of each ship, and based on the seafloor map (for example, due to the presence of an artificial object such as a sunken ship on the seabed), the fishing net is damaged when it comes into contact with the fishing net. Judge the possibility for each sea area. As a result, the server 20B notifies the communication terminal 10, for example, of the sea area where each ship is located (or the sea area near each ship) where it is not preferable to sew a fishing net.

Further, the server 20B determines the timing of whether or not each ship catches fish based on the sea condition information (wave height, sea wind, tidal current, etc.), and notifies the determination result to the communication terminal 10 or the like. May be good. For example, based on the prediction result of the wave height in a certain fishing ground, it is difficult to safely navigate each ship in the sea area at the timing when the risk of fishing is high, so it is better not to fish. Is determined.

In addition, if the mesh of the fishing net is too small for the size and amount of fish caught in the sea area, a large amount of fish will be caught in the fishing net, and the fishing net may be damaged. That is, the server 20B can evaluate the possibility that the fishing net will break when the fishing net is sown in the sea area by comparing the evaluation parameters based on the size of the fish and the amount of the fish with the threshold value. The server 20B predicts the size and amount of fish caught in each sea area based on the sensing result of each ship (for example, information on the past fishing results in each sea area). Based on the prediction result, the server 20B notifies the communication terminal 10 of the information on the sea area where the fishing net may be sown and the information on the sea area where the fishing net may be damaged when the fishing net is sown. can do.

<Example 3>
When the risk involved in the operation of a ship is the risk management of seafarers, the information processing device (server 20B) provides at least one of the functions of managing the health of the seafarers of each ship and the function of managing labor to the user's terminal. offer. The information processing device (server 20B) stores at least the images taken by the camera that captures the onboard of each ship as the sensing result of each ship in the storage unit 202B, and based on the captured images, the sailors of each ship It identifies the state of health and labor, and sends the identified result to the user's terminal. It also identifies the state of labor based on whether the movement of seafarers on board is a predetermined act.

For example, when the server 20B receives a request related to a seafarer's risk management function from the communication terminal 10, the server 20B extracts an image taken by a camera that captures the onboard of each ship from the sensing results stored in the storage unit 202B. Then, the movement of each seafarer is analyzed by the machine learning method, and the health condition and labor condition of each seafarer are specified. For example, to generate a trained model based on the image taken by the camera when the sailor's health condition and labor condition are deteriorating (or the image taken by the camera when the sailor's health condition and labor condition are good). Therefore, it is possible to evaluate whether or not the health condition and labor condition of the sailors are appropriate based on the images taken by the cameras of each ship and the trained model. Further, for example, an image taken by a camera is extracted and analyzed, and it is determined whether or not the movement of each sailor is appropriate at the time of winding up the net. The server 20B transmits the analysis and the specific result to the communication terminal 10 and displays them.

Here, the server 20B may determine whether or not the degree of fatigue of the seafarer exceeds a certain level as the health state and labor state of the seafarer, and notify the communication terminal 10 or the like of the determination result. For example, a server that senses the movement of a seafarer in a state where fatigue is not accumulated in the seafarer (camera image, etc.) and the movement of a seafarer in a state where the degree of fatigue is high in the seafarer. By holding on to 20B (by generating a trained model based on this information), the server 20B may be able to assess the degree of seafarer fatigue based on the sensing results of each ship.

Similarly, the server 20B may determine whether or not the occupant is ill and notify the communication terminal 10 or the like of the determination result.

Further, the server 20B may detect the occurrence of an occupational accident as the labor state of the seafarer and notify the communication terminal 10 or the like of the detection result. Serious occupational accidents include the sailors falling from the ship into the sea (falling) and the sailors getting caught in fishing nets. The server 20B detects the sailors based on the sensing results such as the images taken by the cameras of each ship, detects that the sailors have fallen into the sea, and that the sailors are caught in the fishing net, and transmits the detection results to the communication terminal. Notify 10 mag.

As a result, it is possible to grasp the health status and labor status of the seafarers of each ship and manage the risks of the seafarers while utilizing the sensing results according to the user's request.

In addition to these, the server 20B may manage the state of the sailors of each ship based on the following information.
-Personnel utilization rate-Personnel salary For example, the server 20B can specify the crew utilization rate based on the number of days the crew is fishing.

<Example 4>
FIG. 11 is an example flowchart that provides a function for supporting the maneuvering of the fleet. In this example, the function for assisting the maneuvering of the fleet is the function for automatically navigating the ship.

In step S1121, the server 20B receives the sensing result acquired by the sensing device of each ship from each ship and stores it in the storage unit 202B. The sensing results here are fishfinder images, sonar images, and position information acquired by sensing devices such as fishfinders, sonar, position information acquisition devices, cameras, exhaust gas temperature gauges, and anemometers mounted on each ship. , Camera image, exhaust temperature, wind direction and speed, etc., which is useful information for fishing. The sensing device of each ship transmits the sensing result to the server 20B by communicating with the server 20B.

In step S1111, the communication terminal 10 receives a request from the user regarding the 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 accepts the request and provides a function for automatically navigating the ship. The request is sent to the server 20B.

In step S1122, the server 20B receives a request for the function for automatically navigating the ship from the communication terminal 10, and then automatically navigates the ship from the sensing result stored in the storage unit 202B. The sensing results related to are extracted and processed.

For example, the server 20B extracts the wind speed data, the wind direction data, the ship speed data, the current position information of the ship and the position of the home port from the sensing results stored in the storage unit 202B, and can reduce the fuel consumption optimally. Determine a good route.

In step S1123, the server 20B transmits information for automatically navigating the ship to the communication terminal 10 based on the related sensing result. For example, in step S1122, the server 20B determines the optimum route in which the fuel consumption can be reduced based on the sensing result stored in the storage unit 202B, and in step S1123, the server 20 determines the optimum route. Is generated and transmitted to the communication terminal 10.

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

Through the above series of processes, the process of providing the function for automatically navigating the ship is completed based on the sensing result stored in the server.

As a result, information for automatically navigating the ship is generated in real time and displayed to the user in response to the user's request. Therefore, according to the user's request, it is possible to provide information for automatically navigating the ship while utilizing the sensing result.

In FIG. 11, the flow of providing the function for supporting the maneuvering of the fleet has been described by taking as an example the automatic navigation of the ship, but the function for supporting the maneuvering of the fleet is not limited to this, and the following Further processing is mentioned.

<Example 5>
The function to support the maneuvering of the fleet is to provide at least one of the nautical chart and the seabed map, and the information processing device (server 20B) is based on the sensing result sensed by each ship, and the nautical chart and the seabed are used. At least one of the maps is updated, and at least one of the updated nautical chart and the seabed map is transmitted to the user's terminal (communication terminal 10).

For example, the server 20B updates the seabed map by extracting data on the state of the seabed based on the fishfinder image and the sonar image stored in the storage unit 202B, and transmits the updated seabed map to the communication terminal 10. do. Alternatively, the server 20B updates the nautical chart by extracting data related to the nautical chart based on the past track of the ship, and transmits the updated nautical chart to the communication terminal 10.

Thereby, according to the user's request, it is possible to provide a nautical chart or a seafloor map while utilizing the sensing result. Here, since the server 20B updates the nautical chart and the seabed map based on the results sensed at each ship at any time, it is possible to provide the communication terminal 10 with the nautical chart and the seabed map based on the latest sensing result.

In addition to the above examples, as a function to support the maneuvering of the fleet, the server 20B uses the fuel consumption of the fleet based on information such as the tidal current and wind speed in the sea area (that is, the cost factor of the fuel cost for navigating the fleet). ), Predicting the catch in the sea area, and communicating the navigation method of the fleet (navigation route, navigation speed, etc.) of the fleet based on the information of other fleets fishing in the sea area. It may be notified to the terminal 10 or the like. For example, if there are multiple competitors fishing in a fishing ground (multiple fleets), the expected catch (eg, competitors) to arrive at the fishing ground earlier than the other fleets for a particular fishing ground. Based on the expected catch if not) and the fuel consumption to arrive at the fishing ground earlier (a large amount of fuel may be consumed by increasing the navigation speed of the fleet). The navigation method may be proposed to the user such as the communication terminal 10. For example, on the communication terminal 10 or the like, the user can display the navigation method including the catch (so-called expected sales) and the fuel consumption (so-called expected cost) on the screen over a plurality of patterns. Suppose that a pattern specification is accepted. In this case, the communication terminal 10 or the like may control the navigation of each ship so as to automatically navigate based on the navigation method received from the user. That is, the server 20B can propose to the fishermen a navigation method that maximizes profits based on catch and fuel consumption.

Further, as a function for supporting 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 or the like. For example, as sea surface information, water temperature information can be referred to in making predictions of fishing grounds. Further, when the server 20B provides tidal current information (tidal current prediction result) to the communication terminal 10 or the like as sea condition information, it is 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 vessel can quickly reach a driving speed that is advantageous for fishing.

<Other examples of functions to assist the fleet's maneuvering>
The server 20B may provide a function of outputting instructions from any of the ships of the fleet to other ships as a function of supporting the maneuvering of the fleet.

Such an instruction content includes transmitting an instruction regarding navigation from any communication terminal 10 of each ship of the fleet to each ship of the fleet. For example, in any of the ships of the fleet, the user navigates the target point (point information), the target route (line information) for navigating the ship, and the ship on the nautical chart. It is assumed that the communication terminal 10 specifies the content of the instruction such as the speed of the operation. The instruction content is transmitted from the communication terminal 10 of the ship to the server 20B, and the server 20B notifies each ship of the fleet. As a result, the contents of instructions from a certain ship are accurately shared by each ship. Each ship may set automatic navigation or the like based on the instruction content received in this way.

Further, such an instruction content includes transmitting an instruction regarding the timing of fishing to each ship from the communication terminal 10 of any of the ships of the fleet. For example, in any of the ships of the fleet, it is assumed that the user specifies the instruction content regarding the fishing timing such as the timing of inserting the net and the timing of pulling up the net on the communication terminal 10. As a result, the content of instructions from a certain ship is shared with each ship, and the timing of introducing these networks is shared by text information, voice, video, and the like.

<Example 6>
FIG. 12 is a flowchart showing a process for providing a method for catching a catch or a function for managing a catch.

In step S1121, the server 20B stores the information on the sea area and the information on the fishing method or the catch amount of a specific fish caught in the sea area in the storage unit 202B based on the result sensed by each ship. The communication terminal 10 receives input of information on the catch (in which sea area, how much catch, etc.) from the user, and transmits the received information on the catch to the server 20B, thereby causing the server. Information on the catch of each sea area may be managed at 20B.

For example, the server 20B catches the catch in one operation based on the position information sensed by each ship, the camera image when winding the net, or the information acquired by the device for measuring the catch. The information on the sea area where the fish was carried out and the information on the fishing method or the catch amount of a specific fish caught in the sea area are accumulated.

In step S1211, the communication terminal 10 receives a request from the user regarding the method for catching the catch or the function for managing the catch. The communication terminal 10 presents a plurality of specific functions to the user, and when the user selects a method for catching the catch or a function for managing the catch, the communication terminal 10 accepts the request and receives the request to obtain the method for catching the catch or the method for catching the catch. A request is sent to the server 20B to provide a function for managing the catch.

In step S1222, the server 20B receives the request related to the fishing method of the catch or the function for managing the catch from the communication terminal 10, and then from the storage unit 202B, the information of the sea area and the identification in the sea area are specified. Information on the method of catching the fish or the amount of catch is extracted and processed.

In step S1123, the server 20B determines whether or not the fishing method or the catch amount in each sea area is appropriate, and transmits the determination result to the user's terminal. The criterion for determination may be, for example, a fishery resource management measure in the sea area where the fish was caught.

In step S1112, the communication terminal 10 receives and displays a determination result as to whether or not the fishing method in each sea area is appropriate from the server 20B.

Further, the control unit 203B of the server 20B may authenticate that the fishing method or the catch amount in each sea area is appropriate based on the determination result. For example, the server 20B manages the information on the fishing method and the catch amount permitted in each sea area in the storage unit 202B, and the catch method and the catch amount of the ship are appropriate based on the sensing result of each ship. Determine if it exists (remains within the allowed range). In addition to the appropriate catch, the server 20B should certify the catch (MSC (registered trademark): Marine Stewardship Council certification, fishery ecolabel, marine ecolabel (registered trademark) certification, etc.). May be. The server 20B may authenticate that the catch is legitimately caught in each sea area, and may provide the user with a function for performing these authentications and a consulting service for obtaining the certification. .. For example, the server 20B may authenticate the catch based on the photographed image of the catch.

The above series of processes completes the process of providing a function for managing the method of catching the catch or the catch.

As a result, the determination result as to whether or not the fishing method or the catch amount in each sea area is appropriate is displayed to the user according to the request of the user. Therefore, according to the user's request, it is possible to manage the fishing method or the catch amount of the catch while utilizing the sensing result.

FIG. 11 describes the method of catching the catch or the flow of managing the catch, but the present invention is not limited to this, and the following processing can be further mentioned.

<Example 7>
When a specific function is a function for managing the distribution of catch, the information processing device (server 20B) stores information on the catch of each ship in the storage unit 202B, and causes the user's terminal to display each fishing port. Provides information on catches in association with. The control unit 203B of the server 20B provides the user's terminal (for example, the terminal of the user who purchases fish) with information on the type and amount of fish caught as information on the catch, and the user's terminal provides the information. Accepts operations to buy fish.

For example, the server 20B stores the information on the catch of each ship in the storage unit 202B, and transmits the information on the catch to each fishing port. The user of each fishing port uses the communication terminal 10 to input an operation for purchasing the catch by auction.

Thereby, according to the user's request, it is possible to facilitate the distribution of the catch while utilizing the sensing result. That is, since the catch information is provided to the server 20B from each ship, it is possible to accept the operation for purchasing the fish from the user's terminal, so that each ship is on the way back to the port (that is, each ship). It will be possible to purchase fish before the fish on the ship arrive at the fishing port). Here, the server 20B may notify the information of the fish to the terminals of a plurality of users. At each user's terminal, the user accepts the designation of the amount of money for auctioning off the fish. This allows the fish to be auctioned before it enters the fishing port. Therefore, it is possible to shorten the period for delivering the fish from each ship to the user who purchases the fish. In addition, the server 20B thus obtains information on the fish caught by each ship, information on the fisherman who caught the fish, information on the purchaser who purchased the fish, and the purchased fish by secondary distribution. It may be possible to manage the information of the vendor. For example, the server 20B may record the information of each distributor in the process until the consumer consumes the fish caught by the fisherman and manage it by the blockchain technology. The server 20B prepares an environment for each distributor to purchase fish (for example, a screen for purchasing fish), so that the fish caught by the fisherman can be used as a secondary distributor. It is possible to control whether the fish has been delivered to the final consumer, and it is possible to provide the final consumer with traceability of which fisherman caught the fish.
