[Technical Field]

[0001] The present disclosure relates to an information sharing device, an information sharing method, and a program. [Background technology]

[0002] With the widespread use of unmanned aerial vehicles (hereinafter referred to as unmanned aircraft) such as drones, there is a movement to utilize unmanned aircraft for inspections at designated facilities such as airports. At such designated facilities, it is expected that only authorized drones (permitted aircraft) will be operated. However, as the use of unmanned aircraft at designated facilities becomes widespread, there is a risk that unauthorized drones (suspicious aircraft) will infiltrate the designated facilities. Therefore, it is necessary to distinguish between authorized and suspicious drones both inside and outside designated facilities.

[0003] Patent Document 1 discloses a drone control device that aims to comprehensively manage drones in flight. The device in Patent Document 1 receives status information, including the drone's identification information and current location, from drones flying in the airspace to be managed. The device in Patent Document 1 monitors the drone's status based on the received status information and detects drones to be controlled. The device in Patent Document 1 then transmits control instructions to the detected drones. [Prior art documents] [Patent documents]

[0005] The method of Patent Document 1 generates evacuation instructions and warning information for drones that exist in or invade airspace that affects the flight of manned aircraft. Furthermore, the method of Patent Document 1 also notifies the air traffic control system that a drone is flying in airspace that affects the flight of manned aircraft. However, the method of Patent Document 1 does not share information about drones in managed airspace with the relevant departments that manage the operation of managed facilities. If information about drones in managed airspace differs among the relevant departments, there is a risk that an airport may not be able to operate properly. Furthermore, there may be situations where the relevant departments do not have information about drones in managed airspace.

[0006] The purpose of the present disclosure is to provide an information sharing device, an information sharing method, and a program that enable multiple related departments that manage the operation of managed facilities to share information about drones in managed airspace. [Means for solving the problem]

[0008] In one aspect of the information sharing method of the present disclosure, drone information regarding drones detected in a managed airspace including above and around a managed facility is collected, and a computer uses the collected drone information to determine whether the drone detected in the managed airspace is an authorized drone or a suspicious drone, and transmits information indicating whether the drone detected in the managed airspace is an authorized drone or a suspicious drone to devices used in multiple relevant departments that manage the managed facility.

[0009] A program of one embodiment of the present disclosure causes a computer to perform the following processes: collect drone information regarding drones detected in a managed airspace, including above and around a managed facility; use the collected drone information to determine whether the drone detected in the managed airspace is an authorized drone or a suspicious drone; and transmit information indicating whether the drone detected in the managed airspace is an authorized drone or a suspicious drone to equipment used in multiple relevant departments that manage the managed facility.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Below, embodiments for implementing the present disclosure will be described using the drawings. In this disclosure, the drawings used in the description of each embodiment relate to one or more embodiments. Furthermore, elements included in each drawing may apply to one or more embodiments. The embodiments described below are limited in a way that is technically preferable for implementing the present disclosure, but this does not limit the scope of the disclosure to the following. In all drawings used to describe the following embodiments, similar parts are designated by the same reference numerals unless otherwise specified. In the following embodiments, repeated description of similar configurations and operations may be omitted. The direction of arrows in the drawings is an example and does not limit the direction of signals, data, etc.

[0013] (First embodiment) First, an information sharing device according to a first embodiment will be described with reference to the drawings. The information sharing device according to this embodiment functions as an information sharing platform for sharing information related to the operation of unmanned aerial vehicles among relevant departments that manage the operation of managed facilities. For example, unmanned aerial vehicles are multicopter, helicopter, or airplane-type drones. Hereinafter, unmanned aerial vehicles will be referred to as unmanned aircraft. Unmanned aircraft may be those that travel on land or navigate on or underwater. Furthermore, unmanned aircraft may be flying cars that can accommodate people.

[0014] In this embodiment, an airport is assumed as a facility to be managed. In this embodiment, an example of sharing information about drones flying in the airspace inside and around the airport (managed airspace) will be described. The inside of an airport can also be expressed as above the airport. The facility to be managed is not limited to an airport, as long as the inside and outside can be distinguished. For example, the facility to be managed may be a public facility that the general public can enter and exit, such as a train station, a port, a stadium, or a park. For example, the facility to be managed may be a facility that only a limited number of people can enter, such as a power plant, a factory, a school, a hospital, a prison, or a military base.

[0015] (composition) 1 is a conceptual diagram illustrating an example of a system for managing a facility to be managed in the present disclosure. In this embodiment, the facility to be managed is equipped with a monitoring system 110, a flight support system 120, and an air traffic control system 130. The facility to be managed may be equipped with systems other than the monitoring system 110, the flight support system 120, and the air traffic control system 130.

[0016] The monitoring system 110, the flight operation support system 120, and the air traffic control system 130 are connected to the information sharing device 10 via a network such as the Internet or an intranet. Drone information collected by each of the monitoring system 110, the flight operation support system 120, and the air traffic control system 130 is provided to the information sharing device 10. The drone information provided to the information sharing device 10 is shared with multiple related departments that manage the facilities to be managed via the monitoring system 110, the flight operation support system 120, and the air traffic control system 130.

[0017] The monitoring system 110 is a system for monitoring drones entering the airport from the airport periphery. For example, the monitoring system 110 is used by security personnel who provide airport security. The monitoring system 110 detects drones using electromagnetic waves of a predetermined wavelength. For example, the monitoring area of ​​the monitoring system 110 is the airspace around the airport. The monitoring area of ​​the monitoring system 110 may also include the airspace inside the airport. The airspace around the airport is restricted by aviation law from the installation of buildings, plants, and other objects to ensure safe takeoff and landing of aircraft. Each airport has a restricted surface that defines the boundary of the area around the airport where buildings, plants, and other objects cannot be installed. For example, the monitoring system 110 may be configured to detect only drones flying above the restricted surface. This configuration reduces the number of drones to be detected, thereby reducing the processing load of the information sharing device 10, but there is a possibility that a drone entering beyond the restricted surface may be overlooked. Therefore, the monitoring system 110 preferably detects drones flying around the airport regardless of the restricted surface. For example, the monitoring system 110 may be configured to monitor the installation of illegal objects beyond the restricted surface.

[0018] For example, the monitoring system 110 is configured to detect drones using radar (radio detecting and ranging). For example, the radar is placed at the boundary between the interior and periphery of an airport. Radar is a device that measures the distance to and direction of a target by reflecting radio waves emitted from a source. The radar's detection range is several kilometers from the source. For example, the monitoring system 110 is configured to detect drones using radar that transmits and receives microwaves or millimeter waves. The monitoring system 110 may use a single radar or multiple radars. The radar changes the radiation direction of the radio waves to scan the managed airspace. If the managed airspace is large, it takes a long time to scan the entire managed airspace, which may result in the drones flying in the managed airspace being missed. Therefore, it is preferable that the monitoring system 110 monitors the managed airspace using multiple radars in cooperation with each other. The frequency band and radiation power of the radio waves used by the radar vary depending on the application. It is preferable that the radio waves used by the radar be in a frequency band that does not interfere with the radio waves used by other systems. If the managed airspace is an airport, it is difficult to install a new radar to avoid interference with the radio waves of existing radar. In such cases, the surveillance system 110 may be configured to detect drones using existing radar. For example, existing radars include air traffic control radar, marine radar, and weather radar.

[0019] For example, the monitoring system 110 is configured to detect drones using a passive radar. Passive radar is also called a radio wave detection sensor. For example, the passive radar is placed at the boundary between the interior and perimeter of an airport. The passive radar is a sensor that detects radio waves used for communication between a flight control device that controls the flight of the drone and the drone being controlled. The detection range of the passive radar is approximately 1 kilometer from the center of the wave source. The monitoring system 110 detects radio waves transmitted from the flight control device to the drone and from the drone to the flight control device. For example, the monitoring system 110 is configured to detect drones using radio waves in a frequency band permitted for use in controlling drones. The monitoring system 110 identifies the location of the drone based on a sensor signal output from the passive radar. The monitoring system 110 may use a single passive radar or multiple passive radars. To cover the entire managed airspace, multiple passive radars are preferably used.

[0020] For example, the monitoring system 110 is configured to detect drones using a LiDAR (Light Detection and Ranging). For example, the LiDAR is placed at the boundary between the interior and perimeter of an airport. For example, the monitoring system 110 is configured to detect drones using a LiDAR that transmits and receives electromagnetic waves in the ultraviolet, visible, and near-infrared regions. The detection range of a LiDAR is several hundred meters from the center of the wave source. LiDAR is used in the field of meteorology to detect air currents such as turbulence. Therefore, the monitoring system 110 may be configured to detect drones by detecting air currents generated by the flight of the drone. The monitoring system 110 may use a single LiDAR or multiple LiDARs. To cover the entire managed airspace, multiple LiDARs are preferably used.

[0021] For example, the surveillance system 110 is configured to detect drones using a camera. For example, the camera is placed at the boundary between the airport's interior and perimeter. For example, the camera is used to classify targets detected by radar or other devices. Targets can also be tracked using the images captured by the camera. For example, the camera is sensitive to electromagnetic waves in the visible, near-infrared, and infrared regions. The camera captures images of the managed airspace and outputs the captured images as sensor signals. The surveillance system 110 detects drones from the captured images by processing the images output from the camera using object recognition processing. The surveillance system 110 may use a single camera or multiple cameras. To cover the entire managed airspace, multiple cameras are preferably used. For example, information indicating the camera's pointing direction is reflected on a map in real time. For example, in the case of multiple cameras, information indicating which camera is tracking which target in the image is overlaid on the map. For example, the surveillance system 110 detects drones from images captured by a fixed camera. The monitoring system 110 may be configured to detect drones from images captured by a portable camera. For example, the portable camera is a camera incorporated into a mobile device such as a wearable terminal, smartphone, or tablet. In this case, the monitoring system 110 may be configured to acquire images and videos captured by the camera via wireless communication with the mobile device.

[0022] The flight operation support system 120 is a system for supporting the operation of drones working inside an airport. For example, the flight operation support system 120 is used by an inspector who performs inspections inside the airport. The flight operation support system 120 manages flight plans for performing inspections using drones inside the airport. Flight plans for drones inside the airport are registered in advance in the flight operation support system 120. The flight plans for drones may be configured to be generated by the flight operation support system 120. The flight plans managed by the flight operation support system 120 are provided to the information sharing device 10.

[0023] The air traffic control system 130 is a system for controlling aircraft taking off and landing at an airport. For example, the air traffic control system 130 manages aircraft flight plans and change information, displays aircraft position information, and the like. For example, the flight operation support system 120 is used by air traffic controllers who control air traffic. The air traffic control system 130 is used for communication between aircraft pilots and air traffic controllers. For example, the information sharing device 10 may be configured to share information, including the content of communication between aircraft pilots and air traffic controllers, with related departments.

[0024] 2 is a block diagram showing an example of the configuration of an information sharing device according to the present disclosure. Information sharing device 10 includes an information collection unit 11, a plan acquisition unit 12, a determination unit 13, and an information sharing unit 15. For example, information sharing device 10 is implemented in a server or computer located inside a facility to be managed. Information sharing device 10 may also be implemented in a server located in a data center outside the facility to be managed, or in the cloud.

[0025] The information collection unit 11 collects information (drone information) about drones flying in the managed airspace. The information collection unit 11 collects drone information about drones detected by the monitoring system 110. The drone information includes location information for each of multiple drones flying in the managed airspace. For example, the location information is measured using images or videos captured in the managed airspace. For example, the location information may be extracted from transmitted information transmitted from a device such as a remote ID mounted on the drone. The drone information also includes identification information for each of multiple drones flying in the managed airspace. For example, the identification information includes an identifier (ID) for uniquely identifying the drone. For example, the identification information is included in transmitted information transmitted from a device such as a remote ID mounted on the drone. For example, the information collection unit 11 may be configured to collect control signals used to control the drone.

[0026] FIG. 3 is a table showing an example of identification information collected by an information sharing device according to the present disclosure. The identification information 111 includes a drone ID, location information, and time information. The drone ID is an identifier for uniquely identifying the drone. The location information indicates the location of the point where the identification information is transmitted. For example, the location information is measured by a GPS (Global Positioning System) function installed in the drone. The time information is measured by a clock function installed in the drone.

[0027] The plan acquisition unit 12 acquires a flight plan for the drone in the managed airspace. The flight plan includes a plan for the flight of the drone inside and around the airport, which corresponds to the managed airspace. The flight plan for the drone around the airport is acquired from a drone traffic control system (not shown) operated by a national or local government. For example, the traffic control system used within the airport may be configured to acquire information from a traffic control system used outside the airport using an information linkage function. The flight plan for the drone inside the airport is acquired from a traffic support system 120 that manages the operation of inspection drones inside the airport.

[0028] The plan acquisition unit 12 acquires a flight plan including a plan to fly in the permitted airspace around the airport at the current time. For example, the plan acquisition unit 12 may be configured to acquire a flight plan including a plan to fly in the permitted airspace around the airport for a time period (e.g., 10 minutes) that includes the current time. The plan acquisition unit 12 also acquires a flight plan including a plan to inspect the interior of the airport at the current time. The inspection of the interior of the airport is performed using a camera, communication equipment, etc. mounted on the drone. For example, the plan acquisition unit 12 is configured to acquire a flight plan including a plan to inspect the interior of the airport for a time period (e.g., 10 minutes) that includes the current time. The plan acquisition unit 12 may also be configured to acquire a flight plan including the drone ID of a drone detected in the managed airspace.

[0029] FIG. 4 is a table showing an example of a flight plan acquired by an information sharing device according to the present disclosure. FIG. 4 shows a flight plan including a plan for flying around an airport. The flight plan 121 includes a flight plan ID, a drone ID, a departure point, a scheduled departure time, a destination, and a scheduled arrival time. The flight plan ID is an identifier for uniquely identifying the flight plan. The drone ID is an identifier for uniquely identifying the drone. The departure point indicates the location of the point from which the drone departs. The scheduled departure time indicates the scheduled time at which the drone departs. The destination indicates the location of the destination of the drone. The scheduled arrival time indicates the scheduled time at which the drone arrives at the destination.

[0030] FIG. 5 is a table showing an example of a flight plan acquired by an information sharing device according to the present disclosure. FIG. 5 shows a flight plan including a plan to inspect the interior of an airport. The flight plan 122 includes a flight plan ID, a drone ID, an inspection point, a scheduled start time, and a scheduled end time. The flight plan ID is an identifier for uniquely identifying the flight plan. The drone ID is an identifier for uniquely identifying the drone. The inspection point indicates the facility or area to be inspected. The inspection point may be specified by location information. The scheduled departure time indicates the scheduled time for the drone to start the inspection. The scheduled end time indicates the scheduled time for the drone to end the inspection.

[0031] The determination unit 13 acquires the drone information collected by the information collection unit 11. The determination unit 13 also acquires the flight plan acquired by the plan acquisition unit 12. The determination unit 13 refers to the flight plan to determine whether the drone included in the drone information is an authorized drone or a suspicious drone. A drone that is authorized to operate around or inside the airport during a time period that includes the target time is registered in a flight plan that includes the target time. In other words, a drone registered in a flight plan that includes the target time is an authorized drone. On the other hand, a drone that is not registered in a flight plan that includes the target time is a suspicious drone. The determination unit 13 outputs information including a determination result indicating whether the drone is an authorized drone or a suspicious drone for each detected drone to the information sharing unit 15.

[0032] The information sharing unit 15 distributes information including the determination result by the determination unit 13 to relevant departments that operate the airport, which is a facility to be managed. In this embodiment, the information sharing unit 15 distributes the shared information to the monitoring system 110, the flight operations support system 120, and the air traffic control system 130. The shared information distributed to the monitoring system 110, the flight operations support system 120, and the air traffic control system 130 is shared among personnel using these systems. For example, the information sharing unit 15 may be configured to provide the shared information in a format via a standardized interface based on the System Wide Information Management (SWIM). Using the System Wide Information Management (SWIM) as a base allows SWIM managers, service providers, and service users to share information via the systems and devices they use.

[0033] The information sharing device 10 is connected to a monitoring system 110, a flight operations support system 120, and an air traffic control system 130 via a network. For example, the monitoring system 110, the flight operations support system 120, and the air traffic control system 130 are constructed on a cloud or a server connected to the information sharing device 10 via a network. The monitoring system 110, the flight operations support system 120, and the air traffic control system 130 may be implemented on a server or a server located within an airport. The information shared by the monitoring system 110, the flight operations support system 120, and the air traffic control system 130 is referenced by personnel using these systems. The information sharing device 10 may also be configured to provide the shared information to related organizations other than the relevant departments that operate the airport. For example, the information sharing device 10 may be configured to provide the shared information to related organizations such as airport operating companies, police, airlines, and insurance companies. The shared information provided to the related organizations may include information customized for each related organization.

In the shared information of FIG. 12, the airspace in which the drone was detected is represented by a cube. Representing the airspace in which the drone was detected three-dimensionally allows the location of the airspace to be intuitively understood. For example, a three-dimensional grid or three-dimensional information including the airspace in which the drone was detected may be displayed superimposed on an object such as a building or runway. For example, the three-dimensional information may be provided to a person in charge via a device that provides virtual reality (VR) or augmented reality (AR). Representing the managed airspace three-dimensionally as in FIG. 12 makes it easier to intuitively understand the airspace in which the drone was detected.

[0041] FIG. 13 is a conceptual diagram illustrating an example of the display of shared information output from an information sharing device according to the present disclosure. In the shared information of FIG. 13, the detected drone and the airspace are represented, including the vertical position (z) in addition to the position (x, y) in the horizontal plane. In the example of FIG. 13, the drone detected in the managed airspace is displayed in a three-dimensional representation of the managed airspace. Displaying the drone in the three-dimensional representation of the managed airspace as in FIG. 13 allows the position of the detected drone to be intuitively associated with the airspace. For example, three-dimensional information including a three-dimensional grid and the drone may be displayed superimposed on objects such as buildings and runways. For example, the three-dimensional information may be provided to personnel via a device that provides virtual reality (VR) or augmented reality (AR).

[0042] Fig. 14 is a conceptual diagram showing an example of information collection by an information sharing device according to the present disclosure. In the example of Fig. 14, the information collection unit 11 is configured to collect drone sighting information in addition to drone information. The drone sighting information includes at least information regarding the time and location at which the drone was sighted. There are no particular limitations on the method for providing the sighting information.

[0043] As an example, drone sighting information is provided by users using an airport. For example, the users verbally provide drone sighting information to relevant parties, such as airport security personnel. For example, the users provide drone sighting information to relevant departments to which airport security personnel belong, or to the police, via email or telephone. For example, the users provide drone sighting information using an account or application of a social networking service (SNS) operated by the airport. If incentives are given to information providers in response to the provision of drone sighting information, the number of sighting information provided may increase. Furthermore, if incentives are given to information providers in response to the quality of the drone sighting information, the quality of the sighting information may improve. For example, the information collecting unit 11 collects drone sighting information posted by users via their own SNS. For example, drone sighting information may be extracted from posted comments about the airport using an analysis model trained on past sighting information. For example, the analysis model can be generated by training comments about drones that have been sighted in the past using a machine learning technique.

[0044] As an example, drone sighting information is provided by personnel who operate and manage an airport. For example, security personnel provide drone sighting information via the monitoring system 110. For example, inspection personnel provide drone sighting information via the flight support system 120. For example, air traffic control personnel provide drone sighting information via the air traffic control system 130. For example, air traffic control personnel provide sighting information obtained from the pilot of an aircraft.

[0045] For example, drone sightings may be extracted from images captured of controlled airspace, including in and around airports. For example, drone sightings may be extracted from videos and images included in posts about airports using an analytical model trained on past sightings. For example, the analytical model may be generated by using machine learning techniques to train videos and images of drones previously seen.

[0046] (operation) Next, an example of the operation of the information sharing device according to this embodiment will be described with reference to the drawings. Fig. 15 is a flowchart showing an example of the operation of the information sharing device according to the present disclosure. In describing the processing according to the flowchart in Fig. 15, the components of the information sharing device 10 will be the main focus. The main focus of the processing according to the flowchart in Fig. 15 may be the information sharing device 10.

[0047] 15, first, the information collection unit 11 collects drone information detected inside and around the managed facility (step S11). The drone information includes location information and identification information for each drone.

[0048] Next, the plan acquisition unit 12 acquires an operation plan for the drone in and around the managed facility (step S12). The operation plan includes identification information (drone ID) of the drone that is permitted to operate in or around the managed facility during the time period that includes the time when the drone information is collected.

[0049] Next, the determination unit 13 refers to the operation plan and determines whether the drone detected inside or around the managed facility is an authorized drone or a suspicious drone (step S13). A drone registered in the operation plan is an authorized drone. On the other hand, a drone not registered in the operation plan is a suspicious drone.

[0050] Next, the information sharing unit 15 transmits information including the determination result to devices used in multiple related departments that manage the managed airspace (step S14). For example, the information including the determination result is transmitted to terminal devices used by security personnel, inspection personnel, and control personnel. For example, the information including the determination result may be transmitted to wireless communication devices carried by security personnel.

[0051] As described above, the information sharing device of this embodiment includes an information collection unit, a plan acquisition unit, a determination unit, and an information sharing unit. The information collection unit collects drone information about drones detected in the managed airspace. The plan acquisition unit acquires flight plans for drones in the managed airspace. The determination unit uses the collected drone information to determine whether a drone detected in the managed airspace is an authorized drone or a suspicious drone. For example, the determination unit determines that a drone registered in the flight plan is an authorized drone. On the other hand, the determination unit determines that a drone not registered in the flight plan is a suspicious drone. The information sharing unit transmits information indicating whether a drone detected in the managed airspace is an authorized drone or a suspicious drone to devices used in multiple related departments that manage the managed airspace.

[0052] The information sharing device of this embodiment determines that a drone registered in an operation plan is an authorized drone. On the other hand, the information sharing device determines that a drone not registered in an operation plan is an authorized drone. As an information sharing platform, drone information about drones detected in a managed airspace is transmitted to devices used by multiple related departments that manage the managed airspace. The multiple related departments that manage the managed airspace can share drone information detected in the managed airspace in real time. In other words, according to this embodiment, it is possible to share information about drones in a managed airspace with multiple related departments that manage the operation of managed facilities.

[0053] In one aspect of this embodiment, the drone information includes location information of the drone detected in the managed airspace and an identifier for uniquely identifying the detected drone. According to this aspect, the drone's location information and identifier can be used to determine whether the drone is an authorized drone or a suspicious drone.

[0054] In one aspect of this embodiment, the information sharing unit transmits display information showing drones detected in each of a plurality of airspaces included in the managed airspace to devices used in a plurality of related departments that manage the managed facility. The display information is provided in a display state in which an indication of the drones detected in each of the plurality of airspaces is superimposed on a map that clearly shows the plurality of airspaces included in the managed airspace. According to this aspect, the location of the drones detected in the managed airspace can be intuitively grasped.

[0055] In one aspect of this embodiment, the information sharing unit transmits information about suspicious aircraft detected in each of a plurality of airspaces included in the managed airspace with content customized for each of a plurality of related departments that manage the managed facility. According to this aspect, the shared information shared among the plurality of related departments can be provided with content optimized for each related department.

[0056] In one aspect of this embodiment, the information collection unit collects sighting information about drones sighted in the managed airspace. The determination unit uses the collected sighting information to determine whether a drone detected in the managed airspace is an authorized drone or a suspicious drone. In this aspect, drone information is collected including not only information from the operator of the managed facility but also information from the user of the managed facility. Therefore, this aspect can reduce the risk of drones in the managed airspace being overlooked. For example, a drone brought into an airport may suddenly begin flying in the managed facility. Utilizing sighting information can potentially reduce the risk of such drones being overlooked.

[0057] (Second embodiment) Next, an information sharing device according to a second embodiment will be described with reference to the drawings. The information sharing device according to this embodiment differs from the first embodiment in that it determines whether a drone is an authorized drone or a suspicious drone based on the drone's movement information. The movement information is information that represents the movement of the drone. For example, the movement information includes a trajectory (trail) obtained by tracking the movement of the drone. The movement information also includes information that represents the movement of not only drones but also flying animals such as birds and bats.

[0058] (composition) 16 is a block diagram showing an example of the configuration of an information sharing device according to the present disclosure. The information sharing device 20 includes an information collection unit 21, a plan acquisition unit 22, a determination unit 23, a determination model 24, and an information sharing unit 25. For example, the information sharing device 20 is implemented in a server or computer located inside a facility to be managed. The information sharing device 20 may also be implemented in a server located in a data center outside the facility to be managed, or in the cloud.

[0059] The information collection unit 21 collects information (drone information) about drones flying in the managed airspace. For example, the information collection unit 21 collects drone information via wireless communication. The information collection unit 21 collects drone information about drones detected by a monitoring system. The drone information includes location information and identification information for each of multiple drones flying in the managed airspace. For example, the identification information includes an identifier (ID) for uniquely identifying the drone. For example, the identification information is transmitted from a device such as a remote ID mounted on the drone.

[0060] The information collection unit 21 also acquires drone activity information. The activity information includes information indicating the dynamic state of the drone. For example, the activity information may be extracted from videos or images of the managed airspace collected by a monitoring system.

[0061] The plan acquisition unit 22 has the same configuration as the plan acquisition unit 12 of the first embodiment. The plan acquisition unit 22 acquires a flight plan for the drone in the managed airspace. The flight plan includes a plan for the flight of the drone inside and around the airport, which corresponds to the managed airspace. The flight plan for the drone in the vicinity of the airport is acquired from a drone operation management system (not shown) operated by a national or local government. The flight plan for the drone inside the airport is acquired from a flight support system that manages the operation of inspection drones inside the airport. Note that if a flight plan is not used in determining the drone, the plan acquisition unit 22 may be omitted.

[0062] The determination unit 23 acquires the drone information and movement information collected by the information collection unit 21. The determination unit 23 uses the determination model 24 to determine whether the drone included in the drone information is an authorized drone or a suspicious drone. The determination model 24 is a machine learning model that determines whether the drone is an authorized drone or a suspicious drone based on input movement information. The determination unit 23 inputs the acquired movement information into the determination model 24. The determination unit 23 determines whether the drone is an authorized drone or a suspicious drone based on information output from the determination model 24 based on input movement information. The determination model 24 may be stored in an external storage device constructed on a cloud, a server, or the like. In this case, the determination unit 23 uses the determination model 24 via an interface (not shown) connected to the storage device.

[0063] Dynamic information is information that describes the movement of a drone. For example, dynamic information includes dynamic information about the drone's location, speed, flight mode, flight trajectory, etc. Location information includes the drone's position (latitude and longitude) and altitude within managed airspace. Speed ​​includes horizontal and vertical speeds. Flight mode includes flight patterns such as hovering and cruising. Flight trajectory includes the movement trajectory of a drone flying in a specific pattern within or around an airport. Below are some examples of how to identify a suspicious aircraft based on dynamic information.

[0064] For example, a drone conducting an inspection in a managed airspace may hover for a long time or make frequent passes at a specific location included in the managed airspace. If the drone has an approved flight plan, such behavior is likely to indicate that the drone is authorized. Therefore, a drone with an approved flight plan for an inspection within an airport that hovers for a long time or makes frequent passes at a specific location can be determined to be conducting an inspection. On the other hand, if a drone without an approved flight plan exhibits such behavior, it may be attempting to launch some kind of attack on a facility near the specific location. Therefore, a drone with an approved flight plan for an inspection within an airport that hovers for a long time or makes frequent passes at a specific location can be determined to be a suspicious drone.

[0065] For example, a drone approaching an airport from its periphery toward its interior at a faster than normal speed may be launching some kind of attack on the airport. Similarly, a drone approaching an airport from above at a faster than normal speed may be launching some kind of attack on the airport. Furthermore, a drone moving from the interior of the airport toward its periphery at a faster than normal speed may be attempting to take some kind of information out of the airport. Similarly, a drone rapidly ascending above the airport at a faster than normal speed may be attempting to take some kind of information out of the airport. Therefore, a drone moving faster than normal in managed airspace can be determined to be a suspicious aircraft.

[0066] For example, a suspicious aircraft attempting to find an intrusion route from the perimeter of an airport to the interior may search for weakly secured areas around the airport's perimeter. Furthermore, a suspicious aircraft attempting to find an intrusion route may weave its way through the airport's perimeter. Therefore, a drone showing a specific flight path within the airport perimeter can be determined to be a suspicious aircraft.

[0067] For example, a suspicious aircraft attempting to collect internal information about an airport may fly along a similar flight route multiple times. Also, a drone intended to collect specific information may fly around a specific facility in sequence. Therefore, a drone showing a specific flight trajectory can be determined to be suspicious.

[0068] FIG. 17 is a conceptual diagram illustrating an example of learning of a determination model according to the present disclosure. The determination model 24 is a machine learning model. For example, the determination model 24 is a model trained using a dataset in which drone dynamic information is used as an explanatory variable and an alert rank corresponding to the dynamic state is used as a target variable, as training data. For example, the dynamic state includes information indicating the movement of the drone as described above. The alert rank indicates the degree of alert for drones flying in managed airspace. The alert rank is expressed as a numerical value set according to the level of danger to the airport. The level of danger to the airport is set according to a magnitude relationship with a predetermined reference value. For example, the alert rank is set according to the distance from the lower surface of the managed airspace. In this case, the smaller the distance from the lower surface, the higher the alert rank is set. For example, the alert rank is set according to the speed of the drone. In this case, the faster the drone's speed, the higher the alert rank is set. For example, the alert rank is set according to the size of the drone. In this case, the larger the drone, the higher the alert rank is set. For example, the alert rank is set according to the shape of the drone. In this case, the closer the shape is to a pre-registered shape, the higher the alert level is set. For example, if the alert level is set according to the shape of the drone, animals such as birds can also be detected. Therefore, if a bird is detected, the alert level can be set according to its distance from the runway.

[0069] For example, the determination model 24 is generated by learning using a linear regression algorithm. For example, the determination model 24 is generated by learning using a support vector machine (SVM) algorithm. For example, the determination model 24 is generated by learning using a Gaussian process regression (GPR) algorithm. For example, the determination model 24 is generated by learning using a random forest (RF) algorithm. For example, the determination model 24 may be generated by unsupervised learning that classifies the subject that generated the feature data according to the feature data. There are no particular limitations on the algorithm used to train the determination model 24. For example, the determination model 24 may be a machine learning model such as an incomplete heterogeneous variational autoencoder or a random forest. An incomplete heterogeneous variational autoencoder can estimate the alert rank even if information contained in the dynamic information is missing.

[0070] FIG. 18 is a conceptual diagram showing an example of determination using a determination model according to the present disclosure. The determination model 24 is a model generated using a machine learning technique as shown in FIG. 17. The determination model 24 outputs an alert rank corresponding to input behavioral information. A single piece of behavioral information may be input to the determination model 24, or multiple pieces of behavioral information may be input. Using multiple pieces of behavioral information allows the alert level to be set from multiple aspects, resulting in a more accurate alert rank determination.

[0071] The determination unit 23 inputs the dynamic information for each drone into the determination model 24. The determination model 24 receives the dynamic information, including dynamic information related to the drone's location, speed, flight mode, flight trajectory, and the like. In response to the input dynamic information, the determination model 24 outputs an alert rank corresponding to the dynamic information. The determination unit 23 generates alert information including the alert rank output from the determination model 24. For example, the determination unit 23 generates alert information including a notification that a drone with a high alert rank has been detected. Such a notification allows the user to recognize that a drone with a high alert rank has been detected in a managed airspace. For example, the determination unit 23 generates, as the alert information, an alert map in which the alert ranks of drones detected in airspace included in a map indicating the managed airspace are mapped. Such an alert map allows the user to visually grasp airspace in which a drone with a high alert rank has been detected in the managed airspace.

[0072] FIG. 19 is a conceptual diagram illustrating an example of a warning map generated by an information sharing device according to the present disclosure. In the warning map of FIG. 19, cells representing airspaces included in a managed airspace are displayed in different display formats depending on the warning rank of a drone detected in the airspace. For example, the warning ranks are represented by different colors or patterns. Airspaces in which drones with high warning ranks have been detected may be displayed in a flashing manner. In the example of FIG. 19, the warning ranks are represented as rank 1, rank 2, and rank 3. The higher the rank, the greater the level of warning. Airspaces with higher warning ranks are preferably displayed in a more conspicuous display format. Using a warning map such as that of FIG. 19 allows users to intuitively grasp airspaces in which drones with high warning ranks have been detected.

[0073] Furthermore, the determination unit 23 acquires the flight plan acquired by the plan acquisition unit 22. The determination unit 23 refers to the flight plan to determine whether the drone included in the drone information is an authorized drone or a suspicious drone. A drone that is authorized to operate around or inside the airport during a time period that includes the target time is registered in an flight plan that includes the target time. In other words, a drone registered in an flight plan that includes the target time is an authorized drone. On the other hand, a drone that is not registered in an flight plan that includes the target time is a suspicious drone. The determination unit 23 outputs information including a determination result indicating whether the drone is an authorized drone or a suspicious drone for each detected drone to the information sharing unit 25.

[0074] For example, the determination unit 23 is configured to determine whether a drone is authorized or suspicious using the movement information and the flight plan. This configuration allows for two-stage determination of whether a drone is authorized or suspicious, thereby improving the accuracy of the determination. For example, two-stage determination using the movement information and the flight plan makes it easier to detect suspicious drones disguised as drones registered in the flight plan. The determination unit 23 may be configured to make a determination using the flight plan when it is not possible to determine whether a drone is authorized or suspicious using the movement information alone. This configuration allows for supplemental determination using the flight plan, thereby improving the accuracy of the determination. Furthermore, the determination unit 23 may be configured to make a determination using the movement information when it is determined that a drone is suspicious using the flight plan. This configuration allows for supplemental determination using the movement information when it is not possible to determine whether a drone is authorized or suspicious using the flight plan alone.

[0075] The information sharing unit 25 has the same configuration as the information sharing unit 15 in the first embodiment. The information sharing unit 25 distributes information including the determination result by the determination unit 23 to relevant departments that operate the airport, which is a facility to be managed. In this embodiment, the information sharing unit 25 distributes the shared information to a monitoring system, a flight assistance system, and an air traffic control system. The shared information distributed to the monitoring system, the flight assistance system, and the air traffic control system is shared among the personnel who use these systems.

[0076] The information sharing device 20 is connected to a monitoring system, a flight operation support system, and an air traffic control system via a network. For example, the monitoring system, the flight operation support system, and the air traffic control system are built on a cloud or a server connected to the information sharing device 20 via a network. The monitoring system, the flight operation support system, and the air traffic control system may be implemented on a server or terminal device located within an airport. The information shared with the monitoring system, the flight operation support system, and the air traffic control system is referenced by personnel using those systems.

[0077] FIG. 20 is a conceptual diagram showing an example in which shared information output from an information sharing device according to the present disclosure is shared with related departments. FIG. 20 shows an example in which personnel belonging to different related departments are reviewing the same shared information. The shared information is delivered from the information sharing device 20 to terminal device 280A via a monitoring system. The shared information is delivered from the information sharing device 20 to terminal device 280B via an aircraft flight support system. The shared information is delivered from the information sharing device 20 to terminal device 280C via an air traffic control system. The same shared information delivered from the information sharing device 20 is displayed on the screens of terminal device 280A, terminal device 280B, and terminal device 280C. The screens of terminal device 280A, terminal device 280B, and terminal device 280C display the same information: "Suspicious aircraft with alert level 3 in area C5 inside the airport." The security personnel are reviewing the shared information displayed on the screen of terminal device 280A. The inspector is checking the shared information displayed on the screen of terminal device 280B. The control person is checking the shared information displayed on the screen of terminal device 280C. According to the example of FIG. 20, persons belonging to different related departments can check the common shared information. For example, the shared information may be customized for each related department or provided by different devices for each related department.

[0078] (operation) Next, an example of the operation of the information sharing device according to this embodiment will be described with reference to the drawings. Fig. 21 is a flowchart showing an example of the operation of the information sharing device according to the present disclosure. In describing the processing according to the flowchart in Fig. 21, the components of the information sharing device 20 will be the main focus. The main focus of the processing according to the flowchart in Fig. 21 may be the information sharing device 20.

[0079] 21, first, the information collection unit 21 collects drone information detected inside and around the managed facility (step S21). The drone information includes location information and identification information for each drone.

[0080] Next, the plan acquisition unit 22 acquires the movement information / operation plan of the drone in and around the managed facility (step S22). The operation plan includes the identification information (drone ID) of the drone that is permitted to operate in or around the managed facility during the time period that includes the time when the drone information is collected.

[0081] Next, the determination unit 23 refers to the operation plan and determines whether the drone detected inside or around the managed facility is an authorized drone or a suspicious drone (step S23). The plan acquisition unit 22 refers to the operation plan and determines whether the drone is an authorized drone or a suspicious drone. A drone registered in the operation plan is an authorized drone. On the other hand, a drone not registered in the operation plan is a suspicious drone.

[0082] If a suspicious machine is detected (Yes in step S24), the determination unit 23 determines the alert rank using the determination model 24 (step S25). If a suspicious machine is not detected (No in step S24), the process proceeds to step S26.

[0083] If the answer is No in step S24, or after step S25, the information sharing unit 25 transmits information including the determination result to devices used in multiple related departments that manage the managed airspace (step S26). For example, the information including the determination result is transmitted to terminal devices used by security personnel, inspection personnel, and control personnel. For example, the information including the determination result may be communicated to wireless communication devices held by security personnel.

[0084] As described above, the information sharing device of this embodiment includes an information collection unit, a plan acquisition unit, a determination unit, and an information sharing unit. The information collection unit collects drone information about drones detected in the managed airspace. The information collection unit also collects dynamic information indicating the movement of the drones detected in the managed airspace. The plan acquisition unit acquires a flight plan for the drone in the managed airspace. The determination unit uses the collected drone information to determine whether the drone detected in the managed airspace is an authorized drone or a suspicious drone. For example, the determination unit uses the collected dynamic information to determine whether the drone detected in the managed airspace is an authorized drone or a suspicious drone. The information sharing unit transmits information indicating whether the drone detected in the managed airspace is an authorized drone or a suspicious drone to devices used in multiple related departments that manage the managed airspace.

[0085] The information sharing device of this embodiment uses movement information of a drone detected in a managed airspace to determine whether the drone detected in the managed airspace is an authorized drone or a suspicious drone. Therefore, according to this aspect, it is possible to determine whether the drone detected in the managed airspace is an authorized drone or a suspicious drone without using a flight plan. The information sharing device of this embodiment serves as an information sharing infrastructure and transmits drone information about the drone detected in the managed airspace to devices used in multiple related departments that manage the managed airspace. The multiple related departments that manage the managed airspace can share drone information detected in the managed airspace in real time. In other words, according to this embodiment, it is possible to share information about drones in the managed airspace with multiple related departments that manage the operation of managed facilities.

[0086] In one aspect of this aspect, the determination unit determines the alert rank of a drone detected in a managed airspace using a determination model that outputs an alert rank indicating the alert level of the drone in response to input movement information. The information sharing unit transmits information including the alert rank to devices used by multiple related departments that manage the managed facility. According to this aspect, the alert rank of a drone detected in a managed airspace can be determined using a determination model generated based on past knowledge.

[0087] (Third embodiment) Next, an information sharing device according to a third embodiment will be described with reference to the drawings. The information sharing device according to this embodiment has a simplified configuration of the information sharing device according to the first and second embodiments. For example, the functions of the components included in the information sharing device according to this embodiment are realized by the functions of the components included in the information sharing device according to the first and second embodiments.

[0088] (composition) 22 is a block diagram showing an example of the configuration of an information sharing device according to the present disclosure. The information sharing device 30 includes an information collection unit 31, a determination unit 33, and an information sharing unit .

[0089] The information collection unit 31 collects drone information about drones detected in the managed airspace. The determination unit 33 uses the collected drone information to determine whether the drone detected in the managed airspace is an authorized drone or a suspicious drone. The information sharing unit 35 transmits information indicating whether the drone detected in the managed airspace is an authorized drone or a suspicious drone to devices used in multiple related departments that manage the managed airspace.

[0090] (operation) Fig. 23 is a flowchart showing an example of the operation (information sharing method) of the information sharing device according to the present disclosure. In describing the processing according to the flowchart of Fig. 23, the components of the information sharing device 30 will be described as the subject of the operations. The subject of the operations according to the flowchart of Fig. 23 may be the information sharing device 30.

[0091] In FIG. 23, first, the information collection unit 31 collects drone information about drones detected in the managed airspace including above and around the managed facilities (step S31).

[0092] Next, the determination unit 33 uses the collected unmanned aircraft information to determine whether the unmanned aircraft detected in the managed airspace is an authorized aircraft or a suspicious aircraft (step S32).

[0093] Next, the information sharing unit 35 transmits information indicating whether the drone detected in the managed airspace is an authorized drone or a suspicious drone to equipment used in multiple relevant departments that manage the managed facility (step S33).

[0094] The information sharing device of this embodiment serves as an information sharing infrastructure and transmits drone information about drones detected in managed airspace to devices used by multiple relevant departments that manage the managed airspace. The multiple relevant departments that manage the managed airspace can share drone information detected in the managed airspace in real time. In other words, this embodiment makes it possible to share information about drones in managed airspace with multiple relevant departments that manage the operation of managed facilities.

[0095] (Hardware) Next, an example of a hardware configuration for executing the control and processing in the present disclosure will be described with reference to the drawings. Here, an information processing device 90 (computer) in Fig. 24 is shown as an example of such a hardware configuration. The information processing device 90 in Fig. 24 is an example of a configuration for executing the control and processing in the present disclosure, and does not limit the scope of the present disclosure.

[0096] As shown in Fig. 24, an information processing device 90 includes a processor 91, a memory 92, an auxiliary storage device 93, an input / output interface 95, and a communication interface 96. In Fig. 24, interface is abbreviated as I / F (Interface). The information processing device 90 may include a plurality of at least any of the processor 91, memory 92, auxiliary storage device 93, input / output interface 95, and communication interface 96. The processor 91, memory 92, auxiliary storage device 93, input / output interface 95, and communication interface 96 are connected to each other via a bus 98 so as to be able to communicate data with each other. The processor 91, memory 92, auxiliary storage device 93, and input / output interface 95 are also connected to a network such as the Internet or an intranet via the communication interface 96.

[0097] The processor 91 loads a program (instructions) stored in an auxiliary storage device 93 or the like into the memory 92. For example, the program is a software program for executing the control and processing in the present disclosure. The processor 91 executes the program loaded into the memory 92. The processor 91 executes the program to execute the control and processing in the present disclosure. The processor 91 may be configured by a single piece of hardware or may be configured by multiple pieces of hardware.

[0098] The memory 92 is a storage device having an area in which a program is loaded. The processor 91 loads a program stored in an auxiliary storage device 93 or the like into the memory 92. The memory 92 is realized by a volatile memory such as a DRAM (Dynamic Random Access Memory). Alternatively, a non-volatile memory such as an MRAM (Magnetoresistive Random Access Memory) may be used as the memory 92. The memory 92 may be configured by a single piece of hardware or by multiple pieces of hardware.

[0099] The auxiliary storage device 93 stores various data such as programs. For example, the auxiliary storage device 93 is realized by a local disk such as a hard disk or flash memory.
