[1] First Example FIG. 1 is a diagram for explaining an outline of the disaster prevention drone 10 according to the first embodiment. The disaster prevention drone 10 is a device for preventing people from suffering a disaster due to an event that causes a disaster, that is, a device for disaster prevention. Events that cause disasters are, for example, earthquakes, tsunamis, landslides, floods, fires, etc., and are events that damage people. Events that cause disasters include not only natural phenomena such as earthquakes, but also events that occur due to human causes such as misfires.

The disaster prevention drone 10 is an air vehicle that autonomously flies according to a predetermined flight path and a flight path determined and determined by the own aircraft. In this embodiment, one or more rotor blades are provided and their rotations are provided. It is a rotorcraft-type flying object that flies by rotating its wings. The disaster prevention drone 10 has a function of measuring the position and altitude of its own aircraft (that is, spatial coordinates in three-dimensional space), and by controlling the flight speed and flight direction while measuring the spatial coordinates, the flight path. Fly along.

The disaster prevention drone 10 is located in an area where it is predicted that a disaster will occur due to the occurrence of an earthquake or the like (damaged by an event such as an earthquake. It is also called a disaster or suffer a disaster) (hereinafter referred to as "damage prediction area"). It is placed in a facility within a flight distance to a facility or its damage prediction area. The flightable distance here means the distance that can be returned to the starting point after arriving at the damage prediction area and then flying within the damage prediction area for a certain distance. In FIG. 1, the disaster prevention drone 10 is arranged in the drone arrangement facility 2 in a place where it can fly in the tsunami damage prediction area A1 and the landslide damage prediction area A2.

When a tsunami warning or the like (a large tsunami warning, a tsunami warning, or a tsunami warning) is issued, the disaster prevention drone 10 flies on the flight route R1 and calls for evacuation of people in the tsunami damage prediction area A1. Output etc. In addition, the disaster prevention drone 10 outputs a message voice calling for evacuation to people in the landslide damage prediction area A2 by flying on the flight path R2 when a landslide disaster warning is issued on M1 mountain.

The disaster prevention drone 10 has a function of wirelessly communicating with a network including a mobile communication network and the Internet. From these networks, for example, disaster prevention information provided by a specific telecommunications carrier is transmitted. The disaster prevention information is at least information indicating the occurrence of an event that causes a disaster such as the above-mentioned earthquake and the area that is affected by the event (hereinafter referred to as "disaster area"). The occurrence of an event here includes both that the event has already occurred and that the event is about to occur.

For example, in the case of a tsunami, the occurrence of the tsunami is predicted from the epicenter and scale of the earthquake, and disaster prevention information is provided before the tsunami arrives, and of course, disaster prevention information is continuously provided even after the tsunami arrives. Not limited to tsunamis, if a disaster is predicted before the event itself occurs (for example, if a landslide or flood is predicted when precipitation or river water level exceeds the standard), that Information indicating that an event is about to occur and the area (disaster area) where the event is expected to cause a disaster is provided as disaster prevention information.

A specific telecommunications carrier provides, for example, Earthquake Early Warnings and tsunami warnings sent by the Japan Meteorological Agency, and disaster information sent by local governments as disaster prevention information. The service that provides this disaster prevention information is called Area Mail or breaking news mail, etc., and the telecommunications carrier is limited to communication terminals located in a specific range including the area where the disaster occurred and the area where the disaster is predicted to occur. I try not to send disaster prevention information.

The disaster prevention drone 10 also has a function of receiving a disaster prevention administrative radio transmitted by a local public body (municipal office, etc.). Local public organizations have an organization that collects disaster prevention information such as the disaster countermeasures headquarters, and the registration system in which the disaster prevention information collected by that organization and the disaster prevention information from the country such as the Meteorological Agency are broadcast with the disaster prevention administrative radio or the disaster prevention administrative radio. It is sent by the mail of. The disaster prevention administrative radio is basically transmitted so that it can be received at least within the jurisdiction of the local public body (within the area of the local public body) of the source. On the other hand, registration-based e-mail is a service that sends disaster prevention information to a pre-registered e-mail address of a local public body operating a disaster prevention radio, and can receive disaster prevention information even outside the jurisdiction of the local public body.

The tsunami damage prediction area A1 and the landslide damage prediction area A2 are both areas within the jurisdiction of the same local public body. The drone placement facility 2 is also selected from facilities within the same jurisdiction. Therefore, the disaster prevention drone 10 receives disaster prevention information regarding disasters occurring in the tsunami damage prediction area A1 and the landslide damage prediction area A2, and outputs a message voice calling for evacuation by flying in the damage prediction area as described above. You can do it.

It may be configured to include, and a part or all of each functional block may be realized by the hardware. For example, the processor 11 may be implemented on at least one of these hardware.

The function group described below is realized by the processor 11 of the disaster prevention drone 10 executing a program and controlling each part.
FIG. 3 shows the functional configuration realized by the disaster prevention drone 10. The disaster prevention drone 10 includes a disaster prevention information acquisition unit 101, a flight route determination unit 102, a flight route storage unit 103, a flight start instruction unit 104, a flight control unit 111, a flight unit 112, a position measurement unit 113, and the like. It includes an altitude measurement unit 114, a direction measurement unit 115, a notification data acquisition unit 121, a notification unit 122, and a notification data storage unit 123.

The disaster prevention information acquisition unit 101 acquires the above-mentioned disaster prevention information, that is, information indicating the occurrence of an event such as an earthquake that causes a disaster and the area (disaster area) that is affected by the event. The disaster prevention information acquisition unit 101 is an example of the "acquisition unit" of the present invention. The disaster prevention information acquisition unit 101 acquires disaster prevention information (disaster prevention information provided by Area Mail or emergency bulletin mail and disaster prevention information provided by disaster prevention administration radio) received by the communication device 14 described above.

The disaster prevention information acquisition unit 101 supplies the acquired disaster prevention information to the flight route determination unit 102, the flight start instruction unit 104, and the notification data acquisition unit 121. The flight route determination unit 102 determines the flight route for flying in the disaster area indicated by the disaster prevention information acquired by the disaster prevention information acquisition unit 101. The flight path determination unit 102 is an example of the “determination unit” included in the flying object of the present invention. The flight path determination unit 102 determines the flight path with reference to the flight path storage unit 103.

The flight route storage unit 103 stores route information indicating a plurality of flight routes associated with a plurality of events that cause a disaster. The flight path storage unit 103 is an example of the "path storage unit" of the present invention.
FIG. 4 shows an example of stored route information. In the example of FIG. 4, the flight path storage unit 103 associates the event that causes a disaster called "tsunami" with the route information represented by the latitude and longitude of "lat1_lng1, lat11_lng11, ..., Lat17_lng17, lat1_lng1". I remember.

“Lat1_lng1” indicating the departure point and the arrival point is the latitude and longitude of the drone placement facility 2 shown in FIG. 1, and the other seven latitudes and longitudes are the latitudes and the latitudes of the seven corners included in the flight path R1 shown in FIG. It is the longitude. Further, the flight route storage unit 103 stores the route information represented by the latitude and longitude of "lat1_lng1, lat21_lng21, ..., Lat27_lng27, lat1_lng1" in association with the event causing the disaster "landslide". There is.

The starting point and the arriving point are the latitude and longitude of the drone placement facility 2 as in the case of the tsunami, and the other seven latitudes and longitudes are the latitudes and longitudes of the seven corners included in the flight path R2 shown in FIG. In this way, the flight path storage unit 103 stores the route information indicating the flight path R1 in association with the event of the tsunami, and stores the route information indicating the flight path R2 in association with the event of the landslide.

As shown in FIG. 1, the flight paths R1 and R2 are set by connecting routes that draw a straight line. The route information is, for example, information in which the latitudes and longitudes of the corners that are the joints of these linear routes are arranged in the order of passage. The departure point and arrival point of the flight path are preferably positions (placement positions) where the disaster prevention drone 10 is placed as shown in the example of FIG. 4, but may be other positions.

Even if the departure point and the arrival point are far from the placement position, the disaster prevention drone 10 autonomously flies on the flight path connecting the placement position to the departure point and the arrival point to the placement position. The flight route shown in FIG. 1 and the route information shown in FIG. 4 are examples, and are not limited thereto. For example, not only a straight line but also a curved path may be used as a flight path. In addition, a flight path specified up to altitude may be used.

When the disaster prevention information is supplied from the disaster prevention information acquisition unit 101, the flight route determination unit 102 serves as a flight route for flying in the disaster area indicated by the supplied disaster prevention information (disaster prevention information acquired by the disaster prevention information acquisition unit 101). Of the plurality of flight routes indicated by the route information stored in the flight route storage unit 103, the flight route associated with the event (event causing the disaster) indicated by the disaster prevention information is determined.

For example, the flight route determination unit 102 indicates disaster prevention information indicating a tsunami warning, that is, disaster prevention information indicating that the event causing the disaster is a tsunami (for example, disaster prevention information provided by an area mail indicating a tsunami warning or a disaster prevention administrative radio). Is acquired by the disaster prevention information acquisition unit 101, the flight route R1 stored in association with the event of a tsunami is determined as the flight route to fly in the disaster area (tsunami damage prediction area A1) indicated by the disaster prevention information. ..

Further, when the flight path determination unit 102 acquires disaster prevention information indicating a landslide disaster, that is, disaster prevention information indicating that the event causing the disaster is a landslide, it is stored in association with the phenomenon of a landslide. The flight route R2 is determined as the flight route to fly in the disaster area (landslide damage prediction area A2) indicated by the disaster prevention information. The flight route determination unit 102 reads out the route information indicating the determined flight route from the flight route storage unit 103 and supplies it to the flight control unit 111.

The flight start instruction unit 104 instructs the flight control unit 111 to start the flight when the disaster prevention information is acquired by the disaster prevention information acquisition unit 101. The flight start instruction unit 104 is an example of the "instruction unit" included in the flying object of the present invention. When the disaster prevention information is supplied from the disaster prevention information acquisition unit 101, the flight start instruction unit 104 gives this instruction by supplying instruction data indicating the flight start instruction to the flight control unit 111.

The flight control unit 111 controls the flight along the flight path determined by the flight path determination unit 102 when the flight start instruction unit 104 gives an instruction to start the flight. The flight control unit 111 is an example of the "control unit" of the present invention. The flight control unit 111 controls the operation of the flight unit 112 in order to perform this flight control. The flight unit 112 is a function of flying the own aircraft (disaster prevention drone 10), and in this embodiment, the rotor included in the flight device 15 is rotated to fly the own aircraft. The flight unit 112 is an example of the "flying unit" of the present invention.

When the flight control unit 111 receives the instruction to start the flight, the flight control unit 111 instructs the position measurement unit 113, the altitude measurement unit 114, and the direction measurement unit 115 to start the measurement, respectively, in order to carry out the flight along the flight path. The position measurement unit 113 measures the current position of the own aircraft, and supplies position information (for example, latitude and longitude information) indicating the measured position to the flight control unit 111. The altitude measurement unit 114 measures the altitude of its own aircraft and supplies altitude information indicating the measured altitude (for example, information indicating the altitude in cm units) to the flight control unit 111.

The direction measuring unit 115 measures the direction in which the front of the own machine is facing, and provides directional information indicating the measured direction (for example, information indicating each direction at an angle of up to 360 degrees when true north is 0 degrees). It is supplied to the flight control unit 111. The measurement by the position measurement unit 113, the altitude measurement unit 114, and the direction measurement unit 115 is repeated at predetermined time intervals. The flight control unit 111 controls the flight unit 112 based on the position information, altitude information, and direction information that are repeatedly supplied in addition to the route information supplied from the flight route determination unit 102.

The flight control unit 111 determines the direction of the aircraft based on the measured position and direction and the latitude and longitude of the next corner indicated by the route information, and flies the aircraft toward the next corner. At that time, the flight control unit 111 controls the output of the flight unit 112 so that the measured altitude becomes, for example, an altitude determined as the flight altitude of the disaster prevention drone 10. The flight control unit 111 supplies the notification data acquisition unit 121 with position information indicating the current position of the own aircraft used for controlling the flight unit 112.

The notification data acquisition unit 121 acquires the disaster prevention information supplied from the disaster prevention information acquisition unit 101, that is, the notification data for notifying the disaster indicated by the disaster prevention information acquired by the disaster prevention information acquisition unit 101. The broadcast data includes, for example, sound data indicating the sound of a siren, character string data indicating a message character string to be displayed on a display, pattern data indicating an LED blinking pattern, and the like, in addition to the audio data indicating the message sound described above. The notification data acquisition unit 121 supplies the generated notification data to the notification unit 122.

The notification unit 122 notifies the disaster related to the disaster prevention information acquired by the disaster prevention information acquisition unit 101 based on the supplied notification data. The notification unit 122 is an example of the "notification unit" of the present invention. For example, when the notification data includes voice data indicating a message voice calling for evacuation of people, the notification unit 122 emits the message voice from a speaker to notify people that evacuation is necessary. It is performed as a notification regarding.

In addition, for example, the sound of a siren that sounds when an event that causes a disaster occurs by a local public body is defined, and it is assumed that the residents are informed of this. In that case, when the notification data includes sound data indicating the sound of the siren, the notification unit 122 causes the sound of the siren indicated by the notification data to be emitted from the speaker, thereby causing an event that causes a disaster. Notify people that an event has occurred as a disaster notification.

Further, when the notification data includes character string data indicating a message character string that calls for people to evacuate, the notification unit 122 needs to evacuate the people by displaying the message character string indicated by the notification data on the display. The notification that there is is performed as the notification regarding the disaster. The notification unit 122 performs this notification during the flight of the own aircraft by the flight control performed by the flight control unit 111. As a result, it is possible to notify people in the damage prediction area about the disaster.

Further, when the notification data includes pattern data indicating the blinking pattern of the LED, the notification unit 122 blinks the LED in the blinking pattern indicated by the notification data. The notification unit 122 blinks the LED together with other notifications. As a result, even people who are far from the disaster prevention drone 10 and cannot hear the output sound or see the image of the displayed message character string can see the blinking of the LED even from a distance, so approach the disaster prevention drone 10 It can be urged to check the sound and video.

Further, if the person in the traveling direction of the disaster prevention drone notices the blinking of the LED first, he / she pays attention to the disaster prevention drone 10, so that he / she can easily notice the message voice or the like when the disaster prevention drone 10 approaches. In this way, the notification unit 122 can enhance the effect of notification regarding a disaster by blinking the LED. As described above, the notification unit 122 notifies the disaster by a plurality of methods (a method of outputting a message voice, a method of outputting a siren sound, a method of displaying a message character string, and a method of blinking an LED together). Do.

In this embodiment, the notification data acquisition unit 121 acquires notification data from the notification data storage unit 123. The notification data storage unit 123 stores the various notification data described above. The notification data storage unit 123 stores the sound data indicating the above-mentioned siren sound and the LED blinking pattern data. Further, the notification data storage unit 123 stores the disaster prevention message DB 124 (DB: Data Base) and the area message DB 125 that store the voice data indicating the message voice and the character string data indicating the message character string.

The disaster prevention message DB 124 stores a message (specifically, voice data indicating a message voice and character string data indicating a message character string) in association with an event such as an earthquake that causes a disaster.
FIG. 5 shows an example of the information stored in the disaster prevention message DB 124. In the example of FIG. 5, the message "an earthquake has occurred. Please evacuate to a nearby wide area evacuation site when the shaking has subsided." Is associated with the event that causes the disaster called "earthquake." The message voice and the message character string may represent different messages, but in this embodiment, both represent the same message as shown in FIG.

Similarly, the events that cause disasters such as "tsunami", "landslide", and "fire" include "There is a risk of tsunami. Please move away from the coast or evacuate to a hill.", "There is a risk of landslide." The messages "Please move out of the sediment-related disaster warning area." And "A fire has occurred. There is a risk of fire spreading, so please leave the building and evacuate." All of these messages are messages calling for evacuation to prevent disasters when each event occurs. Since the evacuation method differs depending on the event that occurred, the message also differs for each event.

The area message DB 125 stores a message (specifically, voice data indicating a message voice and character string data indicating a message character string) associated with an area in the damage prediction area. The area referred to here is a plurality of areas included in the damage prediction area. For example, the tsunami damage prediction area A1 shown in FIG. 1 includes a densely populated private house area, a school area centered on a school, and a coastal area along the coast.

FIG. 6 shows an example of the information stored in the area message DB 125. In the example of FIG. 6, a message is associated with the area in the tsunami damage prediction area A1 for each event that causes a disaster. For example, if the event that causes a disaster is an "earthquake", the message "School C1 is a wide area evacuation area" is associated with the "dense area of private houses", and the event that causes a disaster is a "tsunami". , "Please evacuate to M2 mountain or tsunami evacuation facility C2.", And if the event that causes the disaster is "landslide", the message "Please evacuate away from M1 mountain." Are associated with each other.

In addition, if the event that causes the disaster is "earthquake", the message "Please evacuate to the schoolyard of school C1" is associated with the "school area", and the event that causes the disaster is "tsunami". ", The message" Please evacuate to M2 mountain "is associated. In addition, if the event that causes the disaster is "tsunami", the message "Please evacuate to tsunami evacuation facility C2" is associated with the "coastal area".

All of these messages are messages that convey specific evacuation methods that people should take according to their area in the damage prediction area. Since this specific evacuation method also differs depending on the event that occurred, the message also differs for each event. Also, depending on the area, it may not be necessary to evacuate in certain events (for example, there is no risk of landslides in school areas), in which case no message is prepared.

Further, the area message DB 125 stores range information indicating the latitude and the mild range included in each area. If the latitude and longitude measured as the current position by the position measuring unit 113 are included in the range, it means that the disaster prevention drone 10 is currently flying in the area corresponding to the range. In this way, the notification data storage unit 123 stores the message associated with the event causing the disaster and the message associated with the area in the disaster area (damage prediction area). The broadcast data storage unit 123 is an example of the "message storage unit" of the present invention.

The notification data acquisition unit 121 acquires a message stored in association with an event that causes a disaster indicated by the acquired disaster prevention information. The notification data acquisition unit 121 may acquire this message at any time after the disaster prevention information has been acquired. For example, as soon as the disaster prevention information is supplied, the notification data acquisition unit 121 acquires this message and supplies it to the notification unit 122.

Further, the notification data acquisition unit 121 is supplied with the current position measured by the position measurement unit 113 while the aircraft is flying on the flight path by the flight control of the flight control unit 111. The broadcast data acquisition unit 121 acquires a message stored in the broadcast data storage unit 123 in association with the area including the measured current position. The notification data acquisition unit 121 acquires this message based on the current position repeatedly measured during the flight of the flight path, and supplies the message to the notification unit 122 each time it is acquired.

When a message is supplied from the notification data acquisition unit 121, the notification unit 122 notifies the supplied message. As a result, the notification unit 122 notifies the message stored in association with the event causing the disaster indicated by the acquired disaster prevention information during the flight of the flight path. In addition, the notification unit 122 notifies the message stored in the notification data storage unit 123 in association with the area including the current position during the flight of the flight path.

Based on the above configuration, the disaster prevention drone 10 performs a notification process for notifying a disaster by flying on a flight path.
FIG. 7 shows an example of the operation procedure of the disaster prevention drone 10 in the notification process. This operation procedure is started when an event that causes a disaster occurs and disaster prevention information is provided. First, the disaster prevention drone 10 (disaster prevention information acquisition unit 101) acquires disaster prevention information indicating the occurrence of an event such as an earthquake that causes a disaster and the area affected by the event (step S11).

Next, the disaster prevention drone 10 (flight route determination unit 102) determines the flight route to fly in the disaster area indicated by the acquired disaster prevention information (step S12). Subsequently, the disaster prevention drone 10 (flight start instruction unit 104) instructs the start of flight when the disaster prevention information is acquired in step S11 (step S13). Next, the disaster prevention drone 10 (notification data acquisition unit 121) acquires notification data for performing notification regarding the disaster indicated by the acquired disaster prevention information (step S14).

In step S14, the disaster prevention drone 10 (notification data acquisition unit 121) acquires a message stored in association with an event causing a disaster, sound data indicating a siren sound, and LED blinking pattern data. To do. Subsequently, the disaster prevention drone 10 (flight control unit 111) starts flight control of the flight along the flight path determined in step S13 (step S15). Next, the disaster prevention drone 10 (position measuring unit 113) measures the current position of the own machine (step S21).

Subsequently, the disaster prevention drone 10 (notification data acquisition unit 121) acquires a message stored in the own machine (notification data storage unit 123) in association with the area including the measured current position (step S22). Next, the disaster prevention drone 10 (notification unit 122) notifies about the disaster based on the notification data acquired in steps S14 and S22 (step S23). Then, the disaster prevention drone 10 determines whether or not the drone has returned to the facility where the aircraft was located (step S24), and if it determines that the drone has not returned (NO), returns to step S21 and continues the operation. If it is determined that the player has returned (YES), this operation procedure is terminated.

In this embodiment, as described above, the disaster prevention drone 10 flies in the damage prediction area and notifies the disaster. As a result, it is possible to promote the evacuation of people in the disaster-stricken area (damage prediction area) as compared with the case where the disaster prevention drone 10 does not perform this notification. In addition, the disaster prevention drone 10 is dispatched (starts flight) when the disaster prevention information is acquired. As a result, the disaster prevention drone 10 can be dispatched at an earlier timing than when a person gives an instruction to start the flight, and the evacuation of people can be promoted more quickly.

Further, in the present embodiment, the flight path to actually fly is determined from the flight path stored in advance. As a result, it is possible to start the flight along the flight path at an earlier timing than when a new flight path is generated. Further, in this embodiment, the disaster prevention drone 10 flying in the damage prediction area notifies the message associated with the area including the current position. As a result, more appropriate notification (for example, notification of the nearest evacuation site in the area) can be performed for each area in the damage prediction area.

[2] Second Example The second embodiment of the present invention will be described below focusing on the differences from the first embodiment. In the first embodiment, the notification process is performed only by the disaster prevention drone 10, but in the second embodiment, the disaster prevention drone and the server device cooperate to perform the notification process.

FIG. 8 shows the overall configuration of the disaster prevention system 1 according to the second embodiment. The disaster prevention system 1 is a system for disaster prevention, and includes a disaster prevention drone 10a-1, 10a-2, 10a-3, ... (Hereinafter referred to as "disaster prevention drone 10a"), a server device 20, and a network. 3 and. The network 3 is a system including mobile communication, the Internet, and the like, and is a system that mediates communication between devices that access the own system. The disaster prevention drone 10a accesses the network 3 wirelessly, and the server device 20 accesses the network 3 by wire (or wirelessly).

Among the processes performed by the disaster prevention drone 10 of the first embodiment, the server device 20 performs flight route determination processing, notification data generation processing, and flight start instruction processing in this embodiment. The disaster prevention drone 10a transmits information necessary for causing the server device 20 to perform these processes (details will be described later) to the server device 20, and receives information indicating the results of those processes from the server device 20 for execution. Perform flight control similar to that described in the example.

The plurality of disaster prevention drones 10a are distributed and arranged near, for example, damage prediction areas all over the country. Each disaster prevention drone 10a is basically placed in a different facility near a different damage prediction area, but if there are many damage prediction areas in the vicinity or it is vast, multiple disaster prevention drones 10a may be located in the same facility. A drone ID (Identification) is assigned to each disaster prevention drone 10a as identification information for identifying the own machine, and each disaster prevention drone 10a stores the drone ID of the own machine.

FIG. 9 shows the hardware configuration of the server device 20. The server device 20 is a computer including a processor 21, a memory 22, a storage 23, a communication device 24, an input device 25, an output device 26, and a bus 27. The word "device" here can be read as a circuit, a device, a unit, or the like. Further, each device may be included one or more, or some devices may not be included.

The processor 21, the memory 22, the storage 23, and the bus 27 are hardware common to the device of the same name shown in FIG. The communication device 24 is hardware (transmission / reception device) for communicating between computers via a wired and / or wireless network like the communication device 14 shown in FIG. 2, but unlike the communication device 14, the disaster prevention administrative radio Does not receive. The input device 25 is an input device (for example, a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.) that receives an input from the outside. The output device 26 is an output device (for example, a display, a speaker, etc.) that outputs to the outside.

The functions described below are realized by the processors of the disaster prevention drone 10a and the server device 20 executing a program to control each part.
FIG. 10 shows a functional configuration realized by each device of the disaster prevention system 1. The disaster prevention drone 10a includes a disaster prevention information acquisition unit 101, a flight control unit 111, a flight unit 112, a position measurement unit 113, an altitude measurement unit 114, a direction measurement unit 115, and a notification unit 122 shown in FIG. In addition, an information communication unit 100 and a broadcast data holding unit 126 are provided.

Among the functions shown in FIG. 3, the server device 20 includes a flight path determination unit 102, a flight path storage unit 103, a flight start instruction unit 104, a notification data acquisition unit 121, and a notification data storage unit that the disaster prevention drone 10a does not have. A unit 123 is provided, and in addition to these, an information communication unit 200, a registration information storage unit 201, a flight path generation unit 202, and a hazard map storage unit 203 are provided. The functions having the same names as the parts shown in FIG. 3 are basically the same functions as their corresponding functions (information transfer destinations, operation timings, and the like may differ).

In this embodiment, when the disaster prevention drone 10a is placed in the facility, the person in charge of the placement work performs an operation of registering information about the disaster prevention drone 10a. Specifically, an operation of registering the longest cruising distance of the disaster prevention drone 10a and an operation of registering the arrangement position where the disaster prevention drone 10a is arranged are performed. When the former operation is performed, the distance information indicating the registered maximum cruising distance is supplied to the information communication unit 100. When the latter operation is performed, the position measurement unit 113 of the disaster prevention drone 10a measures the current position as the arrangement position where the own machine is arranged, and supplies the information communication unit 100 with the position information indicating the measured arrangement position.

The information communication unit 100 is a function of communicating information with the server device 20. The information and communication unit 100 transmits the drone registration information in which the drone ID of the own machine is added to the supplied distance information and position information to the server device 20. The information communication unit 200 of the server device 20 is a function of communicating information with each disaster prevention drone 10a. When the information and communication unit 200 receives the transmitted drone registration information, the information and communication unit 200 supplies the received drone registration information to the registration information storage unit 201.

The registration information storage unit 201 stores the supplied drone registration information as registration information of the disaster prevention drone 10a identified by the drone ID indicated by the drone registration information. The flight route generation unit 202 of the server device 20 generates a flight route based on the registration information stored in the registration information storage unit 201 and the hazard map stored in the hazard map storage unit 203. The hazard map storage unit 203 stores a hazard map, that is, a map showing a range (damage prediction area) predicted as a damage occurrence area when an earthquake or the like occurs.

In addition to the damage prediction area, this hazard map includes evacuation shelters (wide area evacuation shelters and evacuation facilities in the event of a tsunami, etc.) and places where people may stay, such as schools, hospitals, parks, and buildings including private houses. Is represented. When new registration information is stored in the registration information storage unit 201, for example, the flight path generation unit 202 has a distance from the arrangement position indicated by the registration information less than a predetermined ratio of the longest cruising distance indicated by the registration information. Extract a certain damage prediction area from the hazard map.

The larger the predetermined ratio is, the more the damage prediction area is extracted from the placement position, but the farther away from the placement position, the shorter the flight distance in the damage prediction area. For example, the flight path generation unit 202 increases the predetermined ratio as the arrangement density of the disaster prevention drone 10a (the number of arrangements per square kilometer, etc.) decreases, so that a distant damage prediction area is extracted. The range covered by the disaster prevention drone 10a may be widened.

In the flight route generation unit 202, the arrangement position indicated by the registration information is set as the departure point and the arrival point, the length is less than the longest cruising distance indicated by the registration information, and the above-mentioned person among the extracted damage prediction areas is used. Generate a flight path that passes as much as possible near where you might stay. For example, the flight route generation unit 202 calculates a plurality of flight routes that pass through the damage prediction area, and the registered information registers the flight route that minimizes the average value of the distances to the places where people may stay. It is generated as a flight path of the disaster prevention drone 10a identified by the indicated drone ID.

The flight route generation unit 202 supplies the flight route storage unit 103 with route information indicating the generated flight route and drone ID. The flight route storage unit 103 stores the supplied route information. So far, the functions related to the registration of the disaster prevention drone 10a have been described. After that, the function of flying the disaster prevention drone 10a when an event causing a disaster occurs will be described.

When the disaster prevention information acquisition unit 101 of the disaster prevention drone 10a acquires the disaster prevention information, the acquired disaster prevention information is supplied to the information communication unit 100. The information and communication unit 100 adds the drone ID of its own machine to the supplied disaster prevention information and transmits it to the server device 20. The information communication unit 100 is an example of the "transmission unit" of the present invention. When the information communication unit 200 of the server device 20 receives the disaster prevention information, the information communication unit 200 supplies the received disaster prevention information to the flight route determination unit 102, the flight start instruction unit 104, and the notification data acquisition unit 121.

The flight route determination unit 102 reads the route information indicating the same drone ID as the supplied disaster prevention information from the flight route storage unit 103, and then uses the same method as in the first embodiment to supply the disaster prevention information, that is, the disaster prevention drone. The flight route to fly in the area indicated by the disaster prevention information transmitted from 10a is determined as the flight route of the disaster prevention drone 10a. The flight path determination unit 102 is an example of the “determination unit” included in the server device of the present invention. The flight route determination unit 102 supplies the route information indicating the determined flight route to the information communication unit 200 and the broadcast data acquisition unit 121.

When the disaster prevention information is supplied, the flight start instruction unit 104 transmits the instruction data instructing the disaster prevention drone 10a that has acquired the disaster prevention information to start the flight via the information communication unit 200, so that the flight is determined. Instruct the disaster prevention drone 10a that has transmitted the disaster prevention information to start the flight on the route. The flight start instruction unit 104 is an example of the "instruction unit" included in the server device of the present invention.

Similar to the embodiment, the notification data acquisition unit 121 acquires a message stored in association with an event that causes a disaster indicated by the supplied disaster prevention information. In addition, the notification data acquisition unit 121 stores a message stored in association with each area of the flight path (each area included in the damage prediction area) determined by the flight path determination unit 102 and an event causing a disaster. get. The broadcast data acquisition unit 121 supplies the acquired message (specifically, voice data indicating the message voice and character string data indicating the message character string) to the information communication unit 100.

The information and communication unit 200 transmits the route information indicating the determined flight route, the instruction data, and the notification data indicating the acquired message to the disaster prevention drone 10a, which is the transmission source of the disaster prevention information. When the route information and the instruction data received by the information communication unit 100 of the disaster prevention drone 10a are supplied to the flight control unit 111, the flight control unit 111 performs flight control in the same manner as in the first embodiment. When the notification data received by the information communication unit 200 is supplied to the notification data holding unit 126, the notification data holding unit 126 holds the notification data.

In addition to the notification data from the server device 20, the notification data holding unit 126 holds in advance sound data indicating the sound of the siren and pattern data of LED blinking as notification data. It should be noted that these broadcast data may be retained as those transmitted from the server device 20. The notification unit 122 reads the notification data from the notification data holding unit 126 during the flight of the own aircraft, and similarly to the first embodiment, notifies the disaster related to the disaster indicated by the disaster prevention information acquired by the disaster prevention information acquisition unit 101.

FIG. 11 shows an example of an operation procedure in the notification process of this embodiment. This operation procedure is started when an event that causes a disaster occurs and disaster prevention information is provided. First, the disaster prevention drone 10a (disaster prevention information acquisition unit 101) acquires disaster prevention information (step S31). Next, the disaster prevention drone 10a (information and communication unit 100) transmits the acquired disaster prevention information to the server device 20 (step S32). The server device 20 (flight route determination unit 102) determines a flight route to fly in the disaster area indicated by the transmitted disaster prevention information (step S33).

Subsequently, the server device 20 (notification data acquisition unit 121) acquires the message stored in association with the event causing the disaster indicated by the transmitted disaster prevention information as the notification data (step S34). Further, the server device 20 (notification data acquisition unit 121) acquires a message stored in association with each area on the flight path determined in step S33 as notification data (step S35). Next, the server device 20 (flight start instruction unit 104) generates instruction data instructing the start of flight (step S36).

Then, the server device 20 (information and communication unit 200) transmits the route information indicating the determined flight route, the acquired notification data, and the generated instruction data to the disaster prevention drone 10a (step S37). The disaster prevention drone 10a (notification data holding unit 126) holds the transmitted notification data (step S38). The disaster prevention drone 10a (flight control unit 111) starts flight control of the flight along the flight path indicated by the transmitted route information (step S41). Next, the disaster prevention drone 10a (position measuring unit 113) measures the current position of the own machine (step S42).

Subsequently, the disaster prevention drone 10a (notification data acquisition unit 121) acquires a message held in the own machine (notification data holding unit 126) in association with the area including the measured current position (step S43). Next, the disaster prevention drone 10a (notification unit 122) notifies about the disaster based on the notification data held in step S38 and the notification data acquired in step S43 (step S44). Then, the disaster prevention drone 10a determines whether or not it has returned to the facility where its own aircraft was located (step S45), and if it determines that it has not returned (NO), it returns to step S41 and continues the operation. If it is determined that the player has returned (YES), this operation procedure is terminated.

Also in this embodiment, the evacuation of people in the disaster-stricken area (damage prediction area) can be promoted as compared with the case where the disaster prevention drone 10a does not notify about the disaster. Further, in this embodiment, since the server device 20 performs the flight route determination process and the notification data acquisition process, the load of the process performed by the disaster prevention drone is reduced as compared with the case where the disaster prevention drone performs these processes. be able to.

[3] Modification Example The above-described embodiment is merely an example of the embodiment of the present invention, and may be modified as follows.

[3-1] Time zone The flight route that the disaster prevention drone flies may differ depending on the time zone. In this modification, the flight path storage unit 103 stores a plurality of flight paths associated with a plurality of events causing a disaster in association with each of a plurality of time zones.

FIG. 12 shows an example of the route information stored in this modified example. In the example of FIG. 12, the flight path storage unit 103 refers to "tsunami", "flight path R1-1", "landslide", and "flight path R2-1" in association with the time zone "weekday daytime". It stores events and route information that cause two sets of disasters. Although the route information is simply represented in FIG. 12 for the sake of clarity, it is assumed that the route information is actually represented by a set of latitude and longitude as in the example of FIG.

Similarly, the flight path storage unit 103 has two sets of "tsunami" and "flight path R1-2", "landslide" and "flight path R2-2" in association with the time zone of "weekday night, holiday night". Events and route information are memorized, and two sets of events, "tsunami" and "flight route R1-3", "landslide" and "flight route R2-3", are associated with the time zone of "holiday daytime". Stores route information.

For example, in the case of the area shown in FIG. 1, as the "flight route R1-1" associated with "weekday daytime", a flight route including a route that goes around the school C1 where people gather during weekday daytime is used. Be done. In addition, "flight route R1-2" and "flight route R2-2" associated with "weekday night, holiday night" are used for flight routes that focus on areas with private houses with people at night. Be done. Further, as the "flight route R1-3" associated with the "holiday daytime", a flight route including a route for flying around the coast and the park where people gather during the holiday daytime is used.

The flight route determination unit 102 determines the flight route stored in association with the event indicated by the acquired disaster prevention information and the current time zone. For example, when disaster prevention information indicating a tsunami warning is acquired during the daytime on weekdays, the flight path determination unit 102 stores the “flight path R1-1” in association with the “daytime on weekdays” and the “tsunami”. Is determined as the flight route of the disaster prevention drone 10. Further, when the area mail indicating the landslide is acquired at night on a holiday, the flight route determination unit 102 disaster-prevents the "flight route R2-2" stored in association with the "holiday night" and the "landslide". Determined as the flight path of the drone 10.

In the damage prediction area, the place where people gather may differ depending on the time of day. For example, during the daytime on weekdays, people gather in schools and office districts, and during the daytime on holidays, people gather in places to play such as beaches, parks, and amusement parks. In addition, there are people in sleeping places such as private houses and hotels at night. In this modification, the flight path associated with the time zone is determined. Therefore, by using the flight path that passes through the place where people gather in each time zone, the flight path is uniform even if the time zone is different. In comparison, it is possible to inform more people about the disaster.

[3-2] Temporary flight route In the example, the disaster prevention drone flew along the determined flight route, but when a person or vehicle is found in a place away from the flight path, a temporary flight to that place is temporary. Flight paths may be used. The vehicle referred to here is, for example, a car or a motorcycle, and is a vehicle on which a person rides and moves.

FIG. 13 shows the functional configuration realized by the disaster prevention drone 10b of this modified example. The disaster prevention drone 10b includes a person / vehicle detection unit 105 in addition to the units shown in FIG. The person / vehicle detection unit 105 detects the location of at least one of the person or the vehicle. The person / vehicle detection unit 105 is an example of the "detection unit" of the present invention. In the disaster prevention drone 10b, the sensor device 16 is equipped with, for example, an image pickup device, and the person / vehicle detection unit 105 determines whether or not a person or vehicle is captured from the image taken by the image pickup device using pattern recognition technology or the like. To do.

When the person / vehicle detection unit 105 determines that a person or a vehicle is in the image, the distance from the position where the object is shown in the image, the current flight altitude, and the direction in which the aircraft is facing to the object. And determine the direction. The person / vehicle detection unit 105 supplies the flight control unit 111 with target information indicating the distance and direction to the determined target. When the above-mentioned target location is detected during flight of the flight path, the flight control unit 111 controls to fly to that location and then return to the flight path.

For example, when the target information is supplied, the flight control unit 111 is detected by changing the direction of the own aircraft in the direction indicated by the target information and flying the own aircraft in that direction by the distance indicated by the target information. Make your aircraft reach the target location. When the flight control unit 111 reaches the target location, for example, the flight control unit 111 reverses the direction of the aircraft by 180 degrees and flies the aircraft until it returns to the flight path. Due to this control, the flight path to which the disaster prevention drone 10b flies is a temporary flight path to temporarily fly to the detected target location.

In the above example, the flight path itself was not changed, but the person / vehicle detection unit 105 supplies the target information to the flight path determination unit 102, and the flight path determination unit 102 makes a new flight including a temporary flight path. A route may be generated, the original flight route may be discarded as the flight route of the disaster prevention drone 10b, and a new flight route may be determined. Even in this case, the flight control unit 111 controls to return to the flight path after flying to the target location.

The flight path is set to pass as close as possible to where people are likely to be, so that as many people as possible are notified of the disaster. However, for example, even if the flight route to fly around the school is decided, if the students happen to be a little away from the school in extracurricular lessons, they will fly only on the decided flight route. It is possible that the students in the school cannot be notified. In this modification, even if the location is far from the flight path, if the location of the person or vehicle is detected as described above, the disaster prevention drone 10b will fly to that location and notify the disaster. As a result, it is possible to make it easier for people in unexpected places to be notified of the disaster as compared with the case where they do not fly on the temporary flight path.

Further, the flight control unit 111 controls to fly the above-mentioned temporary flight path when the round-trip distance to the detected target location is shorter than the difference between the longest cruising distance of the own aircraft and the flight path. May be good. As a result, it is possible to prevent the battery from running out and being unable to return due to flying on the temporary flight path.

Further, when the person / vehicle detection unit 105 determines that the vehicle is shown in the image, the person / vehicle detection unit 105 may detect the location of the vehicle only when the vehicle is moving. For example, the person / vehicle detection unit 105 repeatedly determines whether or not a person or a vehicle is in the image at regular time intervals, and changes the direction and distance of the vehicle that is determined to be in the image as seen from the vehicle itself. , Judge whether the vehicle is moving or not from the flight direction and flight speed of the own aircraft.

When the person / vehicle detection unit 105 determines that the vehicle is moving, the person / vehicle detection unit 105 detects the location of the vehicle. As a result, for example, abandoned and stopped vehicles will not be detected, so they will fly on a temporary flight path toward an unoccupied vehicle, and the remaining flight path will be compared to when flying straight on the original flight path. You can prevent delays in communicating disaster notifications to people around you.

The temporary flight route does not have to be a reciprocating route as in the above example. For example, the flight control unit 111 flies its own aircraft to a target location detected from a certain point on the determined flight path, arrives at the target location, and then returns to the original flight path through a route different from the route taken. Control the flight so that it flies on the return route. In that case, the flight control unit 111 performs flight control so as not to cut a part of the original flight path and pass through. As a result, it is possible to reduce the delay caused by flying on the temporary flight route as compared with the case where the temporary flight route reciprocating on the same route is used.

[3-3] Occurrence of new events After the disaster prevention drone departs, new events such as earthquakes may occur. For example, when a tsunami occurs after departing for a disaster area due to the occurrence of an earthquake, or when a landslide occurs after departing for a disaster area due to a flood caused by heavy rain. In that case, the flight route may be changed so that the disaster prevention drone flies in the damage prediction area due to the new event.

In this modification, when the flight path determination unit 102 acquires disaster prevention information about a disaster caused by an event different from that before the flight during the flight of the determined flight path by the disaster prevention information acquisition unit 101, the disaster prevention Determine the flight path to fly in the area indicated by the information. The determination of this new flight path may be made in the same manner as in the embodiment. Then, the flight control unit 111 controls the flight along the flight path newly determined by the flight path determination unit 102.

By controlling the flight control unit 111 to switch the flight path in this way, for example, the flight of the new flight path can be performed as compared with the case where the disaster prevention drone 10 departs again after returning and flies on the new flight path. You can start earlier. The flight control unit 111 may determine whether or not to switch the flight path when a new flight path is determined. The flight control unit 111 stores a predetermined priority for an event such as an earthquake.

When the flight control unit 111 has a higher priority of the event indicated by the disaster prevention information used for determining the new flight route than the priority of the event indicated by the disaster prevention information used for determining the flight route currently in flight. In addition, the flight route is switched. As a result, the notification regarding the disaster in the event that has occurred can be prevented from being interrupted in the middle due to the occurrence of an event having a lower priority than that.

The method of determining the priority is not limited to this. The flight control unit 111 has a higher priority, for example, the one with a wider damage prediction area indicated by the acquired disaster prevention information (determined by comparing the area of the target area or the number of local public bodies included in the disaster area). You may judge that. In that case, if an event with a wider damage prediction area newly occurs, the flight route will be switched. As a result, it is possible to prevent the notification of the disaster in the event that has occurred from being interrupted in the middle due to the occurrence of the event whose damage prediction area is narrower than that of the event.

[3-4] Notification method As described in the embodiment, the notification unit 122 may perform a plurality of notification methods (a method of outputting a message voice, a method of outputting a siren sound, a method of displaying a message character string, and a method of displaying a message character string. , Both have a method of blinking the LED). Since the power consumption is too large when all of these plurality of notification methods are always used, the notification unit 122 may change the notification method to be used depending on the situation.

The notification unit 122 uses, for example, a notification method table in which the priority of notification and the notification method in each area on the flight path are associated with each other. The priority of notification means that the higher the priority of the area, the higher the need to convey the content of notification to people. For example, in the case of a riverbed area and a densely populated area, the densely populated area has a higher priority for notification.

FIG. 14 shows an example of the notification method table. In the example of FIG. 14, if the priority of the notification method is "1", "message voice + message character string + LED" is set as the notification method, and if the priority of the notification method is "2", "message voice + message character". The "column" is used as the notification method, and if the priority of the notification method is "3", the "message voice" is used as the notification method. The priority of notification is predetermined for each flight path stored in, for example, the flight path storage unit 103.

FIG. 15 shows an example of the priority of notification defined for the flight path. In FIG. 15, the priority of notification defined for the flight path R1 shown in FIG. 1 is shown. In the flight route R1, the priority outside the damage prediction area from the departure point to the tsunami damage prediction area A1 and from the tsunami damage prediction area A1 to the arrival point is set to "3". In addition, the priority of the school area around the school C1 and the densely populated residential area is set to "1", and the priority of the coastal area is set to "2".

The priority for each area is determined in advance by the operator of the disaster prevention drone, for example, and the priority data indicating the priority is stored in the disaster prevention drone. The method of setting priorities for each area is not limited to this. For example, the disaster prevention drone stores map data in which priorities are set in advance for each area as area information on the map, and after the flight route is determined, for example, the notification unit 122 determines the determined flight route. The priority set for the area overlapping with the above-mentioned area information may be extracted from the map data and set as the priority for those areas.

In the example of FIG. 15, in the tsunami damage prediction area A1, it is determined that the higher the density of people in each area on the flight route R1, the higher the priority of notification (school area, densely populated area). Is more crowded than in overseas areas). In addition, it is stipulated that the area inside the tsunami damage prediction area A1 has a higher priority than the area outside the tsunami damage prediction area A1. Using the notification method table shown in FIG. 14, the notification unit 122 outputs a message voice and a message character string associated with the priority "2", for example, when flying in a coastal area on the flight path R1. Notify about disasters.

Further, when flying in a school area or a densely populated residential area on the flight path R1, the notification unit 122 outputs a message voice and a message character string associated with the priority "1", and blinks the LED to cause a disaster. Notify about. In this way, the notification unit 122 notifies the disaster in the tsunami damage prediction area A1 by using as many methods as when flying in an area having a high priority of notification.

As a result, in the area where the priority of the notification is high, the content of the notification can be easily transmitted to more people than in the area where the priority of the notification is low. Further, in this modification, the higher the density of people, the higher the priority of notification, so that the notification content can be easily transmitted to more people in the area where more people are present. As a result, more people in the damage prediction area will be notified about the disaster by making more effective use of the limited power of the disaster prevention drone 10 compared to the case where the priority is set without considering the density of people. Can be told to.

The factor used when determining the priority of notification in each area is not limited to the degree of crowding of people. For example, an area where it is difficult to evacuate because there are few evacuation sites may be given higher priority than an area where evacuation sites are close and easy to evacuate even if people are crowded (priority). Factors that determine the degree = difficulty of evacuation). For the same reason, areas where people who take time to evacuate, such as the elderly, children and the sick, are gathered (elementary schools, elderly housing with care and hospitals, etc.) may be given higher priority than other areas.

In addition, the priority of an area with a highly public building or the like may be higher than that of another area (factor for determining priority = public). In addition, the priority of the area where the sound of the disaster prevention radio does not reach may be higher than that of other areas (the factor that determines the priority = the sound propagation of the disaster prevention radio). In addition, two or more of these factors (population of people, difficulty in evacuation, publicity, sound propagation of disaster prevention radio) are represented by points, and the area with the larger total points has priority. May be higher. In either case, it is desirable to promote the evacuation of people by making more effective use of limited electricity by giving higher priority to areas where there are people who want to convey disaster notifications more reliably.

[3-5] Flight Start Instruction In the first embodiment, the disaster prevention drone 10 instructed the own aircraft to start the flight, and in the second embodiment, the server device 20 instructed the flight start. Not exclusively. For example, in the second embodiment, the disaster prevention drone 10 may instruct the own aircraft to start flight. Further, instead of the device, a person such as an operator may operate the disaster prevention drone 10 or the server device 20 to instruct the start of flight.

For example, a firefighter at a fire department sends information indicating a fire point, an affected area, and an event (fire) that causes a disaster to the server device 20 using a communication terminal such as a smartphone, and instructs the server device 20 to start the flight. May be good. In addition, when an avalanche occurs in a snowy mountain, firefighters send information indicating the area affected by the avalanche and the event (avalanche) that causes the disaster to the server device 20 using a communication terminal such as a smartphone, and fly. You may instruct to start.

[3-6] Generation of flight path In the second embodiment, the flight path generation unit 202 of the server device 20 has generated the flight path in advance, but the present invention is not limited to this, and for example, flight is performed after disaster prevention information is acquired. The route generation unit 202 may generate a flight route in real time. By doing so, it is possible to generate a flight route based on the latest drone registration information and the latest hazard map. Further, the disaster prevention drone may include a flight route generation unit 202 and a hazard map storage unit 203, and generate a flight route based on the damage prediction area represented by the hazard map.

Further, in the second embodiment, the damage prediction area shown in the hazard map was used, but the present invention is not limited to this. For example, the range of the damage prediction area indicated by the disaster prevention information may differ depending on the scale of the event that causes the disaster (for example, the number of areas included in the damage prediction area differs). It is possible to generate a flight path in advance assuming a disaster of any scale, but there is still a possibility that a disaster of an unexpected scale will occur.

Therefore, the flight route generation unit 202 identifies the damage prediction area indicated by the acquired disaster prevention information, and extracts a disaster prevention drone in which the distance from the placement position to the specified damage prediction area is less than a predetermined ratio of the longest cruising distance. .. The flight path generation unit 202 then generates a flight path by the method described in the second embodiment. In this way, the flight path generation unit 202 generates a flight path for flying in the specified damage prediction area as the flight path of the extracted disaster prevention drone.

In this way, the flight path generation unit 202 generated the flight path for each disaster prevention drone in the second embodiment, but in this embodiment, the flight path is generated in real time for each damage prediction area indicated by the disaster prevention information. As a result, a flight route suitable for the scale and location of the disaster is generated, so that it is possible to notify the disaster in an area where more evacuation is required, as compared with the case where only the flight route prepared in advance is used.

[3-7] Flight Path Generation Method The flight path generation method is not limited to the above-mentioned method. For example, the flight path generation unit 202 may specify a place where a person is present at the current time from big data and generate a flight path passing through the specified place. In addition, the flight route generation unit 202 identifies the residential location included in the damage prediction area from the map data reflecting the residential location described in the Basic Resident Register on the map, and generates a flight route passing through the specified residential location. You may.

Further, the flight path generation unit 202 may specify a building included in the damage prediction area from map data indicating the position of a building such as a house, and generate a flight path passing through the position of the specified building. Further, the flight path generation unit 202 may estimate a building from the map data of the aerial photograph and generate a flight path passing through the estimated position of the building. In addition, the flight route generation unit 202 may memorize the locations of evacuation shelters, public buildings, parks, and leisure spots, and generate flight routes that pass through those locations included in the damage prediction area.

In addition, the flight route generation unit 202 identifies the positions of those households included in the damage prediction area from the map data showing the positions of the single-living households as the information collected from the neighborhood association by the local public body, and the positions of the specified households. You may generate a flight path through. Further, the flight path generation unit 202 may specify those areas included in the damage prediction area from the data indicating the areas where the sound of the disaster prevention radio does not reach, and generate a flight path passing through the specified areas.

In addition, the flight route generation unit 202 identifies the no-fly zone included in the damage prediction area from the data indicating the no-fly zone (near the airport, etc.) that is prohibited by the Aviation Law, and passes through the specified no-fly zone. No flight path may be generated. Further, the flight path generation unit 202 determines whether or not the current time is flight prohibited from the data indicating the time zone when the flight path is prohibited from flying, and if it is determined that the flight is prohibited, the flight prohibited area is determined. A flight path that does not pass is generated, and if it is determined that the flight is not prohibited, a flight path that passes through the no-fly zone is generated.

Further, the flight path generation unit 202 acquires the notification status (via the information communication unit) indicating the notified position from the notification unit 122 and the position measurement unit 113, and the disaster prevention information acquisition unit 101 newly acquires the disaster prevention information. If so, a flight path may be generated through the notified position indicated by the acquired notification status.

In addition, the flight route generation unit 202 has a place where the contents of the notified disaster prevention information (disaster prevention information that is the source of the notification) and the new disaster prevention information do not change among the flight routes that have been notified by the disaster prevention drone. In that case, a new flight path may be generated under the condition that the airspace excluding the place is covered. Further, the flight path generation unit 202 may generate a flight path by combining the information used in the above-described flight path generation method.

[3-8] Area message DB
The evacuation site may differ depending on the scale and combination of events that cause the disaster. Therefore, the notification data storage unit 123 may store, for example, the area message DB 125 in which the scale and combination of events that cause a disaster, the evacuation site, and the message are associated with each other.

FIG. 16 shows an example of information at a certain location stored in the area message DB 125 of this modification. In the example of FIG. 16, for the events that cause disasters such as "earthquake (seismic intensity less than 6)" and "earthquake (seismic intensity 6 or more)", evacuation sites such as "temporary evacuation site" and "wide area evacuation site" are used. The messages "Schools, parks, and public halls are temporary evacuation sites" and "School C1 is a wide area evacuation site." Are associated with each other.

In addition, for events that cause disasters such as "tsunami (less than 1 m)" and "tsunami (1 m or more)", there are evacuation sites such as "none" and "elevation / tsunami evacuation facility" and "Keep away from the coast". The messages "Please." And "Please evacuate to M2 Mountain, Tsunami Evacuation Facility C2 or a nearby hill." Are associated with each other. In addition, the tsunami evacuation facility C2 is designed to withstand a combination of disaster-causing events such as "earthquake (seismic intensity 6 or higher) and tsunami (1 m or higher)" and is damaged by the earthquake. The evacuation site "elevation" is associated with the message "Please evacuate to M2 mountain or a nearby hill."

The notification data acquisition unit 121 acquires the event that causes the disaster indicated by the acquired disaster prevention information and the message stored in association with the scale thereof. This makes it possible to deliver a message regarding an evacuation site that matches the scale and combination of events that cause a disaster. If events such as "earthquake (seismic intensity less than 6)" and "tsunami (1 m or more)" that do not have a specified combination occur together, the priority is set in advance for each event and the notification data The acquisition unit 121 acquires a message stored in association with the event having the higher priority.

Further, in addition to the flight path generation method described in the above modification, even if the flight path generation unit 202 generates a flight path passing through an evacuation site determined according to the scale and combination of events that cause a disaster. Good. This makes it possible to send a message calling for evacuation to the evacuation site while flying the disaster prevention drone near the evacuation site that matches the scale and combination of events that cause the disaster.

[3-9] Flight Distance The flight path generation unit 202 may generate a flight path based on the flight distance until the return flight. For example, the flight path generation unit 202 selects and generates the flight path having the shortest flight distance when the flight path is generated by each of the above-mentioned plurality of generation methods. Further, in this modification, it is assumed that the disaster prevention drone is provided with the person / vehicle detection unit 105 and the information / communication unit 100, and the server device 20 is provided with the flight path generation unit 202 and the like.

In the above modification, the person / vehicle detection unit 105 shown in FIG. 13 detects the location of a person or vehicle, but the round-trip distance to the detected target location is based on the difference between the maximum cruising distance of the aircraft and the flight path. If it is too short, the above modified example did not fly on the temporary flight path because the battery may run out. In this modification, in that case, the flight control unit 111 performs flight control to fly the temporary flight path, and the information and communication unit 100 flies the flight path, the current position, and the remaining flight path to another disaster prevention drone. Request data indicating the request to be received is transmitted to the server device 20.

When the flight path generation unit 202 of the server device 20 receives this request data, there is a disaster prevention drone capable of flying the remaining flight path from the arrangement position of the disaster prevention drone indicated by the registration information stored in the registration information storage unit 201. Judge whether or not. When the flight path generation unit 202 has a flightable disaster prevention drone and the flight start instruction unit 104 does not issue a flight start instruction to the disaster prevention drone, the flight path generation unit 202 uses the position of the disaster prevention drone as the departure point and the arrival point. Generate a flight path that includes the remaining flight paths mentioned above.

By flying the disaster prevention drone along the flight path generated in this way, it is possible to notify the person in the place where the disaster prevention drone that was flying earlier is detected, and the disaster prevention drone further performs. Notifications on the remaining flight routes that were planned can also be provided by another disaster prevention drone.

[3-10] Flight Speed and Flight Altitude The flight control unit 111 may fly in the area at the flight speed and flight altitude (height from the ground) determined for each area on the flight path. For example, in an area with a large number of people, an area with low sound transmission, or an area with low visibility in the sky (such as a densely populated area), the flight speed is slowed down and the flight altitude is lowered, and the notification content is people in the area. Make it easy to communicate to. If the flight altitude is too low, it may collide with obstacles. Therefore, the minimum flight altitude may be set for each area and the flight may not be lower than that.

On the other hand, in areas where there are few people, areas with high sound transmission, or areas with high visibility over the sky (coastal areas, etc.), the flight altitude is increased so that the notification content can be transmitted to people who are far away, while increasing the flight speed. Make it faster so that notifications in the next area will be made earlier. The flight speed and flight altitude may be determined when the flight path generation unit 202 generates the flight path. In that case, the flight path generation unit 202 generates a flight path, determines the flight speed and flight altitude in each area on the flight path, and stores the route information indicating the flight path, flight speed, and flight altitude in the flight path storage unit. Store in 103.

The flight path generation unit 202 stores map data including information on the terrain, buildings, and the like, and determines the density of people, sound transmission, or the outlook in the sky from the terrain, the density of buildings, and the like. For example, in residential areas and in the city, the density of people is high, and the sound transmission and the visibility of the sky are low (this tendency increases as the buildings are denser). Along the coast, the density of people is low, and the sound transmission and the visibility of the sky are high. On the other hand, in the mountains and forests, the density of people, the sound transmission, and the visibility of the sky are all low.

The flight path generator 202 further provides a data table that represents the relationship between the flight altitude, the sound transmissibility at that location (terrain, building density, residential area, city), and the distance that sound can be transmitted. I remember. The flight path generation unit 202 uses this table to generate a flight route in consideration of sound transmission at the notification point, thereby determining a faster flight speed and a higher flight altitude in an area having higher sound transmission. ..

By determining the flight speed and flight altitude in this way, the flight path generator 202 determines the flight speed and the flight altitude, so that even if an unexpected flight path is generated, the notification content can be easily transmitted as described above, and the notification content can be transmitted to a person who is far away. Alternatively, the disaster prevention drone can be flown at a flight speed and altitude at which the next area is notified earlier.
