FIG. 4 is a diagram showing an example of the functional configuration of the server device 30. In the server device 30, the functions of the acquisition section 31, the storage section 32, the mesh extraction section 33, the flight route determination section 34, and the output section 35 are realized by the cooperation of each of the hardware described above.

The acquisition unit 31 is a means for acquiring information from outside the server device 30, and acquires, for example, disaster prevention information indicating the occurrence of an event that causes a disaster and the area affected by the disaster. The acquisition unit 31 also acquires information regarding the drone (for example, the position, speed, altitude, remaining power amount, or other operating status of the drone 10) from each drone 10.

The mesh extraction unit 33 extracts a plurality of meshes that cover the area targeted for notification regarding the disaster indicated by the disaster prevention information and have different sizes depending on conditions. Here, the mesh refers to each small area when a wide area such as all of Japan is divided into small areas of a certain size and a certain shape. This mesh has a plurality of sizes, and in this embodiment, three types of meshes are assumed: the smallest small mesh, the largest large mesh, and a medium mesh that is an intermediate size between the small mesh and the large mesh. For example, a small mesh is a rectangle with sides ranging from several meters to several tens of meters, a medium mesh is a rectangle with sides ranging from several tens of meters to several hundred meters, and a large mesh is a rectangle with sides ranging from several hundred meters to several kilometers. However, it is not necessarily limited to this example. Note that in this embodiment, the small mesh, medium mesh, and large mesh all have the same rectangular shape, but the shape of the mesh may be other than rectangular or may be different depending on the size of the mesh. . Furthermore, the size of the mesh is not limited to the three types illustrated in this embodiment, but may be at least two or more types.

FIG. 5 is a diagram illustrating the relationship between the mesh size of the small mesh and the notification area by the drone 10. In FIG. 5, when the drone 10 is at the center of the small mesh M1 (a position corresponding to the center of gravity of the rectangle), the notification area A1 is the range in which humans within the small mesh M1 can recognize notifications from the drone 10. . In other words, in the small mesh M1, the drone 10 outputs (emits) a message sound calling for evacuation from the speaker at a low volume that can reach the notification area A1 including the small mesh M1, or a message text calling for evacuation. Notification is performed by outputting (displaying) images of the lines on a display, or outputting (emitting) light from an LED to attract attention to the message sounds and message character strings. That is, the drone 10 provides notification regarding a disaster in a small mesh using message audio, video, and LEDs that are suitable for transmitting information over a relatively short distance.

FIG. 6 is a diagram illustrating the relationship between the mesh size of the medium mesh and the notification area by the drone 10. In FIG. 6, when the drone 10 is located at the center of the medium mesh M2 (a position corresponding to the center of gravity of the rectangle), the notification area A2 is the range in which a person within the medium mesh M2 can recognize notifications from the drone 10. . In other words, in the medium mesh M2, the drone 10 outputs (emits) a message sound from the speaker at a medium volume that can reach the notification area A2 including the medium mesh M2, or draws attention to the message sound. It provides notifications such as outputting (emitting) light from an LED to turn on the device. In other words, the drone 10 uses a message voice and an LED suitable for transmitting information over a medium distance in a medium mesh to notify disaster-related information.

FIG. 7 is a diagram illustrating the relationship between the mesh size of the large mesh and the notification area by the drone 10. In FIG. 7, when the drone 10 is located at the center of the large mesh M3 (position corresponding to the center of gravity of the rectangle), the range in which humans within the large mesh M3 can recognize notifications from the drone 10 is defined as the notification area A3. There is. In other words, in the large mesh M3, the drone 10 outputs (emits) a message sound from the speaker at a volume high enough to reach the notification area A3 that includes the large mesh M3, or draws attention to the message sound. It provides notifications such as outputting (emitting) light from an LED to turn on the device. In other words, the drone 10 provides notification regarding a disaster in a large mesh using a message sound suitable for transmitting information over a relatively long distance.

FIG. 8 is a diagram illustrating changes in mesh size in the same area. As illustrated in FIG. 8, when the drone 10 makes a notification in the same area, a mesh of an appropriate size is determined according to various conditions, and the flight path of the drone 10 is determined in units of meshes. More specifically, the size of the mesh varies depending on the method by which the drone 10 makes a disaster notification, the density of people, or the day or time when the drone 10 makes a disaster notification.

In order to determine the mesh size, the storage unit 32 stores mesh size determination tables as illustrated in FIGS. 9 to 11. FIG. 9 illustrates a mesh size determination table for determining the mesh size according to the notification method by which the drone 10 performs notification. As illustrated in FIG. 9, a small mesh is adopted when the notification method α (for example, notification using message voice, video, and LED suitable for information transmission over a relatively short distance) is used, and a small mesh is used when the notification method β (for example, a medium When the notification method is γ (for example, notification using a message sound suitable for information transmission over a relatively long distance), medium mesh is adopted. is now using a large mesh. Depending on the disaster prevention information acquired by the acquisition unit 31 and the specifications of the drone 10, the notification method for the drone 10 to notify may be determined. The mesh size is determined.

FIG. 10 illustrates a mesh size determination table for determining the mesh size according to the density of people. As illustrated in Figure 10, when the density is high (for example, the population density per square kilometer is more than the threshold th1), from the perspective of reducing the number of people who can be notified within one mesh to ensure reliable notification. A small mesh is adopted, and when the density is medium (for example, the population density per square kilometer is greater than or equal to threshold th2 and less than threshold th1, threshold th2 < threshold th1), a medium mesh is adopted, and when the density is small (for example, the population per square kilometer is When the density is less than the threshold th2), a large mesh is used. As described above, the disaster prevention information acquired by the acquisition unit 31 indicates an area affected by a disaster, so the mesh size is determined according to the density of people (population density) in this area.

FIG. 11 illustrates a mesh size determination table for determining the mesh size according to the time period. As illustrated in FIG. 11, a small mesh is adopted from the viewpoint of reliably informing even people who are sleeping during time period X (for example, 24:00 to 4:00), and 4:00 to 6:00 and 21:00 to 24:00), medium mesh is used, and during time zone Z (for example, 6:00 to 21:00), large mesh is used. There is. As described above, the disaster prevention information acquired by the acquisition unit 31 indicates the occurrence of an event that causes a disaster, so the mesh size is determined according to the time of occurrence.

Note that the mesh size may be determined using a table that is a combination of the mesh size determination tables shown in FIGS. 9 to 11 described above. For example, if any one of the conditions of notification method α, high density, or time zone X is satisfied, a small mesh is adopted, or if all the conditions of notification method α, high concentration, and time zone X are satisfied For example, a small mesh may be used if the notification method α is used and the density is high. In other words, the correspondence relationship between the mesh size and the sufficiency of each condition such as the method of the drone 10 reporting, the density of humans, or the day or time the drone 10 reports disaster prevention information can be determined arbitrarily. Can be done.

Furthermore, as illustrated in FIG. 12, the storage unit 32 stores mesh data such as the position of each mesh and in which mesh disaster prevention information is to be reported when disaster prevention information is acquired. There is. In the example of FIG. 12, the inclusion relationship of the small mesh, medium mesh, and large mesh in the same region is defined by associating mesh IDs that are identification information of the small mesh, medium mesh, and large mesh. For example, a medium mesh with mesh ID "M00001" includes small meshes with mesh IDs "S00001" to "S00004".

As for the position of the mesh, the center position of the small mesh is expressed by latitude and longitude, for example. The positions of the medium mesh and the large mesh can be calculated from the center position of the small mesh described above, as well as the size of each mesh and the inclusion relationship of each mesh.

In FIG. 12, the small meshes with mesh IDs "S00001" to "S00003" are used to identify the disasters indicated by the disaster prevention information when the disaster prevention information indicating the occurrence of the event that causes disaster A and the area affected by the disaster is acquired. This is the mesh where notifications are made. In this case, the medium mesh with mesh ID "M00001" and the large mesh with mesh ID "B00001" that include at least one of the small meshes with mesh IDs "S00001" to "S00003" are also responsible for the event that causes disaster A. When disaster prevention information indicating the occurrence and area affected by the disaster is acquired, it becomes a mesh in which notifications regarding the disaster indicated by the disaster prevention information are made.

Returning to the explanation of FIG. 4, the flight route determination unit 34 determines a flight route that includes the order in which the drone 10, which provides notification regarding a disaster indicated by the disaster prevention information, flies over the plurality of extracted meshes. Particularly in this embodiment, the flight route determination unit 34 determines the flight route of each of the plurality of drones 10 . At this time, the flight route determining unit 34 determines a flight route for each of the drones 10 that includes the order in which the multiple drones 10 fly through the extracted meshes without overlapping. In the example of Figure 12, when disaster prevention information indicating the occurrence of an event that causes disaster A and the area affected by the disaster is acquired, and the mesh size is determined to be a small mesh based on the conditions described above, the mesh A flight path passing through the positions of small meshes with IDs "S00001", "S00002", "S00003"... will be determined, and if the mesh size is determined to be a medium mesh, then mesh IDs "M00001", "M00002"... A flight path that passes through the medium mesh position will be determined, and if the mesh size is determined to be a large mesh, a flight path that passes through the large mesh position with mesh ID "B00001"... It turns out.

The output unit 35 outputs the flight route determined by the flight route determining unit 34 as well as broadcast information indicating the content to be broadcast by the drone 10 to the drone 10 via the communication network 20. The drone 10 performs flight control based on its own position, altitude, and attitude along the output flight path. The notification device 10061 of the drone 10 then provides notification regarding a disaster based on the output notification information. For example, when the notification information includes voice data indicating a message voice calling on people to evacuate, the notification device 10061 emits the message voice from a speaker to send a message informing people of the need to evacuate during a disaster. This will be done as a notification regarding. For example, for an event that causes a disaster, such as an "earthquake," a message might read, "An earthquake has occurred. Once the shaking has subsided, please evacuate to a nearby wide-area evacuation site." Similarly, the events that cause disasters such as ``tsunami'', ``landslide'', and ``fire'' are accompanied by ``There is a risk of a tsunami. Please move away from the coast or evacuate to higher ground.'' and ``There is a risk of a landslide.'' Messages such as ``Please move outside the landslide warning area.'' and ``A fire has broken out. Please exit the building and evacuate as there is a risk of the fire spreading.'' Both are messages calling for evacuation in order to avoid disaster when each event occurs. Since the evacuation method differs depending on the event that occurred, the message also differs depending on the event.

Further, it is assumed that, for example, a local government or the like has determined the sound of a siren to be sounded when an event that causes a disaster occurs, and residents are also made aware of this. In that case, if sound data indicating the sound of the siren is included in the notification information, the notification device 10061 can emit the siren sound indicated by the notification data from the speaker to prevent the occurrence of events that may cause a disaster. Disaster announcements are made to inform people that a disaster has occurred. In addition, for example, when the notification information includes character string data indicating a message character string urging people to evacuate, the notification device 10061 displays the message character string indicated by the notification information on the display to remind people of the need to evacuate. Disaster announcements will be made to notify people of the disaster. The notification device 10061 makes this notification while the own aircraft is in flight under the flight control performed by the flight device 1009. This makes it possible to notify people in the predicted damage area about the disaster. Further, when the notification information includes pattern data indicating a blinking pattern of the LED, the notification device 10061 causes the LED to blink in the blinking pattern indicated by the notification information. The notification device 10061 flashes the LED together with other notifications. As a result, even people who are far away from the drone 10 and cannot hear the output sound or see the image of the displayed message string can see the blinking of the LED from a distance, so they can approach the drone 10 and hear the sound. You can encourage them to check the video. Furthermore, if a person in the direction of travel of the drone 10 notices the flashing LED first, he/she will pay attention to the drone 10 and will be more likely to notice the message voice etc. when the drone 10 approaches. In this way, the notification device 10061 can increase the effectiveness of notification regarding disasters by blinking the LED.

By the way, the time required to fly each flight route determined for each drone 10 by the flight route determining unit 34 depends on, for example, the size of the mesh that is the unit when determining the flight route, the flight ability of each drone 10, Or, it varies depending on the weather such as wind and rain. Therefore, for example, even if one drone 10 finishes flying for disaster notification, other drones 10 may still continue flying for disaster notification. The unflighted section determination unit 36 in FIG. 4 determines the flight path determined for any one drone 10 based on the position of each drone 10 acquired by the acquisition unit 31 and the flight route determined for each drone 10. When the drone 10 has finished flying, it is determined whether there is an unflighted section in the flight path determined for the other drone 10. Note that the unflighted section here refers to a section in which the drone 10 is supposed to make a notification regarding a disaster, but has not yet completed the notification regarding the disaster because it has not flown yet (the same applies below).

If the unflighted area determination unit 36 determines that there is an unflighted area, the flight availability determination unit 37 determines whether the drone 10 that has completed flying the flight route can fly the unflighted area. . Specifically, the flight permission determination unit 37 determines whether the drone 10 can fly the unflighted section based on the remaining power level of the drone 10 that has completed flying the flight route. In other words, the flight permission determination unit 37 determines that if the remaining power of the drone 10 that has completed flying the flight route is greater than or equal to the power required to fly the unflighted area, the drone 10 can fly the unflighted area. On the other hand, if the remaining power of the drone 10 that has completed flying the flight route is less than the power required to fly the unflighted section, it is determined that the drone 10 is not capable of flying the unflighted section. do. Note that, here, if the drone 10 that has completed flying the flight route can fly at least part of the unflighted section (a section corresponding to at least one or more meshes), then the drone 10 flies the unflighted section. Determined to be flightable.

In addition, if the drone 10 that has completed flying the flight route, the departure/arrival base equipped with charging equipment, and the unflighted area are close to each other, the drone 10 may be charged at the charging equipment and then be charged in the unflighted area. It is also possible to start a flight against. Therefore, when it is determined that there is an unflighted section, the flight availability determination unit 37 determines the current position and remaining power of the drone 10 that has completed the flight route, as well as the charging equipment that can charge the drone 10. Based on the position and the amount of power charged by the drone 10 at the charging facility, it is determined whether the drone 10 can fly in the unflighted section.

When it is determined that the drone 10 that has completed its flight as described above can fly in the unflighted area of another drone 10, the flight route determination unit 34 allows the drone 10 to fly at least part of the unflighted area of the other drone 10. Determine the flight path including. Then, the output unit 35 outputs the flight route determined by the flight route determination unit 34 as well as broadcast information indicating the content to be broadcast by the drone 10 to the drone 10 via the communication network 20. The drone 10 controls its flight along the output flight route based on its own position, altitude, and attitude, and also makes notifications regarding disasters according to notification information.

[motion]
Next, with reference to FIG. 13, an operation in which the server device 30 first determines a flight path for each drone 10 will be described. In FIG. 13, the acquisition unit 31 acquires disaster prevention information indicating the occurrence of an event that causes a disaster and the area affected by the disaster (step S11).

The mesh extraction unit 33 determines the size of the mesh (mesh size) according to the various conditions described above (step S12).

Then, the mesh extraction unit 33 extracts a plurality of meshes that cover the area targeted for notification regarding the disaster indicated by the disaster prevention information, according to the mesh size determined in step S12 (step S13).

Next, the flight route determination unit 34 determines a flight route that includes the order in which the drone 10, which provides notification regarding the disaster indicated by the disaster prevention information, flies over the plurality of extracted meshes (step S14).

The output unit 35 outputs the flight route determined by the flight route determining unit 34 as well as notification information for the drone 10 to report on the disaster indicated by the disaster prevention information to the drone 10 via the communication network 20 (step S15). According to this output, the drone 10 performs flight control along this flight path based on its own position, altitude, and attitude, and makes a notification from the notification device 10061 according to the above notification information.

Next, with reference to FIG. 14, an operation in which the server device 30 re-determines the flight path of the drone 10 that has completed flying the initially determined flight path will be described. In FIG. 14, the unflighted section determination unit 36 determines the flight path determined for any of the drones 10 based on the position of each drone 10 acquired by the acquisition unit 31 and the flight route determined for each drone 10. It is determined whether the drone 10 has finished flying (step S21).

If the unflighted section determination unit 36 determines that the drone 10 has finished flying the flight route determined for one of the drones 10 (step S21; YES), the unflighted section determination unit 36 determines that the unflighted section determination unit 36 has completed flying the flight route determined for the other drone 10 (step S21; YES). Determine whether there are any unflighted sections that have not been flown. (Step S22).

Then, if it is determined that there is an unflighted section in which the flight route determined for the other drone 10 has not been flown (step S22; YES), the flight permission determination unit 37 determines whether or not the drone has completed flying the flight route. 10 determines whether it is possible to fly the unflighted section (step S23).

Here, FIG. 15 is a diagram illustrating flight paths of a plurality of drones (here, the drones 10a and 10b), respectively. In FIG. 15, it is assumed that the drone 10a that started flying from the departure/arrival base B1 has completed flying the flight route R1 (solid line arrow in the figure) that passes through a total of 16 meshes from mesh m1 to mesh m2. At this time, the drone 10b that started its flight from the departure and arrival base B2 flies through a total of 5 meshes from mesh m3 to m4 out of a total of 16 meshes from mesh m3 to mesh m6. It is assumed that the aircraft has finished flying section R2 (dashed line arrow in the figure). In this case, of the flight route from mesh m3 to mesh m6, the flight section that passes through a total of 11 meshes from mesh m5 to mesh 6 corresponds to an unflighted section in which the drone 10b has not yet flown.

The flight availability determining unit 37 determines that the remaining power of the drone 10a after flying the flight route R1 is determined to be sufficient for a flight that passes through one or more of the flight sections from the mesh m2 to the mesh m6 and the unflighted sections. If the electric power is greater than or equal to the power required to fly the flight section and the flight section for returning to any departure/arrival base, it is determined that the drone 10a can fly the unflighted section. In the example of FIG. 15, the remaining power of the drone 10a after flying the flight route R1 is determined by the remaining power of the drone 10a in the flight section from mesh m2 to mesh m6, and in total from mesh m6 to m8 in the unflighted section. It is assumed that the electric power is greater than or equal to the power required to fly the flight route R3 (dotted chain arrow in the figure), which includes the entire flight section via the mesh m8 and the flight section from the position of the mesh m8 to the departure and arrival base B1.

However, the time when the drone 10a reaches any one or more meshes (each of the five meshes m6 to m8 in FIG. 15) in the unflighted section is longer than the time when the drone 10b reaches that mesh. It needs to be in front. For this reason, the flight availability judgment unit 37 makes the above judgment based on the current position, flight speed, and remaining power of the drones 10a and 10b, the position of each mesh included in the unflighted section, and the position of the departure and arrival base. conduct. By making decisions that take these things into consideration, a flight that does not waste time can be achieved, such as when the drone 10a reaches mesh m8, the drone 10b reaches the last remaining mesh m7 in the unflighted section. It can be a plan.

Furthermore, as described above, if the drone 10 that has completed its flight route, the departure/arrival base equipped with charging equipment, and the unflighted section are relatively close to each other, the drone 10 may be charged at the charging equipment. From there, it is also possible to start flying the unflighted section. Therefore, when it is determined that there is an unflighted section, the flight availability determination unit 37 determines the current position and remaining power of the drone 10 that has completed the flight route, as well as the charging equipment that can charge the drone 10. Based on the position and the amount of power charged by the drone 10 at the charging facility, it is determined whether the drone 10 can fly in the unflighted section. Furthermore, if there are multiple charging facilities and there are no reservations made during the desired time slot for charging and these charging facilities are vacant, the flight availability determination unit 37 determines that there is an unflighted section. In this case, the current position and remaining power of the drone 10 that has completed the flight route, the positions of multiple charging facilities that can charge the drone 10, and the amount of power that the drone 10 charges at each charging facility. Based on this, it is determined whether the drone 10 is able to fly in the unflighted section. Further, the flight availability determining unit 37 calculates the charging time for the drone 10 to charge the minimum amount of power necessary to fly the next unflighted section. The flight route determination unit 34 may be instructed to determine a flight route including the charging time.

In the example of FIG. 16, similarly to FIG. 15, when the drone 10a finishes flying the flight route R1 that passes through a total of 16 meshes from mesh m1 to mesh m2, the drone 10b flies from mesh m3 to mesh m6. It is assumed that the flight route R2, which passes through a total of 5 meshes from mesh m3 to m4, out of a flight route that passes through a total of 16 meshes, has been completed. As described above, the unflighted section at this time is a flight route that passes through a total of 11 meshes from mesh m5 to mesh 6.

In such a case, the flight permission determination unit 37 determines that the sum of the remaining power of the drone 10a after flying the flight route R1 and the amount of power obtained by charging with the charging equipment of the departure/arrival base B2 is the mesh m2. The electric power required to fly the flight section from to mesh m6, the flight section that passes through any one or more of the above-mentioned non-flying sections, and the flight section for returning to any departure/arrival base. For example, it is determined that the drone 10a can fly in the unflighted section. In the example of FIG. 15, the sum of the remaining power of the drone 10a after flying the flight route R1 and the amount of power obtained by charging with the charging equipment at the departure and arrival base B2 is the sum of the amount of power remaining for the drone 10a that has completed flying the flight route R1 and the amount of power obtained by charging with the charging equipment at the departure and arrival base B2. A flight section, a flight section from departure and arrival base B2 to mesh m6, a flight section that passes through a total of 5 meshes from mesh m6 to m8 among the unflighted sections, and from the position of mesh m8 to departure and arrival base B1. It is assumed that the power is greater than or equal to the power required to fly the flight route R4 (dotted chain arrow in the figure) including the flight section.

In addition, in the example of FIG. 16, similarly to FIG. 15, the timing when the drone 10a reaches any one or more meshes (in FIG. 15, each of the five meshes from mesh 6 to m8) in the unflighted section is determined by , before the time when the drone 10b reaches the mesh. For this reason, the flight availability determination unit 37 determines the current position, flight speed, and remaining power of the drones 10a and 10b, the position of each mesh included in the unflighted section, the position of the departure and arrival base, and the charging equipment of the departure and arrival base. The above judgment is made based on the charging speed and charging time when charging. By making decisions that take these things into consideration, for example, when the drone 10a reaches mesh m8, the drone 10b reaches the last remaining mesh 7 in the unflighted section. It can be a plan.

Returning to the explanation of FIG. 14, when it is determined that the drone 10 is able to fly in the unflighted area as described above (step S23; YES), the flight route determining unit 34 determines the unflighted area for the drone 10. A flight path including the flight path is determined (step S24). In other words, in the case of the example in FIG. 15, for the drone 10a that has completed the flight on the flight route R1, the flight section from mesh m2 to mesh m6, the flight section from mesh m6 to m8 among the unflighted sections, and the flight section from mesh m8 to mesh m8. A flight route R3 (dotted chain arrow) from the departure and arrival base B1 is determined. In the case of the example shown in FIG. 16, for the drone 10a that has completed the flight on the flight route R1, the flight section from the mesh m2 to the departure and arrival base B2, the flight section from the departure and arrival base B2 to the mesh m6, and the unflighted section are meshed. A flight section from m6 to m8 and a flight route R4 (dotted chain arrow) from mesh m8 to departure/arrival base B1 are determined.

When it is determined that the drone 10 can fly in the unflighted area as described above, the flight route determining unit 34 determines a flight path for the drone 10 that includes the unflighted area. Then, the output unit 35 outputs the flight route determined by the flight route determination unit 34 as well as notification information for the drone 10 to notify the disaster indicated by the disaster prevention information to the drone 10 via the communication network 20 (step S25 ). According to this output, the drone 10 performs flight control along this flight path based on its own position, altitude, and attitude, and makes a notification from the notification device 10061 according to the above notification information.

According to the embodiments described above, it becomes possible to appropriately determine the flight paths for each of the plurality of drones 10 to provide notification regarding a disaster.

[Modified example]
The invention is not limited to the embodiments described above. The embodiment described above may be modified as follows. Furthermore, two or more of the following modifications may be implemented in combination.

[Modification 1]
The mesh may have a different size depending on the type or scale of the disaster indicated by the disaster prevention information. For example, a large mesh is used for disasters that tend to occur over a wide area and instantaneously (e.g. earthquakes and tsunamis), a small mesh is used for disasters that tend to occur over a narrow area and for a certain amount of time (e.g. floods and fires), and other A possible example would be to use medium mesh in the case of a disaster.

[Modification 2]
The server device 30 may include a notification content determination unit that determines the content of notifications performed by the drone 10 in mesh units. For example, evacuation sites may vary depending on the scale and combination of events that cause a disaster. Therefore, the storage unit 32 may store the mesh ID of each mesh and the content to be notified in that mesh in association with each other.

[Modification 3]
For example, if the drone 10 flies over a mesh where weather conditions such as wind speed and rainfall exceed the permissible flight range for the drone 10, the risk of the drone 10 falling or malfunctioning increases. It is desirable to exclude them from the flight path. Therefore, the mesh extraction unit 33 excludes from the extraction targets meshes whose weather conditions are worse than a certain level, even if they are included in the area targeted for disaster notification indicated by the disaster prevention information. The weather conditions for each mesh may be acquired by the server device 30 from, for example, a website that publishes weather information (including forecasts) for each region on the Internet.

At this time, disaster-related notifications will not be made in the meshes excluded from the extraction targets. Therefore, the flight route determining unit 34 selects a case where a mesh adjacent to a mesh excluded based on weather conditions (adjacent mesh) is extracted from among the meshes included in the area targeted for disaster notification indicated by the disaster prevention information. When announcing a disaster in the neighboring mesh, there is a method that allows the announcement to be made over a wider area (for example, a method that outputs a message sound calling for evacuation from a speaker at a loud volume that can reach other areas). etc.) determines a flight route that includes notification information that instructs to make notifications.

As described above, the mesh extraction unit 33 excludes meshes whose weather conditions are worse than a certain level from the extraction targets even if they are included in the area targeted for disaster notification indicated by the disaster prevention information. Furthermore, if a mesh adjacent to a mesh excluded based on weather conditions (adjacent mesh) is extracted from among the meshes included in the area targeted for disaster notification indicated by the disaster prevention information, the flight route determination unit 34 may determine a flight route that includes notification information that instructs to make notifications in a manner that allows notification to be made over a wider area when making notifications regarding disasters in the adjacent mesh. In this way, it is possible to provide notification regarding a disaster while ensuring the safety of the drone 10 under bad weather.

[Modification 4]
The flight path determination unit 34 sequentially performs simulations under all conditions for flight paths passing through meshes included in a plurality of unflighted sections, and determines a flight path that allows the flight to be completed in the shortest time. Good too. All of the conditions here include, for example, unexpected consumption of the remaining power of the drone 10 due to wind speed or aircraft deterioration, a malfunction of the drone 10, an unexpected fall of the drone 10 due to the malfunction, and an unexpected drop of the drone 10 due to wind speed or amount of rain. This includes thinning flights due to the occurrence of meshes that cannot be flown. In this way, when it is determined that the drone 10 is capable of flying over a plurality of unflighted sections, the flight path determination unit 34 determines a flight path that allows the drone 10 to fly over the plurality of unflighted sections in the shortest period of time. You may also do so. In this way, notification regarding the disaster can be completed in the shortest possible time.

[Modification 5]
Each mesh may have many residents who speak languages other than Japanese. Therefore, it is possible to decide the language in which disaster announcements are made based on the stay data of foreigners identified using statistical methods of population trends, such as NTT Docomo's Mobile Spatial Statistics (registered trademark). good. Using such a statistical method, one or more languages in which announcements are made in each mesh are determined in advance, and the flight path determination unit 34 determines a flight path that includes notification information in the language used in each mesh. In this way, notifications can be made in accordance with the language used by the people in each mesh.

[Modification 6]
For example, when a tsunami occurs, the closer you are to the coastline, the faster the tsunami will arrive, so in hazard maps created by local governments, tsunami areas are set starting from the coastline, and larger tsunamis occur inland. Areas may be set. Early notification of disasters at coastal areas where tsunamis arrive quickly is considered effective from the perspective of saving lives. Therefore, the flight route determination unit 34 refers to the hazard map and determines the flight route by giving top priority to the tsunami warning area, then giving priority to the tsunami warning area, and then giving priority to the major tsunami warning area. You can do it like this. Note that the priority determined for each mesh is not limited to the above example, and for example, the higher the population density, the higher the priority may be. In this way, effective disaster notification can be realized when a tsunami occurs.

[Modification 7]
The block diagram used to describe the above embodiments shows blocks in functional units. These functional blocks (components) are realized by any combination of hardware and/or software. Further, the means for realizing each functional block is not particularly limited. That is, each functional block may be realized by one physically and/or logically coupled device, or may be realized by directly and/or indirectly implementing two or more physically and/or logically separated devices. It may also be realized by a plurality of devices connected to each other (for example, by wire and/or wirelessly). In short, each of the functions illustrated in FIG. 4 may be provided in any of the devices constituting the disaster prevention information notification system 1.
