<Embodiment 1>
FIG. 1 is a block diagram showing the overall configuration of the information processing device 1 according to the first embodiment. The information processing device 1 receives emergency information for notifying a disaster or the like via the communication satellite 2, outputs information regarding the emergency information via the output device 3, and notifies the wireless communication terminal 4 of the emergency information. To do. The information processing device 1 includes a first wireless communication unit 11, an output control unit 12, and a second wireless communication unit 13.

  The first wireless communication unit 11 receives a first wireless signal including emergency information from the communication satellite 2. Here, the emergency information includes disaster information related to natural disasters such as earthquakes, tsunamis, typhoons, and crisis management information such as terrorism and missile launches. Then, the emergency information is transmitted as a radio signal to the communication satellite 2 by a predetermined control station from a public organization such as the government, and can be received by the first wireless communication unit 11 via the communication satellite 2. Shall be.

  The output control unit 12 outputs via the output device 3 based on the emergency information included in the first wireless signal. Here, the output device 3 includes, for example, a display device having a screen, a speaker that outputs sound, and the like. Therefore, the output control unit 12 outputs the alarm information and the like based on the emergency information via the output device 3.

  The second wireless communication unit 13 includes the emergency information in the second wireless signal and transmits it to the wireless communication terminal 4 within the predetermined range. The second wireless communication unit 13 may be any unit that transmits the second wireless signal to at least one or more wireless communication terminals 4. Here, it is assumed that the second wireless signal is a signal based on a wireless communication standard different from that of the first wireless signal. That is, the first wireless communication unit 11 performs wireless communication with the communication satellite 2 based on the first wireless communication standard, and the second wireless communication unit 13 performs second wireless communication with the wireless communication terminal 4. It can be said that wireless communication is performed based on the wireless communication standard.

  FIG. 2 is a flowchart showing the flow of the emergency information notification method according to the first embodiment. First, the first wireless communication unit 11 receives a first wireless signal including emergency information from the communication satellite 2 (S11). Next, the output control unit 12 outputs via the output device 3 based on the emergency information included in the first wireless signal (S12). Further, the second wireless communication unit 13 includes the emergency information in the second wireless signal and transmits it to the wireless communication terminals 4 within the predetermined range (S13). Note that steps S12 and S13 do not have to be parallel processing, and one may be processed before the other.

  As described above, the information processing device 1 according to the first embodiment notifies the information about the emergency information received from the communication satellite 2 to the surrounding people through the output device 3 and the wireless communication terminal 4 existing in the predetermined range. Also, the emergency information is transmitted by the second wireless signal. Therefore, a person who possesses the wireless communication terminal 4 appropriately recognizes emergency information even when the wireless communication terminal 4 cannot directly receive a signal from the communication satellite 2 (has no function of directly receiving the signal). be able to. Therefore, according to the first embodiment, it is possible to more appropriately transmit the emergency alert to the people at the disaster site.

  The information processing device 1 includes a processor, a memory, and a storage device, which are not shown. Further, the storage device stores a computer program in which the processing of the emergency information notification method according to the first embodiment is implemented. Then, the processor reads the computer program from the storage device into the memory and executes the computer program. Thereby, the processor operates as the first wireless communication unit 11, the output control unit 12, and the second wireless communication unit 13.

  Alternatively, each of the first wireless communication unit 11, the output control unit 12, and the second wireless communication unit 13 may be realized by dedicated hardware.

<Embodiment 2>
The second embodiment is a specific example of the above-described first embodiment. Here, as an example of the above-mentioned emergency information, in Japan, there is disaster information that combines information on natural disasters (earthquakes, tsunamis, typhoons, etc.) and information on national protection (ballistic missile attacks, etc.). As the current disaster prevention information network, there is a mechanism for notifying disaster information from national organizations such as national alert system (J alert). The disaster prevention information network has a multi-stage system in which disaster information from ministries and agencies is routed through multiple routes via the Fire Department, mobile phone companies, local public bodies, and the like. Therefore, a delay may occur before the disaster information is transmitted to a person who should recognize the disaster information. Moreover, since the transmission route differs depending on the ministry or agency from which the disaster information is transmitted, the reception destination is also various such as fire stations, outdoor speakers, televisions, radios, mobile phones, and smartphones. Therefore, the disaster information may not be transmitted to humans depending on the agency or the type of information.

  Therefore, in recent years, utilization of a submeter-class positioning reinforcement signal (L1S signal) that can be relayed by the quasi-zenith satellite "Michibiki" has been studied. For example, it is possible to unify disaster information from specific ministries and agencies by consolidating disaster information from a specific control station and transmitting the radio waves to the quasi-zenith satellite including the disaster information in the L1S signal. Be done. A dedicated Global Navigation Satellite System (GNSS) antenna that can receive L1S signals is also becoming widespread. Here, GNSS is also called a global positioning satellite system, and for example, satellite positioning such as GPS (Global Positioning System), GLONASS (GLObal NAvigation Satellite System), Galileo, and quasi-zenith satellite system (QZSS). It includes a system. However, the dedicated GNSS antenna is expensive at present, and it is said that it is difficult to implement the GNSS antenna in a general mobile phone terminal, a wireless communication terminal such as a smart phone, from the viewpoint of cost. Further, since the L1S signal is transmitted at 4-second intervals, it is desirable for the receiving side to check reception at 4-second intervals. Currently, from the viewpoint of battery consumption restrictions, etc., it should be installed in a general wireless communication terminal. However, it is still considered difficult.

  Therefore, if an emergency vehicle (fire engine, ambulance, police car, etc.) equipped with the GNSS antenna and the information processing device 1 according to the first embodiment rushes to the site of a disaster, the surrounding people and surrounding It can be said that the wireless communication terminal can be notified of disaster information. Therefore, the emergency information notification system according to the second embodiment will be described below as an example of realizing these.

  FIG. 3 is a block diagram showing the configuration of the emergency information notification system 1000 according to the second embodiment. In the emergency information notification system 1000, the communication satellite 22 relays the first wireless signal transmitted from the control station 21, and the information processing device 110 mounted on the emergency vehicle 10 receives the first wireless signal. Then, the information processing device 110 outputs information based on the emergency information via the output device 120, and delivers the second wireless signal including the emergency information to the wireless communication terminals 31 and 32 within the predetermined range. .. Further, the wireless communication terminal 31 distributes a second wireless signal from itself to the wireless communication terminals 33 and 34 in a predetermined range, and the wireless communication terminal 33 transmits a second wireless signal from itself to the wireless communication terminals 35 in a predetermined range. To deliver. The emergency information notification system 1000 according to the second embodiment refers to at least one of the above information processing devices. When the emergency information notification system 1000 includes two or more information processing devices, each information processing device has an equivalent configuration, each receives the first wireless signal, and the output device and the wireless communication terminal within the predetermined range. Emergency information should be output to.

  The control station 21 receives emergency information from an information system (not shown) such as a ministry, and transmits a first wireless signal including the emergency information to the communication satellite 22. Here, the emergency information may be the above-mentioned disaster information, and includes, for example, information on disaster prevention and weather from each ministry and the Meteorological Agency, armed attack information from the Cabinet Secretariat, and the like. Therefore, in the case of an earthquake, the emergency information includes the date and time of occurrence, the area name (text information) indicating the epicenter, the position information (latitude, longitude, etc.), the depth of the earthquake, the magnitude of the earthquake, and the like. The emergency information also includes weather information such as typhoons and floods, and information such as fires.

  Further, the first wireless signal may be a part of the reinforcement signal for reinforcing the positioning. For example, when the communication satellite 22 is a quasi-zenith satellite, emergency information may be included in the reinforcement signal. In that case, you may use the above-mentioned L1S signal as a reinforcement signal.

  Each of the wireless communication terminals 31 to 35 is a mobile phone terminal, a smartphone, a tablet terminal, or any other information processing terminal capable of wireless communication. Therefore, as the wireless communication terminal 31 and the like, known terminals can be used.

Here, as the specific communication protocol, for example, DTN (Delay, Disruption, Disconnection Tolerant Networking) or the like can be used, but the specific communication protocol is not limited thereto. In FIG. 3, it is assumed that the emergency vehicle 10 and the wireless communication terminal 31, and the emergency vehicle 10 and the wireless communication terminal 32 are located at a distance where wireless communication is possible based on a specific communication protocol. However, it does not matter whether or not the wireless communication terminals 31 and 32 are present at a distance where wireless communication by a specific communication protocol is possible. Further, it is assumed that the wireless communication terminal 31 and the wireless communication terminal 33, and the wireless communication terminal 31 and the wireless communication terminal 34 are present at a distance where wireless communication is possible based on a specific communication protocol. Further, the wireless communication terminal 33 and the wireless communication terminal 35 are assumed to exist at a distance where wireless communication is possible based on a specific communication protocol. That is, the emergency vehicle 10 cannot directly communicate with the wireless communication terminals 33, 34 and 35.

The emergency vehicle 10 has a wireless antenna (not shown) for performing wireless communication based on the above-described specific communication protocol. For example, the wireless antenna may be built in the information processing device 110. Further, the wireless antenna may include processing by firmware that converts an analog signal and a digital signal.

  FIG. 5 is a block diagram showing the internal configuration of the information processing apparatus 110 according to the second embodiment.

The information processing device 110 includes a storage unit 41, a wireless communication IF (InterFace) 42, a wireless communication IF 43, a communication IF 44, and a control unit 45. The storage unit 41 is a volatile or non-volatile storage device. The storage unit 41 stores the emergency information 411, the content list 412, and the program 413. The emergency information 411 corresponds to the information included in the first wireless signal described above, and is, for example, text data. Then, in this embodiment, the emergency information 411 is regarded as the content. The content list 412 is information listing the indexes of the emergency information 411. The content list 412 is, for example, a list of identification information and update date and time of each content (emergency information 411). The program 413 is a computer program that implements the processing of the emergency information notification method according to the second embodiment.

  The wireless communication IF 42 is an interface circuit for exchanging data with the GNSS antenna 130. For example, the built-in decoding software converts a digital signal output from the GNSS antenna 130 into text data and outputs the text data to the control unit 45. To do. The wireless communication IF 43 is an interface circuit that exchanges data with a wireless antenna for performing wireless communication based on the specific communication protocol described above. The wireless communication IF 43 converts, for example, text data output from the information processing device 110 into a second wireless signal based on a specific communication protocol and outputs the second wireless signal to the wireless antenna. Then, the wireless antenna converts the digital signal into an analog signal and transmits the analog signal. The communication IF 44 is an interface circuit that exchanges data with the display device 121 and the speaker 122. The communication IF 44 performs predetermined conversion on image data, audio data, etc. output from the information processing device 110, and outputs the image data and audio data to the display device 121 and the speaker 122, respectively.

  The control unit 45 is a control circuit including a processor such as a CPU (Central Processing Unit) and a memory. The control unit 45 reads the program 413 from the storage unit 41 into the memory and causes the processor to execute the program 413. As a result, the control unit 45 operates as the first wireless communication unit 451, the output control unit 452, and the second wireless communication unit 453.

  The first wireless communication unit 451 is a software module that is an example of the above-described first wireless communication unit 11, receives a signal related to the first wireless signal from the wireless communication IF 42, and outputs emergency information from the first wireless signal. Extract. Then, the first wireless communication unit 451 stores the extracted emergency information in the storage unit 41 as the emergency information 411 and, at the same time, adds the index information of the emergency information 411 to the content list 412. Alternatively, the first wireless communication unit 451 may store the emergency information 411 and the content list 412 in the memory. In addition, the first wireless communication unit 451 updates the content list 412 each time the emergency information is received.

  The output control unit 452 is a software module that is an example of the output control unit 12 described above, and generates output information that is image data or audio data to be output from the output device 120 based on the emergency information 411. Here, the first wireless signal is assumed to include position information regarding emergency information. For example, the first wireless signal includes the latitude and longitude information of the position information of the area where the disaster indicated by the emergency information occurs. Further, the storage unit 41 may store map information including the area in advance. In this case, the output control unit 452 refers to the map information in the storage unit 41, generates image data including an area corresponding to the position information regarding the emergency information, and outputs the image data so that the display device 121 displays the image data. ..

  The second wireless communication unit 453 is a software module that is an example of the second wireless communication unit 13 described above. The second wireless communication unit 453 generates a second wireless signal including the content list 412. Also, the second wireless communication unit 453 generates a second wireless signal by using the emergency information 411 as the content to be data-synchronized. Then, the second wireless communication unit 453 transmits the second wireless signal in response to data synchronization (contents synchronization processing) with the wireless communication terminal 31 or the like. The second wireless communication unit 453 may use, for example, WiFi (registered trademark) multicast, DTN, broadcast, or the like as information transmission based on a vehicle dynamics management system (AVM (Automatic Vehicle Monitoring System)). Therefore, when there are a plurality of wireless communication terminals capable of wireless communication with the same communication protocol as the second wireless communication unit 453 within a predetermined range, the second wireless communication unit 453 collectively collects the second wireless communication terminals for all the wireless communication terminals. Radio signals can be delivered.

You may make it perform the process corresponding to a standard.

  FIG. 6 is a flowchart showing the flow of processing of the information processing apparatus 110 according to the second embodiment. First, the first wireless communication unit 451 of the information processing device 110 receives a first wireless signal including emergency information from the communication satellite 22 (S21). At this time, the first wireless communication unit 451 extracts the emergency information from the first wireless signal.

  Next, the output control unit 452 of the information processing device 110 generates output information based on the emergency information (S22). For example, the output control unit 452 generates the image data of the map information corresponding to the position information included in the emergency information as the output information as described above. Further, the output control unit 452 generates an alarm sound as output information such as the level of emergency information. Alternatively, the output control unit 452 generates a warning message from the text information indicated by the emergency information, converts the warning message into voice data, and generates it as output information.

  Then, the output control unit 452 controls the output device 120 so that the output information is output (S23). For example, the output control unit 452 outputs the generated image data to the display device 121 to display it. Further, the output control unit 452 outputs the generated alarm sound and voice data to the speaker 122 and outputs them as sound.

  Further, independently of steps S22 and S23, the second wireless communication unit 453 of the information processing device 110 performs content synchronization processing with the wireless communication terminals 31 and 32 within a predetermined range (S24).

  FIG. 7 is a flowchart showing the flow of the content synchronization processing according to the second embodiment. First, the second wireless communication unit 453 establishes a wireless connection within a predetermined range (S31). That is, the second wireless communication unit 453 establishes a wireless connection with each of the wireless communication terminals 31 and 32 existing within a predetermined range by a specific wireless communication protocol. Next, the second wireless communication unit 453 exchanges the content list 412 with each wireless communication terminal 31 or the like wirelessly connected (S32). For example, the second wireless communication unit 453 reads the content list 412 from the storage unit 41, generates a second wireless signal including the content list 412, and outputs the second wireless signal to the wireless communication IF 43. Then, the wireless communication IF 43 transmits the second wireless signal via a wireless antenna based on a specific wireless communication protocol. Further, the second wireless communication unit 453 receives the content list regarding the emergency information from each of the wireless communication terminals 31 and 32 within the predetermined range, and holds the received content list in the storage unit 41 or the memory.

  Then, the second wireless communication unit 453 compares the content list received from the wireless communication terminal 31 or the like with the content list 412 stored in the storage unit 41 (S33). .. For example, the second wireless communication unit 453 compares the update date and time and the identification information of the emergency information associated with the index of each content in the comparison target content list.

  Then, the second wireless communication unit 453 determines whether or not there is insufficient content in its own content list 412 (S34). That is, the second wireless communication unit 453 determines whether or not there is content included in the received content list but not included in the content list 412.

  If it is determined in step S34 that there is insufficient content, the second wireless communication unit 453 requests the wireless communication terminal of the connection destination that has provided the corresponding content list to provide the insufficient content (S35). The missing content is acquired from the connection destination (S36). Then, the second wireless communication unit 453 stores the acquired content as the emergency information 411 in the storage unit 41, and adds the identification information of the acquired content and the like to the content list 412.

  In addition, the second wireless communication unit 453 determines whether or not a content request has been received from the wireless communication terminal of the connection destination (S37). When the content request is received, the second wireless communication unit 453 reads the emergency information 411 corresponding to the content request from the storage unit 41, and sets the emergency information 411 as the content to the wireless communication terminal of the connection source that is the request source. The included second wireless signal is transmitted (S38). The processing order of steps S34 to S36 and steps S37 and S38 is not limited to this.

  Further, each of the data synchronization applications 310 to 350 installed in the wireless communication terminals 31 to 35 also performs the content synchronization processing shown in FIG. 7.

  Subsequently, a case where the emergency information transmitted from the control station 21 propagates to the wireless communication terminal 35 and the like will be described with reference to the sequence diagram of FIG. First, the control station 21 generates a first wireless signal including emergency information to be notified and transmits it to the communication satellite 22 (S201). In response to this, the communication satellite 22 receives the first wireless signal from the control station 21, and transmits, that is, relays the first wireless signal toward the ground such as the emergency vehicle 10. Then, the first wireless communication unit 451 of the information processing device 110 receives the first wireless signal from the communication satellite 22 via the GNSS antenna 130, and extracts the emergency information from the first wireless signal.

  Subsequently, the output control unit 452 of the information processing device 110 generates the above-mentioned output information from the extracted emergency information (S202). Then, the output control unit 452 controls the output device 120 to output the output information (S203). In response to this, the output device 120 outputs the output information (S204).

  The second wireless communication unit 453 of the information processing device 110 establishes wireless connection with the wireless communication terminals 31 and 32 within the predetermined range (S205). Then, as described above, the second wireless communication unit 453 exchanges the content list with each of the wireless communication terminals 31 and 32 that are wirelessly connected (S206). Here, new emergency information is registered in the content list 412 held by the information processing apparatus 110. Therefore, each of the wireless communication terminals 31 and 32 makes a content request to the information processing apparatus 110 based on a specific communication protocol. Then, the second wireless communication unit 453 transmits a second wireless signal including emergency information to each of the wireless communication terminals 31 and 32 in response to the content request (S207). In response to this, the data synchronization application 310 of the wireless communication terminal 31 outputs according to the emergency information included in the received second wireless signal (S208-1). Similarly, the data synchronization application 320 of the wireless communication terminal 32 also outputs according to the emergency information included in the received second wireless signal (S208-2).

  Subsequently, the data synchronization application 310 establishes a wireless connection with the wireless communication terminal 33 or the like within a predetermined range (S209-1), and exchanges the content list with the wireless communication terminal 33 or the like wirelessly connected ( S209-2). Although only the wireless communication terminal 33 is shown as a representative in FIG. 8, the same applies to the wireless communication terminal 34. Here, since the new emergency information is registered in the content list held by the wireless communication terminal 31, the data synchronization application 330 or the like of the wireless communication terminal 33 or the like is based on a specific communication protocol with respect to the data synchronization application 310. Make a content request. Then, the data synchronization application 310 transmits a second wireless signal including emergency information to the wireless communication terminal 33 or the like in response to the content request (S209-3). In response to this, the data synchronization application 330 or the like of the wireless communication terminal 33 or the like outputs according to the emergency information included in the received second wireless signal (S210). After that, the same processing as in steps S209-1 to S209-3 and S210 is performed between the wireless communication terminal 33 and the wireless communication terminal 35.

  As described above, by the emergency information notification system 1000 according to the second embodiment, for example, the emergency vehicle 10 that has rushed to the disaster site receives the L1S signal via the communication satellite 22 to immediately notify the surrounding people of the emergency information. Can be notified. In addition, the information processing device 110 mounted on the emergency vehicle 10 can propagate the emergency information to the wireless communication terminal 31 and the like existing nearby based on a specific communication protocol. Therefore, even if a person who possesses the wireless communication terminals 31 and 32 that does not have the function of receiving the L1S signal cannot sufficiently recognize the emergency information from the output from the output device 120, he / she can quickly recognize the emergency information from his / her wireless communication terminal 31 or the like. Can recognize emergency information. Further, since the wireless communication terminals 33 to 35 existing outside the range of communication with the emergency vehicle 10 according to the specific communication protocol can also receive the emergency information propagated from the wireless communication terminal 31, the person who possesses them can promptly receive the emergency information. Emergency information can be transmitted. Therefore, even a person who is at a disaster site and cannot reach the emergency vehicle 10 or the like immediately can obtain the latest emergency information one after another and can take appropriate measures.

  Further, when the emergency information includes position information indicating the site of a disaster or the like, the information processing apparatus 110, the data synchronization application 310, or the like can display corresponding map information from the position information on a screen or the like. Therefore, it is possible to grasp a more dangerous place near the disaster site and avoid secondary damage.

  Further, for example, when communication based on DTN is used for the above-described data synchronization processing, the data synchronization applications 310 to 350 and the second wireless communication unit 453 are assumed to have the function of the DTN application. In that case, it is assumed that a dedicated ID has been issued to each DTN application. Then, the information processing apparatus 110 is assumed to hold the ID of the data synchronization application 310 or the like in advance. As a result, the information processing apparatus 110 can perform the content synchronization process only with the DTN application for which the ID included in the ID list held by itself has been set. Therefore, efficient communication becomes possible.

  For example, the fire brigade in each region may not be able to own the information processing device 110 or the like in terms of cost or the like. Even in that case, each fire brigade can install the data synchronization application 310 or equivalent on a general wireless communication terminal to share emergency information closely with the fire engine from the fire department at low cost. You can

  Further, by using the data synchronization processing, it is possible to quickly propagate the emergency information. For example, the information processing apparatus 110 keeps trying to establish a wireless connection based on a specific communication protocol, and automatically receives emergency information when approaching the emergency vehicle 10 while holding the wireless communication terminal equipped with the data synchronization application. can do. Further, by using DTN or the like, a standard mechanism can be adopted for security and the like, so that reliability and safety can be secured at low cost.

  Also, in the event of a disaster, the radio base station of the carrier line may be cut off due to a power outage or collapse. Even in such a case, by using DTN or the like for the data synchronization process, the wireless communication terminal can receive the emergency information at a minimum.

  Further, by adopting "Michibiki" as the communication satellite 22, the present embodiment can be realized at a low cost as compared with other GNSS communication satellites.

  In addition, since the information processing device 110 can be realized by a semiconductor integrated circuit, it can be mounted on various types of devices at low cost due to its miniaturization, and its spread can be promoted.

<Embodiment 3>
The third embodiment is an improved example of the second embodiment described above. The information processing apparatus according to the third embodiment further includes a first acquisition unit that acquires first media data indicating a situation of a region corresponding to the emergency information. Then, the output control unit further outputs the first media data via the output device, and the second wireless communication unit outputs the first media data or the first media data to the first media data. The access information of No. 1 is further included in the second wireless signal and transmitted. Thereby, for example, media data such as an image, a video, or a sound of a disaster site can be quickly output together with emergency information, and a person on the site can grasp the situation more accurately. Similarly, it is possible to more realistically convey the situation at the disaster site to people who have wireless communication terminals in locations where the disaster site cannot be directly seen, avoiding danger, and speeding up rescue operations more quickly. It can be carried out.

  Further, the information processing device may further include a registration unit that registers the first media data in a server corresponding to the first access information via a predetermined communication network. In that case, the second wireless communication unit further includes the first access information in the second wireless signal and transmits the first access information after the registration. As a result, the wireless communication terminal downloads the media data acquired from the server using the first access information, so that the person carrying the wireless communication terminal can quickly and quickly check the situation at the disaster site while suppressing the communication cost. You can figure it out.

  In addition, the information processing device may further include an instruction unit that instructs the media information collecting device existing in an area corresponding to the emergency information to collect the first media data according to the emergency information. In that case, the first acquisition unit acquires the first media data collected by the media information collection device. With this, when the detailed situation of the disaster site cannot be grasped from the location where the information processing device exists, by using the media information collecting device which exists near the site or can be headed to the site by remote control, More accurate media data can be acquired. Further, more accurate media data can be shared with surrounding wireless communication terminals.

  Further, when the information processing device receives the second access information for the second media data indicating the situation of the area corresponding to the emergency information, the information processing device performs the second access information based on the access based on the second access information. It is desirable to further include a second acquisition unit that acquires the media data. In this case, the output control unit further outputs the second media data via the output device. The second access information and the second media data may be the above-mentioned first access information and the first media data. Thereby, the media data acquired by the other information processing device can be quickly acquired and recognized. For example, after the first emergency vehicle arrives at the scene, acquires the media data, and registers it in the server, the second and subsequent emergency vehicles rushing to the scene can acquire the access information. In that case, the situation of the site can be grasped more accurately even in the case of the second and subsequent emergency vehicles, so that rescue personnel can plan a rescue operation without waiting for the arrival. Therefore, rescue activities can be started smoothly after arrival. For example, emergency fire brigade teams nationwide require a considerable amount of time when rushing to rescue assistance from areas other than the disaster area. Therefore, by mounting the information processing apparatus according to the present embodiment on the emergency vehicle of each emergency fire support team, it is possible to continuously update the emergency information and the media data on the spot while moving, which is more effective.

  Furthermore, it is preferable that the second wireless communication unit further includes the acquired second media data or the second access information in the second wireless signal and transmits the second wireless signal. As a result, the wireless communication terminals existing near the second and subsequent emergency vehicles that have arrived at the scene can quickly grasp the situation at the scene.

  Further, the emergency information notification method and the emergency information notification system according to this embodiment can be grasped as follows. That is, the first information processing apparatus acquires the media data indicating the situation of the area corresponding to the emergency information, and registers the media data in the server corresponding to the access information via the predetermined communication network. When the second information processing device receives the first wireless signal from the communication satellite and receives the access information, the second information processing device acquires the media data by accessing based on the access information. After that, the second information processing device outputs the media data via the second output device based on the emergency information included in the first wireless signal, and either the media data or the access information is output. On the other hand, the emergency information is included in the third wireless signal and transmitted to the second wireless communication terminal within the predetermined range. As a result, the same effect as described above is achieved.

  FIG. 9 is a block diagram showing the configuration of the emergency information notification system 2000 according to the third embodiment. The emergency information notification system 2000 is an improvement of the emergency information notification system 1000. In the emergency information notification system 2000, the control station 21a is connected to the communication network N. Further, each of the two emergency vehicles 10a and 10b can receive emergency information from the communication satellite 22, and is connected to the communication network N by wireless communication. Further, the emergency vehicle 10a and the wireless communication terminal 31 are present at a distance that enables wireless communication based on a specific communication protocol, and the emergency vehicle 10b and the wireless communication terminal 36 can perform wireless communication based on a specific communication protocol. Shall be present at a certain distance. The wireless communication terminal 36 and the data synchronization application 360 have the same functions as the wireless communication terminal 31 and the data synchronization application 310. Further, it is assumed that the mobile photographing device 23 is present at a distance where it can wirelessly communicate with the emergency vehicle 10a. The server 24 is also connected to the communication network N. Therefore, the control station 21a, the server 24, and the emergency vehicles 10a and 10b are communicably connected.

  The communication network N is a communication network such as the Internet, and includes a mobile telephone network or the like with a carrier line.

  The server 24 is a computer system that provides a general network storage service. Therefore, the server 24 has a storage device 240. The storage device 240 stores the media data 241 requested to be registered by the emergency vehicle 10a. The server 24 also notifies the control station 21a of access information (for example, URL (Uniform Resource Locator)) on the communication network N to the media data 241 on the storage device 240. Alternatively, the control station 21a may periodically access the server 24 via the communication network N to acquire the access information of the media data 241.

  In addition to the function of the control station 21 of FIG. 3, the control station 21a acquires access information to the media data 241 from the server 24 via the communication network N, and accesses the emergency vehicle 10a or 10b via the communication network N. Notify information.

  The mobile photographing device 23 is an example of a media information collecting device, and is, for example, a wirelessly controllable aerial photographing device such as a drone. The mobile image capturing device 23 captures an image showing a situation of a region corresponding to the emergency information at least in response to an instruction from the information processing device 110a of the emergency vehicle 10a, and transmits the captured image to the information processing device 110a. .. When the mobile image capturing device 23 is equipped with a microphone, the mobile image capturing device 23 also transmits sound data collected by the microphone to the information processing device 110a. Further, as the media information collecting device, instead of the mobile photographing device 23, a fixed photographing device or a sound collecting device may be used. Alternatively, as the media information collecting device, instead of the mobile photographing device 23, a photographing device or a sound collecting device mounted on the emergency vehicle 10a may be used.

  The emergency vehicle 10a includes an information processing device 110a, an output device 120a, and a GNSS antenna 130a. Similarly, the emergency vehicle 10b includes an information processing device 110b, an output device 120b, and a GNSS antenna 130b. The emergency vehicles 10a and 10b are assumed to have the same function. The information processing device 110a is an example of a first information processing device, and the information processing device 110b is an example of a second information processing device. Here, it is assumed that the emergency vehicle 10a first arrives near the area corresponding to the emergency information, and the emergency vehicle 10b exists in an area distant from the area or is heading for the area. The output devices 120a and 120b are the same as the output device 120 described above, and the GNSS antennas 130a and 130b are the same as the GNSS antenna 130 described above.

  FIG. 10 is a block diagram showing the internal configuration of the information processing device 110a according to the third embodiment. The information processing device 110a is an improvement of the above-described information processing device 110. Below, it demonstrates centering around difference with FIG. In the storage unit 41, in addition to the emergency information 411 and the content list 412, the program 413 is replaced with the program 413a, and the media data 414 and the access information 415 are added. The program 413a is a computer program implemented by adding the processing of the emergency information notification method according to the third embodiment to the above-described program 413. The media data 414 is either or both of image data captured by the mobile imaging device 23 and sound data collected. The access information 415 is information for accessing the media data 241 via the communication network N, and is, for example, a URL or the like. The content list 412 may include the identification information of the media data 414 or the access information 415.

  The control unit 45 reads the program 413a from the storage unit 41 into the memory and causes the processor to execute the program 413a. Accordingly, the control unit 45 operates as the instruction unit 454, the acquisition unit 455, and the registration unit 456 in addition to the first wireless communication unit 451, the output control unit 452, and the second wireless communication unit 453.

  In response to the acquisition of the emergency information 411, the instruction unit 454 instructs the mobile photographing device 23 existing in the area corresponding to the emergency information 411 to collect the media data. The acquisition unit 455 is an example of the above-described first acquisition unit, acquires the media data collected by the mobile imaging device 23, and stores the media data in the storage unit 41 as the media data 414. The registration unit 456 registers the media data 414 in the server 24 via the communication network N. At this time, the registration unit 456 acquires the access information 415 indicating the access destination of the media data 414 from the server 24. Alternatively, the information processing apparatus 110a may previously hold access information 415 indicating an access destination via the communication network N as a storage destination of the storage device 240 that is a registration destination of the media data 414. In this case, the registration unit 456 may register the media data 414 in the access information 415.

  The acquisition unit 455 is also an example of the second acquisition unit described above, and when the second access information is received from the outside, acquires the second media data by the access based on the second access information. . For example, the information processing device 110b can receive the access information 415 of the media data 414 registered by the information processing device 110a from the control station 21a. In that case, the acquisition unit 455 acquires the media data 414 from the server 24 via the communication network N based on the received access information 415.

  FIG. 11 is a flowchart showing the flow of processing of the information processing apparatus 110a according to the third embodiment. First, steps S21 to S23 are the same as those in FIG. 6 described above. Then, here, independently of step S22, the instruction unit 454 of the information processing apparatus 110a instructs the mobile photographing apparatus 23 to collect media data in response to the reception of the emergency information (S41). Next, the acquisition unit 455 of the emergency vehicle 10a acquires the media data collected from the mobile photographing device 23 (S42). Then, the output control unit 452 of the information processing device 110a controls the output device to output the obtained media data (S43). For example, when the media data is a captured image, the output control unit 452 outputs the captured image to the display device 121 and displays it.

  Further, independently of step S43, the registration unit 456 of the information processing device 110a registers the media data in the server 24 via the communication network N (S44). For example, the registration unit 456 connects to the communication network N using the wireless communication IF 43, and transmits a media data registration request with the server 24 as the destination. Then, the registration unit 456 acquires access information to the media data 241 from the server 24 via the communication network N (S45).

  After that, the second wireless communication unit 453 performs the content synchronization process with the emergency information 411 and the access information 415 as the content to be synchronized (S46). The content synchronization processing is the same as that of FIG. 7 described above except that the content is a set of the emergency information 411 and the access information 415, and thus detailed description thereof will be omitted. The second wireless communication unit 453 may use the synchronization target content as the media data 414 instead of or together with the access information 415. Further, when the synchronization target content is the media data 414, it is not always necessary to perform steps S44 and S45.

  Then, the process returns to step S42, and steps S42 to S46 are repeated each time the media data is acquired from the mobile photographing device 23. Alternatively, steps S43 to S46 may be executed at a timing when the media data has become a certain unit.

  FIG. 12 is a flowchart showing the flow of processing of the information processing apparatus 110b according to the third embodiment. First, the information processing apparatus 110b performs the same processes as in FIG. 11 for steps S21 to S23, and a description thereof will be omitted. Then, independently of step S22, the acquisition unit 455 of the information processing device 110b receives the access information via the communication network N (S40). For example, the acquisition unit 455 may receive access information from the control station 21a via the communication network N by the wireless communication IF 43 or the like.

  Next, the acquisition unit 455 acquires the media data 241 from the server 24 via the communication network N based on the received access information (S42a) and stores it in the storage unit 41 or the memory. Then, the output control unit 452 of the information processing device 110b controls the output device to output the acquired media data (S43). Further, independently of step S42a, the second wireless communication unit 453 of the information processing apparatus 110b performs content synchronization processing with the emergency information 411 and the access information 415 as content to be synchronized (S46).

  FIG. 13 is a flowchart showing the flow of processing of the wireless communication terminal 31 according to the third embodiment. The processing of the wireless communication terminal 36 is similar.

  First, the data synchronization application 310 of the wireless communication terminal 31 performs the content synchronization process, as in step S46 described above (S51). Then, the data synchronization application 310 determines whether or not the acquired content is access information (S52). When the acquired content is access information, the data synchronization application 310 acquires the media data 241 from the server 24 via the communication network N based on the received access information (S53). Then, the data synchronization application 310 controls the output device to output the obtained media data (S55). When it is determined in step S52 that the acquired content is not access information, the data synchronization application 310 determines whether the acquired content is media data (S54). If the acquired content is media data, the process proceeds to step S55. On the other hand, when the acquired content is not media data, the data synchronization application 310 performs normal processing according to the acquired content (S56). Then, it returns to step S51 and repeats steps S51 to S56.

  Next, a case in which the emergency information transmitted from the control station 21a propagates to the wireless communication terminals 31 and 36 will be described with reference to the sequence diagrams of FIGS. 14 and 15. First, the control station 21a generates a first wireless signal including emergency information to be notified and transmits it to the communication satellite 22 (S201). In response to this, the communication satellite 22 receives the first wireless signal from the control station 21a, and transmits, that is, relays the first wireless signal toward the ground such as the emergency vehicles 10a and 10b. Then, the first wireless communication unit 451 of the information processing devices 110a and 110b receives the first wireless signal from the communication satellite 22 via the GNSS antennas 130a and 130b and extracts the emergency information from the first wireless signal. .. Since the processing in the information processing device 110b is the same as that in FIG. 8, here, the processing in the information processing device 110a will be described.

  The instruction unit 454 of the information processing apparatus 110a issues a collection instruction to the mobile photographing apparatus 23 in response to the reception of the emergency information (S211). In response to this, the mobile photographing device 23 moves to the vicinity of the disaster site and collects media data by performing photographing and the like (S212). Then, the mobile photographing device 23 transmits the collected media data to the information processing device 110a. Then, the acquisition unit 455 of the information processing device 110a acquires media data from the mobile photographing device 23 (S213).

  Subsequently, the output control unit 452 of the information processing device 110a controls the output device 120 to output the acquired media data (S214). In response to this, the output device 120 outputs the output information (S215).

  Further, the registration unit 456 of the information processing device 110a registers the media data in the server 24 via the communication network N (S216). Then, the server 24 registers the media data received from the information processing apparatus 110a via the communication network N in the media data 241 (S217). Then, the registration unit 456 acquires access information to the media data 241 from the server 24 via the communication network N (S218).

  After that, the second wireless communication unit 453 of the information processing device 110a sets the emergency information 411 and the access information 415 as contents to be synchronized (S219). After that, the second wireless communication unit 453 establishes a wireless connection with the wireless communication terminal 31 (S220) and exchanges the content list with the wireless communication terminal 31 (S221). Then, in response to the content request from the wireless communication terminal 31, the second wireless communication unit 453 transmits a second wireless signal including emergency information and access information to the wireless communication terminal 31 (S222). .. In response to this, the data synchronization application 310 of the wireless communication terminal 31 acquires the media data corresponding to the access information included in the received second wireless signal, and outputs the emergency information and the acquired media data.

  Subsequently, in FIG. 15, as described above, the information processing apparatus 110b receives the first wireless signal from the communication satellite 22 and extracts the emergency information from the first wireless signal in step S201. In addition, the control station 21a periodically monitors the storage device 240 of the server 24 via the communication network N, and when detecting that the media data 241 is registered, the control station 21a transmits the media data from the server 24 via the communication network N. The access information to 241 is acquired (S231). Then, the control station 21a notifies the information processing apparatus 110b of the acquired access information via the communication network N (S232). It is assumed that the control station 21a holds in advance access information of the information processing apparatus 110a and the information processing apparatus 110b on the communication network N.

  Then, the acquisition unit 455 of the information processing device 110b transmits a media data acquisition request to the server 24 via the communication network N based on the received access information (S233). Then, the acquisition unit 455 acquires the media data corresponding to the access information from the server 24 via the communication network N (S234). As a result, the information processing device 110b can acquire the media data collected by the mobile photographing device 23. Then, the output control unit 452 of the information processing device 110b controls the output device 120 to output the acquired media data (S235). In response to this, the output device 120 outputs the output information (S236).

  After that, the second wireless communication unit 453 of the information processing device 110b sets the emergency information 411 and the access information 415 as contents to be synchronized (S237). After that, the second wireless communication unit 453 establishes a wireless connection with the wireless communication terminal 36 (S238), and exchanges the content list with the wireless communication terminal 36 (S239). Then, in response to the content request from the wireless communication terminal 36, the second wireless communication unit 453 of the information processing device 110b sends a second wireless signal including emergency information and access information to the wireless communication terminal 36. It is transmitted (S240). In response to this, the data synchronization application 360 of the wireless communication terminal 36 acquires the media data corresponding to the access information included in the received second wireless signal, and outputs the emergency information and the acquired media data.

  Here, in the present firefighting system, it takes time from the 119th call to the manual operation because the 119th call is followed by dispatching after determining the location, dispatching and dispatching. Also, it takes time because a fire engine must contact the center and wait for a command from the center before it can be re-mobilized after the end of another activity.

  On the other hand, in the third embodiment, for example, new emergency information can be notified in real time to an emergency vehicle that is engaged in a case (fire fighting, etc.) activity at another location. You can go straight to the emergency information site. Therefore, rescue activities can be performed quickly and efficiently. This is especially effective when the site is near.

  Further, according to the third embodiment, the media data 241 registered in the server 24 can be shared by other information systems. Therefore, it is possible to grasp the accurate situation of the disaster site in real time and utilize it in various ways by each related organization to respond more swiftly and appropriately.

  The server 24 and the storage device 240 in FIG. 9 may be a server group and a storage group in the cloud system connected to the communication network N. Then, in addition to the media data 241, the storage group may store sensor values acquired by various sensors, map information generated in advance by these, and the like. In that case, the acquisition unit 455 may acquire the sensor value, the map information, or the like corresponding to the position information included in the emergency information 411 from the storage group via the communication network N. Then, the output control unit 452 may generate output information based on the emergency information 411, the media data 414, the sensor value and the map information, and output the output information from the display device 121. Similarly, the second wireless communication unit 453 may transmit the emergency information 411, the media data 414, the sensor value, and the map information included in the second wireless signal.

  Further, in the present embodiment, in addition to the media information collecting device, cameras, sensors, etc. installed in various places may be used. For example, it is assumed that the camera and the water level sensor installed in the river are connected to the communication network N by wired or wireless communication. In that case, the camera can register the captured video around the river in the storage group of the cloud system via the communication network N. Further, the water level sensor can register the water level data measured from the river in the storage group of the cloud system via the communication network N. Furthermore, map information such as a hazard map around the river may be registered in advance in the storage group.

  Further, in this case, the instruction unit 454 may instruct the camera and the water level sensor installed in the river to collect the image data and the sensor value by wireless communication and to register the image data and the sensor value in the storage group of the cloud system. In that case, the registration of the media data by the registration unit 456 can be omitted.

  Alternatively, cameras, sensors, and the like installed in various places may always register sensor values such as images and water level data in the storage group of the cloud system via the communication network N. In this case, the control station 21a specifies the camera and the water level sensor installed in the area corresponding to the emergency information 411 together with the transmission of the emergency information 411. Then, the control station 21a acquires the second access information indicating the access destination of the video or the like registered in the storage group of the cloud system from the specified camera or the like. Then, the control station 21a notifies the information processing apparatuses 110a and 110b of the second access information via the communication network N, for example, as in step S232 of FIG. In that case, the acquisition unit 455 of the information processing apparatuses 110a and 110b receives the second access information, and based on the second access information, the video in the area corresponding to the emergency information 411 from the storage group via the communication network N. And water level data can be acquired. Therefore, the acquisition unit 455 of the information processing devices 110a and 110b may have at least a function corresponding to the above-described second acquisition unit.

  As a result, the emergency vehicles 10a and 10b can acquire images, water level data, hazard maps, etc. from the storage group via the communication network N based on the received emergency information 411. As a result, more detailed information on the disaster site can be acquired and propagated in real time and utilized.

<Embodiment 4>
The fourth embodiment is an application example of the first to third embodiments described above. FIG. 16 is a block diagram showing the configuration of the emergency information notification system 3000 according to the fourth embodiment. The emergency information notification system 3000 includes, for example, a passenger car 10c. The passenger car 10c is an example of a moving body, and may be a general passenger car, a bus, or a taxi. The passenger car 10c includes an information processing device 110c, an output device 120c, and a GNSS antenna 130c. That is, the information processing device 110c is not limited to an emergency vehicle, but may be installed in a general passenger vehicle, for example, as a car navigation system. As a result, the driver of the passenger car 10c or the like can be notified of the emergency information quickly. Moreover, before the emergency vehicle arrives at the disaster site, it is possible to promptly notify the nearby wireless communication terminals of the emergency information.

  Further, the emergency information notification system 3000 may include, for example, the rescue robot 10d. The rescue robot 10d is an example of a moving body, and includes an information processing device 110d, an output device 120d, and a GNSS antenna 130d. That is, the information processing device 110d may be mounted not only on an emergency vehicle but also on a robot that operates autonomously or by wireless operation for disaster rescue. As a result, emergency information can be promptly notified even to a person who cannot reach an emergency vehicle due to the collapse of a road or the like, or a place where a rescue team cannot reach because of a danger.

  The emergency information notification system 3000 may include, for example, the electronic display device 10e. The electronic display device 10e is a digital signage, a vending machine, or the like, and includes an information processing device 110e, an output device 120e, and a GNSS antenna 130e. Here, the output device 120e may be a display such as a digital signage or a vending machine. Thus, when the electronic display device 10e is installed near the disaster site, it is possible to promptly notify the emergency information through the wireless communication terminal possessed by the person viewing the electronic display device 10e.

  Further, the emergency information notification system 3000 may include, for example, the traffic control device 10f.
