Description

[Technical Field]

[0001] The present invention relates to a disaster-related information providing system, and is particularly suitable for use in a system that provides at least one of natural disaster-related information that should be reported regarding natural disasters and fire-related information that should be reported regarding fires. [Background technology]

[0002] Conventionally, when a natural disaster such as an earthquake, flood, or typhoon occurs, the Japan Meteorological Agency or a Meteorological Service Support Center working in cooperation with the Japan Meteorological Agency transmits warning information to broadcasting stations and telecommunications carriers (such as mobile phone operators), and based on the warning information, the warning is sent to devices such as televisions, radios, mobile phones, and smartphones. Here, if the target of the warning is limited to a specific area, the warning is sent only to devices within the target area. For this reason, if the manager of a building within the target area is located in a remote location outside the target area, the warning is not sent to the manager's device, which is an issue. Therefore, there is a need to be able to send warnings for the target area to the devices of managers in remote locations as well.

[0003] On the other hand, there are also systems that sound an alarm when a fire is detected by a fire alarm system installed in a building and notify the disaster prevention center in the building of the alarm information. However, even with this type of system, there is a problem in that the alarm is not notified to the terminal of the manager outside the building, so there is a need to notify the alarm issued by the building's fire alarm system to the terminal of the manager outside the building as well.

[0004] There is known a system that transmits emergency information based on the occurrence of an earthquake and emergency information based on the occurrence of a fire to a terminal via a communication network and displays the emergency information on the terminal (see, for example, Patent Documents 1 and 2).

[0005] In the emergency information network display system described in Patent Document 1, a server receives external signals related to emergency information such as emergency earthquake alerts and fire alarms, and displays and communicates emergency information on client terminals on the network by sending display command signals of audio and images (images notifying of an earthquake or fire, images notifying the location of a fire, images encouraging disaster prevention actions, etc.).

[0006] In the network-based emergency evacuation guidance system described in Patent Document 2, emergency information such as earthquakes and fires issued from J-Alert receiving equipment or earthquake detectors and fire alarm equipment installed in hotels and other accommodation facilities is converted into HTTP protocol on a server, and the emergency information converted into HTTP protocol is sent as a push notification to the tablets of facility users. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-113472 [Patent Document 2] Patent Publication No. 2021-15542 Summary of the Invention [Problem to be solved by the invention]

[0008] Patent Documents 1 and 2 describe that when an earthquake is detected, emergency information based on the earthquake is displayed, whereas when a fire is detected, emergency information based on the fire is displayed. However, they do not describe in detail how to specifically display emergency information when both an earthquake and a fire have occurred. For example, it is quite conceivable that an earthquake will occur during a fire, and it is also quite conceivable that an earthquake will cause a fire. In such cases, it is necessary to appropriately provide information about the earthquake and information about the fire.

[0009] The present invention has been made to solve such problems, and aims to be able to provide appropriate information related to natural disasters and information related to fires when both natural disasters such as earthquakes and fires occur. [Means for solving the problem]

[0010] In order to solve the above-mentioned problems, the present invention generates disaster-related information including at least one of natural disaster-related information about content to be reported regarding natural disasters and fire-related information about content to be reported regarding fires, based on at least one of natural disaster event information acquired from an external source via a communication network and fire event information acquired from a fire alarm system that monitors fires in a specified monitoring area, and transmits the generated disaster-related information to a terminal. Here, when it is presumed that the impact of a natural disaster related to the natural disaster event information and the impact of a fire related to the fire event information are occurring simultaneously, the generated disaster-related information is configured to display both the natural disaster-related information and the fire-related information simultaneously on the terminal. [Effects of the Invention]

[0011] According to the present invention configured as described above, when it is presumed that the effects of a fire and a natural disaster are occurring simultaneously, such as when an earthquake occurs during a fire or when a fire occurs due to an earthquake, both fire-related information that should be reported regarding the fire and natural disaster-related information that should be reported regarding the natural disaster are simultaneously displayed on the terminal. This allows the user of the terminal to quickly take appropriate action in response to both the fire and the natural disaster based on the displayed disaster-related information. Thus, according to the present invention, when both a fire and a natural disaster such as an earthquake occur, it is possible to appropriately provide the user of the terminal with fire-related information and natural disaster-related information that enables them to take appropriate action.

DETAILED DESCRIPTION OF THE INVENTION

[0013] (First embodiment) A first embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a diagram showing an example of the overall configuration of a disaster-related information provision system according to the first embodiment. As shown in Fig. 1, the disaster-related information provision system 1 according to the first embodiment is configured to include a natural disaster warning system 10, a fire alarm system 20, and a disaster information integration system 30.

[0014] When a natural disaster such as an earthquake, tsunami, flood, or typhoon occurs, the natural disaster warning system 10 acquires natural disaster event information related to the occurrence of the natural disaster from the Meteorological Service Support Center in cooperation with the Japan Meteorological Agency, the J-Alert system, and the like, generates event information for a predetermined area unit, and provides this information to the disaster information integration system 30. The predetermined area unit is, for example, a facility unit. A facility may be a single building, or a comprehensive facility including multiple buildings.

[0015] That is, when the natural disaster warning system 10 acquires natural disaster event information relating to the occurrence of a natural disaster in a specific region, it generates natural disaster event information for each facility belonging to that region and provides the information together with a facility ID that uniquely identifies each facility to the disaster information integration system 30. The specific configuration of this natural disaster warning system 10 and the details of the natural disaster event information will be described later.

[0016] The fire alarm system 20 includes a communication device 21 and a fire receiver 22, and also includes a plurality of sensors 23 in a predetermined monitoring area. -1 ,twenty three -2 , and a plurality of transmitters 24 -1 ,twenty four -2 The system includes fire terminals such as , , , etc., and a fire receiver 22 connected to the fire terminals via a transmission line or the like monitors fires in a specified monitoring area. The specified monitoring area is, for example, an area on a facility-by-facility basis. The multiple fire terminals are installed in different locations within a facility. For example, the multiple fire terminals are installed in each room, corridor, etc. within the facility. Each fire terminal is responsible for its own monitoring area, and the multiple fire terminals cover the monitoring area on a facility-by-facility basis.

[0017] Multiple detectors 23 -1 ,twenty three -2 , detect predetermined physical quantities related to a fire, such as smoke density, and periodically transmit the detected physical quantities to the fire receiver 22. -1 ,twenty four -2 ,··· is operated in the event of a fire, and transmitter 24 -1 ,twenty four -2, . . . are operated, the fire receiver 22 periodically transmits a signal indicating that the fire detector 23 -1 ,twenty three -2 , . . . , . . . If the predetermined physical quantity received from one or more of the transmitters 24 satisfies the condition of a fire occurrence (which may include the occurrence of a fire warning sign), the fire event information, which is disaster information for a predetermined area unit, is generated and provided to the disaster information integration system 30 together with the facility ID via the communication device 21. -1 ,twenty four -2 , ... -1 ,twenty four -2 When an operation signal of ,... is received, fire event information, which is disaster information for a predetermined area unit, is generated and provided to the disaster information integration system 30 together with the facility ID via the communication device 21. This fire event information includes, for example, flag information indicating that a fire has occurred or that there are signs of a fire, and information such as the location of the fire. Furthermore, when fire recovery is complete (when it can be confirmed that the fire has been extinguished or there is no fire), the fire alarm system 20 issues fire event information indicating recovery completion and provides it to the disaster information integration system 30.

[0018] The predetermined area unit for fire event information is the same as for natural disaster event information, for example, a facility unit. A facility may be a single building or a comprehensive facility including multiple buildings. The facility ID used by the fire alarm system 20 is the same as the facility ID used by the natural disaster warning system 10, and the same facility ID is assigned to the same facility.

[0019] The disaster information integration system 30 is composed of a disaster information integration server 30A that handles multiple facilities and a terminal information providing server 30B that is provided for each facility. The disaster information integration server 30A and the terminal information providing server 30B are connected via a communication network such as the Internet.

[0020] The disaster information integration server 30A acquires natural disaster event information for each facility from the natural disaster warning system 10, and acquires fire event information for each facility from the fire alarm system 20. When the disaster information integration server 30A acquires at least one of natural disaster event information and fire event information, the terminal information providing server 30B generates at least one of natural disaster-related information that should be reported regarding the natural disaster and fire-related information that should be reported regarding the fire, and transmits the disaster-related information including at least one of the natural disaster-related information and the fire-related information to the user terminals 41, 42, 43. The specific configuration of the disaster information integration system 30 will be described later.

[0021] The user terminals 41, 42, and 43 are terminals that receive disaster-related information from the disaster information integration system 30 and display it on a display, and are configured, for example, as smartphones, tablets, or personal computers. Users who use the user terminals 41, 42, and 43 include facility managers and patrol security guards at the facility. For convenience of explanation, the following description will be given assuming that the first user terminal 41 is used by the manager, the second user terminal 42 is used by the patrol security guard in charge of the first floor of the building, and the third user terminal 43 is used by the patrol security guard in charge of the second floor of the building. Note that the users who use the user terminals 41, 42, and 43 may be facility users who have installed a facility-specific application.

[0022] Fig. 2 is a block diagram showing an example of the functional configuration of the natural disaster warning system 10 according to the first embodiment. As shown in Fig. 2, the natural disaster warning system 10 includes, as its functional configuration, a natural disaster event information acquisition unit 11, a facility-level event information generation unit 12, and a facility-level event information transmission unit 13. The natural disaster warning system 10 also includes, as a storage medium, a facility information storage unit 100.

[0023] The functional blocks 11 to 13 can be configured by any of hardware, a DSP (Digital Signal Processor), and software. For example, when configured by software, the functional blocks 11 to 13 are actually configured with a CPU, RAM, ROM, etc. of a computer, and are realized by the operation of a program stored in a storage medium such as the RAM, ROM, hard disk, or semiconductor memory.

[0024] The natural disaster event information acquisition unit 11 acquires natural disaster event information related to the occurrence of natural disasters other than fires from an external source via a communication network. The external source may be the Japan Meteorological Service Support Center or the J-Alert system. Natural disasters refer to damage caused by abnormal natural phenomena such as strong winds, heavy rain, heavy snowfall, floods, storm surges, earthquakes, tsunamis, volcanic eruptions, and the like, and any of these may be applied to this embodiment. The following description focuses on earthquakes and tsunamis that accompany earthquakes as examples of natural disasters.

[0025] The natural disaster event information (hereinafter referred to as earthquake event information) acquired externally by the natural disaster event information acquisition unit 11 is earthquake information (including emergency earthquake warnings, earthquake early warnings, and other information) released by the Japan Meteorological Agency, and includes information such as the location of the earthquake (epicenter), the scale (magnitude) of the earthquake, the predicted seismic intensity and predicted arrival time of the earthquake for each specified region, whether or not a tsunami is likely to occur, the height of the tsunami, and the predicted arrival time of the tsunami. The predicted seismic intensity and predicted arrival time of the earthquake, whether or not a tsunami is likely to occur, the height of the tsunami, and the predicted arrival time of the tsunami are information on a region-by-region basis. Hereinafter, the earthquake event information acquired externally by the natural disaster event information acquisition unit 11 will be referred to as earthquake event information on a region-by-region basis.

[0026] The facility-based event information generation unit 12 generates earthquake event information for each facility based on the earthquake event information for each region acquired by the natural disaster event information acquisition unit 11. When generating earthquake event information for each facility, the facility-based event information generation unit 12 refers to facility information stored in the facility information storage unit 100. The facility information is database information including, for example, the facility ID of each facility, name information of each facility, and location information indicating the location of each facility. For each region indicated in the earthquake event information for each region, the facility-based event information generation unit 12 extracts facilities located in each region from the database information in the facility information storage unit 100, and generates earthquake event information for each extracted facility.

[0027] Earthquake event information for each facility may include, for example, information on the location of the earthquake, the magnitude of the earthquake, the expected seismic intensity for each facility, and the expected time of arrival of the earthquake, and in the case of facilities located in coastal areas, may further include information on the possibility of a tsunami occurring, the height of the tsunami, and the expected time of arrival of the tsunami.

[0028] For example, if the area-based earthquake event information includes information on area A, the facility-based event information generation unit 12 extracts facilities that exist in area A from the database information in the facility information storage unit 100, and generates facility-based earthquake event information for each extracted facility, including the expected seismic intensity and expected arrival time of the earthquake for area A (and, if area A is a coastal area, also the possibility of a tsunami occurring, the height of the tsunami, and the expected arrival time of the tsunami).If the area-based earthquake event information includes information on area B in addition to area A, facility-based earthquake event information is generated similarly for facilities in area B.

[0029] In this example, the earthquake event information for each facility in area A will all be the same. In this case, earthquake event information with the same content may be generated for each of the multiple facilities, or list information for multiple facilities may be added to one piece of earthquake event information. The list information may be composed of facility IDs or facility name information, for example. The same applies to the earthquake event information for each facility in area B.

[0030] The facility-level event information generation unit 12 may calculate the expected seismic intensity and expected arrival time of the earthquake for each facility based on the location of the earthquake and the magnitude of the earthquake included in the region-level earthquake event information and the location information of the facility stored in the facility information storage unit 100. Similarly, the facility-level event information generation unit 12 may calculate the expected tsunami height and expected arrival time of the tsunami for each facility based on the tsunami height and expected arrival time included in the region-level earthquake event information and the location information of the facility stored in the facility information storage unit 100. In this case, the facility-level earthquake event information generated for multiple facilities in region A may have different content for each facility. The same is true for facility-level earthquake event information generated for multiple facilities in region B.

[0031] The facility-level event information transmitter 13 transmits the facility-level earthquake event information generated by the facility-level event information generator 12 together with, for example, a facility ID to the disaster information integration server 30A of the disaster information integration system 30. The natural disaster warning system 10 and the disaster information integration server 30A are connected via a communication network such as the Internet or a LAN (Local Area Network).

[0032] Fig. 3 is a diagram illustrating an example of the functional configuration of the disaster information integration system 30 according to the first embodiment. As shown in Fig. 3, the disaster information integration system 30 includes, as its functional configuration, an individual natural disaster event information acquisition unit 31, a fire event information acquisition unit 32, a disaster-related information generation unit 33, and a disaster-related information transmission unit 34. The disaster information integration system 30 also includes, as storage media, a facility information storage unit 301 and a notification destination information storage unit 302. The disaster information integration server 30A includes the individual natural disaster event information acquisition unit 31 and the fire event information acquisition unit 32, and the terminal information provision server 30B includes the disaster-related information generation unit 33, the disaster-related information transmission unit 34, the facility information storage unit 301, and the notification destination information storage unit 302.

[0033] The functional blocks 31 to 34 can be configured by any of hardware, DSP, and software. For example, when configured by software, the functional blocks 31 to 34 are actually configured with a CPU, RAM, ROM, etc. of a computer, and are realized by the operation of a program stored in a recording medium such as the RAM, ROM, hard disk, or semiconductor memory.

[0034] The individual natural disaster event information acquisition unit 31 acquires earthquake event information for each facility from the natural disaster warning system 10. The fire event information acquisition unit 32 acquires fire event information for each facility from the fire alarm equipment 20 (fire event information according to the results of monitoring by the fire alarm equipment 20).

[0035] When at least one of earthquake event information and fire event information is acquired by at least one of the individual natural disaster event information acquisition unit 31 and the fire event information acquisition unit 32, the disaster-related information generation unit 33 generates disaster-related information including at least one of earthquake-related information and fire-related information by generating at least one of earthquake-related information (equivalent to one aspect of the natural disaster-related information in the claims) containing content to be reported regarding an earthquake and fire-related information containing content to be reported regarding a fire. Here, earthquake event information is acquired by the individual natural disaster event information acquisition unit 31 when earthquake event information is acquired by the natural disaster event information acquisition unit 11 of the natural disaster warning system 10.

[0036] When only earthquake event information has been acquired by the individual natural disaster event information acquisition unit 31, the disaster-related information generation unit 33 generates only earthquake-related information and outputs this as disaster-related information to the disaster-related information transmission unit 34. On the other hand, when only fire event information has been acquired by the fire event information acquisition unit 32, the disaster-related information generation unit 33 generates only fire-related information and outputs this as disaster-related information to the disaster-related information transmission unit 34.

[0037] Here, earthquake-related information includes some or all of the information contained in the earthquake event information for each facility, such as the location of the earthquake, the magnitude of the earthquake, the expected seismic intensity and expected arrival time of the earthquake, whether or not a tsunami is likely to occur, the height of the tsunami, and the expected arrival time of the tsunami.In addition to the above information, earthquake-related information may also include information on countermeasures to be taken in the event of an earthquake.The countermeasure information is, for example, information on actions to be taken to ensure the safety of facility visitors in the event of an earthquake, actions to be taken to prevent the occurrence of secondary disasters, evacuation guidance methods, etc.This countermeasure information may be information in the form of text only, illustrations, or a combination of illustrations and text.

[0038] The information regarding evacuation guidance methods may include information regarding evacuation guidance directions within a facility. The information regarding evacuation guidance directions within a facility may be represented by a facility layout image showing the layout of the facility, with an arrow image indicating the evacuation guidance direction superimposed on top. When generating such information regarding evacuation guidance directions, the disaster-related information generation unit 33 references facility information stored in the facility information storage unit 301. This facility information is database information including, for example, the facility ID of each facility, the type and size of the facility, a facility layout image, and information regarding the structure of the facility. The information regarding the structure of the facility is information configured to enable identification of a route from each location within the facility to an exit or emergency exit, and includes layout information indicating the locations of each room, each corridor, each staircase, exits, emergency exits, etc.

[0039] The disaster-related information generation unit 33 acquires a facility layout image from the database information based on the facility ID acquired from the individual natural disaster event information acquisition unit 31, and generates information related to evacuation guidance directions by superimposing an arrow image indicating the evacuation guidance direction on the facility layout image. The arrow image used here may be an arrow image indicating the direction from a predetermined position within the facility to an exit or emergency exit. If the facility has a multi-story structure, information related to evacuation guidance directions may be generated by superimposing an arrow image at a predetermined position on the facility layout image for each floor.

[0040] FIG. 4 is a diagram illustrating an example of disaster-related information that includes only earthquake-related information. FIG. 4 shows disaster-related information displayed on a smartphone screen, and the entire disaster-related information can be displayed by scrolling by the user. In the example shown in FIG. 4, a message informing users of an earthquake occurs is followed by text at the top that indicates the epicenter, magnitude, expected seismic intensity, expected arrival time of the earthquake, and the possibility of a tsunami. Below this text, text displays instructions for actions visitors to the facility should take to ensure their own safety in the event of an earthquake and actions to take to prevent secondary disasters. Images of evacuation guidance directions are also displayed below that. In the example shown in FIG. 4, the facility is a multi-story building, and arrow images indicating evacuation guidance directions are superimposed on facility layout images for each floor.

[0041] The fire-related information includes alarm information that notifies of a fire or signs of a fire, and information on the location of the fire, which is generated based on flag information included in the fire event information for each facility. In addition to the above information, this fire-related information may also include information on countermeasures to be taken in the event of a fire. The countermeasure information is, for example, information on actions to be taken to ensure the safety of facility visitors in the event of a fire, actions to be taken to prevent the occurrence of secondary disasters, and evacuation guidance methods. This countermeasure information may be information in the form of text only, illustrations, or a combination of illustrations and text.

[0042] The information regarding evacuation guidance methods may include information regarding evacuation guidance directions within a facility. The information regarding evacuation guidance directions within a facility may be expressed as an arrow image indicating the evacuation guidance direction superimposed on a facility layout image showing the layout of the facility. In the case of earthquake-related information described above, the arrow image indicating the evacuation guidance direction is an image indicating the direction from a predetermined position on the facility layout image to an exit or emergency exit. In contrast, in the case of fire-related information, the information regarding evacuation guidance directions is generated by superimposing an arrow image on the facility layout image so as to indicate an evacuation guidance direction that guides people from the location of the fire within the facility (included in the fire event information) to the exit or emergency exit.

[0043] Figure 5 is a diagram showing an example of disaster-related information that includes only fire-related information. In the example shown in Figure 5, a text message informing visitors that a fire has occurred and the location of the fire are displayed at the top. Below this text, text is displayed explaining what actions visitors should take to ensure their own safety in the event of a fire and what actions should be taken to prevent secondary disasters, and below that, an image showing evacuation guidance directions is displayed. As in Figure 4, an image of an arrow indicating the evacuation guidance direction is superimposed on the facility layout image for each floor.

[0044] In addition, the disaster-related information generation unit 33 generates disaster-related information configured so that both the earthquake-related information and the fire-related information are displayed simultaneously on the user terminals 41, 42, and 43 when earthquake event information is acquired by the individual natural disaster event information acquisition unit 31 and fire event information is acquired by the fire event information acquisition unit 32, and it is inferred that the effects of an earthquake (including the effects of a tsunami) related to the earthquake event information and the effects of a fire related to the fire event information are occurring simultaneously.

[0045] The impact of an earthquake or a fire refers to, for example, the impact of an earthquake or a fire on a facility. The impact of an earthquake on a facility is that the facility shakes, which may cause damage such as damage or collapse. The impact of a fire on a facility is that the facility is burning. The impact of an earthquake or a fire may also include a situation in which the user of user terminal 41, 42, 43 must take some action in response to the occurrence of an earthquake or a fire. Actions that the user must take include actions to ensure the safety of facility visitors, actions to prevent the occurrence of secondary disasters, and evacuation guidance to a safe place. Therefore, a situation in which the impact of an earthquake and the impact of a fire occur simultaneously continues for a certain length of time from the occurrence of the earthquake or the occurrence of the fire.

[0046] For example, the disaster-related information generation unit 33 estimates that the situation in which the effects of the earthquake are occurring continues for a predetermined time from the occurrence of the earthquake, and estimates that the situation in which the effects of the fire are occurring continues for a predetermined time from the occurrence of the fire, and infers that the effects of the earthquake and the effects of the fire are occurring simultaneously during the period in which these estimated times overlap.

[0047] The length of time that an earthquake or fire will affect a facility may vary depending on the earthquake or fire conditions, the location, size, and structure of the facility, etc. Furthermore, the actions that should be taken to ensure the safety of facility visitors, the actions that should be taken to prevent secondary disasters, and the time required to evacuate to a safe location may also vary depending on the earthquake or fire conditions, the type and size of the facility, etc. Therefore, the disaster-related information generation unit 33 may calculate the length of the predetermined time during which the impact of an earthquake or fire is estimated to be occurring based on a predetermined function, depending on the earthquake or fire conditions indicated in the earthquake event information or fire event information, the type and size of the facility stored in the facility information storage unit 301, etc.

[0048] Figure 6 is a diagram showing an example of disaster-related information that includes both earthquake-related information and fire-related information. In the example of Figure 6, following a message informing users that an earthquake and a fire have occurred, information about the earthquake (epicenter, magnitude, predicted seismic intensity, predicted time of arrival of the earthquake, possibility of tsunami occurrence) and information about the fire (location of the fire) are displayed in text form at the top. Below this text, actions that visitors to the facility should take to ensure their own safety in the event of an earthquake or fire and actions that should be taken to prevent secondary disasters are displayed in text form, and further below that, an image showing evacuation guidance directions is displayed.

[0049] In this embodiment, when the disaster-related information generating unit 33 generates disaster-related information configured so that both earthquake-related information and fire-related information are simultaneously displayed on the user terminals 41, 42, and 43 as shown in Fig. 6, the disaster-related information generating unit 33 may generate disaster-related information configured so that the earthquake-related information and the fire-related information can be distinguished from each other. In this way, the user can easily recognize which of the earthquake-related information and the disaster-related information displayed simultaneously is earthquake-related information and which is disaster-related information.

[0050] For example, as shown in Fig. 6, earthquake-related information and fire-related information may be displayed in the same area, but distinguishable by different text or background colors. Earthquake-related information may also be distinguishable from tsunami-related information. Furthermore, as shown in Fig. 6, arrow images indicating evacuation directions may be displayed overlaid on a facility layout image, and arrow images 61A-61D relating to earthquake-related information and arrow images 62A-62D relating to fire-related information may be displayed in different display modes (colors, patterns, shapes, etc.).

[0051] As another example, an area for displaying earthquake-related information and an area for displaying fire-related information may be provided independently, allowing each area to be checked simultaneously. For example, the display area may be divided into two, horizontally or vertically, to simultaneously display earthquake-related information and fire-related information.

[0052] The disaster-related information generation unit 33 supplies the disaster-related information generated as described above to the disaster-related information transmission unit 34 and instructs it to transmit the information to the user terminals 41, 42, and 43. At this time, the disaster-related information generation unit 33 references the notification destination information stored in the notification destination information storage unit 302 to identify the address information of the user terminals 41, 42, and 43 to which the disaster-related information should be transmitted. The notification destination information is, for example, database information including the facility ID of each facility, the address information of the user terminals 41, 42, and 43 associated with each facility ID, and the attributes of the users using the user terminals 41, 42, and 43 (either facility manager or patrol security guard). The disaster-related information generation unit 33 references the notification destination information storage unit 302 based on the facility ID acquired from the individual natural disaster event information acquisition unit 31 or the fire event information acquisition unit 32 to identify the address information of the user terminals 41, 42, and 43 to which the disaster-related information should be transmitted, and supplies the disaster-related information together with the address information to the disaster-related information transmission unit 34.

[0053] The disaster-related information transmission unit 34 transmits the disaster-related information generated by the disaster-related information generation unit 33 to the user terminals 41, 42, 43 whose address information was identified by the disaster-related information generation unit 33 via a communication network. The disaster information integration system 30 and the user terminals 41, 42, 43 are connected via a communication network such as the Internet or a mobile phone network. The user terminals 41, 42, 43 that receive the disaster-related information from the disaster information integration system 30 display the disaster-related information on their displays.

[0054] As described above in detail, according to the first embodiment, when it is presumed that the effects of a natural disaster and a fire are occurring simultaneously, such as when an earthquake occurs during a fire or when a fire occurs due to an earthquake, both natural disaster-related information that should be reported regarding the natural disaster and fire-related information that should be reported regarding the fire are simultaneously displayed on the user terminals 41, 42, and 43. This enables the users of the user terminals 41, 42, and 43 to quickly take appropriate action against both the earthquake and the fire based on the displayed disaster-related information. The same applies to natural disasters other than earthquakes. Thus, according to the present embodiment, when both a natural disaster such as an earthquake and a fire occur, natural disaster-related information and fire-related information that enable the users of the user terminals 41, 42, and 43 to take appropriate action can be appropriately provided.

[0055] <Modification 1 of the First Embodiment> In the first embodiment, a priority display setting may be made for any of the various pieces of information to be displayed as disaster-related information, and the display may be controlled according to the setting. In this case, the disaster-related information generating unit 33 generates disaster-related information in which the priority display setting is applied to the information to be prioritized, and the disaster-related information transmitting unit 34 transmits the disaster-related information with the setting to the user terminals 41, 42, and 43. Here, the information to be prioritized for display may be set in advance in the disaster-related information generating unit 33, for example. Alternatively, the administrator may access the disaster information integration system 30 from the user terminal 41 to set the priority display.

[0056] For example, information set as the target for top priority display (e.g., predicted earthquake arrival time, predicted tsunami arrival time, location of fire, etc.) may be configured to continue to be displayed on the screen without scrolling out. When there is a plurality of pieces of information set as the target for priority display, they may all be displayed at the same time with priority, or they may be displayed one by one according to a pre-set priority. Displaying one by one means that only the information with the highest priority is displayed one by one, and when the user performs an operation to instruct the display of the next piece of information, the information with the next priority is displayed.

[0057] When setting priorities, it is preferable to set high-priority earthquake information (such as the predicted earthquake arrival time and the predicted tsunami arrival time) as the highest-priority display information among the priority display information. In other words, it is preferable to set the predicted earthquake arrival time and the predicted tsunami arrival time as the highest-priority display information because there is a short grace period from the announcement of a prediction until the actual occurrence of an earthquake or tsunami, and because damage can be greatly reduced by taking prompt protective measures.

[0058] Furthermore, instead of a user setting the priority display, the priority display may be dynamically set based on the contents of the earthquake event information and the fire event information. For example, the disaster-related information generation unit 33 calculates a priority score using a predetermined function based on the magnitude and epicenter included in the earthquake event information and the location information of the facility stored in the facility information storage unit 301 (calculating the distance from the epicenter to the facility), and sets one of the earthquake information items as a target for priority display if the priority score exceeds a threshold. A priority score is similarly calculated for the fire event information, and if the priority score exceeds a threshold, sets one of the information items as a target for priority display.

[0059] Here, with regard to fire-related information, the oldest priority display information may be displayed preferentially until the fire is restored (until it is confirmed that the fire has been extinguished or there is no fire). This is to make it easier to identify the source of the fire by understanding the first report of the fire. In this case, after the disaster-related information generation unit 33 generates disaster-related information to which a priority display setting has been assigned for any of the fire-related information, the fire event information acquisition unit 32 does not generate disaster-related information to which a priority display setting has been assigned for any of the fire event information acquired by the fire event information acquisition unit 32 from the fire alarm system 20 until the fire event information acquisition unit 32 receives fire event information indicating that the fire has been restored from the fire alarm system 20.

[0060] In contrast, for earthquake-related information, it is preferable to dynamically change the priority display setting based on the latest earthquake event information. This is because it is desirable to prioritize the latest information in accordance with changes in the situation. In this case, the disaster-related information generation unit 33 calculates a priority score each time the individual natural disaster event information acquisition unit 31 acquires earthquake event information, and whenever the priority score exceeds a threshold, generates disaster-related information with a priority display setting. The disaster-related information transmission unit 34 transmits the disaster-related information generated by the disaster-related information generation unit 33 with the priority display setting to the user terminals 41, 42, and 43. When disaster-related information with the priority display setting is received, the user terminals 41, 42, and 43 display the most recent disaster-related information with the priority display setting instead of the disaster-related information that had been prioritized up until then.

[0061] Furthermore, the setting and cancellation of the priority display described above may be dynamically performed depending on the situation in which the effects of an earthquake or a fire are estimated to be occurring. For example, if it is estimated based on earthquake event information that the impact of an earthquake on a facility will be within a predetermined time (for example, if the earthquake information indicates that the predicted tsunami arrival time is within a predetermined time), the predicted tsunami arrival time is set as the target for priority display. On the other hand, when a second predetermined time has passed since the predetermined time when it is estimated that the earthquake will affect the facility, the setting of the priority display is cancelled. Here, the setting of the priority display is automatically cancelled, but it may also be cancelled manually by the user.

[0062] In this way, damage caused by a potential future disaster can be avoided by preferentially displaying the information set as the target for priority display until the type of damage can be confirmed. Furthermore, if the damage situation can be confirmed within a second predetermined time after the actual occurrence of a disaster, it is considered that the information set as the target for priority display no longer needs to be preferentially displayed, and the priority display setting is cancelled. Note that the display method may be as described above when there are multiple pieces of information set as the target for priority display, such as when the next disaster-related information is generated with the priority display setting before the priority display setting for a certain disaster-related information is cancelled.

[0063] <Modification 2 of the First Embodiment> In the first embodiment, when the evacuation guidance direction of the earthquake-related information conflicts with the evacuation guidance direction of the fire-related information, the disaster-related information generating unit 33 may generate disaster-related information including information indicating the conflict. By generating disaster-related information including the information indicating the conflict and displaying it on the user terminals 41, 42, and 43, the user can be notified that a situation requires a decision as to which direction to evacuate.

[0064] For example, in the example of disaster-related information shown in FIG. 6, the evacuation guidance direction of the earthquake-related information indicated by arrow image 61D conflicts with the evacuation guidance direction of the fire-related information indicated by arrow image 62D. That is, because the presence or absence of a fire cannot be determined from earthquake event information alone, the evacuation guidance arrow images 61A-61D generated based on the earthquake event information may include arrows pointing toward the location of the fire. On the other hand, the evacuation guidance arrow images 62A-62D generated based on the fire event information all encourage people to move away from the location of the fire. Therefore, a conflict may arise between the evacuation guidance direction of the earthquake-related information and the evacuation guidance direction of the fire-related information.

[0065] Furthermore, when a large-scale earthquake occurs, there is a risk that a fire and a tsunami may occur simultaneously or consecutively. In this case, the disaster-related information generation unit 33 may generate an arrow image indicating a direction to evacuate from the fire location based on the fire event information acquired by the fire event information acquisition unit 32 from the fire alarm system 20, while generating an arrow image indicating a direction to evacuate to a higher location within the facility to escape the tsunami based on the earthquake event information acquired by the individual natural disaster event information acquisition unit 31. In this case, too, there is a possibility that the evacuation guidance directions of the earthquake-related information and the fire-related information may conflict with each other.

[0066] When a conflict occurs in this way, the arrow image for the earthquake-related information and the arrow image for the fire-related information are displayed in different display modes, and a message, illustration, or the like is displayed to indicate that a conflict has occurred between the arrow images, thereby making it possible to clearly alert the user. Here, the disaster-related information generating unit 33 may generate disaster-related information configured so that the information on the conflicting part between the evacuation guidance directions of the fire-related information and the evacuation guidance directions of the natural disaster-related information can be distinguished from other information.

[0067] In the example of disaster-related information shown in FIG. 6, this corresponds to the portion where an arrow image 61D indicating an evacuation guidance direction for earthquake-related information and an arrow image 62D indicating an evacuation guidance direction for fire-related information conflict with each other. In this case, the disaster-related information generator 33 generates disaster-related information configured so that the two arrow images 61D, 62D can be distinguished from other information. For example, the conflicting arrow images 61D, 62D can be made more noticeable by making them larger than the non-conflicting arrow images 61A-61C, 62A-62C, or by adding a background color. Instead of or in addition to displaying the arrow images 61D, 62D larger, they may be displayed flashing.

[0068] In addition, when it is desirable to evacuate to a higher floor of a facility, such as in response to a tsunami, this may conflict with other evacuation directions for leaving the facility. In this case, the arrow image indicating the evacuation direction for fire-related information will be displayed as a downward arrow near the stairs, and the arrow image indicating the evacuation direction for natural disaster-related information will be displayed as an upward arrow near the stairs. In this case, the display will be similar to that described above when evacuation directions conflict.

[0069] In the example of Fig. 6, both arrow images 61A-61C indicating the evacuation guidance direction for earthquake-related information and arrow images 62A-62C indicating the evacuation guidance direction for fire-related information are displayed even in areas where there is no conflict in the evacuation guidance direction. In contrast, only one arrow image may be displayed in areas where there is no conflict in the evacuation guidance direction. In this way, it is possible to configure the information (two arrow images 61D, 62D) in areas where there is a conflict between the evacuation guidance direction for fire-related information and the evacuation guidance direction for natural disaster-related information to be distinguishable from other information.

[0070] 6, even in areas where there is no conflict in evacuation guidance directions, it is possible to emphasize that there is no conflict by displaying two arrow images 61A-61C and 62A-62C side by side, so that the user can evacuate safely in the direction indicated by the arrow image.

[0071] Furthermore, when the evacuation guidance directions in the earthquake-related information and the fire-related information conflict with each other, the following processing may be performed. That is, the disaster-related information generation unit 33 generates first disaster-related information that includes information indicating a conflict but does not include information on the evacuation guidance directions, and second disaster-related information that includes the evacuation guidance directions in the earthquake-related information and the fire-related information. After transmitting the first disaster-related information to the user terminals 41, 42, and 43, the disaster-related information transmission unit 34 transmits the second disaster-related information upon receiving a display request from the user of the user terminal 41, 42, or 43 to which the first disaster-related information was transmitted.

[0072] FIG. 7 is a diagram showing an example of first disaster-related information. As shown in FIG. 7, the first disaster-related information does not include information on evacuation guidance directions, which is formed by superimposing an arrow image on a facility layout image. Instead of the information on evacuation guidance directions, a message 71 indicating that there is a conflict and a display button 72 for requesting the display of information including the conflict are displayed. When the user operates this display button 72, the disaster-related information transmission unit 34 transmits disaster-related information such as that shown in FIG. 6 generated by the disaster-related information generation unit 33 to the user terminals 41, 42, and 43. This disaster-related information shown in FIG. 6 corresponds to the second disaster-related information. In this way, by displaying the first disaster-related information before displaying the second disaster-related information, it is possible to strongly impress upon the user that a conflict has occurred.

[0073] <Modification 3 of the First Embodiment> Furthermore, in the first embodiment, it may be possible to enable or disable only a predetermined evacuation guidance display based on processing by a user with higher authority (e.g., a facility manager) among multiple users who use the user terminals 41, 42, and 43. For example, with regard to evacuation guidance display in the event of a fire, it is possible to enable the display of only evacuation guidance routes in the vicinity of the fire location. Alternatively, it is also possible to enable only one of multiple evacuation guidance directions.

[0074] <Fourth Modification of the First Embodiment> Furthermore, in the first embodiment, the display of disaster-related information may be terminated by transmitting end event information from the user terminal 41, 42, or 43 currently displaying the disaster-related information to the terminal information providing server 30B of the disaster information integration system 30. Even if end event information is not received from the user terminal 41, 42, or 43, the display of disaster-related information may be automatically terminated when a predetermined condition is met. For example, in the case of a fire, it may take a long time for the fire alarm system 20 to issue fire event information indicating the occurrence of a fire and then issue fire event information indicating the completion of recovery. In this case, the display of fire-related information may continue even though the fire has actually ended, which is undesirable. Therefore, the display of fire-related information may be automatically terminated when a predetermined time has elapsed since the fire event information indicating the occurrence of a fire was issued.

[0075] <Fifth Modification of the First Embodiment> Furthermore, in the first embodiment, the disaster-related information generation unit 33 may generate attribute-specific disaster-related information with different content depending on the attributes of the users of the user terminals 41, 42, and 43, and the disaster-related information transmission unit 34 may transmit the attribute-specific disaster-related information generated by the disaster-related information generation unit 33 to each of the user terminals 41, 42, and 43 whose user attributes match.

[0076] For example, the disaster-related information generation unit 33 may generate different disaster-related information depending on the facility manager, the patrol security guard in charge of the first floor of the facility, and the patrol security guard in charge of the second floor of the facility. In this case, the disaster-related information transmission unit 34 transmits the disaster-related information generated for the facility manager to the first user terminal 41, the disaster-related information generated for the patrol security guard in charge of the facility to the second user terminal 42, and the disaster-related information generated for the facility users to the third user terminal 43. For example, it is possible to vary the content of the information on measures to be taken in the event of an earthquake or a fire depending on the facility manager, the patrol security guard in charge of the first floor of the facility, and the patrol security guard in charge of the second floor of the facility.

[0077] As one example, information regarding evacuation guidance directions may be displayed only on the first user terminal 41 used by the administrator. This is because evacuation may be carried out more smoothly if the evacuation guidance directions are visible only to the administrator. As another example, if a fire breaks out on the second floor, instructions regarding fire response (e.g., a message such as "Go to the source of the fire and check whether there is a fire or not") may be displayed on a user terminal intended for a worker responding on the second floor (e.g., user terminal 43 used by a patrol security guard in charge of the second floor), and instructions regarding fire support (e.g., a message such as "Please provide support for the fire response on the second floor. Please secure an evacuation route") may be displayed on a user terminal intended for a worker responding on a floor other than the second floor (e.g., user terminal 42 used by a patrol security guard in charge of the first floor).

[0078] 8, the disaster information integration system 30 may be configured to include a first processing unit 35A that generates disaster-related information for the administrator and transmits it to a first user terminal 41, a second processing unit 35B that generates disaster-related information for the patrol security guard who has jurisdiction over the first floor and transmits it to a second user terminal 42, and a third processing unit 35C that generates disaster-related information for the patrol security guard who has jurisdiction over the second floor and transmits it to a third user terminal 43. Each of the first to third processing units 35A to 35C includes a disaster-related information generation unit 33 and a disaster-related information transmission unit 34. In this way, processing efficiency can be improved by distributing the load.

[0079] (Second embodiment) Next, a second embodiment of the present invention will be described with reference to the drawings. Fig. 9 is a diagram showing an example of the overall configuration of a disaster-related information provision system 1' according to the second embodiment. In Fig. 9, components having the same functions as those shown in Fig. 1 are given the same reference numerals. As shown in Fig. 9, the disaster-related information provision system 1' according to the second embodiment includes a disaster information integration system 30' instead of the disaster information integration system 30.

[0080] 9, in addition to user terminals 41, 42, and 43, a digital signage 44 is connected to a terminal information providing server 30B' of a disaster information integration system 30' via a communication network. The terminal information providing server 30B' transmits disaster-related information to the user terminals 41, 42, and 43 as well as to the digital signage 44 installed in the facility.

[0081] Fig. 10 is a block diagram showing an example of the functional configuration of a disaster information integration system 30' according to the second embodiment. In Fig. 10, components with the same reference numerals as those shown in Fig. 8 have the same functions, and therefore redundant explanations will be omitted here.

[0082] 10, the disaster information integration system 30′ individually includes a first processing unit 35A that generates disaster-related information for the administrator and transmits it to a first user terminal 41, a second processing unit 35B that generates disaster-related information for the patrol security guard who has jurisdiction over the first floor and transmits it to a second user terminal 42, a third processing unit 35C that generates disaster-related information for the patrol security guard who has jurisdiction over the second floor and transmits it to a third user terminal 43, and a fourth processing unit 35D that generates disaster-related information for digital signage 44 and transmits it to the digital signage 44. Each of the first to fourth processing units 35A to 35D includes a disaster-related information generation unit 33 and a disaster-related information transmission unit 34.

[0083] The disaster-related information generation unit 33 included in the fourth processing unit 35D generates disaster-related information for the digital signage 44. Furthermore, the disaster-related information transmission unit 34 included in the fourth processing unit 35D transmits the disaster-related information generated by the disaster-related information generation unit 33 to the digital signage 44 installed in the facility. Note that the above-described first to fourth variations of the first embodiment can also be applied to the disaster-related information displayed on this digital signage 44.

[0084] The disaster-related information generated by the fourth processing unit 35D is not intended for a specific individual, but is intended for an unspecified number of people in the vicinity of the installation location of the digital signage 44. Therefore, it is preferable that the disaster-related information generated by the fourth processing unit 35D be configured as information that is useful to an unspecified number of people. For example, it is possible to display, as disaster prevention information, a map image showing the route from the installation location of the digital signage 44 to the nearest evacuation shelter.

[0085] Furthermore, the disaster-related information displayed on the digital signage 44 can include an evacuation message encouraging evacuation. The evacuation message can be one of a first message that is displayed when the disaster-related information includes only earthquake-related information, a second message that is displayed when the disaster-related information includes only fire-related information, and a third message that is displayed when the disaster-related information includes both earthquake-related information and fire-related information and the evacuation guidance direction based on the earthquake-related information matches the evacuation guidance direction based on the fire-related information.

[0086] Here, the third message may be expressed in a way that more strongly urges evacuation than the first and second messages. For example, the first message may say, "Please remain calm and evacuate. There is no fire." The second message may say, "There is a fire. Please evacuate by following the evacuation instructions." It may also be possible to add a message such as, "There is no damage to the building, so please evacuate without worry." The third message may say, "An earthquake and fire have occurred. Please evacuate immediately."

[0087] <Modification 1 of the Second Embodiment> In the second embodiment described above, a single facility may be provided with a plurality of digital signage 44, and different disaster-related information may be displayed on each digital signage 44. For example, if the facility is a multi-story building, a digital signage 44 may be installed on each floor, and information for that floor may be displayed on each digital signage 44. Furthermore, in the case of a comprehensive facility including multiple buildings, a digital signage 44 may be installed in each building, and different disaster-related information may be displayed on each digital signage 44.

[0088] Furthermore, digital signage 44 may be installed on each floor of multiple buildings included in the comprehensive facility, and information about that floor may be displayed on the digital signage 44 on each floor. In this case, among the digital signage 44 installed in multiple buildings, the digital signage 44 installed on the same floor may display the same disaster-related information.

[0089] <Modification 2 of the Second Embodiment> In the second embodiment, the fourth processing unit 35D may transmit the generated disaster-related information to the first user terminal 41 in addition to the digital signage 44, so that the manager of the facility where the digital signage 44 is installed can check the content displayed on the digital signage 44. Furthermore, the disaster information integration system 30′ may be accessed from the first user terminal 41, and the content of the disaster-related information displayed on the digital signage 44 may be edited.

[0090] (Third embodiment) Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 11 is a diagram showing an example of the overall configuration of a disaster-related information provision system 1" according to the third embodiment. In FIG. 11, components having the same functions as those shown in FIG. 1 are given the same reference numerals. As shown in FIG. 11, the disaster-related information provision system 1" according to the third embodiment includes a disaster information integration system 30" instead of the disaster information integration system 30. The disaster information integration system 30" includes a disaster information integration server 30A" instead of the disaster information integration server 30A. In addition, it includes a communication device 21" instead of the communication device 21.

[0091] FIG. 12 is a block diagram showing an example of the functional configuration of a disaster information integration system 30" according to the third embodiment. In FIG. 12, components that are assigned the same reference numerals as those shown in FIG. 3 have the same functions, and therefore redundant explanations will be omitted here. As shown in FIG. 12, the disaster information integration system 30" includes a disaster-related information generation unit 33" instead of the disaster-related information generation unit 33, and further includes a monitoring information acquisition unit 36. The monitoring information acquisition unit 36 ​​is a functional configuration that the disaster information integration server 30A" includes.

[0092] When earthquake event information is acquired by the individual natural disaster event information acquisition unit 31 but fire event information is not acquired by the fire event information acquisition unit 32 (for example, when the fire event information acquisition unit 32 does not acquire fire event information within a predetermined time after the individual natural disaster event information acquisition unit 31 acquires the earthquake event information), the monitoring information acquisition unit 36 ​​receives an instruction from the disaster-related information generation unit 33'' and issues a request to the fire alarm equipment 20 to report the results of monitoring by the fire alarm equipment 20. Then, in response to the report request, the monitoring information acquisition unit 36 ​​acquires monitoring information indicating the results of monitoring from the fire alarm equipment 20.

[0093] When the communication device 21″ of the fire alarm system 20 receives a request to report the monitoring results from the monitoring information acquisition unit 36, the communication device 21″ of the fire alarm system 20 transmits the monitoring results to all the detectors 22 through the fire receiver 22. -1 ,twenty two -2 , . . . is checked. The result of the status check is sent back to the monitoring information acquisition unit 36 ​​as monitoring information. -1 ,twenty two -2 ,.... also has the function of detecting signs of a fire, the monitoring information that the communication device 21'' of the fire alarm system 20 returns in response to a report request from the monitoring information acquisition unit 36 ​​is one of the following.

[0094] (1) Information indicating that no fire has occurred. This is information indicating that no detector 22 -1 ,twenty two -2 This information is returned when no fire has been detected and no signs of a fire have been detected either in ,... (2) Information indicating the occurrence of signs of a fire. This is information from detector 22. -1 ,twenty two -2 ,..., is information that is returned when a sign of a fire is detected in any of the above. (3) Information indicating that a fire has occurred. This is detected by detector 22. -1 ,twenty two -2 ,..., is information that is returned when a fire is detected in any of the above.

[0095] When monitoring information is acquired by the monitoring information acquisition unit 36, the disaster-related information generation unit 33'' generates fire-related information based on the monitoring information, and also generates earthquake-related information based on the earthquake event information acquired by the individual natural disaster event information acquisition unit 31, thereby generating disaster-related information that includes both earthquake-related information and fire-related information.In this case, the fire-related information includes information indicating which of the above situations (1) to (3) is currently occurring.

[0096] Since earthquakes can cause damage to buildings, it cannot be concluded that no fire has occurred simply because the fire event information acquisition unit 32 has not acquired fire event information from the fire alarm system 20. In contrast, in the third embodiment, by performing the above-described processing, it is confirmed whether a fire has occurred and whether there are signs of a fire, and fire-related information is generated based on the confirmation results. This makes it possible to accurately grasp the situation regarding the presence or absence of a fire or its signs, and to provide the user with fire-related information that accurately reflects the actual situation. If the user of the user terminal 41, 42, 43 can confirm from the fire-related information provided in this manner that no fire has occurred, the user can concentrate on responding to issues other than the fire.

[0097] <Modification 1 of the third embodiment> Immediately after an earthquake causes damage to a building, an event that may be too small to be considered a fire at the time may occur, and this may escalate into a fire. If the fire alarm system 20 is to detect this "event that may escalate into a fire" during normal operation and issue fire event information, the criteria for determining whether a fire is occurring must be stricter. This is undesirable, as it would increase the number of false fire alarms (fires that are not actually fires). In contrast, when performing the processing of the third embodiment described above, the criteria for determining whether a fire is occurring by the fire alarm system 20 may not be set stricter during normal operation (before the monitoring information acquisition unit 36 ​​sends a request to report the monitoring results to the fire alarm system 20). Instead, when the communication device 21 receives a report request, the criteria for determining whether a fire is occurring or a fire may be set stricter, for example, by changing the threshold for determining whether a fire is occurring or a fire so that it is easier to detect the threshold, or by shortening the accumulated time from when the threshold is exceeded until the fire is determined to be a fire sign or a fire.

[0098] This will help prevent an increase in false fire alerts, and avoid a situation where fire-related information is not displayed until the signs of a fire have become significant enough or a fire has actually occurred, thereby preventing situations where a fire suddenly needs to be responded to while responding to an earthquake.

[0099] <Modification 2 of the Third Embodiment> The third embodiment may be applied in combination with the second embodiment. Here, disaster-related information generated based on the monitoring information of the fire alarm system 20 may be displayed on both the user terminals 41, 42, 43 and the digital signage 44. Alternatively, from the viewpoint of displaying only information of high importance on the digital signage 44, the disaster-related information generated based on the monitoring information of the fire alarm system 20 may be displayed only on the user terminal 41 of the administrator.

[0100] <Other variations> In the above first to third embodiments, examples have been described in which the predetermined area unit for providing natural disaster event information and fire event information is a facility unit, but the present invention is not limited to this. For example, a facility may be divided into multiple areas, and natural disaster event information and fire event information may be provided for each divided area. For example, each floor or each room within a building may be provided. In the case of fire event information, the monitoring area unit responsible for each fire terminal may be provided. When divided areas are used in this way, the facility information stored in the facility information storage unit 100 further includes information about the structure of the building. Furthermore, earthquake information for each divided area may be obtained, for example, by the method described in Japanese Patent No. 6661174.

[0101] Furthermore, in the above first to third embodiments, examples have been described in which disaster-related information including at least one of earthquake-related information and fire-related information is generated by the disaster information integration systems 30, 30', 30", but the present invention is not limited to this. For example, earthquake-related information may be generated by the natural disaster warning system 10 based on earthquake event information, and the earthquake-related information may be transmitted from the natural disaster warning system 10 to the disaster information integration systems 30, 30', 30".

[0102] Furthermore, in the above first to third embodiments, the disaster information integration systems 30, 30', 30" are configured to include the disaster information integration servers 30A, 30A" and the terminal information providing servers 30B, 30B', but are not limited to such a configuration. For example, the disaster information integration systems 30, 30', 30" may be configured with a single server.
