[0009] A disaster information notification system according to one embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0010] FIG. 1 is a block diagram of a disaster information notification system. FIG. 2 is a flowchart showing control related to initial setting in the notification device 1.

[0011] The disaster information notification system comprises a notification device 1 that is installed in each user's residence, checks for the presence or absence of disaster information, and notifies the user of the disaster information when disaster information occurs, a mobile terminal 3 that can wirelessly communicate with the notification device 1 via a router 2, and a disaster information supply device (hereinafter referred to as the supply device) 4 that the notification device 1 can connect to via the Internet.

[0012] The supply device 4 is a computer (e.g., a server) managed by a supplying entity such as a central government agency such as the Japan Meteorological Agency, or a local government such as a prefecture or a city, town, or village. The supply device 4 is configured to supply various types of hazard map information such as earthquake hazard maps, tsunami hazard maps, and flood hazard maps provided by local governments, evacuation information provided by local governments indicating the type of disaster that has occurred, whether or not an evacuation advisory has been issued, and designated emergency evacuation sites, and disaster prevention information provided by the Japan Meteorological Agency, including earthquake early warnings and tsunami warnings, alert information related to river flooding, and special weather warnings (in the present invention, the evacuation information provided by local governments and the disaster prevention information provided by the Japan Meteorological Agency are collectively referred to as disaster information).

[0013] The mobile terminal 3 is, for example, a smartphone carried by each user, and has the function of an input means used when setting up the notification device 1, and the function of an output means such as sounding an alarm in response to commands from the notification device 1.

[0014] The notification device 1 acquires necessary information from the supply device 4 via the Internet and executes predetermined notification operations based on the acquired information, and is equipped with a CPU 11 for controlling its own operations, a memory 12, a timer 13 for measuring time, a seismic intensity sensor 14 for detecting shaking caused by earthquakes, a speaker 15 for outputting warning sounds, etc., and a communication interface 16 for communicating with the outside world. The notification device 1 determines whether or not to notify disaster information related to earthquakes, tsunamis, and floods, and notifies the user of the disaster information as necessary.

[0015] Here, the control relating to the notification of disaster information in the notification device 1 will be described. The notification device 1 is installed in the residence where the user resides. First, the notification device 1 is initialized for disaster information notification (Fig. 2). This initialization is performed using the user's mobile terminal 3. After starting the setup operation by entering the notification device 1's identification ID, the user inputs the address of the residence where the notification device 1 is installed into the notification device 1 (S1). The user also inputs the location environment information (S2), resident information (S3), and building information (S4) described below into the notification device 1. After that, the user sets the output means for outputting the warning sound and warning message for disaster information notification (for example, setting only the speaker 15 as the output means, or setting both the speaker 15 and the mobile terminal 3 as the output means) (S5), completing the initial setup for disaster information notification. After the initialization is complete, the notification device 1 automatically connects to the supply device 4, acquires hazard map information corresponding to the input address, and updates the location environment information.

[0016] The location environment information is the environment surrounding the location of the dwelling unit, and includes first location environment information indicating whether there is a cliff next to the dwelling unit, and second location environment information indicating whether the maximum flood depth in the event of river flooding or the estimated tsunami flood depth is 5 m or more. The first location environment information is set in step S2 of the initial setting. The second location environment information is automatically set based on the hazard map information acquired by the notification device 1.

[0017] Resident information is information related to the residents residing in the dwelling unit, and includes information on whether any residents have weak legs, are bedridden, or are all healthy residents. The building information is information about the type of dwelling unit, including whether it is wooden, reinforced concrete with two floors or less, or reinforced concrete with three floors or more.

[0018] Then, in the notification device 1 whose initial settings have been made as described above, notification control including earthquake monitoring control (S11), tsunami information monitoring and notification control (S12), information acquisition control (S13), and evacuation information monitoring and notification control (S14) is repeatedly executed as shown in Figure 3.

[0019] First, to explain the earthquake monitoring control, the notification device 1 constantly detects the occurrence of earthquakes using the seismic intensity sensor 14. When an earthquake with a seismic intensity of lower 4 or higher is detected, a notification regarding the occurrence of an earthquake is output from the configured output means (for example, speaker 15 or mobile terminal 3). For this notification, the seismic intensity, building information, location environment information, and resident information are associated in advance in memory 12 with the message elements to be output (FIG. 6), and a composite warning message is created by combining the message elements based on the detected seismic intensity and each of the configured information, and the composite warning message is output from the configured output means (including speaker 15).

[0020] Specifically, if the detected seismic intensity is 6 or higher, the first seismic intensity message is selected, stating "A very strong earthquake has occurred." If the seismic intensity is 5+, the second seismic intensity message is selected, stating "A strong earthquake has occurred." If the seismic intensity is 5-low or lower, the third seismic intensity message is selected, stating "An earthquake has occurred." If the building is wooden and the seismic intensity is 5+ high or higher, the first earthquake building message is selected, stating "Your home may be destroyed." If the building is wooden and the seismic intensity is 5-low or lower, the second earthquake building message is selected, stating "Your home may not be able to withstand the earthquake." Furthermore, if a cliff is set next to the dwelling, the earthquake location message is selected, stating "The cliff may collapse." Regardless of the resident information set, the first earthquake resident message is selected, stating "Evacuate to a safe place." If the setting indicates that there is a person with weak legs, the second earthquake resident message is selected, stating "Help those with weak legs." If the setting indicates that there is a bedridden person, the third earthquake resident message is selected, stating "Evacuate together with the bedridden person."

[0021] For example, if the detected seismic intensity is 6 or higher, the building is reinforced concrete, some residents have weak legs, but the setting is such that there is no cliff next to the dwelling unit, the notification device 1 creates a composite warning message stating, "A very strong earthquake has occurred. Please evacuate to a safe place. Please help those with weak legs." This message is output from the output means. Also, if the detected seismic intensity is 5-lower, the building is wooden, the residents are healthy, but the setting is such that there is a cliff next to the dwelling unit, the notification device 1 creates a composite warning message stating, "An earthquake has occurred. There is a risk that the cliff behind you will collapse. Please evacuate to a safe place." This message is output from the output means. When the notification device 1 outputs a warning message from the speaker 15 during earthquake monitoring control, it also sounds a predetermined warning sound for a predetermined period of time before and after the message.

[0022] Furthermore, in the earthquake monitoring control, upon detecting the occurrence of an earthquake with a seismic intensity of lower 4 or greater, the earthquake flag used in the tsunami information monitoring and notification control, which will be described below, is turned ON, and timing of the time since the occurrence of the earthquake begins. The tsunami information monitoring and notification control will now be described with reference to FIG. 4. The notification device 1 determines whether the earthquake flag is ON (S21). If the earthquake flag is ON (YES in S21), the notification device 1 connects to the supply device 4 via the Internet and acquires disaster prevention information from the Japan Meteorological Agency (S22). The notification device 1 also checks the acquired disaster prevention information and determines whether a tsunami warning has been issued as disaster prevention information (S23). If a tsunami warning has been issued (YES in S23), the notification device 1 acquires evacuation information (mainly information related to evacuation destinations) from the local government, creates a composite warning message as described below, and outputs the composite warning message from the configured output means (including the speaker 15) (S24). On the other hand, if tsunami information has not been issued (NO in S23) and a composite warning message is being output, the output of the composite warning message is stopped (S25), and then a determination is made as to whether a predetermined tsunami monitoring time (e.g., 30 minutes) has elapsed since the occurrence of the earthquake (S26). If the time elapsed since the occurrence of the earthquake exceeds the tsunami monitoring time (YES in S26), the earthquake flag is turned OFF (S27). Note that if the earthquake flag is OFF in S21 (NO in S21), the tsunami information monitoring and notification control is terminated without acquiring disaster prevention information from the Japan Meteorological Agency, etc. Furthermore, if it is determined in S26 that the time elapsed since the occurrence of the earthquake has not exceeded the tsunami monitoring time (NO in S26), the earthquake flag is not turned OFF, and disaster prevention information is acquired from the Japan Meteorological Agency, etc., until the time elapsed since the occurrence of the earthquake exceeds the tsunami monitoring time.

[0023] The composite warning message created by the tsunami information monitoring and notification control is stored in memory 12 and includes information such as the fact that a tsunami warning has been issued, evacuation information obtained from local governments, building information, location environment information, and resident information, which are associated with the message elements to be output (see Figure 7). The message elements are combined based on the fact that a tsunami warning has been issued and the various pieces of information that have been set. Specifically, since a tsunami warning has been issued as disaster prevention information, a tsunami alert message stating "A tsunami warning has been issued" is selected. Furthermore, if the location environment information is set to "Second location environment information," a tsunami location message stating "This area may be flooded up to the second floor in the event of a tsunami" is selected. Furthermore, for all building information, regardless of type, a tsunami building message stating "To protect your life, please evacuate to the evacuation shelter, XX Elementary School" is selected. Furthermore, if the resident information indicates that someone has weak legs or is bedridden, a tsunami resident message stating "Please ask your neighbors for help when evacuating" is selected.

[0024] When a tsunami warning is issued following an earthquake, if the second location environment information is set and the area is set to include bedridden residents, a composite warning message stating, "A tsunami warning has been issued. This area may be flooded up to the second floor in the event of a tsunami. To save your life, please evacuate to the evacuation shelter, XX Elementary School. Please ask your neighbors for help when evacuating," is generated and output from the output means. Also, when a tsunami warning is issued following an earthquake, if the second location environment information is not set and the area is set to include only able-bodied residents, a composite warning message stating, "A tsunami warning has been issued. To save your life, please evacuate to the evacuation shelter, XX Elementary School," is generated and output from the output means. In addition, when the notification device 1 outputs a warning message from the speaker 15 during the tsunami information monitoring and notification control, a predetermined warning sound is sounded for a predetermined period of time before and after the message.

[0025] Further, the information acquisition control will be explained based on FIG. 5. The notification device 1 monitors the elapsed time since the last information acquisition (not the information acquisition related to the tsunami information monitoring and notification control, but the information acquisition related to the information acquisition control) (S31). If the elapsed time exceeds the unit time (the currently set unit time) (YES in S31), the notification device 1 connects to the supply device 4 via the Internet and acquires evacuation information from local governments and disaster prevention information from the Japan Meteorological Agency (S32). The notification device 1 also checks the acquired evacuation information and disaster prevention information and determines whether or not at least one of the evacuation information and disaster prevention information contains any warning information (specifically, whether various advisories, warnings, river flood alerts, evacuation advisories, etc. have been issued as evacuation information or disaster prevention information) (S33). If neither the evacuation information nor the disaster prevention information contains any warning information (NO in S33), the notification device 1 sets the unit time to a first unit time (e.g., 30 minutes) (S34), and terminates the information acquisition control. Therefore, the next acquisition of evacuation information, etc. will be after the first unit time has elapsed from the current acquisition. On the other hand, if there is content that requires a warning in either the evacuation information or the disaster prevention information (YES in S33), the unit time is set to a second unit time (for example, 5 minutes) (S35), and information acquisition control is terminated. Therefore, the next time evacuation information, etc. will be acquired after the second unit time has elapsed from the current time. Note that, if it is determined in S31 that the unit time has not elapsed since the previous information acquisition (NO in S31), the information acquisition control is naturally terminated without acquiring information or setting the unit time. Furthermore, after the unit time is changed to the second unit time, there is no longer any content that requires a warning in either the evacuation information or the disaster prevention information (NO in S33), and the unit time is returned to the first unit time.

[0026] In addition, regarding the evacuation information monitoring and notification control, the notification device 1 refers to the acquired disaster prevention information, and if the alert information related to river flooding (alert information issued in the designated river flood forecast by the Japan Meteorological Agency) includes flood caution information, flood alert information, flood danger information, or flood occurrence information, it outputs a notification related to river flooding from the set output means. Regarding this notification, the type of alert information, the content of the evacuation information acquired from the local government (such as the name of the river related to flooding and information related to evacuation destinations), building information, location environment information, and resident information, and the message elements to be output are previously associated in the memory 12 (FIG. 8), and the message elements are combined based on the type of alert information acquired and each set information to create a composite warning message, and the composite warning message is output from the set output means (including the speaker 15).

[0027] Specifically, if the acquired alert information is either a flood warning or a flood warning, the first flood warning message is selected, stating, "Due to heavy rain, the XX River is at risk of flooding." If the acquired alert information is a flood danger information, the second flood warning message is selected, stating, "Due to heavy rain, the XX River is at risk of flooding at any moment." If the acquired alert information is a flood occurrence information, the third flood warning message is selected, stating, "Due to heavy rain, the XX River has flooded." If the second location environment information is set as the location environment information, the flood location message is selected, stating, "This area is at risk of flooding up to the second floor in the event of a river flood." Furthermore, building information messages are only reflected when the second location environment information is set as the location environment information. If the building is a wooden or reinforced concrete building with two or fewer floors, the first flood building message is selected, stating, "To save your life, please evacuate to the evacuation shelter, XX Elementary School." If the building is a reinforced concrete building with three or more floors, the second flood building message is selected, stating, "To save your life, please evacuate vertically to a floor above the third floor." In addition, if the resident information is set to include people with weak legs or who are bedridden, a flood resident message saying "Ask your neighbors for help when evacuating" is selected.

[0028] For example, when a flood warning is issued, if the second location environment information is set and the building is set to be wooden and has bedridden residents, a composite warning message is generated that reads, "Due to heavy rain, the XX River is at risk of flooding. This area may be flooded up to the second floor if the river floods. To protect your life, please evacuate to the evacuation shelter, XX Elementary School. When evacuating, please ask your neighbors for help." This message is output from the output means. Also, when flood occurrence information is issued, if the second location environment information is set and the building is set to be reinforced concrete, three stories or higher, and only able-bodied residents, a composite warning message is generated that reads, "Due to heavy rain, the XX River has flooded. This area may be flooded up to the second floor if the river floods. To protect your life, please evacuate vertically to a floor above the third floor." This message is output from the output means. Furthermore, when flood risk information is issued, if the second location environment information is not set and only able-bodied residents are present, a composite warning message is generated that reads, "Due to heavy rain, there is danger that the XX River is about to flood." In addition, when the notification device 1 outputs a synthesized warning message from the speaker 15 in the evacuation information monitoring and notification control, it also sounds a predetermined warning sound for a predetermined time before and after the message.

[0029] In the disaster information notification system configured as described above, notification device 1 includes seismic intensity sensor 14 for detecting shaking caused by an earthquake, speaker 15 for outputting audio, CPU 11 for controlling its own operation, and memory 12. During initial setup, building information related to the user's residence, location environment information related to the location environment of the user's residence, and resident information related to the residents residing in the user's residence are set in memory 12. A hazard map corresponding to the user's residence is acquired from supply device 4 and stored in memory 12 as part of the location environment information. Memory 12 also stores multiple types of message elements associated with the seismic intensity, building information, location environment information, and resident information detected by seismic intensity sensor 14, as well as river flood alert information acquired from supply device 4. Upon detecting the occurrence of an earthquake, notification device 1 creates a composite warning message related to the occurrence of the earthquake based on the seismic intensity, building information, location environment information, and resident information, and outputs the composite warning message related to the occurrence of the earthquake from speaker 15. Furthermore, the notification device 1 acquires disaster information from the disaster information supply device upon detecting the occurrence of an earthquake. If the disaster information includes a tsunami warning, the notification device 1 creates a composite message related to the tsunami warning based on the tsunami warning, the evacuation information acquired from the local government, building information, location information, and resident information, and outputs the composite warning message related to the tsunami warning from the output means. Furthermore, the notification device 1 acquires disaster information from the disaster information supply device at predetermined time intervals. If the disaster information includes a river flood alert, the notification device 1 creates a composite warning message related to the river flood based on the alert, the evacuation information acquired from the local government, building information, location information, and resident information, and outputs the composite warning message related to the river flood from the output means. Therefore, a disaster information notification system can be realized that can provide more appropriate disaster information to users than before.

[0030] Furthermore, a first unit time and a second unit time shorter than the first unit time are set as unit times for acquiring disaster information from the supply device 4, and normally the notification device 1 acquires disaster information from the supply device 4 every first unit time, but if the disaster information includes warning information related to river flooding, the unit time is changed from the first unit time to the second unit time. Therefore, a disaster information notification system can be provided that can provide more appropriate notifications to users regarding disaster information.

[0031] The configuration of the disaster information notification system of the present invention is not limited to the aspects described in the above embodiments, and the configuration of the notification device, etc. can be appropriately modified as needed within the scope of the present invention.

[0032] For example, in the above embodiment, the building information set by the user is divided into three categories: wooden, reinforced concrete (2 stories or less), and reinforced concrete (3 stories or more), but the divisions may be more detailed, or may be divided into two categories: wooden and reinforced concrete, and the division method can be changed as appropriate. The same applies to location information and resident information; there is no problem with using categories not described in the embodiment, such as whether or not a dwelling is near a river as location information or whether or not there are elderly residents as resident information.

[0033] Furthermore, the notification device can be configured to acquire disaster information not only about earthquakes, tsunamis, and river flooding, but also about typhoons and heavy rains, and to output warning messages about these. Furthermore, in the above embodiment, the tsunami information monitoring and notification control is executed in association with earthquake monitoring using a seismic intensity sensor, but since a tsunami may occur due to an earthquake that occurs too far away for the seismic intensity sensor to detect, it is also possible to configure the tsunami information monitoring and notification control to be executed independently of monitoring using the seismic intensity sensor. In such an independent case, disaster information can be acquired from the disaster information supply device at predetermined unit time intervals. Furthermore, the specific contents of each warning message used to create the composite warning message can be changed as appropriate, as well as which category of information each message corresponds to. In addition, it is possible to provide a monitor on the notification device or use the monitor of a mobile terminal, so that when a warning message is output, it is displayed on the monitor to further draw attention to the message.
