DETAILED DESCRIPTION OF THE INVENTION

[0016] A disaster prevention system 1 according to an embodiment of the present invention will be described below. Note that the present invention is not limited to the following embodiment. Furthermore, the drawings referred to in the following description merely show a rough outline of the shape, size, and positional relationship to the extent that the contents of this disclosure can be understood. In other words, the present invention is not limited to only the shape, size, and positional relationship exemplified in each drawing.

[0017] The overall configuration of a disaster prevention system 1 according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic diagram showing the disaster prevention system 1 and various devices that notify disaster prevention related information.

[0018] The disaster prevention system 1 includes an electronic terminal 2 on which a program for executing disaster prevention notification output control, which will be described later, is installed, and a disaster prevention server 3 communicably connected via a communication network NW. The disaster prevention system 1 is a system for causing the electronic terminal 2 to output a disaster prevention notification to a user of the electronic terminal 2.

[0019] The disaster prevention notification is a notification for prompting the user to take action regarding evacuation. The disaster prevention notification may include a notification for prompting the user to take action for disaster prevention (hereinafter referred to as disaster prevention action) according to the situation before the disaster occurs and the situation of the disaster. The disaster prevention notification of this embodiment is a notification for prompting the user to start evacuation.

[0020] The communication network NW can be a wide area network (WAN) including a private network or the Internet. The former private network can be configured, for example, by a PON access system formed by an OLT (optical line terminal) and multiple ONUs (optical network units) connected to the OLT via optical lines, or by Layer 2 or Layer 3 switches. On the other hand, an example of a WAN is a network configured by an MPLS (Multiprotocol Label Switching) network.

[0021] The electronic terminal 2 is an electronic device connected to the communication network NW and having the function of outputting disaster prevention notifications. The electronic terminal 2 is communicably connected to a disaster prevention server 3, communication devices of public institutions (hereinafter referred to as public communication devices) 4, etc. via the communication network NW. The electronic terminal 2 may be, for example, a smartphone, a desktop, notebook, or tablet-type PC (Personal Computer), a television or radio connected to the communication network NW, or a wearable terminal such as a smartwatch. As the electronic terminal 2, a smartphone or a wearable terminal that users tend to carry for long periods of time is preferable, as it allows users to receive disaster prevention notifications more reliably.

[0022] The disaster prevention server 3 is communicably connected to the electronic terminal 2, the public communication device 4, the detection device group 5, and the disaster prevention chat server 6 via the communication network NW. The disaster prevention server 3 acquires disaster prevention-related information from the public communication device 4, the detection device group 5, and the disaster prevention chat server 6, and transmits a control signal to the electronic terminal 2 to output a disaster prevention notification based on the acquired disaster prevention-related information. The disaster prevention-related information is information related to disaster prevention regarding the natural environment of the target area. Examples of the disaster prevention-related information include information indicating the disaster situation in the target area and the occurrence of events that are likely to lead to disasters, such as heavy rain. The target area is set in advance by the user's selection. The target area may be a range close to a point selected by the user. For example, the target area may be within a range of several hundred meters to several kilometers from the user's residence. Alternatively, the target area may be a range close to a point selected by the user and with a similar surrounding environment. Examples of the surrounding environment include mountainous areas that may be damaged in the event of a landslide or riverside areas that may be damaged in the event of a river flood.

[0023] The public communication devices 4 are installed in various public institutions and are devices that transmit disaster prevention related information. Examples of public institutions include administrative agencies such as the Japan Meteorological Agency, local governments, etc. Examples of disaster prevention related information notified by the public communication devices 4 include weather information, advisories and warnings, evacuation instructions, etc. Weather information includes, for example, rainfall, etc. Examples of advisories and warnings include heavy rain warnings, special heavy rain warnings, flood warnings, storm surge warnings, storm surge warnings, special storm surge warnings, flood warning information, flood alert information, flood risk information, flood occurrence information, landslide warning information, etc.

[0024] The detection equipment group 5 includes a soil moisture sensor 51, a water level sensor 52, a river radar 53, and a river camera 54.

[0025] The soil moisture sensor 51 is a sensor that detects the amount of moisture contained in the soil as disaster prevention related information. The soil moisture sensor 51 is placed in the soil of a mountain, etc. By understanding the amount of moisture in the soil using the soil moisture sensor 51 placed in the soil of the mountain, it is possible to predict the possibility of a landslide disaster occurring.

[0026] The water level sensor 52 is a sensor that detects the water level of a river, pond, rice field, etc. as disaster prevention related information. Examples of the water level sensor 52 include capacitance type, float type, ultrasonic type, and pressure type.

[0027] The river radar 53 is a radar that detects the flow velocity of a river as disaster prevention related information. For example, the river radar 53 irradiates a water surface with radio waves and detects the flow velocity of the river based on the irradiated waves and the reflected waves reflected from the water surface.

[0028] The river camera 54 is a camera that detects whether or not a river is flooding as disaster prevention related information. The river camera 54 detects whether or not a river is flooding from, for example, a captured image of the river, and if a river flood occurs, notifies the disaster prevention server 3 via the communication network NW.

[0029] The disaster prevention chat server 6 is a server of a chat system in which multiple users registered in the disaster prevention system 1 send and receive messages in real time via the communication network NW. In the disaster prevention chat server 6, messages related to disaster prevention sent by other users of the disaster prevention system 1 exist as disaster prevention related information. Examples of disaster prevention related information in the disaster prevention chat server 6 include messages related to the actions and surrounding conditions of other users, such as a message informing other users that they have started evacuation (hereinafter referred to as an evacuation start message) and a message informing other users that a river flowing near the other users has flooded. In this specification, information related to a user's evacuation situation, including an evacuation start message, is referred to as other users' evacuation information.

[0030] When disaster warnings issued by public institutions and other organizations cover a wide area, there is a risk of discrepancies between the content of the warning and the actual local conditions in some areas. Weather conditions are particularly variable in mountainous and intermountainous areas. For example, even if a flood or landslide warning is issued for a specific area, some areas may not experience much rain. Conversely, evacuation orders may not be issued in some areas despite heavy rain and the imminent risk of flooding or landslides. If a disaster warning is suddenly issued that does not necessarily reflect the actual conditions of the user's location, residents may not take the warning seriously, potentially delaying evacuation. In contrast, the disaster prevention system 1 according to this embodiment can enhance users' sense of ownership and encourage voluntary evacuation.

[0031] Next, the functional configuration of the electronic terminal 2 will be described with reference to Fig. 2 and Fig. 3. Fig. 2 is a block diagram showing the configuration of hardware and functional blocks of the electronic terminal 2. Fig. 3 is a block diagram showing the hardware configuration of the computer 27 of the electronic terminal 2.

[0032] As shown in FIG. 5, the electronic terminal 2 includes a processing unit 20, an input unit 21, an output unit 22, a storage unit 23, and a communication I / F unit 24.

[0033] The processing unit 20 is configured by, for example, a processor 271, and is the central part of the computer 27 that performs processing such as calculations and controls required for the operation of the electronic terminal 2, and performs various calculations and processing.

[0034] As shown in FIG. 3 , the computer 27 of the electronic terminal 2 includes a processor 271, a ROM 272 and a RAM 273 as main storage devices, a bus 274, and the like. The processor 271 may be a central processing unit (CPU), a microprocessing unit (MPU), a system on a chip (SoC), a digital signal processor (DSP), a graphics processing unit (GPU), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA). Alternatively, the processor 271 may be a combination of these. The processor 271 may also be a combination of these with a hardware accelerator or the like. The processor 271 controls each unit to realize various functions of the electronic terminal 2 based on programs such as firmware, system software, and application software stored in the ROM 272, the RAM 273, or an auxiliary storage device that is part of the storage unit 23. Note that some or all of the programs may be incorporated into the processor's circuitry. The configuration of the processing unit 20's disaster prevention notification output control function will be described later.

[0035] The input unit 21 is a user interface electrically connected to the processing unit 20. The input unit 21 is composed of buttons, a display 25, a camera, etc. The display 26 is composed of, for example, a liquid crystal display (LCD) or an organic electro-luminescent (EL) display, and a touch panel that detects the position touched by the user is provided on the image display surface of the display 25. The user can input information by touching the image display surface of the display 25.

[0036] The output unit 22 is a user interface that is electrically connected to the processing unit 20. The output unit 22 is configured with a display 25, a speaker (not shown) that amplifies sound, etc. The output unit 22 is controlled by the processing unit 20 and outputs a disaster prevention notification to the user.

[0037] The storage unit 23 is a storage area for storing various programs and various data for causing the hardware group to function as the electronic terminal 2, and can be configured with a ROM, RAM, flash memory, a solid-state drive (SSD), a hard disk drive (HDD), or the like. Specifically, the storage unit 23 stores programs for causing the processing unit 20 to execute each function of this embodiment, user information about the user of the electronic terminal 2, acquired disaster prevention-related information, setting information (described later), judgment criteria conditions, and the like. Examples of user information include a target area set by the user himself / herself, including the user's place of residence, and user identification information such as the ID of the electronic terminal 2 itself.

[0038] The communication I / F unit 24 is an interface for the electronic terminal 2 to communicate via the communication network NW. The electronic terminal 2 is connected to the disaster prevention server 3, the public communication equipment 4, etc. via the communication I / F unit 24 so as to be able to communicate with them.

[0039] As shown in FIG. 2, the processing unit 20 includes a receiving unit 201, a reference condition setting unit 202, a reference condition transmitting unit 203, an output processing unit 204, a disaster prevention related information acquiring unit 205, and a revision proposal presenting unit 206.

[0040] The reception unit 201 executes a process of receiving input of setting information to the input unit 21 by user operation. The setting information is information for setting judgment criteria conditions for outputting a disaster prevention notification via the output unit 22 of the electronic terminal 2. The setting information is information selected by the user. The judgment criteria conditions are criteria for determining whether or not to output a disaster prevention notification from the electronic terminal 2. That is, in the disaster prevention system 1, the judgment criteria conditions, which are the output conditions for a disaster prevention notification, are set in advance by the user's own selection and can be changed by the user as appropriate.

[0041] The reference condition setting unit 202 executes a process of setting the determination reference conditions based on the setting information.

[0042] The judgment criteria conditions will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of a table of judgment criteria conditions set by a certain user.

[0043] The table shown in FIG. 4 (hereinafter referred to as the judgment criterion condition table) has five judgment criterion conditions, from Alert 1 to Alert 5, set for outputting a disaster prevention notification. Alert 1 is a condition for outputting a disaster prevention notification when the rainfall in the target area is 60 mm / h or more. Alert 2 is a condition for outputting a disaster prevention notification when the water level of a river in the target area is 5 m or more and the river flow speed is 2.5 m / s or more. Alert 3 is a condition for outputting a disaster prevention notification when a river in the target area overflows. Alert 4 is a condition for outputting a disaster prevention notification when the moisture content of the soil in which the soil moisture sensor 51 is located in the target area is 80% or more. Alert 5 is a condition for outputting a disaster prevention notification when the water level of a river in the target area is 5 m or more, the rainfall is 40 mm / h, and two or more evacuation start messages are sent by other users in the target area via the chat system. In the judgment criterion condition table, the user can change the items, thresholds, units, etc. of the judgment criterion condition table displayed on the display 25 via the input unit 21, add new rows, or delete rows. In this case, the setting information refers to the contents of the items, thresholds, units, etc. of the judgment criterion condition table. The criterion condition setting unit 202 sets the judgment criterion conditions by reading and reflecting the setting information input by the user.

[0044] Another example of the setting information will be described with reference to Fig. 5. Fig. 5 is a diagram showing an example of an evacuation plan table 7 in which information related to the user's evacuation plan is displayed. The setting information may be, for example, information related to the user's evacuation plan, such as the evacuation plan table 7 shown in Fig. 5.

[0045] The evacuation plan table 7 is a data sheet containing information about evacuation plans, and is a plan that chronologically organizes disaster prevention actions that the user will take depending on the situation. As shown in Fig. 5, the evacuation plan table 7 includes a plurality of display items 71 that show disaster prevention-related information, selection items 72 corresponding to each of the plurality of display items 71, and input items 73 for the user to input conditions for starting evacuation.

[0046] 5, the multiple display items 71 are arranged in order of the disaster alert level corresponding to the displayed disaster prevention-related information. The selection items 72 are items for selecting disaster prevention actions corresponding to each of the display items 71. The selection items 72 are provided with tabs 74 for selecting disaster prevention actions from multiple predetermined actions.

[0047] The input item 73 is an item for inputting the conditions for starting evacuation by the user. In the example of the evacuation plan table 7 shown in Fig. 5, the condition input is that when the water level in the rice paddy in front of the user's house reaches a predetermined amount, a disaster prevention notification urging the user to start evacuation is output.

[0048] The evacuation plan table 7 may be configured on paper so that the contents of the display items 71, selection items 72 including tabs 74, and input items 73 can be electronically readable, or may be an electronic document such as a spreadsheet. When the evacuation plan table 7 is configured on paper, the reception unit 201 may receive the setting information by reading the information shown in the display items 71, selection items 72, and input items 73 of the evacuation plan table 7 as digital information using a camera serving as the input unit 21. When the evacuation plan table 7 is an electronic document, the reception unit 201 may receive an electronic document generated by a user operation via the buttons or display 25 of the electronic terminal 2 as the setting information.

[0049] The reference condition setting unit 202 sets the judgment reference condition based on the information shown in the evacuation plan table 7. For example, in the example shown in Fig. 5, the reference condition setting unit 202 sets the judgment reference condition that a disaster prevention notice urging people to start evacuation will be output when landslide warning information or flood risk information for the target area is acquired, based on the information in the display item 71 for alert level 4 and the selection item 72 corresponding to the display item 71. The reference condition setting unit 202 also sets the judgment reference condition that a disaster prevention notice urging people to start evacuation will be output when the water level of a rice paddy at a predetermined point in the target area exceeds a predetermined threshold, based on the information in the input item 73.

[0050] Furthermore, the setting information may be setting information created by the user based on the proposed revision when the revision proposal presenting unit 206, which will be described later, acquires a proposed revision to the judgment criterion conditions transmitted from the disaster prevention server 3 and presents the proposed revision to the user. The setting information created by the user based on the proposed revision may be the proposed revision itself, or information in which the user has further modified the proposed revision. Details regarding the proposed revision to the judgment criterion conditions will be described later.

[0051] The criterion condition transmission unit 203 executes a process of transmitting the judgment criterion conditions set by the criterion condition setting unit 202 to the disaster prevention server 3 via the communication unit I / F 24. In this embodiment, the criterion condition transmission unit 203 links the user information of the electronic terminal 2 to the judgment criterion conditions and transmits the linked information to the disaster prevention server 3.

[0052] The output processing unit 204 executes a process of controlling the output unit 22 to output a disaster prevention notification based on a control signal transmitted from the disaster prevention server 3. The output processing unit 204 may, for example, display a message urging the user to start evacuation as a disaster prevention notification on the display 25, or may output an alarm urging the user to start evacuation as a disaster prevention notification via a speaker.

[0053] The disaster prevention related information acquisition unit 205 executes a process of acquiring disaster prevention related information such as weather information, warning alerts, and evacuation instructions from the public communication equipment 4 via the communication I / F unit 24 .

[0054] The revision proposal presentation unit 206 executes a process of acquiring a revision proposal for the judgment criterion conditions from the disaster prevention server 3 via the communication I / F unit 24 and presenting the acquired revision proposal to the user. For example, the revision proposal presentation unit 206 presents the revision proposal to the user by displaying the revision proposal for the judgment criterion conditions acquired from the disaster prevention server 3 on the output unit 22.

[0055] Next, the functional configuration of the disaster prevention server 3 will be described with reference to Figs. 6 and 7. Fig. 6 is a block diagram showing the configuration of the hardware and functional blocks of the disaster prevention server 3. Fig. 7 is a block diagram showing the hardware configuration of the computer 37 of the disaster prevention server 3.

[0056] As shown in FIG. 6, the disaster prevention server 3 includes a processing unit 30, a storage unit 33, and a communication I / F unit .

[0057] The processing unit 30 is configured by, for example, a processor, and is the central part of a computer that performs processing such as calculations and controls required for the operation of the disaster prevention server 3, and performs various calculations and processing.

[0058] As shown in FIG. 7 , the computer 37 of the disaster prevention server 3 includes a processor 371, a ROM 372 and RAM 373 as main storage devices, a bus 374, etc. The processor 371 may be a central processing unit (CPU), a microprocessing unit (MPU), a system on a chip (SoC), a digital signal processor (DSP), a graphics processing unit (GPU), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA). Alternatively, the processor may be a combination of these. The processor 371 may also be a combination of these with a hardware accelerator. The processor 371 controls each unit to realize various functions of the disaster prevention server 3 based on programs such as firmware, system software, and application software stored in the ROM 372, RAM 373, or an auxiliary storage device that is part of the storage unit 33. Note that some or all of the programs may be incorporated into the circuitry of the processor 371. The configuration of the processing unit 30 related to the disaster prevention notification control function will be described later.

[0059] The storage unit 33 is a storage area for various programs and various data for causing the hardware group to function as the disaster prevention server 3, and can be configured with a ROM, RAM, flash memory, a solid-state drive (SSD), a hard disk drive (HDD), etc. Specifically, the storage unit 33 stores programs for causing the processing unit 30 to execute each function of this embodiment, user information of the electronic terminal 2, acquired disaster prevention-related information, judgment criteria conditions transmitted from the electronic terminal 2, and reference values used to judge the validity of the judgment criteria conditions, which will be described later, etc.

[0060] The communication I / F unit 34 is an interface for the disaster prevention server 3 to communicate via the communication network NW. The disaster prevention server 3 is connected to the electronic terminal 2, the public communication device 4, the detection device group 5, the disaster prevention chat server 6, etc. via the communication I / F unit 34 so as to be able to communicate with them.

[0061] As shown in FIG. 6, the processing unit 30 includes a reference condition acquisition unit 301 , a disaster prevention related information acquisition unit 302 , a determination unit 303 , a transmission processing unit 304 , and a revision proposal creation unit 305 .

[0062] The criterion condition acquisition unit 301 executes a process of acquiring, via the communication I / F, the criterion conditions transmitted from the electronic terminal 2 via the communication network NW. In this embodiment, the criterion condition acquisition unit 301 acquires the criterion conditions as well as user information linked to the criterion conditions. By acquiring the user information of the electronic terminal 2, the processing unit 30 can identify the target area for each parameter of the criterion conditions.

[0063] The disaster prevention related information acquisition unit 302 executes a process of acquiring disaster prevention related information for the target area indicated by the user information from the public communication device 4, the detected device group 5, and the disaster prevention chat server 6 via the communication network NW.

[0064] The determination unit 303 executes a process of determining whether or not the determination criterion condition is satisfied based on a comparison result between the determination criterion condition acquired by the reference condition acquisition unit 301 and the disaster prevention related information acquired by the disaster prevention related information acquisition unit 302. For example, when the determination criterion condition is the information shown in the determination criterion condition table in Fig. 4, if the disaster prevention related information acquisition unit 302 acquires disaster prevention related information indicating that the amount of rainfall in the target area is 60 mm / h or more, the determination unit 303 determines that the determination criterion condition is satisfied because the disaster prevention related information is equal to or greater than the threshold set in the alert 1.

[0065] The revision proposal creation unit 305 determines whether the judgment criteria conditions acquired by the criteria condition acquisition unit 301 are appropriate as conditions for outputting a disaster prevention notification, and if it determines that they are not appropriate, executes a process to create a revision proposal for the judgment criteria conditions.

[0066] The revision proposal creating unit 305 may, for example, compare a validity determination reference value with the judgment reference condition to determine whether the judgment reference condition is valid. The validity determination reference value may be, for example, a reference value for issuing advisories and warnings in the user's target area set by a public institution such as the Japan Meteorological Agency (hereinafter referred to as the public institution's reference value), or a reference value previously set in the disaster prevention system 1. For example, the revision proposal creating unit 305 may determine that a value within a predetermined numerical range from the public institution's reference value is valid, and that a value outside the predetermined numerical range is invalid. The revision proposal creating unit 305 may then create the public institution's reference value as a revision proposal for the judgment reference condition. For example, if the public institution's reference value for issuing an evacuation warning to residents in the target area is a rainfall of 60 m / h or more, but the judgment reference condition for outputting a disaster prevention notification encouraging evacuation is set to a rainfall of 80 m / h or more, the judgment reference condition may be determined to be invalid. If the revision proposal creating unit 305 determines that the criterion condition is inappropriate, it may create a condition that the rainfall in the target area is 60 m / h or more as a revision proposal for the criterion condition. Furthermore, for example, if the reference value for determining appropriateness is five or more evacuation start messages from other users in the target area and the number of evacuation start messages is set to ten or more as the criterion condition, the revision proposal creating unit 305 may determine that the criterion condition is inappropriate. If the revision proposal creating unit 305 determines that the criterion condition is inappropriate, it may create a condition that the number of evacuation start messages from other users in the target area is five or more as a revision proposal for the criterion condition.

[0067] When the determination unit 303 determines that the determination criteria condition is satisfied, the transmission processing unit 304 executes a process of transmitting a control signal (hereinafter, output command signal) for causing the electronic terminal 2 to output a disaster prevention notification. Upon receiving the output command signal, the electronic terminal 2 controls the output unit 22 to output the disaster prevention notification.

[0068] Furthermore, when the amendment proposal creating unit 305 creates an amendment proposal for the criterion conditions, the transmission processing unit 304 executes a process of transmitting the amendment proposal to the electronic terminal 2. Upon receiving the amendment proposal, the electronic terminal 2 presents the amendment proposal to the user via the output unit 22.

[0069] Next, an example of the flow of disaster prevention notification output processing in the disaster prevention system 1 will be described with reference to FIGS.

[0070] First, the flow of communication between the electronic terminal 2 and the disaster prevention server 3 until the disaster prevention processing is output will be described with reference to Fig. 8. Fig. 8 is a sequence diagram showing an example of communication between the electronic terminal 2 and the disaster prevention server 3 performed in the disaster prevention notification processing.

[0071] As shown in FIG. 6, in step S1, the electronic terminal 2 receives setting information input to the input unit 21 by the user.

[0072] In step S2, the electronic terminal 2 sets the determination criteria conditions based on the setting information received in step S1.

[0073] In step S3, the electronic terminal 2 transmits to the disaster prevention server 3 the determination criteria conditions set in step S2 and the user information of the electronic terminal 2.

[0074] In step S4, the disaster prevention server 3 acquires disaster prevention related information for the target area indicated by the user information transmitted in step S3.

[0075] In step S5, the disaster prevention server 3 compares the determination criteria conditions acquired in step S3 with the disaster prevention related information acquired in step S4, and determines whether or not the determination criteria conditions are met.

[0076] In step S6, the disaster prevention server 3 transmits an output command signal to the electronic terminal 2 if it is determined in step S5 that the determination criteria condition is met.

[0077] In step S7, the electronic terminal 2 receives the output command signal transmitted in step 6 and outputs a disaster prevention notification.

[0078] Next, an example of disaster prevention notification output control executed by the processing unit 20 of the electronic terminal 2 will be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of disaster prevention notification output control executed by the processing unit 20 of the electronic terminal 2.

[0079] 9, in step S11, the receiving unit 201 of the processing unit 20 receives setting information input by a user operation to the input unit 21. The setting information may be, for example, an evacuation plan of the user.

[0080] In step S12, the reference condition setting unit 202 sets the judgment reference conditions based on the setting information received in step S11. For example, the reference condition setting unit 202 may read the information shown in the user's evacuation plan acquired in step S11 using a camera, a scanner, or the like, extract information related to the start of evacuation by the user from the read information, and set the judgment reference conditions based on the extracted information.

[0081] In step S13, the criterion condition transmission unit 203 associates the determination criterion condition set in step S12 with the user information of the electronic terminal 2, and transmits the association to the disaster prevention server 3 via the communication network NW.

[0082] In step S14, the revision proposal presentation unit 206 determines whether or not the revision proposal for the judgment criterion conditions transmitted in step S13 from the disaster prevention server 3 has been received. If the revision proposal presentation unit 206 determines that the revision proposal for the judgment criterion conditions has been received (YES in step S14), the process proceeds to step S15, where the revision proposal is presented to the user by displaying the revision proposal on the output unit 22, and the process returns to step S11. On the other hand, if the revision proposal presentation unit 206 determines that the revision proposal for the judgment criterion conditions has not been received (NO in step S14), the process proceeds to step S16.

[0083] In step S16, the output processing unit 204 determines whether or not an output command signal has been received from the disaster prevention server 3 via the communication I / F unit 24. If the output processing unit 204 determines that an output command signal has not been received (NO in step S16), the process proceeds to step S17, and repeats the process of step S16 after a predetermined time has elapsed. On the other hand, if the output processing unit 204 determines that an output command signal has been received (YES in step S16), the process proceeds to step S18.

[0084] In step S18, the output processing unit 204 controls the output unit 22 to output the disaster prevention notification. For example, the output processing unit 204 may output an alarm urging people to start evacuation as the disaster prevention notification via a speaker. Thereafter, the processing unit 20 ends the disaster prevention notification output control.

[0085] Next, an example of disaster prevention notification output control executed by the processing unit 30 of the disaster prevention server 3 will be described with reference to Fig. 10. Fig. 10 is a flowchart showing an example of disaster prevention notification output control executed by the processing unit 30 of the disaster prevention server 3.

[0086] As shown in FIG. 10, in step S21, the criterion condition acquisition unit 301 acquires the determination criterion conditions and user information transmitted from the electronic terminal 2 in step S13 via the communication network NW.

[0087] In step S22, the revision proposal creating unit 305 determines whether the criterion conditions acquired in step S21 are appropriate as conditions for outputting a disaster prevention notification. For example, the revision proposal creating unit 305 extracts from the storage unit 33 a criterion value for determining appropriateness of the target area indicated by the user information acquired in step S21, and compares the extracted criterion value for determining appropriateness with the criterion conditions acquired in step S21 to determine whether the criterion conditions are appropriate. If the revision proposal creating unit 305 determines that the criterion conditions are not appropriate (NO in step S22), the process proceeds to step S23, where it creates a revision proposal for the criterion conditions. In step S24, the transmission processing unit 304 transmits the revision proposal created in step S23 to the electronic terminal 2 via the communication network NW, and returns the process to step S21 after a predetermined time has elapsed. On the other hand, if the revision proposal creating unit 305 determines that the criterion conditions are appropriate (YES in step S22), the process proceeds to step S26.

[0088] In step S26, the disaster prevention related information acquisition unit 302 acquires disaster prevention related information for the target area indicated by the user information acquired in step S21 from the public communication device 4, the detection device group 5, and the disaster prevention chat server 6 via the communication network NW.

[0089] In step S27, the determination unit 303 compares the latest determination criterion condition acquired in step S21 with the latest disaster prevention-related information acquired in step S26, and determines whether the determination criterion condition is satisfied in the target area based on the comparison result. If the determination unit 303 determines that the determination criterion condition is not satisfied (NO in step S27), it proceeds to step S28, and returns to step S26 after a predetermined time has elapsed. On the other hand, if the determination unit 303 determines that the determination criterion condition is satisfied (YES in step S27), it proceeds to step S29.

[0090] In step S29, the transmission processing unit 304 transmits an output command signal for the disaster prevention notification via the communication network NW to the electronic terminal 2. After that, the processing unit 30 ends the disaster prevention notification output control.

[0091] According to the embodiment described above, the following effects are achieved.

[0092] The program of this embodiment is a program for causing the computer 27 to execute a processing step of comparing the judgment criteria conditions for outputting a notification encouraging evacuation-related actions via the output unit 22 of the electronic terminal 2 with disaster prevention-related information of the target area, and if the judgment criteria conditions are met, outputting a notification encouraging evacuation-related actions via the output unit 22 of the electronic terminal 2, where the judgment criteria conditions and the target area are set in advance by the user's own selection.

[0093] This allows disaster prevention alerts to be output based on the criteria determined based on the user's own selection and the disaster prevention-related information for the area selected by the user, so disaster prevention notifications can be issued in a way that allows the user to take a more proactive stance and feel a sense of ownership. This makes disaster prevention actions more personal, reducing the possibility that the user will miss an opportunity to evacuate appropriately in the event of a disaster.

[0094] In the program according to this embodiment, the disaster prevention notification is a notification for urging the user to start evacuation.

[0095] This makes it possible to more reliably encourage users to evacuate.

[0096] In the program according to this embodiment, the determination criteria conditions are generated from setting information, which is information relating to the user's evacuation plan.

[0097] This allows the determination criteria to be automatically determined based on information about the evacuation plan created by the user, making it easier to set the determination criteria.

[0098] In addition, the program according to this embodiment determines whether the selection of criteria conditions made by the user is appropriate for a disaster prevention notification, and if it is determined to be inappropriate, presents the user with suggested revisions.

[0099] This allows the user to be presented with a suggested correction if the criterion condition selected by the user is not appropriate, thereby assisting the user in selecting an appropriate criterion condition.

[0100] In addition, in the program of this embodiment, the information regarding the evacuation plan is composed of display items 71 that show multiple pieces of disaster prevention related information, each of which is associated with a disaster alert level, and selection items 72 that select disaster prevention actions that correspond to each of the display items 71 from multiple predetermined actions.

[0101] This allows users to easily create appropriate evacuation plans by selecting actions appropriate to each piece of disaster prevention-related information associated with the disaster alert level from a plurality of predetermined actions. Since the criteria for judgment are automatically determined based on the information about the evacuation plan, users can actively and easily set the criteria for judgment.

[0102] In the program according to this embodiment, disaster prevention related information includes weather information, advisories and warnings, soil moisture content, and other user evacuation information relating to the evacuation status of other users.

[0103] This allows disaster prevention notifications to be output at a time that takes into account various disaster prevention-related information for the area selected by the user, thereby supporting more reliable evacuation of users even if the time between the issuance of an alert or the occurrence of a disaster is relatively short.

[0104] The disaster prevention system 1 according to the present embodiment includes an electronic terminal 2 that outputs a disaster prevention notification to a user via an output unit 22, and a disaster prevention server 3 that can communicate with the electronic terminal 2, and executes the above program. The electronic terminal 2 includes a reception unit 201 that receives setting information selected by the user, which is information for setting a determination criterion condition for whether or not to output a disaster prevention notification from the electronic terminal 2, a criterion condition setting unit 202 that sets the determination criterion condition based on the setting information, a criterion condition transmission unit 203 that transmits the determination criterion condition to the disaster prevention server 3, and a disaster prevention system 1 that outputs a disaster prevention notification via the output unit 22 based on a control signal received from the disaster prevention server 3. The disaster prevention server 3 has an output processing unit 204 that processes the information to output the disaster prevention notification, and the disaster prevention server 3 has a standard condition acquisition unit 301 that acquires the judgment standard conditions from the electronic terminal 2, a disaster prevention related information acquisition unit 302 that acquires disaster prevention related information for a target area selected by the user, a judgment unit 303 that judges whether the judgment standard conditions are satisfied or not based on a comparison result between the judgment standard conditions acquired by the standard condition acquisition unit 301 and the disaster prevention related information acquired by the disaster prevention related information acquisition unit 302, and a transmission processing unit 304 that transmits an output command signal to the electronic terminal 2 to output a disaster prevention notification when the judgment unit 303 judges that the judgment standard conditions are satisfied.

[0105] In addition, the notification method of this embodiment is a notification method that has a processing step of comparing the judgment criteria conditions for outputting a notification to encourage evacuation behavior via the output unit 22 of the electronic terminal 2 with disaster prevention related information of the target area, and if the judgment criteria conditions are met, processing is performed to output the notification to encourage evacuation behavior via the output unit 22 of the electronic terminal 2, and the judgment criteria conditions and the target area are set in advance by the user's own selection.

[0106] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate.

[0107] For example, the detection device group 5 may include a mountain camera that acquires images of mountain slopes and, when it detects a sign of a landslide or the like as disaster prevention related information, notifies the disaster prevention server 3 via the communication network NW. The electronic terminal 2 may then set a determination criterion condition that includes, as a parameter, the disaster prevention related information detected by the mountain camera.

[0108] For example, the electronic terminal 2 may set a determination criterion condition that includes as a parameter the amount of rainfall detected in the target area by the rain gauge of another user of the disaster prevention system 1. Then, the disaster prevention server 3 may acquire the amount of rainfall detected by the rain gauge of another user transmitted from the disaster prevention chat server 6 via the communication network NW.

[0109] Furthermore, for example, the processing unit 20 of the electronic terminal 2 may not include the revision proposal presenting unit 206, and the processing unit 30 of the disaster prevention server 3 may not include the revision proposal creating unit 305. In other words, the disaster prevention system 1 may be configured to determine whether the selection of the determination criteria condition made by the user is appropriate for disaster prevention notification, and if it is determined to be inappropriate, not to perform processing to present a revision proposal to the user.
