DETAILED DESCRIPTION OF THE INVENTION

[0013] 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.

[0014] 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.

[0015] The disaster prevention system 1 includes an electronic terminal 2 on which a program for executing a disaster prevention display process (display control step) 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 displaying disaster prevention-related information on a user as visual information on a display unit 22 configured by a display 25 of the electronic terminal 2, etc. Details of the display unit 22 will be described later.

[0016] Disaster prevention-related information is information related to disaster prevention regarding the natural environment of a target area. Examples of disaster prevention-related information include information indicating the disaster situation in the target area and the occurrence status of events that have a high possibility of leading to a disaster, such as heavy rain. Disaster prevention-related information also includes notifications encouraging the user to take disaster prevention actions (hereinafter referred to as disaster prevention actions) according to the situation before the disaster occurs and the disaster situation. The target area is set in advance by the user's selection. The target area may be an area close to a point selected by the user. For example, it may be within a range of several hundred meters to several kilometers from the user's place of residence. Alternatively, it may be an area 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.

[0017] 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 switches or Layer 3 switches. On the other hand, the WAN can be configured, for example, by an MPLS (Multiprotocol Label Switching) network.

[0018] The electronic terminal 2 is an electronic device connected to a communication network NW and has the function of displaying disaster prevention related information. 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 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 related information more reliably.

[0019] The disaster prevention server 3 is communicably connected to the electronic terminal 2, the public communication device 4, the detection device group 5, the disaster prevention chat server 6, and the data sharing server 7 via the communication network NW. The disaster prevention server 3 executes a process of acquiring disaster prevention related information from the public communication device 4, the detection device group 5, the disaster prevention chat server 6, and the data sharing server 7, and a process of transmitting the acquired disaster prevention related information, etc. to the electronic terminal 2.

[0020] 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.

[0021] 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.

[0022] 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 occurring.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] The data sharing server 7 is a server for collecting disaster prevention related information sent from multiple users registered in the disaster prevention system 1 and transmitting the collected disaster prevention related information to each user, thereby sharing the disaster prevention related information among users. For example, the disaster prevention related information in the data sharing server 7 may include rainfall and soil moisture content acquired by other users. The rainfall acquired by other users may be, for example, the rainfall detected by a rain gauge installed in the target area by other users of the disaster prevention system 1. The soil moisture content acquired by other users may be the soil moisture content of a point selected by the other users or a mountain nearby.

[0028] When disaster warnings issued by public institutions and other organizations cover a wide area, there is a tendency for discrepancies between the content of the warning and the actual local conditions in some areas. Weather conditions are particularly changeable 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. When such warnings are suddenly issued that do not necessarily reflect the actual conditions of the user's location, it is difficult for residents to recognize the urgency of the situation. In contrast, the disaster prevention system 1 according to this embodiment enhances users' sense of responsibility and enables them to proactively respond to potential disaster situations.

[0029] 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 26 of the electronic terminal 2.

[0030] As shown in FIG. 2, the electronic terminal 2 includes a processing unit 20, an input unit 21, a display unit 22, a storage unit 23, and a communication I / F unit 24.

[0031] The processing unit 20 is configured by, for example, a processor 261, and is the central part of the computer 26 that performs processing such as calculations and controls required for the operation of the electronic terminal 2, and performs various calculations and processing.

[0032] As shown in FIG. 3 , the computer 26 of the electronic terminal 2 includes a processor 261, a ROM 262 and a RAM 263 as main storage devices, a bus 264, and the like. The processor 261 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 261 may be a combination of these. The processor 261 may also be a combination of these with a hardware accelerator or the like. The processor 261 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 262 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 circuitry of the processor 261. The configuration of the processing unit 20's disaster prevention display processing function will be described later.

[0033] 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 25 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.

[0034] The display unit 22 is a user interface electrically connected to the processing unit 20. The display unit 22 is configured with a display 25. A disaster prevention application according to this embodiment is started by a user's operation. A disaster prevention menu is displayed on the display unit 22, in which disaster prevention-related information is divided into multiple items. The application has SNS (Social Networking Service) functions (message sending / receiving functions, timeline functions, etc.).

[0035] The display unit 22 displays according to two display modes: a normal mode and an emergency mode. The normal mode is a display mode that displays display items 8 corresponding to normal times. The emergency mode is a display mode that displays display items 9 corresponding to emergencies. The multiple items that make up display items 8 and 9 include a disaster prevention menu. The disaster prevention menu of display items 9 includes emergency items, but the disaster prevention menu of display items 8 does not include emergency items.

[0036] In the disaster prevention system 1, the display mode of the display unit 22 of the electronic terminal 2 is switched based on a mode switching reference condition (switching reference condition) set based on a user's selection. When the display mode is switched, all of the items constituting the display items 8 or 9 may be changed, or only some of the multiple items constituting the display items 8 or 9 may be changed. For example, when switching from normal mode to emergency mode, one or more items from the disaster prevention menu of the display items 8 may be switched to emergency items. In this embodiment, when the display mode is switched, only some of the multiple items constituting the display items 8 or 9 are changed.

[0037] Next, an example of the display content displayed on the display unit 22 of the electronic terminal 2 on which a disaster prevention application is installed as a program for executing the disaster prevention display process of the disaster prevention system 1 according to this embodiment will be described with reference to Fig. 4 and Fig. 5. Fig. 4 is a schematic diagram showing an example of the display content displayed on the display unit 22 of the electronic terminal 2 in normal mode. Fig. 5 is a schematic diagram showing an example of the display content displayed on the display unit 22 of the electronic terminal 2 in emergency mode.

[0038] The disaster prevention display process includes a display mode switching process and a display level change process. The display mode switching process is a process for switching the display mode of the display unit 22 between a normal mode and an emergency mode. The display level change process is a process for changing the type and color of the display items 9 of the display unit 22 according to the disaster alert level when the display mode is the emergency mode.

[0039] An example of the display contents in the normal mode will be described below. As shown in Fig. 4, the display items 8 in the normal mode include, for example, a back icon 80, a search icon 81, a text icon 82, a menu icon 83, disaster prevention icons 84 to 89 as a disaster prevention menu, and a menu 90.

[0040] 4, a back icon 80 is displayed in the upper left of the display screen. Tapping the back icon 80 returns to the previous page. A menu icon 83 for displaying or hiding the main operation menu, a search icon 81, and a text icon 82 are displayed in the upper right of the display screen.

[0041] Disaster prevention icons 84 to 89 are displayed from the center down on the display screen shown in FIG. 4. Disaster prevention icon 84 is an icon for the user to input rainfall data. The rainfall data input into disaster prevention icon 84 is sent to the data sharing server 7. Disaster prevention icon 85 is an icon for accessing the data sharing server 7 or the disaster prevention server 3 and viewing other users' rainfall and soil moisture data. Disaster prevention icon 86 is an icon for accessing the public communication device 4 or the disaster prevention server 3 and viewing information such as weather information, advisories, and warnings for the target area. Disaster prevention icon 87 is an icon for modifying and deleting history entered by the user. Disaster prevention icon 88 is an icon for accessing the disaster prevention chat server 6 and chatting with other users. Disaster prevention icon 89 is an icon for inputting opinions and requests regarding the services of the disaster prevention system 1. A menu 90 displaying a message regarding the timing to start evacuation is displayed at the bottom of the display screen shown in FIG. 4.

[0042] An example of the display contents in the emergency mode will be described below. As shown in Fig. 5, the display items 9 in the emergency mode include, for example, menus 91 and 92, which are emergency items in the disaster prevention menu, and the same return icon 80 as the display items 8 in the normal mode, a menu icon 83, and disaster prevention icons 86, 85, and 88, which are disaster prevention menus, and a menu 90.

[0043] Menu 91 is displayed relatively large at the top of the display screen shown in FIG. 5. Alerts and warnings sent from public communication devices 4 and the like are displayed in menu 91. Menu 91 is an area where the timeline function of the SNS is implemented, and messages posted from outside (for example, municipalities, specific businesses, etc.) are displayed. Menu 92 is displayed relatively large in the center of the display screen shown in FIG. 5. Alerts and warnings sent from public communication devices and the like, disaster prevention-related information for the target area, and the like are displayed in menu 92. The background color of menu 92 shown in FIG. 5 is displayed in purple, which is different from the other display items 9. Purple indicates that the disaster alert level is 4. The type and / or color of display items 9 in emergency mode are changed depending on the alert level. Specifically, the colors of display items 9 are set as follows: white when the disaster alert level is 1, yellow when the alert level is 2, red when the alert level is 3, purple when the alert level is 4, and black when the alert level is 5. In this embodiment, in the emergency mode, the display content and / or background color of the warning alert shown in the emergency section is changed according to the publicly established alert level.

[0044] Furthermore, although not shown in Fig. 5, in emergency mode, when a predetermined condition is met, a pop-up is displayed to encourage disaster prevention actions. As shown in Fig. 4 and Fig. 5, the display items 9 in emergency mode have a different configuration from the display items 8 in normal mode, and are laid out in a way that allows the urgency to be recognized more intuitively through visual recognition.

[0045] 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, a RAM, a 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, first setting information (setting information) and second setting information described below, mode switching reference conditions, level setting reference conditions, etc. Examples of user information include a location selected by the user, such as the user's address, a target area including the location, and user identification information such as the ID of the electronic terminal 2 itself.

[0046] 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.

[0047] As shown in FIG. 2, the processing unit 20 includes a receiving unit 201, a setting unit 202, a reference condition transmitting unit 203, a display control unit 204, and a disaster prevention related information acquiring unit 205.

[0048] The reception unit 201 executes a process of receiving input of first setting information and second setting information to the input unit 21 by user operation. The first setting information is information for setting mode switching reference conditions, and is information selected by the user. The mode switching reference conditions are conditions that serve as selection criteria for setting the display mode of the display unit 22 to either the normal mode or the emergency mode. That is, in the disaster prevention system 1, the mode switching reference conditions for the display mode are determined by the user and can be changed by the user as appropriate.

[0049] The mode switching reference condition may be, for example, a condition for switching the display mode from the normal mode to the emergency mode at a timing when it is not necessary to actually take evacuation action but it is necessary to prepare for evacuation action, such as by checking an evacuation destination and an evacuation route.Also, for example, the mode switching reference condition may be a condition for switching the display mode from the normal mode to the emergency mode at a timing when a disaster has not yet occurred and it is necessary to increase disaster preparedness, such as by paying attention to the latest disaster prevention related information.

[0050] The first setting information for setting the mode switching reference condition may be, for example, information that selects the normal mode when the amount of rainfall, the moisture content of the soil, or the water level of a river in the target area is below a predetermined threshold, and selects the emergency mode when the amount of rainfall, the moisture content of the soil, or the water level of a river is equal to or greater than the predetermined threshold. The predetermined threshold may be, for example, 80 mm / h for the amount of rainfall, 60% for the water content of the soil, or a water level of a river that is 1.0 m lower than the flood initiation level at which the river begins to overflow.

[0051] The first setting information is, for example, a data sheet containing information about evacuation plans in the event of a disaster, and may be an evacuation plan table that chronologically organizes disaster prevention actions that the user himself / herself will take depending on the situation.

[0052] The second setting information is information for setting a level setting reference condition in the display level change process. The level setting reference condition is a reference condition for setting the type of display item 9 in emergency mode, the content of the advisory warning for the emergency item, and the background color. The second setting information may be, for example, information associating advisory warnings and alert levels established by the Japan Meteorological Agency, or information associating a rainfall value, a soil moisture content value, the presence or absence and number of evacuation start messages from other users, and alert levels selected by the user. The second setting information in this embodiment is information associating advisory warnings and alert levels established by the Japan Meteorological Agency, and information associating the presence or absence and number of evacuation start messages from other users and alert levels.

[0053] The setting unit 202 executes a process of setting a mode switching reference condition based on the first setting information. The setting unit 202 sets the mode switching reference condition by reading and reflecting the first setting information input by the user. The setting unit 202 also executes a process of setting a level setting reference condition based on the second setting information. The setting unit 202 sets the level setting reference condition by reading and reflecting the second setting information input by the user.

[0054] The reference condition transmission unit 203 executes a process of transmitting the mode switching reference condition and the level setting reference condition set by the setting unit 202 to the disaster prevention server 3 via the communication unit I / F 24. In this embodiment, the reference condition transmission unit 203 links the user information of the electronic terminal 2 to the mode switching reference condition and transmits the linked information to the disaster prevention server 3.

[0055] The display control unit 204 executes processing to control the display of the display unit 22. The display control unit 204 executes processing to control, for example, the information to be displayed on the display unit 22, the display mode of the display unit 22, and the types and colors of the display items 8 and 9.

[0056] The display control unit 204 executes a process of controlling the display unit 22 to switch the display mode based on, for example, a display mode selection result transmitted from the disaster prevention server 3. When the set display mode is the normal mode and the display mode selection result transmitted from the disaster prevention server 3 is the emergency mode, the display control unit 204 controls the display unit 22 to switch the display mode to the emergency mode. In this embodiment, when the display mode of the display unit 22 is the normal mode and the display control unit 204 receives a control signal from the disaster prevention server 3 to switch the display mode from the normal mode to the emergency mode, the display control unit 204 switches the display mode of the display unit 22 from the normal mode to the emergency mode based on the control signal. Also, for example, when the set display mode is the emergency mode and the display mode selection result transmitted from the disaster prevention server 3 is the normal mode, the display control unit 204 controls the display unit 22 to switch the display mode to the normal mode.

[0057] Furthermore, when the set display mode is the emergency mode, the display control unit 204 performs processing to change the display content and background color of the advisory alert in the emergency item displayed on the display unit 22. In this embodiment, the display control unit 204 changes the display content and background color of the advisory alert in the menu 92, which is an emergency item among the display items 9, according to the alert level of the advisory alert determined by the disaster prevention server 3. When the display mode is the emergency mode, the display control unit 204 displays disaster prevention related information transmitted from the disaster prevention server 3 on the display unit 22. For example, the display control unit 204 may display disaster prevention related information such as the advisory alert that triggered the change in the alert level, the soil moisture content, and the amount of rainfall.

[0058] 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 .

[0059] Next, the functional configuration of the disaster prevention server 3 will be described with reference to Fig. 6 and Fig. 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 33 of the disaster prevention server 3.

[0060] As shown in FIG. 6, the disaster prevention server 3 includes a processing unit 30, a storage unit 31, and a communication I / F unit 32.

[0061] The processing unit 30 is configured by, for example, a processor 331, and is the central part of the computer 33 that performs processing such as calculations and controls required for the operation of the disaster prevention server 3, and performs various calculations and processing.

[0062] As shown in FIG. 7 , the computer 33 of the disaster prevention server 3 includes a processor 331, a ROM 332 serving as a main storage device, a RAM 333, a bus 334, and the like. The processor 331 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 331 may be a combination of these. The processor 331 may also be a combination of these with a hardware accelerator or the like. The processor 331 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 332, the RAM 333, or an auxiliary storage device that is part of the storage unit 31. Note that some or all of these programs may be incorporated into the circuitry of the processor 331. The configuration of the processing unit 30 related to the disaster prevention display processing function will be described later.

[0063] The storage unit 31 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 31 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, mode switching criteria conditions transmitted from the electronic terminal 2, level setting criteria conditions, etc.

[0064] The communication I / F unit 32 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, the data sharing server 7, etc. via the communication I / F unit 32 so as to be able to communicate with them.

[0065] 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 display mode selection unit (determination unit) 303, an alert level determination unit 304, and a transmission processing unit 305.

[0066] The reference condition acquisition unit 301 executes a process of acquiring, via the communication I / F, the mode switching reference conditions and the level setting reference conditions transmitted from the electronic terminal 2 via the communication network NW. In this embodiment, the reference condition acquisition unit 301 acquires the mode switching reference conditions and the level setting reference conditions, as well as user information linked to the mode switching reference conditions and the level setting reference 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 mode switching reference conditions and the level setting reference conditions.

[0067] 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 detection device group 5, the disaster prevention chat server 6, and the data sharing server 7 via the communication network NW.

[0068] The display mode selection unit 303 executes a process for determining whether the display mode of the display unit 22 of the electronic terminal 2 should be set to the normal mode or the emergency mode based on a comparison result between the mode switching reference 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, if the mode switching condition is to switch to the emergency mode when the amount of rainfall is equal to or greater than a predetermined threshold, the display mode selection unit 303 selects the emergency mode when the disaster prevention-related information acquisition unit 302 acquires disaster prevention-related information indicating that the amount of rainfall in the target area is equal to or greater than the threshold. That is, when a disaster prevention application is launched, a disaster prevention menu is displayed on the display unit 22, and the display mode is the normal mode, the display mode selection unit 303 determines whether the mode switching reference condition acquired by the reference condition acquisition unit 301 for switching to the emergency mode is satisfied. If the display mode selection unit 303 determines that the mode reference condition is satisfied, it determines to switch the display mode from the normal mode to the emergency mode.

[0069] The alert level determination unit 304 executes a process of determining an alert level for a disaster when the display mode of the display unit 22 is selected to be the emergency mode by the display mode selection unit 303. In this embodiment, the alert level determination unit 304 determines the alert level based on a comparison result between the level setting reference 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, the alert level determination unit 304 may determine the alert level as 1 when early warning information is issued in the target area, as 2 when a heavy rain advisory or the like is issued, as 3 when one evacuation start message of other user evacuation information is transmitted, as 4 when landslide warning information or the like is issued, and as 5 when a heavy rain emergency warning is issued.

[0070] The transmission processing unit 305 executes a process of transmitting the display mode selection result by the display mode selection unit 303 and the disaster prevention-related information acquired by the disaster prevention-related information acquisition unit 302 to the electronic terminal 2. When the display mode selection unit 303 selects the display mode as the emergency mode, the transmission processing unit 305 executes a process of transmitting the alert level determination result determined by the alert level determination unit 304 to the electronic terminal 2. Upon receiving the display mode selection result, the electronic terminal 2 controls the display unit 22 to switch the display mode in accordance with the selection result. In this embodiment, for example, when the display mode selection unit 303 determines that a mode switching reference condition for switching to the emergency mode is satisfied while the display mode is the normal mode, the transmission processing unit 305 transmits a control signal to the electronic terminal 2 to switch the display mode from the normal mode to the emergency mode. Then, the electronic terminal 2 switches the display mode of the display unit 22 from the normal mode to the emergency mode based on the control signal received from the disaster prevention server 3. In addition, when the display mode is in emergency mode and the electronic terminal 2 receives the alert level determination result, it controls the display unit 22 to set the display content and background color of the warning alert in the menu 92, which is an emergency item among the display items 9, to display content and color corresponding to the alert level.

[0071] Next, an example of the flow of disaster prevention display processing in the disaster prevention system 1 will be described with reference to FIGS.

[0072] First, the flow of communication between the electronic terminal 2 and the disaster prevention server 3 in the display mode switching process of the disaster prevention display process 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 display mode switching process.

[0073] As shown in FIG. 8, in step S1, the electronic terminal 2 receives the first setting information input to the input unit 21 by the user.

[0074] In step S2, the electronic terminal 2 sets the mode switching reference condition based on the first setting information received in step S1.

[0075] In step S3, the electronic terminal 2 transmits to the disaster prevention server 3 the mode switching criteria conditions set in step S2 and the user information of the electronic terminal 2.

[0076] 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.

[0077] In step S5, the disaster prevention server 3 selects one of the normal mode and the emergency mode by comparing the mode switching criteria acquired in step S3 with the disaster prevention-related information acquired in step S4. For example, the normal mode may be selected when the amount of rainfall in the target area is less than a predetermined threshold, and the emergency mode may be selected when the amount of rainfall is equal to or greater than the predetermined threshold.

[0078] In step S6, the disaster prevention server 3 transmits to the electronic terminal 2 the selection result of the display mode selected in step S5.

[0079] In step S7, the electronic terminal 2 receives the selection result transmitted in step S6, and sets the display mode of the display unit 22 to the display mode indicated in the selection result.

[0080] Next, an example of the display mode switching process of the disaster prevention display process executed by the processing unit 20 of the electronic terminal 2 when the display mode is set to the normal mode will be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of the display mode switching process executed by the electronic terminal 2 when the display mode is the normal mode. Before executing the process shown in Fig. 9, the electronic terminal 2 is in a state where a disaster prevention application has been started and a disaster prevention menu in which disaster prevention related information is divided into multiple items is displayed on the display unit 22.

[0081] 9, the display mode of the display unit 22 of the electronic terminal 2 before the display mode switching process is executed is set to the normal mode. In step S11, the accepting unit 201 of the processing unit 20 accepts the first setting information input to the input unit 21 by a user operation.

[0082] In step S12, the setting unit 202 sets the mode switching reference condition based on the first setting information received in step S11.

[0083] In step S13, the reference condition transmission unit 203 associates the mode switching reference condition set in step S12 with the user information of the electronic terminal 2, and transmits the associated information to the disaster prevention server 3 via the communication network NW.

[0084] In step S14, the display control unit 204 acquires the display mode selection result and disaster prevention related information from the disaster prevention server 3 via the communication I / F unit 24.

[0085] In step S15, the display control unit 204 determines whether the selection result acquired in step S14 is the emergency mode. If the display control unit 204 determines that the selection result is the emergency mode (YES in step S15), the process proceeds to step S17. On the other hand, if the display control unit 204 determines that the selection result is the normal mode (NO in step S15), the process proceeds to step S16.

[0086] In step S16, the display control unit 204 determines whether or not a user operation to change to the emergency mode has been accepted by the accepting unit 201. If the display control unit 204 determines that a user operation to change to the emergency mode has been accepted by the accepting unit 201 (YES in step S16), the display control unit 204 proceeds to step S17. On the other hand, if the display control unit 204 determines that a user operation to change to the emergency mode has not been accepted by the accepting unit 201 (NO in step S16), the display control unit 204 ends the disaster prevention display process.

[0087] In step S17, the display control unit 204 controls the display unit 22 to switch the display mode of the display unit 22 from the normal mode to the emergency mode.

[0088] In step S18, the display control unit 204 displays disaster prevention related information on the emergency mode display unit 22. After that, the processing unit 20 ends the display mode switching process.

[0089] Next, an example of a display mode switching process of the disaster prevention display process 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 the display mode switching process executed by the processing unit 30 of the disaster prevention server 3.

[0090] As shown in FIG. 10, in step S21, the reference condition acquisition unit 301 acquires the mode switching reference condition and user information transmitted from the electronic terminal 2 in step S13 via the communication network NW.

[0091] In step S22, 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, the disaster prevention chat server 6, and the data sharing server 7 via the communication network NW.

[0092] In step S23, the display mode selection unit 303 compares the mode switching criteria acquired in step S21 with the latest disaster prevention related information acquired in step S22, and selects the display mode of the display unit 22 based on the comparison result.

[0093] In step S24, the transmission processing unit 305 transmits the selection result of the display mode selected in step S23 and the disaster prevention related information acquired in step S22 to the electronic terminal 2 via the communication network NW. Thereafter, the processing unit 30 ends the display mode switching process.

[0094] Next, an example of a display mode switching process executed by the processing unit 20 of the electronic terminal 2 when the display mode is set to the emergency mode will be described with reference to Fig. 11. Fig. 11 is a flowchart showing an example of a disaster prevention display process executed by the electronic terminal 2 when the display mode is the emergency mode. Note that steps S11 to S14 shown in Fig. 11 are the same processes as steps S11 to S14 shown in Fig. 9, and therefore description thereof will be omitted. Before executing the process shown in Fig. 11, the electronic terminal 2 is in a state where a disaster prevention application has been started and a disaster prevention menu in which disaster prevention-related information is divided into multiple items is displayed on the display unit 22.

[0095] 11, the display mode of the display unit 22 of the electronic terminal 2 before executing the display mode switching process is set to the emergency mode. As shown in FIG. 11, in step S31, the display control unit 204 determines whether the selection result acquired in step S14 is the normal mode. If the display control unit 204 determines that the selection result is the normal mode (YES in step S31), the process proceeds to step S32. On the other hand, if the display control unit 204 determines that the selection result is the emergency mode (NO in step S31), the display mode switching process ends.

[0096] In step S32, the display control unit 204 controls the display unit 22 to switch the display mode of the display unit 22 from the emergency mode to the normal mode. After that, the processing unit 20 ends the display mode switching process.

[0097] Next, an example of the display level change process of the disaster prevention display process will be described. Fig. 12 is a flowchart showing an example of the display level change process executed by the electronic terminal 2 when the display mode is the emergency mode. In the example shown in Fig. 10, the display mode of the display unit 22 of the electronic terminal 2 before executing the display level change process is set to the emergency mode.

[0098] 12, in step S41, the level setting reference condition is transmitted. The reference condition transmission unit 203 associates the level setting reference condition set by the setting unit 202 with the user information of the electronic terminal 2, and transmits the result to the disaster prevention server 3 via the communication network NW.

[0099] In step S42, the display control unit 204 acquires the alert level determination result and disaster prevention related information from the disaster prevention server 3.

[0100] In step S43, the display control unit 204 determines whether the alert level determination result acquired in step S42 differs from the alert level currently set in the display unit 22. If the display control unit 204 determines that the alert level determination result differs from the alert level set in the display unit 22 (YES in step S42), the display control unit 204 proceeds to step S44. Then, the display control unit 204 changes the display content and background color of the advisory alert in the emergency item among the display items 9 to the display content and color corresponding to the alert level acquired in step S42, and proceeds to step S45. On the other hand, if the display control unit 204 determines that the alert level determination result is the same as the alert level set in the display unit 22 (NO in step S42), the display control unit 204 skips the processing of step S44 and proceeds to step S45.

[0101] In step S45, the display control unit 204 displays the disaster prevention related information on the display unit 22. After that, the processing unit 20 ends the display level change process.

[0102] Next, an example of the display level change processing executed by the processing unit 30 of the disaster prevention server 3 will be described with reference to Fig. 13. Fig. 13 is a flowchart showing an example of the display level change processing executed by the processing unit 30 of the disaster prevention server 3.

[0103] As shown in FIG. 13, in step S51, the reference condition acquisition unit 301 acquires the level setting reference condition transmitted in step S41 via the communication network NW.

[0104] In step S52, the disaster prevention related information acquisition unit 302 acquires disaster prevention related information via the communication network NW.

[0105] In step S53, the alert level determination unit 304 determines whether the disaster prevention related information acquired in step S52 is the issuance of a heavy rain emergency warning or an emergency safety assurance. If the disaster prevention related information is the issuance of a heavy rain emergency warning or an emergency safety assurance (YES in step S53), the alert level determination unit 304 determines that alert level 5 should be displayed, and proceeds to step S59. On the other hand, if the alert level determination unit 304 determines that the disaster prevention related information is not the issuance of a heavy rain emergency warning or an emergency safety assurance (NO in step S53), the process proceeds to step S54.

[0106] In step S54, the alert level determination unit 304 determines whether the disaster prevention related information acquired in step S52 is an evacuation order. If the alert level determination unit 304 determines that the disaster prevention related information is an evacuation order (YES in step S54), it determines that alert level 4 should be displayed, and proceeds to step S59. On the other hand, if the alert level determination unit 304 determines that the disaster prevention related information is not an evacuation order (NO in step S54), it proceeds to step S55.

[0107] In step S55, the alert level determination unit 304 determines whether the disaster prevention related information acquired in step S52 is a landslide disaster warning. If the alert level determination unit 304 determines that the disaster prevention related information is a landslide disaster warning (YES in step S55), it determines that alert level 4 should be displayed, and proceeds to step S59. On the other hand, if the alert level determination unit 304 determines that the disaster prevention related information is not a landslide disaster warning (NO in step S55), it proceeds to step S45.

[0108] In step S56, the alert level determination unit 304 determines whether the disaster prevention related information acquired in step S52 is an evacuation warning for elderly people, etc., a heavy rain warning, or a flood warning. If the alert level determination unit 304 determines that the disaster prevention related information is an evacuation warning for elderly people, etc., a heavy rain warning, or a flood warning (YES in step S56), it determines that alert level 3 should be displayed, and proceeds to step S59. On the other hand, if the alert level determination unit 304 determines that the disaster prevention related information is not an evacuation warning for elderly people, etc., a heavy rain warning, or a flood warning (NO in step S56), it proceeds to step S57.

[0109] In step S57, the alert level determination unit 304 determines whether the disaster prevention related information acquired in step S52 is an evacuation start message of other user's evacuation information. If the alert level determination unit 304 determines that the disaster prevention related information is other user's evacuation information (YES in step S57), it determines to display alert level 3 and proceeds to step S59. On the other hand, if the alert level determination unit 304 determines that the disaster prevention related information is not other user's evacuation information (NO in step S57), it proceeds to step S58.

[0110] In step S58, the alert level determination unit 304 determines whether the disaster prevention related information acquired in step S52 is a heavy rain advisory or a flood advisory. If the alert level determination unit 304 determines that the disaster prevention related information is a heavy rain advisory or a flood advisory (YES in step S58), it determines that alert level 2 should be displayed, and proceeds to step S59. On the other hand, if the alert level determination unit 304 determines that the disaster prevention related information is not a heavy rain advisory or a flood advisory (NO in step S58), it determines that alert level 1 should be displayed, and proceeds to step S59.

[0111] In step S59, the transmission processing unit 305 transmits the alert level determination result determined by the alert level determination unit 304 and the disaster prevention related information acquired in step S52 to the electronic terminal 2. Thereafter, the processing unit 30 ends the display level change process.

[0112] According to the embodiment described above, the following effects are achieved.

[0113] The program of this embodiment is a program that executes a display control process in which a disaster prevention application is launched on computer 26, 33, a disaster prevention menu in which disaster prevention related information is divided into multiple items is displayed on display unit 22, and the program compares the mode switching criteria conditions for switching one or more items from the disaster prevention menu to emergency items with the disaster prevention related information of the target area, and if the mode switching criteria conditions are satisfied, executes a display control process in which one or more items from the disaster prevention menu are switched to emergency items, and the mode switching criteria conditions and target area are set in advance by the user's own selection.

[0114] This allows the display mode to be switched between normal mode and emergency mode based on the mode switching criteria determined based on the user's own selection and disaster prevention-related information for the area selected by the user, allowing the user to take a more proactive approach to situations where a disaster may occur with a sense of ownership.This makes disaster prevention actions more personal, leading to evacuation at the appropriate time.

[0115] In addition, in the program according to this embodiment, the emergency items include warnings and alerts related to natural disasters, and in the display control process, when the disaster prevention menu is switched to the emergency items, the display content and / or background color of the warning and alert are changed according to the publicly established alert level.

[0116] This allows users to intuitively grasp urgent information, which is expected to simplify understanding of the situation.

[0117] In addition, in the program according to this embodiment, the disaster prevention menu includes weather information, warnings and alerts, soil moisture content, and other user evacuation information relating to the evacuation status of other users.

[0118] This allows the display mode to be switched at a more appropriate time, taking into account various disaster prevention information for the area selected by the user. For example, even if the weather improves after heavy rain, emergency mode will be maintained if there is high moisture content in the soil of mountains, etc., so the user can be alert to sudden disasters such as landslides.

[0119] The disaster prevention system 1 according to this embodiment is a disaster prevention system 1 including an electronic terminal 2 having a display unit 22 that displays disaster prevention related information, and a disaster prevention server 3 that can communicate with the electronic terminal 2. The electronic terminal 2 has a disaster prevention application started, and a disaster prevention menu configured with disaster prevention related information divided into a plurality of items displayed on the display unit 22. The electronic terminal 2 includes a reception unit 201 that receives setting information for switching one or more items from the disaster prevention menu to emergency items, a setting unit 202 that sets a mode switching reference condition based on the setting information, and a reference condition transmission unit 203 that transmits the mode switching reference condition to the disaster prevention server 3. The disaster prevention server 3 includes a reference condition acquisition unit 301 that acquires the mode switching reference condition from the electronic terminal 2, and a reference condition transmission unit 203 that transmits the mode switching reference condition to the disaster prevention server 3. The electronic terminal 2 includes a disaster prevention related information acquisition unit 302 that acquires disaster prevention related information for a target area, a display mode selection unit 303 that compares the mode switching reference conditions acquired by the reference condition acquisition unit 301 with the disaster prevention related information acquired by the disaster prevention related information acquisition unit 302 and determines whether the mode switching reference conditions are met, and a transmission processing unit 305 that, when the display mode selection unit 303 determines that the mode switching reference conditions are met, transmits a control signal to the electronic terminal 2 to switch one or more items on the disaster prevention menu to emergency items, and the electronic terminal 2 includes a display control unit 204 that switches one or more items on the disaster prevention menu to emergency items based on the control signal received from the disaster prevention server 3, and the setting information is selected by the user.

[0120] Furthermore, the display method according to this embodiment is a display method that includes a display control process in which a disaster prevention application is launched, and a disaster prevention menu in which disaster prevention related information is divided into multiple items is displayed on the display unit 22, and a mode switching standard condition for switching one or more items from the disaster prevention menu to emergency items is compared with the disaster prevention related information of the target area, and if the mode switching standard condition is satisfied, one or more items from the disaster prevention menu are switched to emergency items, and the mode switching standard condition and the target area are set in advance by the user's own selection.

[0121] 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.

[0122] In the above embodiment, the disaster prevention system 1 is configured to execute the display level change process, but it may be configured to execute only the display mode switching process and not the display level change process. That is, the setting unit 202 of the electronic terminal 2 may not set the level setting reference condition, and the disaster prevention server 3 may not have the alert level determination unit 304.

[0123] 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 mode switching reference condition that includes, as a parameter, the disaster prevention related information detected by the mountain camera.

[0124] For example, the disaster prevention system 1 may execute a process for presenting a proposed revision of the mode switching reference condition to the user of the electronic terminal 2 when the mode switching reference condition is satisfied. FIG. 14 is a block diagram illustrating the configuration of hardware and functional blocks of the disaster prevention server 3 in the disaster prevention system 1 according to a modified example. For example, as illustrated in FIG. 14, the disaster prevention server 3 may be configured to include a revision proposal creation unit 306 that determines whether the mode switching reference condition is appropriate as a condition for switching the display mode of the display unit 22 and, if determined to be inappropriate, creates a proposed revision of the mode switching reference condition. The revision proposal creation unit 306 may, for example, determine whether the mode switching reference condition is appropriate by comparing a validity determination reference value with the mode switching reference condition. The validity determination reference value may be, for example, a publicly designated reference value for issuing a warning or alert in the user's target area (hereinafter referred to as the public institution's reference value) set by the Japan Meteorological Agency or a reference value previously set in the disaster prevention system 1. For example, the revision proposal creation unit 306 may determine that a value within a predetermined numerical range from the public institution's reference value is appropriate, and that a value outside the predetermined numerical range is inappropriate. Then, the amendment proposal creating unit 306 may create the reference value of the public institution as an amendment proposal to the mode switching reference condition. Furthermore, when an amendment proposal to the mode switching reference condition is created by the amendment proposal creating unit 306, the transmission processing unit 305 may execute a process of transmitting the amendment proposal to the electronic terminal 2. Having received the amendment proposal, the electronic terminal 2 may present the amendment proposal to the user via the display unit 22. [Explanation of symbols]
