Description

[Technical Field]

[0001] The present invention relates to an information terminal device and program that are effective when used in a location information system or disaster prevention monitoring system that can report the location of a mobile terminal or other device being monitored within a facility such as a building that serves as a monitoring area, and in particular to a technology that is effective when applied to the function of changing the screen display of an information terminal device in an emergency such as a fire. [Background technology]

[0002] Conventionally, there are location search systems and location information systems that install transmitters such as beacons that wirelessly transmit wireless communication repeaters or device-specific identification information as location detection information within a facility such as a building, determine the location of a mobile terminal that receives the signal, and display the location on a map. Also, an invention has been proposed that combines a fire detection system that detects the occurrence of a fire based on signals from fire detectors installed in various locations within the facility with the location information system, and displays information such as the location of a fire on a map that indicates the location of a mobile terminal based on fire detection information (see, for example, Patent Document 1).

[0003] In the invention of Patent Document 1, an application program (location information display app) that executes a process of displaying a floor plan image on the screen based on floor plan information transmitted from a location information server is stored in a mobile device, and by launching this location information display app, a mark indicating the location of the mobile device owner within a monitoring area where a beacon is installed and the location of a fire is displayed on the screen of the mobile device. On smartphones and the like, such apps are generally displayed as an icon representing the app alongside other apps on the home screen, and the app is launched by touching the icon with a finger.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-201699 [Patent Document 2] Japanese Patent Application Laid-Open No. 2017-49926 Summary of the Invention [Problem to be solved by the invention]

[0005] On the home screen of a conventional smartphone (hereinafter referred to as a smartphone), multiple app icons, either initially set by the manufacturer or set by the user, are displayed side by side, and once the icon display position (screen layout) is set, it remains fixed unless the settings are changed. Furthermore, icons of less frequently used apps are hidden behind the basic home screen and can only be displayed by swiping the screen or pressing a button to display a list of all apps. Therefore, when a user wants to use such an app, it takes time to find the icon, operate it, and launch the app. Furthermore, the app that the user wants to use may change depending on the user's activity status, but the fixed icon layout on the home screen of a conventional smartphone can sometimes be inconvenient.

[0006] Patent document 2 describes an invention that focuses on the fact that the apps that people want to use differ between business activities and private activities, and that displaying all app icons on the home screen would make the screen cluttered. This invention prepares multiple home screens in advance, and switches the layout of the home screen displayed on the smartphone depending on the location and time of day. However, switching based on location and time is intended only for normal times and is not suitable for emergencies. Also, as in Patent Document 1, there is an invention that allows simple information to be obtained by push notification in an emergency, but if the notification is dismissed without transitioning to the detailed information screen of the app, it is necessary to search for and launch the app by oneself, which poses a problem that it is difficult to find apps that are not normally used.

[0007] The present invention has been made with an eye on the above-mentioned problems, and its purpose is to provide an information terminal device and program that allows users to quickly understand and deal with an event (emergency situation) by quickly operating app icons and operation buttons to be used in an emergency, and that can automatically change the display mode on the screen to prevent accidental operation during normal times.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, an embodiment of a mobile terminal as an information terminal device according to the present invention will be described with reference to the drawings. Fig. 1 is a block diagram showing an example of a schematic configuration of a location information system that is effective when using a mobile terminal according to this embodiment. As shown in FIG. 1, the location information system of this embodiment includes beacons (transmitters) 10 distributed at multiple locations within a predetermined area inside a building, mobile terminals 20 capable of receiving signals (radio waves) from the beacons 10, and a location information server 40 that communicates data with the mobile terminals 20 via a mobile phone base station 30 and a communication network N such as the Internet.

[0021] The location information system of this embodiment is configured to include a fire receiver 60 capable of receiving fire detection signals from fire detectors 50 installed at multiple locations within a predetermined area inside a building, a fire information server 80 that communicates data with the fire receiver 60 via a gateway (general repeater) 70 and a communication network N, and a push notification system 90 that can directly send messages to the mobile terminal 20 via the communication network N. The communication network N may be a public communication network, a network using secure lines, or a network with partially independent lines.

[0022] The push notification system 90 can be configured with a server (push notification support server) 91 equipped with an API (application programming interface) function, a function for sending push notifications, and a management function for managing messages to be sent and transmission times, and a storage device (database) 92 that stores programs and the like. An existing system can also be used for the push notification system 90. In this case, the push notification system 90 can notify information such as earthquake alerts in response to requests from other systems, in addition to notifying of fires, which will be described later, even when the mobile device is not running an app. The location information server 40 and the push notification support server 91 may be configured as a single support server. Similarly, the fire information server 80 may be configured as a shared support server with the location information server 40 and the push notification support server 91.

[0023] The communication method of the beacons 10 that transmit wireless signals (unique information such as device IDs and facility information) to the mobile terminals 20 can be any known communication method, such as Bluetooth (registered trademark) communication, wireless LAN such as WiFi conforming to the IEEE 802.11 standard, infrared communication, visible light communication, etc. The intervals at which the beacons 10 are placed are not particularly limited, but in the following description, it is assumed that adjacent beacons 10 are placed so that their communication ranges cover the entire space within the building.

[0024] Specifically, since fire detectors 50 and sprinkler heads are originally installed at predetermined intervals within a building, it is possible to use beacons 10 that are built into or attached to these devices, or that are installed near these devices. Also, beacons that are distributed and installed at multiple locations within a predetermined area within the building may be included. The beacon 10 has a transmitter that periodically transmits its own identification information via a wireless signal to the surrounding area. The signal (beacon signal) wirelessly transmitted by the beacon 10 only needs to include at least the identification information of the beacon 10 (the device ID of the transmitter), and may further include information about the area where the beacon is installed. Information about the power source may also be included.

[0025] On the other hand, the mobile terminal 20 is an information terminal device such as a smartphone that has a receiving function for receiving signals from the beacon 10, a wireless communication function, a display unit, etc., and is composed of a control unit consisting of a microprocessor (MPU), a memory unit (internal memory) such as ROM and RAM, a display unit consisting of an LCD panel or an organic EL panel, etc., a beacon signal receiving means, and a communication unit having wireless communication means for performing wireless communication in accordance with communication standards for mobile phones. Therefore, when the mobile terminal 20 receives a signal from the beacon 10 and transmits the beacon information to the location information server 40 via the communication network N, the location information server 40 can register the location of the mobile terminal 20 as the location corresponding to the beacon 10. The mobile terminal 20 also has a function as an event occurrence detection means that detects the occurrence of a predetermined event such as a fire based on the functions of the terminal itself and information obtained from the communication unit.

[0026] The internal memory of the mobile terminal 20 stores an application program (location information display app) that performs the following processes: receiving beacon signals periodically transmitted wirelessly from the beacon 10 and extracting identification information (device ID) and the like contained in the beacon signals; detecting the received radio wave strength of the beacon signals and transmitting a set of beacon information including the identification information and the received radio wave strength, as well as identification information (terminal ID) specific to the mobile terminal itself, to the location information server 40; and displaying a floor plan (map) based on the floor plan information transmitted from the location information server 40 on the display screen.

[0027] The fire detector 50 has a function of transmitting a fire detection signal to the fire receiver 60 via the detector line 51 when it detects the occurrence of an abnormal phenomenon such as heat, smoke, flame, or hazardous gas. The fire detector 50 may be a detector of the type that transmits the fire detection signal with its own installation address attached, or a detector of the type that does not transmit the fire detection signal with its own installation address attached.

[0028] When the fire receiver 60 receives a fire detection signal from the fire detector 50, it displays a fire detection message on the display unit and controls the ringing of a district bell and the interlocking of smoke control and exhaust. Furthermore, the fire receiver 60 transmits fire information, including information on the location and time of the fire, to the fire information server 80 via the gateway 70 and the communication network N. The fire information server 80 has a database 81 that stores information on building facilities and equipment related to fires, such as fire transmitters and fire hydrants, and can transmit this information and fire location information to the location information server 40.

[0029] If the installation address of the fire detector 50 is added to the received fire detection signal, the fire receiver 60 identifies the location of the fire based on the installation address. On the other hand, if the installation address of the fire detector 50 is not added to the fire detection signal, the fire receiver 60 identifies the location of the fire based on the sensor line 51 (warning area) that transmitted the fire detection signal. Also, a system is possible in which the gateway 70 is omitted and fire information including the fire location is sent directly from the fire receiver 60 to the fire information server 80. Fire information may also be sent from a device other than the fire receiver 60.

[0030] The location information server 40 includes a database 41 that stores map information (floor plan) of each floor of a building managed by the location information server 40. The map information (floor plan information) of each floor may include the device IDs and installation location information of the beacons 10 installed on each floor. The database 41 may also store an owner information table that includes identification information (terminal ID) unique to a mobile terminal and information (attribute information of system users) on the attributes such as the authority and qualifications of system users (users, here mobile terminal owners).

[0031] When the location information server 40 receives the device ID and terminal ID of the beacon 10 from the mobile terminal 20, it calculates the current location of the mobile terminal 20 based on the device ID of the received beacon and the information stored in the database 41. Then, it reads setting information related to map information of the floor on which the mobile terminal 20 is located from the database 41, and generates floor display information by adding a mark (icon) or the like indicating the current location of the user who owns the mobile terminal 20 to the read floor plan. Then, it executes a process of transmitting the generated floor display information to the mobile terminal 20 that transmitted the terminal ID. Furthermore, it can also be transmitted to a PC 43 connected to the location information server 40 via a LAN (local area network) or a communication network N and displayed on the PC 43.

[0032] As a result, a floor plan image (see FIG. 5) with an icon or the like indicating the current location of the user who owns the mobile terminal 20 is displayed on the display unit of the mobile terminal 20 or the PC 43. Furthermore, when an icon on the displayed screen is touched or the cursor is placed over it, information about the owner of the mobile terminal 20 or the like may be displayed in a speech bubble or the like. The location information server 40 and the fire information server 80 may be configured as a single common server. The location information server 40 and the fire information server 80 may be installed adjacent to each other in a location such as a disaster prevention monitoring center, or may be installed in separate buildings or spaces. For example, the functions of the location information server 40 and the fire information server 80 may be implemented using a cloud server.

[0033] Furthermore, in the above embodiment, a system using beacon-based positioning has been exemplified as the location information system, but the present invention is not limited to this, and the location information system may be a system using other methods of positioning, such as IMES (Indoor Messaging System). That is, the transmitter is not limited to a beacon, and may be an IMES transmitter or the like. Alternatively, a system may be used in which multiple video cameras are installed in a monitoring area, and the AI ​​in the location information server 40 detects people in the monitoring area based on captured images through image processing, and the AI ​​identifies people in the images based on the people's characteristics and information in a database.

[0034] Next, using Figure 2, we will explain an outline of the communication sequence between the location information server 40 and the mobile terminal 20, between each server 40, 80 and the push notification system 90, and between the push notification system 90 and the mobile terminal 20 in the location information system of the above embodiment. In normal circumstances where there is no fire, when a mobile terminal 20 launches a general-purpose map application (location information display application) within a specified area, the mobile terminal 20 receives a device ID from a nearby beacon 10 and transmits the received device ID and its own terminal ID to the location information server 40 (#1).

[0035] Then, the location information server 40 determines the location of the mobile terminal 20 that transmitted the ID from the received beacon device ID, reads map information from the database 41, creates map data in which an icon or the like is added to the location of the terminal on the map, and transmits this to the mobile terminal 20 (#2). The mobile terminal 20 periodically (for example, every minute) transmits the beacon device ID to the location information server 40, and the location information server 40 periodically transmits the map data in response. If there are multiple mobile terminals 20 that have launched a general-purpose map app within a specified area, the location information server 40 transmits the map data to all mobile terminals 20 within the area.

[0036] Regarding the transmission of map information to the mobile terminal 20, the location information server 40 may be configured to transmit map information to mobile terminals within a specified area periodically (for example, every minute) without receiving an ID from the mobile terminal 20, or the mobile terminal 20 may be configured to operate the mobile terminal 20 or periodically transmit a request to the location information server 40, and the map information may be transmitted in response to the request. In addition, the mobile terminal 20 may be configured to send location information (ID) to the location information server 40 even when a general-purpose map application is running in the background, and further, if there are multiple mobile terminals 20, the locations of the other mobile terminals 20 may be displayed.

[0037] When a fire breaks out, fire receiver 60 detects it and transmits fire information including the occurrence and location of the fire to fire information server 80 (#3). In response, fire information server 80 transmits information about the occurrence and location of the fire to location information server 40 (#4). Then, based on the terminal IDs of the mobile terminals 20 within the area that the location information server 40 has already identified, it refers to the owner information table in the database 41 to determine the attributes or type of the mobile terminal owner, selects the mobile terminals to be notified of the fire outbreak, and requests the push notification system 90 to send a push notification of the fire outbreak to the selected mobile terminals (#5).

[0038] Upon receiving the request, the push notification system 90 immediately (for example, within one second) sends a push notification to the selected mobile terminal informing it of the occurrence of a fire (#6). In response, the mobile terminal 20 that received the push notification activates its speaker and displays a message informing it of the occurrence of a fire on its display (#7). This allows the mobile terminal owner to quickly learn of the occurrence of a fire. Thereafter, in a state in which the application is started by operating the message displayed by the push notification or by operating the icon of the location information display application, location information server 40, at the time of regular transmission, creates map data (fire-point-marked map information) with an icon indicating the current location of mobile terminal 20 and an icon indicating the fire at the location where the fire has occurred, and transmits this to mobile terminal 20 (#8). As a result, a floor plan is displayed on the display unit of mobile terminal 20 or predetermined computer 43, as shown in Fig. 5, for example, on which mark M indicating the current location of the mobile phone owner and mark F indicating the location where the fire has occurred are marked, and the mobile phone owner can know his or her own location and the location where the fire has occurred. The location information server 40 may not necessarily be triggered by the transmission of location information (ID) when transmitting the map information with ignition points to the mobile terminal 20, but may also transmit a request to the location information server 40 in response to an operation of the mobile terminal 20 or periodically, and transmit the map information with ignition points in response to the request.

[0039] Next, a display layout change function (first feature), which is a function unique to the mobile terminal 20 constituting the location information system of this embodiment, that is, the display format of app icons on the home screen, will be described using the display screen example shown in Figure 3. The first feature, the icon display layout change function, changes the layout of the home screen as shown in FIGS. 3(A) to 3(C) depending on the usage environment of the mobile terminal 20.

[0040] As a specific example, the mobile terminal 20 itself determines whether the user (mobile terminal owner) is engaged in private or business activities, or whether a fire has broken out, and changes the home screen layout to a private mode (A), a business mode (B), or an emergency mode (C) according to the respective situations, as shown in Figures 3(A) to 3(C). Note that in Figure 3(B), the "flame" mark f displayed in the upper left corner of the screen is an icon of a location information display application as a user application with a fire alarm function that is launched when the functions of the location information system of the above embodiment are used on the mobile terminal 20.

[0041] For example, when the control unit of mobile terminal 20 receives a beacon signal that constitutes a location information system, it determines that the mobile terminal owner is engaged in business activities and can change the home screen layout to business mode. Also, even if a beacon signal is received, if it is outside of working hours and the terminal is located in an exceptional area such as an entrance or break room outside the workplace, it can determine that the mobile terminal owner is engaged in private activities and change the home screen layout to private mode. Also, icons that are no longer displayed on the screen due to the mode change can be displayed by swiping the screen.

[0042] Figure 3(A) shows an example of a home screen layout in private mode, Figure 3(B) shows an example of a home screen layout in business mode, and Figure 3(C) shows an example of a home screen layout in emergency mode. The private mode home screen in Figure 3(A) displays many icons for hobby-related apps such as games a and videos b, while the business mode screen in Figure 3(B) displays many icons for apps often used in business, such as schedule management, calculations c, and online meetings d. The location display app icon f is displayed in the upper left corner of the business mode home screen, which is relatively difficult to operate with a finger. In Figure 3(C), which shows the emergency mode screen, the location display app icon f and icons for apps often used in emergency mode, such as phone and email, are displayed in a location that is easy to operate with a finger (for example, the bottom right of the screen).

[0043] Furthermore, on the business mode home screen of Fig. 3(B), launching or operating a specific app such as a location information display app requires two steps: tapping the corresponding icon or button and then checking the pop-up display. On the emergency mode home screen of Fig. 3(C), however, a specific process can be executed with just one tap of the corresponding icon or button. This configuration eliminates unnecessary operations, allowing for quick input of instructions when needed, and also reduces the risk of erroneous operations or false alarms during normal times when there is no emergency.

[0044] Furthermore, in normal business mode, if the contact displayed or connected when the phone icon is tapped is "boss," the contact may be switched to a disaster prevention center in emergency mode. Furthermore, depending on the business / private situation, the contact may be changed to home or family, or the disaster prevention center contact may be changed to a head office / branch office based on location information and time information of the mobile terminal 20. This configuration enables prompt contact with the appropriate contact in an emergency. Furthermore, in business mode, restrictions may be placed on the launch of certain apps, such as game apps and music apps. In addition, in private mode, restrictions may be placed on the launch of certain apps, such as tools for contacting employees.

[0045] Next, a function (second feature) of changing the display mode of an icon of a specific application on the home screen, which is a function unique to the mobile terminal 20 constituting the position information system of this embodiment, will be described using an example display screen shown in FIG. The second feature is the ability to change the icon display mode. Under normal circumstances (peacetime), the home screen is displayed in a layout such as that shown in Figure 3(B), but when a specified event such as a fire occurs, the display mode is changed to that shown in Figures 4(A) to (C).

[0046] Of these, the specific example in Figure 4(A) is one in which the occurrence of an event is used as a trigger to change the background color of icon A with a "flame" mark and highlight the icon, the specific example in Figure 4(B) is one in which the occurrence of an event is used as a trigger to increase the contact reaction range of icon A, and the specific example in Figure 4(C) is one in which the occurrence of an event is used as a trigger to increase the size of icon A with a "flame" mark. By configuring in this way, it becomes possible to intuitively grasp the position of icons and quickly operate them for apps that are not often used. As another specific example, a home screen that is displayed in a layout such as that shown in Figure 3(B) may be triggered by the occurrence of an event to move the display position of the "flame" mark icon from the upper left corner of the screen, which is relatively difficult to operate, to the lower right corner, which is relatively easier to operate, or the "flame" mark A icon may not be displayed on the home screen under normal circumstances, but may be displayed on the home screen when an event occurs.

[0047] Next, a function (third feature) that changes the display mode of a specific button such as an emergency call button (SOS button) on the execution screen of a specific application (here, a location information display application), which is a function unique to the mobile terminal 20 that constitutes the location information system of this embodiment, will be described using example display screens shown in Figures 5 to 7. The third feature is the function to change the display mode of a specific button. Under normal circumstances (peacetime), the emergency call button (SOS button) B, which is displayed at the top of the screen as shown in Figure 5, changes to the display mode as shown in Figure 6 or Figure 7 when a specified event such as a fire occurs.

[0048] Of these, the specific example in Figure 6(A) is one in which the occurrence of an event is used as a trigger to change the background color of the SOS button B and highlight the icon, the specific example in Figure 6(B) is one in which the occurrence of an event is used as a trigger to increase the contact response range of the SOS button B, and the specific example in Figure 7(A) is one in which the occurrence of an event is used as a trigger to increase the size of the SOS button B. As another specific example, the SOS button B that was displayed at the top of the screen as shown in Figure 5 could be moved from the upper left corner of the screen, where it is relatively difficult to operate, to the lower right corner, where it is relatively easy to operate, as shown in Figure 7(B), or the SOS button B could be hidden on the home screen under normal circumstances, but displayed on the home screen when an event occurs.

[0049] Fig. 8 shows an example of a procedure in which the control unit of mobile terminal 20 changes the display layout of the home screen, which is the first feature described above. It is assumed that the location information display app is running when the process of Fig. 8 starts. When the control unit of mobile terminal 20 starts the process shown in Fig. 8, it first sets the display layout of the home screen to a private mode layout as shown in Fig. 3(A) (step S1). Next, it determines whether a predetermined event such as a fire has occurred (step S2), and if it determines that an event has occurred (Yes), it proceeds to step S3 and changes the display layout of the home screen to an emergency mode layout as shown in Figs. 4(A) to (C).

[0050] Next, it is determined whether the event state has ended (step S4), and if it is determined that the event state has ended (Yes), the process proceeds to step S5. Also, if it is determined in step S2 that the event has not occurred (No), the process proceeds to step S5. In step S5, it is determined whether a signal from a beacon within the monitoring area of ​​the location information system has been received. If it is determined that a beacon signal has not been received (No), the process returns to step S1 and repeats the above process. On the other hand, if it is determined in step S5 that a beacon signal has been received (Yes), the process proceeds to step S6, where it is determined whether the current time is within a preset business time slot. If it is determined that it is within a business time slot (Yes), the process proceeds to step S8, where the display layout of the home screen is changed to a business mode layout as shown in FIG. 3(B), and the process returns to step S2.

[0051] Furthermore, if it is determined in step S6 that the current time is not within working hours (No), the process proceeds to step S7, where it is determined whether the current location of the mobile terminal 20 is in a preset exception area such as an entrance or break room, and if it is determined that it is not in an exception area (No), the process proceeds to step S8, where the display layout of the home screen is changed to a business mode layout as shown in Fig. 3(B), and then the process returns to step S2. On the other hand, if it is determined in step S7 that the current location of the mobile terminal 20 is in an exception area (Yes), the process returns to step S1, and the display layout of the home screen is changed to a private mode layout as shown in Fig. 3(A).

[0052] Therefore, the control unit of the mobile terminal 20 that executes the process of Figure 8 has a function as a means for changing the display mode of the home screen, and this function is realized by cooperation between the microprocessor that constitutes the control unit and the program in the memory unit. 8 is merely an example, and the procedure is not limited to that shown in the flowchart. For example, it may be possible to determine whether a predetermined event has occurred in the first step after starting the process.

[0053] While the present invention has been described above based on the embodiments, it is not limited to the above embodiments and can be modified as appropriate without departing from the spirit of the invention. For example, in the above embodiments, a push notification is sent when a fire (emergency) occurs, but received fire information does not necessarily have to be displayed or notified as a push notification. Furthermore, even if a message is not displayed on the display unit, it may be possible to visually recognize that an event (emergency) has occurred by changing the icon of a location information display app.

[0054] Furthermore, in the above embodiment, the occurrence of an event (emergency) such as a fire was described as a trigger for switching the display format of the emergency call button (SOS button) on the screen. However, instead of the occurrence of an event, a change in the location or time of the owner of the information terminal device may be used as a trigger for switching the display format of the emergency call button (SOS button) on the screen or the contacts to be displayed.

[0055] Furthermore, in the above embodiment, the present invention has been described as being applied to a location information system and an information terminal device (smartphone) used therein, but it can also be applied to a system that does not have a location information server 40 and transmits and displays the occurrence of a fire to an information terminal device based on information from the fire information server 80. Furthermore, in the above embodiment, the case where a location information system is used has been described, but it may also be applied to a system that uses an entrance / exit management system that manages which room (area) or facility a person holding an entrance pass is in.

[0056] Furthermore, as a method for determining the condition within the monitored area, it is possible not only to collect detection data from sensors such as detectors, but also to import the results of analyzing the collected data from a terminal and determine the condition. In the above embodiment, a system has been described that has a function of notifying an information terminal device when a fire is detected as an example of an emergency, but it is also possible to configure the system as an outdoor disaster monitoring system that notifies an information terminal device when a disaster such as an earthquake or flood occurs. In this case, GPS information acquired by the mobile terminal may be used as location information. [Explanation of symbols]
