[0011] 1. Embodiment A disaster prevention support system 1 according to one embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a block diagram showing the configuration of a disaster prevention system 2 installed in a fire prevention object and the disaster prevention support system 1 connected to this disaster prevention system 2.

[0012] The disaster prevention system 2 shown in the figure includes an R-type fire receiver 21 installed in the disaster prevention center of the fire prevention object, and various disaster prevention equipment installed at various locations in the fire prevention object and connected to the fire receiver 21. Specifically, the disaster prevention equipment includes smoke detectors 22, transmitters 23, fire doors 24, fire shutters 25, sprinkler alarm valves 26, emergency telephone base units 27, emergency telephone handsets 28, and repeaters 29. The actual number of disaster prevention equipment depends on the size of the fire prevention object. Of these disaster prevention equipment, the smoke detector 22 measures the surrounding smoke density and transmits an analog value indicating the measured smoke density to the fire receiver 21. When the transmitter 23 is operated, it transmits a transmitter signal to the fire receiver 21. The fire doors 24 and fire shutters 25 are connected to the fire receiver 21 via repeaters 29. This repeater 29 controls the opening and closing of the fire door 24 or the fire shutter 25 upon receiving an activation signal from the fire control panel 21, and when the fire door 24 or the fire shutter 25 is activated, it transmits a response signal to the fire control panel 21. The alarm valve 26 is connected to the fire control panel 21 via the repeater 29, and when the alarm valve 26 detects flowing water, the repeater 29 transmits a flowing water detection signal to the fire control panel 21. The emergency telephone handset 28 is connected to the fire control panel 21 via the emergency telephone base unit 27, and when the emergency telephone handset 28 is operated, the emergency telephone base unit 27 transmits an emergency telephone fire signal to the fire control panel 21.

[0013] The fire receiver 21 connected to these disaster prevention equipment transmits and receives signals to each disaster prevention equipment using a polling / selecting method. When an event is detected, the fire receiver 21 transmits event information to the disaster prevention support system 1, notifying the details and location of the event. These events include caution, detector alarm, fire occurrence, transmitter operation, emergency call operation, and alarm valve activation. Of these events, a caution is determined to have occurred when the smoke concentration measured by the smoke detector 22 exceeds 3% / m and continues for more than 5 seconds (accumulation time). A detector alarm is determined to have occurred when the smoke concentration measured by the smoke detector 22 exceeds 10% / m and continues for more than 40 seconds (accumulation time). A fire is determined to have occurred when a certain time has passed since the detector alarm, when detector alarms are activated for multiple smoke detectors 22, when a transmitter signal is received from the transmitter 23, or when a fire confirmation operation is performed on the fire receiver 21. A transmitter operation is determined to have occurred when a transmitter signal is received from the transmitter 23. An emergency telephone operation is determined to have occurred when an emergency telephone fire signal is received from the emergency telephone base unit 27. An alarm valve operation is determined to have occurred when a running water detection signal is received from the repeater 29 connected to the alarm valve 26.

[0014] Next, the disaster prevention support system 1 includes a support server 11 for supporting the private fire brigade operating at a fire prevention object, a terminal 12 carried by each member of the private fire brigade, and a communication line 13 for communicatively connecting the support server 11, the terminal 12, and the fire receiver 21. The communication line 13 is a communication network such as the Internet or a wireless LAN.

[0015] Specifically, the support server 11 supports the activities of the private fire brigade by enabling viewing of a layout diagram of disaster prevention equipment within a fire prevention object. To this end, the support server 11 stores, for each terminal 12, layer data used to create the equipment layout diagram. This layer data is data for a layer that specifies the position of each display element that makes up the equipment layout diagram using a coordinate system. When this layer data is updated, the support server 11 sends a synchronization request as a push notification to the corresponding terminal 12, thereby synchronizing the layer data stored in the terminal 12. This layer data will be described later. Furthermore, when the support server 11 receives event information from the fire receiver 21, it forwards the received event information to the terminal 12 as a push notification.

[0016] Specifically, the terminal 12 is a mobile terminal such as a smartphone, a mobile phone, a tablet terminal, a wearable terminal, etc. FIG.

[0017] The terminal 12 shown in the same figure includes a control unit 121 having an arithmetic processing unit such as a CPU and a volatile memory such as a RAM, a memory unit 122 which is a storage device such as a flash memory, a display unit 123 which is a display device such as a liquid crystal display or an organic EL display, an operation input unit 124 which is an input device such as an operation button or a touch panel, and a communication unit 125 which is a communication interface for performing data communication with the support server 11.

[0018] When the control unit 121 of this terminal 12 executes the disaster prevention support program stored in the storage unit 122, the functions of an event information acquisition unit 1211, a map creation unit 1212, and a display control unit 1213 are realized.

[0019] Among these functions, when the event information acquisition unit 1211 receives event information from the support server 11, it records the event information in an event history table stored in the storage unit 122. Specifically, it records the date and time of the event occurrence, the content, and the identification information of the disaster prevention equipment that was the source of the event.

[0020] The map creation unit 1212 creates an equipment layout diagram based on the layer data and event history table stored in the storage unit 122. This equipment layout diagram is a diagram illustrating the layout of disaster prevention equipment installed in a fire prevention object using icons. The map creation unit 1212 creates the equipment layout diagram by overlaying layers indicated by the layer data. Figure 3 is a diagram showing the layer structure of the equipment layout diagram created by the map creation unit 1212.

[0021] Among the layers shown in the figure, the structural body layer (base layer) is a layer that illustrates the structural body of the fire prevention object. Specifically, it is a layer that illustrates the positions of the pillars, walls, and floors of the fire prevention object. This layer also illustrates the positions of the stairs, toilets, escape exits (emergency exits), and AEDs of the fire prevention object using icons. This structural body layer cannot be switched on and off by the user.

[0022] The restricted viewing area layer (mask layer) is a layer used to hide some or all of the areas of the structure of a fire prevention object that are restricted from viewing. In this layer, the restricted viewing area is filled with a single color. This restricted viewing area layer is higher than the structure layer but lower than the other layers. Therefore, the display elements of other layers are not hidden by the restricted viewing area. For example, the icon of a smoke detector 22 or a warning area will not be hidden by the restricted viewing area, making it impossible to determine the location of a fire. This restricted viewing area layer cannot be switched on / off by user operation.

[0023] The presence or absence of this restricted viewing area layer and the areas in this layer that are restricted from viewing vary depending on the user of terminal 12. For example, if a tenant on the third floor of a fire prevention facility does not want tenants on other floors to know the structural drawings of that floor, the support server 11 will not provide the tenant on the third floor with a restricted viewing area layer that hides the structural drawings of the third floor, whereas the support server 11 will provide the tenants on other floors with a restricted viewing area layer that hides the structural drawings of the third floor. The personnel of the disaster prevention center will not be provided with the restricted viewing area layers of any floors, and will be able to view the structural drawings of all floors.

[0024] The alert area layer is a layer that illustrates the alert areas set for fire prevention objects. A alert area layer is prepared for each alert area, and on this layer, a blinking border indicating the alert area is displayed. The border color is displayed in orange when in a caution state, and in red after the detector has been activated. The opacity of the border is displayed at 100% for the first report, and at 50% after the second report. This alert area layer cannot be switched on / off by the user.

[0025] This alert area layer is mainly used when the fire receiver 21 is a P-type receiver and cannot identify the specific location of the activated smoke detector 22. It does not necessarily have to be used when the fire receiver 21 is an R-type receiver and can identify the specific location of the activated smoke detector 22.

[0026] The facility layer is a layer that uses icons to illustrate the location of fire prevention equipment for fire prevention objects. Facility layers are prepared for each type of fire prevention equipment, specifically, a transmitter / emergency telephone layer, a fire prevention / smoke exhaust equipment layer, a fire extinguishing equipment layer, and an evacuation equipment layer.

[0027] In the transmitter / emergency telephone layer, the locations of the transmitter 23 and the emergency telephone handset 28 are shown using icons. The transmitter / emergency telephone layer can be switched between display and non-display by the user's operation.

[0028] The fire and smoke exhaust equipment layer uses icons to show the locations of fire and smoke exhaust equipment. Here, fire protection equipment refers to fire doors 24 and fire shutters 25, and smoke exhaust equipment refers to dampers, smoke exhaust machines, smoke exhaust windows, etc. This fire and smoke exhaust equipment layer can be displayed or hidden by the user.

[0029] The fire extinguishing equipment layer shows the locations of fire extinguishers and fire hydrants using icons. This fire extinguishing equipment layer can be displayed or hidden by the user.

[0030] The evacuation equipment layer uses icons to show the locations of evacuation equipment such as evacuation ladders and descents. The user can choose to show or hide this evacuation equipment layer.

[0031] The activated equipment layer is a layer that uses animated icons to illustrate the locations of activated smoke detectors 22 and alarm valves 26, as well as the locations of activated transmitters 23 and emergency telephone handsets 28, among the fire prevention equipment of the fire prevention object. This activated equipment layer does not illustrate the locations of inactivated or inactive fire prevention equipment, so activated or active fire prevention equipment is not obscured by such fire prevention equipment. The icons for each fire prevention equipment are displayed as GIF images, for example, that correspond to coordinate positions on the layer, and are not subject to zooming in or out. Therefore, the display size of each fire prevention equipment icon remains constant regardless of whether the facility layout diagram is zoomed in or out. This activated equipment layer cannot be switched on or off by user operation.

[0032] Among the disaster prevention equipment illustrated in the activated equipment layer, the icon color of the smoke detector 22 is displayed in orange when in a warning state and in red after the detector has activated an alarm. The icon's opacity is displayed at 100% for the first alarm and at 50% for the second alarm. The icon is animated as a radial ripple. The location of the activated smoke detector 22 is red and dynamic, expanding to make it highly visible. Meanwhile, the icons of the alarm valve 26, transmitter 23, and emergency handset 28 are flashing icons. The icons of the transmitter 23 and emergency handset 28 are displayed regardless of whether the transmitter / emergency phone layer is displayed. Even if the transmitter / emergency phone layer is hidden, the user can recognize the location of the icons of the operated transmitter 23 and emergency handset 28. This concludes the explanation of the layer structure of the facility layout diagram.

[0033] When the map creation unit 1212 creates an equipment layout plan, the display control unit 1213 displays a floor map screen including the created equipment layout plan on the display unit 123. Fig. 4 is a diagram showing an example of the floor map screen displayed on the display unit 123.

[0034] The floor map screen shown in the figure has an equipment layout diagram 31, display floor switching buttons 32A and 32B, and display / hide switching buttons 33A to 33D. Of these display elements, the equipment layout diagram 31 is an equipment layout diagram of the fire floor, and an icon S1 of the smoke detector 22 is displayed.

[0035] The display floor switching buttons 32A and 32B are buttons for switching the floor to be displayed. When the display floor switching button 32A is selected, the equipment layout plan 31 of the floor for which the user of the terminal 12 is responsible is displayed, and when the display floor switching button 32B is selected, the equipment layout plan 31 of the fire floor is displayed. In other words, the equipment layout plan 31 is displayed so that it can be switched on a floor-by-floor basis. In the initial state, the display floor switching button 32B is selected. Note that information about the floor for which the user of the terminal 12 is responsible and information about the role played by that user are stored in the memory unit 122 of the terminal 12.

[0036] The display / hide switching buttons 33A to 33D are toggle buttons that are operated to switch between displaying and hiding icons of disaster prevention equipment. The initial state is the off state. For example, when the display / hide switching button 33A is operated and switched to the on state, the fire extinguishing equipment layer becomes the display target, and icons of fire extinguishers and fire hydrants are displayed on the facility layout diagram 31. Conversely, when switched to the off state, the fire extinguishing equipment layer becomes the display target, and icons of fire extinguishers and fire hydrants disappear from the facility layout diagram 31. As another example, when the display / hide switching button 33D is operated and switched to the on state, the fire prevention and smoke exhaust equipment layer becomes the display target, and icons of fire prevention equipment and smoke exhaust equipment are displayed on the facility layout diagram 31. Conversely, when switched to the off state, the fire prevention and smoke exhaust equipment layer becomes the display target, and icons of fire prevention equipment and smoke exhaust equipment disappear from the facility layout diagram 31. By operating these display / hide switching buttons 33A to 33D, the user of the terminal 12 can display only the disaster prevention equipment that the user wishes to view on the facility layout diagram 31. For example, if a user belongs to the initial firefighting team, fire extinguishers and fire hydrants can be displayed; if a user belongs to the reporting and communication team, transmitters 23 and emergency telephone handsets 28 can be displayed; if a user belongs to the safety protection team, fire protection equipment and smoke exhaust equipment can be displayed; and if a user belongs to the evacuation guidance team, only evacuation equipment can be displayed on the equipment layout diagram 31. This prevents the disaster prevention equipment that the user wants to refer to from being confused with other types of disaster prevention equipment. This effect is particularly noticeable on mobile devices with small screens.

[0037] The display / hide switch buttons 33A to 33D display the icons and type names of the disaster prevention equipment, and function as legends for the icons. The appearance of the display / hide switch buttons 33A to 33D changes depending on their selected state. Specifically, when they are off, they are displayed as white buttons, and when they are on, they are displayed as shaded buttons. This is to allow the user to determine which disaster prevention equipment icons are being displayed just by looking at the display / hide switch buttons 33A to 33D.

[0038] Fig. 5 shows, as an example, a floor map screen that is displayed when the display / hide switch button 33D is switched to the on state on the floor map screen shown in Fig. 4. On the floor map screen shown in the figure, as a result of the display / hide switch button 33D being operated and switched to the on state, the fire protection and smoke exhaust equipment layer becomes the display target, and the smoke exhaust equipment icon S2 is displayed on the equipment layout diagram 31. Also, on the same screen, as a result of the display / hide switch button 33D being switched to the on state, the appearance of the button changes from white to shaded.

[0039] FIG. 6 shows another example of a floor map screen that is displayed when the display floor switching button 32A is selected on the floor map screen shown in FIG. 5. As a result of switching the displayed floor from the fire floor to the assigned floor, the floor map screen shown in FIG. 6 displays the equipment layout plan 31 of the floor for which the user is responsible, instead of the equipment layout plan 31 of the fire floor. However, the selected states of the display / hide switching buttons 33A-33D displayed on the screen are maintained in the same state as when the equipment layout plan 31 of the fire floor was displayed. Therefore, the floor map screen shown in FIG. 6 displays the smoke exhaust equipment icon S2 on the equipment layout plan 31. By maintaining the selected states of the display / hide switching buttons 33A-33D regardless of whether the displayed floor is changed, the user does not need to reselect the display / hide switching buttons 33A-33D each time the displayed floor is changed. The selected states of the display / hide switching buttons 33A-33D are maintained even when the displayed floor is switched from the assigned floor to the fire floor.

[0040] The equipment layout diagram 31, which constitutes the floor map screen, can be enlarged or reduced in size according to user operations. However, regardless of whether the equipment layout diagram 31 is enlarged or reduced, the display size of the smoke detector 22 icon remains constant. This is because if the smoke detector 22 icon were enlarged as the equipment layout diagram 31 was enlarged, other display elements would be hidden by the enlarged icon. Furthermore, if the smoke detector 22 icon were reduced as the equipment layout diagram 31 was reduced, the icon would become difficult to see, making it difficult to identify the source of a fire. Figure 7 is an example of an enlarged view of the equipment layout diagram 31, and Figure 8 is an example of a reduced view of the equipment layout diagram 31. The icon S1 of the smoke detector 22 shown in these figures remains constant in display size compared to Figure 4 and other figures. The enlargement or reduction of the image of the equipment layout diagram 31 applies to the images of the building structure layer, the restricted area layer, the alert area layer, and the equipment layer, but not to the images of the activated equipment layer, so the display size of the smoke detector 22 icon S1 remains constant. It should be noted that the display size of the icon, not limited to the icon S1 of the smoke detector 22, but for any disaster prevention equipment shown in the operational equipment layer, is maintained constant regardless of whether the equipment layout diagram 31 is enlarged or reduced.

[0041] 2. Variations The above embodiment may be modified as follows: The following modifications may be combined with each other.

[0042] 2-1. Variation 1 The type of detector that constitutes the disaster prevention system 2 is not limited to a smoke detector. Instead of a smoke detector, a heat detector or a flame detector may be employed.

[0043] 2-2. Variation 2 The criteria for determining whether to issue a warning or activate a detector are not limited to the above examples. The thresholds of smoke density and accumulation time that serve as the criteria may be set appropriately depending on the installation conditions of the smoke detector 22. However, the threshold for issuing a warning must be lower than the threshold for activating a detector.

[0044] 2-3. Variation 3 The number of facility layers is "4" in the above embodiment, but it may be 3 or less or 5 or more. For example, the transmitter / emergency telephone layer may be divided into a transmitter layer and an emergency telephone layer, which can be switched between visible and hidden separately. Similarly, the fire protection / smoke exhaust facility layer may be divided into a fire protection facility layer and a smoke exhaust facility layer, and the fire extinguisher facility layer may be divided into a fire extinguisher layer and a fire hydrant layer, which can be switched between visible and hidden separately. As another example, a first aid equipment layer may be further provided, which illustrates the locations of first aid equipment such as AEDs, stretchers, and first aid kits using icons. This first aid equipment layer may be able to be switched between visible and hidden by a user's operation.

[0045] 2-4. Variation 4 The icons shown in the facility layer are examples of symbols that represent disaster prevention facilities. Disaster prevention facilities do not necessarily have to be represented using pictograms.

[0046] 2-5. Variation 5 In the alert area layer and the activated equipment layer, the caution state and the state after the detector has been activated are distinguished by differences in the color of the border or icon, but these states may also be distinguished by differences in display manner other than color. For example, these states may be distinguished by differences in shape, size, or animation. Similarly, the first report and the second report and subsequent states may be distinguished by differences in display manner other than the opacity of the border or icon.

[0047] 2-6. Variation 6 In the activated equipment layer, the operation of the transmitter 23 or the emergency telephone handset 28 is indicated by flashing an icon, but the operation of these disaster prevention equipment may be indicated by a display mode other than flashing. For example, the operation of these disaster prevention equipment may be indicated by changing the shape, size, or animation of the icon from its normal state. Similarly, the activation of the alarm valve 26 may be indicated by a display mode other than flashing.

[0048] 2-7. Variation 7 The operation for switching between displaying and hiding the facility layer is not limited to the on / off operation of a toggle button. For example, the displaying and hiding of the facility layer may be switched by the on / off operation of a check box.

[0049] 2-8. Variation 8 In the above embodiment, the terminal 12 creates the facility layout diagram, but the support server 11 may create the diagram instead of the terminal 12 and provide it to the terminal 12. That is, the support server 11 may have the function of the map creation unit 1212. In that case, the support server 11 may display a floor map screen not only on the terminal 12 but also on a display device installed in the disaster prevention center.

[0050] 2-9. Variation 9 The activated equipment layer may be configured to flash the activated fire doors 24 or fire shutters 25. In addition to the activated fire doors 24 or fire shutters 25, the activated equipment layer may also display operated fire extinguishers, fire hydrants, or evacuation equipment.

[0051] 2-10. Variation 10 The above-mentioned specification of maintaining a constant display size of the icon of the smoke detector 22 (disaster prevention equipment illustrated in the activated equipment layer) regardless of the zooming in or out of the equipment layout diagram 31 may be adopted separately from the overlay display method, i.e., may be adopted in a display method other than the overlay method.

[0052] 2-11. Variation 11 The above-described feature of superimposing the icon of the smoke detector 22 on the restricted viewing area (masked area) may be adopted separately from the overlay display method, i.e., may be adopted in a display method other than the overlay method.

[0053] 2-12. Variation 12 Layers other than the facility layer may also be configured to be able to be switched between visible and invisible by user operation.

[0054] 2-13. Variation 13 The restricted viewing area layer may be configured so that it cannot be switched between visible and hidden under normal circumstances, but may be switched between visible and hidden after an event occurs. In other words, the restriction on viewing may be lifted after the event occurs. For example, by lifting the restriction on viewing in the event of a fire, private firefighters can efficiently carry out their own firefighting activities.

[0055] 2-14. Variation 14 In each embodiment, the map creation means and display control means of the present invention have been described as being applied to display on the terminal 12 of the disaster prevention support system 1 or on a display device installed in a disaster prevention center, but they may also be used for map display on the fire receiver panel of an automatic fire alarm system, or on a display device such as a general control panel that displays a map based on information from the fire receiver.

[0056] 2-15. Variation 15 The appearance and arrangement of the display / hide switching buttons 33A to 33D displayed on the floor map screen are not limited to the example shown in FIG. 4 and the like. These may be changed as appropriate according to the needs of the user of the disaster prevention support system 1. For example, in the above embodiment, the pattern of the entire button is changed between the on state and the off state, but only a part of the pattern may be changed. Alternatively, instead of the pattern, the display mode such as color, shape, size, pictogram design, blinking cycle, etc. may be changed between the on state and the off state. In this case, too, only a part of the button may be changed, rather than the entire button.

[0057] 2-16. Variation 16 The operation for switching the displayed floor on the floor map screen is not limited to selecting the displayed floor switching button 32. For example, the displayed floor may be switched by selecting a tab.

[0058] 2-17. Variation 17 When a flashing icon of the transmitter 23 or the emergency telephone handset 28 is displayed on the floor map screen, the display / hide switch button 33 on the same screen may also be made to flash. By making the display / hide switch button 33 flash, the user can know the operating status of the disaster prevention equipment by looking at the button.

[0059] 2-18. Variation 18 In the above embodiment, all of the display / hide switching buttons 33A to 33D on the floor map screen are initially set to the off state. However, specific buttons may be set to the on state depending on the role of the user. For example, if the user belongs to the initial firefighting team, the display / hide switching button 33A may be set to the on state, causing the fire extinguisher and fire hydrant to be displayed in advance, and if the user belongs to the reporting and communication team, the display / hide switching button 33B may be set to the on state, causing the transmitter 23 and the emergency telephone handset 28 to be displayed in advance. In this way, the user does not need to select the display / hide switching button 33. In this case, the display control unit 1213 identifies the button corresponding to the user's role by referring to a table that associates the role of the private fire brigade with a specific button, and sets the identified button to the on state in the initial state.

[0060] 2-19. Variation 19 Some floors of a fire prevention facility may not have certain types of disaster prevention equipment. For such floors, when the floor is displayed on the floor map screen, the display / hide switch button 33 corresponding to the non-existent disaster prevention equipment may be made unselectable. Specifically, the display of the display / hide switch button 33 may be omitted. Alternatively, the display may be such that the user can tell that the icon for the disaster prevention equipment will not be displayed even if the button is selected. Specifically, the button may be grayed out. By linking the display method of the display / hide switch button 33 with the presence or absence of disaster prevention equipment in this way, the user can determine the presence or absence of disaster prevention equipment simply by looking at the display / hide switch button 33. In this case, the display control unit 1213 determines the presence or absence of disaster prevention equipment on the floor to be displayed, for example, by referring to the equipment layer of the floor to be displayed.

[0061] 2-20. Variation 20 The functions of the support server 11 may be provided in the fire receiver 21 or the general operation panel. That is, the fire receiver 21 or the general operation panel may store layer data and synchronize the data with the terminal 12. In addition, event information may be transmitted to the terminal 12.

[0062] 2-21. Variation 21 In the above embodiment, all of the display / hide switch buttons 33A to 33D on the floor map screen are set to the off state in the initial state, but all of the buttons may be set to the on state in the initial state. When a floor map screen including an equipment layout diagram 31 of each floor such as a fire floor is displayed, icons for all disaster prevention equipment are displayed in the initial state even if the display / hide switch buttons 33A to 33D are not turned on, so that, for example, a user unfamiliar with the operation will not mistakenly determine that there is no disaster prevention equipment on each floor such as a fire floor.

[0063] 2-22.
