1. Embodiment A disaster prevention support system 1 according to an 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 a disaster prevention support system 1 connected to this disaster prevention system 2.

The disaster prevention system 2 shown in the figure includes an R-type fire receiver 21 installed at the disaster prevention center of the fire prevention object, and various disaster prevention equipment installed at various locations of the fire prevention object and connected to the fire receiver 21. Be prepared. Specifically, the disaster prevention equipment includes a smoke detector 22, a transmitter 23, a fire door 24, a fire shutter 25, an alarm valve 26 for sprinkler equipment, an emergency telephone base unit 27, an emergency telephone slave unit 28, and a repeater 29. . The actual number of disaster prevention equipment will be determined depending on the size of the fire prevention target. Among these disaster prevention equipment, the smoke detector 22 measures the surrounding smoke concentration and transmits an analog value indicating the measured smoke concentration to the fire receiver 21 . The transmitter 23 transmits a transmitter signal to the fire receiver 21 when the transmitter is operated. The fire door 24 and the fire shutter 25 are connected to the fire receiver 21 via a repeater 29. The repeater 29 controls the opening and closing of the fire door 24 or the fire shutter 25 upon receiving the activation signal from the fire receiver 21, and transmits a response signal to the fire receiver 21 when the fire door 24 or the fire shutter 25 is activated. . The alarm valve 26 is connected to the fire receiver 21 via a repeater 29, and when the alarm valve 26 detects running water, the repeater 29 transmits a running water detection signal to the fire receiver 21. The emergency telephone base unit 28 is connected to the fire receiver 21 via the emergency telephone base unit 27, and when the emergency telephone base unit 28 is operated, the emergency telephone base unit 27 transmits an emergency telephone fire signal to the fire receiver 21. Send.

The fire receiver 21 connected to these disaster prevention equipment sends and receives signals to and from each disaster prevention equipment using a polling/selecting method, and when it detects the occurrence of an event, it sends event information that notifies the content and location of the event that has occurred. is sent to the disaster prevention support system 1. These events include cautions, detector alarms, fire outbreaks, transmitter operations, emergency telephone operations, and alarm valve activations. Among these events, a caution is determined to have occurred when the smoke density measured by the smoke detector 22 exceeds 3%/m and its duration (accumulation time) exceeds 5 seconds. The sensor alarm is determined to have occurred when the smoke density measured by the smoke detector 22 exceeds 10%/m, and when the duration (accumulation time) exceeds 40 seconds. A fire occurs when a certain period of time has elapsed after a detector alarm, when multiple smoke detectors 22 are triggered, when a transmitter signal is received from the transmitter 23, or when a fire receiver When a fire confirmation operation is performed in step 21, it is determined that a fire has occurred. A transmitter operation is determined to have occurred when a transmitter signal is received from the transmitter 23. When an emergency telephone fire signal is received from the emergency telephone base unit 27, it is determined that the emergency telephone operation has occurred. The alarm valve activation is determined to have occurred when a flowing water detection signal is received from the repeater 29 connected to the alarm valve 26.

Next, the disaster prevention support system 1 includes a support server 11 for supporting the self-defense fire brigade working in fire prevention areas, a terminal 12 carried by each member of the self-defense fire brigade, and a support server 11, the terminal 12, and the A communication line 13 for communicably connecting the receiver 21 is provided. The communication line 13 is a communication network such as the Internet or a wireless LAN.

Specifically, the support server 11 supports the activities of the self-defense fire brigade by making it possible to view the layout of disaster prevention equipment within the fire prevention target. For this purpose, the support server 11 stores layer data for each terminal 12 that is used to create the equipment layout diagram. This layer data is layer data that specifies the position of each display element constituting the equipment layout diagram using a coordinate system. When this layer data is updated, the support server 11 transmits a synchronization request as a push notification to the target terminal 12, and synchronizes the layer data stored in the terminal 12. This layer data will be described later. Further, upon receiving event information from the fire receiver 21, the support server 11 transfers the received event information to the terminal 12 as a push notification.

Specifically, the terminal 12 is a mobile terminal such as a smartphone, a mobile phone, a tablet terminal, or a wearable terminal. FIG. 2 is a block diagram showing the configuration of this terminal 12.

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

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

Among these functions, when event information is received from the support server 11, the event information acquisition unit 1211 records the event information in an event history table stored in the storage unit 122. Specifically, the date and time of the event, its contents, and the identification information of the disaster prevention equipment that started the event are recorded.

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

Among the layers shown in the figure, the frame layer (base layer) is a layer that illustrates the frame of the fire prevention object. Specifically, it is a layer illustrating the positions of pillars, walls, and floors of the fire prevention object. In this layer, the locations of stairs, toilets, evacuation exits (emergency exits), and AEDs of fire prevention objects are also illustrated using icons. This skeleton layer cannot be displayed/hidden by a user's operation.

The viewing restricted area layer (mask layer) is a layer for hiding part or all of the area where viewing is restricted in the frame of the fire prevention object. In this layer, viewing restricted areas are filled with a single color. This restricted viewing area layer is higher than the skeleton layer, but lower than the other layers. Therefore, display elements of other layers are not hidden by the restricted viewing area. For example, the icon of the smoke detector 22 or the warning area will not be hidden by the restricted viewing area, which will prevent the location of the fire from becoming unknown. This viewing restricted area layer cannot be switched between display and non-display by a user's operation.

Note that the presence or absence of this viewing restricted area layer and the area where viewing is restricted in this layer differ depending on the user of the terminal 12. For example, if a tenant on the third floor of a fire prevention property does not want tenants on other floors to know the building block diagram of the floor, the support server 11 provides the tenant on the third floor with a viewing restricted area layer that hides the building block on the third floor. On the other hand, tenants on other floors will be provided with a viewing restricted area layer that hides the building blocks on the third floor from the support server 11. Note that personnel at the disaster prevention center are not provided with the viewing restricted area layer for any floor, and can view the building blocks of all floors.

The caution area layer is a layer that illustrates a caution area set for a fire prevention object. A caution zone layer is prepared for each caution zone, and in this layer, a blinking frame line indicating the caution zone is displayed. The color of the frame line is orange in the alert state, and red after the sensor is activated. Further, the opacity of the frame line is displayed at 100% in the first report, and is displayed at 50% after the second report. This warning zone layer cannot be displayed/hidden by user operations.

Note that this warning area layer is mainly used when the fire receiver 21 is a P-type receiver and the specific position of the activated smoke detector 22 cannot be specified. If the fire receiver 21 is an R-type receiver and the specific location of the activated smoke detector 22 can be specified, it does not necessarily have to be used.

The equipment layer is a layer that uses icons to illustrate the positions of disaster prevention equipment of the fire prevention target. Equipment layers are prepared for each type of disaster prevention equipment, and specifically, a transmitter/emergency telephone layer, a fire prevention/smoke exhaust equipment layer, a fire extinguishing equipment layer, and an evacuation equipment layer are prepared.

In the transmitter/emergency telephone layer, the positions of the transmitter 23 and the emergency telephone handset 28 are illustrated using icons. This transmitter/emergency telephone layer can be switched between display and non-display by the user's operation.

In the fire prevention/smoke exhaust equipment layer, the positions of fire prevention equipment and smoke exhaust equipment are illustrated using icons. Here, the fire prevention equipment includes the fire door 24 and the fire shutter 25, and the smoke exhaust equipment includes a damper, a smoke exhaust machine, a smoke exhaust window, and the like. This fire prevention/smoke exhaust equipment layer can be switched between display and non-display by user's operation.

In the fire extinguishing equipment layer, the positions of fire extinguishers and fire hydrants are illustrated using icons. This fire extinguishing equipment layer can be displayed/hidden by a user's operation.

In the evacuation equipment layer, the positions of evacuation equipment such as evacuation ladders and slow descent planes are illustrated using icons. This evacuation equipment layer can be switched between display and non-display by the user's operation.

The operating equipment layer uses animation icons to illustrate the positions of activated smoke detectors 22 and alarm valves 26 and the positions of operated transmitters 23 and emergency telephone handsets 28 among the disaster prevention equipment of the fire prevention target. This is a layer that Since the positions of disaster prevention equipment that are not activated or operated are not shown in this activated equipment layer, activated or operated disaster prevention equipment will not be buried in such disaster prevention equipment. The icon of each disaster prevention facility is, for example, a GIF image that is displayed for reference in association with the coordinate position on the layer, and is not subject to enlarged display or reduced display. Therefore, the display size of the icon of each disaster prevention equipment is constant regardless of whether the equipment layout is enlarged or reduced. This operating equipment layer cannot be switched between display and non-display by a user's operation.

Among the disaster prevention equipment illustrated in the operating equipment layer, the icon color of the smoke detector 22 is displayed in orange in the caution state, and in red after the sensor is activated. Further, the opacity of the icon is displayed at 100% in the first report, and is displayed at 50% after the second report. The icon animation is an animation of ripples that spread radially. The position of the smoke detector 22 that has issued the alarm in this way is red and has movement, and the expanding movement makes it very noticeable. On the other hand, the icons of the alarm valve 26, the transmitter 23, and the emergency telephone handset 28 are blinking icons. The icons of the transmitter 23 and the emergency telephone handset 28 are displayed regardless of whether the transmitter/emergency telephone layer is displayed or not. Even when the transmitter/emergency telephone layer is hidden, the user can recognize the positions of the icons of the operated transmitter 23 and emergency telephone handset 28.
The above is an explanation of the layer structure of the equipment layout diagram.

When the map creation unit 1212 creates an equipment layout diagram, the display control unit 1213 causes the display unit 123 to display a floor map screen including the created equipment layout diagram. FIG. 4 is a diagram showing an example of a floor map screen displayed on the display unit 123.

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

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 diagram 31 for the floor that the user of the terminal 12 is in charge of is displayed, and when the display floor switching button 32B is selected, the equipment layout diagram 31 for the fire floor is displayed. Ru. That is, the equipment layout diagram 31 is displayed so as to be switchable on a floor-by-floor basis. In the initial state, the display floor switching button 32B is selected. Note that information on the floor that the user of the terminal 12 is in charge of and information on the role that the user plays are stored in the storage unit 122 of the terminal 12.

The display/non-display switching buttons 33A to 33D are toggle buttons that are operated to switch between displaying and non-displaying disaster prevention equipment icons. The initial state is off. 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 equipment layout diagram 31. Conversely, when switched to the off state, the fire extinguishing equipment layer is hidden and the icons of the fire extinguisher and fire hydrant disappear from the equipment 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 evacuation equipment layer becomes the display target, and the icons of the fire prevention equipment and smoke evacuation equipment are displayed on the equipment layout diagram 31. be done. Conversely, when switched to the off state, the fire prevention and smoke evacuation equipment layer is hidden, and the icons of the fire prevention equipment and smoke evacuation equipment disappear from the equipment 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 he or she wishes to refer to on the equipment layout diagram 31. For example, if the user belongs to the initial fire extinguishing team, use a fire extinguisher and fire hydrant, if the user belongs to the reporting and communication team, use the transmitter 23 and emergency telephone handset 28, and if the user belongs to the safety protection team, use the fire prevention equipment. If the equipment and smoke exhaust equipment belong to the evacuation guidance team, only the evacuation equipment can be displayed on the equipment layout diagram 31. Therefore, it is possible to avoid a situation where the disaster prevention equipment that the user wants to refer to gets mixed up with other types of disaster prevention equipment. This effect is particularly noticeable in mobile terminals with small screens.

The display/non-display switching buttons 33A to 33D display icons and type names of disaster prevention equipment, and function as legends for the icons. Further, the appearance of the display/non-display switching buttons 33A to 33D changes depending on the selection state thereof. Specifically, in the off state, the button is displayed as a white background, and in the on state, it is displayed as a hatched button. This is to enable the user to determine which disaster prevention equipment icon is to be displayed just by looking at the display/non-display switching buttons 33A to 33D.

FIG. 5 is a diagram showing, as an example, a floor map screen displayed when the display/non-display switching button 33D is switched to the on state on the floor map screen shown in FIG. On the floor map screen shown in the same figure, as a result of operating the display/hide switching button 33D and switching it to the on state, the fire protection/smoke exhaust equipment layer becomes the display target, and the icon S2 of the smoke exhaust equipment is changed to the equipment layout diagram 31. Displayed. Further, on the same screen, as a result of the display/non-display switching button 33D being switched to the on state, the appearance of the button is changed from a white background to a shaded area.

FIG. 6 is a diagram showing, as another example, a floor map screen displayed when the display floor switching button 32A is selected on the floor map screen shown in FIG. On the floor map screen shown in the figure, as a result of the display floor being switched from the fire floor to the floor in charge, the equipment layout diagram 31 of the floor the user is in charge of is displayed instead of the equipment layout diagram 31 of the fire floor. However, the selection states of the display/non-display switching buttons 33A to 33D displayed on the same screen are maintained as they were when the equipment layout diagram 31 of the fire floor was displayed. Therefore, on the floor map screen shown in the figure, the icon S2 of the smoke exhaust equipment is displayed in the equipment layout diagram 31. By maintaining the selected state of the display/hide switching buttons 33A to 33D regardless of the change in the displayed floor, the user can select the display/hide switching buttons 33A to 33D each time the displayed floor is changed. No need to fix it. Note that even when the displayed floor is switched from the assigned floor to the fire floor, the selection states of the display/non-display switching buttons 33A to 33D are maintained.

The equipment layout diagram 31 constituting the floor map screen can be displayed in an enlarged or reduced size according to a user's operation. However, regardless of whether the equipment layout diagram 31 is enlarged or reduced, the display size of the icon of the smoke detector 22 is maintained constant. This is because if the icon of the smoke detector 22 is enlarged along with the enlargement of the equipment layout diagram 31, other display elements will be hidden by the enlarged icon. Further, if the icon of the smoke detector 22 is reduced along with the reduction of the equipment layout diagram 31, the icon becomes difficult to see and the source of the fire becomes difficult to identify. FIG. 7 is an example of an enlarged diagram of the equipment layout diagram 31, and FIG. 8 is an example of a reduced diagram of the equipment layout diagram 31. The icon S1 of the smoke detector 22 shown in these figures has a constant display size compared to FIG. 4 and the like. Enlarging or reducing the image of the equipment layout diagram 31 targets the images of the building frame layer, restricted viewing area layer, restricted area layer, and equipment layer, and does not target the image of the operating equipment layer, so the smoke detector 22 The display size of the icon S1 is maintained constant. Note that the display size of the icon is not limited to the icon S1 of the smoke detector 22, but as long as it is a disaster prevention equipment illustrated in the operating equipment layer, the display size of the icon is maintained constant regardless of whether the equipment layout diagram 31 is enlarged or reduced.

2. Modifications The above embodiment may be modified as follows. The following variants may be combined with each other.

2-1. Modification example 1
The types of sensors constituting the disaster prevention system 2 are not limited to smoke detectors. A heat detector or flame detector may be used instead of a smoke detector.

2-2. Modification example 2
The criteria for determining caution and sensor alarm are not limited to the above example. The smoke concentration and accumulation time thresholds that serve as determination criteria may be set as appropriate depending on the installation status of the smoke detector 22. However, the threshold for attention is lower than the threshold for sensor alarm.

2-3. Modification example 3
Although the number of equipment layers is "4" in the above embodiment, 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, and display/non-display may be switched separately. Similarly, the fire protection/smoke exhaust equipment layer may be divided into a fire prevention equipment layer and a smoke exhaust equipment layer, and the fire extinguishing equipment layer may be divided into a fire extinguisher layer and a fire hydrant layer, and the display/non-display may be switched separately. As another example, the system may further include an emergency supplies layer in which the locations of emergency supplies such as an AED, a stretcher, and a first aid kit are illustrated using icons. This first aid supplies layer may be switchable between display and non-display by a user's operation.

2-4. Modification example 4
The icon shown in the equipment layer is an example of a symbol indicating disaster prevention equipment. Disaster prevention equipment does not necessarily have to be expressed using pictograms.

2-5. Modification example 5
In the warning area layer and the operating equipment layer, the caution state and the state after a sensor alarm are distinguished by the difference in the color of the frame line or icon, but these states can be distinguished by differences in display formats other than color. You may also do so. For example, these states may be distinguished by differences in shape, size, or animation. Similarly, the states after the first report and the second report may be distinguished by a difference in display mode other than the opacity of the frame line or icon.

2-6. Modification example 6
In the operating equipment layer, by displaying the icon blinking, it is expressed that the transmitter 23 or the emergency telephone handset 28 has been operated, but it is indicated that these disaster prevention equipment have been operated by display modes other than the blinking display. You may also try to express that. For example, the shape, size, or animation of the icon may be changed from normal times to indicate that these disaster prevention equipment have been operated. Similarly, the activation of the alarm valve 26 may be expressed by a display mode other than a blinking display.

2-7. Modification example 7
The operation for switching the display/hide of the equipment layer is not limited to the on/off operation of a toggle button. For example, display/non-display of the equipment layer may be switched by turning on/off a check box.

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

2-9. Modification 9
In the activated equipment layer, the activated fire door 24 or fire prevention shutter 25 may be displayed blinking. Furthermore, in addition to the activated fire door 24 or fire prevention shutter 25, the operated equipment layer may also display an operated fire extinguisher, fire hydrant, or evacuation appliance.

2-10. Modification 10
The above specification of maintaining the display size of the icon of the smoke detector 22 (disaster prevention equipment illustrated in the operating equipment layer) constant regardless of the scaling of the equipment layout diagram 31 is separate from the overlay display method. May be adopted. That is, it may be adopted in a display method different from the overlay method.

2-11. Modification 11
The above-mentioned specification of superimposing the icon of the smoke detector 22 on the viewing restricted area (mask area) may be adopted separately from the overlay display method. That is, it may be adopted in a display method different from the overlay method.

2-12. Modification example 12
Layers other than the equipment layer may also be switched between display and non-display by user operations.

2-13. Modification example 13
The viewing restricted area layer may be configured such that display/non-display cannot be switched during normal times, but display/non-display can be switched after an event occurs. In other words, it may be possible to cancel viewing restrictions after an event occurs. For example, by canceling viewing restrictions in the event of a fire, self-defense fire fighters can efficiently carry out self-defense firefighting activities.

2-14. Modification example 14
In each embodiment, the map creation means and display control means of the present invention are applied to display on the terminal 12 of the disaster prevention support system 1 or the display device installed in the disaster prevention center, but automatic fire alarm equipment It may be used to display a map on the fire receiver panel of a fire receiver, or it may be used in a display device such as a general operation panel that displays a map based on information from the fire receiver.

2-15. Modification example 15
The appearance and arrangement of the display/non-display 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 users 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, display modes such as color, shape, size, pictograph design, blinking cycle, etc. may be changed between the on state and the off state. In this case as well, only a part of the button may be changed instead of the entire button.

2-16. Modification example 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 display floor may be switchable by tab selection.

2-17. Modification example 17
When the blinking icon of the transmitter 23 or the emergency telephone handset 28 is displayed on the floor map screen, the display/non-display switching button 33 on the same screen may also be displayed blinking. By flashing the display/non-display switching button 33, the user can know the operating status of the disaster prevention equipment by looking at the button.

2-18. Modification example 18
In the above embodiment, all of the floor map screen display/hide switching buttons 33A to 33D are turned off in the initial state, but specific buttons can be turned on depending on the role played by the user. You may also leave it there. For example, if the user belongs to the initial fire extinguishing team, turn on the display/hide switch button 33A to display fire extinguishers and fire hydrants in advance, and if the user belongs to the report liaison team, display/hide. The non-display switching button 33B may be turned on to display the transmitter 23 and the emergency telephone handset 28 in advance. By doing so, the user does not need to select the display/non-display switching button 33. In this case, the display control unit 1213 identifies a button corresponding to the user's role by, for example, referring to a table that associates the role of the self-defense fire brigade with a specific button, and turns the identified button on in the initial state. Set.

2-19. Modification example 19
Depending on the floor of the fire prevention property, certain types of disaster prevention equipment may not exist. Regarding such a floor, when displaying it on the floor map screen, the display/hide switching button 33 corresponding to the non-existing disaster prevention equipment may be made unselectable. Specifically, display of the display/non-display switching button 33 may be omitted. Alternatively, it may be displayed in a manner that the user can determine that the disaster prevention equipment icon is not displayed even if the icon is selected. Specifically, it may be grayed out. In this way, by linking the display method of the display/hide switching button 33 with the presence or absence of disaster prevention equipment, the user can judge the presence or absence of disaster prevention equipment just by looking at the display/hide switching 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.

2-20. Modification example 20
The functions provided in the support server 11 may be provided in the fire receiver 21 or the general operation panel. That is, the layer data may be stored in the fire receiver 21 or the general operation panel, and the data may be synchronized with the terminal 12. Further, event information may be transmitted to the terminal 12.

2-21. Modification example 21
In the above embodiment, all of the floor map screen display/hide switching buttons 33A to 33D are turned off in the initial state, but all buttons are set to be turned on in the initial state. Good too. When the floor map screen including the equipment layout diagram 31 for each floor such as the fire floor is displayed, all disaster prevention equipment icons are displayed in the initial state without turning on the display/hide switching buttons 33A to 33D. Therefore, for example, a user who is not familiar with the operation will not mistakenly judge that there is no disaster prevention equipment on each floor such as the fire floor.

2-22. Modification 22
In addition, on the floor map screen that has the equipment layout diagram 31 and display/hide switch buttons 33A to 33D, an operation to erase the display/hide switch buttons 33A to 33D (for example, scroll down at the bottom of the screen to display/hide When the operation of deleting the switching buttons 33A to 33D is performed, the display/hide switching buttons 33A to 33D are deleted on the floor map screen, and the area of the equipment layout diagram 31 is expanded and displayed. In this state, if an operation is performed to redisplay the display/hide switching buttons 33A to 33D (for example, an operation to redisplay the display/hide switching buttons 33A to 33D by scrolling up at the bottom of the screen), the display/hide switching buttons 33A to 33D are redisplayed. The switching buttons 33A to 33D may be redisplayed and the original floor map screen may be redisplayed. Then, when the area of the equipment layout diagram 31 is expanded and displayed, the equipment layout diagram 31 may be displayed in an enlarged manner.

2-23. Modification 23
In the above embodiment, it has been explained that in the event of a fire, a floor map screen including the equipment layout diagram 31 for the floor in question is displayed, but even in normal times, the floor map screen for each floor such as the floor in charge can be displayed by menu operation The screen can be displayed. Here, the initial on/off states of the display/non-display switching buttons 33A to 33D on the floor map screen may be set to be different during a fire and during normal times. Alternatively, it may be possible to set the settings for each terminal 12 according to the user's request.
