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 on a fire prevention object and a disaster prevention support system 1 connected to this disaster prevention system 2. As shown in FIG.

The disaster prevention system 2 shown in FIG. Prepare. Specifically, as disaster prevention equipment, a smoke sensor 22, a transmitter 23, a fire door 24, a fire shutter 25, an alarm valve 26 for a sprinkler system, an emergency telephone main unit 27, an emergency telephone cordless handset 28, and a repeater 29 are provided. . The actual number of fire prevention equipment depends on the size of the fire protection object. Among these fire prevention equipment, the smoke detector 22 measures the smoke density in the surroundings and transmits an analog value indicating the measured smoke density 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 . This repeater 29 receives an operation signal from the fire receiver 21 and controls the opening and closing of the fire door 24 or the fire shutter 25, and when the fire door 24 or the fire shutter 25 operates, it transmits a response signal to the fire receiver 21. . 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 handset 28 is connected to the fire receiver 21 via the emergency telephone master set 27, and when the emergency telephone handset 28 is operated, the emergency telephone master set 27 transmits the emergency telephone fire signal to the fire receiver 21. Send.

The fire receiver 21 connected to these disaster prevention equipment transmits and receives signals to and from each disaster prevention equipment in a polling/selecting manner, and upon detecting the occurrence of an event, event information that notifies the details of the event that occurred and the place of occurrence. to the disaster prevention support system 1. This event includes caution, detector activation, fire occurrence, transmitter activation, emergency telephone activation, and alarm valve activation. Of these events, attention is determined to have occurred when the smoke concentration measured by the smoke detector 22 exceeds 3%/m and its duration (accumulation time) exceeds 5 seconds. A sensor alarm is cumulative when the smoke density measured by the smoke sensor 22 exceeds 10%/m, and is determined to have occurred when the duration (accumulation time) exceeds 40 seconds. A fire occurs when a certain period of time elapses after a sensor alarm is issued, when a sensor alarm is issued for a plurality of smoke sensors 22, when a transmitter signal is received from a transmitter 23, or when a fire receiver 21, when the fire confirmation operation is performed, it is determined that the 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 main unit 27, it is determined that an emergency telephone operation has occurred. Alarm valve actuation is determined to have occurred when a water flow detection signal is received from relay 29 connected to alarm valve 26 .

Next, the disaster prevention support system 1 includes a support server 11 for supporting a self-defense fire brigade operating at a fire prevention object, a terminal 12 carried by each member of the self-defense fire brigade, a support server 11, a terminal 12, and a fire and a communication line 13 for communicably connecting the receiver 21 . A 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 the disaster prevention equipment in the fire prevention object. Therefore, the support server 11 stores, for each terminal 12, layer data used to create an equipment layout plan. This layer data is layer data that designates the position of each display element that constitutes the facility layout using a coordinate system. When the layer data is updated, the support server 11 transmits a synchronization request as a push notification to the target terminal 12 to synchronize the layer data stored in the terminal 12 . This layer data will be described later. Further, when the event information is received from the fire receiver 21, the support server 11 transfers the received event information to the terminal 12 as a push notification.

The terminal 12 is specifically a mobile terminal such as a smart phone, a mobile phone, a tablet terminal, or a wearable terminal. FIG. 2 is a block diagram showing the configuration of this terminal 12. As shown in FIG.

The terminal 12 shown in FIG. A display unit 123 as a device, an operation input unit 124 as an input device such as an operation button or a touch panel, and a communication unit 125 as a communication interface for performing data communication with the support server 11 are provided.

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

The map creation unit 1212 creates a facility layout based on the layer data and event history table stored in the storage unit 122 . At that time, the map creating unit 1212 creates a facility layout by superimposing the layers indicated by the layer data. FIG. 3 is a diagram showing the layer structure of the facility layout plan created by the map creation unit 1212. As shown in FIG.

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

The view-restricted area layer (mask layer) is a layer for hiding part or all of the view-restricted area of the skeleton of the fire prevention object. This layer fills the restricted viewing area with a solid color. This view-restricted area layer is higher than the skeleton layer, but lower than the other layers. Therefore, the display elements of other layers are not hidden by the viewing restricted area. For example, the icon of the smoke sensor 22 and the warning area are not hidden by the viewing restricted area, and the location of the fire is not lost. This view-restricted area layer cannot be switched between display and non-display by the user's operation.

It should be noted that the presence or absence of this viewing-restricted area layer and the areas in which viewing is restricted in the layer differ depending on the user of the terminal 12 . For example, if the tenant on the 3rd floor of the fire prevention target does not want the skeleton of the floor to be known to the tenants on other floors, the tenant on the 3rd floor has a viewing restricted area layer that hides the skeleton of the 3rd floor. In contrast, the support server 11 provides the tenants on other floors with a view-restricted area layer that hides the skeleton of the third floor. It should be noted that personnel in the disaster prevention center are not provided with the view-restricted area layer of any floor, and can view the skeleton drawings of all floors.

The caution zone layer is a layer that illustrates the caution zone set for the fire prevention object. A caution area layer is prepared for each caution area, and in this layer, a frame line indicating the caution area is blinking. The color of the frame line is displayed in orange in the caution state, and displayed in red after the sensor is triggered. In addition, 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 area layer cannot be switched between display and non-display by the user's operation.

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 sensor 22 cannot be specified. If the fire receiver 21 is an R-type receiver and the specific position of the activated smoke detector 22 can be specified, it is not necessarily used.

The equipment layer is a layer that illustrates the position of the disaster prevention equipment of the fire prevention object using icons. A facility layer is prepared for each type of disaster prevention facility. Specifically, a transmitter/emergency telephone layer, a fire prevention/smoke exhaust facility layer, a fire extinguishing facility layer, and an evacuation device layer are prepared.

In the transmitter/emergency telephone layer, the positions of the transmitter 23 and the emergency telephone cordless 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 and smoke evacuation equipment layer, the location of fire prevention equipment and smoke evacuation equipment is illustrated using icons. Here, the fire prevention equipment is the fire door 24 and the fire shutter 25, and the smoke exhaust equipment is a damper, a smoke exhaust, a smoke exhaust window, and the like. This fire protection/smoke exhaust facility layer can be switched between display and non-display by the user's operation.

In the fire extinguisher layer, the locations of fire extinguishers and hydrants are illustrated using icons. The display/non-display of this fire extinguishing equipment layer can be switched by the user's operation.

In the evacuation equipment layer, the positions of evacuation equipment such as evacuation ladders and gentle descenders 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 show the positions of the activated smoke detector 22 and alarm valve 26 and the operated transmitter 23 and emergency telephone cordless handset 28 among the fire prevention equipment. layer. The active equipment layer does not show the locations of non-activated or non-operated equipment, so that such equipment does not obscure activated or operated equipment. The icon of each disaster prevention facility is, for example, a GIF image displayed 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 facility is constant regardless of whether the facility layout is enlarged or reduced. This operating facility layer cannot be switched between display and non-display by the user's operation.

The color of the icon of the smoke detector 22 among the disaster prevention equipment illustrated in the operating equipment layer is displayed in orange in the caution state, and displayed in red after the alarm is issued by the detector. Further, the opacity of the icon is displayed at 100% for the first report, and is displayed at 50% after the second report. The icon animation is an animation of radiating ripples. The position of the smoke sensor 22 that has issued the alarm in this way is red and has movement, and is conspicuous due to the expanding movement. On the other hand, the icons of the alarm valve 26, transmitter 23 and emergency telephone handset 28 are blinking icons. The icons of the transmitter 23 and the emergency telephone cordless handset 28 are displayed regardless of whether the transmitter/emergency telephone layer is displayed or not. The user can recognize the positions of the icons of the operated transmitter 23 and emergency telephone cordless handset 28 even when the transmitter/emergency telephone layer is hidden.
The above is the description of the layer structure of the facility layout plan.

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

The floor map screen shown in the figure has a facility layout diagram 31, display floor switching buttons 32A and 32B, and display/non-display switching buttons 33A to 33D. Among these display elements, 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 31 of the floor in charge of the user of the terminal 12 is displayed, and when the display floor switching button 32B is selected, the equipment layout 31 of the fire floor is displayed. be. The display/non-display switching buttons 33A to 33D are toggle buttons, and are operated to switch display/non-display of disaster prevention equipment. For example, when the display/hide switching button 33A is operated and switched to the OFF state, the fire extinguishing equipment layer is hidden, and the fire extinguisher and fire hydrant icons disappear from the equipment layout drawing 31 . Conversely, when switched to the ON state, the fire extinguishing equipment layer becomes a display target, and icons of fire extinguishers and fire hydrants are displayed in the equipment layout drawing 31 . As another example, when the display/hide switch button 33D is operated and switched to the OFF state, the fire prevention/smoke exhaust equipment layer is hidden, and the icons of the fire prevention equipment and the smoke exhaust equipment disappear from the equipment layout drawing 31. . Conversely, when switched to the ON state, the fire prevention/smoke exhaust equipment layer becomes a display target, and the icons of the fire prevention equipment and smoke exhaust equipment are displayed in the equipment layout drawing 31 . By operating these display/non-display switching buttons 33A to 33D, the user of the terminal 12 can display only the disaster prevention equipment that the user wants to refer to on the equipment layout drawing 31. FIG. For example, a fire extinguisher and a fire hydrant if the user belongs to the initial firefighting team, a transmitter 23 and an emergency telephone handset 28 if the user belongs to the report contact team, and a fire protection team if the user belongs to the safety protection team. Equipment and smoke exhaust equipment can be displayed on the equipment layout drawing 31 only for evacuation equipment when belonging to the evacuation guidance team.

The facility layout drawing 31 that constitutes the floor map screen can be enlarged and reduced according to the user's operation. However, regardless of whether the facility layout drawing 31 is enlarged or reduced, the display size of the icon of the smoke sensor 22 is maintained constant. This is because if the icon of the smoke sensor 22 is enlarged along with the enlargement of the facility layout drawing 31, other display elements will be hidden by the enlarged icon. Moreover, if the icon of the smoke sensor 22 is reduced together with the reduction of the facility layout drawing 31, the icon becomes difficult to see and the source of the fire becomes difficult to identify. 5 is an example of an enlarged view of the equipment layout drawing 31, and FIG. 6 is an example of a reduced view of the equipment layout drawing 31. As shown in FIG. The display size of the icon S of the smoke sensor 22 shown in these figures is kept constant compared to FIG. Enlargement or reduction of the image of the facility layout drawing 31 targets the images of the skeleton layer, the viewing restricted area layer, the warning area layer, and the facility layer, and does not target the image of the operating facility layer, so the smoke detector 22 , the display size of the icon S is kept constant. It should be noted that the display size of the icon is kept constant regardless of whether the facility layout drawing 31 is enlarged or reduced, not only for the icon S of the smoke sensor 22, but also for the disaster prevention equipment illustrated in the operating equipment layer.
