  It is known that not only fire doors but also general room doors can be greatly suppressed by closing smoke when a fire occurs. However, in the case of a general room door, unlike the fire door, it is necessary for the person in the building to close it manually. The doors that people who evacuate from a room pass in the event of a fire are often left open because they quickly pass, and if the door of the room is the source of the fire, smoke will spread widely.

  The present invention has been made in view of such circumstances, and an object of the present invention is to ensure the safety of people in the building by closing an effective door for suppressing smoke diffusion.

  In order to solve the above problems, the disaster prevention system according to the present invention, when a fire occurs in the building, should be closed based on the fire point specifying means for specifying the fire point and the specified fire point. A door specifying unit that specifies the door of the room and a notification unit that prompts the person in the building to close the specified door are provided.

  In a preferred aspect, the door specifying means specifies a door on a route from the specified fire point to the evacuation opening or the pit section as the door of the room to be closed.

  In a further preferred aspect, the notification means prompts the person in the building to close the door by operating a warning device installed near the specified door.

  In a further preferred aspect, the notifying unit notifies the terminal carried by the person in the building of the specified door.

  In a further preferred aspect, the terminal illustrates a position of the specified door on a plan view of the building.

  According to the disaster prevention support system of the present invention, it is possible to ensure the safety of people in the building by closing the door that is effective for suppressing the diffusion of smoke.

This icon S1 is an animation icon of a ripple that spreads radially. The icon S2 is an icon indicating the door of the room to be closed. In this way, in the equipment layout diagram, the position of the door of the room to be closed is shown on the plan view of the building, so that the user can refer to this equipment layout map to easily locate the door to be closed. You can figure it out.

  The display control unit 73 displays the screen generated by the screen generation unit 72 on the display.

1-2. Operation Next, the operation of the disaster prevention system 1 when a fire occurs will be described with reference to the sequence diagram shown in FIG.

  When the fire determination unit 51 of the fire receiver 5 determines that a fire has occurred in the building (step Sa1), the fire point identification unit 52 of the fire receiver 5 identifies the fire point by referring to the equipment table ( Step Sa2). When the fire point is specified, the fire notification unit 53 of the fire receiver 5 notifies the specified fire point and also transmits a fire occurrence signal notifying that a fire has occurred to the support server 6 (step Sa3).

  When the fire notification signal is received from the fire receiver 5, the fire notification unit 61 of the support server 6 notifies the fire point specified by the fire receiver 5 and pushes fire information for notifying the fire occurrence. To each terminal 7 (step Sa4).

  If the disaster prevention support program is not activated in the terminal 7 that has received the fire information, the program is activated (step Sa5). After starting the program, the screen generation unit 72 of the terminal 7 generates a fire notification screen, and the display control unit 73 of the terminal 7 causes the generated fire notification screen to be displayed on the display (step Sa6). This fire notification screen is a screen for notifying the occurrence of a fire and a fire point and confirming whether or not to participate in the self-defense fire fighting activity, and a participation button and a non-participation button are displayed on this screen. When any one of the displayed buttons is selected (step Sa7), participation availability information corresponding to the selected button is transmitted to the support server 6 (step Sa8). In the support server 6 that has received the participation permission information, the participation information is updated based on the received participation permission information (step Sa9). After updating the participation information, the synchronization unit 65 of the support server 6 synchronizes the participation information stored in the terminal 7 with the updated participation information (step Sa10).

  After transmitting the fire information, the door identification unit 62 of the support server 6 refers to the door table and, based on the fire point identified by the fire receiver 5, identifies the room to be closed in order to suppress smoke diffusion. The door is specified (step Sa11). When the door to be closed is specified, the door information is updated and the door ID of the newly specified door is added (step Sa12). After updating the door information, the synchronization unit 65 of the support server 6 synchronizes the door information stored in the terminal 7 with the updated door information (step Sa13). After the synchronization of the door information, when the resident in the terminal 7 instructs the floor map to be displayed (step Sa14), the screen generation unit 72 of the terminal 7 causes the floor map screen (Fig. 3)), and the display control unit 73 of the terminal 7 displays the generated floor map screen on the display (step Sa15). By referring to this floor map screen, the resident can recognize the door of the room to be closed.

After specifying the door to be closed, the warning device specifying unit 63 of the support server 6 refers to the warning device table and specifies the warning device 8 installed in the vicinity of the specified door (step Sa16). When the warning device 8 is specified, the warning device control unit 64 of the support server 6 transmits a start signal to the specified warning device 8 to operate it (step Sa17). Upon receiving the activation signal, the warning device 8 displays a warning and outputs a warning sound to prompt the person in the building to close the door installed near the device (step Sa18). In response to this prompt, the resident closes the door. The operation of the warning device 8 is continued until the stop signal transmitted from the support server 6 is received.
The above is the description of the operation of the disaster prevention system 1 when a fire occurs.

  According to the disaster prevention system 1 described above, the safety of the occupants can be ensured by closing the door effective for suppressing the diffusion of smoke. In particular, by prompting to close only the door installed on the evacuation route according to the fire point, it is possible to efficiently promote the closing of the door. In addition, since the door to be closed is displayed on the map on the terminal 7, the user can easily understand the position of the door to be closed. Furthermore, by urging the warning device 8 to close the door, it is possible to urge the person who does not carry the terminal 7 to close the door. However, even if it is possible to secure the safety of the evacuation route by closing the door, there is a possibility that smoke may diffuse from the floor directly above to the upper floor through an unexpected space from the fire floor. deep.

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

2-1. Modification 1
In the above embodiment, the synchronization notification transmitted from the support server 6 is used as a trigger to synchronize the support information between the support server 6 and the terminal 7. However, the synchronization request transmitted from the terminal 7 is used as a trigger. The synchronization may be performed. In that case, the terminal 7 periodically transmits a synchronization request to the support server 6. The synchronization request includes the file name and version information of each file of the support information stored in the terminal 7. The support server 6 that has received this synchronization request determines whether or not each file of the support information stored in the terminal 7 is the latest version, and if a file that is not the latest version is included, The file is notified to the terminal 7 as a synchronization target. Upon receiving this notification, the terminal 7 displays a confirmation screen for confirming the necessity of downloading the synchronization target file, and when the user instructs the download, the terminal 7 acquires the file from the support server 6.

2-2. Modification 2
The icon S2 illustrated in FIG. 3 is an example of a symbol indicating a door to be closed. The door to be closed does not necessarily have to be expressed using pictograms.

2-3. Modification 3
The position of the door to be closed need not necessarily be shown. Instead of the illustration, a character string indicating the position of the door to be closed may be displayed on the display of the terminal 7.

2-4. Modification 4
By limiting the synchronization target of the door information to only the terminal 7 of the person who is participating in the self-defense firefighting activity, the self-defense firefighters may be notified of the door to be closed. In particular, among self-defense firefighters, the evacuation guidance team and the safety protection team are notified of the door to be closed, and the evacuation guidance group closes the door necessary for evacuation along with evacuation guidance for the people in the building, The safety team may close the necessary doors as well as confirm smoke emission and the formation of fire protection compartments.

2-5. Modification 5
