  Next, the operation of the fire notification system 1 of the present embodiment will be described.

  FIG. 3 is a diagram for explaining a transmission path of information in the fire notification system 1 of the present embodiment. For example, when the power consumption information of the smart meter 20 of the house D is transmitted to the management server 10, the power consumption information of the smart meter 20 of the house D is a route that approaches the parent device 60, for example, the house D, the house B, the smart meter 20 in the house A is transmitted in the order of a bucket relay, and is transmitted from the smart meter 20 in the house A to the management server 10 via the parent device 60 and the network 50.

  On the contrary, when information is transmitted from the management server 10 to the smart meter 20 in the house D, the information is transmitted to the smart meter 20 in the house A or the house F via the network 50 and the parent device 60. It is transmitted like a bucket relay in the order of the smart meter 20 of F, house E, and house D.

  Next, a fire information transmission path will be described. For example, as shown in FIG. 3, it is assumed that a fire has occurred in a house C and the fire detector 30 installed in the house C has detected a fire. At this time, the fire detector 30 transmits fire information to the smart meter 20 in the house C. The smart meter 20 that has received the fire information cuts off the supply of electricity to the house C.

  Furthermore, the communication control part 26a controls the communication part 24, determines the smart meter 20 of the house which transmits fire information first, and transmits fire information. This fire information is relayed by the neighboring smart meter 20 in a multi-hop manner, and transmitted to the management server 10 via the parent device 60 and the network 50. For example, when the smart meter 20 in the house C transmits fire information to the smart meter 20 in the house B, the fire information is relayed to the base unit 60 by the smart meter 20 in the house A and is sent to the management server 10 via the network 50. Sent.

  In addition, the neighboring smart meter 20 that has received the fire information creates a display screen for notifying that a fire has occurred in the neighborhood, and displays the display screen on a display device connected to the home terminal 40, for example, the display of a personal computer. Is displayed. As a result, it is possible to notify neighboring residents that a fire has occurred in the neighborhood. In the above example, the residents of the houses A and B are notified that a fire has occurred in the neighborhood.

  In addition, when the management server 10 receives the fire information, the management server 10 obtains the address of the house where the fire has occurred from the unique information of the smart meter 20 that transmitted the fire information from the database, and the fire station 110 and the disaster prevention management company 112 Notify where it occurred. In addition, the management server 10 transmits an e-mail notifying that a fire has occurred in the neighborhood to the mobile terminal 100 owned by the residents of the house near the house where the fire has occurred.

  According to the present embodiment configured as described above, the fire information from the smart meter 20 of the house where the fire has occurred relays to the smart meter 20 of the neighboring house in a multi-hop manner, similar to the power consumption information. To the management server 10 on the electric power company side. For this reason, the electric power company may contact customers who live in the house where the fire occurred, contact the fire department 110, the police station, the disaster prevention management company 112, etc., or contact a house near the house where the fire occurred. It becomes possible to take measures such as. In addition, when fire information is included in the information received by the neighboring smart meter 20 by the multi-hop communication method, it is notified early through the home terminal 40 that a fire has occurred in the neighborhood. For this reason, neighboring residents can immediately know the occurrence of a fire in the neighborhood, and can quickly take action such as helping with fire fighting and evacuating. In addition, since the existing meter reading system using the smart meter 20 is used to notify the neighboring residents of the fire information, a system for notifying the neighboring residents of the fire information can be realized at a low cost.

  Further, according to the present embodiment, when the smart meter 20 of the house where the fire has occurred receives fire information from the fire detector 30, the power supply to the house is cut off. It becomes possible to cut off the supply. Thereby, it becomes possible for the fire department staff to shift to fire fighting activities immediately after arrival at the site, and it is possible to prevent the occurrence of a situation such as an electric shock when the fire department staff is conducting the fire fighting activities.

  In addition, according to the present embodiment, the power switching control unit 26c of the neighboring smart meter 20 receives the fire information from other smart meters 20 including the smart meter 20 where the fire has occurred by the multi-hop communication method. Shut off the power supply to For this reason, for example, when a nearby house spreads fire while a fire department member is performing a fire extinguishing activity, the fire department member can safely perform the fire extinguishing activity for the fire spreading.

  As mentioned above, although embodiment of this invention was described, embodiment of this invention is not restricted to what was mentioned above. For example, the neighboring smart meter 20 may activate the voice warning function of the fire detector 30 when fire information is transmitted in a multi-hop manner. In addition, when the fire information is transmitted by the multi-hop method, the neighboring smart meter 20 notifies the display device connected to the home terminal 40 (HEMS) that a fire has occurred in the neighborhood and to the house after a predetermined time. The power supply to the house may be cut off after transmitting the notice to cut off the power supply. Thereby, it is possible to prevent the power supply from being suddenly interrupted in a neighboring house.

  Further, according to the above-described embodiment, the transmission path of the fire information in the neighboring smart meter 20 is set in advance. Here, when the house where the fire has occurred is far from the parent device 60, the smart meter 20 that is not set as a fire information transmission path may be used for transmission of fire information by the multi-hop method. In this case, there may be a case where a resident of a house who cannot be said to be in the vicinity of the house where the fire has occurred is notified that a fire has occurred in the neighborhood.

  Therefore, when the smart meter 20 that is not set as a transmission path receives fire information, it informs that a fire has occurred in the neighborhood via the home terminal 40, shuts off the power supply to the house, and detects fire. The voice warning function of the device 30 may not be operated.

  Next, another embodiment will be described.

  In the example illustrated in FIG. 3, the residents of the house A and the house B are notified that a fire has occurred in the house C. However, it is desirable to notify all residents of the house A, the house B, the house D, the house E, and the house F that are located around the house C that the fire has occurred.

Therefore, according to another embodiment, a transmission path for fire information is set in advance, and the setting information is stored in the information storage unit 25. Then, the smart meter 20 of the house where the fire has occurred adds the information of the transmission path to the fire information and outputs the fire information. After the fire information passes through the preset transmission path, the plurality of smart meters 20 and It is transmitted to the management server 10 via the parent device 60. Specifically, in FIG. 3, for example, the fire information is set to be transmitted in the order of the house C, the house A, the house B, the house D, the house E, and the house F.
Thereby, the fact that a fire has occurred in the house C is notified to all neighboring residents by the home terminal 40 connected to the smart meter 20 of the neighboring house.

  In addition, according to the other embodiments described above, the fire information transmission path in the neighboring smart meter 20 is set in advance. It is also possible to notify the residents.

  Specifically, when the smart meter 20 receives fire information from the fire detector 30, the communication control unit 26 a transmits fire information for power company notification transmitted to the management server 10 as fire information and all neighboring smarts. Neighbor notification fire information to be transmitted to the meter 20 is created. And the communication control part 26a determines the smart meter 20 which transmits fire information similarly to the case where the used electric energy information is transmitted, and transmits the fire information for electric power company notification to the smart meter 20. Thereby, the electric power company report fire information is transmitted to the management server 10 by the multi-hop method. Next, the communication control unit 26a transmits the fire information for proximity notification to all the neighboring smart meters 20. The fire information for proximity notification is transmitted to the neighboring smart meter 20 by the same method as the command signal from the management server 10 is transmitted to the smart meter 20 designated by the management server 10 by the multi-hop method.

  Further, when the alarm control unit 26d of the neighboring smart meter 20 receives the fire information for power company notification, the alarm control unit 26d does not notify the neighborhood of the fire via the home terminal 40, and does not notify the neighborhood notification fire information. When received, control is performed to notify that a fire has occurred in the neighborhood via the home terminal 40. As a result, it is possible to notify all neighbors that a fire has occurred in the neighborhood.

  That is, in FIG. 3, when a fire occurs in the house C, the smart meter 20 in the house C creates fire information for power company reporting and fire information for neighborhood notification. Sends fire information for company reporting to notify the power company of the occurrence of a fire. At this time, in House A, it is not notified that a fire has occurred in the neighborhood. Next, fire information for neighborhood notification is transmitted to house A, house B, house D, house E, and house F. Thereby, the fact that a fire has occurred in the neighborhood of the home A, the home B, the home D, the home E, and the home F is notified.

  As a result, only residents in the vicinity of the house where the fire occurred will be notified that the fire has occurred in the neighborhood, and it will be possible to promptly take actions such as helping with fire fighting and evacuating. .
