The fire occurrence information receiving unit 820 of the emergency call master 520 receives the fire occurrence information transmitted from the fire occurrence information sending unit 780 of the emergency call control unit 540. Next, based on the fire occurrence information received by the fire occurrence information receiving unit 820, the notifying unit 840 of the emergency call master device 520 notifies information indicating the dwelling unit where the fire occurred, the date and time, and the like (step S160).

  Next, the disconnection information transmission unit 800 of the emergency call controller 540 is connected to the dwell unit control that is connected upstream by the dwell unit controller 600 specified by the fire occurrence information received by the fire occurrence information reception unit 760. The cutting information is transmitted to the machine 580 (step S180). The disconnect information receiving unit 660 of the dwell unit controller 580 receives the disconnect information addressed to itself transmitted from the emergency call controller 540. Next, the storage control unit 680 of the dwelling unit controller 580 stores the cutting information received by the cutting information receiving unit 660 as being addressed to itself in the cutting information storage unit 700 (step S200). After the process in step S200 ends, the process in the dwelling unit monitoring system 500 ends.

  FIG. 4 is a flowchart illustrating an example of an operation performed by each dwelling unit controller of the dwelling unit monitoring system 500 illustrated in FIG. 3 at regular time intervals regardless of whether or not a fire has occurred in the dwelling unit. The process of step S220 in FIG. 4 starts when a signal indicating a request for detecting a communication failure is input from the CPU 880 (wiring cutting unit 740) to the communication circuit 900 (communication failure detection unit 720).

  First, the communication failure detection unit 720 determines whether or not a communication failure has occurred with the emergency call controller 540 (step S220). If communication failure detection unit 720 determines that no communication failure has occurred (NO in step S220), the processing in step S220 is repeated. On the other hand, when communication failure detection unit 720 determines that a communication failure has occurred (YES in step S220), wiring cutting unit 740 determines whether or not cutting information is stored in cutting information storage unit 700. (Step S240).

  If the wiring cutting unit 740 determines that cutting information is not stored in the cutting information storage unit 700 (NO in step S240), the wiring cutting unit 740 does nothing. Thereby, the process in the dwelling unit monitoring system 500 is complete | finished. On the other hand, when the wiring cutting unit 740 determines that the cutting information is stored in the cutting information storage unit 700 (YES in step S240), the wiring cutting unit 740 is physically connected to the dwelling unit controller to be cut. The wiring connection is disconnected (step S260). After the cutting process in step S260 ends, the process in the dwelling unit monitoring system 500 ends.

  In addition, when a fire has occurred in the dwelling unit in which the dwelling unit controller 600 described in FIG. 4 is installed and the communication line 860 is short-circuited thereafter, in step S220, the communication failure detection unit 720 of each dwelling unit controller. The occurrence of a communication failure is detected by. In step S240, only the dwelling unit controller 580 (connected one upstream from the dwelling unit controller 600) whose cutting information is stored in the cutting information storage unit 700 (internal memory 910) turns on the switch SW2. By switching from to OFF, the physical wiring connection with the dwelling unit controller 600 to be disconnected is disconnected. However, since the disconnection information is not stored in the disconnection information storage unit 700 (internal memory 910) of the dwelling unit controller 560, the dwelling unit controller 560 does not switch the switch SW1 from on to off.

  As described above in detail, in the first embodiment, when a fire occurs in a certain dwelling unit and the communication line 860 is short-circuited, the dwell unit controller that has detected the occurrence of the fire and one connected upstream of it are connected. The physical wiring connection with the existing dwelling unit controller is disconnected. For this reason, it is possible to prevent the influence of the short circuit of the communication line 860 due to the occurrence of a fire (occurrence of communication failure) from reaching the dwelling unit controller connected in the upstream direction from the dwelling unit controller that has detected the occurrence of the fire. Can do. Therefore, in the dwelling unit monitoring system 500 in which the emergency call controller 540 and the plurality of dwelling unit controllers 560, 580, 600 are connected in a crossover manner, all of the emergency call control unit 540 and the dwelling unit controllers 560, 580, 600 are connected. It can be avoided that communication becomes impossible.

  For example, when a fire occurs in the dwelling unit in which the dwelling unit controller 600 is installed and the communication line 860 is short-circuited, the dwelling unit controller 600 that detects the occurrence of the fire and the dwelling unit control unit that is connected upstream by one. Since the physical wiring connection with 580 is disconnected, the influence of the short circuit of the communication line 860 due to the occurrence of a fire (occurrence of communication failure) is connected in the upstream direction from the dwelling unit controller 600 that detected the occurrence of the fire. It is possible to prevent the dwelling unit control units 560 and 580 from reaching.

  In addition, when a fire occurs in the dwelling unit in which the dwelling unit controller 580 is installed and the communication line 860 is short-circuited, the dwelling unit control unit 580 that has detected the occurrence of the fire and a dwelling unit control unit that is connected upstream by one. Since the physical wiring connection with 560 is cut off, the influence of the short circuit of the communication line 860 due to the occurrence of a fire (occurrence of communication failure) is connected upstream from the dwelling unit controller 580 that detected the occurrence of the fire. It is possible to prevent reaching the dwelling unit controller 560. Therefore, it is possible to avoid that all communications of the emergency call controller 540 and the dwelling unit controllers 560, 580, 600 are disabled.

  Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a block diagram illustrating a functional configuration example of the dwelling unit monitoring system 500 according to the second embodiment. In FIG. 5, those given the same reference numerals as those shown in FIG. 1 have the same functions, and therefore redundant description is omitted here.

  In the second embodiment, the dwell unit controllers 560, 580, 600 in the dwell unit monitoring system 500 include a fire occurrence information transmission unit 640 ′ instead of the fire occurrence information transmission unit 640 of FIG. Further, the dwelling unit controllers 560, 580, and 600 include a fire occurrence information receiving unit 670 and a cutting information generating unit 675 instead of the cutting information receiving unit 660 of FIG. Moreover, the dwelling unit controllers 560, 580, and 600 include a storage control unit 680 ′ instead of the storage control unit 680 of FIG. Note that the emergency call controller 540 does not include the disconnection information transmission unit 800 of FIG.

  The fire occurrence information transmission unit 640 ′, when the fire detection unit 620 of the own dwelling unit controller detects the occurrence of a fire in the dwelling unit, transmits the fire occurrence information to notify the occurrence of the fire in the dwelling unit. The process which transmits to the dwelling unit controller connected to the one upstream direction or the emergency call controller 540 is performed. Also, the fire occurrence information transmission unit 640 ′ not only transmits the fire occurrence information by itself when it detects a fire occurrence in its own dwelling unit controller, but also forwards the fire occurrence information sent from the downstream direction in the upstream direction. The process to do is also performed.

  For example, the fire occurrence information transmission unit 640 ′ of the dwelling unit controller 600 performs a process of transmitting the fire occurrence information to the dwelling unit controller 580 that is connected one upstream from the own dwelling unit controller 600. In addition, the fire occurrence information transmission unit 640 ′ of the dwelling unit controller 580 performs a process of transmitting (or transferring) the fire occurrence information to the dwelling unit control unit 560 that is connected one upstream from the own dwelling unit control unit 580. . The fire occurrence information transmission unit 640 ′ of the dwelling unit controller 560 transmits (or forwards) the fire occurrence information to the emergency call control unit 540 that is connected one upstream from the own dwelling unit control unit 560.

  The fire occurrence information receiving unit 670 receives fire occurrence information transmitted from the dwelling unit controller connected in the downstream direction. When the fire occurrence information receiving unit 670 receives fire occurrence information from one downstream dwelling unit controller, the fire occurrence information receiving unit 670 supplies the fire occurrence information to the fire occurrence information transmitting unit 640 '. In response to this, the fire occurrence information transmitting unit 640 ′ transfers the fire occurrence information passed from the fire occurrence information receiving unit 670 to the dwell unit controller or emergency call controller 540 connected one upstream.

  When the fire occurrence information receiving unit 670 receives the fire occurrence information from the downstream dwell unit controller, the fire occurrence information receiving unit 670 determines whether one dwell unit controller connected in the downstream direction belongs to the fire occurrence place. Only in the case, a cutting information generation request is supplied to the cutting information generation unit 675. In order to make this determination, the fire occurrence information receiving unit 670 has a connection relationship table that represents the connection relationship in the transition wiring of each dwelling unit controller 560, 580, 600. This connection relation table shows, for example, the order of arrangement of each dwelling unit controller 560, 580, 600 on the transition wiring by dwelling unit controller ID information. Further, this connection relation table includes information indicating which ID is own. The fire occurrence information receiving unit 670 confirms the fire occurrence dwell unit controller ID information included in the connection relation table and the fire occurrence information sent from the downstream side, so that a dwell unit controller one downstream from itself fires. It is possible to determine whether the place belongs (whether you are one upstream from the fire place).

  When the disconnection information generation unit 675 receives a disconnection information generation request from the fire occurrence information reception unit 670, the disconnection information generation unit 675 indicates a disconnection indicating the necessity of disconnecting the physical wiring connection with the dwelling unit controller connected in the downstream direction. Information (same as the cutting information of the first embodiment) is generated.

  In the second embodiment, when the disconnection information generation unit 675 of the dwelling unit controller 560 receives a disconnection information generation request from the fire occurrence information reception unit 670, the disconnection information generation unit 675 is connected to the dwelling unit controller 580 that is connected one downstream direction. Cutting information indicating the necessity of cutting the physical wiring connection is generated. In addition, when the disconnection information generation unit 675 of the dwelling unit controller 580 receives a disconnection information generation request from the fire occurrence information reception unit 670, a physical wiring connection with the dwelling unit control unit 580 connected in the downstream direction is performed. The cutting information indicating the necessity of cutting is generated. Note that the disconnection information generation unit 675 of the dwelling unit controller 600 connected to the end of the crossover wiring does not receive a disconnection information generation request from the fire occurrence information reception unit 670, and therefore does not generate disconnection information.

  When the cutting information is generated by the cutting information generation unit 670, the storage control unit 680 ′ stores the cutting information in the cutting information storage unit 700. In the second embodiment, when the cutting information is generated by the cutting information generation unit 670, the storage control unit 580 ′ of the dwell unit controllers 560 and 580 stores the cutting information in the cutting information storage unit 700. Note that the storage control unit 580 ′ of the dwelling unit controller 600 does not cause the cutting information generation unit 670 to generate cutting information, and therefore does not store the cutting information in the cutting information storage unit 700.
