  By the way, in an apartment house where a dwelling unit controller is connected in a crossover manner as shown in FIG. 3, a fire has occurred in a dwelling unit, and the dwelling unit controller installed in that dwelling unit has burned. If the communication line 120 connected to the burned dwelling unit controller is short-circuited, all of the emergency call control unit 40 and the dwelling unit controllers 60, 80, 100 connected to the crossover wiring type cannot communicate. There was a problem of becoming. This will be described with reference to the drawings.

  In the dwelling unit monitoring system 10 described with reference to FIG. 4, when a fire occurs in a certain dwelling unit and the dwelling unit controller 100 of the dwelling unit burns, one of the communication lines 120 to which the burned dwelling unit control unit 100 is connected. The part may burn and the end point 380 and the end point 400 of the communication line 120 may be short-circuited. In this case, the current mainly flows through the short-circuited portion, so that all communications of the emergency call controller 40 and the dwelling unit controllers 60, 80, 100 are disabled. Thus, when the dwelling unit controllers 60, 80, 100 of each dwelling unit are connected in a crossover manner, when a fire occurs in a certain dwelling unit, not only the dwelling unit controller installed in the dwelling unit where the fire has occurred. In other dwelling unit controllers, there is a problem that a communication failure may occur.

  The present invention has been made to solve such a problem, and when a monitoring device and a dwelling unit controller installed in a plurality of dwelling units are connected in a wiring manner, a fire may occur in a certain dwelling unit. When it occurs, avoid all communication between the monitoring device and the dwelling unit controller from being disabled, and enable communication between the monitoring unit and the dwelling unit controller that has lost communication. With the goal.

  In order to solve the above-described problems, in the present invention, in a dwelling unit monitoring system in which a plurality of dwelling unit controllers and monitoring devices are connected by crossover wiring, a communication failure detection unit of the dwelling unit controller is connected to the monitoring device. When the occurrence of a communication failure is detected, it is connected upstream from the dwelling unit controller at the location of the fire (the direction in which the device is connected in the crossover wiring to the dwelling unit controller of the unit where the fire occurred) The wiring cutting part of the dwelling unit controller cuts the wiring between the adjacent dwelling unit controller connected by the crossover wiring. In addition, when it is detected that the supply of power has been stopped due to the disconnection of the wiring, the wireless terminal driven by the power supply other than the transition wiring shifts to a state in which communication with the monitoring device is possible using a wireless signal. .

  According to the present invention configured as described above, when the occurrence of a communication failure with the monitoring device is detected by the dwelling unit controller, the dwelling unit connected in the upstream direction from the dwelling unit controller at the fire occurrence location. In the controller, the wiring between the adjacent dwelling unit controller is cut. As a result, even if the communication unit connected to the burned dwelling unit controller is short-circuited due to the burning of the dwelling unit control unit installed in the fired dwelling unit, the effect of the short circuit (communication failure Generation) can be prevented from reaching the dwelling unit controller connected in the upstream direction from where the wiring is cut. In addition, in the dwelling unit controller in which the communication by the crossover wiring and the supply of power are stopped due to the cutting of the wiring, the communication by the wireless terminal supplied with the power by the battery becomes possible. As a result, even if the communication unit connected to the burned dwelling unit controller is short-circuited due to the burning of the dwelling unit control unit installed in the fired dwelling unit, the effect of the short circuit (communication failure Generation) can be prevented from reaching the dwelling unit controller connected in the downstream direction from where the wiring is cut. Therefore, when a monitoring device and a dwelling unit controller installed in a plurality of dwelling units are connected in a crossover manner, when a fire occurs in a certain dwelling unit, all communication between the monitoring unit and the dwelling unit control unit becomes impossible. You can avoid that. In addition, even a dwelling unit controller that has become unable to communicate due to disconnection of wiring can communicate with the monitoring device.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a functional configuration example of a dwelling unit monitoring system 500 according to the present embodiment. In FIG. 1, the dwelling unit monitoring system 500 according to the present embodiment includes an emergency call master unit 520, an emergency call control unit 540 (corresponding to the monitoring device in the claims), and dwelling unit controllers 560, 580, and 600.

  Here, a communication failure has occurred in the dwelling unit controller 560 when the dwelling unit controller 580 that has detected the occurrence of a fire has burned, and the communication line 860 connected thereto is short-circuited. Therefore, a communication failure has occurred in the dwelling unit controller 580 as well. However, since the disconnection information is not stored in the internal memory 910 of the dwelling unit controller 580, the switch SW2 is not switched from on to off. Similarly, a communication failure has occurred in the dwelling unit controller 600. However, since the disconnection information is not stored in the internal memory 910 of the dwelling unit controller 600, the switch SW3 is not switched from on to off.

  As described above, when the physical wiring connection between the dwelling unit controller 560 and the dwelling unit controller 580 is disconnected, the CPU (power stop detection unit 940) of the dwelling unit controller 580 supplies power to the dwelling unit controller 580. Detects that has stopped. The wireless terminal 950 that has received the detection result shifts to a state in which communication using a wireless signal is possible with the emergency call controller 540. Then, the resident in the dwelling unit can call or call a manager who is around the emergency call master 520 using the wireless terminal 950.

  Next, a cutting operation example of the dwelling unit controller 580 in the dwelling unit monitoring system 500 will be described. If the CPU 880 (fire detection unit 620) of the dwelling unit controller 600 detects the occurrence of a fire, the communication circuit 900 (fire occurrence information transmission unit 640) of the dwelling unit controller 600 transmits the fire occurrence information to the emergency call controller. To 540. Next, the communication circuit 900 (disconnection information receiving unit 660) of the dwell unit controller 580 connected in the upstream direction from the dwell unit controller 600 disconnects the physical wiring connection with the dwell unit controller 600 to be disconnected. The cutting information indicating the necessity to do is received from the emergency call controller 540. Next, the CPU 880 (storage control unit 680) of the dwelling unit controller 580 stores the disconnection information received by the communication circuit 900 (disconnection information reception unit 660) in the internal memory 910 (disconnection information storage unit 700).

  Thereafter, when the CPU 880 (communication failure detection unit 720) of the dwelling unit controller 580 detects the occurrence of a communication failure with the emergency call control unit 540, the CPU 880 (wiring disconnection unit 740) of the dwelling unit control unit 580 stores in the internal memory 910. By confirming that the cutting information is stored and switching the switch SW2 from on to off, the physical wiring connection with the dwelling unit controller 600 to be cut is cut off.

  Here, the communication failure has occurred in the dwelling unit controller 580 when the dwelling unit controller 600 that detects the occurrence of a fire burns, and the communication line 860 connected thereto is short-circuited. Therefore, a communication failure has also occurred in the dwelling unit controller 600. However, since the disconnection information is not stored in the internal memory 910 of the dwelling unit controller 600, the switch SW3 is not switched from on to off. Similarly, a communication failure has occurred in the dwelling unit controller 560. However, since the disconnection information is not stored in the internal memory 910 of the dwelling unit controller 560, the switch SW1 is not switched from on to off.

  As described above, when the physical wiring connection between the dwelling unit controller 580 and the dwelling unit controller 600 is disconnected, the CPU (power stop detection unit 940) of the dwelling unit controller 600 supplies power to the dwelling unit controller 600. Detects that has stopped. The wireless terminal 950 that has received the detection result shifts to a state in which communication using a wireless signal is possible with the emergency call controller 540. Then, the resident in the dwelling unit can call or call a manager who is around the emergency call master 520 using the wireless terminal 950.

  As described above in detail, according to the present embodiment, when a fire occurs in a certain dwelling unit and the communication line 860 is short-circuited, the dwell unit controller that detects the occurrence of the fire and the 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.

  Further, in the dwelling unit controller in which communication via the communication line 860 and supply of power are stopped due to the disconnection of the physical wiring connection, the wireless terminal 950 driven by a power source other than the transition wiring is in a state in which communication by a wireless signal is possible And migrate. For this reason, 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 downstream direction including the dwelling unit controller that has detected the occurrence of the fire. Can do. 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. In addition, even a dwelling unit controller that has become unable to communicate due to disconnection of wiring can communicate with the emergency call controller 540.

  In the present embodiment described above, the disconnection information is generated by the emergency call controller 540 and transmitted to each dwelling unit controller by the disconnection information transmission unit 800, but is not limited thereto. For example, the cutting information may be generated by each dwelling unit controller.

  Moreover, although embodiment mentioned above demonstrated the structure by which the emergency call controller 540 and the three dwelling unit controllers 560, 580, 600 are connected by a crossover wiring type, it is not limited to this. For example, the emergency call controller 540 and four or more dwelling unit controllers may be connected in a crossover manner.

  In the above-described embodiment, the example in which the switches SW1, SW2, and SW3 are provided on the internal wirings branched at the end points 920, 940, and 960 in FIG. The switches SW1, SW2 and SW3 may be provided on the internal wiring before the operation.

  Moreover, although embodiment mentioned above demonstrated the example which performs a cutting | disconnection operation | movement with the dwelling unit controller connected in the one upstream direction with respect to the dwelling unit controller which detected generation | occurrence | production of fire, it is not limited to this. For example, the cutting operation may be performed by two or more dwelling unit controllers connected in the upstream direction.

  In the above-described embodiment, the wireless terminal 950 is accommodated in the dwelling unit controller, but is not limited thereto. For example, as long as it is installed in a dwelling unit, it may be configured to operate independently. In this case, by making the connection with the power stop detection unit 940 wireless, the degree of freedom increases due to the arrangement of the wireless terminal 950.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly.
