Accordingly, since the operation of unlocking the auto door (not shown) separately connected is the same as the conventional one, the description thereof is omitted, and in this embodiment, an earthquake occurs, and the information is notified to the room master unit. The operation will be described in detail.

When an earthquake occurs, the external organization 7 notifies the earthquake information receiver 5 via the external network 6 that an earthquake has occurred, and information such as the epicenter and the seismic intensity is transmitted. In the earthquake information receiver 5, the seismic intensity and the earthquake arrival time (S wave arrival time) of the area where the earthquake information receiver 5 is located are calculated from the transmitted information, and the controller 2 of the collective housing intercom system is used as the earthquake information. Send to.

In the controller 2, the data is received by the controller CPU 26 via the second data IF 22. At this time, the signal sensor 25 confirms the usage status of the video transmission path and notifies the controller CPU 26 of the usage status. When the video transmission path is not used, the control unit CPU 26 controls the control unit 2 and the room base unit 3 to be notified of the earthquake information to form a video path using the video transmission path. At the same time, an earthquake information reception signal is transmitted from the controller CPU 26 to the living room base unit 3 via the third data IF 23, and the living room base unit 3 receives the seismic information reception signal at the room base unit CPU 40 via the room base unit IF 39. . The room base unit CPU 40 performs control to switch the high-speed transmission switching unit 38 from the demodulation circuit 32 side to the room base unit CPU 40 side.

On the other hand, the control unit CPU 26 of the control unit 2 creates pictograms, character information, map information, other evacuation route information, and the like to be notified by the living room master unit 3 from the received earthquake information to create earthquake information data. The created earthquake information data is transmitted to the room base unit 3 via the CH switching unit 24 and the video transmission path, and the transmitted earthquake information data includes the room base unit IF39 of the room base unit 3, the earthquake information reception. It is received by the room master unit CPU 40 via the high-speed transmission switching unit 38 switched to the room base unit CPU 40 side by the signal. In the base unit CPU 33, information such as pictograms, character information, map information, and other evacuation route information to be displayed on the monitor 31 from the received earthquake information data is displayed on the monitor 31 via the video processing circuit 33.

As the display information, information such as “Seismic intensity 5 occurs after about 10 seconds. Please extinguish the fire and evacuate.” Is displayed. At the same time, a warning sound may be notified from the speaker 34.

Further, when the communication sensor 25 notifies that the video transmission path is being used as in the case where communication is performed between the collective entrance machine 1 and the living room master unit 3 when an earthquake occurs, the controller Under the control of the CPU 26, the CH switching unit 24 is controlled to control the video path and the communication path formed between the collective entrance machine 1 and the room base unit 3 that are performing communication and video transmission / reception. Further, control is performed so that a video path is formed by the room base unit 3 that receives the earthquake information and the video transmission path. In this way, even if the video transmission path is in use, it is controlled so that the earthquake information data can be forcibly transmitted using the video transmission path. Can be received.

When the earthquake information is received, it is also possible to transmit the earthquake information as an audio signal to the room master unit 3 using the call transmission path. Specifically, in the controller 2 that has received the earthquake information, the controller CPU 26 controls to form the communication path between the earthquake information receiver 5 and the room base unit 3 that is the object of the earthquake information by the transmission line for communication. The voice transmitted from the earthquake information receiver is broadcast on the transmission line for calls. Thus, the sound can be notified from the speaker 35 via the room base unit IF 39 of the room base unit 3 and the call circuit 36.

When the same sound data is included in the earthquake information data, the sound data of the earthquake information data can be preferentially notified from the speaker 35 by controlling to prohibit broadcasting. As a result, even when earthquake information cannot be transmitted from the video transmission path due to a transmission failure, or when the room master unit cannot receive the earthquake information, it is possible to broadcast by voice using the audio transmission path. Therefore, it is possible to receive earthquake information without fail.
