Description

  The present invention relates to an interphone system, and in particular, when an extension master unit is connected to a living room master unit, an extension master unit call button for calling the extension master unit is automatically displayed on the monitor of the living room master unit. It is related with the intercom system which can do.

  Conventionally, as this type of interphone system, an interphone system is known in which a plurality of extension base units are connected to a room base unit to which an entrance unit is connected.

  In this intercom system, when a room base unit receives a call from an extension base unit with a local call function set in advance, during the predetermined time until answering the call, the room base unit generates an extension call sound only from the room base unit. If the ringing is performed preferentially and there is no response within the predetermined time, a call operation is performed to another extension base unit connected to the living room base unit (see, for example, Patent Document 1).

  According to the intercom system having such a configuration, the local priority call target is the extension master unit, and the person who is the target of the call is called preferentially, so that a specific person can be called without inconvenience other people. You can call and talk.

  By the way, in such an intercom system, even if the extension master unit is not connected to the living room master unit, an extension for calling the extension master unit in advance to the living room master unit in preparation for the connection of the extension master unit in the future. A master call button is provided.

  However, such an extension master call button is unnecessary for a resident who uses the room master without connecting the extension master, and there is a problem that the operation of the room master becomes troublesome.

  As shown in FIG. 2, the extension base unit 3 includes an extension base unit CPU 30 for controlling each part (circuit) of the extension base unit 3, a base unit IF circuit 31, and an extension base for calling with a visitor. A machine call unit 33, an extension master monitor drive circuit 34, an extension master monitor 35 that displays images captured by the entrance camera 13 and a call button, and an extension master touch panel 36 are provided. The unit 33 includes an extension master phone call circuit 33a, an extension master phone microphone 33b, and an extension master phone speaker 33c. Here, the extension master CPU 30 is connected to the master IF circuit 31, the extension master call circuit 33a, the extension master monitor drive circuit 34, the extension master monitor 35 and the extension master touch panel 36, and the master IF The circuit 31 includes an extension call circuit 33a, an extension master monitor drive circuit 34, and a fourth transmission line L4. The extension master call circuit 33a includes an extension master microphone 33b and an extension master speaker 33c. An extension master monitor 35 is connected to each drive circuit 34.

  Next, the operation of the intercom system of the present invention configured as described above will be described. Note that the first transmission path L1, the controller 5, and the second transmission path L2 are provided between the entrance communication section 12 of the entrance machine 1 and the parent machine communication section 23 of each of the room base units 2a, 2b,. Since the communication path is formed through the same as the operation of the conventional intercom system, detailed description is omitted, and here, the extension master unit 3 is connected to the first living room master unit 2a. The operation will be mainly described.

  First, when the extension master unit 3 is not connected to the first room master unit 2a, the extension master unit CPU 20a is set not to be activated (invalidated) by the operation of the master unit touch panel 26. . By this setting operation, for example, an entrance button 25a, a management room button 25b, and an elevator button 25c are displayed on the parent device monitor 25 as shown in FIG.

  In this state, when the extension master unit 3 is connected to the first room master unit 2a via the fourth transmission line L4 (see FIG. 1), the initialization command and the extension master unit are transmitted from the extension master unit CPU 30. The ID is output, and these initialization commands and the extension master unit ID are sent to the master unit CPU 20 via the master unit IF circuit 31, the fourth transmission line L4, and the extension master unit IF circuit 22.

  When the initialization command and the extension master ID are detected by the master CPU 20, the extension master CPU 20a, which has been invalidated until now, is activated (validated) by the control of the master CPU 20. At the same time, the additional master unit ID is registered in the image memory 27. At the same time, the display data of the additional master call button is read from the image memory 27 and the display data is sent to the first master monitor 25. As a result, the extension master call button 25d is displayed on the first master monitor 25 as shown in FIG.

  Here, when the resident of the first room master unit 2a touches the extension master unit call button 25d, an extension master unit call signal containing the extension master unit ID is received from the master unit CPU 20 of the first room master unit 2a. Is output to the extension master unit CPU 30 via the extension master unit IF circuit 22, the fourth transmission line L 4, and the master unit IF circuit 31.

  When the extension master unit CPU 30 detects such an extension master unit call signal, the extension master unit call circuit 33a is controlled, and a ringing tone is emitted from the extension master unit speaker 33c. Here, by performing a predetermined operation in the extension master unit 3, a communication path is formed between the first living room master unit 2 a and the extension master unit 3.

  In the above embodiment, the case where an initialization command is transmitted from the extension master to the room master when the extension master is connected is described. However, when the extension master is connected, the room is When the master unit sends an initialization command to the extension master unit, and the extension master unit CPU that has received the initialization command returns an extension master unit ID to the room master unit, it is for the extension master unit. The same effect can be obtained even when the CPU is activated and the additional master unit ID is registered.

  In the preferred embodiment of the intercom system of the present invention, it is applied to an intercom system for collective housing, but the same effect can be obtained even if it is applied to an intercom system for a detached house.
