SUMMARY OF THE INVENTION However, in the above-mentioned conventional housing complex communication device, since broadcasting is performed via the broadcasting wiring 22, a dedicated wiring for the broadcasting wiring 22 is required and there is a problem that the cost is high.

Also, since broadcasting is performed through one broadcasting wiring 22,
For example, when an apartment house is composed of a plurality of buildings, there is a problem that group broadcasting, which selectively broadcasts each building, cannot be performed.

In view of the above problems, it is an object of the present invention to provide a collective housing communication device that can omit dedicated wiring for broadcasting and can perform group broadcasting for each of a plurality of dwelling units.

Means for Solving the Problems In order to achieve the above object, the present invention is connected in series for each group via a control line and a communication line, and a call signal of itself and a group broadcast of itself through the control line. Multiple intercom units that receive call signals for
A master unit that is connected to the control line and the call line and sends a call signal for each dwelling unit intercom and a call signal for group-by-group broadcasting to this control line is sent from the master unit to the control line for the dwelling unit intercom. In the case of being sent, while sending the calling signal of the dwelling unit intercom to the control line of the group of the dwelling unit intercom,
By connecting the call line of the master unit and the call line of the group of the dwelling unit intercom, a call path between the master unit and the dwelling unit of the dwelling unit is formed, and a call signal for broadcasting by group from the master unit to the control line. Is sent, the call signal for group-by-group broadcasting is sent to the control line of the group of the dwelling unit intercom, and by connecting the call line of the base unit and the call line of the group, the base unit and its group are connected. This is to form a communication path with the dwelling unit intercom.

Effect of the Invention With the above-described configuration, the present invention allows the communication line to be used both for communication and for broadcasting, so that the dedicated wiring for broadcasting as in the conventional example can be omitted, and the dwell unit intercom can be provided for each group. Since the control line is connected to the communication line via the communication line, group broadcasting can be performed for each of a plurality of dwelling units.

The control unit 32 of the main device 23 closes the relay 43 by the signal indicating the broadcast of the calling signal, and the ridge unit 33
The relay 36 is closed and a call signal similar to the case shown in FIG. 3B is output to the control line 60.

The transmitter / receiver circuits 53 of the dwelling unit intercoms 25 to 28 each detect the call signal for broadcast by group and relay 54
Close.

Therefore, the voice signal from the microphone 52 of the base unit 24 is the call circuit 50, the relay 49, the call line 65, the relay 43, the transformer 44, the amplifier 38, the transformer 37, the relay 36, the call line 61,
Dwelling unit intercom 26-28 relay 54, call circuit 55, amplifier
Playback via the speaker 58 and speaker 59
28 can be broadcast only to the house where it was housed.

In addition, preset numbers such as broadcasts for all buildings,
When this number is dialed from the master units 24 and 25, the relays 36 and 40 of the unit units 33 and 34 of all the buildings are configured to be closed, so that the broadcasting of the entire building is also possible.

When the call line 65 is not used for this call or broadcast, the BGM sound source 46 is connected to the call line 65 by the relay 45, so that BGM broadcasting for the entire building or each building is also possible.

Further, in the above embodiment, the call signal is a signal indicating a call or broadcast, a signal indicating the building of the dwelling unit in which the dwelling unit intercom is installed, and a signal indicating the dwelling unit intercom, but as shown in FIG. It is also possible to form a plurality of communication paths by adding a signal indicating the communication path number and increasing the number of wires.

EFFECTS OF THE INVENTION As described above, the present invention is connected in series for each group via a control line and a communication line, and receives its own call signal and its own group broadcast call signal via the control line. It is equipped with a plurality of dwelling unit intercoms and a master unit that is connected to the control line and the call line and that sends out the call signal for each dwelling unit intercom and the call signal for group broadcasting to this control line. When a call signal to the dwelling unit intercom is sent, the calling signal of the dwelling unit intercom is sent to the control line of the dwelling unit intercom group, and the call line of the master unit and the call line of the dwelling unit intercom group are connected. Form a call line between the master unit and its dwelling unit intercom, and call from the master unit to the control line for broadcasting by group. When a signal is sent, the call signal for broadcasting by group is sent to the control line of the group of the dwelling unit intercom, and by connecting the call line of the base unit and the call line of the group, Since the communication path with the dwelling unit intercom of the group is formed, the communication line can be used for both communication and broadcasting. Therefore, the dedicated wiring for broadcasting as in the conventional example is omitted. Further, since the dwelling unit intercom is connected to each group via the control line and the communication line, group broadcasting can be performed for each of a plurality of dwelling units.
