BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of an intercom system for an apartment house according to the present invention will be described.
This will be described with reference to the drawings.

As shown in FIG. 2, the intercom system for an apartment house according to the present invention includes a front door 5 installed at an entrance of an apartment house and a living room main unit 4 installed in a plurality of dwelling units of the apartment house. , A common bus 6 that connects the entrance device 5 and the plurality of living room master devices 4,.
, And a bus I / F module 1 for supplying DC power to the entrance device 5 and the plurality of living room master devices 4,...

The entrance machine 5 is connected to a common bus 6 and
It is composed of a call module 2 for making a call, and a plurality of switch modules 3 connected to the call module 2 for selecting a parent unit in the room. As shown in FIG. 1, the communication module 2 has a multiplexing / demultiplexing circuit 26 connected to the common bus 6 via an impedance upper circuit 21 for increasing the input impedance to a high impedance. A communication circuit 22 including a microphone M, a speaker S (FIG. 2), etc., a data transmission / reception circuit 24 connected to a control circuit 23, and a power supply circuit 25 for supplying power to each circuit of the entrance machine 5 are connected respectively. ing. The control circuit 23 is connected to the communication circuit 22 and controls the communication circuit 22. As shown in FIG. 1, the switch module 3 includes a switch control circuit 33 to which a call switch 31 and an illumination circuit 32 illuminating a name card 34 arranged in parallel with the call switch 31 are connected. The control circuit 33 is connected to the control circuit 23 of the communication module 2. In each of the other plurality of switch modules 3,..., The switch control circuits 33 are connected in series.

As shown in FIG. 1, the living room master unit 4 has a multiplexing / demultiplexing circuit 46 connected to the common bus 6 via an impedance upper circuit 41 for increasing the input impedance to a high impedance. The circuit 46 includes a communication circuit 42 including a handset HS, a calling speaker CS (FIG. 2), a data transmission / reception circuit 44 connected to a control circuit 43, and a power supply circuit for supplying power to each circuit of the living room master unit 4. 45 are connected to each other, and a call volume changeover switch 47 for switching a call volume of a call speaker CS included in the call circuit 42 is connected to the call circuit 42. The control circuit 43 is connected to the ring volume switch 47 and the call circuit 42, and outputs a switching signal according to the switching operation of the ring volume switch 47 to the entrance device 5.
Switch control circuit 3 of the corresponding switch module 3
3 and controls the communication circuit 42.

As shown in FIG. 1, the bus I / F module 1 includes an impedance upper circuit 12 connected to a DC power supply via a power supply circuit 11 to increase the output impedance to a high impedance.

In the intercom system for a multi-family housing configured as described above, when a call operation is performed by the call switch 31 of the switch module 3 which can call the room master unit 4 of a predetermined dwelling unit at the entrance machine 5, a call data signal is generated. The signal is transmitted to the selected parent device 4 via the communication module 2 and the common bus 6. The control circuit 4 of the living room master unit 4
Reference numeral 3 causes the calling speaker CS of the calling circuit 42 to emit a ringing sound based on the calling data signal. Resident responds to this call by handset H of communication circuit 42 of living room base unit 4.
When the call operation is performed in S, a communication path is formed between the selected parent device 4 and the entrance device 5, and the communication circuit 42 of the parent device 4
And the communication circuit 22 of the entrance device 5 allows the user to make a telephone call using a voice signal.

On the other hand, if the resident of the dwelling unit does not want to ring the ringing speaker CS of the living room base unit 4 in response to such a call, the ringing sound of the calling speaker CS is turned on by the ringing volume switch 47 of the living room base unit 4. Set so that does not ring. As a result, the control circuit 43 of the living room master unit 4 transmits a switching signal indicating that “the calling speaker CS does not want to ring”. This switching signal is received by the switch control circuit 33 of the corresponding switch module 3 of the entrance device 5, and the switch control circuit 33 causes the lighting circuit 32 to illuminate the name card 34, for example, to reduce the brightness of the lighting. Is transmitted to the lighting circuit 32. Therefore, since only the brightness of the illumination illuminating the name card 34 of the corresponding switch module 3 of the entrance device 5 is dark, the living room device 4 cuts off the ringing sound of the call speaker CS on the entrance device side. Can be easily understood. When it is desired to ring the calling speaker CS of the living room master unit 4, the ringing sound of the calling speaker CS is set by the ringing volume switch 47 of the living room master unit 4, so that the switch module 3 is sounded.
Can be made the same as the brightness of the illumination that illuminates the registration card of another switch module.

In the intercom system for an apartment house having such an intercom function, the stabilized DC power is supplied from the impedance upper circuit 11 of the bus I / F module 1 to the common bus 6, and the impedance upper circuit of the entrance machine 5 is provided. The power supply circuit 25 via the impedance upper circuit 41 of the main unit 21 and the plurality of living room master units 4,.
Are supplied as standby power to the common bus 6 by the bus I / F module 1 via the impedance upper circuit 11 which performs a constant current operation. Power supply and entrance machine 5
Since the impedance upper circuit 21 of the front door unit 5 performs a constant current operation when the power is received by the main unit 4, and the impedance upper circuit 41 of the main room unit 4 performs the constant current operation when the power is received by the main room unit 4. Bus I / on bus 6
F module 1, entrance device 5 and a plurality of living room master devices 4.
.. Can be prevented from lowering the AC impedance of the common bus 6. Therefore, the transmission loss of the common bus 6 can be reduced, and the transmission state of the data signal and the audio signal can be stabilized.

In the preferred embodiment of the intercom system for a multi-family house according to the present invention described above, the entrance machine is used to determine which of the room units has cut off the ringing sound. Although the brightness of the light for illuminating the name card of the switch module of the above is changed, the color of the light for illuminating the name card may be changed.

[0020]

As is apparent from the above description, according to the intercom system for a multi-family housing of the present invention, when the base unit of the living room is set so as not to sound the ringing sound by the ringing volume changeover switch, the main unit of the living room is set. In order to indicate that the machine has cut off the ringing tone, the illuminance and color of the lighting of the switch module corresponding to this room main unit of the front door are changed. It is easy to see that the ringing tone has been cut.
