2 etc., from the central monitoring board 4 to the home controller 1
It relays and branches broadcast audio and data transmission between the home controller 1, common entrance unit 2, and central monitoring board 4.

The central monitoring board 4 controls each home controller 1 and the communal entrance machine 2, receives data from these devices 1.2, and performs emergency broadcasting according to the contents. This central monitoring panel 4 is placed, for example, in a manager's room in a housing complex consisting of one building, and in a separate management layer M, etc. in a housing complex consisting of multiple buildings.

Next, the operating procedure and operation of each device when performing broadcasting in the housing complex management system shown in FIG. 1 will be explained.

When making an emergency broadcast or service broadcast, etc., the administrator selects the broadcast mode using the mote 9 switch (not shown) on the central monitoring panel 4, and then selects the broadcast mode (not shown) for the next residential unit group to be broadcast. Input by etc.

As shown in Fig. 3, the central monitoring board 4 cyclically transmits data to the communal entrance unit 2, and when the broadcast mode is selected, it is directly connected to the home controller 1 of the selected housing group. The transmission line 7 transmits a signal CTR containing control data for setting the broadcast mode of the home controller 1 of the housing unit group code and the housing unit group code as data following the address data ADH representing the communal entrance unit 2.
ζI will send it to you. ST is a start signal indicating the end of the transmission message from the central control panel 1, and EN□D is an end mark indicating the end of transmission of one message. As for this control data, the broadcasting data may be cyclically transmitted to each common entrance unit 2 that has jurisdiction over the above-mentioned residential unit group at all times during the broadcast, but the broadcast start data may be transmitted once or multiple times at the beginning of the broadcast. The control data may be transmitted only when the operation mode is changed, such as transmitting the control data once and then transmitting the broadcast end data after the broadcast ends.

The control unit 27 of the communal entrance device 2 receives the signal sent to the transmission line 8, and reads the address data AD in this signal.
When R matches the address of the own station, the following residential unit group call r and control data are taken in.

Next, the control data (including data other than the scanning monitor setting data) that has been imported into all the home controllers of the dwelling units that make up this dwelling unit group by referring to turn 4 of the dwelling unit corresponding to this dwelling unit group court 9 is sequentially transmitted. . Data transmission from the two common entrance machines is carried out cyclically via the transmission line 7 in a format similar to that shown in FIG.

In each station controller 1, the transmission terminal section 16 constantly monitors the signal sent out over the transmission line 7i, and the address data ADR transmitted by this signal is matched with the host terminal of the own station. Then, the control data CTR following the address data ADR is imported, and this control data CTR is
A security signal or an unlock signal, etc., is sent in response to the switch 8, and the switch 8 is then
1. Performs opening/closing control of 82 and S3.

That is, first, it is determined whether or not the security information indicates an abnormality (step 100), and in the case of an abnormality, it is determined whether the control data CTR includes call information from the Kyodo entrance unit 2, that is, a call is in progress. It is determined whether or not (step 101).

If a ring is in progress, a process is executed in which only the switch S3 is closed in step 102, whereby the output signal of the ring tone generating circuit 8 is input to the amplifier 1'3, and the ring tone is output from the speaker 14. sounds (e.g. beep,
A tattered sound) is pronounced. Note that the ringing tone generation circuit 18 has a function of creating an oscillation waveform according to the logic signal from the transmission terminal section 16.

On the other hand, if the determination in step 101 is NO, a process of closing only switch S2 is executed in step 103, whereby the output of the alarm sound generation circuit 17 is applied to the amplifier 13, and the security signal is output from the speaker 14. An alarm sound indicating an abnormality is output.

If it is determined in step 100 that the security is not abnormal, a determination is made in step 104 as to whether or not the control data CTR includes broadcast information, that is, whether or not the broadcast is in progress. If so, it is determined in the next step 105 whether or not it is being called. And if it's not calling,
A process of closing only the switch S1 is executed (step 106), thereby connecting the broadcast line 6 and the amplifier 13. As a result, the voice input by a manager or the like from a transmitter (not shown) of the central monitoring board 4 is broadcast via the speaker 14. Also, if the call is in progress, switch S
3 is executed (step 107).
), this causes the speaker 14 to generate the ringing tone described above.

Next, if it is determined in step 104 that the broadcast is not in progress, a determination is made in step 108 as to whether or not the call is in progress. If the vehicle is not in the mountain, all of the switches 81, 82 and S3 are not closed (step xo9), and the 2 output is output from the speaker 14.

As is clear from the above description, in this embodiment, for example, when an alarm is generated due to a security abnormality or when the alarm is being broadcast, the home controller is not activated. 1
When called, the above-mentioned alarm sound or broadcast sound is stopped and a ringing sound is output from the SHI0-power 14. Therefore, the inconvenience of the ringing tone being interrupted by the alarm or broadcast sound is avoided.

Note that the determinations in steps 101, 105, and 108 are as follows:
The answer is YES only while the control data CTR includes call information, that is, only while a call is being made. .

Also, in the above embodiment, the alarm sound is generated by the alarm sound half circuit 17, but this is a ringing sound generation circuit! 8 may be created. In this case, the switch S2 is naturally connected to the same circuit 18.

(Effects of the Invention) As described above, according to the present invention, while a call signal from the main device is input to the terminal, the broadcast sound stops even if the broadcast signal is input to the terminal number. be done. Therefore, it is possible to prevent the inconvenience of the ringing tone being drowned out by the broadcast sound, and to facilitate the communication.
