[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of an intercom system. Here, an intercom system of a two-family house composed of a parent household and a child household is shown, but the present invention is not limited to this, and a plurality of intercom handsets and a plurality of intercom masters (master and sub-master) are provided. For example, a system configuration in which doorphone slaves are installed at the entrance and the back door, and the base units that respond, respectively, may be different.

In the illustrated two-family house, one door phone slave unit (B1, B2) is provided at the entrance of each household in order to handle visitor separately, and intercom masters installed corresponding to each household are provided. Machine A or intercom secondary master A1
And A3, and extension calls (between different households and between same households) between the master units A and A1 to A3 are enabled.

Two intercom units B1 and B2 are connected to the intercom master unit A installed in the parent household, and the intercom sub master units A1 to A3 are serially connected to the intercom master unit A. . Here, the parent household has two units, the intercom master unit A and the secondary master unit A1, and the child household has the secondary master unit A.
2 shows an example in which two units A3 are installed. In addition,
The connection form is not limited to the illustrated one. For example, a form in which the master unit A and the auxiliary master units A1 to A3 are connected in parallel may be used. , A1 to A3 may be used as long as they can respond.

In such a configuration, each of the master units A and A1
To A3, as a response selection setting means, a slave unit B for sounding a ringing tone, which is constituted by a dip switch or the like.
Slave sound selection switches sw, sw1 for setting 1 and B2
To sw3, and by changing this setting for each household, only one of the two intercom slave units B1 and B2 is ringed and answered. I have.

Here, the child unit ringing selection switches sw and sw1 of the parent units A and A1 of the parent household ring the ringing tone only to the child unit B1, and the child units ringing of the parent units A2 and A3 of the child household. The selection switches sw2 and sw3 are set to ring a ringing tone only to the slave B2. If both households are at home, the intercom system can be used without any problem by the above configuration. However, if one of the households is away (absent), the doorphone handset addressed to the other household is self-addressed. When asking a proxy response for a call from B1 or B2, the present system operates as follows.

In order to realize the proxy response function, each of the master units A,
A1 to A3 are provided with proxy response lamps (LEDs) 1 and 11 to 13 as proxy response display sections and proxy response buttons b and b1 to b3 as proxy response setting switches. For example, a case in which the child household is out of the office, and a case where the proxy response function is set in the sub-base unit A3 will be described. Tell the effect. If permission for proxy response is obtained by this call, the proxy response button b3 of the sub-parent device A3 of the child household is operated. Then, all parent devices A of both households,
The proxy response lamps 1 and 11 to 13 of A1 to A3 light (or blink). As a result, the child household knows that a proxy response has been requested, while the parent household knows that subsequent calls include calls to the child household.

That is, the master unit A3 that has operated the proxy response button b3 and the master units A, A1, and A2 that have received the proxy response control signal through the signal line L are connected to the slave unit sound selection switch s.
The settings of w, sw1 to sw3 are temporarily invalidated, and a ringing tone is sounded even if a call is made from any of the intercom slave units B1, B2. Thereafter, when the resident of the child household returns home, by operating one of the proxy response buttons b2 and b3 of the parent devices A2 and A3 in the own household, the proxy response lamps 1 and 2 of all the parent devices A and A1 to A3 are operated. l1-l3
Is turned off, and the slave unit sound selection switches sw, sw1 to sw3
Setting returns to valid.

As described above, according to the present invention, when the proxy response function is set / released for the intercom master unit A and the sub master units A1 to A3, the proxy response functions of the other master units A and A1 to A3 are also set at the same time.・ Can be released. In this case, to distinguish it from setting individual proxy responses,
Apart from the proxy response buttons b, b1 to b3, each master unit A, A
A proxy response simultaneous setting button may be provided in 1 to A3.

The setting of the proxy response function is not limited to this.
When b1 to b3 are operated, the parent device A of the own household
A1 to A3 are slave unit sound selection switches sw, sw1 to sw
3, the proxy response function is set only to all the master units A, A1 to A3 or specific master units A, A1 to A3 of the other household (slave unit sound selection switch s).
w, sw1 to sw3 may be invalidated). In this case, since the household to be absent knows that they have requested a proxy response when they return home, the proxy response lamps l, l1 to l are independent of the setting of the proxy response function.
3 needs to be lit.

Also, when the proxy responding side receives the contact, the proxy responding buttons b, b1 to b1 of the base units A, A1 to A3 are received.
The proxy response function may be set by operating b3. At this time, the ringing of the slave unit sound selection switches sw and sw1 to sw3 of all the master units A and A1 to A3 may be invalidated. However, only the operated master units A and A1 to A3 and all of the own households are disabled. Slave sound selection switch s for master units A and A1 to A3 only
w, sw1 to sw3 may be invalidated.

As described above, the proxy response function of the intercom master unit A and the sub master units A1 to A3 is performed by the respective master units A and A1.
It can be set and canceled independently for each of A3. This means that, besides being able to be set individually by button operation on each machine, the master machine A can also be set to each of the sub master machines A1 to A3, or any of the sub master machines A1 to A3 to other master machines A and A1.
ＡA3 are simultaneously transmitted, and the proxy response function is individually set.

Next, FIG. 2 shows an internal configuration of the intercom master units A, A1 to A3 for realizing the proxy response function. Here, signal line L is connected to intercom master unit A.
All of the plurality of intercom sub master units A1 to A3 serially connected via (multiple signal lines) have the same configuration, and only one of them (A1) is shown.

In the base unit A, the CPU 1 controls the following units.
When a call from any of B2 is detected, the CPU 1
Is one of the slave units B1, B2
, And power is supplied from the slave unit power supply circuit 5 to the slave units B1 and B2. At this time, if the proxy response function has been set, the ringing sound is generated from the speaker 9 by the ringing sound generation circuit 8 without reference to the setting of the child device ringing selection switch sw. On the other hand, if the proxy response function has not been set, a ringing tone is sounded if the calling slave units B1 and B2 are set to "ringing ON" with reference to the setting of the slave ringing selection switch sw. When the “ringing OFF” is set, the ringing tone is not ringed.

When the ringing tone is to be sounded, the TV circuit 6 is operated at the same time to display an image of the slave units B1 and B2.
That is, this drawing shows a case where the intercom slave units B1 and B2 are intercom slave units with a camera, and the intercom master unit A and the intercom sub master unit A1 are both intercom master units with a monitor television. If the user sees the image projected on the TV circuit 6 and responds by picking up a handset (not shown) or the like, the communication signal is transmitted and received through the multiplexing circuit 4, and the communication circuit 7, the speaker 9, and the microphone 10 are transmitted.
Enables intercom calls.

When the calling signal is detected by the calling detecting circuit 2, the base unit A sends the called handset B1, B1 from the multiplexing circuit 11 by the command transmitting / receiving circuit 12.
A call command indicating B2 is sent to the sub master unit A1. When the CPU 21 of the sub master unit A1 receives the signal multiplexed by the multiplexing circuit 27 and receives the call command by the command transmission / reception circuit 28, similar to the master unit A, the setting of the proxy response function, It is determined whether or not a ringing tone is to be sounded based on the setting of the child device ringing selection switch sw1. When the ringing is performed, the ringing tone generating circuit 24 causes the speaker 25 to ring.

When the ringing tone is sounded, the TV circuit 22 is operated at the same time to display the images of the slaves B1 and B2, so that if a call is answered, a call signal is transmitted and received through the multiplexing circuit 27. , Communication circuit 23 and speaker 2
5. The interphone call is enabled by the microphone 26. In the above, the case where the proxy response has already been set has been described. However, when the proxy response function is set, if the proxy response buttons b and b1 are operated, the CPUs 21 detect this and the proxy response lamp is set. 1 and 11 are turned on to set the proxy response function, that is, the slave unit sound selection switches sw and sw
1, the command transmission / reception circuit 12,
At 28, a proxy response command is transmitted to the other master units A and A1. The other master units A and A1 have a command transmitting / receiving circuit 1
When the proxy response command is received by the control unit 2 or 28, the proxy response lamps l and 11 are turned on and the proxy response function is set, that is, the slave unit sound selection switches sw and sw1.
Disable settings. When canceling the proxy response function, a proxy response release command is transmitted and received, and the setting of the slave unit sound selection switches sw and sw1 is returned to valid.

Here, a case has been described in which the proxy response function is simultaneously set and released for all the master units A and A1 to A3. As described above, the proxy response function is individually set and released. In this case, the addresses of the parent devices A and A1 to A3 targeted by the command are added to the proxy response command and the proxy response release command, and the parent devices A and A1 receiving the command are added. ~ On the A3 side,
What is necessary is just to determine whether the command is addressed to itself, and to operate.

Next, another configuration of the intercom system of the present invention will be described. Each of the master units A, A1 to A3 can be configured to make the ringing sound at the time of calling from each of the doorphone slave units B1, B2 different. In this case, the CP of master unit A
U1 depends on the calling source detected by the call detecting circuit 2, and the sub master unit A1 (A2, A3) responds to the calling command received by the command transmitting / receiving circuit 28 by the calling sound generating circuits 8, 24. Change the ringing tone.

The present invention is also applied to a system in which the doorphone slave units B1 and B2 are not provided with a camera, and each of the base units A and A1 to A3 is not provided with a monitor television (TV circuits 6 and 22). The invention applies. Further, the sub master unit A
The present invention can also be applied to an intercom system including only one intercom master unit A without connecting 1 to A3 and a plurality of intercom slave units B1 and B2. In this case, the intercom master unit A operates the slave unit sound selection switch sw
Set the handset B1 or B2 for sounding the ringing sound,
When the proxy response button b is operated,
A ringing tone is also sounded for calls from B1 and B2.

In other words, the proxy response function of the base unit A at this time determines whether the intercom slave units B1 and B2 to respond to are only one specific slave unit or both (all) slave units. Performs the change function. For example, during the daytime, the proxy response button b is operated (proxy response function setting) so that a ringing tone sounds for all the slaves B1 and B2, and at night, the proxy response button b is operated again (proxy response button). Function release), a ringing tone can be sounded only for a specific slave unit B1 or B2.

[0035]

As can be understood from the above description, the intercom system according to the present invention has the following effects. According to the first aspect, the intercom master device and the interphone sub master device can perform a proxy response that also responds to a call from a device other than a preset child device. Therefore, in a two-family house or the like, when leaving home, if the other household is asked for a proxy response, it is possible to hear the important customer's business.

In the second aspect, the intercom master unit and the intercom sub master unit are provided with the proxy response setting switch, so that the proxy response can be set and released by a simple operation. According to the third aspect of the present invention, if the proxy response setting switch is operated, it is only necessary to invalidate the setting of the response selection setting means and enable the response to the call from all the intercom slaves. Can be dealt with.

According to the fourth aspect, since the proxy response display section is provided in the intercom master unit and the interphone sub master unit, it is easy to confirm whether the proxy response function is set or canceled in each master unit. it can. According to claim 5,
According to the sixth aspect, when the proxy response function is set / released on the intercom master, the proxy response function of the other master is simultaneously set / released when the proxy response function is set / released on the interphone sub-master. Since it can be canceled, there is no need to perform the setting operation for each master unit, which is convenient.

According to the seventh aspect, the proxy answering function can be set and canceled independently for each of the intercom master unit and the sub master unit.
You can respond by proxy according to your living situation. According to the eighth aspect, each base unit differs in the ringing sound at the time of calling from each intercom slave unit. Therefore, while the substitute response function is set, whether the call is addressed to itself or the call to be substituted by the substitute. It is easy to determine what is.

According to the ninth aspect, a television intercom system having a proxy response function can be constructed. According to the tenth aspect, since the interphone master unit connected to the plurality of doorphone slave units is serially connected to the interphone sub master unit, the wiring is not dispersed, the construction is easy, and the system wiring can be simplified.
