Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a response control device for making a call between an intercom and a telephone.

[0002]

2. Description of the Related Art Generally, each home is provided with an intercom. When a visitor presses an operation key attached to the entrance, a doorbell installed in the room sounds. Residents know that there is a visitor by the doorbell. The resident uses the communication device provided integrally with the doorbell to talk with the visitor, or goes directly to the entrance.

[0003]

As mentioned above, intercoms are convenient, but they can be abused to determine if a resident is at home. For example, there may be a case where a burglar presses an operation key to abuse to check whether or not a resident is at home.

[0004] Further, if the resident leaves the house, even if there is a visitor, it is not possible to respond to the intercom, so whether there is a visitor, if so, who was it, what requirements. I do not know whether it was.

The present invention has been made in view of the above-mentioned problems, and prevents an interphone from being abused for confirming the presence or absence of a resident. It is an object of the present invention to provide a response control device capable of responding to a response.

[0006]

According to the first aspect of the present invention, there is provided an operation key for sounding a doorbell of an intercom.
Means for detecting that the telephone key has been operated, calling means for calling a preset telephone number in response to the operation of the operation key 21, and telephones 14, 1 having received the call.
An electronic sound transmitting means 43 for transmitting an electronic sound corresponding to the ringing bell to the telephone after the telephones 5 and 16 are on-hook, and after the telephone receiving the call is on-hook. Means 44 for controlling a call so as to make a call between the telephone and the interphone.

The apparatus according to the second aspect of the present invention includes time setting means 46 for setting a time T1 from the timing of operating the operation keys 21 to the time of calling. In the present invention, the telephone includes a portable telephone, a fixed telephone, a pager, and the like.

[0008]

FIG. 1 is a block diagram showing the overall configuration of an intercom response system 1 according to the present invention, FIG. 2 is a block diagram mainly showing the configuration of a response control device 13, and FIG.
FIG. 3 is a diagram showing operation timing of each unit of the interphone response system 1.

In FIG. 1 and FIG. 2, an intercom answering system 1 includes an entrance unit 11, an indoor unit 12, a response control device 13, a public telephone network NW, and a telephone 1.
4, 15, 16 and the like.

The entrance unit 11 includes an operation key 21 for a visitor to press to call a resident, and an indoor unit 1.
2 and a television camera 23 for taking a picture of a visitor.

When the operation key 21 is pressed, the indoor unit 12 emits a sound to notify a resident of the presence of a visitor, a monitor 31 for displaying an image taken by the television camera 23, The receiver normally includes a receiver circuit 33 and a receiver 34 for making a call with a visitor.

The response control device 13 includes an operation detection unit 41, a call control unit 42, an electronic sound transmission unit 43, a call control unit 44, a line control unit 45, and a time setting unit 46. The operation detection unit 41 detects that the operation key 21 has been operated, and outputs a detection signal S1 to the call control unit 42. Detection signal S1
Is output when a set time T1 has elapsed since the operation key 21 was turned on after being turned on.
The time T1 can be adjusted by the time setting unit 46. The adjustment range is about several seconds to one minute, and is usually set to, for example, 5 seconds, 7 seconds, 10 seconds, or the like.
The time T1 may be measured after the operation key 21 is turned on after being turned on.

When the detection signal S1 is output, the call control unit 42 outputs a signal S2 for calling a preset telephone number. The line controller 45 makes a call to the public telephone network NW based on the signal S2. In this example, it is assumed that the portable telephone 14 is called. The telephone 14 rings.

In the calling control section 42, a plurality of telephone numbers to be called can be set in order. Calls are made in descending order of priority, and when no other party comes out, a call is made to the next-ranked number.

After the telephone 14 that has received the call is on-hook, the electronic sound transmitting section 43 outputs an electronic sound signal S3 corresponding to the doorbell 31 to the line control section 45. The line controller 45 transmits an electronic sound to the telephone 14 of the other party based on the electronic sound signal S3. Doorbell 3 as electronic sound
A sound close to the sound emitted from 1 is used. This is because the person who answers the called telephone 14 immediately hears this electronic sound that it is not a normal telephone but a call from the entrance unit 11. Therefore,
For example, an electronic sound called “ping pawn” often used as a normal chime is preferable. However, it is possible to use a bell sound called "ring ring", a buzzer sound called "boo", and various other electronic sounds.

The call control unit 44 controls the telephone 1 that has received the call.
After the phone 4 is in the on-hook state, voice control is performed so that a telephone call is made between the telephone 14 and the speaker 22 of the entrance unit 11. The call control unit 44 controls the speaker 2
2 and the telephone 14 can have a conversation. However, the electronic sound due to the electronic sound signal S3 cannot be heard from the speaker 22. Therefore, the visitor does not know that the resident is absent.

A power supply device for operating the response control device 13, an on / off switch for turning on or off the operation of the response control device 13, and a mode for switching the operation mode of the response control device 13 between a master and a slave. Switches and the like are provided.

The telephone 14 is portable as described above, the telephone 15 is fixed, and the telephone 16 is a pager. For pagers,
The response control device 13 can send a message.

Next, a method of using the intercom answering system 1 will be described. When the visitor presses the operation key 21,
The doorbell 31 rings. If a resident is present and picks up the receiver 34 and puts it on-hook, the speaker 22 and the receiver 3
4, and a call is made.

If the receiver 34 is not picked up even if the resident is absent or occupied, the response control unit 13 calls the predetermined telephone number after the set time T1 has elapsed. You. When the called telephone 14 is in an on-hook state, an electronic sound is transmitted from the response control device 13, and this can be heard by the receiver of the telephone 14. The receiver of the telephone 14 can immediately recognize from the electronic sound that the call is from the entrance unit 11 instead of a normal telephone, so that when the telephone 14 is answered, it is necessary to talk to a visitor at home. Have a conversation. As a result, the resident can have a conversation with the visitor as if he / she is at home, even though he / she is not at home.

Therefore, for example, the empty key is
When the user presses to confirm whether or not the resident is at home, even if the resident is absent, the user comes into a conversation as if he / she is at home, and such abuse is not performed.

In the above-described embodiment, the indoor unit 12 and the response control device 13 are formed separately, but they may be formed integrally. Entrance unit 11, indoor unit 12, response control device 13, or intercom response system 1 or the configuration, shape, number, control content,
The control order and the like can be appropriately changed according to the gist of the present invention.

[0023]

According to the present invention, it is possible to prevent the interphone from being misused for confirming the presence or absence of a resident, and to respond to a call by the interphone even when the user is away.
