Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

1 is a block diagram of an interphone and an external telephone automatic connection device according to the present invention.

As shown therein, an interphone terminal 10 including a speaker and a speaker for notifying that the visitor has arrived and making a call with a person in the house; A camera 20 for photographing the visitor; An interphone (30) for making a call with a visitor through the interphone terminal (10) and monitoring a visitor captured by the camera (20); An automatic telephone connection unit 50 for automatically connecting the interphone 30 and the internal telephone 40 when the visitor arrives when the external telephone number is set by the user in the outing mode; A telephone that connects the voice and video of the visitor obtained from the interphone 30 to the external telephones 60 and 70 through a telephone line, and the voice input from the external telephones 60 and 70 connects to the interphone 30. It consists of 40.

Referring to Figure 2 attached to the interphone and the external telephone automatic connection device according to the present invention configured as described above in detail as follows.

First, in order for a user to go out, an external telephone 60 and 70 may be notified by turning on a switch for designating an outing mode provided in the automatic telephone connection unit 50, and at the same time, checking the visitor from the outside. Enter your phone number.

When the visitor arrives in such a state, the doorbell provided in the interphone terminal 10 is pressed, and the signal is transmitted to the automatic telephone connection unit 50 by tone the interphone 30.

Then, the telephone automatic connection unit 50 drives the telephone 40 to automatically dial the external telephone number entered by the user.

In this case, even when the user is outside, it can be seen that the visitor has arrived through the external telephones 60 and 70.

Here, the external telephones 60 and 70 are composed of two, one of which is a general telephone 60 capable of transmitting and receiving voice only, and the other is a video telephone 70 capable of voice and video. .

On the other hand, ringback tone is generated when automatic dialing is made, and the telephone automatic connection unit 50 searches for the number of ringback tones, and the user calls even when the number is more than a predetermined number of times (this can be set by the user at will). If you do not do this, the connection is automatically disconnected.

On the contrary, when the call is received from the external telephones 60 and 70, the telephone automatic connection unit 50 connects the interphone 30 and the telephone 40.

Then, the voice input from the interphone terminal 10 is transferred to the external telephones 60 and 70 through the interphone 30 and the telephone 40 in sequence, and the voices of the external telephones 60 and 70 are reversed from the above. As a result, the telephone 40 and the interphone 30 are sequentially transmitted to the speaker of the interphone terminal 10 so that the user can talk with the visitor from the outside.

In addition, when the external telephone is the video telephone 70, the visitor image captured by the camera 20 is transferred to the video telephone 70 through the interphone 30 and the telephone 40 in sequence, thereby allowing the user to receive the video telephone 70. ) Will tell you who the visitor is.

And when a signal is input from the outside by using a numeric button or a specific button of the telephone to enter the visitor into the home, the signal is transmitted to the telephone automatic connection unit 50 through the telephone 40, the telephone automatic connection unit ( 50 recognizes this and gives a corresponding control signal to the interphone 30 so that the door opens automatically.

As described above, the present invention can automatically connect an interphone and an external telephone while going out, and thus, there is an effect of confirming a visitor from the outside.

In addition, there is an advantage that can open the door automatically from the outside.
