Abstract

PURPOSE:To select an optional key telephone set from a doorphone and to call the key telephone set in one-touch by providing a circuit detecting a call signal from the doorphone and giving a command to the key telephone set to be called to a master equipment. CONSTITUTION:When a button corresponding to a key telephone set 20 of a one-touch dial section 40 is depressed, a call signal and a one-touch dial data are sent to a master equipment 1. A detection circuit 3 receives a call signal from a doorphone equipment 10 and a control section 4 receives the dial data from the doorphone equipment 10. A dial identification section 5 identifies to which extension number of which key telephone set the input dial data corresponds and the control section 4 gives a command to operate a sound source of the key telephone set 20. Thus, an optional key telephone set is selected from the doorphone to call it in one-touch.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a button telephone device having a doorbell device, more specifically, the doorbell is provided with a plurality of one-touch dials, one of which is selected and pressed. The present invention relates to a button telephone device that allows a selected button telephone to be called.

(Prior Art) Conventionally, this conventional key telephone device is configured to call a predetermined key telephone when a call is made from a doorbell.

(Unsolved Problem to be Solved by the Invention) Since the button telephone device of Jumei is configured to call a fixed key telephone from the doorbell in this way, it is not possible to call any key telephone from the doorbell with a single touch. There was a drawback.

An object of the present invention is to provide a button telephone device that can select any button telephone from a doorbell and call it with one touch.

(Means for Solving the Problems) In order to achieve the above object, a key telephone device according to the present invention is a key telephone device in which a main device accommodates a doorbell device and a plurality of button telephones, the doorphone device having a plurality of one-touch dials. and a circuit section that, when the one-touch dial is pressed, sends out a discharge signal and the extension number of the pressed button telephone compatible with the one-touch dial, and each of the button telephones is provided with a sound source for a door intercom, and the main device a detection circuit that detects all the calling signals from the door intercom device; a dial identification section that identifies the extension telephone from input dial data; and a control section that transmits the extension number of the button telephone to the dial identification section, operates the sound source of the button telephone to be called based on the data identified by the dial identification section, and outputs a ring tone for the doorbell. be.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a key telephone device according to the present invention.

In FIG. 1, the key telephone devices include a doorbell device 10, key telephones 20, 21, . The main unit 1 accommodates 2mf.

In this embodiment, only the parts directly related to the present invention are described.

The door intercom system 10 includes one-touch dial sections 40, .

The button telephones 20, 21, . . . , 2m each have a power source 30, 31, .

The main device 1 includes a doorbell device 1O and each button telephone 2.
0, 21, ~, 2m, and an interface circuit 2 that sends and receives signals, a detection circuit 3 that detects a calling signal from a doorbell, and a detection circuit 3 that identifies which key telephone extension number the input dial corresponds to. It is provided with a dial identification section 5 and a control section 4 in which the detection circuit 3 receives a calling signal, sends a dial to the dial identification section 5, and instructs a dial button telephone.

Next, the operation of this embodiment will be explained.

As an example, a case where the key telephone 20 is called from the door intercom device 10 will be described.

When the button corresponding to the button telephone 20 of the one-touch dial section 40 (the button telephone number "2"."0" gold is registered in the one-touch dial section 40 in advance) is pressed, a call signal and one-touch dial data "2""'0" are generated. '' is sent to the main device 1.

The detection circuit 3 receives a calling signal sent from the door intercom device 10 via the interface circuit 2, and sends the calling signal to the control unit 4.

When the control unit 4 receives the calling signal from the detection circuit 3, the control unit 4 receives dial data “2” from the door intercom device 10 via the interface circuit 2. Receive “o”2. Then, dial data "'2"0 is sent to the dial identification section 5.

The dial identification unit 5 receives the input dial data "2".
．． The extension number of the key telephone set "O" is fully identified, and the identified result is sent to the control unit 4.

When the control unit 4 receives all the identification data of the button telephone to be called by the one-button telephone 20'', it issues an instruction to operate the sound source of the button telephone 20 via the interface circuit 2. , sound source 3
From 0, a ringtone "Bing Bong" is emitted.

(Effects of the Invention) As described above, the present invention provides a doorbell with a plurality of one-touch dial units and a circuit that sends out a calling signal and the extension number of the pressed button telephone compatible with one-touch dialing, and each button Each of the telephone devices is provided with a sound source, and the main device is provided with a circuit for detecting a calling signal from a doorbell and issuing an instruction to the key telephone to be called.

As a result, it is possible to select any button telephone and make a call with a single touch rather than a doorbell.
