Description

External broadcasting group controller and control method of key phone system

The present invention relates to a device for controlling an external broadcast group of a keyphone system and a control method thereof. In particular, when an external broadcast is performed through a keyphone system, the broadcast zone is divided into several groups to be broadcast unnecessarily as a whole. The present invention relates to an external broadcast group control apparatus and a control method of a key phone system that can not only prevent the broadcast but also broadcast only to the group that should listen to the broadcast.

As is well known, a general key phone system is a system that manages and controls all functions according to the use of a key phone, such as ring signal generation, setting music generation, and various state voice services.

On the other hand, the external broadcast control device using a conventional key phone system, as shown in Figure 1, a key phone telephone (1) with a broadcast button for broadcasting; It is characterized in that it comprises a key phone main unit (2) connected to the signal output terminal of the key phone 1, inputs the broadcast data output from the key phone phone 1 and performs a broadcast operation through a speaker.

In the conventional external broadcasting control apparatus using the keyphone system, when the user broadcasts using the keyphone system, when the broadcast button of the keyphone telephone 1 is turned on, the keyphone main apparatus 2 is connected to the keyphone telephone 1. After inputting the broadcast data outputted from), the broadcast setup mode was selected, and the broadcast operation was performed through the speaker.

However, the external broadcast control apparatus using the conventional keyphone system as described above does not have to listen to the broadcast because the broadcast cannot be controlled by group and always broadcast as a whole when the external broadcast is performed using the keyphone system. As the groups listened to the broadcast unnecessarily, for example, when a company uses an external broadcasting device, there is a problem that interferes with work.

An object of the present invention is to solve the above-mentioned conventional problems, in particular, when the external broadcasting through the TIP system, by dividing the broadcast zone into several groups, not only to prevent unnecessary whole broadcasting. Rather, the present invention provides an apparatus for controlling an external broadcast group of a key phone system and a method of controlling the same, in which a broadcast can be broadcast only to a group that must listen to a broadcast, so that listeners who do not need to listen to the broadcast can normally perform a task.

In order to achieve the above object, the apparatus for controlling an external broadcast group of a keyphone system of the present invention includes: a keyphone telephone for selecting a broadcast button and a dial for broadcasting; A keyphone main unit connected to the signal output terminal of the keyphone telephone to analyze data output from the keyphone telephone to set a broadcasting zone; A signal generator which is connected to the signal output terminal of the key phone main unit and generates a noise canceling signal (hereinafter referred to as A1) and a zone setting request signal (hereinafter referred to as A2); A zone setting signal generation unit connected to the signal output terminal of the signal generation unit, receiving an A2 signal output from the signal generation unit, and outputting a zone setting signal; A time delay unit connected to the signal output terminal of the signal generator, receiving the A1 signal output from the signal generator, and time-naturalizing the A1 signal; A relay driver connected to the signal output terminal of the time delay unit to open a relay; It is characterized in that it is connected to the signal output terminal of the zone setting signal generator and the relay driver, and comprises a broadcast zone setting unit for setting the zone.

On the other hand, the external broadcast group control apparatus of the keyphone system of the present invention, the initial value determination step of determining the initial value of the system; A digit checking step of determining whether the broadcasting button is turned on after the initial value determining step, checking a digit if it is turned on, and turning on an external paging (EXT-PA); A pulse generation step of determining whether a dial is pressed after the digit checking step, and when the dial is pressed, turning on / off the EXT-PA relay by the number of dials; A group broadcasting step of broadcasting to a desired group through a speaker after the pulse generating step; An EXT-PA relay OFF step of determining whether the broadcast button is OFF after the group broadcast step and turning off the EXT-PA relay when it is OFF; After the EXT-PA relay OFF step, it comprises a re-initial value setting step for setting the initial value.

The apparatus for controlling an external broadcast group and a method of controlling the same according to the present invention, the broadcast zone is divided into several groups when the external broadcast is performed through the keyphone system, thereby preventing unnecessary broadcasting as a whole. Only the group that should listen to the broadcast can be broadcast only to the group, so that the listeners who do not need to listen to the broadcast can perform the work normally.

Hereinafter, with reference to the accompanying drawings, the configuration and operation for an embodiment according to the technical idea of the external broadcast group control apparatus and the control method of the present invention key phone system will be described in detail as follows.

EXAMPLE

As shown in FIG. 2, the present invention firstly connects the signal output terminal of the key phone 1 to the signal input terminal of the key phone main device 2, and connects the signal output terminal of the key phone main device 2 to the signal generator. (3) is connected, the A2 signal output terminal of the signal generator 3 is connected to the zoning signal generator 3, and the A1 signal output terminal of the signal generator 3 is connected to the time delay. A signal input terminal of the time delay unit 5 is connected to a signal input terminal of the relay driver 6, and the zoning signal generator 4 and the relay driver 6 are connected to the signal input terminal of the unit 5; The present embodiment is constructed by connecting the signal output terminal of to the signal input terminal of the broadcasting zone setting unit 7.

Referring to Figures 3 and 4 the operation of the external broadcast group control device of the key phone system configured as described above is as follows.

First, when a user presses the broadcast button and the dial of the key phone 1 in order to broadcast to a specific group, the key phone main device 2 checks the data output from the key phone 1 and then EXT-PA. Turn on the relay.

In addition, when the broadcasting zone is set in the keypad main unit 2, the signal generator 3 outputs the A1 signal as shown in FIG. 4A to the time delay unit 5 to remove noise, and sets the zone. In order to output the A2 signal as shown in FIG. 4B to the zone setting signal generator 4.

On the other hand, the time delay unit 5 inputs the A1 signal as shown in FIG. 4A to time delay (0.2 seconds), and the relay driver 6 opens the relay.

In addition, the zone setting signal generator 4 inputs an A2 signal as shown in FIG. 4B to generate a zone setting signal, and the broadcasting zone setting unit 7 shows an A1 signal as shown in FIG. 4A and an A2 signal as shown in FIG. 4B. Set the broadcast zone by inputting, and broadcast only to the group you want to broadcast through the speaker.

As described above, the apparatus for controlling an external broadcast group of the keyphone system of the present invention and a method for controlling the same are particularly unnecessarily broadcasted by dividing the broadcast zone into several groups when performing external broadcasting through the keyphone system. In addition to preventing, the broadcast can be broadcast only to a group that should listen to the broadcast, so that listeners who do not need to listen to the broadcast can perform their tasks normally.
