When called from the other party, the relay IC is operated by the controller IC ₃ to make an interphone call with the other party. The operation relationship of the present invention configured as described above will be described with reference to FIGS. 5 to 7.

First, the intercom (PH) control room as shown in FIG. 3 as well as the security office intercom gakdong (I: 1I ~ NI) and by generation of the video intercom gakdong _{(H: 1H 1 -1H n,} 2H 1 - 2H n, NH 1 - When the necessary driving power is applied to each control unit IC ₁ -IC ₃ through the power supply unit of NH _n ), the operation of the interphone communication function will be described with each interphone PH (I) (H) operating normally. First, the guard room call in each household and the intercom call method with the guard room, the guard room call button (AB ₁ ) connected to the input unit (IN) of the control unit IC ₁ of the household interphone (H) as shown in Figure 4a When pressed, this signal is processed by the control unit IC ₁ of the generation interphone H and sent to the control line through the communication port RS-422. At the same time, the control unit IC ₁ energizes the generation interphone relay IX through its output unit OUT and connects the generation interphone unit through its contact a IXa to the call line.

When the guard room call signal of the household interphone H transmitted through the control line is applied to the consent guard room interphone I to which the household interphone H belongs, the control unit IC ₂ of the guard room interphone I is connected to the 4b. As shown in the figure through the output section (OUT) of the lamp for the household display (D ₁ -D _n ) for calling the guard room at the same time while ringing the bell through the buzzer (B ₂ ).

In the guard room interphone I, as shown in FIG. 5, the indication lamps (P: P ₁ -P _{n in} FIG. 4b) of each guard room and management room are arranged in sequence, and The display lamps (D: D ₁ -D _n in FIG. 4B) are arranged layer by layer. Accordingly, in the guard room of the household where the guard room call button (AB ₁ ) is pressed, the buzzer (B ₂ ) sees the indicator lamp (D ₁ -Dn) turned on by a ring tone or lighted, and the guard room manager recognizes that the guard room is calling the guard room. do.

At the same time, the control unit IC ₂ of the guard intercom I interlocks the relay LX for generation through its output unit OUT, shorts its contact a LXa, and is connected to the generation intercom H at the same time. Open the telephone line. Therefore, the closed circuit of the telephone line is connected to the interphone by the guard room call button AB ₁ pressed on the household interphone (H) with the guard intercom (I), so that the intercom call is possible, and this call is made of the household interphone (H). While the guard room call button (AB ₁ ) is selected, it is possible to talk to the guard room, and if the guard room call button (AB ₁ ) is released after the call is completed, the control unit (IC ₁ ) of the intercom call line between the household and the guard room is his output unit. The generation interphone relay IX that was driven through (OUT) is turned off, and the control unit IC ₂ of the guard intercom I is of course the generation relay LX that was driven through its output unit OUT. Turn off the display lamp (P ₁ -P _n ) and the generation display lamp (D ₁ -D _n ) of the copper. Also, for example, the guard room calls the desired household and the interphone communication method with this household _first selects the button (TB _1- TB _n ) of the household to be called from the guard intercom (I) as shown in FIG. When pressing (CA), the control unit IC ₂ of the guard intercom I through the input unit 1N is selected as well as the agreement display lamps P ₁ -P _n : P to which the calling household belongs via its output unit OUT. The household display lamp (D ₁ -D _n : D) is turned on to indicate the household to be called, and the household relay (LX) is excited, and through the contact aX (LXa) of the intercom part of the guard intercom (I) Closed circuits are formed between communication lines.

At the same time, the control unit IC ₂ of the guard intercom I transmits the call signal of the selected generation to the generation control line through its communication port RS-422. At this time, if the generation call signal of the guard intercom I transmitted is applied to the interphone H of the household, the control unit IC ₁ of the calling generation interphone H is connected to its output unit OUT as shown in FIG. The interphone relay IX is excited to close its a contact IXa.

Accordingly, the selected generation intercom H can be interphoned with each other through the microphone MiC and the speaker SP between the intercom unit, the guard intercom I and the generation intercom H connected to the call line. .

Here, in the state where the call button CA of the guard intercom I is selected, the household interphone H excites the broadcast relay AX through the output OUT of its control unit IC ₁ to contact its a contact AXa. When the short circuit is intercepted, the bell signal of the interphone is transmitted through the speaker SP, and the ringing sound is ringed. This ringing tone is made when the caller of the household interphone H turns on the guard room call button AB ₁ of his control unit (IC _1). By turning off the broadcast relay (AX) of the output unit (OUT) to stop the ring tone. Thereafter, when the guard room and the household call are released from the guard room call button AB ₁ of the household interphone H as described above, the controller IC ₁ turns off the household intercom relay IX by the control unit IC ₁ and the call line and the intercom. The a contact point IXa of the relay is opened between the parts so that the interphone call circuit is cut off, and the control unit IC ₂ of the guard intercom I is connected to the generation relay LX through its output part OUT as well as the corresponding. The motion display lamps (P ₁ -P _n ) and the generation display lamps (D ₁ -D _n ) are turned off. In addition, as an example, the intercom intercom communication method of the same household, such as the household, first press the guard room call button (AB ₁ ) in the intercom (H) of the household to be called, the guard room of the corresponding call.

Pressing the guard room call button (AB ₁ ) in the intercom (H) of the household to be called in the guard room of the corresponding agreement is operated as described in the above example (operation description when calling the guard room in the household) the guard intercom (I) and once closed circuit of a telephone line are formed.

At this time, when the intercom communication between the household intercom (H) and the guard intercom (I) of the corresponding building with the closed circuit of the telephone line is exchanged, the household required by the household to be called requires a different household for the same consent. Once the guard room manager presses the standby button LB connected to the input unit 1N of the control unit IC ₂ of the guard room interphone I as shown in FIG. 4 (b), the guard room interphone is connected by the standby button LB signal. In the control unit IC ₂ of (I), the household to be called is put on standby once, and in this state, the household selection button (TB _1- TB _n ) of the household desired to be called is pressed, and then the call button (CA) Pressing, the control unit IC ₂ of the guard room interphone I is made as described in the above-described operation example (generation call and interphone communication operation description in the guard room). At this time, when the household of the other party is called, the guard room manager presses the call button (CB) connected to the input of the control unit (IC ₂ ). In this operation, the control unit IC ₂ of the guard intercom I transmits a control signal for intergenerational communication to the control line for generation through the communication port RS-422, and the signal is transmitted to the intercom (H) of the generation for which the call was desired. ) Is applied to the control unit IC ₁ of the household interphone H of the other party and controlled to communicate with each other.

Thus, mutually between the three currencies stood so drop the guard call button (AB ₁₎ was pressing the guard call button (AB ₁₎ is installed on the intercom (H) of each generation to do the interphone communication, press both currency amounts generations The related functions are reset to the initial state, and the call is disconnected, and at the same time, it is also reset to the call waiting state with the selected guard intercom (I). Also, as an example, the guard room and the intercom communication method of the guard room and the other wing, as shown in FIG. 4b, pressing the corresponding wing select button IB ₁ -IB _n that is connected to the input unit IN of the control unit IC ₂ . Next, when the call button CA is pressed, the control unit IC ₂ of the consent guard intercom I to be called outputs a control signal for designating a call call to the generation control line through its communication port RS-422. Subsequently, the control intercom (I) control unit IC ₂ of the corresponding call center lights up the motion display lamps D ₁ -D _n , which are named through the output unit OUT, by the designated control signal on the control line. ₂ ) to indicate that it is calling.

At the same time, the control unit IC ₂ of the guard intercom I, which is called, excites the relay for generation and management room LX (MX) through its output unit OUT, and calls it through its a contact LXa (MXa). A communication line is connected between the guard intercom I and the guard interrogation I to switch to the intercom call enabled state.

When the call button CA connected to the input unit IN of the guard intercom I called in such a state is pressed, communication of the guard intercom I called again through the control line by the control unit IC ₂ thereof. It is transmitted to the port RS-422, and through the output part OUT of the control part IC ₂ thereof, the generation and management room relays LX (MX) are excited as described above, and their contact aLXa (MXa) is removed. Connect the intercom portion of the name guard intercom (I) to the telephone line.

In such a state, intercom calls are made through the microphone MiC by pressing the call buttons CB which are commonly connected to each other. After completing the call, the call buttons CB of the guard room interphone I of each building are released as described above. As with the operation, the interphone call function is reset and is switched to the initial interphone call waiting state. In addition, as an example, the intercom communication method with the households different from each other in the household, pressing the guard room call button (AB ₁ ) of the household interphone (H) to be called _first , the above-described operation (operation at the guard room call in the household and the household and the corresponding guard room The intercom communication operation with) and the call line closed loop formation and the standby button (LB) operation is made the same, and then the guard room manager in the guard room interphone (I) belonging to the household intercom (H) to be called Press the select button (IB ₁ -IB _n ) of the corresponding building belonging to the other household desired by the household, and then press the call button (CA). ₂ ) outputs the control signal corresponding to the designated building. At the same time, in the designated security guard intercom I, the corresponding display lamps D ₁ -D _n from the call center connected to the output unit OUT through its control unit IC ₂ light up, thereby turning on the buzzer B ₂ . It tells it to be called. Subsequently, the operation is made in the same manner as described above in the intercom communication function between the guard intercom I of the call dong and the guard intercom I of the Homyung dong (intercom communication between the guard and the other guard). In the security guard intercom (I) called by pressing the waiting button (LB) connected to its input (IN) to wait for the security guard intercom (I) once called. In the waiting operation, the same operation is performed as in the above-described operation example (calling the other consent generation from the generation and interphone call operation).

In the consent guard room interphone I called in a state where the guard room of the named consent is held in the above manner, the household selection button TB ₁ -TB for selecting the required household connected to the input unit 1N of the control unit IC ₂ . _n ), and then presses the call button CA. This operation is performed as described in the above-described operation example (operation call in the guard room and interphone communication operation description). Then, after calling the household called again in the agreed security guard intercom (I) and pressing the call button (CB), the control unit (IC ₂ ) of the guard intercom (I) in each building controls the available state between households and simultaneously The intercom call between the households can be made by relaying the guard intercom I of the household. In this case, the intercom call is made by pressing the guard call button AB ₁ of the household interphone H. Since the call-off operation also releases the guard room call button AB ₁ from each other's household interphone H as described above, the display lamps P ₁ -P _n of the household designated in each security guard intercom I ) Is activated and the available state is reset to the initial state to complete the call.

Also, for example, the guard room call and intercom call in the guard room, or the guard room call and intercom communication method in the management room, as shown in Figures 3 and 4b, c, for example, if you want to call the management room in the guard room intercommunication first, As shown in (b) of FIG. 4, when the control room selection button PB connected to the input unit 1N of the guard room interphone I is pressed, and the call button CA is pressed, the control unit IC ₂ displays its output unit OUT. The control relay (MX) is energized and connected to the telephone line and the intercom portion of the guard intercom (I) through its contact a (MXa).

At the same time, when the removal signal designating the management room is output to the control room control line through the communication port RS-422 of the control unit IC ₂ , the communication of the management room interphone PH is performed as shown in FIGS. 4C and 6. The control unit IC ₃ through the port RS-422 confirms the state in which the interphone selection switch 1H is currently set through its input unit 1N, and if the interphone selection switch 1H is selected, its output unit ( The motion display lamps (PP ₁ -PPn) corresponding to the control signals transmitted from the guard room are turned on at the same time, and various interphone relays (MX) are excited, and through the a contact point (MXa), the management office interphone (PH) Connect between intercom part of telephone and call line.

In such a state, interphone communication is performed through the microphone of the guard intercom (I) or the management intercom (PH), and the voice signals between the call lines are transmitted through each speaker SP. If the call buttons are mutually released as described above, the interphone call function is completed and the interphone call is waited at the same time, and the indication lamp (PP ₁ -PPn) is also turned off to intercom between the guard room and the management room. The call ends.
