The present invention relates to an interphone device capable of maintaining security.

In general, an interphone is a facility for wired telephone calls throughout the premises that is not intended for trunk line connection.

The interphone is a wired communication device for premises communication that is not intended to be connected to a public line in schools, hospitals, factories, offices, and the like.

The type of interphone has a hat type and a mutual type. The hat type can be connected to one mother device and several magnetic devices to call out any magnetic device from the mother device. In this case, only the parent device can call.

The mutual expression is a combination of only a plurality of parent devices, a method that can call any other device freely from any device, and can talk freely, a couple of pairs of calls are possible without being confused with the call of the device in the call.

The prior art for the above-described intercom interphone is well represented in the Korean Utility Model Application No. 1981-0004280 "interphone device capable of maintaining security and simultaneous calls".

The technology shown in the Republic of Korea Utility Model Application No. 1981-0004280,

An interphone unit 1 consisting of n interphones having one signal line and n buttons for calling another interphone, and generating a first status signal with a line connected to a pressed button of the corresponding interphone as shown in FIG. 1. And, an oscillator 2 that emits an oscillation sound to give an initial call possible indication, and an output of the interphone unit 1 to logically combine the state signals of the first-n lines, and a latch connected to the busy line. The control signal latch unit 3 maintains a second state signal through and maintains the first state through a latch connected to a line, and the control signal is logically combined with the output of the control signal latch unit 3. According to the latch state of the latch unit 3, a signal is inputted to the line of the intercom which is in communication and the latch is reset, and the output of the control signal latch unit 3 is inputted to call and avoid Opened signal line of called intercom The oscillator 2 is connected to the signal line of the called and called interphone by switching the output signal of the interphone unit 1 by logically combining the connection unit 5 and the output of the control signal latch unit 3 with each other. The oscillation sound control unit 6 which cuts off the supply rate of the oscillation sound, which is the output of the oscillator, and supplies the initial talkable signal oscillation sound of the oscillator 2 to the other interphones.

The above technology has the advantage that simultaneous calls are possible while maintaining security, but have the following disadvantages.

First, there is a case in which the reception ring is difficult to ring in a situation where the interphone cannot be received in a conference room, a work room, an operating room, a lecture room, etc., but it is difficult for the calling user to grasp this in advance.

Second, when the user wants to talk, if the other party is already talking with another user, there is a disadvantage in that the end of the other party's call cannot be known and the user should try to make the call several times.

Third, when the user makes a call to the other party, when the receiver rings in the interphone, there is a problem that it is difficult to recognize the hearing impaired or the place where the noise is severe.

On the other hand, as a way to solve the problem that is difficult for the hearing impaired or the user in a noisy place to hear the ringtone when receiving the interphone, it is equipped with a traffic light to make the visual signal by flashing the traffic light with the ringtone The technology is well shown in Korean Utility Model Application No. 20-78-3962, the configuration is as follows.

The switch is fixed to one side of the magnetic wrought iron integrated with the rudder, which is struck by the electromagnet installed on the inner bottom of the telephone, and the battery is connected between the switch and the signal lamp mounted on the outer shell of the telephone. By the magnetic wrought iron installed on the support shaft acts like a seesaw and at the same time the intermittent pressing the button of the switch to apply the current of the battery to the traffic light so that the traffic light flashes.

The above design has the advantage that the phone is ringing and at the same time the traffic light is flashing, so that the user can immediately know the signal being signaled, but has the following problems that cannot be solved through the above design.

The above devises only a passive function of visually confirming only the ringing of a telephone ring through a traffic light, but not a function of notifying a counterpart of a user's call status or availability, and informing a difficult situation such as a lecture or a meeting in advance. There is an impossible problem.

The present invention is proposed to solve the above problems,

First, it is an object of the present invention to provide a doctor's display unit on the interphone so that a user can't make a call before the user attempts to make a call.

Secondly, when the other party is already talking with the other party, it is an object of the caller not to know the other party.

Third, an object of the present invention is to provide a convenience for the user to know in advance by providing a call display unit in order to solve the inconvenience in the situation when the user is already in the call with the other party.

In order to achieve the above object, an interphone having a call confidentiality guarantee and a pseudo display function according to the present invention is provided with a button part, a ring, and an indication part, and the interphone connected to at least one other interphone, wherein the receiver's interphone is connected to the caller's interphone. When a call is received or when a call is waiting to be received, when the receiver uses the interphone to operate a button of the button unit provided with a list corresponding to the current state indication and the pseudo signal, the current state of the receiver and the intention of the receiver input from the button unit are displayed. A doctor detecting unit transmitting a signal to the caller's interphone; And a pseudo display unit for displaying the current status of the receiver and the pseudo signal received from the pseudo detector unit in a specific color through the display unit of the caller's interphone.

Hereinafter, with reference to the accompanying drawings to describe the specific configuration of the present invention.

The interphone with the call secrecy guarantee and the pseudo display function according to the present invention is basically a general interphone including a receiver, a button unit, a ring, a display unit, a button detecting unit 10, a hook detecting unit 20, a pseudo detecting unit ( 30), the pseudo display unit 40, the ring generating unit 50, the display flashing unit 60, the busy display unit 70, the data communication unit 80, the call path forming unit 90, the interface unit 100 and The central control unit 110 and the like.

The button detector 10 detects this when the interphone user presses an interphone number to be called.

The hook detecting unit 20 detects the handset when the user lifts the handset to use the telephone.

The doctor detecting unit 30 serves to operate the doctor to communicate his or her intention to the interphone user.

The intention display unit 40 serves to display a specific interphone when the user delivers it to another interphone using the doctor detecting unit 30 to display his intention.

The ring generating unit 50 serves to generate the ring when notifying the interphone user to the ring when another interphone user wants to make a call.

The display blinker 60 serves to flash the display, that is, the LED, while the ring is ringing.

The busy display unit 70 informs which users of the intercoms connected to each other are currently busy.

When the intercom user wants to make a call and presses the corresponding button, the data communication unit 80 notifies the counterpart interphone of the intercom user and uses the doctor detecting unit 30 to display his intention. If not, it serves to inform other interphones.

When the ring is ringing, the call path forming unit 90 transmits the ring generated by the ring generating unit 50 to the speaker, and connects the voice path so that the voice signal is transmitted only to a user who wants to make a call (a user who has made a call). If another user picks up the handset, it plays a role of blocking the voice path.

The interface unit 100 may communicate data between interphones and serves to transmit voices.

(Example 1) Own Intention

The user inputs his / her current status, i.e., how to refuse to use the interphone in a conference room, counseling room, lecture room, operating room, work room, etc. The doctor detecting unit 30 transmits the present state indication and the pseudo signal of the receiver inputted from the button unit to the caller's interphone when a call is received.

When a call comes in, the receiver can enter his or her current state using the button unit or can enter the call in advance.

Accordingly, the pseudo display unit 40 of the caller interphone displays the present status indication and the pseudo signal of the receiver received from the receiver's pseudo detection unit in a specific color corresponding to the receiver's present status indication and the pseudo signal through the display unit of the caller's interphone. This allows the caller to recognize it.

That is, the display unit, that is, the color of the LED, which matches the intention of the receiver, such as a work room, an operating room, an operator waiting room, etc., is displayed, and the caller can recognize the current state of the receiver.

To this end, the button unit is provided with a number or identification plate corresponding to the present state of the receiver and an embodiment of the pseudo signal, such as a work room, an operating room, an operator waiting room, a waiting room, a finish cleaning, and the like.

Accordingly, if the receiver needs to clean the operation and prepare a new operation to the caller, it can notify the waiting personnel of the objection.

In addition, the users who have exchange intention indications can display LEDs of the same color, so that the intention indication users can transmit and receive.

Since both the receiver and the caller's interphone are provided with the pseudo-display unit 40 and the pseudo-sensing unit 30 having the same function, it is a matter of course that mutual indication is possible.

(Example 2) Ring signal display

The interphone may enable the display unit of the receiver interphone to blink in order to visually express when a call is received from the receiver intercom using the display flasher 60.

Accordingly, when the user of the interphone visually announces that a specific user wants to call, a ring signal sounds, and by blinking the LED, it can be notified even in a deaf or noisy place.

(Example 3) Currency confidentiality

When the interphone is in communication with other interphones using the call path forming unit 90, the interphone intercepts voice calls between the other interphones.

Accordingly, a call path can be formed only for a user who makes a call and receives the call, and does not form a call path even when another user picks up the handset, thereby ensuring the confidentiality of the call by allowing only the desired users to hear the call voice.

In addition, when the interphones are in communication with each other using the busy display unit 70, the busy signal may be displayed through the display unit so that the interphone user can recognize the interphone user.

According to the present invention by the configuration as described above,

First, the interphone according to the present invention includes a doctor detecting unit and a doctor display unit, so that the interphone user can perform various functions according to an appointment and a situation of expression as an alarm to another user.

Secondly, the interphone can be conveniently used even in a place where the hearing impaired or noisy by blinking the display unit of the receiver interphone to visually express the call when the call is received from the receiver intercom using the display blinker. .

Third, the interphone has an effect of protecting privacy between individuals, including a call route forming unit that blocks voice calls between other interphones when the interphones are in a call.

Fourth, the interphone has a busy display unit that displays a busy signal through a display unit so that the interphone users can recognize the interphone user when the other interphones are in a call. This will have the effect of allowing you to try the call when the call is over.
