Description

Communication state recognition device of facsimile mixed-use telephone and method thereof

The present invention provides a communication system in which a parallel telephone is connected to a facsimile or a facsimile-mounted first telephone and a second telephone installed separately from a non-visible position in common with one trunk line, wherein any one telephone is in a call. When the other telephone is to be used, the present invention relates to an apparatus and method for recognizing a call state of a facsimile mixed-use telephone that can improve communication service between users by audibly notifying a later user that a line user is busy.

In general, facsimile machines that can transmit and exchange document information quickly and remotely using a telephone line can be used with a telephone according to a user's choice. Such a facsimile phone is a relatively small office or home. It is widely used in Edo.

Moreover, even in small offices and homes, when a large number of telephone users are used, a technique of using another telephone in parallel with a trunk line of a facsimile-based telephone is common.

That is, as an example in the above case, as shown in FIG. 1, a line for switching a line to allow communication between a facsimile or a telephone with an outside according to a user's selection on one trunk line L ₁ (L ₂ ). With the switching unit 10, the trunk line L ₁ (L ₂ ) are alternately connected to correspond to the selected line through the circuit switching unit 10 to transmit and receive document information through the facsimile 20, or Or, it is configured to make a call with the outside through the first and second telephones (30, 40).

In addition, the user uses the trunk line L ₁ (L ₂ ) as the telephone 30, 40 through the line switching unit 10 in the operation relationship made by the parallel connection method of another telephone to the facsimile-based telephone. If it is selected to use the facsimile 20 is limited, on the contrary, if selected to use the facsimile 20, the trunk line (L ₁ ) (L ₂ ) connected to the telephone (30) 40 to the facsimile (20) The connection is executed to limit the use of the telephones 30 and 40.

In the case where the trunk line L ₁ (L ₂ ) through the rotation switching unit 10 is selected to the telephones 30 and 40 and is intended to be used only as a telephone, when the first telephone 30 is busy, the second telephone 40 is operated to maintain the mute state as if no operation is made even when the handset and the receiver are lifted.

However, when another telephone is connected in parallel to such a facsimile-based telephone, when each telephone is in a visually identifiable position with each other, visual confirmation between the users can reduce unnecessary actions for a call attempt. However, if, for example, the second telephone connected in parallel with the first telephone is located in a different place, that is, a place that cannot be visually confirmed, the other telephone may not operate at all when the telephone is picked up. As a result of the operation being kept closed, the telephone user who is in the closed tone state is forced to hold the LOOP due to the operation of another telephone or the failure of the telephone itself. I can't see for sure Uh cumbersome inconvenience of whether you use the phone in handageona check whether the fault of the phone, or any one should check each time followed each time.

Therefore, the present invention enables a later user to easily recognize that the user is in a call even when a plurality of telephones connected in parallel are installed at a location that cannot be visually confirmed, thereby improving communication service and attempting to call each other. It is an object of the present invention to provide an apparatus and method for recognizing a call state of a facsimile mixed-use telephone capable of reducing unnecessary behavior and solving general problems such as a confirmation procedure according to a closed sound.

That is, the line switching unit 10 energizes the trunk lines L ₁ and L ₂ with the first and second telephones 30 and 40 through the facsimile 20 or the modem A according to a user's selective manipulation. It is configured to be.

In addition, the modem A includes a plurality of hook switch detection units 50 and 60 that monitor whether each of the first or second telephones 30 and 40 is used, and the plurality of detection units 50 and 60, respectively. Logic matching circuit 70 for matching each signal output from the < RTI ID = 0.0 >) < / RTI > The voice information storage unit 80 outputs the voice information to the first and second telephones 30 and 40, or waits for the voice information in a storage state, and the voice information output from the voice information storage unit 80. The first and second telephones 30 and 40 are configured by interconnecting the voice signal transmitter 90 for modulation and transmission so as to be recognized.

In detecting whether the first or second telephone is used, the on / off signal of the hook switch installed in each telephone is used as an input source.

The hook switch detection unit 50, 60 is characterized in that the input source is the on / off signal of the hook switch installed in each telephone in detecting the use of the first or second telephone. Monitor the on / off state of the hook switches of the second telephones 30 and 40 so that the black switch of each of the telephones 30 and 40 is turned on (in a call state) and the hook switch is turned off ( In the case of a waiting state), a 'high' signal is configured to be output, which may be one secured in multiple channels in proportion to the number of telephones, or a plurality of telephones corresponding to the number of telephones.

In addition, the logic sum-negative circuit unit 70 is a 'high' when both outputs of the hook switch detection unit 50, 60 is a 'low' signal, either of the two outputs of the hook switch detection unit 50, 60 When one output is 'low' or both 'high' signals, it is characterized by consisting of a NOR gate that outputs a 'low' signal.

In addition, the voice information storage unit 80 is a nonvolatile memory in which a voice message indicating that a melody or a call is stored, which outputs the stored voice information only when the output of the logic matching circuit 70 is 'high' and outputs the same. If the 'low' is characterized in that the voice information is configured to wait in the recording state.

In addition, the voice signal transmission unit 90 is characterized in that the primary side, and the secondary side is composed of a transformer wound in a coil, the primary side is the output of the voice signal storage unit 80, and the secondary side is induced from the primary side It is configured to be interconnected so that the voice signal is applied to the first and second telephones 30 and 40 through the hook switch detection unit 50 and 60.

On the other hand, Figure 3 is a block diagram showing a call state recognition guide device of the facsimile hybrid phone as a second embodiment of the present invention.

Switching means for changing the line by the user's selection in this embodiment configuration, call means for allowing the trunk line to be connected to the facsimile or the first and second telephones to make a call with the outside; A plurality of hookswitch detection means (50) and (60) for monitoring the use of two telephones (30) and (40), respectively, and modulating the voice information to be recognizable by the first and second telephones (30) and (40), In the voice signal transmission means 90 to be transmitted, the configuration is the same as that included in the modem A of the first embodiment shown in FIG.

Specifically, in the second embodiment, the signal discrimination output from the hook switch detecting means 50 and 60 and the means for determining whether to output a melody or a voice signal informing that the user is busy are determined according to the determination of the signal. It is different from the microprocessor M which controls overall control.

According to the present invention, the microprocessor (M) basically discriminates the voice information memory which stores the voice message information indicating that a melody or a call is in progress, and the signal output from the hook switch detection unit (50) (60). There is a built-in program memory for determining and executing audio information and a digital-analog converter for converting the output audio information into an analog signal.

This embodiment is preferably applied to a facsimile provided with a voice guidance service function for an abnormal state in operation.

4 is a flowchart illustrating a call state recognition operation of a facsimile mixed-use telephone according to the present invention.

That is, the method of the present invention is a unique function of the telephone in the idle step (M ₁ ) that the first and second telephone (30, 40) is switched to the trunk line (L ₁ ) (L ₂ ) to be able to talk to the outside The inspection step (M ₂ ) (M ₃ ) to check the general operating state with respect to, whether the first and second telephone (30, 40) of the first and second telephone (30, 40) from the hook switch detection unit 50, 60 When it is determined by the determination step (M ₄ ) ( ₅ ) of checking and simultaneous use of the first and second telephones (30, 40), the voice information transmitting step (M ₆ ) (notifying that both users are in a call) ( M ₇ ) (M ₈ ).

5 is a truth table showing the input / output signals of the logic matching circuit section 70 applied to the apparatus of the first embodiment, which will be referred to below.

In the operation relationship according to the first embodiment of the apparatus of the present invention configured as described above, the trunk line L ₁ and L ₂ are connected to the telephone side through the line switching unit 10 by a user's selective operation as shown in FIG. When the handset (handset) of the first and second telephones 30 and 40 is lifted in a state in which the telephone is available to the outside, the hook switch (not shown) is turned on and is switched to a available state while the signal is 'low'. When the handset is put down, the hook switch is turned off and goes to the standby state, and outputs a 'high' signal.

The first and second telephone detectors 40 and 50 of the modem A, whose signals are output from the hook switches of the first and second telephones 30 and 40, are the same as the input signals. Operate to output a signal (see FIG. 5).

In this state, if only the first telephone 30 is in a call, the first telephone detector 50 is 'low' and the second telephone detector 60 is outputting a 'high' signal, so that the gate The configured logic sum negative circuit unit 70 outputs a low signal as described in the truth table of FIG.

Accordingly, since the voice information storage unit 80 does not satisfy the condition for transmitting the voice information, the voice information storage unit 80 may be inoperative to keep the voice information in a standby state.

This is the same as the above operation even when only the second telephone 40 is in a call is limited to output voice information.

However, when the handset of the second telephone 40 is lifted while the first telephone 30 is in a call, both the first and second telephone detectors 40 and 50 output a 'low' signal. The logic sum negating circuit unit 70 using the signal as an input source outputs a 'high' signal.

At the same time, since the voice information storage unit 80 is in a relationship that satisfies the condition for transmitting the voice information, the voice information storage unit 80 transmits the voice information indicating that the voice information is in the call.

Therefore, the voice information output from the voice information storage unit 80 is modulated and transmitted to a signal suitable for the first and second telephones 30 and 40 (the sign language unit) through the voice signal transmission unit 90, and then modulated. The voice signal is transmitted to the user of the first and second telephones 30 and 40 again through the first and second telephone detectors 50 and 60 to recognize that the user is a pre-user.

In addition, the second embodiment and in the operating relationship of the inventive method relating to this embodiment, first trunk line by a user of the selective operation as shown in Fig. _{3 (L 1) (L 2} ) the circuit switching section of the device of the present invention ( 10) an operation to be connected to the telephone side through the outside to enable telephone use with the outside; When the handset (handset) of the first and second telephones 30 and 40 is picked up, the hook switch (not shown) is turned on and is switched to the available state, and outputs a 'low' signal, and the handset is dropped. On the contrary, the hook position is turned off and is switched to the standby state to output a 'high'signal; The same operation as that of the first and second telephone detectors 40 and 50 or the first embodiment outputs the same signal as the signal generated from the hook switches of the first and second telephones 30 and 40. .

In the microprocessor M of the facsimile 20 related to this, as shown in FIG. 4, the first and second telephones 30 and 40 are connected to the trunk lines L ₁ and L ₂ to communicate with the outside. In the idle step (M ₁ ) is possible to perform the inspection process to check the overall operating state of the unique function of the phone repeatedly (M ₂ , M ₃ ).

In such a state, the microprocessor (M) sequentially determines the output signal for whether the corresponding telephone is used through the first and second telephone detectors (50, 60) (M ₄ , M ₅ steps). Of the two telephones 30 and 40, the first and second telephone detectors 50 and 60 are respectively used when only the second telephone 40 is used without using the first telephone 30 or when the reverse of the above example is used. 'High' / 'Low' and 'Low' / 'High' signals are output through.

Accordingly, the microprocessor (M) recognizes that only one of the two telephones is being used or not to be used, so that the microprocessor (M) does not transmit the voice information of its own voice information memory.

On the other hand, in other cases, that is, when the handset of the second telephone 40 is lifted while the first telephone 30 is in a call, or vice versa, the first telephone 30 is in the state where the second telephone 40 is in a call. When the handset is heard, the first and second telephone detectors 40 and 50 both output a 'low' signal.

At the same time, the microprocessor (M) recognizes that both phones are used when the outputs of the first and second telephone detectors 40 and 50 are determined to be 'low' signals (M ₄ and M ₅ steps). It drives the voice information memory that holds the controls so as to transmit the voice information indicating that a _{call. (M 6, M 7,} M ₈ steps)

Accordingly, the 'voice information informing that the call is in progress' transmitted from the voice information memory of the microprocessor M is a signal suitable for the first and second telephones 30 and 40 (the signing unit) by the voice signal transmission unit 90. The modulated voice signal is transmitted to the user of the first and second telephones 30 and 40 through the first and second telephone detectors 50 and 60, and then the user himself. Will be recognized.

In relation to the present invention described above, in the description of the first and second embodiments, the means for notifying that the user is in a call has been described so that both the first and second users can recognize the voice message, but the present invention is not necessarily the same. It can also be used as an acoustic means such as melody.

In addition, importantly, the apparatus of the present invention can be applied to a communication system to be newly installed, as well as to a communication system secured by a user by using a modem A independently.

As described above, the present invention allows the user to easily recognize that the line user is in a call even in a state where a plurality of telephones connected in parallel are installed at a position that cannot be visually confirmed, thereby improving the service of the parallel connection communication system. In addition, in terms of efficient phone operation, unnecessary actions on the user's call attempt can be reduced, and the general problems such as the user confirmation procedure according to the closed sound can be solved.
