According to another aspect of the present invention for achieving the above object, a key input unit consisting of a function key for the visitor to announce the visit bell signal or input a predetermined selection signal, a voice input unit for inputting the visitor's voice signal and the user of the room A method of processing a visit signal of a visitor provided from a door phone having an audio output unit for receiving and outputting a voice signal, the method comprising: a first step of a user indoors determining and recording an OGM; A second step of maintaining the recorded OGM voice message in a standby state in the step; A third step of transmitting the recorded OGM voice message when the doorbell signal is called from the visitor when the user is not in the room in the second step; If the ICM recording signal is input from the door phone when the user is absent in the room in the second step, ICM recording the voice signal of the visitor provided from the door phone of the door phone system using a answering phone Characterized in that it comprises a treatment method.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a door phone system using a telephone answering machine of the present invention, a visitor receives a visit bell signal, a visitor's voice signal or an ICM signal through an antenna, and the user's voice signal or a key of the telephone. A key input unit 130 composed of a transmitting and receiving unit 110 for transmitting a signal, a voice input unit 120 for inputting a voice signal of a telephone user, a function key for controlling the operation of the telephone, a message of a telephone user and a visitor message A message recording unit 140 for recording a voice signal, an audio output unit 150 for outputting a voice signal and a telephone ring signal during telephone communication between users, and a controller 160 for selectively generating each control signal according to a user's intention. A telephone main body (100); A transmitter / receiver 210 for receiving a signal from the phone main body 100 and transmitting a visitor's voice signal or a visitor's door phone key input signal, a voice input unit 220 for inputting a visitor's voice signal, and a door phone A key input unit 230 including a function key for controlling the operation of the door, a door opening unit 240 for operating an open door, and an audio output unit for outputting a user's voice signal received from the telephone 100 ( 250 and a door phone 200 including a control unit 260 for selectively generating each control signal according to a visitor's intention.

First, the key input unit 130 of the telephone body 100 includes a function key for OGM recording and an opening key for opening a door in the message recording unit 140. Therefore, in the present invention, when the user wants to record the user's own message (OGM recording) on the telephone body 100 when going out, it is possible to record the message with a function key for OGM recording in the key input unit 130. have. In addition, in the present invention, when the user goes out after the OGM recording to the message recording unit 140, when the visitor presses the door bell signal of the door phone 200 in the door recording in the message recording unit 140 (OGM recording) The received message is output to the audio output unit 250. Then, when the user is absent, the message recording unit 140 of the phone main body 100 can record the visitor's visit message (ICM recording).

Normally, the intercom function can be performed by the intercom function of a general wireless telephone, and when the door is opened, the door is opened by pressing the open key of the key input unit 130 in the telephone body 100.

When the user performs OGM recording to leave a message on the phone body 100 when going out, the process is as follows. First, when the user inputs a message (voice signal) through the voice input unit 120 after pressing the OGM function key in the key input unit 130, the message recording unit 140 under the control of the control unit 160 receives the user's message. Is recorded.

On the other hand, the key input unit 230 of the door phone 200 is provided with a function key for ICM recording and a function key for inputting a visit bell signal, the visitor is provided to the key input unit 230 when the user is absent When the bell key is input, the user's message recorded in the message recording unit 140 of the phone main body 100 is controlled by the controller 160, and the transceiver 210 of the door phone 200 is controlled by the transmitter / receiver 110. Is applied to. The transceiving unit 210 of the door phone 200 receives a message signal provided from the transceiving unit 110 of the phone main body 100 and is controlled by the control unit 260 and applied to the audio output unit 250. Then, the audio output unit 250 outputs the message of the user recorded by the message recording unit 140.

On the other hand, while the visitor enters the visit bell key of the key input unit 230 of the door phone 200 to confirm that the user is absent, the visitor is located in the door phone 200 to record a message on the phone body 100 After the ICM function key of the key input unit 230 is input and the message is transmitted to the voice input unit 220, the message to be recorded (ICM message) is controlled by the control unit 260. It is provided to the transceiver 110 of the 100. The visitor's message received by the transceiver 110 is provided to the message recording unit 140 under the control of the controller 160. Then, the message recording unit 140 records the visitor's message.

On the other hand, when the door phone 200 performs a basic function (when the user is at home) after the interphone call between the user and the visitor to the key input unit 130 of the phone body 100 to open the door When the open key is pressed, the input open signal is applied to the transceiver 210 of the door phone 200 through the transceiver 110 under the control of the controller 160. On the other hand, the control unit 260 analyzes the signal received from the transceiver 210, if the door open signal is correct and applies the door open signal to the door opener 240. Then, the door opening 240 opens the door.

On the other hand, Figure 2 is a flow chart showing the operation of the door phone system according to Figure 1, the operation process is as follows. First, if the user does not go out to the block to determine whether the user is going out in the decision block 10, the process proceeds to block P14 to maintain the telephone state of the general function, otherwise the process is determined ( Proceed to P12). On the other hand, if the user goes out without recording the voice message in the decision block (P12) proceeds to block (P14) to maintain the phone state of the general function. However, in the case of recording a voice message when the user goes out in the decision block P12, the process proceeds to block P16 to perform OGM recording and then goes out. When the execution of the block P16 is completed, the process proceeds to a block P18 to keep the OGM voice message recorded while the user is absent, and proceeds to the decision block P20.

On the other hand, the determination block P20 is a block for determining whether the visitor's visit bell signal is called when the user is out. If the visitor's visit bell signal is not called, the process proceeds to block P18 to process the loop. Do this. However, when the visitor's visit bell signal is called, the OGM voice message recorded by the message recording unit 140 is transmitted to the transmission / reception unit 210 of the door phone 200. On the other hand, the determination block P24 is a block for determining whether the ICM signal is input from the door phone 200, the process is terminated if the ICM signal is not input, and proceeds to block P26 if the ICM signal is input, the phone The ICM voice message is recorded in the message recording unit 140 of the main body 100, and the process ends.

The present invention that has performed the above process can be extended and applied to a general phone performing a response function as a door phone, by replacing the conventional door phone with wireless to open the door wirelessly, recording a simple memo when going out It is a door intercom system that can inform visitors that they are out of office and leave a message.
