Description

  The present invention relates to an interphone system including an entrance machine having a call button and an interphone master unit that detects a call from the entrance machine and makes a call via a call circuit.

In an apartment house such as an apartment, a collective entrance machine is provided at the collective entrance, and an entrance cordless handset (door phone) is provided at the entrance of the dwelling unit. This collective entrance machine has a built-in camera, and when calling a resident, a video of a visitor is displayed on a monitor of a house information panel installed in the dwelling unit (for example, Patent Document 1). In this system, you can make a call after confirming the video on the monitor, so if you do not want to talk to the person you are visiting, such as pushing sales, you do not have to make a call (if you do not make a call after a certain time, , The call is supposed to be released).
Japanese Patent Laid-Open No. 10-150499

  However, in condominiums equipped with collective entrances that do not have a built-in camera, there is a problem in that the resident cannot check the video on the monitor and cannot check the visitor without talking. Also, in condominiums that do not have a collective entrance machine, visitors make calls from the entrance cordless handset (door phone), but they cannot confirm the visitor unless they make a call as described above. There is.

  The present invention has been made to solve such problems, and an object of the present invention is to provide an intercom system in which a visitor can be confirmed without a monitor.

An intercom system according to the present invention is an interphone system including an entrance machine having a call button and an interphone base unit that detects a call from the entrance machine and makes a call via a call circuit. Then, a message output unit that outputs a message asking for an operator's name or requirement is provided.
Further, in the intercom system according to the present invention, the interphone master unit operates by detecting a call signal from the entrance machine side and detecting the call signal by the call detection unit. And a one-side communication circuit that allows only one-way communication from the interphone base unit side and captures an audio signal output from the front door side.
In the interphone system according to the present invention, the interphone master unit may further include a voice storage unit that captures and stores the visitor's voice signal via the one-side call circuit after the call button is operated, and the voice And an audio output unit that outputs an audio signal stored in the storage unit.

  In the present invention, when the call button is operated, a message asking for the name or requirement of the operator is automatically output, so that it is possible to check the visitor even without a monitor. ing.

  FIG. 1 is a block diagram showing a configuration of an intercom system according to an embodiment of the present invention. The intercom system is composed of a door phone 10 attached to the outside of the entrance of a dwelling unit, and an interphone master 20 attached in the dwelling unit, and both are connected via a telephone line T. The door phone 10 includes a call button 11, a call unit 12, a message output unit 13, a speaker 14, a microphone 15, and a call circuit 16. The message output unit 13 of the door phone 10 has a built-in storage device (not shown). In the storage device, a message for giving the operator a name, for example, a voice signal such as “Please inform me of the name” is stored, and when the call button 11 is operated, the voice signal is output to the speaker 14. . In addition, the intercom base unit 20 includes a call means 21, a call circuit 22, a switch switching unit 23, a one-side call circuit 24, a voice storage unit 25, a voice output unit 26, a speaker 27, a control unit 28, and a call detection unit 29. Yes. The one-side call circuit 24 operates by detecting a call signal by the call detection unit 29, and enables only one-way call from the doorphone 10 side to the interphone master unit 20 side. The one-side call circuit 24 is provided. Thus, it is possible to monitor the sound on the door phone 10 side.

  In the intercom system of FIG. 1, when a visitor operates and presses the call button 11 of the door phone 10, the calling unit 12 outputs a call signal to the interphone master 20 side via the telephone line T. In intercom base unit 20, call detection unit 29 detects the call signal and outputs the detection signal to control unit 28. When the detection signal is input, the control unit 28 switches the switch switching unit 23 to the terminal b side to connect the communication line T to the one-side communication circuit 24 side. In addition, when the call detection unit 29 detects the call signal, the call detection unit 29 outputs a call sound (for example, a chime sound) from the speaker 27 to notify that the visitor is coming. Thereby, the resident can recognize that the visitor is coming to the entrance.

  On the side of the intercom 10, the message output unit 13 outputs a voice signal stored in advance, for example, a message such as “Please tell me your name” to the speaker 14 in response to the operation of the call button 11. Ask for the name and ask them to give their name. The guidance by the message output unit 13 may be displayed on a display (not shown). Here, when the visitor calls his name “I am Nagata”, for example, the voice is converted into a voice signal by the microphone 15 and transmitted to the interphone master 20 side via the call circuit 16 and the call line T. On the intercom base unit 20 side, the audio signal from the door phone 10 is taken in and stored in the audio storage unit 25 via the terminal b of the switch switching unit 23 and the one-side communication circuit 24 (for example, stored for 10 seconds or more). Note that the voice storage unit 25 is activated by a detection signal from the call detection unit 29. The audio output unit 26 incorporates a timer (not shown), and alternately outputs a chime sound signal and an audio signal stored in the audio storage unit 25, for example, every few seconds. The sound “is” is output alternately. At this time, the interphone master unit 20 and the door phone 10 are connected via the one-side call circuit 24, and an audio signal or the like from the interphone master unit 20 side is not transmitted to the door phone 10 side. The 10-side visitors will not be informed of the presence of residents.

  As described above, since the chime sound and the voice “I am Nagata” are alternately output from the speaker 27, even if the resident is away from the interphone master 20 and misses the first voice of the visitor, And know who came. In this way, in this embodiment, it is possible to know who the visitor is before starting a call, so that there is no need for a partner such as a push sale.

  When the visitor wants to make a call with a friend or the like, the resident picks up the call means 21 including, for example, a handset. Thereby, the control unit 28 detects it, switches the switch of the switch switching unit 23 to the terminal a side, and connects the call circuit 22 to the call line T. In this way, the interphone master unit 20 and the door phone 10 can make a call via the respective call circuits 22 and 16.

  In the above description, the example in which the message output unit 13 is provided on the door phone 10 side has been described. However, the message output unit 13 is provided on the interphone base unit 20 side, and operates by detecting the call signal of the call detection unit 29 to send a message. It may be transmitted to the door phone 10 to guide the visitor to give his name. In the above description, an example of a door phone as an entrance machine has been described. However, in the present invention, the present invention is similarly applied to an interphone system that uses a collective entrance machine as an example of an entrance machine when installed in an apartment or the like. The

  Note that the message output unit 13 may output “Please let us know your name and then press the call button”. In this case, the voice storage by the voice storage unit 25 starts recording by the first call button operation, stops recording by the second call button operation after the name is given, and the voice is chime sound When the output is alternated, useless time without sound can be eliminated. Further, the message output unit 13 outputs a message for giving the name of the operator, but a message for asking a message such as “What is your business?” May be output.

It is a block diagram which shows the structure of the intercom system which concerns on embodiment of this invention.
