Abstract

PURPOSE:To make communication with a transmitting partner after confirming the partner through video, by utilizing a voice transmitting communication means and optical fiber cable. CONSTITUTION:When the push-button switch 3 of a slave device 1' is depressed, a buzzer sound is generated at a receiver 5 through an electric circuit 11 for transmitting voices, circuit 6, and another electric circuit 11 and an answer request from the device 1' is transmitted to a host device 2'. At the device 2' the video of the transmitter can be confirmed by receiving the video taken by the lens of a video monitor 8 attached to the device 1' through a video transmitting mechanism 12, optical fiber cable 7, video receiving mechanism 12', and video screen 9 before picking up a receiver 5. Therefore, answers corresponding to transmitters can be transmitted to the device 1' through the receiver 5.

Description

[Detailed Description of the Invention] (Technical Field) The present invention provides an intercom system, in particular, not only a means for transmitting and communicating audio, but also a means for transmitting and receiving images that allows the receiving side to monitor the image of the other party on the receiving side. Regarding intercom system.

(Prior Art) A conventional intercom device includes a microphone and a speaker for mutually transmitting audio to a transmitting/receiving image device.Hereinafter, a conventional example will be described with reference to FIG. 1.

A conventional intercom device includes a parent/child device 2, 1, a push button switch 3 for making a call from the child device 1 to the parent device 2, a speaker 4 for inputting/outputting audio to/from each device,
It is composed of a microphone 10, a receiver 5, and a line 6 for transmitting audio signals.

In such an intercom device, the call switch 3 of the child device 1 sounds the call buzzer of the parent device 2,
When you pick up the handset 5 of the parent device 2, the microphone 10 of the child device 1. The audio mutual communication circuit between the speaker 4 and the handset 5 on the parent device 2 side is activated, allowing mutual conversation.

In other words, since the intercom device shown in Fig. 1 is configured as a single-function device exclusively for voice communication between the parent and child devices, it is possible to tell who is on the other end depending on the content of the words input from the child device (sending side). Therefore, it is necessary to constantly judge whether the slave device is the transmission destination (
(Objective of the Invention) The object of the present invention is to provide an intercom system that allows a caller to make a call after confirming the sender's partner using video.

(Structure of the Invention) According to the intercom system of the present invention, there is obtained an intercom system characterized by having a voice transmission communication means and a video transmission and reception means using an optical fiber cable.

(Example) Next, an example of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a block diagram of an embodiment of the present invention, and FIG. 3 is a diagram showing its audio/video transmission route. In the figure, 1' is a child device (transmitting side), 2' is a parent device (receiving side), 3 is a push button switch, 4 is a speaker, 5 is a receiver, 6 is an audio transmission line, and 7 is an optical fiber for video transmission. Cable, 8 is video monitor, 9 is video screen, 10 is microphone, 1
1 is an electric circuit for audio transmission, 12 is a video transmission mechanism, 12'
is the image receiving mechanism.

Now, in FIG. 3, when the push button switch 3 of the slave device (transmission side) 1' is pressed, the audio transmission electric circuit 11 and the line 6 are pressed.
, a buzzer sound is generated at the receiver 5 through the electric circuit 11, and a response request from the child device 1' is transmitted to the parent device (receiving side) 2'. As a result, when the handset 5 of the parent device 2' is picked up, a state is established in which mutual voice communication can be performed between the two devices.

In this embodiment, before picking up the handset 5, the image displayed on the lens of the image monitor 8 attached to the slave device 1' is sent to the image transmitting mechanism 12, the optical fiber cable 7, and the image receiving mechanism 12'.
, is received on the parent device 2' side through the video screen 9, the sender's identity can be confirmed on the parent device 2', and a response depending on the recipient can be transmitted to the child device 1' through the receiver 5.

(Effects of the Invention) As explained above, the present invention has the effect that only the necessary calling party can be appropriately determined and a call can be made using the Eirin monitor.
