The present invention relates to a door phone gender device which is coupled between a door phone and an interphone so as to facilitate the realization of a door phone system of a new function through replacement of a door phone, will be.

Generally, the door phone system is composed of a door phone installed outside the door and an interphone installed at the house, installed in every place where the intermediate medium including the inside / outside of the house or the inside / outside of the house exists, It is possible to visually check the outside situation of the door and the voice communication with the outside from the inside (or the house).

In recent years, a door phone system has been developed and is in commercial use, in addition to confirming the situation outside the door through the interphone in conjunction with the door lock, as well as controlling the opening and closing of the door. That is, as the technology develops, a door phone system in which various functions are provided has been developed, and the development of a door phone system in the future can be said to be planned.

However, the door phone system is generally fixedly installed at the outside of the building and at home, and a new door phone system configured to provide the corresponding function should be installed in order to receive new functions.

In particular, since the interphone installed in the house is fixed to the house wall and the public buildings such as the apartment are configured to communicate with the guard room or the management room, it can be considered that the door phone system can not be re-installed practically for public buildings .

Accordingly, there has been a proposal for replacing only a door phone which is relatively easy to install, using a conventional interphone as it is difficult to install.

However, in the door phone system, the door phone is configured to be powered by the interphone, and in the case of the conventional door phone system, the door phone is configured to be operated by receiving AC power from the interphone Considering that currently developed door phones are generally configured to operate from a DC power source, it is difficult to install and operate only a new door phone.

1, the conventional interphone 1 and the door phone 2 are connected in a four-wire manner or the interphone 1 and the door phone 2 are connected to each other by two (B) and is configured to transmit a signal. That is, the signal transmission modes of the interphone 1 and the door phone 2 are different according to the installed door phone system. When the door phone 2 is replaced, the door phone 2 and the conventional interphone 1 It is necessary to match the signal transmission format between the mobile terminal and the mobile terminal. In order to produce one door phone 2 model, various kinds of door phones 2 corresponding to the signal transmission type of the conventional interphone 1 must be produced. Therefore, the production cost of the door phone 2 is increased .

The method according to claim 1,
The signal processing module includes an interphone signal line sensing unit for sensing an interphone connection port to which an interphone signal line is coupled, a door phone signal line sensing unit for sensing a door phone connection port to which a door phone signal line is coupled, A first switch for setting a bypass path and a bypass path for a signal provided from the interphone signal receiving unit, an interphone signal to be inputted, and a power supply provided from the power supply module, A door phone signal receiving unit for receiving a door phone signal provided from the door phone connection port, setting a modulation / demodulation path and a bypass path for signals provided from the door phone signal receiving unit, A second switch for providing an input door phone signal to an intercom connection port A modulation and demodulation unit for modulating or demodulating an interphone signal and a door phone signal provided from the first and second switches and outputting the modulated or demodulated signal to the interphone signal providing unit and the door phone signal providing unit, A signal line coupled to the interphone and the door phone is determined based on the sensing signal provided from the line sensing unit and the door phone signal line sensing unit to set the first and second switch paths and the modulation or demodulation of the modulation / And a control unit configured to set a processing path to perform signal transmission processing between the interphone and the door phone. The method according to claim 1,
The signal processing module routes the signal received from the interphone and the door phone to be bypassed when the number of interphone signal lines connected to the interphone connection port and the number of door phone signal lines connected to the door phone connection port are the same, And performs modulation and demodulation processing on signals received from the interphone and the door phone when the number of interphone signal lines and the number of door phone signal lines are different from each other. The method of claim 3,
When the number of interphone signal lines connected to the interphone connection port is greater than the number of door phone signal lines connected to the door phone connection port, the signal processing module performs signal modulation processing on the interphone signals and provides the interphone signal signals to the door phone , The door phone signal is subjected to signal demodulation processing and provided as an interphone,
When the number of door phone signal lines connected to the door phone connection port is larger than the number of interphone signal lines connected to the interphone connection port, the interphone signal is demodulated and provided to the door phone, And performs signal modulation processing to provide the signal to the interphone. The method according to claim 1,
Wherein the power module converts an AC type 110V to 220V power supplied from the outside into a 9V to 12V power supply (Vcc) of 9-12V DC type and outputs the converted power.
