The present invention relates to a converter system that can be used as an IP phone such as a VoIP phone or a RoIP phone without replacing a terminal itself such as an existing interphone or a radio by connecting a call after assigning a virtual phone number.
Description
The present invention relates to a converter system, and more particularly, to an interphone for converting a voice signal generated from an interphone, an intercom, a walkie-talkie, a radio, or the like, into a digital signal and generating or receiving a voice signal. The present invention relates to a converter system that can be used as an IP phone such as a VoIP phone or a RoIP phone without replacing a terminal itself such as an existing interphone or a radio by connecting a call after assigning a virtual phone number.
In general, an interphone or intercom is a wired telephone device used in various areas of a building and used for premises communication, and voice signals are transmitted / received between analog callers using an analog method, and a plurality of interphones or intercoms are connected to relay devices. The call was made by selecting a fixed identification number of each interphone or intercom.
In addition, the radio is a radio call device that allows voice calls between radio bearers who are separated from each other in the outdoors where radio signal transmission is less likely to be interrupted. Only through the voice signal was sent and received.
Such conventional interphones, intercoms or walkie-talkies (hereinafter referred to as interphones) have been planned and installed or provided for transmitting and receiving voice information in a limited area. Recently, various multimedia data as well as voice information can be transmitted and used. There is a problem that it is not easy to expand to IP phones (Internet Protocol Phone), which is an increasing new communication means.
Accordingly, when using an IP phone in a communication environment that has been conventionally constructed to use an interphone, it is difficult to change a relay device that connects each other, such as a plurality of interphones, and Internet-based communication to be changed. Since it is necessary to replace all the interphones with a new VoIP phone or a RoIP phone that can transmit and receive data such as voice in the environment, the replacement cost of interphones is very expensive, and the connection facilities between the replaced interphones and the relay devices must be completely replaced. There was a problem that the cost is also greatly increased.
As such, in order to apply the internet-based communication environment to outdoor construction sites using old buildings or walkie-talkies, the burden of replacement and facility construction costs is greatly delayed or abandoned, and thus, it can be obtained in the internet-based communication environment. There was a problem in not enjoying the many advantages that are at all.
The problem to be solved by the present invention is to simply add the IP phone conversion unit to the communication equipment used in existing buildings, etc. to simply convert the voice signal generated from the existing interphone, etc. into a digital signal, to generate or receive the voice signal By assigning a virtual phone number to an interphone, it is possible to connect a call between each interphone, a radio, or an interphone and a conventional IP phone, and to exchange voice information or data, and to use an existing interphone as an IP phone without replacing the interphone. The present invention provides a converter system for using an IP phone of an interphone.
Converter system for using the IP phone of the intercom for achieving the above object, the interphone installed for the purpose of transmitting and receiving voice signals; A voice signal converter for converting an analog voice signal transmitted from the interphone into a digital method; An IP phone converter for allocating a virtual telephone number to the interphone for transmitting the digitally converted voice signal; A VoIP CPU for transmitting the voice signal digitally converted by the voice signal conversion unit by using a virtual telephone number assigned by the IP phone conversion unit as a caller; A communication network transmitting a voice signal transmitted from the VoIP CPU; And a telephone exchange which transmits the voice signal received through the communication network to another interphone to be called.
In this case, the voice signal conversion unit is composed of an A / D converter for converting an analog voice signal to a digital method, one end is connected to the interphone for generating and transmitting the voice signal, the slick (SLIC) provided in the VoIP CPU It is preferable that the other end is connected to the configuration.
The IP phone conversion unit may include a radio interface for forming a communication path between radios through a wireless communication network; An interphone interface for forming a communication path between interphones through a wired communication network; A PSTN interface forming a communication path through a general public telephone network (PSTN); A virtual telephone number assignment unit for assigning a virtual telephone number to a radio and an interphone for transmitting and receiving a voice signal; A control unit controlling an operation of the virtual telephone number assignment unit; And a channel selector for selecting an interface for forming a communication path for transmitting and receiving the voice signal.
In addition, the VoIP CPU is composed of a microcontroller for matching the virtual telephone number to the voice signal of the digitally converted interphone; User space, which is a general application area for use as an IP phone, Kernel Space, which is an area where operating system related programs and a number of device drivers are installed, a plurality of slicks consisting of a line interface circuit in a telephone switchboard, And a DAA which detects the reception sensitivity of the radio signal received in the channel and determines whether communication is possible through each channel.
The present invention is to install the IP phone conversion unit in the existing communication facilities to be used as an IP phone without replacing the terminal such as the existing interphone, the terminal replacement cost and facility construction required to build the IP phone using environment There is an advantage that can significantly reduce the cost.
In addition, the present invention has the advantage that by minimizing the cost required to build the IP phone using environment, more users can experience the advantages of the IP phone cheaply and easily to increase the production efficiency of the work and reduce the communication cost .

Accordingly, the VoIP CPU recognizes the voice signal transmitted from the radio or the interphone as a digital voice signal transmitted from the IP phone having the virtual phone number, so that the VoIP CPU can be used as an IP phone without replacing the radio or the interphone. .
As such, the voice signal matched with the virtual telephone number is transmitted to another radio through a wireless communication network to transmit and receive a voice signal. In the case of an interphone, the voice signal matched with the virtual telephone number is transmitted through the
Accordingly, the present invention converts a voice signal into a digital method and assigns a virtual telephone number to an interphone which generates a voice signal, beyond the conventionally being able to talk only between interphones, thereby transferring the conventional interphone to a telephone exchange (IP / PBX). It can be registered and used like a normal VoIP phone or RoIP phone. The interphone can be connected to an external public telephone network (PSTN), an IP phone, or a general analog phone.
In addition, it is possible to communicate only through a certain frequency within a limited range, and the signal generated from the radio travels on the Internet line as it moves beyond the radio limit, which is difficult to use in areas where buildings that impede the movement of radio waves are concentrated. You can have a conversation. And, if you have multiple radios, you will be able to talk to the radio you want.
