The present invention relates to a mutual communication system between radio users located at a long distance (eg, Seoul ↔ Busan) using an internet network. In particular, a plurality of radios communicate with each other individually or individually regardless of distance. The present invention relates to a radio communication device of a radio using an internet network to connect a communication so as to solve the shortcomings of a conventional radio limited by a distance.

In general, a radio is a device that allows a large number of users to have a group or individual voice communication within the same frequency, such as a radio, a living radio, an industrial radio, a security radio.

However, in the conventional radio as described above, since the voice communication is performed through a frequency assigned to a specific channel, only a short distance communication limited by space is possible.

1 and 2, in the radio 1A and 1B having a plurality of channels,

To configure the transceivers 10 and 10 'connected to the computers 2A and 2B such that the radios 1A and 1B communicate with each other via the Internet network 100 regardless of distance.

The transceivers 10 and 10 'receive and sample analog voice signals transmitted from the radios 1A and 1B, convert the digital voice signals to digital voice signals, or convert the digital voice signals into analog. A codec unit 11 and 11 'for transmitting it to the radio 1A and 1B;

A network processor 13 (13 ') which describes a compressed (or restored) state of a digital (or analog) audio signal converted and output from the codec unit (11) (11') and describes the compressed (or restored) state. A digital signal processor (DSP) (12) 12 'for generating an interrupt signal corresponding to each channel of the radio equipment 1A and 1B so as to inform the user;

Each channel of the radios 1A and 1B is monitored and managed, and the compressed digital voice signal corresponding to the channel is generated according to the interrupt signal of each channel generated from the DSP unit 12, 12 '. 2B and a network processor 13 and 13 'for transmitting and receiving to the radio 1A and 1B via the Internet 100; It is characterized by the configuration.

Here, the codec units 11 and 11 'and the DSP units 12 and 12' constituted in the transceivers 10 and 10 'are configured in the number corresponding to the channels of the radios 1A and 1B. .

In addition, the computer (2A) (2B) has a built-in separate program for receiving the voice signals of the transceivers 10, 10 'and transmitting them through the Internet network 100, the transceiver (10) (10) ') Has a local area network (LAN) port for connecting to the computers 2A and 2B.

Referring to Figures 1 and 2 attached to the operation of an embodiment of the present invention configured as described above are as follows.

First, for convenience of explanation, 1A and 2A are set as the user's radio and a computer, and 1B and 2B are set as the other's radio and a computer.

Subsequently, after connecting the transceiver 10 to the user's computer 2A that can be connected to the Internet network 100 to transmit a voice signal from the user's radio 1A to the other's radio 1B, the user An analog audio signal is generated through the radio 1A.

Then, the analog audio signal generated from the radio 1A of the user is received by the codec unit 11 configured in the transceiver 10.

At this time, the codec unit 11 receives an analog audio signal transmitted from the radio 1A, converts it into a digital audio signal while sampling the analog audio signal, and outputs the digital audio signal to the DSP unit 12.

The DSP unit 12 compresses the digital audio signal converted and outputted from the codec unit 11.

The reason for compressing the digital voice signal through the DSP unit 12 is that when the radio 1A communicates with multiple channels, the data packet is considered in consideration of the bandwidth of the LAN. This is to reduce the size of the voice signal to communicate efficiently and stably.

At this time, the DSP unit 12 compresses the digital audio signal and generates an interrupt signal corresponding to each channel of the radio 1A so as to inform the network processor 13 of the compression state described later.

Then, the network processor 13 transmits the compressed digital voice signal corresponding to the channel of the radio 1A to the other party's radio 1B through the Internet network 100 according to the interrupt signal. To drive the transfer program of

The digital voice signal transmitted and compressed by the radio 1A from the transmission program drive of the computer 2A can be transmitted to the radio 1B of the other party through the Internet network 100.

That is, the other party's computer 2B is also connected to a separate transceiver 10 ',

The network processor 13 'configured in the transceiver 10' outputs the digital voice signal to the DSP unit 12 'when the computer 2B receives the digital voice signal of the user through the Internet network 100. .

Then, the DSP unit 12 'generates an interrupt signal corresponding to each channel of the radio 1B so as to recover the digital voice signal received in the compressed form and inform the network processor 13' of the restored state. Let's go.

At this time, the network processor 13 'controls the digital voice signal of the restoration corresponding to the channel of the radio 1B to the radio 1B of the other party through the codec 11' according to the interrupt signal. Will be performed.

That is, the codec unit 11 'converts the digital voice signal recovered from the control operation of the network processor 13' into an analog voice signal and then transmits the digital voice signal to the radio 1B of the other party. The radio 1B communicates with the user's radio 1A at a distance while allowing the user to hear all the voice information spoken through the radio 1A.

Herein, the operation for transmitting a voice signal from the other party's radio 1B to the user's radio 1A or the operation for receiving the voice information generated from the other user's radio 1A by the plurality of other party's radios are both described above. Since the description is the same as in the description, duplicate description thereof will be omitted.

As described above, the present invention samples the radio communication signal of the user and converts it into a digital signal, and then compresses the converted digital signal and transmits the radio signal to the other party's radio, or restores the radio communication signal that is compressed and transmitted from the other party. By configuring a transmitter / receiver (relay machine) connected to an Internet network (eg, PSDN, ISDN, WAN, etc.) and a computer (PC) connected to it, the radio network can be used for individual or individual groups regardless of distance. It provides an effect that solves the shortcomings of the conventional radio which was limited by the distance while communicating with each other.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
