Description

This utility model relates to the field of wireless voice communication using the transport medium of local and (or) global wireless data networks.

From the existing level of technology, from the point of view of unity of purpose, a radio station is known that performs the function of transmitting voice information to similar devices using radio waves, which, in the general case, includes: a low-frequency path, a modulator, a demodulator, a high-frequency transmitting path (transmitter), a high-frequency receiving path (receiver), and transmits speech information to other similar devices, as well as receives speech information. There are many options for radio stations - from the simplest single-channel to complex multi-band designs (Lapovok Y.S. I am building a KB radio station. 2nd ed., Revised and added. - M .: Patriot, 1992, ISBN 5-7030-0410-1 ). All such devices are based on the principles justified in the early developments of N. Tesla (patents US 645576, published March 20, 1900; US 649621, published May 15, 1900).

The most widespread in civil mobile communication systems are simplex radio stations operating at a certain frequency in the VHF range of radio waves propagating within line of sight and communicating with each other or with a base radio station directly, or, less often, through a repeater.

The disadvantages of this technical solution is: the ability to work only with radio stations operating in a similar standard, which limits the communication range and leads to the need to use powerful uneconomical radio frequency amplifiers with rather bulky antennas and arrange them in a certain way. In addition, such communication systems are characterized by irrational use of the frequency resource, since one radio station completely occupies (blocks) the frequency channel during transmission.

More recent developments, some of which are applied in practice, theoretically reduce some of the negative effects. In particular, a radio station is known (RU 2225673 C2, published on March 10, 2004), which uses a solution that provides duplex mode when operating at one frequency. Also known is a method and a system for interrupting a transmitting subscriber in a wireless communication system (RU 2418392 C2, published on May 10, 2011), which, however, requires the presence of a second channel for transmitting service signals, and therefore complicating the circuit. Despite these shortcomings, radio stations are used in the field of communications very widely due to two main features. The first feature is the property of broadcasting, due to which the transmitting radio station is simultaneously heard in real time by all similarly configured devices in the communication coverage area. This confirms the demand for just such functionality in communication devices. The second sign is ease of use and a minimum of controls used in the communication process.

The most effective technical problems of radio communication, caused by the phenomenon of attenuation of radio waves, are solved when building wireless cellular networks, in which the use of frequency channels is optimized and the transfer (handover) of subscriber devices from one fixed base station to another is carried out without interrupting communication (US 4670899, publ. 2.06. 1987; US 6269087, published 07/31/2001). The disadvantage of the above technical solutions designed to work in cellular networks is that voice communication in them is carried out between two (less often - several) subscribers in a session mode (connection - conversation - disconnection). In this case, the connection establishment time for each session can vary from hundreds of milliseconds to several seconds. These devices are not suitable for use in an area where radios are normally used (permanent and instant communication with other users in the group or with the group manager). In addition, the above technical solutions provide only the transmission of radio signals in a specific standard. Simultaneous transmission of radio signals between subscribers of radio networks of different standards is not possible.

A convergent nodal smart repeater is also known (RU 205724 U1, published on 07/30/2021), containing a housing, a power source, a wireless communication device, a module for monitoring transmission activation and deactivation events, an electronic keyboard module, an electronic display module, a basic electronic module with an operating system, a module for analog-to-digital conversion of speech information and a server, which was chosen as a prototype.

However, the well-known convergent nodal smart repeater provides the transmission of radio signals from subscribers of only one standard of radio communication systems. Simultaneous transmission of voice information between subscribers of radio networks of different standards of radio communication systems is not possible.

The task to be solved by the claimed utility model is to eliminate the above disadvantages of devices known from the prior art.

The technical result of the claimed device is to provide the possibility of simultaneous transmission of speech information through it to other similar devices or their groups, to other devices operating in standard 1 and in standard 2 or their groups, and / or compatible hardware and software systems and / or wireless communication devices.

The specified technical result is achieved due to the fact that the multiprotocol repeater contains a housing (1), a power source (2), a basic electronic module (3) with an operating system, an electronic keyboard module (4) and an electronic display module (5), consisting of The device additionally includes a radio signal switching module (6), a radio signal processing module of standard 1 (7), a radio signal processing module of standard 2 (8), a radio signal transceiver of standard 1 (9), a radio signal transceiver of standard 2 (10), an antenna of a radio signal transceiver of standard 1 ( 11), the radio signal transceiver antenna of standard 2 (12), while the basic electronic module (3) controls the operation of the radio signal switching module (6), the electronic keyboard module (4), the electronic display module (5), the radio signal switching module (6) through a standard 1 radio signal processing module (7) and a standard 2 radio signal processing module (8) controls the operation of the respective transceivers standard 1 radio receiver (9) and standard 2 radio transceiver (10).

In addition, the radio transceiver antenna of standard 1 (11) and the radio transceiver antenna of standard 2 (12) can be made in the form of a dipole or vertical antenna or an antenna combiner system.

In addition, the basic electronic module (3), the standard 1 radio signal processing module (7) and the standard 2 radio signal processing module (8) implement their radio signal switching functions using a single software package.

The features and essence of the utility model are illustrated by drawings:

In FIG. Figure 1 shows a block diagram of a multiprotocol repeater, including: a housing (1), a power supply (2), a basic electronic module (3) with an operating system, an electronic keyboard module (4), an electronic display module (5), a radio signal switching module (6) , radio signal processing module standard 1 (7), radio signal processing module standard 2 (8), radio signal transceiver standard 1 (9), radio signal transceiver standard 2 (10), radio signal transceiver standard 1 (11), radio transceiver antenna standard 2 ( 12).

Case 1 serves as a basis for placing the internal elements of the device, protects them from mechanical damage and provides ease of use. On the body there are controls and indications of the terminal: an on-off button, a display, connectors for connecting external devices, grounding, power supply and antennas.

The power supply 2 is located in the terminal case and provides power supply to the basic electronic module 3, the radio signal transceiver of the 1 9 standard and the radio signal transceiver of the 2 10 standard, as well as, if necessary, additional modules and external devices. The power supply receives power from an external source.

The basic electronic module 3 performs the above functions through specialized software.

The radio signal switching module 6 is intended for switching voice signals, information and status messages between the standard radio signal processing module (MORS) 1 7, the radio signal processing module of the standard 2 8 and the basic electronic module 3. The radio signal switching module 6 can be made based on the Xilinx Spartan XC350 FPGA and connected to BEM 3, MORS 1 7 and MORS 2 8.

The electronic display module 5 is designed to display the current state of the BEM 3, its current status and settings of specialized software. The touchscreen function allows you to quickly switch between sections of the software menu and adjust the BEM 3 settings. The electronic display module 5 can be implemented on the basis of an LCD TFT touchscreen display and connected to the BEM 3 via the available LVDS interface.

The electronic keyboard module 4 is designed for operational control of the BEM 3 and includes two buttons with the “back” function to return to the previous menu item, a button with the “menu” function for quickly opening the menu section of specialized software. The electronic module of the keyboard 4 can be implemented on the basis of membrane buttons and connected to the BEM 3 through the existing keyboard interface.

MORS 1 7 is designed to process digital radio signals of standard 1 and analog radio signals with frequency modulation received from the transceiver of radio signals of standard 1 9. As a module for processing radio signals of standard 1 (7), an integrated circuit CMX7341 FI-2.X can be used.

MORS 2 8 is designed to process digital radio signals of standard 2 and analog radio signals with frequency modulation received from the transceiver of radio signals of standard 2 10. As a module for processing radio signals of standard 2 8, an integrated circuit CMX7341 FI-4.X can be used.

The radio signal transceiver of standard 1 9 is designed to receive and transmit digital radio signals of standard 1 and analog radio signals with frequency modulation received from the antenna of the transceiver of radio signals of standard 1. As a transceiver of radio signals of standard 1 9, an assembly with an integrated circuit of the CMX992 transmitter, an integrated circuit of the CMX994 receiver and an amplifier can be used power CMH902.

The radio signal transceiver of standard 2 10 is designed to receive and transmit digital radio signals of standard 2 and analog radio signals with frequency modulation received from the antenna of the transceiver of radio signals of standard 2. As a transceiver of radio signals of standard 2 10, an assembly with an integrated circuit of the CMX992 transmitter, an integrated circuit of the CMX994 receiver and an amplifier can be used power CMH902.

The 1 11 standard radio transceiver antenna is designed to convert electrical signals from the 1 9 standard radio transceiver into radio signals of various ranges and vice versa. As radio transceiver antennas of the 1 11 standard, for example, dipole antennas of the D1 or D2 type for various bands and vertical antennas of the A5 type for various bands can be used.

The 2 12 standard radio transceiver antenna is designed to convert electrical signals from the 2 10 standard radio transceiver into radio signals of various ranges and vice versa. As radio transceiver antennas of the 2 12 standard, for example, dipole antennas of the D1 or D2 type for various bands and vertical antennas of the A5 type for various bands can be used.

The use of a radio transceiver of standard 1 9 and a radio transceiver of standard 2 10 makes it possible to ensure the compatibility of the utility model with existing radio networks 1 and 2.

The principle of operation of the utility model is as follows. It is assumed that BEM 3, Radio signal switching module 6, MORS 1 7, MORS 2 8, radio signal transceiver of standard 1 9, radio signal transceiver of standard 2 10, are switched on and ready for operation. At the preliminary stage, BEM 3 launches specialized software that contains the necessary operating parameters. At the preliminary stage, the BEM 3 and the radio switching module 6, using special software, read from the memory the initial parameters for operation: the sound signal level, the switching scenario and other service information necessary for operation. After the successful activation of the BEM 3 is connected to the module switching radio signals 6 and goes into standby mode. MORS 1 7, MORS 2 8, transceiver of radio signals of standard 1 9, transceiver of radio signals of standard 2 10 at the preliminary stage are switched on to the desired radio channel and goes into standby mode (“standby reception”). The preliminary stage includes the identification, determination of the status and priority of devices compatible with the multiprotocol repeater, available or unavailable for sending/receiving voice messages.

BEM 3 interacts with the radio signal switching module 6. The radio signal switching module 6, upon receiving an audio message from MORS 1 7 or MORS 2 8 on the received radio channel, performs audio capture. In accordance with the selected switching scenario, the radio signal switching module 6 informs the BEM 3 about the start of the transmission of a voice message. Analog-to-digital conversion of a voice message, encoding, compression and additional processing of a voice message is carried out programmatically in BEM 3 using the computing resources of the Samsung S5PV210 microprocessor. The well-known open-source real-time audio codecs - OPUS - are used for encoding.

Voice messages intended for transmission to network subscribers of standard 1 and standard 2 are sent to BEM 3, which receives, restores and decodes them. Upon receipt of a voice message, the BEM 3 transmits it to the radio signal switching module 6, which, in accordance with the selected scenario, activates the operation of MORS 1 7 and/or MORS 2 8 and the radio signal transceiver of the standard 1 9 and the radio signal transceiver of the standard 2 10, respectively.

In FIG. 2 shows a diagram of the interaction of several multiprotocol relays. The diagram shows that several instances of the utility model can interact with each other and with geographically dispersed radio networks of various standards and ranges. Instances of the utility model interact with each other, as well as with compatible hardware and software systems and wireless data transmission devices. Subscribers can work in different groups with different priorities.

The communication range in such a convergent system, compared to using only conventional radio stations, is greater, since the system allows you to combine system elements depending on the coverage area in a particular area. In addition, the system allows you to easily integrate into its composition already functioning radio networks of various standard, range, coverage area and service area. At the same time, the system has the ability to scale, taking into account the use of compatible hardware and software systems that interact with multiprotocol repeaters.

Thus, users of the proposed utility model:

1) Get a multi-protocol repeater of radio signals of various radio standards;

2) Increase the number of subscribers by relaying radio signals between subscribers operating in radio networks of various standards and compatible hardware and software systems.

3) They get the possibility of flexible configuration of switched user groups of various standards and radio communication ranges.

The industrial applicability of the utility model is confirmed by the technical implementation in the OMEGA R180U multiprotocol repeater in various versions [OMEGA R180U multiprotocol repeater ASTF.468354.005, ASTRAKOM LLC].
