Description

The present invention relates to the field of wireless voice communication using the transport medium of local and (or) wide area wired and (or) wireless data transmission networks.

From the existing level of technology, from the point of view of the unity of purpose, a radio station is known that performs the function of transmitting speech 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 voice information to other similar devices, as well as receiving voice information. There are many options for radio stations - from the simplest single-channel to complex multi-band designs (Lapovok Ya.S. I am building a KB radio station. 2nd ed., Revised and additional - M .: Patriot, 1992, ISBN 5-7030-0410-1 ). All such devices are based on the principles substantiated in the early developments of N. Tesla (patents US 645576, published on March 20, 1900; US 649621, published on 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 the 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 are: limited communication range, the need to use powerful uneconomical radio frequency amplifiers, the use of rather bulky antennas and their location in a certain way, the strong dependence of the signal quality (up to complete fading) on the terrain, obstacles, interference, distance from the correspondent, and also the impossibility of receiving a signal from the correspondent during the transmission of his signal. 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.

Later developments, some of which are used in practice, theoretically allow to reduce some of the negative effects. In particular, a radio station is known (RU 2225673 C2, publ. 03/10/2004), 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, publ. 05/10/2011), which, however, requires a second channel for transmitting service signals, and hence complicating the circuit. Despite these disadvantages, radio stations are used in the field of communications very widely due to two main features. The first sign is the property of radio broadcasting, due to which the transmitting radio station in real time is simultaneously heard by all similarly tuned devices in the communication range. This confirms the demand for just such functionality in communication devices. The second feature 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 transmission (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, publ. 07.31.2001). Known portable wireless communication device for working in such networks (US 4903325, publ. 20.02.1990) - one of the prototypes of modern mobile phones. A modern device is also known - a dual-mode mobile terminal with double redundancy (RU 2434367 C2, published on November 20, 2011), operating in different modes of digital networks, for example, in GSM and WCDMA.

The disadvantage of the above technical solutions and devices 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). At the same time, the connection establishment time for each session can range from hundreds of milliseconds to several seconds. In addition, in known devices of this type, once a connection is established, voice information is transmitted all the time, and there are no event trackers that could stop and resume the transmission of voice information as needed. Thus, these devices are not suitable for use in the area where radios are usually used (constant and instant communication with other users in the group or with the group manager).

Also known is a wireless voice communication terminal (RU 121411 U1, publ. 20.10.2012), containing a housing, an external or built-in microphone, a loudspeaker, a power supply, an electronic control module based on a microprocessor or microcontroller, a wireless communication device that is connected to the control module with the possibility of exchanging information with it, a module for controlling transmission activation events, which is an electronic circuit based on a microprocessor or microcontroller, made with the possibility of generating control signals for activating and deactivating a transmission based on a change in the state of the control bodies and sensors attached to it, made with the ability to respond to external events, and the electronic circuit is connected to the control module with the ability to transmit these control signals, while the terminal is configured to respond to the event by activating the transmission of digitized speech information, which is selected as a prototype.

However, the known wireless voice communication terminal only provides transmission of pre-digitized voice information, does not provide direct calls and work with subscribers of wireless data transmission systems that implement the PoC (PTT over Cellular) function, and does not provide recording of conversations.

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

The technical result of the claimed device is to provide the possibility of transmitting speech information through it to other similar devices or their groups and / or compatible hardware and software systems and / or wireless communication devices that implement the function immediately after the transmission activation event occurs, using existing wireless and wired networks; expanding the arsenal of technical means for operational voice communication.

The specified technical result is achieved due to the fact that the converged nodal smart repeater contains a housing (1), a power source (2), a wireless communication device (3), a module for monitoring transmission activation and deactivation events (4), an electronic keyboard module (5 ) and an electronic display module (6), characterized in that the device additionally includes a basic electronic module (7) with an operating system, a module for analog-to-digital conversion of speech information (8) and a server (9), while the basic electronic module (7 ) controls the operation of the wireless communication device (3), the module for analog-to-digital conversion of speech information (8), the electronic keyboard module (5), the electronic display module (6) and interacts with the server (9).

In addition, Google Android can be used as the operating system of the basic electronic module (7).

In addition, Microsoft Windows can be used as the operating system of the basic electronic module (7).

In addition, Linux can be used as the operating system of the basic electronic module (7).

In addition, the server (9) of the converged nodal smart repeater has the ability to connect to a wired data network.

In addition, wireless data transmission devices that implement the PoC function (PTT over Cellular) can be connected to the server (9) of the converged nodal smart repeater.

In addition, the basic electronic module (7) and the server (9) of the converged nodal smart repeater implement their functions to activate / deactivate the transmission and transmission of audio messages using a single software package.

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

fig. 3 is a diagram of the interaction of several converged nodal smart repeaters.

FIG. 1 shows a block diagram of a converged nodal smart repeater, including: housing (1), power supply (2), wireless communication device (3), control module for transmission activation and deactivation events (4), electronic keyboard module (5), electronic module display (6), a basic electronic module (7) with an operating system, a module for analog-to-digital conversion of speech information (8) and a server (9). The basic electronic module (7) is connected by an interface bus to a wireless communication device (3). The basic electronic module (7) is connected by the system bus with the module for monitoring transmission activation and deactivation events (4), the electronic keyboard module (5) and with the electronic display module (6). The basic electronic module (7) controls the operation of the wireless communication device (3), the module for analog-to-digital conversion of speech information (8), the electronic keyboard module (5), the electronic display module (6). The basic electronic module (7) interacts with the server (9) via the Ethernet interface.

The body 1 serves as a basis for placing the internal elements of the device, protects them from mechanical damage and ensures ease of use. The terminal's control and indication elements are located on the body: 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 housing and provides power to the basic electronic module 7, the server 9 and the wireless communication device 3 as well, if necessary, additional modules and external devices. The power supply is powered by an external source.

The basic electronic module (BEM) 7 based on a single-board microcomputer ensures the operation of the device: sound processing, polling the state of controls, memorizing settings, responding to changes in the status of controls, changing the status of indicators, checking the conditions for starting and ending transmission, transmitting information to the server 9, receiving and processing information from the server 9. The basic electronic module 7 performs the listed functions through specialized software.

Basic electronic module 7 can be implemented, for example, on the basis of a Smart210 microcomputer, which contains a Samsung S5PV210 microprocessor, 512 MB DDR2 RAM, as well as ports and interfaces for connecting peripheral devices and modules. BEM 7 runs on Android, Linux or Windows operating systems.

The module for analog-to-digital conversion of speech information 8 is designed to convert a speech signal from analog to digital and vice versa. The module for analog-to-digital conversion of speech information 8 can be made in the form of an audio processor that performs the functions of an ADC / DAC and a hardware codec operating in duplex and simplex modes, for example, based on the WM8960 microcircuit. The memory performs the functions of storing device configuration data when the power is off, and is also used during operation as a buffer for storing audio data and the operation of specialized software. For example, an SD card connected to a Samsung S5PV210 microprocessor via its EMMC interface can be used as a storage device.

Electronic display module 6 is designed to display the current state of BEM 7, 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 7 settings. The display electronic module 6 can be implemented on the basis of a TFT LCD touchscreen display and connected to the BEM 7 via the available LVDS interface.

The electronic module of the keyboard 5 is intended for operational control of the electronic module of the display 6 and includes two buttons with the "back" function to return to the previous menu item, a button with the "menu" function to quickly open the specialized software menu section. The electronic module of the keyboard 5 can be implemented on the basis of membrane buttons and connected to the BEM 7 through the existing keyboard interface.

Server 9 is designed to receive audio and other information from BEM 7, distribute it between PoC system subscribers and transmit information addressed to the radio communication network to BEM 7. In addition, server 9 may be able to record all received audio messages, as well as promptly combine audio messages from PoC subscribers, compatible hardware and software systems, and several instances of the utility model into groups, assigning priorities for messages and groups, managing subscriber statuses. Server 9 can be implemented on the basis of an integrated Mini ITX motherboard, which contains an Intel Core i7 microprocessor or equivalent, 8 GB or more RAM, 512 GB or more SSD disk, as well as ports and interfaces for connecting peripheral devices and modules. Server 9 runs on Microsoft Windows and / or Linux operating systems and uses a DBMS. Server 9 implements its functions using specialized software. Server 9 is connected to BEM 7 using the available 100BASE-T interface. To connect subscribers of the PoC system and other instances of the utility model to the server, a data transmission network can be used, the connection to which is carried out by the server 9 using the available 100BASE-T interface.

The set of control commands, transmission of audio messages, service information about the status of devices, control and other data forms its own internal protocol for interaction between PoC subscribers, utility model devices and the server. In this case, the direct data transmission to the communication network and the receipt of data from the communication network is carried out by means of standard network protocols TCP and / or UDP.

Wireless communication device 3 is intended for the exchange of voice information with other wireless communication devices and can be based on a radio station operating in PTT (Push to talk) mode, which, depending on the purpose of the device, can operate in a radio communication network of standards: TETRA, DMR, P25, MRT1327 and analog networks. For example, a radio station "RADON-151 P45" (ASTF.464512.012 TU) can be used as a wireless communication device, connected to the module for monitoring transmission activation and deactivation events 4 through the corresponding connector.

The use of ready-made unified wireless communication devices 3 allows, by replacing them, to ensure the compatibility of the utility model with existing radio communication networks of various standards, as well as to ensure maintainability and simplify the adjustment of products.

FIG. 2 shows a block diagram of the operation of the utility model. It is assumed that the server 9 is pre-switched on and has a stable connection to the data network. BEM 7 and Wireless Device 3 are also on and ready to go. At the preliminary stage, server 9 launches specialized software that contains the necessary parameters for interacting with BEM 7, compatible hardware and software systems and other PoC subscribers: user credentials, their aliases, signs of participation in groups and other information necessary for the operation of server 9. At the preliminary stage, BEM 7, using special software, reads the initial parameters for operation from memory: server 9 network address, connection credentials, audio signal level and other service information necessary for operation. After successful start-up, BEM 7 establishes a network connection to server 9 and goes into standby mode. The wireless communication device 3 at the preliminary stage is switched on to the desired radio channel and goes into the standby mode ("reception on duty"). The preliminary stage includes identification, determination of the status and priority of devices compatible with the smart repeater, available or not available for transmitting / receiving audio messages.

The electronic circuit of the module for monitoring transmission activation and deactivation events 4 interacts with the wireless communication device 3 and, upon receiving an audio message on the received radio channel, performs audio capture and informs BEM 7 about the start of the audio message transmission. The analog-to-digital conversion of the audio message is carried out by the analog-to-digital conversion module of speech information 8 using the WM8960 audio processor. Encoding, compression and additional processing of the audio message is carried out programmatically in BEM 7 using the computing resources of the Samsung S5PV210 microprocessor. The well-known open source real-time audio codecs - OPUS - are used for encoding. The generated audio messages are sent by BEM 7 to the server 9, where they are stored and redirected for receiving to addressees over the data network.

The server 9 is constantly receiving data from the network. Audio messages intended for transmission to wireless subscribers are sent by the server 9 to the BEM 7, which receives them, restores and decodes them. Upon receipt of an audio message, BEM 7 using the activation / deactivation module 4 activates the transmission of the wireless communication device 3 and sends the recovered decoded message to the digital-to-analog conversion module 8, which sends the converted analog signal to the line input of the wireless communication device 3. Wireless communication device 3, having received the activation signal from the activation / deactivation module 4, switches to the transmission mode on the preselected radio channel and transmits the audio message received from the digital-to-analog conversion module.

The set of control commands, transmission of audio messages, service information about the status of devices, control and other data forms its own internal protocol for interaction between PoC subscribers, utility model devices and the server. In this case, the direct data transmission to the communication network and the receipt of data from the communication network are carried out using standard network protocols TCP and / or UDP. Other protocols available on a particular data network may also be used.

FIG. 3 shows a diagram of the interaction of several converged nodal smart repeaters. The diagram shows that several instances of the utility model can interact with each other and with geographically dispersed radio communication 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 that implement the PoC function using a data transmission network, which is a transport medium for information transmission. Subscribers can work in different groups with different priorities. Servers included in various converged nodal smart relays can back up each other.

The communication range in such a converged system, compared to using only conventional radio stations or only mobile radiotelephone networks, 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 simply integrate into its composition already functioning radio communication networks, different in terms of 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, as well as wireless data transmission devices that implement the PoC function, which interact with converged nodal smart repeaters by means of constantly improving modern wired and wireless data transmission networks.

Thus, the users of the proposed utility model:

1) Get rid of the need to replace existing radio communications with new devices when upgrading the network;

2) Expand the coverage area due to modern wired / wireless data transmission networks;

3) Increase the number of subscribers due to compatible hardware and software systems, as well as wireless data transmission devices that implement the PoC function;

4) Get the ability to flexibly configure the groups of users of the system using various means of communication, as well as the ability to record all radio conversations.

The industrial applicability of the utility model is confirmed by technical implementation in the OMEGA K500 concentrator in various versions [OMEGA K500 concentrator ASTF.468354.004, ASTRAKOM LLC].
