Description

Field of technology: utility model

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

State of the art

From the current 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), and a high-frequency receiving the 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 (Y. S. Lapovok. 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 justified in the early development of N. Tesla (patents US 645576, publ. March 20, 1900; US 649621, publ. May 15, 1900).

Simplex radio stations operating at a specific frequency in the VHF range of radio waves propagating within line of sight and communicating directly with each other or with the base radio station most often, or, less commonly, through a repeater, are most widely used in civilian mobile communication systems.

The disadvantages of this technical solution are: the limited communication range, the need to use powerful uneconomical RF 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 inability to receive the signal of the correspondent during the transmission of its signal. In addition, such communication systems are characterized by irrational use of the frequency resource, since one radio station during transmission completely occupies (blocks) the frequency channel.

Later developments, some of which are put into practice, theoretically allow some negative effects to be reduced. In particular, the known radio station (RU 2225673 C2, publ. 10.03.2004), which uses a solution that provides duplex mode when operating at the same 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 requires, however, the presence of a second channel for transmitting service signals, and therefore, complicating the circuit.

Despite these shortcomings, radio stations are widely used in communications due to two main features. The first sign is the property of broadcasting, due to which the transmitting radio station in real time simultaneously hear 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, which optimize the use of frequency channels and transfer (handover) subscriber devices from one stationary base station to another without interrupting communication (US 4670899, publ. 2.06. 1987; US 6269087, published July 31, 2001). Known portable wireless communication device for working in such networks (US 4903325, publ. 02.20.1990) - 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, 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 session mode (connection - conversation - disconnection). At the same time, the connection establishment time for each session can vary from hundreds of milliseconds to several seconds. In addition, in known devices of this type, after establishing a connection, voice information is transmitted all the time, and there is no means of event tracking that could stop and resume the transmission of voice information as necessary. Thus, these devices are unsuitable for use in the area where radio stations are usually used (constant and instant communication with other users in the group or with the group dispatcher).

Combined solutions are also known that can be used both as a radio station with a limited range and as a cellular communication terminal (WO / 2006/097783, publ. 09/21/2006; RU 2280961 C2 publ. 07/27/2006; RU 2351074 C2, publ. 27.03. 2009). However, in fact, these solutions are two heterogeneous devices combined in a single housing. Accordingly, these disadvantages are also characteristic of them.

The technical result of the claimed device is the ability to transmit voice information through it to other similar devices or their groups and / or compatible hardware and software systems immediately after the transmission activation event, using existing wireless networks; expanding the arsenal of technical tools for operational voice communications.

In addition, the terminal may be configured to respond to the event by activating the transmission of digitized voice information, where the event is a specific user control command and / or control signal from another device.

In addition, the terminal can be configured to respond to the event by activating the transmission of digitized voice information, where the event is the appearance in the coverage area of its microphone of sound with certain characteristics and / or a change in the orientation of the terminal in space. In addition, the terminal further comprises an interface for connecting it to other audio devices or to radio stations (transceivers) for relaying the signal.

Utility Model Implementation

Next will be described in detail embodiments of the utility model in combination with the accompanying drawings.

Figure 1 shows the structural diagram of the modules of the utility model, in the most general form including: housing 1, a remote or built-in microphone 2, loudspeaker 3, power supply 4, control module - an electronic circuit based on microprocessor 5, wireless device 6, control module transmission activation events 7.

The housing 1 serves as the basis for the placement of the internal elements of the device, protects them from mechanical damage and provides ease of use. The terminal controls are located on the body, at a minimum: an on / off button, volume control, status indicators, connectors for connecting external devices. Also on the case may be a transmission activation button.

Remote or built-in microphone 2 converts acoustic waves of sound frequency into electrical vibrations for their subsequent processing. Structurally, the microphone is located in the device housing or outside the housing and is connected to the electronic circuit of the control module 5 directly, by cable, or via wireless technology. In case the microphone is made remote, the transmission activation button for convenience is placed on its body. As a microphone, for example, a MEMS model MP45DT01 microphone having a single-bit PDM output can be used.

Loudspeaker 3 is used to reproduce audio information addressed to the user. Structurally, it can be located in the device case or outside the case and can be connected to the electronic circuit of the control module 5 directly or through wireless technologies.

The power supply 4 is located in the terminal housing and provides power to the electronic circuit of the control module 5, the access module to the data transmission network 6, and also, if necessary, additional modules and external devices. The power source may be a battery (battery) or an electronic circuit receiving power from an external source.

The electronic circuit of the control module based on microprocessor 5 ensures the operation of the device: sound processing, interrogation of the state of the controls, storing settings, responding to a change in the status of the controls, changing the status of the indicators, checking the conditions for activation of the transmission, transmitting information through the wireless device 6 to the data network , receiving and processing information from the network. The control module can be implemented, for example, based on the BCM2835 chip, which contains a microcontroller, PCM / I2S audio interface, as well as ports and interfaces for connecting peripheral devices and modules. The control module performs the above functions due to the recorded set of commands, the general principle of which is reflected in the algorithm diagram (see Figure 2) and is described in detail below. In addition, the control module may include a digital-to-analog converter (DAC) and a low-frequency amplifier (VLF), implemented, for example, on the basis of the combined CS43L22 chip, the input of which is connected to the BCM2835 microprocessor via the I2S interface, and the output is connected directly to the loudspeaker. In addition, the control module may include an audio processor that performs the functions of an ADC / DAC and a hardware codec in duplex mode, for example, based on a low-energy chip VS1063, which has microphone and line inputs and is connected to the BCM2835 microprocessor via I2S and / or UART interface. In addition, a storage device (memory) may be included in the control module. The memory performs the functions of storing device configuration data when the power is off, and is also used in the process as a buffer for storing audio data. As a storage device, for example, an SD card can be used connected to the BCM2835 microprocessor via the EMMS interface available in it.

Wireless device 6 communicates with other instances of devices via data networks and can, depending on the purpose of the device, work in any of the digital networks of standards: IEEE 802.11 (Wi-Fi), 802.16 (WiMax), GSM / GPRS (2G), IMT-2000 (3G), LTE (4G) and others, providing the necessary data transfer rate of 64 kbit / s and more. For example, the following components can be used as a wireless communication device: SQN1280 micro-assembly (IEEE 802.16) connected to the BCM2835 microprocessor via the SPI interface; micro-assembly SIM5320E (2G / 3G) connected to the BCM2835 microprocessor via USB; micro assembly SQN3140 (LTE), connected to the BCM2835 microprocessor through the SPI interface. In addition, electronic components are designed for several standards that can support multiple networks simultaneously or in turn, for example, the BCM2091 chip operating in the 850/900/1800/1900/2100 MHz bands. Isolation of module 6 from the main electronic circuit allows the use of ready-made unified devices, in a simpler way (by replacing the module), to ensure that the utility model complies with national telecommunication standards and local conditions, as well as maintain maintainability and simplify product setup. At the same time, structurally, the wireless communication device 6 can be located either on the same printed circuit board as the main electronic circuit, or separately.

The transmission activation event control module 7 is an electronic circuit that is connected to the control module 5 with the possibility of exchanging information with it via the UART interface. Structurally, the transmission activation event control module 7 can be located either on the same printed circuit board as the main electronic circuit or separately. The function of the event monitoring module is to monitor the status of event sensors and devices connected to this module and transmit information about their state to the control module 5 as a signal for activating the transmission of digitized voice information after the occurrence of the transmission activation event. Transmission activation events can be, for example: a user's control command, a control signal from another device on the network, the appearance of sound with certain characteristics in the microphone’s coverage area, a change in the orientation of the terminal in space, a change in the state of the electronic device connected to the terminal via the interface. An additional function of the event monitoring module may be, for example, monitoring the status of an electronic device connected to the terminal via an interface, transmitting information about its status to the control module 5, as well as switching analog audio input and output circuits. The transmission activation event control module can be implemented, for example, on the basis of the STM32F100C series microcircuit, which contains USART, I2C, SPI, CEC interfaces for connecting peripheral devices and modules, GPIO ports, as well as multi-channel digital-to-analog D / A converter (DAC) and analog Digital to analog converter (ADC). A minimum set of controls (microswitches connected to individual terminals of the GPIO port of the STM32F100C chip) and indicators (LEDs connected to individual terminals of the GPIO port of the STM32F100C chip) can also be included in the event control module. Another embodiment of the utility model may provide for the possibility of switching analog audio input and output audio circuits between the terminal itself and an external audio device connected to it via an interface - in this case, discrete switching elements, for example, relays and transistors, controlled by the event control module can be included via the GPIO port of the STM32F100C chip. This can be applied in the case of implementing a utility model, where the terminal includes a radio module. If the embodiment of the utility model does not require the need to connect a large number of sensors and indicators, it is possible, for example, to execute a transmission activation event monitoring module using free ports of the control module and / or using a microcontroller with fewer ports and interfaces. In this case, the transmission activation event control module performs the above functions by flashing a given set of commands, the general principle of which is reflected in the algorithm diagram (see Figure 3) and is described in detail below.

To provide additional functionality, the utility model can be supplemented with the following components:

1) an accelerometer or a position sensor - if the event of transmission activation is a change in the orientation of the terminal in space;

2) an interface (s) in the form of ports and connectors - for interaction with other electronic devices or external audio devices;

3) an additional single-mode or multi-modem modem (or network adapter) - to ensure operation of an additional standard in the network, or to ensure operation in more than one network (group);

4) display - for receiving and demonstrating to the user text and (or) graphic and (or) video data, for entering and transmitting text and (or) graphic data;

5) keyboard - for entering and transmitting text and (or) graphic data;

6) video camera - for transferring photos and (or) video data;

7) a radio module (pre-transmitter) for direct communication of similar devices without the use of SPD or when SPD is not available. At the same time, manual (including remote) or automatic selection of one of the terminal operating modes is provided — using only SPD, using only a radio module, or a combined one;

8) a system for determining their location.

The position sensor can be implemented, for example, based on the MMA7455L chip connected to the STM32F100C chip via the SPI interface. The interface for interaction with other electronic devices or audio devices can be implemented, for example, in the form of a multi-pin connector (s), the individual terminals of which (which) are connected to the individual terminals of the GPIO port of the STM32F100C chip. As an additional single-mode or multi-mode modem (or network adapter), for example, any commercially available device for this purpose connected to the BCM2835 microprocessor via the existing USB interface can be used. As a display, for example, one of the MT 12232, WG12232E-TML type modules connected to the BCM2835 microprocessor via the GPIO port pins, or PCD8544 module connected to the STM32F100C chip via the SPI interface can be used. The terminal keyboard can be implemented, for example, in the form of a set of microswitch buttons connected to individual terminals of the GPIO port of the STM32F100C chip or, in another embodiment, to individual terminals of the GPIO port of the BCM2835 microprocessor. The system for determining its location can be implemented, for example, on the basis of the STA8088F module, connected to the BCM2835 microprocessor via the I2C interface and providing reception of signals from the GLONASS, GPS, Galileo, QZSS systems.

The best embodiment of the utility model may include all of the above additional components to realize maximum functionality.

Figure 2 shows a block diagram of a utility model. It is assumed that the terminal 8 is pre-connected, has a connection to the SPD 9. At the preliminary stage, in the embodiment of the utility model described above, the microprocessor BCM2835 of the control module reads the parameter table from the SD memory through its EMC interface. The parameter table contains at least one network address of another instance of the terminal with which it is supposed to exchange audio data (hereinafter referred to as such terminals are referred to as compatible) and / or a subnet address for transmitting information to an indefinite circle of devices connected to it. Also, the sound volume settings, a list of events during which voice information will be transmitted, frame size, other service information necessary for the operation of the device can be stored in the parameter table. In another embodiment of the utility model, the parameter table may contain the address of the server on which the parameter table is stored. In this case, the parameters are read from the server and, thus, can be changed centrally by the administrator. The preliminary stage may also include identification of the status of devices (correspondents) compatible with the terminal, accessible or inaccessible for interaction.

The electronic circuit of the terminal control module carries out continuous audio capture 10 of the sound in the microphone coverage area and converts fragments of the analog audio signal of the set duration to digital form - frames 11. The analog-to-digital conversion is carried out directly in the microphone having a single-bit PDM output. In another embodiment of the utility model, in the case of using an analog microphone, analog-to-digital conversion can be performed, for example, in a transmission activation event control module, whose STM32F100C chip contains a multi-channel digital-to-analog converter (DAC) and an analog-to-digital converter (ADC) either in the audio processor. The digital audio stream is fed to the input of the PCM subsystem of the microprocessor BCM2835 of the control module and is accumulated in the buffer. After the accumulation of the amount of data corresponding to the set frame size (for example, 20 ms or 160 samples), the frame, using the DMA subsystem, is copied to the microprocessor RAM, and the buffer is freed. Then, the condition for activating transmission 12 is checked. Such a condition may be the action of the user (for example, pressing a button), a command from a remote terminal, and the status of the position sensor. As described above, the state of sensors and interfaces is monitored by the transmission activation event monitoring module (see FIG. 3), which transmits information about their status to the control module. The firmware of the control module compares information about the state of the sensors with a list of events in which the transmission of voice information should occur. In case of coincidence detection, the audio data frame is transmitted via the wireless communication device 14 and the data network to compatible terminals whose address (s) are contained in the parameter table of the control module.

Also, a transmission activation event may be the appearance in the microphone area of sound with certain characteristics (amplitude, frequency or spectrum), therefore, audio capture occurs constantly. In this case, the firmware of the control module analyzes the frame received in the RAM of the microprocessor. This can be done, for example, by calculating the average value of the samples that make up the frame. If the average value of samples significantly exceeds the background level, this means that sound with sufficient amplitude to transmit the sound appears in the microphone coverage area. If the transmission activation condition is fulfilled, the frames are encoded into buffer 13. Modern SPDs do not impose significant restrictions on the amount of information transmitted. In the shown embodiment of the utility model, compression or additional processing of frames by the codec is not performed, audio data is transmitted without loss of quality. Under coding 13 is meant the formation of a data packet consisting of a marker command and the raw frame itself. The packet thus formed is transmitted directly to the network 14. Due to this, the microprocessor algorithm is simplified and its power consumption is reduced, which positively affects the battery life of the terminal.

In another embodiment, in order to consume less data during transmission and transfer them faster for destination devices 14 in the network, the encoding step 13 includes preliminary processing of the frames by the codec. The use of the ITU-T G.722 codec standardized by the International Telecommunication Union is envisaged. This codec uses a sampling frequency of 16 kHz, which is consistent with the capabilities of the microprocessor BCM2835 control module. Other well-known codecs can be used to encode the speech signal, for example, the Speex open source codec, which uses a variable sampling rate and a frame size of 30 ms.

In another embodiment of the utility model, it is possible to use a hardware codec - an audio processor based on the VS1063 chip, which is part of the control module and connected to the BCM2835 microprocessor via the I2S interface. In this case, the analog audio signal from the microphone or the linear input of the terminal goes to the MICP input of the audio processor, passes through an integrated mixer, is converted to digital form by the built-in ADC, encoded in the VSPSP4 core. Coded samples are sent to the main processor BCM2835, where the data packet for transmission is finally formed.

The reception of data from the network 15 also occurs constantly, in standby mode. The received audio data after integrity checking is subjected to decoding 16. In the shown embodiment of the utility model, decoding means parsing a packet received from the network and extracting from it an audio data frame suitable for inverse (digital-to-analog) conversion. In other embodiments described above for the encoding process, after parsing, the frame is decoded by the appropriate codec (ITU-T G.722 or Speex). The decoding process is the opposite of the encoding process and is performed by the same means. The formed frames are recorded in the buffer 17, then converted from digital to analog form 18 and reproduced 19. The use of the buffer 17 allows you to apply playback delay and repeat playback if the device user did not hear the received information or was absent. Since the processes of receiving data from the network and transmitting voice information to the network are not interconnected, duplex operation is easily implemented.

In addition to audio data, the terminal transmits to the network and receives from the network service information about the status of the devices, control commands 20, settings, control and other data necessary for operation. To ensure the standby mode "always in touch", the terminal monitors the quality of the connection at least once a minute and restores communication with the SPD during breaks. If it is immediately impossible to send data, they are stored in the send buffer and can be sent when communication is restored.

The set of control commands, audio data transmission packets, service information about the status of devices, control and other data forms its own internal protocol for the interaction of terminals and voice information, however, direct data transmission to the network and receiving data from the network is carried out using standard network protocols TCP and / or UDP . Other network protocols available in a particular SAP can be applied.

Figure 3 shows a block diagram of the operation of the transmission activation event monitoring module. The module performs its functions by flashing a given set of commands in the STM32F100C chip. In the general case, the chip operation algorithm is as follows. First of all, it polls the status of 21 USART, I2C, SPI, СЕС interfaces, GPIO port pins, to which event sensors and terminal controls are connected. The current status of the ports and interfaces of the event sensors is compared with the status word 22 previously recorded in the module memory. In case changes have occurred, a new status word is written into the module 23 memory, the changed status word is transmitted to the control module 24 as a signal to activate the transmission of digitized voice information. Then the module checks for the presence of commands 25 from the control module, which are transmitted via the UART interface. In accordance with these commands, the state of the indicators 26 is established by setting the corresponding logical signal levels at the terminals of the GPIO port. In other embodiments, when, for example, a display module is connected to the STM32F100C chip via an SPI, the transmission activation event control module updates the display status by writing data to this interface. In addition, in accordance with the commands of the control module, the state of the output lines of the interface of external devices can be changed. Then, the status of the input lines of the external device interface 27 is checked. The current status of the ports and interfaces of external devices is compared with the status word 28 previously recorded in the module memory. In case of changes, a new status word is written to the module 29 memory, the changed status word is transferred to the module control 30. In the embodiment of the utility model, where the analog audio circuits of the input and output are switched, the module also changes the state of the 31 pins of the GPIO port of the STM32F100C chip to the cat The discrete switching elements are connected to each other. This can also be applied in the case of implementing a utility model where the terminal includes a radio module or where an audio device operating in the signal relay mode is connected to the terminal. The described sequence of actions is repeated in a cycle.

Figure 4 shows the simplest version of the interaction scheme of two instances of a utility model. The diagram shows how the terminals 32 and the data network 33 form a system in which the terminals interact using the DDS as a transport medium for transmitting information.

Figure 5 shows a more complex version of the interaction scheme of several instances of the utility model. The diagram shows how terminals 32 and terminal 34, which has more than one module for network operation, interact in groups, using various SPDs 35, 36, 37, including those connected by gateways 38, as a medium for transmitting information. Interact with terminals there may also be hardware and software complexes 39 compatible with terminals in terms of a data exchange protocol, for example, installed in dispatch services. In particular, with the help of such complexes it is most optimal to configure the terminals and configure them. The diagram shows how users can configure terminals in various ways to work in the necessary networks and groups. At the same time, the terminals transmit voice and service information to each other directly using the network addresses of the terminals, or transmit this information through server 40. Server 40 can be used as an auxiliary address server (for example, if the terminals have dynamic addresses), or as a full-fledged relay data packets.

The range and quality of communication in such a system, in comparison with the use of conventional radio stations, is less dependent on the individual characteristics of each device and its location, if the device is in the coverage area of any SPD. Since modern public-access LDSs are created and constantly modernized in order to cover the maximum number of users in the territory, their service areas are obviously wider than the coverage area of traditional VHF radio stations.

Thus, users of the proposed utility model:

1) get rid of the need to build and maintain their own data transmission infrastructure for operational voice communications;

2) get the ability to flexibly configure user groups, even if they are located in different SPDs;

3) when replacing the radio stations with the proposed terminals, they do not need to be trained in their use, since the control elements and the user interface of the terminal are made in a simple manner similar to radio stations, despite a different operating principle;

4) get the opportunity to use the duplex mode of operation and additional functionality.

The foregoing descriptions are only preferred embodiments of the utility model, the use of which does not limit the present utility model. For those skilled in the art, the present utility model may have various changes and variations. Any changes, equivalent replacements, enhancements, etc. within the essence and principle of the present description and formula, all are within the scope of protection of the present utility model.

The industrial applicability of the utility model at the current level of technology development is real both in terms of using the utility model for the needs of dispatching and technological communications, and in terms of reproducing the design in industrial volumes. All components necessary for the implementation of the utility model are mass-produced, part in the form of discrete elements, and part in the form of ready-made functional modules. The bandwidth of existing wireless networks is sufficient to ensure the operation of the utility model. The need for operational wireless communications is confirmed by the fact that the industry mass-produces dozens of items of radio stations that have a similar purpose to the presented utility model, which are used in technological and dispatch communications in industry, transport, in the service sector and utilities.
