The invention relates to techniques for radio communication, and is intended for communication in one-and two-frequency simplex mode in radio networks for various purposes, mainly for communication between the control center and moving objects with the localization of moving objects in GLONASS/GPS and data transmission over the radio channel.

Currently, there are various communication systems with mobile objects, use wearable radio stations, mostly they transmit only voice signals. For the reception of navigational information additionally set the navigation receiver with navigation antenna, and to transmit information to the control station requires additional device - modem. When this dispatch station looks very bulky and significantly different from transportable radios. The disadvantages of the known systems is obvious, therefore, was developed radio, including radio and navigation receiver, and a transmission device navigation information over the air, all this became possible hardware and software methods that allow you to use one channel as a dispatcher and customer. This one dispatch station can be connected to several tens of subscriber RA is istance and constant monitoring.

Known radio (RF patent for useful model No. 56094 from 27.04.06,) containing the antenna, the receive path, the transmit path, the control module, keyboard, connected to the control module and the indicator. However, this radio does not provide safe and accurate reception of the speech signal.

Technical problem on which the invention is directed, is to expand the functions of the radio station, the possibility of combining up to several tens of subscriber stations on a single dispatch radio communication system and monitoring; implementation of the reception/transmission of navigational information via radio; security and privacy in the transmission of voice, as well as additional information on the status of subscriber radios.

This technical result is achieved by the communication system and monitoring, containing, at least, two radio stations, one of which is used as the control room and the other as a subscriber (portable) radios capable of transmitting/receiving a voice signal zaprogrammiruete frequency, the system provides separate reception speech signal on the same frequency using subsonic analog signal format CTCSS or DCS generated C is Provimi sequences, dispatch radio (DR) is connected to the computer through a connector System with control and monitoring incoming subscriber radios (AR), each radio contains the MB antenna range and manipulator, equipped with a DTMF keypad, navigation antenna, connected to a GPS receiver, and a block of sensors and actuators, communication between the subscriber and dispatch radio navigation information and information from the block of sensors and actuators is done via radio, and communication between the control room and subscriber stations available on the GSM channel.

The radio station may have a device for converting speech connected to the microprocessor unit and to provide protection for the received and transmitted voice data. The presence of intrusion switch the radio station provides timely notification of unauthorized opening of the case.

The invention is illustrated by drawings.

Figure 1 shows the block diagram of the communication and monitoring system.

Figure 2 presents the structural scheme of the station.

Communication system and monitoring, depicted in figure 1, contains a dispatch radio (DR) 1, connected to the computer 2 through the connector System 3 (e.g., DHS-44M), the antenna 4 MV-range navigation antenna 5 and the arm 6, N subscriber stations (AR) 7, each of which contains, as well as OTHERS 1: antenna 4 MV-range navigation antenna 5 and the arm 6, and is connected through a connector System 3 block sensors and actuators 8, consisting of analog and digital sensors (made in the present invention in the form of loops), the unit consists of a GSM modem.

The radio image is defined in figure 2, contains the management module 9 module transceiver path 10 and the automation module 11. The control module 9 contains the indicator 12, made in the form of liquid crystal screen and the keyboard 13. The manipulator 6, containing press the PTT switch, microphone and DTMF keypad (Fig. not shown), connected to the control module 9. Module transceiver path 10 includes: a navigation receiver 14, an input connected to the navigation antenna 5, and the output interface 15 RS-232 port designed for connection with external devices, the frequency synthesizer 16, 17 and the transmitting receiving 18 paths connected to the antenna 4 MV-range, low-frequency amplifier 19, one of the outputs of which is connected to a built-in speaker 20, and the other with the interface 15, and the intrusion switch 21 radio stations. The automation module 11 contains a microprocessor unit 22 that is connected to the block encoder/decoder 23, a device for converting speech 24 and a memory 25 for registration information, as well as its inputs/outputs connected to the control module 9, a navigation receiver 14, an interface 15, the frequency synthesizer 16, relays 17 and the receiving 18 tracts amplifier low frequency 19 and the chassis intrusion detector 21. Block encoding/decoding 23 second input/output connected to the speech-24, the first output amplifier nishikasai 19, second conveying path 17, and the input - receiving channel 18. Power to the radio is supplied through the connector System 3.

The proposed communication system and monitoring works in the following way. Each station can be programmed either as a dispatcher, or as a subscriber. OTHERS 1 is the base, i.e. controls and monitors the entire system program of the computer 2 dispatch center. It happens this way. With a certain interval from the computer 2 connected to OTHERS 1 through the connector System 3, enter the appropriate command (packet information). Upon receipt of this command, the microprocessor unit 22 reconstructs the frequency synthesizer 16 radio channel transmission of voice information on the data channel, then turns mode "Transmission"codes commands and transmits the appropriate command in error-correcting mode on AR 7 (same voice, only is the modulation of the transmitter of the digital information with redundant coding). Next mode "Transfer" is turned off, the radio goes into "Standby", and the frequency synthesizer 16 is rebuilt on the speech channel information. In the absence of a radio data transfer over GSM network using a GSM modem that is part of the Loka sensors and actuators 8 AR 7, and for OTHERS 1 this channel is via the computer 2.

AR 7 operate in the same manner. Each AR 7, when it is on the channel data, reports ETC 1 information about their individual room, information navigation receiver 14 and the condition of the unit sensors and actuators 8, is connected through a connector System 3, and receives (during reception is decoding the command, passed in error correcting mode) OTHERS 1 confirm and activate actuators.

Synchronizing the time on the channel data of all stations in the system are controlled by signals second label navigation receivers.

Block sensors and actuators 8 are in the form of loops (the present invention), which function as signaling. The radio station provides the tracking of the following loops: "Normal", "Alarm", "Break", "ground fault", "fault power".

The radio station operates as follows.

At power up the radio is initializing settings - set frequency stored working channel, the volume level of the threshold of the noise suppressor (TVs), step frequency grid, the brightness level of the backlight, the presence or absence of an audio message generated by the radio station, etc. is ri this microprocessor unit 22 checks the availability of a navigation receiver 14 and device for converting speech 25 and installs the corresponding modes of the radio station. Microprocessor unit 22 generates the initial information on the indicator 12, and then the radio goes into "Standby". In Standby reception" and "Receive" using the keyboard 13 of the control module 9 and the DTMF keypad of the manipulator 6 is reset modes the radio menu radio stations. Mode settings when connecting the radio to the computer 2 through the connector System 3 a setting that cannot be changed through the menu of the radio station, for example the frequency change of the working channel.

When working radio in all modes in the microprocessor unit 22 receives information from the GPS receiver 14 to the presence or absence of validity of the navigation information, current location, a single universal time (UTC). This information is displayed on the display 12 and may be issued to the external device via the connector System 3.

When in the air the speech signal for the programmed receiving frequency signal coming from the antenna 4 MV-band demodulated receiving channel 18, is processed by the block encoding/decoding 23 information and outputted through the low-frequency amplifier 19 speaker 20 or the external speaker through the connector System 3. If the received signal is below the plant and the threshold PSH, the speech signal to the internal speaker 20 and the loudspeaker is not transmitted. It is also possible to separate the reception speech signal for multiple stations on the same frequency when using subsonic analog signal format of the CTCSS tone or tone signals DCS generated digital sequences. In this case, the speech signal will be heard only when the received signal contains a component of the tone signal with the programmed frequency (format CTCSS) or sequence (DCS).

When you press the PTT switch of the pointing device 6, the radio goes into "transfer". On the display 12 displays the settings and status of the radio station in the "transfer" - the transmitter power level, SWR antenna tract. In this mode, the speech signal received from the microphone is processed by the block encoding/decoding 23 information transmission path 17 is modulated on the programmed transmit frequency, and then amplified to the required power level and is supplied to the antenna 4 MV range. Depending on the settings possible to transmit tone signals format CTCSS or DCS simultaneously send voice messages. Control the formation and decode tone signals are microprocessor components is.

The radio has a built-in memory unit 24 for the reception of navigational information and internal state radio and state block sensors and actuators 8 for a certain period of time. Count accumulated by the radio station information when the computer 2 through the connector System 3.
