Description

MOBILE INFORMATION TRANSMISSION SYSTEM

The technical solution relates to mobile radio communications, and in particular to systems for transmitting information to mobile objects.

A well-known personal radio call system (see, for example, Gromakov Yu.A. Standards and mobile radio communication systems. - M .: EcoTrendz, 2000, p. 10-52), containing a radio transmitter with a given radius of coverage, covering the served territory, and radios placed one at a time on each of the moving objects within the coverage area of the specified radio transmitter.

The specified system allows using one radio transmitter to transmit information to all mobile objects located within the served territory. However, when transmitting information to mobile objects located within a sufficiently vast served territory, a high-power radio transmitter must be used in the system, which worsens the environmental and economic performance of the system.

A well-known cellular radio communication system (see, for example, Ratinsky M.V. Basics of cellular communications. Edited by DB Zimin. - M .: Radio and communications, 2000, p.20-68), containing the first transceivers included in one of each of the base stations located in the centers of the conditional cells, which are equal regular hexagons, tightly spaced among themselves, densely covering the served territory, with the radii of the base station coverage areas equal to the length of each regular side

OBJECTS i of the hexagon, and with the transmission frequency of this base station specified on each of the base stations, which is one of seven different frequencies, different from the transmission frequencies of neighboring base stations, the reception frequencies of this base station, the second transceivers located one at each of the moving objects located within the coverage areas of all base stations with given transmission frequencies and reception frequencies of each second transceiver, and the given frequencies for the base station frequencies coincide with the set transmission frequencies of each second transceiver, which are different from any of the set transmission frequencies of the base stations, the set reception frequencies of each second transceiver are all seven set transmission frequencies of the base stations, the switching center, fiber-optic communication lines connecting the switching center to base stations. The specified system allows radio communication between mobile objects located within a sufficiently vast served territory, and, in particular, transmit information from one of the base stations, which is the source of the transmitted information, to these mobile objects. At the same time, relatively low-power first transceivers and second transceivers can be used in the system. However, to transfer information from the base station, which is the source of the transmitted information, to the base stations, in the areas of which these mobile objects are located, the system uses a switching center and fiber-optic communication lines connecting the switching center to base stations, which complicates the system. In this case, radio communication between base stations without the use of additional radio channels is impossible, since at given

Ј & (/

olWij the values of the radii of the zones of coverage of base stations and the parameters of the placement of base stations in the served territory, the distance between any two neighboring base stations is times the radius of the zones of their coverage. In addition, since the coverage areas of neighboring base stations overlap slightly, within the central sections of the coverage area of each base station, only radio signals of this base station can be received, and therefore the number of preset reception frequencies of each of the second transceivers located on moving objects cannot be less than seven, which also complicates the system. Along with this, with the given values of the radii of the coverage areas of base stations and the placement parameters of base stations in the served territory, the system does not allow the reception of these information radio signals at neighboring base stations when measuring information radio signals from each base station, measuring their power and adjusting at each base station the power of the emitted information radio signals according to the measured power values, which leads to a decrease in the quality of information reception at moving objects When you change the radii of the zones of the base station due to a change of radio wave propagation conditions.

The term “moving object is generally accepted. (See, for example, Solovyov, Yu.A. Satellite navigation systems. - M .: Ekotrendz, 2000, p. 47.) Mobile objects include, for example, various vehicles equipped with radio reception equipment. By the terms “neighboring base station or” a base station that is adjacent to a given base station, we mean base stations located at the closest distance from this base station. In FIG. 1 depicts conditionally base stations located on the served territory and mobile objects located within the served territory, with a conditional image of the coverage areas of the base stations and an indication of the specified operating frequencies of the radio signals emitted from each of these base stations, for the case in which the number of base Stations is seventy-two; the number of mobile objects is five. In FIG. 2 shows a system for transmitting information to moving objects for the case in which one first transceiver is part of a base station that is a source of transmitted information, the number of second transceivers that are one each of the base stations that are not sources of transmitted information is eighteen, and the number of radios placed one on each of the moving objects is three, and the moving objects in FIG. 2 not shown. FIG. 3 shows the first transceiver included in the base station, which is the source of the transmitted information, and the base station, which is the source of the transmitted information, in FIG. 3 is not shown.

In the present description, the following notation is used. 1 „- base station 1 with number n, where n 1,2, ..., W are positive integers; 2t - movable object 2 with number t, where t 1,2, ..., M are positive integers; 3 „- zone 3 of the action of the base station 1„; fq is the working frequency of the radio signals emitted from base station 1, where q 1,2, ..., 2 are positive integers. In cases where this does not lead to misinterpretation, the indices in the above notation are omitted. The essence of the technical solution is as follows. On the served territory, in the centers and at the vertices of the conditional cells, which are equal regular hexagons, densely covering the served territory, are placed, as shown in FIG. 1, base stations 1 (base stations -) and base stations 12o - b3, respectively), the radii of zones 3 of which are set equal to the length of the side of each regular hexagon. With this arrangement of base stations 1 on the served territory, no more than six base stations 1 are adjacent to each base station 1.

 (о syy With this arrangement of base stations 1 on the served territory, no more than six base stations 1 are adjacent to each base station 1. By zone 3 of action of each base station 1 we mean equal zone 3 of action when radiating radio signals from this base station 1 and zone 3 of the action when receiving radio signals at this base station 1. Moreover, under zone 3 of the action when radiating radio signals from each base station 1 we understand the part of the territory within which, with undirected radiation from this base of station 1 of radio signals of power PqW3Sl at an operating frequency fq, the power of these radio signals when they are received at other base stations 1 and on mobile objects 2, is not less than a certain threshold value of -Prmin, which characterizes the sensitivity of the channels of radio signals reception at base stations 1 and on mobile objects 2 Under action zone 3 when receiving radio signals at each base station 1, we mean a part of the territory within which, with undirected radiation from other base stations 1, radio signals of the same power Pqmn to at the same operating frequency fq, the power of these radio signals during non-directional reception at this base station 1 is not less than the same value of prmin.In this regard, assuming that the propagation of radio waves occurs in free space, and the served area is a plane, zone 3 of each base station 1 with the non-directional radiation from base stations 1 and the non-directional reception of radio signals at base stations 1 and mobile objects 2 is a circle centered at the location of this base station 1 and the radius determined by the formula (see, for example, Theoretical fundamentals of radar. Soviet Radio, 1978, p. 422) W, A / 4 Kprmin where c is the speed of light in vacuum. By the radius of the zone 3 of the action of each base station 1 we understand the radius of the specified circle. When placing base stations 1 in the centers and at the tops of conditional cells, which are equal regular hexagons that densely cover the served territory, with radii of zones 3 of action of base stations 1 equal to the length of the side of each regular hexagon, the border of zone 3 of action of each base station 1 passes through placement points of neighboring base stations 1. In FIG. 1 boundaries of zones 3 of the operation of base stations 1 are shown conditionally by circles. In the present description, by the term “signal power, we mean the average signal power P signal s (t), determined in the time interval ta t tb by the formula (see, for example, AM Trakhtman. Introduction to the generalized spectral theory of signals. - M.: Soviet radio, 1972, p.14) P) dt. (2) b-gaga The system uses information and service radio signals. If in the present description the type of radio signals is not specified, then they can be both information and service radio signals. Set and stabilize seven different operating frequencies (Q l) of the radio signals emitted from all base stations 1. Of the seven set operating frequencies at each base station 1, set as Ed. V.E. Dulevich. - M .:

um ko7gg1 is shown in FIG. 1, one operating frequency of the radio signals emitted from this base station 1, different from the set operating frequencies of the radio signals emitted from neighboring base stations 1. Thus, at base stations 1 that are not adjacent, the repeating operating frequencies of the radio signals emitted from these base stations 1. By the term "operating frequency, we mean the value of the frequency of the carrier wave, the central or some other characteristic value of the frequency of the frequency band of radio signals. Moreover, the frequency bands of the radio signals corresponding to different operating frequencies are non-overlapping. Information signals corresponding to information transmitted to mobile objects 2 located within the served territory are transmitted from one of the base stations 1, which is the source of the transmitted information, to base stations 1, in the zones of action 3 of which mobile objects 2 are located. From these base stations 1 carry out the emission of information radio signals corresponding to the transmitted information. In this case, information signals corresponding to information transmitted to mobile objects 2 located within the service area are the corresponding information radio signals. The transmission of information radio signals from the base station 1, which is the source of the transmitted information, to the base stations 1, in the zones of action 3 of which are moving objects 2, is as follows. From the base station 1, which is the source of the transmitted information, radiation of information radio signals is carried out at a given operating frequency. Moreover, at all base stations 1, which are adjacent to base station 1, which is i

13 as the source of the transmitted information, simultaneously receive the information radio signals transmitted from the last base station 1 and their radiation at the corresponding preset operating frequencies. Then, at all other base stations 1, which are adjacent to the indicated base stations 1, information radio signals emitted from the indicated base stations 1 are simultaneously received and emitted at the corresponding preset operating frequencies. Then, in the same way, sequentially, in all directions from the base station 1, which is the source of the transmitted information, to the boundaries of the served territory at all other subsequent base stations 1, which are adjacent to the previous base stations 1, simultaneously receive signals transmitted from the previous base stations 1 information radio signals and their radiation at the corresponding specified operating frequencies. To ensure the transmission of informational radio signals from the base station 1, which is the source of the transmitted information, to the base stations 1, in zones 3 of which there are movable objects 2, and, therefore, to all other base stations 1, without “looping at each base station 1 , in addition to the base station 1, which is the source of the transmitted information, set the operating frequencies of the information radio signals received at this base station 1, at which the information radio is emitted from this base station 1 signals at a given operating frequency. With the indicated placement parameters on the served territory of base stations 1 with the specified radii of action zones 3, at least three action zones of neighboring base stations 1 overlap at each point of the served territory 1. Since the radiation of informational radio signals from neighboring base stations is 1-h,

2W LUs are carried out at different operating frequencies, at each receiving point information radio signals of at least three different preset operating frequencies are received. Therefore, to ensure guaranteed reception of informational radio signals on moving objects 2 when they move within the service area, it is sufficient to receive informational radio signals on each moving object 2 at only five different out of seven specified operating frequencies. Mobile objects 2 receive informational radio signals emitted from base stations 1, in the zones 3 of which these mobile objects 2 are located. At the same time, informational radio signals are received on mobile objects 2 at specified operating frequencies, which are five different on each mobile object 2 from seven set working frequencies. To ensure the operability of the system, the placement of base stations 1 near the boundaries of the served territory must be carried out so that at each point of the served territory there is an overlap of at least three zones 3 of the activity of neighboring base stations 1. Thus, for example, the border of the served territory shown in FIG. 1, it can be a closed polygonal line passing through all the extreme base stations 1 (base stations 12o, h4, hi, hs, h2, bb, bo, bb, Uo, 146, 152, b, 1b2, 1bb,, 1b9, 1b8 , U, 1bZ, bb, bb, 147, Ub bb, bb, bb) When transmitting information to moving objects 2 under conditions of propagation of radio waves in free space to provide a given value of radius R of zone 3 of action of each base station 1 at known values of the working frequency fq and sensitivity Рш, channels for receiving radio signals, it is necessary in accordance with formula (1) to provide the required value of power and PqK3Jl emitted

informational radio signals. However, when the propagation conditions of radio waves deteriorate, which occurs, for example, when the base stations 1 are shaded and when the radio waves attenuate in the atmosphere, the radius of the zones 3 of the base stations 1 decreases, which leads to a decrease in the quality of information reception at moving objects 2. Therefore, to ensure the required quality receiving information on moving objects 2 at each base station 1, it is necessary to adjust the power of the emitted information radio signals. At each base station 1, the power of information radio signals received from neighboring base stations 1 is measured. Then, overhead radio signals containing information about the measured power values are emitted from each base station 1. At each of these neighboring base stations 1, the above-mentioned radio signals are received and the power of the emitted information radio signals is adjusted according to the measured values of the power of information radio signals received at the base stations 1, which are adjacent to the indicated neighboring base station 1, and emitted from this base station 1 The power control of the emitted information radio signals at each of these neighboring base stations 1 is carried out, for example, by the minimum value m generality of the measured values of the power information radio signals received at the base stations 1, which are adjacent to said adjacent base station 1, and emitted from the base station 1, using the formula RR

where meas.min is the minimum power value from the corresponding measured power values of the information radio signals; Pqmu is the power value of the radiated information radio signals, which is set at the base station 1 in the process of adjustment according to the measurement results; 1 - coefficient determining the margin for

sensitivity and power adjustment range of radiated information radio signals.

Formula (3) shows that at each base station 1 in the process of adjusting the power of the radiated information radio signals

 i / When temporarily separating the information and service radio channels at each base station 1, the specified operating frequencies of the radio signals are used to emit the service radio signals. In this case, the radiation of information and service radio signals is carried out at various points in time. At each base station 1, except for the base station 1, which is the source of the transmitted information, stabilization of the set operating frequency of the emitted radio signals is carried out according to the working frequency of one of the radio signals received at this base station 1, at which the information radio signals are emitted from this base station 1 at the preset operating frequency. Set at each base station 1, except for base station 1, which is the source of the transmitted information, the operating frequencies of the radio signals received at this base station 1, at which

17 of this base station 1 carry out the emission of information radio signals at a given operating frequency, make it possible to transmit information radio signals from the base station 1, which is the source of the transmitted information, to base stations 1, in the zones of action 3 of which are moving objects 2, and, therefore, all other base stations 1, without looping. Therefore, stabilization of the working frequency of the radio signals emitted from each base station 1, except for the base station 1, which is the source of the transmitted information, is carried out as a result of the working frequency of the radio signals emitted from the base station 1, which is the source of the transmitted information. The stabilization of the operating frequency of the radio signals emitted from the base station 1, which is the source of the transmitted information, is carried out, for example, by the frequency of highly stable reference oscillations generated at this base station 1. The system for transmitting information to moving objects 2 is shown in FIG. 2. The system comprises a first transceiver 4, which is part of the base station 1, which is the source of the transmitted information, second transceivers 5, which are one each of the base stations 1, which are not the sources of the transmitted information, radios 6, placed one on each of 2 mobile objects located within the serviced territory. In FIG. 2, an example is shown of a system comprising one first transceiver 4, eighteen second transceivers 5 and three radio receivers 6. In this case, a description of the system and operation of this system is given for an arbitrary number of second transceivers 5, one each of which is included in each of the base stations 1, not being sources of transmitted information, and radios 6, placed one on each of

leajtol & y movable objects 2 within the boundaries of the served territory. All base stations 1 are located in the centers and at the vertices of the conditional cells, which are equal regular hexagons, densely spaced among themselves, densely covering the served territory. The radius of the zone 3 of action of each base station 1 is set equal to the length of the side of each regular hexagon. At each point of the served territory, at least three zones of operation of neighboring base stations 1 overlap. The transmission frequency of base station 1 is the corresponding operating frequency of the radio signals emitted from this base station 1. The receiving frequency of radio receiver 6 is the corresponding operating frequency of information radio signals received on the corresponding mobile object 2. The terms "transmission frequency and" frequency of reception of any device are generally accepted. (See, for example, Gromakov Yu.A. Standards and mobile radio communication systems. - M: Eco-Trends, 2000, p.22.) Of the seven different operating frequencies set at each base station 1, the transmission frequency of this base station 1 is set, different from the specified transmission frequencies of neighboring base stations 1. Of the seven specified operating frequencies on each mobile object 2, five different reception frequencies of a radio receiver 6 located on this mobile object 2 are set. All elements and blocks included in the system are known and described in literature.

All base stations 1, which are not sources of transmitted information, contain the same second transceivers 5, differing only in the frequency values for which the second bandpass filters 21 are tuned. A radio receiver 6 located on each moving object 2 shown in FIG. 5, contains a third receiving antenna 39, five channels for receiving radio signals, each of which contains a third band-pass filter 40, a third low-noise amplifier 41, a third amplitude detector 42, a third squaring unit 43, a third integrator 44, and a third ADC 45. The radio receiver 6 comprises also the third microcontroller 46, indicator 47. The output of the third receiving antenna 39, designed for omnidirectional reception of information radio signals emitted from base stations 1, is connected to the inputs of all third bandpass filters 40, which are used for lecture information on radio frequency.

The third squaring unit 43 and the third integrator 44 are connected in series to generate signals proportional to the power of the received radio signals. The output of the third integrator 44 is connected to the input of the third ADC 45. The outputs of all third amplitude detectors 42 and the outputs of all third ADC 45 are connected to the corresponding inputs of the third microcontroller 46, designed to process the information received from base stations 1 and display it on the indicator 47, the inputs of which are connected to the outputs of the third microcontroller 46. On all moving objects 2 are the same type of radio receivers 6, and the operating frequencies, which are tuned to the third band-pass filters 40, can be different mobile objects 2. At the base station 1, which is the source of the transmitted information, at other base stations 1 and mobile objects 2, such values of the amplification factors of the first low-noise amplifiers 9, second low-noise amplifiers 22 and third low-noise amplifiers 41, at which the channel sensitivity reception of radio signals at base stations 1 and at mobile objects 2 is equal to min- At base station 1, which is the source of the transmitted information, and at other base stations 1, the initial depending on the specified values of the operating frequencies fq of the radio signals emitted from these base stations 1, respectively, such values of the power gains of the first adjustable power amplifier 16 and the second adjustable power amplifiers 35 (during operation of the system these values can be changed), at which the values of the power of information radio signals emitted from these base stations 1 are equal to RFNL, respectively. In this case, the values of Rptia and the value of Rprmin are selected based on a given value of the radius of the zone 3 of action of each base station 1, equal to the length of the side of each of these regular hexagons. Information and service radio signals are narrowband; the propagation time of radio signals from each base station 1 to neighboring base stations 1 and the time interval for measuring the power of the received radio signals are negligible compared to the duration of any of the pulses of modulating binary pulse sequences corresponding to information transmitted to moving objects 2, as well as service information; the propagation time of signals in the transceiver paths of base stations 1 is negligible. The accepted assumptions correspond, for example, to the following system parameters. The radius of zone 3 of action of each base station 1 is 500 m; the working frequencies of the radio signals emitted from all base stations 1 are respectively 11, 12, 13, 14, 15, 16 and 17 MHz; the duration of any of the pulses of modulating binary sequences of pulses corresponding to information transmitted to moving objects 2, as well as service information, at least 10 ms, the time interval for a single measurement of the power of the received radio signals is not more than 0.1 ms. Consider the operation of the system shown in FIG. 2. At the base station 1, which is the source of the transmitted information, to the first block 19 of the job of the first transceiver 4, shown in FIG. 3, information intended for transmission to mobile objects 2 is inputted. At each base station 1, which is not a source of transmitted information, into the second unit 38 of the second transceiver 5 shown in FIG. 4, from seven preset operating frequency values, a preset value of the operating frequency of the radio signals emitted from this base station 1 is entered, different from the preset values of the operating frequency of the radio signals emitted from neighboring base stations 1, as well as the values of the operating frequency of the radio signals received at this base station 1 , in which from this base station 1 carry out the emission of information radio signals at a given operating frequency. The system operates alternately in two modes: the mode "Information transfer to moving objects 2 (main mode) and the mode" Adjusting the radiation power of base stations 1 (service mode). At the base station 1, which is the source of the transmitted information, the first microcontroller 18 leads the first

the transceiver 4 in the mode "Information transfer to mobile objects 2. At each of all other base stations 1, the second microcontroller 37 sets the second transceiver 5 in the mode" Information transfer to mobile objects 2.

At the base station 1, which is the source of the transmitted information, the first microcontroller 18 reads in binary code from the first job block 19 information intended for transmission to moving objects 2. Then, the first microcontroller 18 generates a resulting binary code containing a binary code corresponding to the information transmitted to movable objects 2, and a binary code attached to it containing a sign of the end of the information radio signal. Then, the first microcontroller 18 generates a binary pulse train corresponding to the resulting binary code at the low-frequency input of the first amplitude modulator 15. Simultaneously at the high-frequency input of the first amplitude modulator 15, highly stable reference oscillations of one of seven predetermined operating frequencies are generated by the reference oscillator 14. The first amplitude modulator 15 generates a high-frequency amplitude-modulated signal with a modulation coefficient A / 0.5. This signal is fed to the input of the first adjustable power amplifier 16, from the output of which the amplified signal is fed to the input of the first transmitting antenna 17. The first transmitting antenna 17 emits into the space an informational radio signal thus formed, corresponding to information transmitted to moving objects 2. The radiated informational radio signal ends a sequence of radio pulses containing a sign of the end of the information radio signal.

 ((ft SYy) The reception of the information radio signal emitted from the base station 1, which is the source of the transmitted information, is carried out at neighboring base stations 1 using the second transceivers 5 contained in them, shown in Fig. 4. In this case, the second receiving antenna 20, which is part of of each of these second transceivers 5, receives an informational radio signal emitted from the base station 1, which is the source of the transmitted information. The received informational radio signal is fed to the inputs of all the second bands output filters 21. At each base station 1, which is adjacent to the base station 1, which is the source of the transmitted information, at the output of one of the second bandpass filters 21, tuned to the operating frequency of the radio signals emitted from the base station 1, which is the source of the transmitted information, a high-frequency amplitude-modulated signal with a modulation coefficient of M 0.5 corresponds to the received informational radio signal. This signal is fed to the input of the second low-noise amplifier 22, from the output of which the signal is fed to the input of the second amplitude detector 24 and to the input of the amplitude limiter 23, which selects the carrier oscillation of the received amplitude-modulated information radio signal. The second amplitude detector 24 performs amplitude detection of the received information radio signal and generates a binary sequence of pulses corresponding to the transmitted information. These signals are fed to one of the switched inputs of the first electronic switch 28 and to the input of the second microcontroller 37. At the same time, the signal from the output of the amplitude limiter 23 goes to the corresponding switched input of the second et /

electronic switch 29 and the input of the second block 25 of the squaring. From the output of the second squaring unit 25, the signal is fed to the input of the second integrator 26, which, at the input of the second ADC 27, generates in accordance with formula (2) a signal proportional to the power of the received information radio signal. The digital code from the outputs of the specified second ADC 27 is supplied to the inputs of the second microcontroller 37. The second microcontroller 37 determines by the digital code acting at the output of the specified second ADC 27 and the known value of the gain of the corresponding channel for receiving radio signals the power of the received information radio signal Rsch. The second microcontroller 37 checks the condition R prmin, where Kzap 1.2, and in case of its fulfillment, makes a decision on the presence of the information radio signal of the corresponding operating frequency at the input of the second transceiver 5, otherwise the second microcontroller 37 takes the opposite decision. (Kzap coefficient 1.2 provides a margin of sensitivity necessary for measuring the power of received information radio signals when the propagation conditions of the radio waves deteriorate and insufficient for receiving radio signals from remote base stations 1.) Then, the second microcontroller 37 reads from the second block 38 of the job the specified value of the operating frequency of the information radio signals, radiated from this base station 1, as well as the set values of the operating frequencies of the information radio signals received at this base station 1, p and with which the base station 1 is carried out radiation of radio information at a given operating frequency, and determines the set values for these operating frequencies and signal values, acting on the respective second outputs of the ADC 27, W

operating frequency of the information radio signal of maximum power. (At each base station 1, which is adjacent to the base station 1, which is the source of the transmitted information, the operating frequency of the maximum power information radio signal thus determined is the operating frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information.) Second microcontroller 37 generates control signals at the control inputs of the first electronic switch 28, which connects the output of the second amplitude detector 24, corresponding to the operating frequency of the maximum power information radio signal, to the low-frequency input of the second amplitude modulator 34 The second microcontroller 37 also generates control signals at the control inputs of the second electronic switch 29, which connects the output of the amplitude limiter 23, corresponding to the working frequency of the maximum power information radio signal, to the first input of the phase detector 30. At the same time, the second microcontroller 37 determines the desired value, the ratio of the coefficients of affairs the first frequency divider 32 and the second frequency divider 33 according to the formula controlled by the generator 31 and the first frequency divider 32. (See, for example, Theoretical Foundations of Radar. Edited by V.E. Dulevich. M: Soviet Radio, 1978, p. 358). The second microcontroller 37 generates control signals at the control inputs of the first frequency divider 32 and the second frequency divider 33, by which their division coefficients take the values K} and K2, satisfying the relation obtained by formula (4). As a result of this, frequency / max signals act on both inputs of the phase detector 30, the controlled generator 31 generates frequency oscillations K} / max, the second frequency divider 33 divides this frequency by K2 times and receives oscillations of a given operating frequency /, the stability of which is determined by the stability of the operating frequency information radio signals emitted from the base station 1, which is the source of the transmitted information. The stability of the latter is determined by the stability of the frequency of highly stable oscillations generated by the reference generator 14 of the base station 1, which is the source of the transmitted information. At various base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, the obtained values of the ratio of the division coefficients of the first frequency divider 32 and the second frequency divider 33 are generally different. The signal from the output of the second frequency divider 33 is fed to the high-frequency input of the second amplitude modulator 34, the low-frequency input of which receives a binary pulse train acting at the output of the specified second amplitude detector 24. The second amplitude modulator 34 generates a high-frequency amplitude-modulated signal with a modulation coefficient M 0.5. This signal is fed to the input of the second

la ftf & fl of an adjustable power amplifier 35, the output of which the amplified signal is fed to the input of the second transmitting antenna 36. The second transmitting antenna 36 emits into the space an informational radio signal thus formed corresponding to the information transmitted to the moving objects 2. The radiated informational radio signal also ends with a sequence of radio pulses, containing a sign of the end of the information radio signal. Thus, the stabilization of the operating frequencies of the information radio signals emitted from each of the base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, is carried out at the operating frequency of one of the received information radio signals, at which radiation is emitted from this base station 1 information radio signals at a given operating frequency. At each of these base stations 1, the indicated operating frequency of one of the received information radio signals is the operating frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information. The information radio signals emitted from these neighboring base stations 1 are received at the base stations 1 that are adjacent to the indicated neighboring base stations 1, using the second transceivers 5 contained in them, shown in FIG. 4. In this case, the second receiving antenna 20, which is part of each of these second transceivers 5, receives information radio signals emitted from these neighboring base stations 1. Received information radio signals are received at the inputs of all second band-pass filters 21. At each base station 1, which is adjacent to the base station 1, which is the source of the transmitted information, at the output of the second band-pass filters 21, high-frequency amplitudes corresponding to the received information radio signals itudno-modulated signals with a modulation factor M 0.5. These signals are fed to the inputs of the second low-noise amplifiers 22, from the outputs of which the signals are fed to the inputs of the second amplitude detectors 24 and to the inputs of the amplitude limiters 23, which emit carrier vibrations of the received amplitude-modulated information radio signals. The second amplitude detectors 24 perform amplitude detection of the received information radio signals and generate binary pulse sequences corresponding to the transmitted information. These signals are fed to the corresponding switched inputs of the first electronic switch 28 and to the corresponding inputs of the second microcontroller 37. At the same time, the signals from the outputs of the amplitude limiters 23 are fed to the corresponding switched inputs of the second electronic switch 29 and to the corresponding inputs of the second squaring blocks 25. From the outputs of the second squaring blocks 25, the signals are fed to the inputs of the second integrators 26, which at the inputs of the second ADCs 27 form signals in accordance with formula (2) that are proportional to the power values of the received information radio signals. Digital codes from the outputs of the second ADCs 27 are fed to the inputs of the second microcontroller 37. The second microcontroller 37 determines from the digital codes acting on the outputs of the second ADCs 27 and the known gain values of the corresponding channels for receiving radio signals, the power values Rp of the received information radio signals. To carry out the verification of the condition R × execution makes a decision on the presence at the input of the second transceiver 5 of the information radio signal of the corresponding operating frequency, otherwise the second microcontroller 37 takes the opposite decision. Then, the second microcontroller 37 reads from the second set unit 38 the set value of the operating frequency of the information radio signals emitted from this base station 1, as well as the set values of the operating frequencies of the information radio signals received at this base station 1, in which information from this base station 1 radio signals at a given operating frequency, and determines from these given values of the working frequencies and the values of the signals acting on the outputs of the corresponding second ADCs 27, the working often that information signal of maximum power. The second microcontroller 37 generates control signals at the control inputs of the first electronic switch 28, which connects the output of the second amplitude detector 24, corresponding to the operating frequency of the maximum power information radio signal, to the low-frequency input of the second amplitude modulator 34. The second microcontroller 37 also generates control signals at the control inputs of the second electronic switch 29, which connects the output of the amplitude limiter 23, corresponding to the operating frequency of the information nnogo radio maximum power to the first input of the phase detector 30. Simultaneously, a second microcontroller 37 determines the required value of the ratio of division of the coefficients of the first frequency divider 32 and second frequency divider 33 by the formula (4). The second microcontroller 37 generates control signals at the control inputs of the first frequency divider 32 and prmin, where LGMP 1.2, and in the case of its second w frequency divider 33, according to which their division coefficients take values that satisfy the ratio obtained by formula (4). As a result of this, at the output of the second frequency divider 33, oscillations of a predetermined operating frequency / ass operate, the stability of which is determined by the stability of the operating frequency of one of the information radio signals emitted from base stations 1, which are adjacent to base station 1, which is a source of transmitted information. The signal from the output of the second frequency divider 33 is fed to the high-frequency input of the second amplitude modulator 34, the low-frequency input of which receives a binary pulse train acting at the output of the specified second amplitude detector 24. The second amplitude modulator 34 generates a high-frequency amplitude-modulated signal with a modulation coefficient M 0.5. This signal is fed to the input of a second adjustable power amplifier 35, from the output of which the amplified signal is fed to the input of the second transmitting antenna 36. The second transmitting antenna 36 emits into the space the thus generated information radio signal corresponding to the information transmitted to the moving objects 2. The radiated information radio signal is also ends with a sequence of radio pulses containing a sign of the end of the information radio signal. Thus, at each of the base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, stabilization of the operating frequency of the emitted information radio signals is carried out according to the operating frequency of one of the information radio signals received at this base station 1, at which base station 1 carry out the emission of information radio signals at a given operating frequency. At each of these base stations 1, the indicated operating frequency of one of the received information radio signals is the operating frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information. By analogy with the above, all the second transceivers 5, which are part of all other base stations 1, operate. The information radio signals emitted from each base station 1 penetrate through the second receiving antennas 20 to the inputs of the second transceivers 5 included in these base stations 1. However, this does not cause a "looping of the system, since the radiation of information radio signals from each base station 1, except for base station 1, which is the source of the transmitted information, is carried out only when receiving 1 of the base station radio signal information from one given on the base station 1 operating frequencies. In this case, the radiation of information radio signals from the base station 1, which is the source of the transmitted information, is carried out regardless of the operation of neighboring base stations 1. With a sufficiently high speed of the described elements and blocks, we can assume that the second transceivers 5, which are part of the base stations 1, carry out simultaneously the reception of information radio signals emitted from neighboring base stations 1 and their emission at the corresponding predetermined operating frequencies. By analogy with the above, the second transceivers 5, which are part of all other base stations 1, operate in the “Information transfer to mobile objects 2” mode. At each base station 1, which is not a source of transmitted information, the second microcontroller 37 also reads the signals from the outputs of all the second ADC 27 and remembers the values of the power of informational radio signals emitted from all neighboring base stations 1 in the mode “Information transfer to mobile objects 2. Similar to the one described above at base station 1, i using the first receiving antenna 7, the first band-pass filters 8, the first low-noise amplifiers 9, the first And squaring blocks, the first integrators 12, the first ADCs 13 and the first microcontroller 18 in the mode of "Information transfer to moving objects 2 is carried out reception and processing of information radio signals emitted from all neighboring base stations 1. In this case, the first microcontroller 18 also reads the signals from the outputs of all first ADCs 13 and stores information power values from them radio signals emitted from all neighboring base stations 1 in the "Information transfer to mobile objects 2. mode. Thus, the second transceivers 5 included in the base stations 1, in accordance with the information contained in the second blocks 38 of the job, sequentially, for all directions from the base station 1, which is the source of the transmitted information, to the boundaries of the served territory at all other subsequent base stations 1, which are adjacent to the previous base stations 1, carry out one TERM receiving radiated from the previous base station 1 information and radio radiation at respective predetermined operating frequencies. Moreover, at each base station 1, except for the base station 1, which is the source of the transmitted information, stabilization of the specified operating frequencies of the emitted information radio signals is stabilized by the operating frequency of one of the radio signals received at this base station 1, at which information is emitted from this base station 1 radio signals at a given operating frequency. At each moving object 2 located within the service area, a third receiving antenna 39, which is part of the radio receiver 6 shown in FIG. 5, receives informational radio signals emitted from base stations 1, in the action zones 3 of which this moving object 2 is located. These signals from the output of the third receiving antenna 39 are fed to the inputs of the third band-pass filters 40, which select them in frequency. The signals from the outputs of the third band-pass filters 40 are fed to the inputs of the third low-noise amplifiers 41, the signals from the outputs of which are fed to the inputs of the third amplitude detectors 42, which perform amplitude detection of the received information radio signals. The binary sequences of pulses generated by the third amplitude detectors 42 are fed to the inputs of the third microcontroller 46. At the same time, the signals from the outputs of the third low-noise amplifiers 41 are fed to the inputs of the third squaring blocks 43, the output signals of which are fed to the inputs of the third integrators 44, which are at the inputs of the third ADCs 45 form in accordance with formula (2) the signals proportional to the power of the received information radio signals. The digital codes from the outputs of the third ADC 45 are supplied to the inputs of the third microcontroller 46. The third microcontroller 46 determines by the digital codes acting on the outputs of the third ADC 45, and the known values of the gain of the corresponding channels for receiving radio signals, power values / received W

(If the propagation conditions of the radio waves deteriorate, the decrease in the power of the received information radio signals is compensated by an increase in the power of the information radio signals emitted from neighboring base stations 1, which is carried out in the "Adjusting the radiation power of base stations 1." mode. Then, the third microcontroller 46 processes the binary pulse sequences acting on the outputs of the corresponding third amplitude detectors 42, and generates signals at the inputs of indicator 47, by which indicator 47 displays information the transmitted to mobile objects 2. Mode “Adjusting the radiation power of base stations 1. After the radiation of the next informational radio signal at base station 1, which is the source of the transmitted information, the first microcontroller 18 sets the first transceiver 4 to the mode“ Adjusting the radiation power of base stations 1. In this case, the first microcontroller 18 generates at the low-frequency input of the first amplitude modulator 15 a binary sequence of pulses containing service information about the measured and stored during the previous regime, "Transmission of information on the moving objects 2 power values of the received information signals. Simultaneously at the high-frequency input of the first amplitude modulator 15, highly stable reference oscillations of one of the seven specified operating frequencies are generated by the reference oscillator 14. The first amplitude modulator 15 generates a high-frequency amplitude-modulated signal with a factor of h

This signal is fed to the input of the first adjustable power amplifier 16, from the output of which the amplified signal is fed to the input of the first transmitting antenna 17. The first transmitting antenna 17 emits into the space the thus generated service radio signal containing information about the measured values of the power of informational radio signals received at base station 1 , which is the source of the transmitted information. At each of the base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, at the end of the reception of the next informational radio signal, the second microcontroller 37 leads (as a result of identification by the second microcontroller 37 of the sequence of radio pulses containing the termination of the informational radio signal) the second transceiver 5 in the mode "Adjusting the radiation power of base stations 1 In this case, the second microcontroller 37 forms on the control inputs of the first of the electronic switch 28, the control signals by which the first electronic switch 28 disconnects the outputs of the second amplitude detectors 24 from the low-frequency input of the second amplitude modulator 34 and connects to it one of the outputs of the second microcontroller 37 At the same time, at each of these neighboring base stations 1, the second receiving antenna 20 receives service radio signals emitted from base stations 1 that are adjacent to said neighboring base stations 1 Received radio service signals are transmitted to the inputs of the second band-pass filters 21, which select them by frequency. At the outputs of the second band-pass filters 21, high-frequency amplitude-modulated signals with a modulation coefficient of M 0.5 correspond to received service radio signals. These signals from the outputs of the second low-pass filters 21 are fed to the inputs of the first low-noise amplifiers 22.

Then, the second microcontroller 37 will determine, using formula (3), the required value of the power Rschl of the radiated information radio signals and generates a control signal at the control input of the second adjustable power amplifier 35, according to which the power of the radiated information radio signals takes the value Pqyasi. At the same time, the signals from the outputs of the second low-noise amplifiers 22 are fed to the inputs of the amplitude limiters 23, which emit the carrier oscillations of the received amplitude-modulated service radio signals. The signals from the outputs of the amplitude limiters 23 are fed to the switched inputs of the second electronic switch 29 and to the inputs of the second squaring blocks 25. From the outputs of the second squaring blocks 25, the signals are supplied to the inputs of the second integrators 26, which at the inputs of the second ADCs 27 form signals in accordance with formula (2) that are proportional to the power of the received service radio signals. The signals from the outputs of the second ADC 27 are fed to the inputs of the second microcontroller 37. The second microcontroller 37 reads from the second block 38 of the job the set value of the operating frequency of the radio signals emitted from this base station 1, as well as the set values of the operating frequencies of the radio signals received at this base station 1, in which from this base station 1 they carry out the emission of information radio signals at a given operating frequency, and determines from these given values of the operating frequencies and the values of the signals acting on the outputs of the co corresponding second ADC 27, the operating frequency of the service radio signal of maximum power. (At each base station 1, which is adjacent to base station 1, which is the source of the transmitted information, the operating frequency of the service radio signal of maximum power thus determined is the working frequency of the service radio signals emitted from the base station 1, which is the source of transmitted information.) Second the microcontroller 37 generates control signals at the control inputs of the second electronic switch 29, which connects the output of the amplitude limiter 23, corresponding the working frequency of the service radio signal of maximum power, to the first input of the phase detector 30. At the same time, the second microcontroller 37 determines the required value of the ratio of the division factors of the first frequency divider 32 and the second frequency divider 33 according to the formula (4), where / max is now the working frequency of the service radio signal of maximum power . The second microcontroller 37 generates control signals at the control inputs of the first frequency divider 32 and the second frequency divider 33, according to which their division coefficients take values K1 and K2, which satisfy the relation obtained by formula (4). As a result of this, frequency / mu signals act on both inputs of the phase detector 30, the controlled generator 31 generates frequency oscillations ATj / MaKC, the second frequency divider 33 divides this frequency by K2 times and receives oscillations of a given operating frequency /, hell, the stability of which is determined by the stability of the working frequency service radio signals emitted from the base station 1, which is the source of the transmitted information. The stability of the latter is determined by the stability of the frequency of highly stable oscillations generated by the reference generator 14 of the base station 1, which is the source of the transmitted information. (Obtained in this mode, “Adjusting the radiation power of base stations 1, the value of the operating frequency of the service radio signal of maximum power and the division coefficients of the first frequency divider 32 and the second frequency divider 33 in the general case may not coincide respectively with the values of the operating frequencies of information and service radio signals of maximum power and with the values of the division coefficients of the first frequency divider 32 and the second frequency divider 33, obtained in the modes "Information transfer to moving objects you 2 or in other modes “Adjusting the radiation power of base stations 1.) At various base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, the obtained values of the ratios of the division coefficients of the first frequency divider 32 and the second frequency divider 33 in Generally different. The signal from the output of the second frequency divider 33 is fed to the high-frequency input of the second amplitude modulator 34, the low-frequency input of which from the output of the second microcontroller 37 receives a binary sequence of pulses containing service information about measured and stored on this base station 1 during the previous mode "Information transfer to moving objects 2 power values of the received information radio signals. The second amplitude modulator 34 generates a high-frequency amplitude-modulated signal with a modulation factor of M 0.5. This signal is fed to the input of the second adjustable power amplifier 35, from the output of which the amplified signal is fed to the input of the second transmitting antenna 36. The second transmitting antenna 36 emits into the space the thus generated service radio signal containing information about the measured power values of the information radio signals received on this base station 1.

  5HH Thus, at each of the base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, stabilization of the operating frequency of the emitted information radio signals is carried out according to the operating frequency of one of the service radio signals received at this base station 1, at which this base station 1 carry out the emission of information radio signals at a given operating frequency. At each of these base stations 1, the indicated operating frequency of one of the received overhead radio signals is the operating frequency of the information radio signals emitted from the base station 1, which is the source of the transmitted information. By analogy with the above, the second transceivers 5, which are part of the base stations 1, which are not adjacent to the base station 1, which is the source of the transmitted information, operate in the “Adjustment of radiation power of base stations 1” mode. By analogy with the “Transferring information to moving objects 2” mode described above, in the “Adjusting the radiation power of base stations 1” mode, radios 6 located on moving objects 2 receive service radio signals emitted from base stations 1, in the zones 3 of which they are located. At the same time, in each radio receiver 6, the third microcontroller 46 blocks the display of service information on the indicator 47 based on the analysis of the received service radio signals. The mode “Adjustment of radiation power of base stations 1 has a fixed duration that is the same for all base stations 1. At the base station 1, which is the source of the transmitted information, and at all other base stations 1, after the end of the mode “Adjusting the radiation power of the base stations 1 L, the first microcontroller 18 and the second microcontroller 37, respectively, when transmitting other information radio signals to moving objects 2, again bring the first transceiver 4 and the second transceiver 5, respectively, in the mode "Information transfer to moving objects 2. Thus, the described technical solution allows, unlike the prototype, ive on the moving objects transmit information 2 located within the service area, without the use of switching and fiber-optic center, connecting the switching center to the base stations 1, which significantly simplifies the system. In addition, this technical solution allows to reduce, compared with the prototype, the number of preset reception frequencies of each of the radios 7 located on the moving objects 2, from seven to five, which also simplifies the system. Along with this, due to the rational placement of base stations 1 on the served territory, the system can significantly improve the quality of information reception on mobile objects 2 when changing the radii of zones 3 of the action of base stations 1, due to changes in the propagation conditions of radio waves.
