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 MV The 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, a hexagon, and with a transmission frequency set at each base station of this base station, which is one of seven different frequencies set different from the transmission frequencies of neighboring base stations, the reception frequencies of this base station are also set at each base station, 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 for 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. At the same time, radio communication between base stations without the use of additional radio channels is impossible, since for given h values of the radii of the base station coverage areas and parameters for placing base stations in the served territory, the distance between any two neighboring base stations is -u / 3 times greater than the radius of their zones of operation . 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 technical task to be solved is to simplify the system of transmitting information to mobile objects and to improve the quality of information reception on mobile objects based on the rational placement of base stations in the served territory.

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 shows 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 during the first cycle of information transfer to mobile objects, for the case in which the number of base stations is fifty-four, the number of mobile objects is five. In FIG. 2 shows a system for transmitting information to moving objects for the case in which the number of transceivers, one each of the base stations, is twelve, and the number of radios placed one on each of the moving objects is three, and the moving objects in FIG. . 2 are not shown. In FIG. 3 shows a transceiver included in each of the base stations, the base station of FIG. 3 is not shown. In FIG. 4 shows a radio placed on each of the moving objects, the moving object in FIG. 4 is not shown. In the present description, the following notation is used. 1 „- base station 1 with number“, where n 1,2, ..., TV ... positive integers 2t - movable object 2 with number t, where t 1,2, ..., M are positive integers; Zi - 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, ..., Q 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. . i covering the service area is located as shown in FIG. 1, base stations 1 (base stations li - 154), the radii of the 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 three base stations 1 are adjacent to each base station 1. By zone 3 of action of each base station 1 we mean the same zone 3 of action when radiating radio signals from this base station 1 and zone 3 actions when receiving radio signals at this base station 1. Moreover, by zone 3 actions when radiating radio signals from each base station 1 we mean a part of the territory within which, with undirected radiation from this base station stations 1 of power signals Pqmn at the operating frequency fq, the power of these radio signals when they are received at other base stations 1 and on moving objects 2 is not less than a certain threshold value characterizing the sensitivity of the reception channels of radio signals at base stations 1 and on moving objects 2. Under zone 3 of the action when receiving radio signals at each base station 1, we understand the part of the territory within which, with undirected radiation from other base stations 1, radio signals of the same power Pqmsi on the same At the 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 Rpr.min 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 for non-directional radiation from base stations 1 and non-directional reception of radio signals at base stations 1 and at moving 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. Edited by V.E. Dulevich. - M: Soviet Radio, 1978, p. 422) W, (1). “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 at the vertices of conditional cells, which are equal regular hexagons, densely covering 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 the points of placement of neighboring base stations 1. In Fig.1, the boundaries of the zones 3 of the action 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 by the formula (see, for example, A. M. Trakhtman. Introduction to the generalized spectral theory of signals. - M .: Soviet radio, 1972, p.14) P. (2) a ta The system uses two types of radio signals: information and service radio signals. If in the present description the type of radio signals V is not specified, then they can be both information and service radio signals. Six different operating frequencies (2 6) of the radio signals emitted from all base stations 1 are set. Of the six preset operating frequencies at each base station 1, are set, as shown in FIG. 1, the working frequency of the radio signals emitted from this base station 1 during one clock cycle of transmitting information to moving objects 2 (by the cycle of transmitting information to mobile objects 2 we mean the period of a single transmission of information to moving objects 2), different from the specified operating frequencies of the radio signals emitted from neighboring base stations 1 during the same cycle of transmitting information to moving objects 2. Thus, at base stations 1 that are not adjacent, the repeating operating frequencies of the radio signals are set, we radiate x with these base stations 1 within one cycle of information transfer on the mobile units 2. By the term "operating frequency mean value of the frequency of the carrier wave, central or any other characteristic of radio frequency bandwidth. Moreover, the frequency bands of the radio signals corresponding to different operating frequencies are non-overlapping. With the indicated placement parameters for base stations 1 on the served territory with the specified radius of action zones 3, at least two action zones of neighboring base stations 1 overlap at each point of the served territory 1. Since, when the information is transmitted once to mobile objects 2, the emission of information radio signals from neighboring base stations 1 carried out at different operating frequencies, at each receiving point receives information radio signals of at least two different specified operating frequencies. Therefore, to ensure guaranteed. receiving information radio signals on moving objects 2 when moving within the service area receiving information radio signals on each moving object 2 when transmitting information to moving objects 2 once, it is enough to carry out only at five different out of six given operating frequencies. Therefore, with multiple (fivefold) transmission of information to moving objects 2 with alternate use at each base station 1 of different five of the six specified operating frequencies of information radio signals emitted from this base station 1, different from the corresponding specified operating frequencies of information radio signals emitted from neighboring base stations 1, the reception of radio information signals at each moving object 2 is sufficient to carry out only at one of six specified operating frequencies. Thus, with multiple (fivefold) transmission of information to moving objects 2, the full cycle of information transmission includes five cycles of a single transmission of information, during each of which the radiation of information radio signals from each base station 1 is carried out at one of five specified from six specified operating frequencies, different from the other operating frequencies of the information radio signals emitted from this base station 1 set at this base station 1, and different from the corresponding specified operating frequencies of the information signals ionic radio signals emitted from neighboring base stations 1. Moreover, if / 9 (1) is one of the given different five operating frequencies of information radio signals emitted from one of the base stations 1 during the first cycle of information transfer to moving objects 2, then the other four the operating frequencies of the information radio signals emitted from this base station 1 during the second, third, fourth and fifth cycles w For transmitting information to moving objects 2, respectively, are set, for example, by the formula ,, „{/ $ -„ “+ v-isc , L No.-k, 9 + vi a () where / (v) is the working frequency of the information radio signals emitted from this base station 1 during the v cycle of information transfer to moving objects 2; v l, 2, ..., F are positive integers; V 5; q 1,2, ..., 2 are positive integers; Q 6. Information signals corresponding to the 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 there are mobile objects 2. C 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 radio information signals during the first cycle of information transfer to mobile objects 2 from the base station 1, which is the source of the transmitted information, to the base stations 1, in the action zones 3 of which there are mobile 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. At the same time, at all base stations 1, which are adjacent to the base station 1, which is the source of the transmitted information, they simultaneously receive information radio signals radiated from the last base station 1 and emit them at the corresponding given operating frequencies. Then, at all other base stations 1, which are adjacent to the indicated base stations 1, simultaneously receive information radio signals emitted from the indicated base stations 1 and their radiation at the corresponding given 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, they simultaneously receive the signals emitted from the previous base stations 1 information radio signals and their radiation at the corresponding given 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, the working ones are set - to the frequency of the information radio signals received at this base station 1 during each clock cycle of information transfer to moving objects 2, at which x with the base station 1 is carried out radiation of radio information at a given working frequency corresponding to this measure. On mobile objects 2, information radio signals emitted from base stations 1 are received during the first cycle of information transfer to mobile objects 2, in the zones 3 of which these mobile objects 2 are located. At the same time, information radio signals on mobile objects 2 are received at a given operating frequency , which at each moving object 2 is one of six specified operating frequencies. When transmitting information to moving objects 2 in the conditions of propagation of radio waves in free space, in order to ensure a given value of the radius R of the zone 3 of action of each base station 1 with known values of the operating frequency fq and sensitivity P n of the channels for receiving radio signals, it is necessary to provide the required value of power of radiated information 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 the information radio signals received from neighboring base stations 1 is measured during the first cycle of information transmission to mobile objects 2. Then, from each base station 1, service radio signals containing information about the measured power values are emitted. At each of these neighboring base stations 1 receive the specified service radio signals and adjust the power of the emitted information radio signals from the measured values of the power of information radio signals received at the base stations 1, which are adjacent

When temporarily separating the information and service radio channels at each base station 1 for the emitted service radio signals use the specified operating frequency of the radio signals. With respect to the indicated neighboring base station 1, and radiated from this base station 1. Adjusting the power of the radiated information radio signals at each of these neighboring base stations 1 is carried out, for example, according to the minimum power value from the measured power values of the 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, using the formula p, pRp.shshr P Rmin (4) ı1 ™ diesel p 1 1 / and meas.pr.min - из meas.

Formula (4) shows that at each base station 1, in the process of adjusting the power of the emitted information radio signals, it is necessary to set such a value of power PqV3 l at which equality is achieved m. Min. Min. Min.In this case, the power of the emitted information radio signals is adjusted n . MIN when the condition is met. „P. . w this radiation of information and service radio signals is carried out at various points in time. Then, 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 action zones 3 of which there are moving objects 2, and their reception at these moving objects 2 at given operating frequencies, as well as measuring the power of the information radio signals received from neighboring base stations 1, the emission from each base station 1 of service radio signals containing information about the measured power values, the reception of these service radio signals and the adjustment on each of said adjacent base stations 1 information radio power radiated from 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 is performed in this manner further four times. Moreover, each additional time, the emission of radio signals from each base station 1 is carried out at one of four additionally set of six specified operating frequencies, different from the other operating frequencies set at this base station 1 of the radio frequencies emitted from this base station 1, and different from the corresponding additional preset operating frequencies of radio signals emitted from neighboring base stations 1. To ensure the system is operational, the placement of base stations 1 near the boundaries of the served territory is necessary of exercise so that at each point in the service area overlapping occurred at least two zones 3 steps neighbor base stations 1. For example, the service area boundary shown in FIG. 1, it can be a closed polygonal line passing w through all extreme base stations 1 (base stations 1b Is, b, 1b, b b, lib Il6, hi, b, bb, bb, 143, U, b 154, bb, bb, 149, b2, Ug, 144, b9, b4, b3, 122, Il7, Il2, U, U). The system for transmitting information to moving objects 2 is shown in FIG. 2. The system comprises transceivers 4, one each of which is included in each of the base stations 1, and radio receivers 5, placed one at a time on each of the movable objects 2, located within the service area. In FIG. 2, as an example, a system is shown containing twelve transceivers 4 and three radio receivers 5. In this case, a description of the system and operation of this system is given for an arbitrary number of transceivers 4, one each of which is a base station 1, and radio receivers 5, placed one on one each of the movable objects 2 located within the serviced territory. Base stations 1 are located at the tops of 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 two 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 frequency of radio reception 5 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 systems for mobile radio communications. - M.: Eco-Trends, 2000, p.22.) Of the six specified different operating frequencies at each base station 1 in accordance with formula (3) five different transmission frequencies are set for this base station 1. Of the six specified operating frequencies for each moving object 2, one receiving frequency is set for a radio 5 located on this moving object 2. All elements and blocks that make up the system are known and described in literature. The transceiver 4 included in each base station 1 shown in FIG. 3, contains a first receiving antenna 6, three channels for receiving radio signals, each of which contains a first band-pass filter 7, a first low-noise amplifier 8, a first amplitude limiter 9, a first frequency detector 10, a first squaring unit 11, a first integrator 12, a first analog-digital converter (ADC) 13. The transceiver 4 also contains a first electronic switch 14, five controlled generators 15, an adjustable power amplifier 16, a transmitting antenna 17, a first microcontroller 18, a reference unit 19, and a second electronic mmutator 20. Yield first reception antenna 6, designed for omnidirectional reception information and service radio signals emitted from adjacent base stations 1, connected to the inputs of the first band-pass filter 7. Information and service signals are high-frequency electromagnetic waves corresponding chastotnomanipulirovannye same operating frequency. In this regard, at equal speeds of information transmission, the values of the bandwidth of information and service radio signals can be considered equal. The first band-pass filters 7 are used to select radio signals in frequency. Moreover, each of them is tuned to one of six specified operating frequencies, different from the tuning frequencies of the other first bandpass filters 7 included in this transceiver 4. The bandwidth of each first bandpass filter 7 is not less than the bandwidth of the radio signals of the corresponding operating frequency. The passbands of the first bandpass filters 7 are non-overlapping. In each channel for receiving radio signals, the output of the first band-pass filter 7 is connected to the input of the first low-noise amplifier 8, designed to amplify the received radio signals. The output of the first low-noise amplifier 8 is connected to the input of the first amplitude limiter 9, which serves to eliminate spurious amplitude modulation of signals arising from the propagation of radio waves. The output of the first amplitude limiter 9 is connected to the input of the first frequency detector 10, intended for the frequency detection of received radio signals. The output of the first low-noise amplifier 8 is also connected to the input of the first block And squaring, the output of which is connected to the input of the first integrator 12. Serially connected to the first block And squaring and the first integrator 12 are used to generate signals proportional to the power of the received radio signals. The output of the first integrator 12 is connected to the input of the first ADC 13. The outputs of all the first ADCs 13 are connected to the corresponding inputs of the first microcontroller 18. The first microcontroller 18 is designed to control the first electronic switch 14 and the second electronic switch 20, to form modulating binary pulse sequences corresponding to the service information transmitted to neighboring base stations 1 to adjust the power gain

adjustable power amplifier 16, as well as for forming in the transceiver 4 contained in the base station 1, which is the source of the transmitted information, modulating the binary sequence of pulses, the corresponding information transmitted to the moving objects 2. The outputs of all first frequency detectors 10 are connected to the switched inputs of the first electronic the switch 14, as well as to the corresponding inputs of the first microcontroller 18. The output of the first electronic switch 14 is connected to the control inputs are controlled x generators 15. In each transceiver 4, each of the controlled oscillators 15 is tuned in accordance with formula (3) to one of five preset transmission frequencies of this base station 1. Moreover, the tuning frequency of each of the controlled oscillators 15 is different from the tuning frequencies of other controlled generators 15 in the transceiver 4 contained in this base station 1, and the settings of the controlled oscillators 15 in the transceivers 4 contained in the neighboring base stations 1 are different from the corresponding frequencies S 15 are used to generate high-frequency frequency-controlled oscillations, the corresponding transmitted information and high-frequency frequency-manipulated signals, the corresponding service information transmitted to neighboring base stations 1. The outputs of the controlled generators 15 are connected to the corresponding switched inputs of the second electronic switch 20, intended for alternate connection on each base station 1 with multiple (fivefold) transmission of information to moving objects 2 outputs directs generators 15 to the input of the adjustable power amplifier 16, which is connected to the output of the transmitting antenna 17 are designed to non-directional radiation in space and service information signals. The inputs of the unit 19 of the job are connected to the inputs of the first microcontroller 18, which at the base station 1, which is the source of the transmitted information, serves to enter into the first microcontroller 18 information intended for transmission to moving objects 2, and at each of all other base stations 1 for setting the values of the operating frequencies of the information radio signals received at this base station 1 during each clock cycle of information transmission to mobile objects 2, at which information is emitted from this base station 1 radio signals at a given operating frequency corresponding to this measure. The outputs of the first microcontroller 18 are connected to one of the switched inputs of the first electronic switch 14, to the control inputs of the first electronic switch 14 and the second electronic switch 20, as well as to the control input of the adjustable power amplifier 16. All base stations 1 contain the same type of transceivers 4, differing only in operating frequencies, for which the controlled oscillators are tuned 15. The term “controlled generator is generally accepted. (See, for example, Theoretical Foundations of Radar. Edited by V.E. Dulevich. M: Soviet Radio, 1978, p. 358). The frequency of oscillations generated by the controlled generator is determined by the voltage acting on its control input. In this case, the controlled generator is a voltage controlled generator. Voltage controlled oscillators are known and described in the literature devices. (See, for example, Horowitz P., Hill. W. The art of circuitry. In 3 volumes: Vol. 1. Transl. From English. - 4th ed. Revised and enlarged M .: Mir, 1993, p. 308.) By the tuning frequency of a controlled generator we mean the center frequency of the operating range of the controlled generator corresponding to the operating range of control voltages. As the unit 19 of the task can be used any known and described in the literature digital data input device. (See, for example, B. Shevkoplyas Microprocessor structures. Engineering solutions. - M.: Radio and communications, 1993, p. 27.) A radio receiver 5, placed on each movable object 2, shown in FIG. 4, contains a second receiving antenna 21, one channel for receiving radio signals, which contains a second bandpass filter 22, a second low-noise amplifier 23, a second amplitude limiter 24, a second frequency detector 25, a second squaring unit 26, a second integrator 27, and a second ADC 28. The radio receiver 5 also contains a second microcontroller 29, an indicator 30. The output of the second receiving antenna 21, designed for omnidirectional reception of information radio signals emitted from base stations 1, is connected to the input of the second band-pass filter 22, tuned nnogo a predetermined receiving frequency of the radio receiver 5. The bandwidth of the second bandpass filter 22 is not less than the bandwidth information corresponding to the operating frequency of the radio. The output of the second band-pass filter 22 is connected to the input of the second low-noise amplifier 23, designed to amplify the received information radio signals. The output of the second low-noise amplifier 23 is connected to the input of the second amplitude limiter 24, which serves to eliminate spurious amplitude modulation of signals arising from the propagation of radio waves. The output of the second amplitude limiter 24 is connected to the input of the second frequency detector 25, designed for frequency detection

The output of the second low-noise amplifier 23 is also connected to the input of the second squaring unit 26, the output of which is connected to the input of the second integrator 27. The second squaring unit 26 and the second integrator 27 connected in series are used to generate signals proportional to the power of the received radio signals. The output of the second integrator 27 is connected to the input of the second ADC 28. The output of the second frequency detector 25 and the output of the second ADC 28 are connected to the input of the second microcontroller 29, designed to process the information received from base stations 1 and display it on the indicator 30, the inputs of which are connected to the outputs of the second microcontroller 29.

As the first amplitude limiters 9 and second amplitude limiters 24, for example, nonlinear resonant amplifiers tuned to the corresponding operating frequencies can be used. (See, for example, Gonorovsky IS Radio engineering circuits and signals. - M .: Radio and communications, 1986, p. 224.)

On all moving objects 2 are placed the same type of radio receivers 5, and the operating frequencies, which are tuned to the second band-pass filters 22, can coincide on different moving

objects 2.

At base stations 1 and on mobile objects 2, respectively, such values of the gain factors of the first low-noise amplifiers 8 and second low-noise amplifiers 23 are set, at which the sensitivity of the reception channels of informational radio signals at base stations 1 and on mobile objects 2 is equal to min- At base stations 1, depending on the set values of W, movable objects 2, such parameters of controlled generators 15 are set that provide the formation of signals with corresponding amplitudes, and such values of power gains of adjustable power amplifiers 16 at which the power of information radio signals emitted from these base stations 1, respectively, are equal to Pqwm during the entire cycle of information transfer to moving objects 2 (the values of the gain in power of the adjustable amplifiers 16 teley power set initially and during the operation of the system can be changed).  Moreover, the values of Pqmjl and the value of /. „„ N 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 the indicated 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.  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 12.13.13.14.15, 16 and 17 MHz respectively; 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 w of a single measurement of the power of the received radio signals is not more than OD ms.  Consider the operation of the system shown in FIG.  2.  At each base station 1, in addition to the base station 1, which is the source of the transmitted information, the operating frequencies of the information radio signals received at this base station 1 during each clock cycle of transmitting information to moving objects 2, at which base station 1 carry out the emission of information radio signals at a given operating frequency corresponding to this clock.  At the base station 1, which is the source of the transmitted information, information intended for transmission to the movable objects 2 is entered into the transceiver 4 setting unit 19.  During each clock cycle of transmitting information to moving objects 2, the system operates in two modes in turn: the mode "Information transfer to moving objects 2 (main mode) and the mode" Adjusting the radiation power of base stations 1 (service mode).  At each base station 1, the first microcontroller 18 sets the transceiver 4 in the mode of "Information transfer to moving objects 2 (first cycle).  At the base station 1, which is the source of the transmitted information, the first microcontroller 18 reads in binary code from the task unit 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 the movable objects 2, and a binary code attached to it containing an indication of the end of the radio information signal transmitted to the movable objects 2 during the first clock cycle.  The first microcontroller 18 generates a binary sequence of pulses corresponding to the resulting binary code, which is fed to one of the switched inputs of the first electronic switch 14.  At the same time, the first microcontroller 18 generates control signals at the control inputs of the first electronic switch 14, through which the first electronic switch 14 connects the specified switched input to the control input of one of the controlled generators 15, tuned to the first of the five different transmission frequencies of this base station 1.  This controlled generator 15 by the signals acting at the output of the first electronic switch 14, generates a high-frequency frequency-manipulated signal, which is fed to the corresponding switched input of the second electronic switch 20.  The second electronic switch 20 according to the control signals of the first microcontroller 18 generates at the input of the adjustable power amplifier 16 a high-frequency frequency-controlled signal acting at the output of the specified controlled generator 15.  The transmitting antenna 17 emits into the space the informational radio signal thus formed, corresponding to the information transmitted to the moving objects 2 during the first clock cycle.  The radiated informational radio signal ends with a sequence of radio pulses containing a sign of the end of the informational radio signal transmitted to the moving objects 2 during the first cycle.  The reception of the information radio signal emitted during the first cycle of information transmission from the base station 1, which is the source of the transmitted information, is carried out at neighboring base stations 1 using the transceivers 4 contained in them.  In this case, the first receiving antenna 6, which is part of each of these transceivers 4, receives an information radio signal emitted from the base station 1, which is the source of the transmitted information.  The received information radio signal is fed to the inputs of the first band-pass filters 7.  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 first band-pass filters 7, tuned to the first of five different out of six preset operating frequencies of the information radio signals emitted by base station 1, which is the source of the transmitted information, the corresponding high-frequency frequency-manipulated signal corresponding to the received information radio signal acts.  This signal is fed to the input of the first low-noise amplifier 8, from the output of which the signal is fed to the input of the first amplitude limiter 9.  The first amplitude limiter 9 carries out the amplitude limitation of the signal.  From the output of the first amplitude limiter 9, the signal is fed to the input of the first frequency detector 10.  The first frequency detector 10 carries out frequency detection of the received information radio signal and generates a binary sequence of pulses corresponding to the transmitted information, which are received at the corresponding switched input of the first electronic switch 14 and at the input of the first microcontroller 18.  At the same time, the signal from the output of the indicated first low-noise amplifier 8 is fed to the input of the first squaring unit 11, the output signal of which is fed to the input of the first integrator 12, which, at the input of the first ADC 13, generates a signal proportional to the power of the received information radio signal in accordance with formula (2) .  A digital code from the outputs of the specified i of the first ADC 13 is supplied to the inputs of the first microcontroller 18.  The first microcontroller 18 determines by the digital code acting on the output of the specified first ADC 13 and the known value of the gain of the corresponding channel for receiving radio signals, the power value of the received information radio signal R.  The first microcontroller 18 checks the p conditions of the Rdr prmin, where K.   1. 2, and if it is executed, it makes a decision on the presence of an informational radio signal of the corresponding operating frequency at the input of the transceiver 4, otherwise the first microcontroller 18 makes the opposite decision.  (Coefficient K 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 are worsened and insufficient for receiving radio signals from remote base stations 1. ) Then, the first microcontroller 18 reads from the set unit 19 the set values of the operating frequencies of the information radio signals received at this base station 1 during the first clock cycle of transmitting information to moving objects 2, at which the information radio signals are emitted from this base station 1 at a given operating frequency, corresponding to this clock, and determines from these given values of the operating frequencies and the values of the signals acting on the outputs of the corresponding first ADC 13, the 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 first of five different out of six specified operating frequencies of the information radio signals emitted from base station 1, being a source of transmitted information. ) The first microcontroller 18 generates control signals at the control inputs of the first electronic switch 14, through which the first electronic switch 14 connects the output of the first frequency detector 10, corresponding to the operating frequency of the information radio signal of maximum power, to the control input of the controlled generator 15, tuned to the first of five different preset transmission frequencies of this base station 1.  The controlled generator 15 generates a high-frequency frequency-manipulated signal of the specified operating frequency, which is fed to the corresponding switched input of the second electronic switch 20.  The second electronic switch 20 according to the signals of the first microcontroller 18, acting on its control inputs, connects the output of the specified controlled generator 15 to the input of an adjustable power amplifier 16.  From the output of the adjustable power amplifier 16, a power-amplified signal is fed to the input of a transmitting antenna 17, which emits into the space an information radio signal corresponding to information transmitted to moving objects 2 during the first clock cycle.  The radiated informational radio signal also ends with a sequence of radio pulses containing a sign of the end of the informational radio signal transmitted to the moving objects 2 during the first clock cycle.  The reception of information radio signals emitted during the first clock cycle of information transmission from the indicated neighboring base stations 1, is carried out at the base stations 1, which are adjacent to the indicated neighboring base stations 1, using the transceivers 4 contained therein.  Moreover, the first receiving antenna 6, which is part of each of these transceivers 4, W receives information radio signals emitted from these base stations 1.  Received information radio signals are fed to the inputs of the first bandpass filters 7, which select them in frequency.  At each base station 1, which is adjacent to the indicated neighboring base stations 1, at the output of the first bandpass filters 7, high-frequency frequency-manipulated signals corresponding to the received information radio signals act.  These signals are fed to the inputs of the first low-noise amplifiers 8, from the outputs of which the signals are fed to the inputs of the first amplitude limiters 9.  The first amplitude limiters 9 carry out the amplitude limitation of the signals.  From the outputs of the first amplitude limiters 9, the signals are fed to the inputs of the first frequency detectors 10.  The first frequency detectors 10 carry out frequency detection of the received information radio signals and generate binary sequences of pulses corresponding to the transmitted information, which are fed to the switched inputs of the first electronic switch 14 and to the inputs of the first microcontroller 18.  At the same time, the signals from the outputs of the first low-noise amplifiers 8 are fed to the inputs of the first squaring unit 11, the output signals of which are fed to the inputs of the first integrators 12, which, at the inputs of the first ADCs 13, generate signals proportional to the power of the received information radio signals in accordance with formula (2).  Digital codes from the outputs of the first ADCs 13 are supplied to the inputs of the first microcontroller 18.  The first microcontroller 18 determines by the digital codes acting on the outputs of the first ADCs 13, and the known values of the gain factors of the respective channels for receiving radio signals, the power values P of the received information radio signals.  For each of the channels for receiving radio signals, the first microcontroller 18 checks the condition Pjjp prmin, where K3fm 1. 2, and if it is executed, it makes a decision on the presence of an informational radio signal of the corresponding operating frequency at the input of the transceiver 4, otherwise the first microcontroller 18 makes the opposite decision.  Then, the first microcontroller 18 reads from the setting unit 19 the set values of the operating frequencies of the information radio signals received at this base station 1 during the first clock cycle of transmitting information to moving objects 2, at which the information radio signals are emitted from this base station 1 at a given operating frequency corresponding to this clock, and determines from these preset values of the operating frequencies and the values of the signals acting on the outputs of the corresponding first ADCs 13, the operating frequency of the information diosignala maximum power.  The first microcontroller 18 generates control signals at the control inputs of the first electronic switch 14, through which the first electronic switch 14 connects the output of the first frequency detector 10, corresponding to the operating frequency of the information radio signal of maximum power, to the control input of the controlled generator 15, tuned to the first of various five preset frequencies transmitting this base station 1.  The controlled generator 15 generates a high-frequency frequency-manipulated signal of the specified operating frequency, which is fed to the corresponding switched input of the second electronic switch 20.  The second electronic switch 20 according to the signals of the first microcontroller 18, acting on its control inputs, connects the output of the specified controlled generator 15 to the input of an adjustable power amplifier 16.  From the output of the adjustable power amplifier 16, a power-amplified signal is fed to the input of a transmitting antenna 17, which emits into the space an information radio signal corresponding to information transmitted to moving objects 2 during the first clock cycle.  The radiated informational radio signal also ends with a sequence of radio pulses containing a sign of the end of the informational radio signal transmitted to the moving objects 2 during the first clock cycle.  By analogy with the above, during the first cycle of transmitting information to moving objects 2, transceivers 4, which are part of all other base stations 1, function.  At each base station 1, the first microcontroller 18 also reads the signals from the outputs of all the first ADCs 13 and remembers from them the power of the information radio signals received at these base stations 1 in the "Information transfer to moving objects 2 (first cycle) mode.  The number of these base stations 1 includes the base station 1, which is the source of the transmitted information, since at this base station 1 the radio information signals emitted from neighboring base stations 1 are also received and their power is measured.  The mode "Adjusting the radiation power of base stations 1 (first cycle).  Upon completion of the formation of a binary sequence of pulses corresponding to the information transmitted to the moving objects 2 during the first cycle of transmitting information to the moving objects 2, at the base station 1, which is the source of the transmitted information, the first microcontroller 18 sets the transceiver 4 into the “Adjustment of radiation power of base stations” mode 1 (first measure).  In this case, the first microcontroller 18 generates on one of the w switched inputs of the first electronic switch 14 a binary sequence of pulses containing service information about the measured and stored in the mode of “Information Transmission to Moving Objects 2 (first cycle) power values of the received information radio signals at base station 1, which is a source of transmitted information during the first cycle of information transfer to mobile objects 2.  At the same time, the first microcontroller 18 generates control signals at the control inputs of the first electronic switch 14, through which the first electronic switch 14 connects the specified switched input to the control input of one of the controlled generators 15, tuned to the first of the five different transmission frequencies of this base station 1.  This controlled generator 15 by the signals acting at the output of the first electronic switch 14, generates a high-frequency frequency-manipulated signal, which is fed to the corresponding switched input of the second electronic switch 20.  The second electronic switch 20 according to the control signals of the first microcontroller 18 generates at the input of the adjustable power amplifier 16 a high-frequency frequency-controlled signal acting at the output of the specified controlled generator 15.  The transmitting antenna 17 emits into the space the thus generated service radio signal containing service information about the power values of the received information radio signals measured at the base station 1, which is the source of the transmitted information, measured during the first cycle of transmitting information to moving objects 2.  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 information radio signal emitted from the base station 1, which is the source of the transmitted information, during the first cycle of information transfer to moving objects 2, the first microcontroller 18 leads (as a result of identification by the first microcontroller 18 of a sequence of radio pulses containing a sign of the end of the information radio signal transmitted on the move important objects 2 during the first cycle) transceiver 4 into the mode "Adjusting the radiation power of base stations 1 (first cycle).  In this case, the first microcontroller 18 generates control signals at the control inputs of the first electronic switch 14, by which the first electronic switch 14 disconnects the outputs of the first frequency detectors 10 from the inputs of the controlled generators 15.  To the input of the latter, the first electronic switch 14 connects one of the outputs of the first microcontroller 18, which generates a binary sequence of pulses on it containing service information about the measured and stored in the mode of “Information Transmission to Moving Objects 2 (first cycle) power values of the received information radio signals during the first cycle of information transfer to moving objects 2.  At the same time, the first microcontroller 18 generates control signals at the control inputs of the first electronic switch 14, through which the first electronic switch 14 connects the specified switched input to the control input of one of the controlled generators 15, tuned to the first of the various five preset transmit frequencies of this base station 1.  This controlled generator 15 by the signals acting at the output of the first electronic switch 14, generates a high-frequency frequency-manipulated signal, which is fed to the corresponding switched input of the second electronic switch 20.  The second electronic switch 20 according to the w W control signals of the first microcontroller 18 generates at the input of the adjustable power amplifier 16 a high-frequency frequency-controlled signal acting at the output of the specified controlled generator 15.  The transmitting antenna 17 emits into the space the service radio signal thus formed, containing service information about the power values of the received information radio signals measured at the first neighboring base stations 1, measured during the first cycle of transmitting information to moving objects 2.  At the same time, at each of these neighboring base stations 1, the first receiving antenna 6 receives overhead radio signals emitted from base stations 1 that are adjacent to said neighboring base stations 1.  Received service radio signals are fed to the inputs of the first band-pass filters 7, which select them in frequency.  The signals from the outputs of the first band-pass filters 7 are fed to the inputs of the first low-noise amplifiers 8.  From the outputs of the first low-noise amplifiers 8, the signals are fed to the inputs of the first amplitude limiters 9, which implement the amplitude limitation of the signals.  From the outputs of the first amplitude limiters 9, the signals are fed to the inputs of the first frequency detectors 10, which carry out frequency detection of the received service radio signals and generate binary pulse sequences containing information about the measured power values of the information radio signals received at base stations 1, which are adjacent to the indicated neighboring base stations 1 (among base stations 1 that are adjacent to said neighboring base stations 1, have tsya and the base station 1, which is a source of information to be transmitted).  Specified binary

sequences of pulses are fed to the inputs of the first microcontroller 18. Similarly to the above, the first microcontroller 18 makes a decision about the presence or absence at the input of the transceiver 4 of the service radio signals of the corresponding operating frequencies by comparing the values of their power with the threshold

radiated information radio signals and generates a control signal at the control input of the adjustable power amplifier 16, in accordance with which the power of the radiated information radio signals takes the value Pqmn.

By analogy with the above, the transceivers 4 that 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 “Adjusting the radiation power of base stations 1 (first cycle) mode. of base stations 1, the first microcontroller 18 compares the measured values of the power of information radio signals received at base stations 1, which are adjacent to the indicated neighboring base station 1, and radiated from this base station 1 (from base station 1, containing transceiver 4, the composition of which includes the specified first microcontroller 18), and determines among them the minimum value of the power Ryum „. (The registration of informational radio signals occurs when the condition P is met, where zap 1–2, therefore, the value of the hall R „is min-TT and is non-zero.) Then the first microcontroller 18 The“ Adjustment of radiation power of base stations 1 (first cycle) mode has a fixed and the same duration at all base stations 1. At each base station 1, at the end of the "Adjustment of the radiation power of base stations 1 (first cycle) mode, the first microcontroller 18 sets the transceiver 4 to the" Information transfer to moving objects 2 (second cycle) mode. By analogy with the above, two transceivers 4, which are part of each base station 1, operate during the second and all subsequent clocks of information transfer to moving objects. At each of the base stations 1 that are not sources of transmitted information, at the end of the mode stations 1 (fifth clock cycle), the first microcontroller 18, when transmitting other informational radio signals to moving objects 2, returns the transceiver 4 to the mode “Information transfer to moving objects 2 (ne vy cycle). Information radio signals emitted from each base station 1 during each clock cycle of information transmission to moving objects 2 penetrate through the first receiving antennas 6 to the inputs of transceivers 4 included in neighboring base stations 1. However, this does not cause a “looping of the system, since the radiation 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 at this base station 1 information radio signals one The second of the operating frequencies set at this base station is 1. 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, it can be assumed that the transceivers 4 included in the base stations 1 simultaneously receive radiated from neighboring base stations 1 information radio signals and their radiation at the corresponding given operating frequencies. At each movable object 2 located within the service area, the second receiving antenna 21, which is part of the radio receiver 5 located on it, shown in FIG. 4, receives during the first cycle of information transmission to mobile objects 2 information radio signals emitted from base stations 1, in the action zones 3 of which this mobile object 2 is located. These signals from the output of the second receiving antenna 21 are fed to the input of the second band-pass filter 22 their selection in frequency. If the working frequency of one of the information radio signals received during this cycle of information transfer to moving objects 2 coincides with the tuning frequency of the second band-pass filter 22, then the second band-pass filter 22 passes the received signal to the output. The signal from the output of the second band-pass filter 22 is fed to the input of the second low-noise amplifier 23, the signal from the output of which is fed to the input of the second amplitude limiter 24. The second amplitude limiter 24 carries out the amplitude limitation of the signal. From the output of the second amplitude limiter 24, the signal is fed to the input of a second frequency detector 25, which frequency-senses the received informational radio signal. The binary sequence of pulses produced by the second frequency detector 25 is fed to the input of the second microcontroller 29. At the same time, the signal from the output of the second low-noise amplifier 23 is fed to the input of the second squaring unit 26, the output of which is fed to the input of the second integrator 27, which is at the input of the second The ADC 28 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 second ADC 28 is fed to the input of the second microcontroller 29. The second microcontroller 29 determines by the digital code acting on the outputs of the second ADC 28 and the known value of the gain of the channel for receiving radio signals, the power value P of the received information radio signal. The second microcontroller 29 checks the condition Ppr Pjjp min and, if it is satisfied, makes a decision on the presence of an information radio signal of the corresponding operating frequency at the input of the radio receiver 5, otherwise the second microcontroller 29 takes the opposite decision. (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 second microcontroller 29 follows the binary pulse sequence acting on the output of the second the frequency detector 25, generates signals at the inputs of the indicator 30, by which the indicator 30 displays information transmitted to the mobile 2 objects during the first measure. If the operating frequency of any of the information radio signals received during this cycle of information transfer to moving objects 2 does not coincide with the tuning frequency of the second band-pass filter 22, then there is no signal at the output of the second band-pass filter 22. The second microcontroller 29 generates at the output signals that turn off the indicator 30. During the second and all subsequent clock cycles of transmitting information to moving objects 2, the radio receivers 5 located on them operate in a similar way. Moreover, due to the multiple (fivefold) transmission of information to moving objects 2 with the alternate use of different five specified operating frequencies of the emitted information radio signals, radios 5 located on moving objects 2 located within the service area, at least during one cycle of information transfer to moving objects 2 receive information radio signals at a given operating frequency. When repeatedly receiving informational radio signals on moving objects 2, the second microcontrollers 29, which are part of the radios 5 located on them, block the re-display of the received information on the indicator 30. Similarly to the above radios 5, placed on moving objects 2, they also receive service radio signals emitted from base stations 1, in zones 3 of which they are located. At the same time, in each radio receiver 5, the second microcontroller 29 blocks the display of service information on the indicator 30 according to the analysis of received service radio signals. Thus, the transceivers 4 included in the base stations 1, in accordance with the information contained in the job blocks 19, sequentially, according to all directions from 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 the information signals radiated from the previous base stations 1 and their radiation at the corresponding predetermined operating frequencies. At the same time, W transmit information from the base station 1, which is the source of the transmitted information, to the base stations 1, in the action zones 3 of which there are mobile objects 2, and their reception at these mobile objects 2, as well as the measurement of the power of information radio signals received from neighboring base stations 1, the emission from each base station 1 of service radio signals containing information about the measured power values, the reception of these service radio signals and the adjustment at each of these neighboring base stations 1 power of the emitted information radio signals according to the measured power values of the 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, at the given operating frequencies, only five times are performed in this manner, and each time the radiation of radio signals from each base station 1 is carried out at one of five specified from six specified operating frequencies, different from other operating frequencies set at this base station 1 radio signals emitted from this base station 1, and different from the corresponding additionally specified operating frequencies of radio signals emitted from neighboring base stations 1. Thus, the described technical solution allows, in contrast to the prototype, to transmit information to moving objects 2 within served territory, without the use of a switching center and fiber-optic communication lines connecting the switching center with base stations 1, which greatly simplifies the system. In addition, this technical solution allows to reduce, compared with the prototype, the number of predetermined reception frequencies of each of the radios 6 located on moving objects 2, from seven to one, which also simplifies the system. Along with this thanks

the rational placement of base stations 1 on the served territory, the system can significantly improve the quality of information reception on moving 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.
