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 Fundamentals of cellular communications. Edited by DB Zimin. - M .: Radio and communications, 2000, p.20-68), containing the first transceivers included one in 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

a hexagon, and with the transmission frequency of this base station specified at each base station, which is one of seven different frequencies, different from the transmission frequencies of neighboring base stations, the reception frequencies of this base station are also set at each base station, the second transceivers placed one at a time on each of the moving objects located within the coverage areas of all base stations, with predetermined transmission frequencies and reception frequencies of each second transceiver, and the specified reception frequencies of the bases stations coincide with the preset transmission frequencies of each second transceiver, which are different from any of the preset transmission frequencies of the base stations, the preset reception frequencies of each second transceiver are all seven preset transmission frequencies of the base stations, the switching center, fiber-optic communication lines connecting the switching center to the 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

the values of the radii of the coverage areas of base stations and the parameters of the placement of base stations in the served territory distance

between any two neighboring base stations, l / 3 times the radius of the zones of their action.

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. Under the terms "neighboring base station or" base station that is adjacent to this base station

we understand the 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 transmitting information to mobile objects, 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 mobile objects for the case in which the number of transceivers, one each of the base stations, is nineteen, and the number of radio receivers placed one on each of the mobile objects is three, and the mobile 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 l, where n, 2, ..., N are positive integers; 2 „, - movable object 2 with number m, where m 1,2, ..., M are positive integers; 3 „- zone 3 of the action of the base station 1„; / - operating frequency of the radio signals emitted from the base

station 1, where q, 2, ..., Q are positive integers. In those cases

when this does not lead to misinterpretation, the indices in the above notation are omitted.

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 li - 119 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.

By zone 3 of action of each base station 1 we mean equal to each other zone 3 of action when radiating radio signals from this base station 1 and zone 3 of action when receiving radio signals of this base station 1.

Moreover, by zone 3 of action 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 1, of radio signals of power Pqiasi at the operating frequency fq, the power of these

radio signals during their non-directional reception at other base stations 1 and at moving objects 2, not less than a certain threshold value RPR.MIN, characterizing the sensitivity of the reception channels

of radio signals at base stations 1 and at moving objects 2. Under 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 of radio signals of the same power Pqmn at the same operating frequency fq, power of these radio signals when

undirected reception at this base station 1, not less than the same value of P ..

In this regard, assuming that the propagation of radio waves occurs in free space, and the served area is a plane, the zone 3 of action of each base station 1 with non-directional radiation from base stations 1 and non-directional reception of radio signals at base stations 1 and mobile objects 2 is a circle with a center at the location of this base station 1 and a radius determined by the formula (see, for example, Theoretical Foundations of Radar. Edited by V.E. Dulevich. - M.: Soviet Radio, 1978, p.402 )

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 points of placement of neighboring base stations 1. In Fig. 1, the boundaries of the zones 3 of action of base stations 1 are shown conditionally by circles.

In the present description, by the term "signal power, we mean the average power P of the signal s (t), determined in the time interval

ta t tb according to the formula (see, for example, A.M. Trakhtman. Introduction to

generalized spectral theory of signals. - M .: Soviet Radio, 1972, p.14)

The system uses two types of radio signals: 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 seven different operating frequencies (O 7) of radio signals,

emitted from all base stations 1. Of the seven predetermined operating frequencies at each base station 1 is 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 moving objects 2.

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.

With the indicated placement parameters for the base stations 1 on the serviced territory with the specified radius of action zones 3, at least three action zones of neighboring base stations 1 overlap at each point of the serviced territory. 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 point of reception

informational radio signals of at least three different specified operating frequencies are received. Therefore, to ensure the guaranteed reception of informational radio signals on moving objects 2 when they move within the service area, receiving informational radio signals on each moving object 2 with a single transmission of information to moving objects 2 is sufficient to carry out only five different out of seven specified 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 seven specified operating frequencies of the information radio signals emitted from this base station 1, different from the corresponding specified operating frequencies of the information radio signals emitted from neighboring base stations 1, the reception of information radio signals at each moving object 2 is sufficient to carry out only at one of seven 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 seven specified operating frequencies, different from the other operating frequencies specified at this base station 1 of the information radio signals emitted from this base station 1, and information different from the corresponding specified operating frequencies radio signals emitted from neighboring

base stations 1. Moreover, if / g (I) is one of the given

different five operating frequencies of the 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 working

the frequencies of the information radio signals emitted from this base station 1 during the second, third, fourth and fifth cycles of transmitting information to moving objects 2, respectively, are set, for example, by the formula

where / 9 (v) is the working frequency of the information radio signals emitted from

this base station 1 during v cycle information transmission to mobile objects 2; v l, 2, ..., V are positive integers; V 5; q 1,2, ..., Q are positive integers; Q 1.

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 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. Moreover, at all base stations 1,

1L (11s, (3)

being adjacent to the base station 1, which is the source of the transmitted information, simultaneously receive the information radio signals emitted from the last base station 1 and emit them at the corresponding predetermined 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, set 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 of the base station 1 is carried out radiation information radio signals at a predetermined operating frequency corresponding to this measure.

On moving objects 2 receive information radio signals emitted from base stations 1 during the first cycle

transmitting information to mobile objects 2, in the zones of action 3 of which these mobile objects 2 are located. In this case, the reception of information radio signals on mobile objects 2 is carried out at a given operating frequency, which at each mobile object 2 is one of seven specified operating frequencies.

When transmitting information to moving objects 2 in the conditions of propagation of radio waves in free space to provide a given value of the radius R of the zone 3 of the action of each base station 1 with known values of the operating frequency fq and sensitivity P

of the channels for receiving radio signals, it is necessary in accordance with formula (1) to provide the required value of the RF RF power 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 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 according to the measured values of the power of information radio signals,

received at base stations 1, which are adjacent to the specified neighboring base station 1, and radiated from this base station 1.

The power control of the radiated information radio signals at each of these neighboring base stations 1 is carried out, for example, by 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 specified neighboring base station 1, and radiated from this base station 1 using the formula

where izprmin is the minimum power value from the corresponding measured power values of the information radio signals; Rdizl is the power value of the emitted information radio signals, which is set at the base station 1 in the process of adjustment according to the measurement results; AGMP 1 - coefficient determining the margin for

sensitivity and power adjustment range of radiated information radio signals.

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 power value Pqwsl at which

the equality of ism pr min min min is fulfilled. At the same time, the power of the radiated information radio signals is adjusted

when the condition RTm - ±.

radio signals use the specified operating frequencies of the radio signals. In this case, the 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 specified from seven preset operating frequencies, different from the other operating frequencies set forth 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 operability of the system, the placement of base stations 1 near the boundaries of the served territory must be implemented 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. So, for example, the border of the served territory,

shown in FIG. 1, can be a closed polygonal line passing through all the extreme base stations 1 (base stations b0, b4, hi, hs, hi,

Bb, b0, b3, 140 146, 152, Is, 1b2, 1b6,, b3, 1b9, 1b8, b1b7, 1b3, bs, b3, U, Ul, bb, bb h b3) Information system for 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 nineteen 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 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 3 of action of neighboring base stations 1 overlap.

The transmission frequency of the base station 1 is the corresponding operating frequency of the radio signals emitted from this base station 1. The receiving frequency of the radio 5 is the corresponding operating frequency of the information radio signals received at the corresponding moving object 2.

The terms “transmission frequency and” reception frequency of a 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 seven specified different operating frequencies at each base station 1, in accordance with formula (3), five different transmission frequencies of this base station 1 are specified. Of the seven specified operating frequencies at each moving object 2, one receiving frequency of the radio 5 located on this mobile object 2.

All elements and blocks that make up the system are known and described in the literature.

The transceiver 4 included in each base station 1 shown in FIG. 3, contains a first receiving antenna 6, seven channels for receiving radio signals, each of which contains a first bandpass 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 task unit 19, a second electronic switch 20.

The output of the first receiving antenna 6, designed for non-directional reception of information and service radio signals emitted from neighboring base stations 1, is connected to the inputs of all the first bandpass filters 7. Information and service radio signals are high-frequency frequency-manipulated electromagnetic oscillations of the corresponding identical operating frequencies. In this regard, at equal speeds

information transfer 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 seven preset 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 squaring block 11, the output of which is connected to the input of the first integrator 12. The first squaring block 11 and the first integrator 12 are connected in series 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 service information transmitted to neighboring base stations 1, for adjusting the power gain of the adjustable power amplifier 16, as well as for generating in the transceiver 4 contained in the base station 1, which is the source of the transmitted information modulating a binary pulse sequence, the corresponding information transmitted to moving objects 2. The outputs of all the first frequency detectors 10 are connected to the switched inputs of the first electronic 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 of the controlled oscillators 15. In each transceiver 4, each of the controlled oscillators 15 is configured in accordance with formula (3) to one of the five preset transmission frequencies of this base station 1. At the same time 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 different from the corresponding tuning frequencies of the controlled oscillators 15 in the transceivers 4 contained in the neighboring base stations 1. The controlled generators 15 are used to generate high-frequency frequency-controlled oscillations corresponding to the transmitted information and high-frequency frequency-manipulated signals corresponding to the service information transmitted to the neighboring base stations 1. Outputs of the controlled generators 15 are connected to the corresponding switched inputs of the second electronic switch 20, designed to the next connection at each base station 1 with multiple (fivefold) transmission of information to moving objects 2 outputs of controlled generators 15 to the input of an adjustable power amplifier 16, the output of which

a transmitting antenna 17 is connected, intended for non-directional radiation into the space of information and service radio 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, which are controlled by controlled generators 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 Circuit Engineering. In 3 volumes: Vol. 1. Transl. From English. - 4th ed. Revised and enlarged M .: Mir, 1993, p. 308.) Under the tuning frequency of the controlled generator

we understand the central 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, Shevkoplyas B. V. Microprocessor structures. Engineering solutions. - M.: Radio and communications, 1993, p. 27.)

A radio 5 located 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 band-pass 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 5 also contains a second microcontroller 29, an indicator 30.

The output of the second receiving antenna 21, designed for the omnidirectional reception of information radio signals emitted from base stations 1, is connected to the input of the second band-pass filter 22, tuned to a given frequency of reception of this radio receiver 5. The bandwidth of the second band-pass filter 22 is not less than the bandwidth of the information radio signals corresponding operating frequency. 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,

intended for the implementation of frequency detection of received information radio signals. 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, IS Gonorovsky. Radio engineering circuits and signals. - M.: Radio and communications, 1986, p. 224.)

On all moving objects 2 are placed the same type of radio 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 at mobile objects 2 is equal to - At base stations 1, depending from setpoints

base stations 1 during each cycle of information transfer to moving 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 for which the power of information radio signals emitted from these base stations 1, respectively equal Pqwm during the entire cycle of information transfer

on moving objects 2 (the values of the power amplification factors of the adjustable power amplifiers 16 are set initially and can be changed during the operation of the system). In this case, the values

and the value is selected based on the set value of the radius of the zone 3

the actions of each base station 1, equal to the side length 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.

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 the modulating binary sequences of pulses corresponding to the information transmitted to the moving objects 2, as well as service information,

not less than 10 ms, the time interval 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 mobile objects 2. Then, the first microcontroller 18 generates a resulting binary code containing a binary code corresponding to information transmitted to mobile objects 2, and the binary code attached to it containing the terminator

information radio signal transmitted to the movable objects 2 during the first 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 on 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 oscillators 15, tuned to the first of various five preset frequencies p broadcasts of this base station 1. This controlled generator 15 generates a high-frequency frequency-manipulated signal from the signals output from the first electronic switch 14, which is fed to the corresponding switched input of the second electronic switch 20. The second electronic switch 20 forms the control signals of the first microcontroller 18 at the input of an adjustable power amplifier 16, a high-frequency frequency-manipulated signal acting at the output of the specified controlled generator 15. P Reda antenna 17 radiates into the space thus formed information signal is corresponding to information carried on moving objects 2 in the first 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 clock 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 contained in them

4. 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 bandpass 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 bandpass filters 7, tuned to the first of five different out of seven preset operating frequencies of the information radio signals emitted by the base station 1, which is the source of the transmitted information, operates corresponding to the received information radio signal chastotnomanipulirovanny signal. 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) . Digital code from the outputs of the specified

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 P.

the decision on the presence at the input of the transceiver 4 of the information radio signal of the corresponding operating frequency, otherwise the first microcontroller 18 makes the opposite decision. (The coefficient KZt -12 provides a margin of sensitivity,

necessary to measure the power of the received information radio signals when the propagation conditions of the radio waves deteriorate and insufficient to receive the radio signals from the 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 transmitting information to moving objects 2, in which from this base station 1 they carry out the emission of information radio signals at a given working hour Tote corresponding to this clock cycle, and determines to these given values of operating frequencies and values of the signals acting on respective outputs of the first ADC 13, the operating frequency of the radio maximum power information. (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 seven specified operating information frequencies

radio signals emitted from the base station 1, which is the source of the 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 maximum information power radio signal, to the control input of a controlled generator 15, tuned to the first of various five preset transmission frequencies of this base station 1. the herator 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 the adjustable amplifier 16 power. 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 cycle of information transmission from these neighboring base stations 1, is carried out at base stations 1, which are adjacent to these neighboring base stations 1, using the transceivers 4 contained therein. Moreover, the first receiving antenna 6, part of each of these transceivers 4,

receives informational radio signals emitted from these base stations 1. Received informational radio signals are fed to the inputs of the first band-pass 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 the frequency detection of the received information radio signals and generate binary sequences of pulses,

corresponding to the transmitted information that are received at the switched inputs of the first electronic switch 14 and 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 of the corresponding channels for receiving radio signals, the power values P received

conditions PPR -, where Kzap 1.2, and in case of its implementation accepts

the decision on the presence at the input of the transceiver 4 of the information radio signal of the corresponding operating frequency, 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 the transmission of this base station 1. The controlled generator 15 generates a high-frequency frequency-manipulated signal of the specified operating part you, which is supplied to the corresponding switching input of the second electronic switch 20. The second electronic switch 20 and microcontroller 18 signals the first acting on its control inputs, connects the output of said controlled oscillator 15 to the input

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 forms on one of

the switched inputs of the first electronic switch 14 is a binary sequence of pulses containing service information about measured and stored in the mode “Information transmission to moving objects 2 (first cycle) power values of received information radio signals at base station 1, which is a source of transmitted information during the first information transmission cycle to moving objects 2. At the same time, the first microcontroller 18 forms control inputs at the control inputs of the first electronic switch 14 signals 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 various five preset transmission frequencies of this base station 1. This controlled generator 15 according to the signals acting at the output of the first electronic switch 14, produces 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 The first microcontroller 18 generates a high-frequency frequency-modulated signal at the input of the adjustable power amplifier 16, which acts on the output of the specified controlled oscillator 15. The transmitting antenna 17 emits into the space a service radio signal generated in this way, containing service information about information transmitted to moving objects measured during the first clock cycle 2 power values of the received information radio signals at base station 1, which is the source of the transmitted and formation.

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 the moving objects 2, the first microcontroller 18 leads (as a result of the identification by the first microcontroller 18 of a sequence of radio pulses containing the sign of the end of the information radio signal transmitted to the moving objects 2 during the first clock) transceiver 4 to the mode "Adjustment of the radiation power of base stations 1 (the first clock). 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 last, the first electronic switch 14 connects one of the outputs of the first microcontroller 18, which forms on it a binary sequence of pulses containing service information about the measured and stored in the mode. “The transmission of information to moving objects 2 (first cycle) of the power values of the received information radio signals during the first cycle of transmitting information 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 various five preset frequencies of the retransmission of this base tion 1. This generator 15 controlled by the signals acting on the output of the first electronic switch 14, produces high frequency keyed signal which is provided to a respective switching input of the second electronic switch 20. The second electronic switch 20

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 information measured during the first cycle of transmitting information to moving objects 2 power values of the received information radio signals at each of these neighboring base stations 1.

At the same time, at each of these neighboring base stations 1, the first receiving antenna 6 receives service radio signals emitted from base stations 1 that are adjacent to the indicated neighboring base stations 1. Received service radio signals are fed to the inputs of the first bandpass filters 7, which select them by 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 realize 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 service radio signals of the corresponding operating frequencies by comparing the values of their power with a threshold p

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 power value RTm min.

radiated information radio signals and generates at the control input of the adjustable power amplifier 16 a control signal, in accordance with which the power of the radiated information radio signals takes the value Pqw35l.

By analogy with the above, the transceivers 4 included in 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 I (first cycle) mode.

The “Adjustment of the radiation power of base stations 1 (first cycle) mode has a fixed duration that is the same for 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, the transceivers 4, which are part of each base station 1, operate during the second and all subsequent cycles of transmitting information to moving objects 2.

At each of the base stations 1, which are not sources of transmitted information, at the end of the mode “Adjusting the radiation power of base stations 1 (fifth cycle), the first microcontroller 18, when transmitting other information radio signals to moving objects 2, returns transceiver 4 to the mode“ Information transmission to moving objects 2 (first measure).

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 considered that the transceivers 4, which are part of the base stations 1, simultaneously receive information radio signals emitted from neighboring base stations 1 and emit them 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 generated 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 block 26, the output

the signal of which is fed to the input of the second integrator 27, which at the input of the second ADC 28 generates a signal proportional to the power of the received informational radio signal in accordance with formula (2). 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 verifies the conditions of the Rpr Rpr.min and, if implemented, makes a decision on

the presence at the input of the radio 5 of the information radio signal of the corresponding operating frequency, otherwise the second microcontroller 29 makes 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 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, the radios 5 located on the moving objects 2, also receive service radio signals emitted from the base stations 1, in the zones 3 of which they are located. Moreover, in each radio 5, the second microcontroller 29, based on the analysis of received service radio signals, blocks the display of service information on the indicator 30.

Thus, the transceivers 4 included in the base stations 1, in accordance with the information contained in the blocks 19 of the task, 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 adjacent to the previous base stations 1, simultaneously receive the information signals radiated from the previous base stations 1 and emit them on the corresponding preset slaves other frequencies. Wherein

the transmission of information from the base station 1, which is the source of the transmitted information, to the base stations 1, in the 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, radiation from each base station 1 of service radio signals containing information about the measured power values, reception of the specified service radio signals and adjustment at each of these neighboring base stations 1 of radiation power informational radio signals according to the measured values of the power of informational radio signals received at base stations 1, which are adjacent to the specified neighboring base station 1, and emitted from this base station 1, at the given operating frequencies carry out the indicated manner only five times, and each time the radiation of radio signals from each base station 1 is carried out at one of five preset from seven preset operating frequencies, different from other radio frequencies set at this base station 1 s emitted from this base station 1, and distinct from the respective further defined operating frequencies of radio signals emitted from adjacent base stations 1.

Thus, the described technical solution allows, in contrast to the prototype, to transmit information to mobile objects 2 located within the service area without the use of a switching center and fiber optic communication lines connecting the switching center to 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.
