The technical solution relates to radio communications, and in particular to methods of transmitting information on moving objects from stationary objects in the initial paragraph of the General route of moving objects.

There is a method of satellite communication (see, for example, Owhali, Niestetal, Usarc, Hardon Aguilar. Radio communication. Edited Avelona. - M.: Hot line - Telecom, 2001, s-279), namely, that transmit radio signals with a fixed object, take these radio signals on an artificial Earth satellite, transmit the radio signals from artificial Earth satellite, receive these radio signals on a movable object, transmit radio signals with a mobile object, take these radio signals on an artificial Earth satellite, transmit the radio signals from artificial Earth satellite, receive these radio signals to a stationary object.

This method allows a great range of radio communication between the terrestrial fixed object and the moving objects on the Earth's surface or near it, regardless of their routes, however, requires removal of radio communication satellites in earth orbit and motion control and operation, which complicates the method.

However, the considerable height of the orbits of satellites (from hundreds of kilometers in systems with low on alosaimi orbits up to tens of thousands of kilometers in systems with high-elliptical and geostationary orbits - see, for example, Umoristi, War, Lamnidae. Future satellite communication systems. - M.: Hot line - Telecom, 2000, p.71) require on the space station, as well as on stationary and mobile objects transceiver devices with large capacity, equipped vysokonapolnennyh antennas.

However, increasing the power transmitting devices causes the deterioration of their mass and size parameters, decreased immunity of various electronic funds placed on stationary and moving objects, as well as the reduction of electromagnetic safety of people on the immovable and movable objects.

The above drawback in combination with disabilities create antennas with higher gain leads to an increase in the geometric space occupied by this system with radio (local coverage of the earth surface by a single beam satellite repeater reach hundreds of kilometers in diameter - see ibid, p.78-110), which reduces the efficiency of the method in the simultaneous operation of multiple radio systems.

The term “volume of geometric space” describes one of the three major (along with the bandwidth and time) components of the radio-frequency space occupied by the system happy is ovasi (see Naagin. Topical issues of monitoring in the Russian Federation. - M.: Radio and communication, 2000, C.11-12).

There is a method of radio communication between ground control station and the aircraft (see, for example, Pascalidou, Paisano. The maintenance of avionics. The Handbook. - M.: Transport, 1990, p.88-92), namely, that transmit radio signals with ground control point, take these radio signals to aircraft, transmit radio signals from the aircraft, take these signals to ground control points.

This method does not require solving complex problems inherent in satellite radio, and allows a great range of radio communication with multiple aircraft performing flight at high altitudes on arbitrary paths.

However, the communication distance with low-flying aircraft significantly decreases as a result of the influence of reflection of electromagnetic waves from the Earth's surface (see, for example, theoretical foundations of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s).

To increase the range of radio communication it is necessary to increase the power transmitting-receiving stations located at the ground control tower and aircraft, and also the directivity of these antennas receiving erediauwa stations.

However, increasing power transceiver stations causes the deterioration of their mass and size parameters, decreased immunity of various electronic funds placed in the CWP and aircraft, as well as the reduction of electromagnetic safety of people on the control tower and aircraft.

The above drawback in combination with disabilities create antennas with higher gain leads to an increase in the geometric space occupied by the communication system, which reduces the efficiency of the method in the simultaneous operation of multiple radio systems.

Meeting the technical challenge is to improve mass and size parameters transceiver stations mobile objects and stationary objects in the initial paragraph of the General route of moving objects, increasing the noise immunity of various electronic funds allocated to the fixed and mobile objects, increasing electromagnetic safety of people on the immovable and movable objects, the reduction in the geometric space occupied by the radio system, and hence, increase the efficiency of the method in terms of the simultaneous exploits and several radio communication systems based on the implementation of the radio using discharged from the first movable object low intermediate transceiver stations, equipped with omnidirectional antennas, and discharged intermediate transceiver station after the radio communication between mobile objects and stationary object destroy.

The solution of the technical problem in the way of radio communication between mobile objects and stationary object in the initial paragraph of the General route of movement of movable objects, namely, that transmit at a given operating frequency of the radio signals from a stationary object are specified operating frequencies of the radio signals for mobile objects, is achieved by the fact that since the time of the first removal of the first moving object from a stationary object at a distance determined by the given ranges of validity radio station, placed on a stationary object, and the intermediate transceiver stations, the first mobile object shall reset the intermediate transceiver stations, with radio transmission with a fixed object on moving objects is that accept transferred from a fixed object, the radio signal of the first reset with the first movable object intermediate transceiver station and transmit them, accept transferred from the first discharged from the first movable object intermediate transceiver station radio signals on the second with Rosenau with the first movable object intermediate transceiver station and transmit them similarly carry out reception and transmission of radio signals using other discarded at a later time from the first movable object intermediate transceiver stations in the direction of transmission of the radio signals from the reset intermediate transceiver stations in earlier times to reset at a later time, taken on the first movable object by radio signals are radio signals transmitted from the last reset with the first movable object intermediate transceiver station to other mobile objects, following the General route of the first mobile object, receive the radio signals transmitted from reset with the first movable object intermediate transceiver stations, at the end of radio communication between mobile the object and a fixed object destroy discharged from the first movable object intermediate transceiver station.

When transmitting radio signals from a fixed object on moving objects specified operating frequency of the radio signals received at each reset with the first movable object intermediate transceiver station, in addition to the first reset with the first movable object intermediate transceiver station is specified operating frequency of the radio signal is transmitted from the intermediate transceiver station, flushed with the first movable object closest to the time of reset of this intermediate transceiver station earlier point in time, the specified operating frequency of the radio signals received at the first reset with the first movable object intermediate transceiver station is specified operating frequency of the radio signals transmitted from a fixed object, the specified operating frequency of the radio signals received on the first movable object is specified operating frequency of the radio signals transmitted from the last reset with the first movable object intermediate transceiver station.

The term “moving object” is generally accepted (see, for example, Soloviev Y.A. satellite navigation System. ): Eco-trends, 2000, p.39). To moving objects include, in particular, means of land, water and air transport, equipped with radio communication, and moving objects can not only be in motion, but also to make a stop.

The method consists in the following.

Consider a situation in which a fixed object 1 is ground control station, the first mobile object 2 and the second movable objects 47 are low-flying aircraft apt the drugs, for example, helicopters or airships.

The routes of movement of the first movable object 2 and the second movable objects 47 the same.

The second movable objects 47 follow the General route of the first mobile object 2.

The term “low flying aircraft” is generally accepted (see, for example, Radio systems. Edited by Prof. Umetalieva. - M.: Higher school, 1990, s). The first movable object 2, in particular an aircraft is flying at low levels, if the condition (see theoretical bases of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s):

where C is the speed of light; hand- the height of the first transmitting antenna 23 transmitting station 3, located on stationary object 1; hb- the height of the first receiving antenna 24 of the first radio receiving station 4, located on the first movable object 2; d - distance between a fixed object 1 and the first movable object 2.

The expression (1) is true, if the condition of mirror reflection of radio waves from the underlying surface (see ibid., s):

where ψ - angle slip; δ - the height of the irregularities of the underlying surface.

For definiteness, let us assume that the surface on which p is the surface of the Earth, is a mirror reflecting the horizontal plane, i.e. condition (2) is performed.

On stationary object 1 is placed radio station 3.

On the first movable object 2 is placed first radio receiving station 4 and N intermediate transceiver stations 5 with numbers n=1,2,... , N, where n is a positive integer.

In the General case, the first movable object 2 at each point of the reset can be reset on more than one intermediate transceiver stations 5.

Let us assume that the first movable object 2 at each point of the reset discharge only one intermediate transceiver station 5.

Earlier time points reset intermediate transceiver stations 5 with the first movable object 2 are in the intermediate transceiver station 5 with lower numbers:

where tntν - time reset n th ν th intermediate transceiver stations 5, respectively; ν =1,2,... ,N be positive integers.

On the first movable object 2, the reference time tbconduct from the time, in which the first movable object 2 was the starting point Of your route.

In the initial paragraph On the route of movement of the first movable object 2 and the second movable is bjectiv 47 is the stationary object 1 (Fig 1).

Last reset from the first movable object 2 intermediate transceiver station 5 is an intermediate transceiver station 5, the discharge of which is carried out in the most recent point in time:

where nmax=1,2,... N.

The range of the n-th reset with the first movable object 2 intermediate transceiver station 5, except the last reset with the first movable object 2 intermediate transceiver station 5 (n=nmax), equal

where Pn)- power radio signals transmitted from the n-th reset intermediate transceiver station 5; Pn+1 pminsome threshold value, which characterizes the sensitivity of the (n+1)-th reset intermediate transceiver station 5; hnhn+1- the height of the second transmitting antenna 43 n-th and the second receiving antenna 34 (n+1)-th reset intermediate transceiver stations 5, respectively.

The range of the last reset with the first movable object 2 intermediate transceiver station 5 is equal to

where- power radio signals transmitted since the last reset with the first movable object 2 intermediate transceiver station 5; Pb. some threshold value, which characterizes the sensitivity of the first radio receiving station 4 of the first movable object 2;- the height of the second transmitting antenna 43 last reset with the first movable object 2 intermediate transceiver station 5.

The range of radio broadcast stations 3 a stationary object 1 is equal to

where Rand [Izl]- power radio signals transmitted from a fixed object 1; Rn PR min|n=1some threshold value, which characterizes the sensitivity of the first discharged from the first movable object 2 intermediate transceiver station 5; hn|n=1- Vesterbrogade second receiving antenna 34 of the first discharged from the first movable object 2 intermediate transceiver station 5.

Under the height of the antenna understand the distance to under the antenna point of the underlying surface.

The height hathe location of the first transmitting antenna 23 transmitting station 3 is fixed and is determined by the unique design and layout a stationary object 1 and the radio station 3.

The height hbthe location of the first receiving antenna 24 of the first radio receiving station 4 is changed in the range of hbminto hbmax. M is the minimum value of height h bminis achieved when the first movable object 2 is located on an underlying surface and is determined by the characteristics of the structures and layout of the first movable object 2 and the first radio receiving station 4. The maximum value of the height hbmaxdoes not exceed the sum of the values of hbminand maximum flight altitude Hbmaxthe first movable object 2.

Height hnthe location of the second receiving antennas 34 and second transmitting antennas 43 discharged from the first movable object 2 intermediate transceiver stations 5, range of values of hnminto hnmax. The minimum value of the height hnminis achieved when the n-th intermediate transceiver station 5 is located on an underlying surface and is determined by the design features of this intermediate transceiver station 5. The maximum value of the height hPMOcorresponds to the time of discharge of the n-th intermediate transceiver station 5 with the first movable object 2 and does not exceed the value of hbmax.

Since the routes of movement of the second moving objects 47 coincide with the route of movement of the first movable object 2, we assume that the minimum of hminand the maximum hcmaxthe elevation values of the location of the third receiving antenna 49 of the second radio receiving stations 48, placed second under ijnih objects 47, coincide respectively with the minimum of hbminand the maximum hbmthe elevation of the location of the first receiving antenna 24 of the first radio receiving station 4, located on the first movable object 2. In addition, we assume that the sensitivity of the second radio receiving stations 48 is equal to Pwith so min.

Formula (1), (6) remain valid when replacing them in the settings of the first radio receiving station 4 on the parameters of the second radio receiving stations 48.

Expression(1), (2), (5)-(7) are approximate and do not take into account the geometry of the object 1, the first movable object 2, the second moving objects 47 and the intermediate transceiver stations 5.

Considering the above, we assume that for all n fair equality

From expressions (5), (6) it follows that under the conditions (8)-(11) the minimum range of the intermediate transceiver stations 5 equal

For given values of R[Izl]Pprminand hmintaking into account formulas (12) range intermediate transceiver stations 5 set equal

The range of radio broadcast stations 3 set specified by the output values of the ranges of validity of the intermediate transceiver stations 5, for example, by the formula:

In General, when moving along the first route of the mobile object 2 and the second movable objects 47 can make a stop at arbitrary time intervals.

Assume that the first movable object 2 carries on from the initial point O, which is the stationary object 1, the vertical height hbmaxand then performs a horizontal flight at a height of hbmaxwith constant velocity Vbalong the x-axis in the direction of in the direction of increasing values of x; the maximum distance from a fixed object 1 to the first movable object 2 is equal to dbmaxand characterizes the length of the route of movement of the first movable object 2.

Before time tbminfirst remove the first movable object 2 on object 1 at a distance of dbminc of the first movable object 2 reset intermediate transceiver stations 5 do not exercise. While the implementation of the method lies in the fact that transmit radio signals from a fixed object 1, receive these radio signals on the first movable object 2.

The value of dbmindetermined by specified distances of Ra=Rn=Rminaction radio transmitting station 3 and the intermediate transceiver stations 5.

In particular, the value of bminyou can set

where k11 - factor, taking into account the approximate nature of the applied formulas.

From the moment of time tbminfirst remove the first movable object 2 on object 1 at a distance of dbminfrom the first movable object 2 discharge intermediate transceiver stations 5 intervals range defined by the given ranges of validity transmitting station 3 and the intermediate transceiver stations 5.

Effect of the assumptions interval reset intermediate transceiver stations 5 with the first movable object 2 can be

where k21 - factor.

Reset the first intermediate transceiver station 5 with the first movable object 2 is carried out in a time tbminfirst remove the first movable object 2 on object 1 at a distance of dbmin.

The distance from a fixed object 1 to the first movable object 2, which discharge the intermediate transceiver stations 5, can be measured on the first movable object 2 using inertial or Doppler systems reckoning (see Aeronautical radionavigation: a Handbook. Edited Ass. M.: Transport, 1990, p.6-8).

When the previously specified characteristics of movement of the first movable object 2 reset the n-th intermediate transceiver station 5 is carried out in time

and

where τhmax- vertical lifting of the first movable object 2 from the starting point Of the height hmax.

Formula (17) is due to the fact that the intervals in range Δ dndetermine the maximum possible distance between two intermediate transceiver stations 5 discharged from the first movable object 2 in the next time.

Formula (18) is due to the fact that the range of dbmindetermines the maximum distance from the first mobile object 2 to object 1, corresponding to time tbmin.

In the General case, the first movable object 2 can move along a complex route. In particular, it can first be removed from a fixed object 1, and then to approach him, then again be removed and closer, etc. With the first movable object 2 may repeatedly pass through the start point Of which is the stationary object 1, and, therefore, repeatedly placed him at a distance < dbmin. However, resetting the intermediate primape edusa stations 5 with the first movable object 2 is not carried out only until the time of the first removal of the first movable object 2 on object 1 at a distance of d bmin. From this point in time with the first movable object 2 discharge intermediate transceiver stations 5 intervals range defined by the given ranges of validity transmitting station 3 and the intermediate transceiver stations 5, and the intermediate reset transceiver stations 5 is carried out and if the result of movement of the first movable object 2 on the route distance to a stationary object 1 will again become less than the value of dbmin.

If the wind speed is negligible, the velocity Vbthe movement of the first movable object 2 is so small that it does not cause significant disturbance of air masses, the trajectory of the fall intermediate transceiver stations 5, you can take vertical. While the aerodynamic properties of the structures of the intermediate transceiver stations 5 should not have any special features that cause a significant deviation of the trajectories of falling from a vertical.

After falling on the surface of the intermediate transceiver station 5 remain motionless.

The factor k2take into account the possible inaccuracy of the scatter intermediate transceiver stations 5, due to the influence of various factors.

There are two characteristic cases:

When the movement of the first movable object 2 on the route, the duration of which is equal torun both conditions (19), (19 b). In each moment of time is only one of the specified conditions. In addition, due to the irreversibility of time, if it is condition (19 b), the condition (19) will not come. Thus, from the above it follows that the method can be carried out only in one way.

In the first case, (19) with the first movable object 2 reset intermediate transceiver stations 5 do not exercise. The implementation of the method in this case considered above.

Consider the implementation of the method in the case of (19 b), which corresponds to the reset intermediate transceiver stations 5 with the first movable object 2.

With a fixed object 1 transmit radio signals. Accept transferred from a fixed object 1 signals to the first (n=1) dropped from the first movable object 2 intermediate transceiver station 5 and pass them. Accept transferred from the first (n=1) dropped from the first movable object 2 intermediate transceiver station 5 radio signals for the second (n=2) dropped from the first movable object 2 intermediate transceiver station 5 and pass them. Similarly, the implementation of which enables the reception and transmission of radio signals using other discarded at a later time from the first movable object 2 intermediate transceiver stations 5 (n=3,4,... nmax) in the direction of transmission of the radio signals from the reset intermediate transceiver stations 5 in earlier times tnto reset at a later time tν where ν >n. Take the first movable object 2, the radio signal transmitted from the last (n=nmax) discharged from the first movable object 2 intermediate transceiver station 5.

Each intermediate transceiver station 5 starts to operate at the time of reset and continues to function before and after contact with the underlying surface.

At lower intermediate transceiver stations 5 of their range and the range of radio broadcast stations 3 are reduced, but in accordance with formulas (5)-(14) does not become less than the value of Rmin.

Some time after the start of movement of the first movable object 2 start moving the second movable objects 47. Their routes coincide with the route of movement of the first movable object 2. When the second movable objects 47 follow the first moving object 2, not ahead of it.

On the second movable objects 47, following the General route of the first mobile object 2, carry out the reception of radio signals transmitted from a fixed object 1 and discharged from the first movable object 2 is tick transceiver stations 5.

If the first movable object 2 has not yet dropped any intermediate transceiver station 5 (case 19), and the second movable objects 47 have already begun to move along the route, the second movable objects 47 carry out the reception of radio signals transmitted from a fixed object 1 (the characteristic inherent in the prototype, and therefore it is included in the General part of the stated claims). If the first movable object 2 have reset the intermediate transceiver stations 5 (case 19, b) and second movable objects 47 have already begun to move along the route, the second movable objects 47 depending on their location on the route, carry out the reception of radio signals transmitted from a fixed object 1 and discharged from the first movable object 2 intermediate transceiver stations 5.

When the movement of the first movable object 2, the second moving objects 47 and discharged intermediate transceiver stations 5 occurs Doppler effect, the negative impact on the communication quality can be resolved by rational choice of the frequency characteristics of signals and devices transmitting station 3, the first radio receiving station 4, the second radio receiving stations 48 and intermediate transceiver stations 5.

In the process in terms Perez the Chennai area to determine discharge points intermediate transceiver stations 5, you must take into account the information about the height field terrain. For this purpose, the first movable object 2 can be used in the review and comparative systems of navigation (see Aeronautical radionavigation: a Handbook. Edited Ass. - M.: Transport, 1990, p.8-9).

The underlying surface may be the surface of the water. In this case, when implementing the method, you must keep the intermediate transceiver stations 5 on the surface of the water after a fall. In addition, when specifying ranges of validity transmitting station 3 and the intermediate transceiver stations 5, consider the excitement of the water surface and possible flow.

To reduce the amount of geometric space occupied by the communication system, and consequently, to improve the efficiency of the method in the simultaneous operation of multiple radio communication systems necessary for the completion of the radio connection between the mobile objects (the first movable object 2 and the second movable objects 47) and a fixed object 1 to destroy discharged from the first movable object 2 intermediate transceiver station 5.

The destruction of the dropped intermediate transceiver stations 5 can significantly reduce the amount of each of them, because the result of the destruction of the small and incapable of functioning parts of structures intermediate preempted the participating stations 5 can be stacked more densely.

The term “operating frequency” understand the value of carrier frequency oscillations, Central or any other characteristic frequency band of radio signals. When this band of frequencies of the radio signals, corresponding to different operating frequencies do not overlap.

For an arbitrary route of movement of the first movable object 2 and the second movable objects 47 the specified operating frequencies of the radio signals transmitted at the same time with a fixed object 1 and each of the intermediate transceiver stations 5 discharged from the first movable object 2 must be different:

When transmitting radio signals from a fixed object 1 on the first movable object 2 and the second movable objects 47 the specified operating frequencyradio signals received on the n-th reset with the first movable object 2 intermediate transceiver station 5, except for the first (n=1) dropped from the first movable object 2 intermediate transceiver station 5 is specified operating frequency fn-1, radio signals transmitted from the (n-1)-th intermediate transceiver station 5 discharged from the first movable object 2 at the time tnreset this (nth) intermediate transceiver station 5 earlier point in which the time t n-1.

Specified operating frequencyradio signals received at the first (n=1) dropped from the first movable object 2 intermediate transceiver station 5 is specified operating frequency faradio signals transmitted from a fixed object 1:

Specified operating frequencyradio signals received on the first movable object 2 is specified operating frequencyradio signals transmitted from the last (n=nmax) discharged from the first movable object 2 intermediate transceiver station 5, if the first movable object 2 is reset at least one intermediate transceiver station 5, or otherwise specified operating frequency faradio signals transmitted from a fixed object 1 (the characteristic inherent in the prototype, and therefore it is included in the General part of the stated claims):

Specified operating frequencies of the radio signals received at the second mobile objects 47, following the General route of the first mobile object 2 are specified operating frequencies of the radio signals transmitted from a fixed object 1 and discharged from the first paragraph is movable partition object 2 intermediate transceiver stations 5.

The capacity of the radio signals received at the second mobile objects 47, depends on the location of the second mobile objects 47 on the route.

From the above it follows that the operating frequencies of the radio signals transmitted from a fixed object 1, the radio signal received at the intermediate transceiver stations 5 and transmitted from the radio signals received at the second mobile objects 47 can be fixed.

However, when the discharge from the first movable object 2 regular (n=nmax) intermediate transceiver station 5 desired operating frequencyradio signals received on the first movable object 2 must coincide with the given operating frequencyradio signals transmitted from a given (n=nmax) intermediate transceiver station 5.

In addition, for the implementation of radio communication between a fixed object 1 and the first movable object 2 in the situation of (19), which have not dropped a single intermediate transceiver station 5, the specified operating frequencyradio signals received on the first movable object 2 must coincide with the given operating frequency faradio signals transmitted from a fixed object 1.

All items and blocks that are included with the system, presented in figure 1-7 are known and described in literature.

As the meter 11 speed on the first movable object 2, which, in particular, low-flying aircraft, can be used Doppler velocity meter and drift angle or inertial velocity meter (see Aeronautical radionavigation: a Handbook. Edited Ass. - M.: Transport, 1990, p.6-8).

As block 8 jobs can be used any known and described in the literature digital input devices (see, for example, Shevkoplyas BV Microprocessor structure. Engineering solutions. - M.: Radio and communication, 1993, p.27).

As unit 6 controls can be used microprocessor system with analog and digital inputs and outputs, which include a clock generator, memory devices, analog-to-digital and digital-analog converters, and other devices (see, for example, Horowitz, Whill. Art circuitry. - M.: Mir, 1993, s-295), not shown in figure 2.

As each of the measures 57 power can be used connected in series block squaring and integrator (see, for example, Gandal, Aperol. Applied analysis of random data. - M.: Mir, 1983, p.143).

Unit 9 reset is used to implement the reset intermediate PR is emuparadise stations 5 with a specified interval in range.

As the conveyor 11 is applied belt conveyor with horizontal closed track (see, for example. The conveyors. The Handbook. Under the General editorship Uairen. - L.: engineering, 1984, p.4-9).

The conveyor 11 is designed to move the intermediate transceiver stations 5, placed in the supporting elements 13, in the direction of the hole 18.

The actuator 10 is designed for driving the belt 12 of conveyor 11 with a speed corresponding to the signals generated by the control block 6.

The actuator 10 is automated. Systems of automated control of electric drives provide a given angular velocity of the shaft of the motor in accordance with external control signals, which, depending on the type of motor and control system can be analog or digital (see, for example, Polytechnical dictionary. The editorial Board.: Awesomse (editor-in-chief) and others - 3rd ed., Rev. and supplementary): P “Great Russian encyclopedia”, 1998, s). The design of the actuator is known (see, for example, the Conveyors. The Handbook. Under the General editorship Uairen. - L.: engineering, 1984, p.87-91).

Construction of block 9 reset provides unrestricted movement sub the internal transceiver stations 5 to the hole 18 when they are flushed.

The size of the holes 18 exceed overall dimensions of each intermediate transceiver station 5 in conjunction with the attached stowed parachute 15.

The number of bearing elements 13, which is in the initial position is equal to N the number of intermediate transceiver stations 5, placed on the first movable object 2.

The upper position of the bearing elements 13 corresponds to their position on the longitudinal axis of symmetry of the conveyor 11.

In the General case, in block 9 reset for loading the intermediate transceiver stations 5 can be applied well-known boot device (see, for example, the Conveyors. The Handbook. Under the General editorship Uairen. - L.: engineering, 1984, s-100).

The bearing elements 13 attached along the conveyor 11C interval equal to Δ ln.

Fixed in the supporting elements 13, the magnets 16 is a plate made of hard magnetic materials.

Intermediate transceiver station 5 is placed in the supporting elements 13 in the vicinity of the magnets 16, the magnetic field which provides the closure of the contacts of reed switches 45, however, is negligible in its impact on the movement of the intermediate transceiver stations 5 when they are flushed.

The first transmitting antenna 23, the first receiving antenna 24, the second receiving antenna 34 and the second transmitting ant the nna 43 are non-directional.

Construction of the intermediate transceiver stations 5 will be developed with consideration of impact loads that occur when confronted with the underlying surface (see, for example, Webcamporn. Vibration and shock in radio. - M.: Soviet radio, 1971, s-216). In this regard, the second receiving antenna 34 and the second transmitting antenna 43 of the intermediate transceiver stations 5 can be placed inside the high impact of the radio waves buildings, made for example of PTFE.

Parachutes 15 serve to reduce the speed of falling intermediate transceiver stations 5 and, consequently, to reduce the shock loads that occur when they collide with the underlying surface.

The parachutes 15 in the supporting elements 13 eliminates the tangling of legs 14 when the reset intermediate transceiver stations 5.

The physical and geometric characteristics of parachutes 15 (permeability, elasticity fabric dome, the shape and size of the dome, the presence and shape of the cutouts and other) is determined based on the weight of the intermediate transceiver stations 5 and the required dynamics of parachutes 15 (see, for example, Wasiljev, Vnesheco, Whatamango. Dynamics of parachute systems. - Kyiv, Odessa: “high school”. Head publishing house, 1985). Design and characteristics of parachutes 15 assume their automatic disclosure in the intermediate reset PR is emuparadise stations 5.

The source of 19 messages can serve as a device to sequentially output the digital signals, and the first recipient of 31 messages and second receivers 62 messages to the serial digital input signals (see, for example, Digital and analog integrated circuits. The Handbook. Edited Svechenovskoj. - M.: Radio and communication, 1990, s).

The voltage of each of the second radio receiving station 48 produces an onboard power supply system of the corresponding second movable object 47, not shown in figure 1-7.

Each of the battery 46 is designed to generate a voltage corresponding to the intermediate transceiver station 5. The capacity of the battery 46 is set on the basis of the power consumption of the corresponding intermediate transceiver station 5 and the duration of the operation.

The frequencies of the first radio receiving station 4, the second radio receiving stations 48 and intermediate transceiver stations 5 are specified operating frequencies of the radio signals received respectively at the receiving station 4, the second radio receiving stations 48 and intermediate transceiver stations 5.

The terms “transmission frequency” and “frequency of use” of any device are generally accepted (see, for example, Gromakov Y.A. Standards and mobile radio systems. ): Eco-Trends, 2000, s).

The term “controlled oscillator is generally accepted (see, for example. Theoretical bases of radar. Edited Vaitulevich. - M.: Soviet radio, 1978, s). The oscillation frequency generated by the controlled oscillator is determined by the voltage acting on its control input. In this case, the controllable oscillator is controlled oscillator voltage. Generators driven by voltage, are known and described in the literature devices (see, for example, Horowitz P., hill. U. Art circuitry. In 3 volumes: T.1. TRANS. from English. - 4th ed. revised and enlarged extra - M.: Mir, 1993, s).

Consider the implementation of the method using the system presented in figure 1-7.

First podmenyushek 2 and the second movable objects 47 are in the initial paragraph About the General route. In the initial paragraph About the General route of movement of the first movable object 2 and the second movable object 47 is fixed to the object 1.

The conveyor 11 is shown in an initial state in which the bearing element 13, closest to the hole 18, must pass the path equal to the lbminto the point where there is separation of the corresponding intermediate transceiver station 5 from the support member 13 and begins her fall.

This is the ratio of:

The gain of the first low-noise amplifier 26, the second low-noise amplifiers 36 and third low-noise amplifier 51 is set so that the sensitivity of the first radio receiving station 4, the intermediate transceiver stations 5 and second receiving stations 48 amounted to Pprmin.

The gain of the first amplifier 22 and second power amplifiers 42 power set so that the power of radio signals transmitted from a fixed object 1 and the intermediate transceiver stations 5, was equal to R[Izl].

Then taking into account expressions (5)-(14) the range of radio broadcast stations 3 and intermediate transceiver stations 5 is equal to Rmin.

Let us assume that the transmission frequency of the n-th intermediate transceiver station 5 is equal to

where Δ - the offset frequency.

In block 8 of the job, enter values in the ranges Rminsteps intermediate transceiver stations 5.

Unit 6 reads the code from the outputs of block 8 of the job, containing information about the specified values of the distances Rminactions, and determines the formulas (15), (16) the value of dbminand Δ dn.

The contacts of the reed switch 45 of each of the intermediate transceiver stations 5, placed in the supporting elements 13, are closed in the magnetic field of the magnet 16. The conclusions of the winding of an electromagnetic relay 44 applied voltage of battery 46. The contacts of the electromagnetic relay 44 are open. Transceiver unit 32 is de-energized. About erotoca transceiver station 5 does not function.

the first movable object 2 starts to execute from a common start point Of the vertical height hbmaxand then performs a horizontal flight at a height of hbmwith constant velocity Vbalong the x-axis in the direction of in the direction of increasing values of X.

The block 6 management continuously reads from the outputs of the meter 7 speed with the speed of movement of the first movable object 2 and using formulas (17), (18) determines the points in time of the reset intermediate transceiver stations 5.

Let us assume that the acceleration of the first movable object 2 to a speed of Vbwith the beginning of the horizontal movement is negligible. If the acceleration cannot be neglected, the time tbminreset the first intermediate transmitting-receiving station 5 is determined from the solution of the equation

At timecomplete the lifting of the first movable object 2 to a height of hbmaxunit 6 control generates the control signal by which the actuator 10 causes the belt 12 of conveyor 11 in the moving speed:

The movement of the tape 12 on the longitudinal axis when metrie conveyor 11 is in the direction of the hole 18 (figure 2).

The time during which the speed of the tape 12 reaches the value Ub, is negligible.

Before time tbminfirst remove the first movable object 2 on object 1 at a distance of dbminc of the first movable object 2 reset intermediate transceiver stations 5 is not carried out (case 19, a).

In this case, the radio transmission from a fixed object 1 on the first moving object 2 is as follows.

On its second input receives the oscillation frequency fagenerated by the first local oscillator 21. The value of frequency faasked by formula (26). Amplitude-shift keyed signal with the output of the first Converter 20 frequency is fed to the input of the first amplifier 22 power, the output of which is fed to the input of the first transmitting antenna 23. The first transmitting antenna 23 transmits at a given operating frequency fathe corresponding signal.

The first receiving antenna 24 of the first radio receiving station 4, located on the first movable object 2 receives the radio signal transmitted by a radio transmitting station 3. The output signal from the first receiving antenna 24 post which becomes the input of the first bandpass filter 25, providing selectivity image channel (see, for example, a Receiving device. Edited Vietrova. - M.: Soviet radio, 1974, s). The output signal of the first bandpass filter 25 is fed to the input of the first low-noise amplifier 26, the output of which is fed to the first input of the second inverter 27 frequency. On its second input receives the oscillation frequency f’b+fbgenerated by the controlled oscillator 28. The value of the frequency f’bthe received radio signals is set by the formula (26). The signal of the intermediate frequency fbnfrom the output of the second inverter 27 frequency is fed to the input of the first amplifier 29 intermediate frequency, the output of which is fed to the input of the first demodulator 30. The binary sequence of pulses corresponding to the transmitted message arrives from the output of the first demodulator 30 to the input of the first recipient 31 messages.

Some time after the beginning of the movement route of the first mobile object 2 from the initial point Of starting the movement of the second moving objects 47, routes with the same route of movement of the first movable object 2.

The second movable objects 47 can move along the route in an arbitrary order, for example, overtaking each other, but to overtake the first movable object 2 on the don't have to.

The maximum number of the second mobile objects 47 limited and is associated with a maximum duration of reset intermediate transceiver stations 5.

If the first movable object 2 has not yet dropped any intermediate transceiver station 5 (case 19), the transmission of radio signals from a fixed object 1 on the second movable object 47 is as follows.

The signal of the intermediate frequency fcnfrom the output of the fifth inverter 52 frequency is fed to the input of the third amplifier 54 intermediate frequency, the output of which is fed to the inputs of all fourth is volosovych filter 56. On the basis of formulas (25) the frequency of the fourth bandpass filter 56 of the n-th channel 55 processing equal. Bandwidth fourth bandpass filters 56 do not overlap. The signals from the outputs of the fourth bandpass filters 56 are received in the corresponding switched inputs of the analog switch 59 and to the inputs of the respective gauges 57 power. In each channel 55 processing the output signal from the meter 57 power is fed to the input of analog-to-digital Converter 58, which produces a binary code corresponding to the value of the signal received on the corresponding given operating frequency. The microcontroller 60 reads the binary code outputs all analog-to-digital converters 58 and defines thereon a predetermined operating frequency of the received radio signal maximum power. (In this case, the specified operating frequency of the received radio signal is the maximum power is specified operating frequency fathe radio signal transmitted from a fixed object 1.) Then the microcontroller 60 generates the control inputs of the analog switch 59 control signals, by which the analog switch 59 connects the output of the fourth bandpass filter 56 corresponding to a given operating frequency of the received radio signal maximum mo is ness, to the input of the second demodulator 61. The binary sequence of pulses corresponding to the transmitted message arrives from the output of the second demodulator 61 to the input of the second receiver 62 messages.

The value of the intermediate frequency of the first radio receiving station 4, the second radio receiving stations 48 and intermediate transceiver stations 5 ask given the known limitations (see, for example, a Receiving device. Edited Vietrova. - M.: Soviet radio, 1974, s).

At time tb=tbminas a result of movement of the belt 12 of conveyor 11 closest to the hole 18 of the bearing element 13 occupies a position in which there is separation of the corresponding intermediate transceiver station 5 from the support member 13 and begins its decline. This is reset the first intermediate transceiver station 5 with the first movable object 2. (Prior to discharge from the first movable object 2 of the following intermediate transceiver station 5 this intermediate transceiver station 5 is at the same time last reset with the first movable object 2 intermediate transceiver station 5).

When the contacts of the reed switch 45 this intermediate transceiver station 5 is open. The contacts of the electromagnetic relay 44 take normally closed. On prempreeda the rd unit 32 receives a supply voltage. The intermediate transceiver station 5.

Simultaneously, the control block 6 generates the control signal, whereby the oscillation frequency generated by the controlled oscillator 28, takes the value ofmoreover , in accordance with the formula (23):
