The imaging unit 35 of the control signals (see Fig. 3) is designed to generate control information of discrete and continuous signals and the enable signal transmitter 26 in the emission mode.

Control of discrete signal is a binary sequence of symbols with parameters (amplitude, clock frequency, pulse duration), the same options real binary information sequence received at the input manipulation peredatchika voltage, for example, a sawtooth or triangular shape, the amplitude of which varies from a minimum Uminto the maximum Umaxvalues. Values Uminand Umaxmeet UminMSand UmaxMSreal analog signals to the modulation input of the transmitter from the source of continuous (analog) information. The pulse repetition frequency of the sawtooth shape is selected within the standard channel, for example 1 kHz. The formation time (duration) of both discrete and continuous control signals equally and is set in advance. FGC 35 is implemented based on the scheme shown in Fig. 3. In Fig. 12 shows the timing chart explaining the operation of FGC.

Start FGC 35 is carried out when the input signal is non mobile station, received from FSNS 32. After the time required for signal transmission, FGC 35 at its output begins to form discrete control signal for a specified time. Next on his second output FSK 35 begins to form continuous control signal of the same duration and at the same time, at its third output generates a control signal by which the right of forming a continuous control signal, the control signal on the third output 35 FCC disappears.

The first trigger 35-2 is designed to start strobing generator 35-3 when receiving at its input signal station numbers (always starts from one) is implemented on the basis of typical schemes asynchronous RS-flip-flops [2] (p. 163-176, Fig. 10.1, 10.4, 10.10).

Strobing generator 35-3 is designed to generate a sequence of discrete pulses ("0" and "1") with the given parameters (amplitude, frequency, pulse duration) that functions as a control of a discrete signal, and the sequence of clock pulses. Is implemented on the basis of known schemes strobing generators [3] (page 116, Fig. 8.22).

The first frequency divider 35-4 is designed to generate at its output the signal through a time equal to the duration of the signal numbers of the mobile station. Is implemented on the basis of known schemes of frequency dividers [2] (page 208. . . 211, rice. 11.3, 11.5, 11.9), [4] (page 56, Fig. 44) [9] (p. 112, Fig. 5.54).

The second trigger 35-5 is designed to generate the enable signal of the first element And 35-1 upon receipt of the signal from the output of the first divider through an unlocked elementmajade its output signal over time, equal to the duration of the discrete control signal is implemented as a first divider 35-4.

In the composition of the two circuits includes a generator of continuous signals, for example, a sawtooth or triangular form [5] (p. 243. . . 267, rice. 10.9, 10.15, 11.5, 11.6, 11.7, 11.8, 11.9, 11.11, 11.13, 11.16) and electronic key [6] (page 162, 163 rice. 5.2, 5.3), [7] (p. 306, Fig. 14.3). In the circuit of Fig. 6A generator generates the signal continuously, at the entrance he only appears in the presence of a control signal to the corresponding input of the electronic key. In the circuit of Fig. 6b when receiving the control signal, the electronic key switches the power to the circuit of the generator. As a result, it is run and its output begins to form continuous control signal. In both circuits the power source not shown.

Is this the same as the first and second divisors of the La generation enable signal transmitter 25 in the radiation mode continuous FM signal, oscillator start-up 35-7, as well as control elements And 35 10 and 11. Is implemented on the basis of typical schemes asynchronous RS-flip-flops.

The imaging unit 15 is designed to deliver a start signal breathalyser block. By the same signal on BM 17. Formation start signal is at input f 15 code non-controlled mobile station output PSNS 12 (always starts with "1") after the time required for the complete reception rooms mobile station. Structural electrical circuit shown in Fig. 4. The circuit composition comprises: first and second triggers 15-1, 15-4 (implemented on the basis of typical schemes asynchronous RS-flip-flops): strobing generator 15-2 (implemented on the basis of typical schemes [3] (page 116, Fig. 8.22); the frequency divider 15-3 (implemented on the basis of typical schemes [2] , page 208. . . 211, Fig. 11.3, 11.5, 11.9).

The operation of the circuit (see Fig. 10). When input f 35 rooms mobile station trigger 15.1 translated in one state. Start the generator 15.2, the pulses from the output of which is coming to the divider 15.3. The signal at the output of the divider 15.3 immediately is conducted in one state and the output f 15 you receive a start signal. When it arrives at the other input f 15 reset signal from the corresponding output WB 16 (appears after the time allowed for the control of frequency deviation) he goes to the initial state (triggers and counter are set to zero).

Timing block (WB) 16 is designed to generate the third output signals run BI 18 before receipt by him of the control of discrete and continuous signals, respectively; for the formation of the (second exit) stop signal (reset) B 18 f 15 after the end of the measuring cycle deviation (over time equal to the duration of the control signals); for the formation of the (first output) signal, used to run AB 19 and unlock BS 1 20, BS 21 and BCL 23 in the end of both discrete and continuous control signals. Start WB 16 by means of a signal f 15.

Structural electrical circuit WB 16 shown in Fig. 5. It includes the first one-shot 16-1 (implemented on the basis of typical schemes [2] (page 167, Fig. 14.6) the first trigger 16-2 (implemented on the basis of typical schemes asynchronous RS-flip-flops), strobing generator 16-3 (implemented on the basis of typical schemes strobing generators [3] (page 116, Fig. 8.22); divisor often what is, for example, on the basis of typical schemes OR schemes delay [2] (page 266. . . 267, Fig. 14.4); element OR sheet 16-6 [1] (page 46, Fig. 1.27 C); element And 16-7; a frequency divider by two 16-8 (implemented on the basis of typical schemes counters [2] (page 208. . . 211, rice. 11.3, 11.5, 11.9) [3] (page 56, Fig. 44); the second trigger 16.9 (implemented on the basis of typical schemes asynchronous RS-flip-flops), the second one-shot 16-10 (implemented on the basis of typical schemes of odnovorov [2] (p. 167, Fig. 14.6).

Block work (see also Fig. 11).

In the initial state triggers 16-2 and 16-9, dividers 16-4 and 16-8 zeroed, adenovirally 16-1, 16-10 and strobing generator 16-3 in the original, ready to work, the element And 16-7 unlocked. When receiving a start signal from f 15 the one-shot 16-1 generates a pulse signal which comes through the element OR sheet 16-6 and unlocked the item And 16-7 at the third exit WB 16 and is the first start signal B 18. At the same time the trigger 16-2 is translated in one state that leads to the start strobing generator 16-3, the output of which is beginning to take shape a sequence of pulses, which are supplied to the divider 16-4. A pulse signal at the output of the divider 16-4 appears after a time equal to the duration of the control signal, and is supplied to the first in the ratio of fission TOAffairs= 2 and, in addition, through delay element 16-5, element OR sheet 16-6 and unlocked the item And 16-7 at the third exit WB 16 (is the second start signal BI 18). When it appears on the second output WB 16 a similar signal on the first output WB 165 disappears. After a time equal to the duration of the control signal, the output of the divider 16-4 newly formed pulse signal, which is supplied to the first output WB 16 and the second start signal AB 19. Also this signal is applied to the frequency divider 16-8 (has a division ratio TOAffairs= 2), the output of which a signal is generated, by which the trigger 16-9 translated in one state. As a result, the element And 16-7 blocked, thus excluding the signal from the divider 16-4 on the third exit WB 16. At the same time the signal from the trigger 16-9 the one-shot 16-10 generates a pulse signal, which is supplied to the second output WB 16 and serves to bring in the original f 15 and stop BI 18. Also the signal from the one-shot 16-10 WB 16 moves to the initial state (reset triggers 16-2 and 16-9, frequency dividers 16-4 and 16-8, unlocked the item And 16-7, strobing generator 16-3 ceases to generate a sequence of pulses).

Unit 17 commuter is in the presence of the control signal, coming from the shaper 15. Is implemented on the basis of known schemes [6] (p. 162, 163, Fig. 5.2, 5.3, 5.9).

Block 18 dimension (B) is designed to measure the maximum and minimum frequencies of the received control signals (Fmaxand Fmin). Work BI 18 is initiated by the start signal is received WB 16 at the time you start taking control of a discrete signal. The second start signal is supplied also with WB 16 at the time you start taking control of a continuous signal. When this BI 18 is reset and starts a new measuring cycle. After measurements are completed Fmaxand Fminfor both discrete and continuous signals, the stop 18 BI signal with the second output VB 6, which is formed in the end of the reception control continuous signal.

An embodiment of the BI 18 shown in Fig. 7. The unit is known device for measuring the frequency deviation (see ed. St. USSR N 1298676). The circuit composition includes shaper (f) 18-1; digital frequency detector (CCD) 18-2, the first and second blocks 18-3, 18-4 define the boundary frequency (BOGC), delay element (33) sheet 18-5, block 18-6 management (BU), the element OR 18-18. Each of BGC 18-3 and 18-4 in its membership include registryeasy.com [3] (page 116, Fig. 8.22), key (KL) 18-14, the divider 18-15 frequency (DF), the element OR 18-16, trigger 18-17.

BI 18 operates as follows.

In the initial state registers 18-7 and 18-8, triggers 18-10 both BOGS 18-3 and 18-4 zeroed. Triggers 18-12, 18-17 and QH 18-15, BU 18-6 zeroed. SG 18-13 in the original, ready to work. When it arrives at the second input of the BI 18 start signal (comes in the moment you start taking control of discrete signal) is reset through the OR element 18-18 register 18-7 and 18-8 first and second BOGC 18-3 and 18-4. By the same signal triggers 18-12 and 18-17 translated in one state, resulting in the unlocked key 18-14 and runs SG 18-13, which begins to form at its output a sequence of clock pulses. At the input of the shaper 18-1 receives control discrete outputs of the linear reception path RPU. F 18-1 generates short pulses, with the frequency of the input FM signal. Output CCD 18-2 after each pulse is updated code number, which characterizes the instantaneous frequency control FM signal, which comes in BOGS 18-3 and 18-4.

BOGC 18-3 meant to indicate the maximum number, works as follows.

Each pulse f 18-1, zaderzhany is, recorded in R 18-7, with the number recorded in R 18-8 using a digital comparator 18-9. If A>, then the output of comparator 18-9 a signal translating trigger 18-10 in one state. In the clock pulse received from BU 18-6 through the element And 18-11 on the clock inputs of P 18-7 and 18-8, overwrites number of R 18-7 in R 18-8. If AB, then the trigger 18-10 not tipped and R 18-8 retains the same number, i.e. P 18-8 is always the largest number of sequence numbers.

BOGC 18-4 run in parallel in a similar manner, only the comparator 18-9 it performs the function of AB, so register 18-8 is the smallest number of sequence numbers.

BOO 18-6 generates pulses for BOGS. The clock pulses from the output of the SG 18-13 through unlocked the key 18-14 come on QH 18-15 with a given division factor. When the output signal QH 18-15 trigger 18-17 through the element OR 18-16 set to zero. Key 18-14 blocked. In one state the trigger 18-18 transferred detainees in EZ sheet 18-5 signal with f 18-1. When receiving the second start signal (corresponds to the beginning of taking control of a continuous signal) work B 18 repeats. Upon entering the third t OR 18-18 is reset register 18-7 and 18-8.

The arithmetic unit (AU) 19 is designed to calculate the value of deviation of the frequency control digital and analog signals. An embodiment of the AB 19 presented at the FGI. 8. The circuit composition includes transducers direct code additional code (PAP) 19-1 and 19-2 is realized on the basis of known schemes converters [9] (page 123. . . 125, Fig. 5.86); scheme 19-3 subtraction (SV), which is realized on the basis of known schemes subtraction of binary numbers [8] (pages 82,83, Fig. 4.33); scheme 19-4 delay (Sz), which is realized on the basis of the elements OR with the combined inputs of or known delay circuits [2] (pages 266, 267, Fig. 14.5); Converter 19-5 additional code direct code (RAP), which is realized on the basis of known schemes converters [9] (page 123. . . 125, Fig. 5.86); keys 19-6 (implemented based on the model elements).

Work unit. For informational inputs AB 19 receives the binary codes corresponding to Fmaxand FminBI 18. In TTD 19-1, 19-2 they are converted into additional codes and arrive in ST. 19-3, the output of which is formed an additional result code, which is converted to direct the code in the RAP sheet 18-5 and goes to the keys 19-6. Unlock the keys on the control signal received from the WB 16 in the end of blokirovki keys) is not less operating time ACC ST. and RAP). At the time of occurrence of the pulse signal to the control inputs of the keys 19-6 data on the value of F is coming to the exit AB 19. Also instead of TTD 19-1, 19-2, ST 19-3 and RAP 19-5 can be used known ST [2] (page 139, Fig. 9.15 (a).

First, second and third blocks 20, 21 and 22 are designed to perform a comparison of the measured values of FmaxFminand F for the control of discrete and continuous control signals with their reference values entered in advance. All blocks are of the same type. An embodiment of the BS 20 is shown in Fig. 9. The circuit composition includes memory registers DD 20-1 and 20-2 (implemented on the basis of known schemes [2] , page 238, 239, Fig. 12.1, table. 12.1 and 12.2); elements OR DD 20-3; asynchronous counter on two digits DD 20-4 (implemented on the basis of known schemes counters [9] , page 98, 99, Fig. 5.15, 5.16); the one-shot DD 20-5 [2] (page 267, Fig. 14.6); comparison circuit DD 20.6 (implemented on the basis of known schemes [9] , page 117, Fig. 5.68).

The operation of the circuit. In the initial state in case DD 20-1 recorded maximum reference value of the frequency FmaxEOLfor discrete control signal, and in case DD 20-2 - FmaxENfor continuous control signal. Outputs Registrar outputs of the counter DD 20-4, which in the initial state reset. The recording and zeroing of information in registers DD 20-1 and 20-2 are produced by external control signals. When it arrives at the third entrance of BS 21 pulse signal from the first output WB 16 (corresponds to the end of the control discrete signal) at the output Q schetchik DD 20-4 you receive the low level signal, which leads to the unlocking of the outputs of the register DD 20-1. Data Fmaxedgo through the elements OR DD 20-3 at the entrances To the schema In schema comparison DD 20-6, the inputs And which receives data Fmaxdfrom BI 18. On one of the outputs of the comparison circuit DD 20-6 receive a signal depending on, what is the ratio between Fmaxedand Fmaxd(A>b or a= b or A<). When it arrives at the third entrance of BS 21 of the second pulse signal from the first output WB 16 (corresponds to the end of the continuous control signal) at the output Q 2 counter DD 20-4 you receive the low level signal, and the output Q1 is a high signal, which leads to blocking of the output register DD 20-2. Data FmaxENarrives at the inputs of the comparison circuit, the inputs And which receives data FmaxnBI 18. The results of the comparison appear on the output is. the Hema is translated to its original state.

The first and second blocks 23 and 24 keys (BCL) intended for commutation respectively to the outputs 18 BI, BS 21 outputs BR 13 and the external data bus in the presence of the control signal from the first output WB 16 and outputs AB 19 and BS 22 outputs BR 13 and the external data bus in the presence of the control signal on the control output AB 19. In the simplest case, are implemented on the model elements And the same inputs which are combined to form the control input, and the other (paired) inputs are information.

The transmitter 2 is typical and has a manipulation input discrete data, modulation input voice data (analog signal) and a control input for switching the transmitter from mode of transmission of discrete signals in the transmission mode continuous signals (see for example [10] , page 20, Fig. 1).

The remaining blocks are the blocks of the prototype, perform the same functions and are implemented similarly.

The device operates as follows.

In the initial state at the stationary station, the second imaging unit 6 of the control signal outputs to the control input of the second controlled attenuator 4 signal con tract of radio 2 is disconnected from the measuring input unit 18 of the measurement. Ramazashvili block 16, the measurement unit 18, the arithmetic unit 19, the first and second formers 15 and 23 in the source, ready to work, block 24 keys blackiron. At the mobile station, the driver 35 of the control signal in the source, ready to work, this triggers 35-2, 35-5, 35-9 and frequency dividers 35-4, 35-6, 35-8 zeroed, strobing generator 35-2 and the generator 35-7 sawtooth voltage source, ready to work. In the first, second and third blocks 20, 21 and 22 compare the data entered on valid interval values, respectively, the maximum and minimum values of the frequency control discrete FmaxedFminedand continuous FmaxENFminENsignals and data valid interval values of frequency deviation control of discrete and continuous signals FdedFdEN. Triggers 15-1 and 15-4 driver 15, and a divider 15-2 frequency zeroed, strobing generator 15-2 in the original, ready to work. Triggers 16-2, 16-9 and dividers 16-4, 16-8 frequency breathalyser unit 16 is reset to zero, and strobing generator 16-3 and adenovirally 16-1 and 16-10 in the original, ready to work.

When issuing a control signal to the driver 34 teams semoga radio transmitter 26, controlled by the meter 31 to the power level. If the power level at the output of the radio transmitter 26 corresponds to the norm, then the output of the meter 31 to the power level signal is formed, on which the imaging unit 34 start command generates a command signal about the health of the transmitter 26. If the output power of the transmitter 26 is below normal, the driver 34 start command generates a command signal malfunction. The signal containing information about the health of the transmitter 26, the output of the shaper 34 run through the element OR 33 is fed to the modulation input of the transmitter 26 and radiated. This signal of the mobile station is received and detected by the radio receiver 2 fixed station, is highlighted by the receiver 10 teams, and the control transmitter 26 is fixed in block 13 of the Desk. After that, the control unit 9 are formed team, which includes the imaging unit 8 of the control signal, and the power command generator 8 also postupdate on block 14 signal station numbers and the first imaging unit 3 control signal, and after a time delay fCdetermined by the delay element 7, turns on the second FD is and which is modulated by the control signal. The output voltage of the first driver 5 control signal linearly increases, this decreases the attenuation of the first controlled attenuator 3, and thus gradually increases the size of the emitted stationary power station. The control signal is received by the receiver 25 of the mobile station, the receiver 28 of the control signals, and upon reaching the input signal level sufficient to trigger the threshold of the block 30 at the output of the latter, and hence the output element And 29, a signal that includes the imaging unit 32 signal station numbers. The transmitter 26 is placed into the transmit mode number of the mobile station.

After the launch of the first imaging unit 5 of the control signal after a time determined by the delay element 7, starts the second imaging unit 6 of the control signal. Time tCwas supposed to equal the amount of time required by the mobile station to switch from the receive mode to the transmit mode and the operation of the receiver 12 signal station numbers. The output voltage of the second imaging unit 6 of the control signal adjusts the attenuation of the second controlled attenuator 4, i.e., the change ratio of the transmission signal from the mobile station measures taken at the stationary station and decoded by the receiver 12 signal station numbers in this transition value of the second controlled attenuator 4, which for proper transmitter 26 corresponds to the signal level at the input of the radio receiver 2 below threshold threshold unit 11. In this case, the block 13 registration records the condition of the radio receiver 25 and the check number of the mobile station. If the sensitivity of the radio receiver 25 is below normal, the tripping threshold of the block 20 is at a higher power level at the output of the first controlled attenuator 3, i.e., at a later point in time. The attenuation of the second controlled attenuator 4 in this case is smaller and decoding non mobile station at the output of the threshold unit 11, a signal is generated indicating a malfunction of the monitored receiver 25, which is fixed in block 13 of the Desk. In addition, room controlled at this time of the mobile station from the output of the receiver 12 signal station numbers entered in block 14 of the signal station numbers, where it is stored.

Simultaneously with the operation of the shaper 32 number signal of the mobile station (the number always starts with a single character) starts the imaging unit 35 of the control signal, which after the end of the control signal begins to form on the first NWO is of a given length), which through the element OR 33 is fed to the modulation input of the transmitter 26, which is intended to enter discrete information. In the imaging unit 35 of the control signal in the trigger 35-2 record unit and the signal with its inverted output started strobing generator 35-3, the output of which begins to form a discrete sequence of symbols. The overflow of the first frequency divider 35-4 will happen at the end of the signal transmission station numbers with shaper 32. The overflow signal of the second trigger 35-5 translated in one state, the first element And 35-1 is unlocked and its output appears in the control sequence of binary symbols that come through the element OR 33 to the modulation input of the transmitter, designed for discrete input information.

Formed simultaneously sequence with the first element And 35-1 through the first output driver 35 is fed to the input of the second divider 35-6 frequency, which fills up in a time equal to the specified duration of the control sequence of binary symbols. The overflow signal resets the second trigger 35-5, and the third trigger 35-9 recorded unit. The first and Valinoti begin in the third frequency divider. Simultaneously start the signal generator 35-7, which begins to form continuous control signal, the amplitude of which varies, for example, a sawtooth or triangular law. Moreover, the minimum and maximum values of the amplitude of the analog control signal are respectively the minimum and maximum values of the real analog information signals input to the transmitter 26 in the conduct of the radio in operation.

Control continuous signal through the second output driver 35 of the control signal fed to the modulation input of the transmitter 26 that is designed to input analog data. At the same time on the third output of the shaper 35 receive a control signal, which converts the radio transmitter 25 in the mode of transmission of analog information. Over time, equal to the specified duration continuous control signal, the third divider 35-8 frequency of overflows, resulting triggers 35-2, 35-5, 35-9 and dividers 35-4, 35-6, 35-8 are set to zero, the first and second elements And 35-1 and 35-10 blocked, and the third element And 35-11 unlocked. Shaper 35 enters the initial state, the signals on its outputs are not available. Radio is controlled station (always starts with a single character, for example 1011) starts the imaging unit 15, through which the time required for full admission code non-controlled station, generates at its output a start signal. When this trigger 15-1 is translated in one state, resulting starts strobing generator 15-2, the output of which begins to form a sequence of pulses input to the divider 15-3 frequency. Output divider 15-3 through time equal to the duration of the signal numbers of the mobile station, receive a pulse signal. As a result, the trigger 15-4 goes in one state and its output is formed by a start signal. The consequence of this is starting breathalyser block 16 and block 18 measurement and the output of the linear reception path through the switching block 17 is connected to the information input blaa 18 measurements.

When entering timing unit 16 of the start signal from the imaging unit 15 and the one-shot 16-1 generates a pulse signal, which through the element OR sheet 16-6 and 16-7 supplied to the third output, and is the first start signal unit 18 measurements. At the same time the trigger 16-2 is translated in one state, starts strobing generator 16-3, the output of which begins the formation of the duration control-discrete signal, goes to the first output breathalyser block 16 and is the first start signal arithmetic unit 19. Also this signal is applied to the input of the divider 16-8 frequency having the division ratio TOAffairs= 2 and, in addition, through delay element 16-5, element OR sheet 16-6 and unlocked the item And 16-7 on the third exit breathalyser unit 16, the second start signal unit 18 measurements. At his appearance the same signal on the first output breathalyser unit 16 is lost. After a time equal to the duration of the continuous control signal at the output of the divider 16-4 frequency of the newly formed pulse signal, which is supplied to the first output breathalyser unit 16 and the second start signal arithmetic unit 19. Also this signal is applied to the divider 16-8 frequency with KAffairs= 2, the output of which is formed a high signal. Trigger 16-9 translated in one state. Element And 16-7 blocked, thus excluding the signal from the frequency divider 16-4 in the third output breathalyser block 16.

At the same time the signal from the trigger 16-9 the one-shot 16-10 generates a pulse signal, which is supplied to the second output breathalyser block 16 and serves on the th reset signal triggers 16-2 and 16-9, dividers 16-4 and 16-8 frequency, unlocked the item And 16-7, strobing generator 16-3 stops the formation of a sequence of pulses. Timing unit 16 moves to its original state.

Received by the radio receiver 2 control discrete outputs of the linear reception path is passed to the block 18 measurements. It defines the maximum Fmaxdand minimum Fmindthe frequency of the received control of a discrete signal, the measured nominal values are transmitted to the inputs of the first block 23 keys, respectively, to the inputs of the first and second blocks 20 and 21 compare, as well as in the arithmetic unit 19. After a time equal to the duration of the measuring cycle (equal to the time control of discrete signal), the timing unit 16 at its first output generates an enable signal on which the arithmetic unit 19 on the basis of those present at its data inputs data about the maximum and minimum values of frequency Fmaxdand Fmindcontrol of discrete signal computes its frequency deviation according to the formula Fdd= Fmaxd- Fmind. The value of the deviation FddmaxdFmaxdeFmindFmindeFddFdde), the output units 20, 21 and 22 are formed of single signals, and otherwise zero, which enter the corresponding inputs of the first block 23 keys. The enable signal also unlocked the first and second blocks 23 and 24 keys and data about the measured values of the maximum Fmaxdminimum Fmindfrequency discrete control signal, the frequency deviation Fddand the results of the tolerance control act in block 13 of the Desk. After that, the enable signal at the output of arithmetic block disappears, the first and second blocks 23 and 24 keys, and the first, second and third blocks 20, 21 and 22 compare blocked. On the third output breathalyser unit 16, a signal is generated, by which the block 18 measurement is translated to its original state. Next to the input unit 18 measurement output line receiving channel of the radio receiver 2 through the switching unit 17 receives a control continuous sigalotti, measured denominations which also receives information on the inputs of the second unit 24 keys, respectively, to the inputs of the first and second blocks 20 and 21 compare, as well as in the arithmetic unit 19.

After a time equal to the duration of the measurement cycle timing unit 16 at its first output generates the enable signal, then the device works in the same way as in the case of discrete control signal. The only difference lies in the fact that tolerance control was obtained p results (FmaxnFminnFdn= Fmaxn- Fminnis a valid reference intervals corresponding to the continuous control signal, (FmaxneFminneFdn), which is defined as the second enable signal received at the control inputs of the blocks 20, 21 and 22 compare. After reception of results of the control unit 13 of the Desk on the second output breathalyser unit 16, a signal is generated translation in the initial state, in which the imaging unit 15 is reset, with reset triggers 15-1, 15-4, and a divider 15-3, and the switching block 17 and block 18 dimensions are blocked. Output line receiving channel radiopost completed. So the proposed device operates under control with the mobile station control on the initiative of the mobile station).

When the control from the fixed station device operates as follows.

In block 14 of the signal station numbers entered (through the third input) conditional number of the station, the control which must be done. Unit 14 signal station numbers controls the presence of a signal at the output of the imaging unit 8 of the control signal (sign SK). In the absence of Tikal control ( SK= 0) from the output of block 14 signal station numbers to the input of the transmitter 1 receives a command for switching on the radiation (VR) and introduces a number signal controlled station (SN). The number signal of the controlled station to the input of the transmitter 1 through the first controlled attenuator 3 and the appropriate antenna device to the input of the radio receiver 23 of the mobile station, is detected and supplied to the receiver 24 number signal station, where comparing the received identification numbers with the number assigned to the mobile station. If the numbers match, then the output of receiver 24 signal station numbers formed team, which as with the control with the mobile station.

In the case of cycle control (SK 0) unit 14 signal station numbers through time tCimplementing a new control loop characteristic SK. If SK = 0, the device operates similarly. The delay time is chosen equal to the maximum cycle time control of one of the rolling object.

Technical appraisal and economic benefits of the proposed device in comparison with the prototype consists in extending its functionality by implementing the possibility of remote monitoring of frequency deviation of the radio stations of mobile objects using frequency-modulated signals and operating in the mode of transmission of discrete information, and transfer mode continuous analog information. This identifies the minimum and maximum values of the frequency modulated (manipulated) signal. In addition, the possibility of comparing the upper and lower cutoff frequencies, and the frequency deviation with a predetermined (reference) values for controlled mobile stations with the issuance of data on the output of monitored parameters outside of the established intervals. This ultimately allows real-time assessment of the judge is to use and to implement a more objective planning of routine maintenance. Therefore, the proposed device allows to reduce the total time for an inspection stations moving objects, as well as to increase the objectivity of control, because in addition to monitoring of energy parameters of the transmitter and the sensitivity of the radio is controlled by the frequency characteristics of the radio stations of mobile objects, in which there are certain tolerances defined by the requirements of the EMC.
