The claimed device operates as follows.

At power-on the first installation the output of the initial installation 13.7 (Fig.2) a signal is applied to logic "1" which is fed to the fourth and fifth mounting inverted inputs respectively D-flip-flop 13.11 and JK-flip-flop 13.10. On the second installation unit output initial installation 13.7 will be short-term signal of logical "0" (defined ASU is 13.62and on the third and fourth mounting inverted inputs and the second and third clock inputs, respectively, of the D-flip-flop 13.11 and JK-flip-flop 13.10. As a result, the N outputs of the counters 13.61and 13.62will be a signal of logical "0" and they will be ready by the first counting inputs and outputs of the JK-flip-flop 13.10 and D-flip-flop 13.11 be a signal of logical "1" and the triggers will be ready to work on the control inputs. Thus, the first, second, third and fourth control outputs of the control unit 13 is a signal of logical "1".

The logical signal "1" from the first control output of the control unit 13 is supplied to the third control inputs of the switches 101, 102and 103.

The order of operation of the switch 10 (Fig.3) can be seen on the example of the operation of the switch 101as the work of the other switches 102, 103and 104similar.

At the first input of the power splitter 10.1.1 goes high frequency oscillation with a first information input of the switch 101that is split and supplied to its first and second outputs, and a high-frequency oscillation on the second output perfectly in phase from the high-frequency vibrations on the ground Jonny switch input 101goes unmatched high-frequency oscillation, which is the result of inconsistent elements of the attenuator 10.1.1. High frequency oscillation from the first output of the power splitter 10.1.1 is fed to the first input of the adder power 10.1.3, and from the second output of the power splitter 10.1.1 served on the first information input of the control phase shifter 10.1.2. As to the second control input of the controlled phase shifter 10.1.2 with the third control input of the switch 101the signal of logic "1" high-frequency oscillation at the output does not change in phase and fed to the second input of the adder power 10.1.3. High-frequency oscillations received by the first and second inputs of the adder power 10.1.3, relative to its first output will be out of phase and cancel each other, and relative to the second output will be in phase and will go to the second output of the switch 101.

If the second control input of the controlled phase shifter 10.1.2 signal of logical "0", the high frequency oscillation at the output will change in phase relative to high-frequency fluctuations of the input 180o. Thus, high-frequency vibrations received at the first Hod switch 101and regarding the second output will be out of phase and cancel each other out.

Thus, during normal operation, a high frequency oscillation applied to the first or second information input of the switch 10, is switched accordingly to its second or first output. When a failure of the primary or the backup transmission paths 2 high frequency oscillation applied to the first or second information input of the switch 10, is switched respectively at its first or second output.

Signals of logical "1" from the second and third control output of the control unit 13 serves on the second control inputs of the respective power switches 6. This signal is to allow the connection of power supply units 5 through the power switches 6 and sensors control power 8 respectively to the primary and backup transmission paths 2.

Thus, the device backup transmitter with dynamic delay is given to the original state and ready to work.

Consider the operation of the device backup transmitter with dynamic delay in the normal state.

High frequency oscillation output of the exciter 1 is fed to the first input of Delhi oscillation, which is compensated in the ballast load 111. High frequency oscillation, divided in half between the first and second outputs of the power splitter 71goes to the first information input of the primary and backup transmission path 2. Because the primary and backup transmission paths 2 no failures of type short circuit, the second control outputs sensors control power 8 is a signal of logical "0" which is supplied to the third and fourth control inputs of the control unit 13. Next, high-frequency oscillation outputs of the primary and backup transmission path 2 is fed to the inputs of signal converters 3, which is converted to the form required by the control unit 13 to analyze the health of the primary and backup transmission paths 2 on the failure type, breakage, and served on the first and second control inputs of the control unit 13. At the same time high-frequency oscillation output of the main transmitting tract 21served on a first information input of the switch 104where it the second information input appears inconsistent high-frequency oscillation, which is compensated in the ballast load 115. The switch 104computerwatermark 91. Thus, during normal operation of the device backup transmitter with dynamic delay no delay between the high-frequency oscillations from the output of the main transmitting tract 21to the antenna 4. Next, high-frequency oscillation is fed to the first information input of the switch 101that similarly commutes on his second output.

High frequency oscillation output backup transmitting tract 22is fed to the input of the delay line 92. Delay high-frequency oscillations in the delay line 9 is calculated on the time needed by the control unit 13 on the performance analysis of the primary and backup transmission path 2 and the switching of the switches 10. From the output of the delay line 92high frequency oscillation is supplied to the first information input of the switch 102where it is switched to its second output. From the second output switch 102high frequency oscillation is supplied to the second input of the attenuator 72where it is split between its two outputs, and then compensated in equivalent antenna 12.

Thus, do not delay high-frequency oscillation only motirola on its first release and will be available from the antenna 4.

If the master or the backup transmission path 2 has failed short circuit, the second control output of one of the sensors control power 8 signal is logical "1" on the third or fourth control inputs of the control unit 13. If the master or the backup transmission paths 2 failure type open circuit, then output one of the signal transducers 3 will be constantly supplied sequence of zeros in the first or second control inputs of the control unit 13.

Consider the operation of the control unit 13 at the failure of the primary or backup transmitting circuits type 2 short circuit or open circuit.

If mainly the transmitting tract 21failure type short circuit or open circuit, in the first case, the logical signal "1" from the third control input of the control unit 13 will go to the second input element OR 13.92.

In the second case, the first control input of the control unit 13 a sequence of zeros will arrive at the input of the inverter 13.31and to the first input of the modulo two 13.5. As to the second control input of the control unit 13, and hence to the input of the inverter 13.32and the second input of the modulo two 13.5 comes in atora modulo two 13.5, in the result at its output, a signal will appear logical "1". This signal will go through the second input element OR 13.91at the first input element And 13.42on the second input of which is a logical signal "1" from the second installation unit output initial installation 13.7.

With the output element And 13.42the logical signal "1" is inverted in the inverter 13.33and the logical signal "0" is supplied to the first control input of D-flip-flop 13.11, turning it into a state of logical "0" output.

Simultaneously with the output element And 13.42the logical signal "1" is supplied to the first input element OR 13.91, thus ensuring the consistency of the logical signal "0" at the first control input of D-flip-flop 13.11 and, consequently, on the fourth control output of the control unit 13. This ensures stable operation of the control unit 13 when the coincidence of the sequence of zeros, describing the malfunction of the main transmitting tract1type the cliff and the information signal with the first and second control inputs. The logical signal "1" from the output of the modulo two 13.5 also fed to the input of one-shot 13.2 started it. The duration of the one-shot 13.2 wannago signal of logical "1" until when N the output will be a signal of logical "1". As the generator of clock pulses 13.1 constantly generates a clock pulse sequence to the first input element And 13.41then its output will appear synchronization sequence units coming on the second clock inputs of counters 13.6. As a result, the counters will count in the first counting inputs. As the first counting input of the counter 13.61will be constantly applied signal is a logical "1" output of inverter 13.31it will give account before the counter 13.62and its N outputs will appear a signal of logical "1" which will translate multiple-input element OR 13.81in the state of logical "1" output. This signal is logical "1" is received on the first input element OR 13.92. Thus, the control unit 13 is able to identify the failure of the main transmitter tract1failure type breakage.

Next, the operation of the control unit 13 to the failure of a main transmitting tract 21type a short circuit or break the same. The logical signal "1" from the output element OR 13.92is inverted by the inverter 13.34and on the second control output of the control unit 13 and the second control input of the JK-flip-flop 13.10, turning it into a state of logical "0". Thus, the first control output of the control unit 13 is a signal of logical "0" and the signal output will not show the signal "accident", as configured on the simultaneous failure of primary and backup transmission paths 2.

If back in the transmitting tract 22failure type short circuit or open circuit, in the first case, the logical signal "1" from the fourth control input of the control unit 13 will go to the second input element OR 13.93.

In the second case, the second control input of the control unit 13 a sequence of zeros will arrive at the input of the inverter 13.32and to the second input of the modulo two 13.5. Next, the operation of the control unit 13 is similar to the operation when a failure of the primary transmitting tract 21type of breakage. The difference lies in the fact that at first the counting input of the counter 13.62will be constantly applied signal is a logical "1" output of inverter 13.32and he will render account before the counter 13.61and to the first input element OR 13.93signal is logical "1". Thus, the control unit 13 is able to identify the failure of the backup transmitting tract 22when otkazatcia circuit or open circuit is identical. The logical signal "1" from the output element OR 13.93is inverted by the inverter 13.35and on the third control output of the control unit 13 is a signal of logical "0". Simultaneously, the logical signal "1" is supplied to the second input element And 13.43and on the first control input of the JK-flip-flop 13.10, leaving it in a state of logical "1". Thus, the first control output of the control unit 13 is a signal of logical "1" and the signal output will not show the signal "alarm".

If the primary and backup transmission paths 2 at the same time, there was a failure of type short circuit, the signals are logic "1" from the third and fourth control inputs of the control unit 13 will act on the second input elements OR 13.92and 13.93. Their output signals of logic "1" will appear on the first and second inputs of the element And 13.43and on the signal output control unit 13, a signal will appear "accident". Signals of logic "1" outputs of elements OR 13.93and 13.93inverted in inverters 13.34and 13.35, resulting in the second and third control outputs of the control unit 13 is a signal of logical "0", and the first control output is the inverted signal of the previous state is the failure of a main transmitting tract 21type a short circuit or break.

In the first case, the second control output of the control unit 13 is a signal of logical "0", which is a prohibiting signal to the power switch 61connection of power supply 51to the main transmitting tract 21, resulting in the power supply 51will be turned off by the power switch 61from a basic transmission path 21. Also on the first control output of the control unit 13 is a signal of logical "0", which is a control signal to the switches 101, 102and 103the switching frequency vibrations with their first information input at the first exit. The result will be switching from a basic transmission path 21to backup the transmit path 22and delayed high-frequency oscillation will be available from the antenna 4. Thus, when a failure of the primary transmitting tract 21type a short circuit at the time of switching from the primary transmitting tract 21to backup the transmit path 22data loss does not occur.

In the second case, the fourth control output of the control unit 13 is a signal of logical "0" which alarming input to the first output. In the resulting high-frequency oscillation is delayed in delay line1while the control unit 13 on the analysis of the functionality of the main transmitting tract 21and switching of the switches 101, 102and 103. Thus, the sequence of zeros from the output of the main transmitting tract 21not received in the antenna 4. Next, the operation of the device backup transmitter with dynamic delay is similar to the operation when a failure of the primary transmitting tract 21type a short circuit. Thus, when a failure of the primary transmitting tract 21type of breakage at the time of switching from the primary transmitting tract 21to backup the transmit path 22data loss does not occur.

Consider the operation of the device backup transmitter with dynamic delay due to bounce back the transmitting tract 22type a short circuit or break.

In the first case, the third control output of the control unit 13 is a signal of logical "0", which is a prohibiting signal to the power switch 62connection of power supply 52to backup the transmitting tract 22, the result of the and 22. On the first and fourth control outputs of the control unit 13 will remain a logical signal "1" and will be the main connection of the transmitting link 21to the antenna 4 without delay high-frequency oscillations. Thus, failure of backup transmitting tract 22type short circuit loss of information occurs.

In the second case, the fourth control output of the control unit 13 is a signal of logical "0", which is a control signal to the switch 104the switching frequency vibrations with its first data input to the first output. In the resulting high-frequency oscillation is delayed in delay line1while the control unit 13 on the analysis of health reserve the transmitting tract 22and switching of the switches 101, l02and 103. This is a dynamic inclusion of delay lines1. Next, the operation of the device backup transmitter with dynamic delay is similar failure backup transmitting tract 22type a short circuit. Thus, failure of backup transmitting tract 22type break loss of information not Paiania signals of logical "0" from the second and third control output of the control unit 13 will go on the power switches 6. Causing the power switches 6 will disable the power supply from 5 primary and backup transmission path 2, and the signal output control unit 13, a signal will appear "accident".

Thus, the analysis of the principle of operation of the inventive device backup transmitter with dynamic delay shows the obvious fact that along with saved possibilities for contactless switching out a failed radio transmitting circuit due to a short circuit or breakage without loss of information improves the timeliness of information transfer associated with dynamic switching delay lines at the failure of transmitting paths of type short circuit or breakage, and increased the reliability of its work associated with the unambiguous definition of unhealthy transmitting path when the failure type of breakage.
