The invention relates to techniques for radio communication and is intended for use in digital radio transmitting devices of high reliability.

A device to enable a backup radio transmitting circuit containing the master oscillator and two amplifier channel, of which one primary, backup generator, high-frequency outputs which through the antenna switch is connected with the antenna. In the device the signal is fed to both of the tract. If some time after the receipt of the input signal at the output of the primary path does not appear, then turn on the standby path, and the main is turned off (see A. S. N 35456, NRB, MKI 4 H 04 7/005, 1984). The main disadvantage of this device is the availability of high frequency contact switch designed for switching amplification paths that, at high power leads to reduced device reliability. To increase the reliability of the switches when switching from the primary path to the backup off the high voltage, however, this leads to an increase of the time is, MCI H 04 1/04, 1981) and device backup transmitter (Application N 23394, Japan, MKI H 04 1/74, 1985). The closest number of similar features is the device backup transmitter containing the pathogen, the primary and backup power amplifiers, antenna, contactless antenna switch, two delay lines high frequency signal, one output of each power amplifier, the power supply for each power amplifier with power switches, sensors, control current in the circuits of power amplifiers, analyzers-state power amplifiers and a control unit performing production control commands switching amplifiers power from the primary to the backup and the antenna connection to an active amplifier.

This device will accept as a prototype.

The disadvantages of the prototype are:

1. Large power loss in the high frequency channel radio transmitter. This is because, firstly, the high frequency power signal back to the amplifier (in good condition both amplifiers) is spent in useless ballast load, and, secondly, greater losses contribute to the delay line in the form of segments to the ballast load). When the velocity of propagation of electromagnetic waves in the high frequency cable, equal to 200,000 km/s, to provide a delay for the high-frequency signal even on 1 with will need the segment cable length 200000 km Attenuation introduced in this segment of the cable will be approximately 105- 106dB.

2. The introduction of delay lines in both tract in principle cannot exclude loss of information when switching amplifiers, because in the presence of delay lines in both paths there is no relative delay of the signal in one path over another. Therefore, when switching amplifiers, the information is lost.

3. The reliability of the device is low due to the presence of a single agent, because the radio when working both amplifiers, but faulty exciter fails to work. In addition, as in the case of the good working order of the two amplifiers they (both) are included, the time between failures becomes twice smaller than under the sequential switching amplifiers.

switches 27, 29 and 28, 30 for inclusion (switch) delay line information signal 26 in the path (first or second), which is the backup.

The device operates as follows.

Any tract (the first or the use of manual switch 35 of the control unit 8. In the position of the switch 35 "O. 1" ("On. Tr") provides power to the exciter and power amplifier of the first path and connect to the antenna, in this case, the first path is working, the second backup. In position "O.2" ("Incl. Tr") - provides power to the exciter and power amplifier of the second path, the second path is working, and the first backup. With the switch 35 in the middle position (Off.) power to the exciters and amplifiers of both paths is not available, the transmitter is turned off.

Suppose that, initially as a working radio selected first, and as a backup second. For this purpose, the switch 35 is set to the position "O. 1" ("On. Tr."). In this case, a constant voltage from a voltage source 39 through the closed contacts I" and "O. 1" switch 35 is supplied to the third control output ("O. 3) control unit 8 and further to the control inputs of the switches 27 and 29, which connect the first output ("O. 1") of the information signal splitter 25 to the input of the exciter 1 of the first path through the circuit: O. 1 coupler, the information signal 25, the signal input of the switch 27, the first output (O. 1) the fourth control output (O.4) the control unit 8, the voltage from voltage source 39 is not available, on the control inputs of the switches 28 and 30 is missing. The information signal with the Output. 2 splitter 25 through the closed contacts I" and "O. 2" switch 28, the delay line 26, the closed contacts Ref.2" and "O." the switch 30 is fed to the input of the exciter 17 of the second tract. Thus, through the corresponding connection contacts of the switches 27, 29 and 28, 30 information signal is fed to the input of the exciter 1 of the first path (which is selected as the desktop) without delay, and the input of the exciter 17 of the second path (which in this case is redundant) with a delay.

In addition, a constant voltage from the Output.1" manual switch 35 of the control unit 8 is supplied to the control inputs of switches and 36.1 36.5, causing the contacts of these switches are closed. Through the closed contacts of switch 36.1 voltage corresponding to a logical unit, is fed to the first input of logic element And 32.3. The surge that occurred in the switch 36.1, will cause the charge current of the capacitor 37.1 through resistor 38.1. Created by this current the voltage from the resistor 38.1 is supplied to the second input of logic element OR 33.1, resulting in its output appears H3. Since both inputs of the element And 32.3 present voltage corresponding to a logical unit, its output will be a voltage of the logic unit, through which the first control output (O.1) control unit 8 will be submitted to the control inputs of the power switch 19 of the pathogen first tract, the power switch 11 power amplifier of the first path and the antenna switch 6. These switches provide the power of the exciter 1 and the amplifier 3 of the first circuit and the antenna connection 5 to the output of the amplifier 3, that is, to the output of the first (working) radio.

Informational digital signal fed to the input of the exciter 1, performs modulation in him a high-frequency signal, which is amplified in the amplifier 3 and with its output through the antenna switch 6 is supplied to the antenna 5 and the antenna radiates into space.

In the case of a defective condition of the exciter 1 and the amplifier 3 outputs sensors control power 21 and 13, and from the outputs of the analyzers condition 23 and 15 for informational inputs Ref.5, Ref.6, Bx.1 and Ref.2 control unit 8 receives signals a logical zero, which are fed to the inputs of the elements OR NOT 31.1 and 31.3. On jihovychod which the signal of the logic unit will be served at the first input element OR 33.1. The signal of the logical unit with the output element OR 33.1 is supplied to the second input element And 32.3, at the first input from the voltage source 39 through the closed contacts Ref. - O. 1 (Incl. Tr) manual switch 35, closed contacts controlled switch 36.1 is energized, the corresponding logical unit. Output element And 32.3 be the voltage of the logic unit, through which the first control output (O. 1) control unit 8 is supplied to the control inputs of the power switches 19 and 11 of the exciter and amplifier of the first path, and the control input of the antenna switch 6, providing the first path and connect to the antenna.

After a certain period of time the capacitor 37.1 charged, the current in the circuit to charge a capacitor 37.1, resistor 38.1) will cease, resulting in the voltage at the second input element OR 33.1 be appropriate logical zero. As in the case of a working state of the first path at the first input of logic element OR 33.1 will be a voltage corresponding to a logical unit, its output will be a voltage corresponding to a logical unit that provides the first tract.

This vosburg they are not served. It is provided as follows. First, the signal of the logical unit with the output element And 32.3 is input to the element is NOT 34.1, the output of which a signal of logical zero through the closed contacts of switch 36.5 fed to the control input of switch 36.4, at which its contacts are open. Secondly, be open and the switch contacts 36.3, because its control input is not supplied with voltage from a voltage source 39.

In case of failure of the first (working) tract because of the "short circuit" or "cliff" at the output of the sensor current control 21 or 13, or analyzer 23 or 15, or the outputs of several of these blocks first (working) path, a signal will appear as a logical unit. At the output of the element OR NOT 31.1, either at the output of the element OR NOT 31.3, either at the outputs of both elements 31.1 and 31.3 appears a signal of logical zero. In any of these cases, the output element And 32.1 appears the signal is a logical zero, which will be available at the first input element OR 33.1. As to a second input element OR 33.1 a signal of logical zero (the voltage is zero), then the output element OR 33.1 appears the voltage (signal) corresponding to logical signal is a logical zero. This signal through the first control output (O. 1) control unit 8 will be transferred to the control inputs of the power switches 19, 11 exciter and power amplifier of the first path, and the control input of the antenna switch 6, which will result in a disconnected power from the exciter 1 and the amplifier 3 of the first path and the antenna switch 6 connects the antenna 5 to the output of the power amplifier 4, i.e. to the output of the second tract, which was as a backup.

Simultaneously, the signal of the logic zero from the output element And 32.3 fed to the input of the item 34.1, the output of which produces a signal of logical units, which through the closed contacts controlled switch 36.5 fed to the control input of switch 36.4, closing its contacts. The voltage from the source 39 of the control unit 8 through the closed contacts of switch 36.4 arrives at the first input element And 32.4 and provides a current flows to charge capacitor 37.2 through resistor 38.3. The voltage generated by this current in the resistor 38.3 corresponding logical unit, is fed to the second input element OR 33.2, causing its output signal to a logical unit, which is fed to the second input element 32 is itzá, its output will be generated signal of the logic unit, which via a second control output (O. 2) control unit 8 will be transferred to the control inputs of the switches 20 and 12, providing a power connection to the exciter 17 and the power amplifier 4 of the second path.

Informational digital signal with the second output (O. 2) splitter 25 through the closed contacts I" and "O.2" switch 28, the delay line 26, the closed contacts Ref.2" and "O." the switch 30 is fed to the input of the exciter 17 of the second tract. As to the input of the exciter 17 of the second path enters an information signal that is delayed relative to the information signal received at the input of the exciter 1 of the first tract, loss of information when switching the transmitter from the first (working) on the second (backup) the tract does not occur provided that the time delay provided by the delay line information signal 26 a few more time required for switching the transmitter from the first path to the second. To ensure tact promote digital information signal in the delay line 26 at its clock input from the clock input devices backup (connected to a clock output istochnikam, received at the input of the exciter 17, performs modulation frequency vibrations in it. These oscillations are amplified in the amplifier 4 through the antenna switch 6 is supplied to the antenna 5.

In case of failure of the second path when a faulty ground path must be provided power from the exciter 17 and the power amplifier 4 of the second tract and the denial of power to the exciter 1 and the amplifier 3 is defective the first tract.

This is done as follows.

Suppose that, initially, as work was included in the first path, that is, the switch 35 of the control unit 8 is set to O. 1 (Incl. Tr. ). As was shown above, when the failure of the first path signal of the logic zero from the output element And 32.3 turns off the power from the exciter 1 and the amplifier 3 of the first tract. When failure and the second path to the output element And 32.4 generate a signal of logical zero, which will remove power from the exciter 17 and the power amplifier 4 of the second tract. When this signal is the logical unit with the output element is NOT 34.2 arrives at the input of the control switch 36.6, the control input of which, the sun is about, the switch contacts 36.6 will be open, and the signal of the logical unit with the output element is NOT 34.2 is not received on the control input of the controlled switch 36.2 and its contacts will remain open. The switch contacts 36.1 closed, and the voltage corresponding to a logical unit from a voltage source 39, is fed to the first input element And 32.3. At the second input element And 32.3 be a voltage corresponding to a logical zero, since both inputs of the element OR 33.1 present voltage corresponding to a logical zero. For inclusion (defective) of the first path when the failure of the second path would need some time to open the switch contacts 36.1, to allow the capacitor 37.1 be discharged through resistor 38.2, and then to close the switch contacts 36.2, ensuring the flow of current to charge capacitor 37.1 through resistor 38.1 that you want to appear on the second input element OR 33.1 voltage corresponding to a logical unit. Since this is not the case, turn on the power on the failed first tract of the transmitter at the failure of the second tract is not going to happen. The power will be disconnected from both paths.

The logical signals of VARIA".

To turn off (power) of the radio should switch 35 is set to the position "Off".

Evaluation of the obtained effect of the inventive device in comparison with the prototype will perform on three indicators: reliability, energy losses and loss of information when switching paths.

1. Denote by Rin- the probability of the good state of the pathogen and Pmind- the probability of the good state of the power amplifier. Believe events outages exciters and amplifiers are independent. The probability of the good state of the transmitter "prototype"

PCorr.FR.= Pin[1-(1-Pmind.1)(1-Pmind.2)].

The probability of the good state of the claimed device

PCorr.Appl.=1-(1-PB1Pmind1) (1-PB2Pum).

For example, suppose Pin=PB1=PB2=Pmind1= Pum=0,8.

Then

PCorr.FR.= 0,8[1-(1-0,8)(1-0,8)]=0,766,

PCorr.Appl.= 1-(1-0,8 0,8)(1-0,8 0,8) = 0,87.

Thus, the reliability of the claimed device is higher than the reliability of the device prototype.

In addition, because of the possibility bookeepers twice.

2. Due to the fact that the outputs of the amplifiers in the claimed device is connected directly to the input of the antenna switch and not through the delay line, as in the prototype, the energy costs of the claimed device are significantly lower compared to the prototype. In addition, the prototype power of a high frequency signal of the reserve tract spent on useless ballast load, declared in the same device backup path is turned off and therefore the energy (power) do not consume.

3. The inclusion of the claimed device one line delay of the information signal switching it every once in a tract, which is the backup, ensuring no data loss when switching transmitter with a working radio for backup. In the prototype, due to the presence of a non-switched delay lines in both paths, such losses are inevitable due to the same delay signals in both paths, and consequently, the lack of relative delay.
