The invention relates to radio engineering and is intended for use in communication systems when building a highly reliable, redundant communications systems.

The known device for controlling the switching of the moving allowance [1] and [2] provide control of switching a moving allowance. However, these devices provide backup radio controlled from external devices on a wire. Potentially them to the technical essence is a multichannel device for reservation stations [3], contains the main radio stations, control units, memory block codes setup, register, back-up radio with power electronic frequency tuning. However, this device allows for the backup of only one backup radio. In addition, this device provides the reservation stations in the same modes as a backup radio station when it is connected instead of the main, is only the operating frequency tuning.

The purpose of the invention is to enhance reliability of operation, expanding the scope and improving the efficiency of operators.

To do this in a multi-channel device for reserving radio stations containing the backup radio station that is connected in series with the power frequency, a decoder, a register, a memory block codes and settings for each channel main station connected through the control unit with the element OR the element, OR replaced by a control unit switching the moving spare memory block codes configuration is replaced by the block address rewriting and put the remote control stations, and outputs control panels via the bus commands uprate connected to the control inputs of the main and backup radio stations control outputs are connected to inputs of the control unit switching a moving allowance, the outputs of which are connected to second inputs of the block address rewriting, the second outputs of which are connected with inputs of survey control panels.

Improving the reliability of the device is ensured by a sliding redundancy of the main radio stations, multiple backup radio stations, which is achieved by introducing in the known device a few backup radio stations, a control unit switching a moving allowance and block address rewriting.

Extending the scope of application of the device is ensured by the possibility of rebuilding a backup radio in all modes of operation of the failed main radio stations due to forwarding commands on a connected radio with electronic reconstruction modes.

Improving the efficiency of operators is provided by the introduction in the known device control panels, which is the identity of the workplace, not a specific radio station. With these remotes is the management of any radio station (primary or backup) connected at this time to this Rebecca address rewriting; in Fig. 3 is a functional diagram remotes operators.

Multi-channel device for reserving radio contains the basic radio 1.1. ..1.M and backup radio station...2 2.1.N, consisting of the receiving register 3, decoder 4, block 5 electronic frequency tuning of the transceiver 6 and unit 7 of the control unit 8 controls the switching of the moving allowance, unit 9 address rewriting, control stations 10.1...10.M, bus 11 of the control commands and the bus control 12 stations, respectively, the first input and the first output unit 9 rewriting and addresses, and the second inputs 3 and second outputs 14 block 9.

The outputs of the transceivers primary and backup stations 1, 2 through the control units 7 are connected to the inputs of unit 8 controls the switching of the moving allowance, the outputs of which are connected to the inputs 13 unit 9 address rewriting, the group outputs 14 which are connected with inputs of survey panels 10 control stations and another output unit 8 bus control 12 is connected to the control inputs of the main and backup channels 1, 2. The outputs of the consoles 10 control stations via the bus 11 of the control commands is connected to the input unit 9 address rewriting.

Blo is ATOR 20, the first and second elements 2I 21 and 22, the first and second elements 23 and 24 and the element 25.

The remote control 10 control stations consists of a keyboard 26, block 27 of the memory address of the remote encoder 28 commands of the inverter 29 parallel to serial Converter 30 unipolar code in bipolar divider 31 frequency.

When you implement this device as a block of 8 was used, the control unit switching the moving of the reserve.with. N 1329444.

Concrete block structure 8 is determined by the requirements of a rolling reserve: conservation status switching during power failures, the order of connection of the backup radio stations, the number of primary and backup radio stations, as well as the specific circuit decision and used element base. As developed blocks 8 can be used by device A. with. N 545985, N 703816, N 1107127, N 1378651.

As stations 1 and 2 can be used radios that are managed by the serial code (R-800, R-833, R-805, and so on).

The device operates as follows.

All the radio stations and control panels are assigned sequence numbers, which are recorded in 2.1...2.N are the sequence numbers from M+1 to M+N. Consoles 10.1...10.M control stations have the sequence number of the communication directions, corresponding to the main radio stations - 1 M. From the keyboard 26 10 remote control station selects ranges of operating frequencies and modes of operation of radio stations. This information is encoded by the remote control 10 and the serial word is supplied to the multiplex bus 11. The bus 11 is connected to the first input unit 9 address rewriting, which is intended to replace in case of failure of any major radio stations in the code package transmitted by the remote control, the address of the failed radio station address replacing it suitable backup radio. Management by replacing radios provides unit 8 controls the switching of the moving allowance, which works on generalized signal "Failure", coming from the control outputs of the radio stations. Connection backup radio stations is determined by the algorithm used block of 8.

In the absence of failures in radio stations all outputs 13 of the control unit 8, there are no commands to switch to the reserve. Therefore, the control code combination with bus 11 in transit, passing through the block 9 and is supplied to the bus 12 upravliaiushchaia.

The receiving register 3 converts the bipolar input signal to a unipolar, then allocates a pause between code words, after which it is recorded code word in the register. After recording all the words of the receiving register 3 compares the address part of the code sending the address assigned to the radio station, and when the coincidence of these addresses writes the received code word in RAM register 3.

In the receiving registers 3 stations recorded only the message frame, the address of which corresponds to the ordinal number of the station. Adopted code package arrives at the decoder 4, the output of which control commands are received at block 5 electronic frequency tuning and Primobolan 6. Similarly, all major radio stations will be configured in accordance with the information typed on the remote control. Failure occurs at any radio station, for example two, the control unit 7 issues a "Failure" signal, which is supplied to the unit 8 controls the switching of the moving allowance. This unit in case of expiry of the backup radio output 13.2 issues, for example, the command On.1 rez. instead of 2 regular. " Coma from the second remote 10.2, replaces the address of the second station on the sequence number of the first backup radio M+1. Thus, the control commands transmitted by the second remote will be taken to the receiving register 3, the first backup radio stations 2.1, which will automatically tune to the frequency and mode of operation of the failed main radio stations. Upon further failure of the main or backup radio stations restructuring plug fit Unallocated reserve radio stations will be the same way.

Unit 9 address rewriting works as follows.

The spinner 16 is from a generator 15. The number of least significant bits of the counter corresponds to the word length, in terms of control commands transmitted by the remote 10. The number of high-order bits corresponds to the number of binary digits in the number of all radio stations. The first multiplexer 17 provides a connection to the encoder 19 command groups (Incl.1 rez; Incl.2 rez; Incl. N rez. ) acting by the circuit 13 in synchronism with the address of the respondents operator. Synchronous connection command groups is provided by the code of the survey, arriving at the same time on the control inputs of the multiplexer 17 and through the decoder 20 to the circuit 14 at the remote operator 10. Except this is the one. The encoder 19 converts a decimal number command to switch to the reserve in a binary number, plus the number of M - number of main stations. Thus at the output of the encoder 19 in case of failures in the major radio stations will be in sync with the survey panels failed radio address plug back radio stations represented in binary code.

In the absence of failures in the major radio stations all outputs of the encoder 19 will be the log. "0", the output element OR 24 will also be present log. "0", which closes the element 2I 21 and to the input of the element 25, the output of which the signal log. "1" is fed to the input element 2I and 22. Therefore, all information received via the bus 11 to the second input element 2I and 22 will pass through it and then through the element OR 23 on the bus 12 management facilities. Thus, all major radio stations configured in accordance with the control commands transmitted to them with panels 10.

In case of failure, for example, the second main station at the entrance 13.1 On.1 rez, instead of 2 regular." will appear in the log. "1". During the interview panel 10.2 multiplexer 17 connects the team On.1 rez and the first output is the course of the encoder 19 at this time appears a binary code number (1+M), which of the multiplexer 18 is converted into a serial code, i.e., the multiplexer 18 provides serial connection of the binary digits outputs of the encoder 19, to one output. Alternate connection of the input signals is provided by applying to the control inputs of multiplexer cyclic code with the second output of the counter 16. Thus, at the output of the multiplexer 18 is formed serial address code plug-backed radio station. This serial code is supplied to the first input element 2I 21. Because at a certain input element OR 24 is present in the log. "1", the output of this element will also be a log. "1" which is supplied to the second input element 2I 21, allowing the passing of the information generated by the multiplexer 18. This information representing the address of the plug-backed radio station, through the element 23 is supplied to the output bus 12 management facilities. At the same time log. "1" output from the OR element 24 is supplied to the element 25, the output of which the log. "0" is fed to the input element 2I 22 forbidding the passing of the code of parcels arriving at different input from the bus 11.

After completing adresuetsya log. "0", which prohibits the passage of information from the multiplexer 18 and permit the passage of information on the control commands from the bus 11 through the elements 22 and 23 to the bus control 12 radio stations.

Thus, when the refusal of a radio unit 9 address rewriting performs automatic replacement in the code sending the address of the failed radio station address of the backup radio. The management of the connected stations will be carried out with the same remote control.

From the remote control 10 control controls the operation of which is connected to the workplace (operator) station. The keyboard 26 is the choice of the operating frequency, mode and other settings work stations that potential signals are received at the first inputs of the encoder 28, the second input of which is to block 27 of the memory address is remote. The encoder 18 converts the control commands and the number of remote code word transmitted parallel code Converter 29, which together with the output of the inverter 30 and the divider 31 frequency operates in two modes - idle mode and the transmission mode information.

In real ozluce output Converter 30 is in a state of high output impedance, i.e. the output of the remote control 10 is disconnected from the bus 11.

The transmission mode information, consider the example used in the device output code according to GOST 18.977-79. At the time of the survey panel 10 from the decoder 20 unit 9 to the circuit 14 to the input of the inverter 30 and the divider 31 receives a sequence of clock pulses. The divider 31 provides for the formation of time intervals code words, which are fed to the input of the Converter 29. The Converter 29 performs a sequential read of data from the encoder 28, resulting in the output of the inverter 29 is formed of a unipolar consecutive 32-bit code with a pause 4-8 bits after code word. The output of the Converter 30 during the pulse survey converts unipolar code in bipolar code that is transmitted over the bus 11 to the block 9. Thus, each panel 10 control sequentially connected to the bus 11 and transmits control commands and bus 11 will be cyclically transmitted 32-bit words from each remote with pauses between words in 4-8 bits. The first part of the code word is the address of the remote controller 10 (the address of the communication direction or main station) and the second part of this is in the proposed 10 remote control stations implemented in the remote station R-LM (block 32).

Improving the reliability of device operation is achieved by introducing a sliding reservation stations, a significant reduction of the switching field of the relay switches are used to switch radio stations, by eliminating switching through them command control radios and reducing the number of control wiring due to the transfer stations for telematic management.

The expansion of the scope of the device is achieved by redundancy of radio stations operating in different modes, allowing you to plug back the radio station to produce in addition to adjustment of the operating frequency setting modes radios (PHONE, GCL has, type of modulation, and so on).

Improving the efficiency of operators, reducing the time to manage radio stations is achieved by the introduction of remote control, providing management with workplace primary or backup radio connected to this workplace, i.e. the direction of the Association is assigned to that operator. There is no need to install on the remote control modes of the emergency radio stations, connected instead of the failed primary.
