responsibly with the inputs of the comparison units 36-39, the output of the latter is connected by the input of the address setting unit 40, another input of the comparison unit 39 is connected to the output of the AND element 41, one of the outputs of which is connected to the control key 42, the output of which is connected to the input of the memory block 43 the computer whose address inputs are connected to differentiating unit 44.

A device for remote control of dispersed objects works as follows.

The computer unit 43 comprises a program task for managing distributed objects (block posts) 1.1-1. Depending on the state of the block 40, which transmits commands to the address inputs of the block 43, control outputs for a specific block post are generated at its outputs. The same control commands are generated at the first and second outputs of block 43, which are received respectively at the third inputs of the encoders 29 and 31. The latter form a sequential code, which includes information: the address of the checkpoint II, for which control commands are transmitted, the control commands themselves and check bits that determine which encoder 29 or 31 transmits the code To the link 22, the initial state of the posts 1.1-1, n and the central post 23 is the reception mode, but the reception mode of the central post 23, while the 22c line is unavailable, a small time is maintained, which is determined by the timer 35, and after a predetermined time has elapsed, the central post 23 is put into transfer mode. In the initial state of the central station 23, the triggers 25 and 32 are in a single state. A trigger 25 with a logic zero signal sets the switch 24 to the receive mode that connects the communication line 22 and the input of the decoder 33.

516 From the direct output of the trigger 32, the signal of the logical unit through the elements OR 26 and 27 steps on the prohibition inputs of the encoders 29 and 31, sets them to their initial state, and stops their operation. The trigger 32 acts on the prohibition inputs of the encoders 29 and 31 and confirms the prohibition of the operation of the encoder 31 and prepares the encoder 29 for operation. From the direct output of the trigger 32, the signal also goes to the second inputs of the encoders 29 and 31.

As soon as timer 35 counts down a predetermined time, the signal from its output through the element OR 34 switches the trigger 25 to the zero state, which switches the switch 24 to the transmission mode, i.e. connects the communication line 22 through the OR element 28 to the outputs of the encoders 29 and 31, resets the decoder 33 to the zero state, removes the ban on the encoder 9. The encoder 29 begins to output the code signal to the communication line 22, which is fed to the inputs .-outputs of switches 2 checkpoints 1.1-1.p. But since the code signal contains a specific address of the checkpoint 11, for which the control information is intended, this code signal only receives a certain block-post AND,

Switches 2 checkpoints 1.1-l.n are in receive mode, i.e. they connect the communication line 22 to the input of the decoder 3. The latter receives and decrypts the code signal arriving at its input. The first output of the decoder 3 generates the information of the address of the post, coming from the central post 23. This information comes to the comparison block 7, where the information also comes from its own address block 8, If the address coming from the central post 23 coincides with the address of the address block 8, then a signal appears at the output of the comparator unit 7, which transfers the memory blocks 10 and 11 from the read mode to the write mode.

The signal from the output of the first comparison unit 7 also enters the control output of the (sample) trigger 17, which retains its state, and logical units are formed at its forward and inverse outputs, thereby trigger 17 sets the encoders 15 and 16 to their initial state .

In addition, the signal from the output of the comparator unit 7 includes in one state trigger 6, which, in turn, includes the control key 5 with its direct output signal and connects the direct output of trigger 4 to the control input of switch 2, Switch 2 remains in the receive mode, at the output of the controlled key 5 the logical zero signal is preserved, since the trigger 4 is in the zero state.

At the second output of the decoder 3, a signal is generated acting on the switch 9, which connects the third output of the decoder 3 to the output of the memory block 10. The position of the switch 9 is set from the central post 23 by the trigger 32, the state of which is encoded by the encoders 29 and 31. Consequently, the information from the first output of the block 43 will be recorded into the memory block 10 at the block post 11

computer memory via the first encoder 29 of the central post 23.

As soon as the transmission of information at central station 23 is completed, at

the second output of the encoder 29 by the Wits signal, which through the element OR 30 sets the trigger 25 to one state and, in turn, removes the prohibition from the decoder 33, switches

the switch 24 is in receive mode and disables operation of the encoder 29, sets it back to its original state and removes the code signal from the communication line 22. There is a pause and on the fourth

The output of the decoder 3 of the block-post 11 appears a signal that switches the trigger 4 to one state. The signal of the logical unit from the direct output of the trigger 4 resets the decoder 3 to the zero state and switches the switch 2 to the transfer mode, i.e. connects the communication line 22 through the second element OR 19 to the first outputs of the encoders 15 and 16.

Resetting the decoder 3 leads to a mismatch of information at the inputs of the first comparison unit 7 and a logical zero signal appears at its outputs, which removes the prohibition from the second trigger 17, and its forward and inverse

the outputs appear signals corresponding to its state, therefore, the prohibition is removed from the encoder 15, which generates a code signal into the line

22 communication at the central post 23, This code signal consists of the own address of the block-post 1, information from the output of the memory block 10, information on the state of the switch 9 and control information from the outputs of the control block 14,

The code signal from the output of the switch 2 of the block post 11 arrives at the central post 23 and through the switch 24 arrives at the input of the decoder 33, which receives this signal and decodes it. At the first output of the decoder 33, the information of the address of the block post 11 is generated, which is fed to the first block 36 of the comparison. If this information coincides with the information of the block 40, then a signal appears at the output of the first block 36 of the comparison, which enables the operation of the block 37 of comparison.

From the second output of the decoder 33, the status information of the switch 9 at the block-post 11 is fed to the input of the second block 37, which must correspond to the state of the trigger 32. When this information coincides, the signal at the output of the block 37 appears, which enables the block 38 and includes a control key 42 which connects the fourth output of the decoder 33 to the input of the memory unit 43 of the computer.

The information of the third block 38 is compared with the information on the first output of block 43. If the information on the inputs of block 38 is the same, a signal appears at its output that switches trigger 32 to the zero state, thereby preparing the encoder 31 for work and prohibiting work the encoder 29. From the fourth output of the decoder 3, information about the operation state of the blocks 1.4 of the control of the post 11 enters into the block 43 of the memory,

As soon as the transfer of information from the checkpoint to the encoder 15 is completed, a signal appears at its second output, which sets the trigger 17 to the one state, and it, in turn, prohibits the encoder 15 from working and, gives permission to work to the encoder 16 and the first element OR 18 sets the triggers 4 and 6 to the zero state. This leads to the removal of the prohibition from the decoder 3, the switch 2 switches to the receive mode, and the control key 5 is turned off.

In line 22, a pause occurs, which is perceived at central station 23 by decoder 33, and at its fifth output a signal appears that resets timer 35 to the zero state, through the third element OR 34 sets the trigger 25 to the zero state, which, in turn, switches the switch 24 in the transmission mode, resets the decoder 33 to the zero state, removes the prohibition from the encoder 31, which will transmit the code signal through the OR element 28 and the switch 24 to the communication line 22 for the same block post 11 but this code signal is encrypted Attorney 31 generates commands from the second output of block 43, and also from block 40 and direct output of the trigger 32. This information, as in the first case, is received at block post 11 by the decoder 3 and is processed in the same way as in In the first case, only switch 9 is set to another position, since the second trigger 32 at central station 23 switches, and the information at its output becomes intense and connects the third output of decoder 3 to the input of memory block 11, into which the control information is written .

Upon completion of the transmission of information from the central office 23. the same block switching takes place as in the first case, with the only difference that at the block-post 11 the encoder 16 transmits the information to the communication line 16. At the central post 23 the incoming code signal as in the first case, the decoder 33 and blocks 36 and 37 are processed, and if the information at the inputs of the comparison blocks 36 and 37 coincide, the signal of the logical unit that enters the input of the element 41 41 appears at the output of the block 37, on the other entering it. there is already a logical unit from the inverted output of the trigger 32, which switches to the zero state by the signal from the output of the block 38, therefore, at the output of the element 41, there appears a signal that allows the comparison of information from the second output of the memory block 43 and the third output of the decoder 33. If the information at the input of the comparison unit 39 is the same, a signal appears at its output that receives the input of the address setting unit 40 and changes it

y the address for accessing the next block post 1.1 + 1. Changing the address n output of block 40 changes accordingly and control commands at the outputs of block 43, and also briefly switches on differentiator block 4 which sets trigger 32 to its initial unit state.

After a pause in the communication line 22, the switch 24 of the central post 23 is again switched to the transfer mode and the central post 23 will transmit information already for the next block post l.i + li. At the previous block post 11 with equality at the outputs of the multi-bit blocks 10 and 11 pm the signal from the output of the second unit 12 of the comparison is fed to the input of the mode

ma Recording and translating memory block 13, which overwrites information from the output of memory block 11. From the output of block 13, the signals are fed to the inputs of block 14 of the control of this object (block-post 11),
