The drawing shows fncc Enalcay device diagram. The proposed device contains 3) er, g; rv11rov. channels 1-3, corresponding to each channel - comparison schemes 4-6 ,, GjiOKH adantacin 7-9 rebuilding organ 10, output element ILM 11, figger 12. Each node adantacin 7.8 and 9 sod1) has four elements AND 13-16 , imitation trigger 1 17, imitation trigger O 18, element OR NOT 19, element ILM 20 and failure indicator. 21. The device operates as follows. In the initial state, the imitation trigger I 17 and T1:) imitation 0 18 on their single outputs is low potential, and the single output of trigger 12 is high potential. The imitation tripod O 18 issues from the zero output to the second input of the fourth element I 16 permit (the floating terminal, i.e. the fourth eleiek I 16 is open. Since the single potentials of the imitation trigger 1 17 and the trigger imitation 18 are applied to low potentials two inputs of the element ILINE 19, then at its output a resolving potential is formed, which opens the first eponent of I. 13 on the second input and turns off the fault indicator 21. Informgshik from the output of channel 1 and analogue from other channels 2 and 3 through the fourth fourth element I 16 and element AND LI20 from informatsionny The output of the flea adaptation arrives at the input of the recovery body 10, Information from the output of the recovery body 10 simultaneously with the load you receive its Tie with information from the redundant-X channels, goes to the inputs of the respective comparison circuits 4When comparing these information, i.e. failures in the reserved channel at the output of the srzsvnenk circuits, there is no control signal. When a failure of the channel appears ,,. (for example, 15th circuit of the svsvneik 4 outputs a signal to the control input of the adaptation block 7 and the first input of the first ementa AND 13 which is open at the second input, Perv5Y vydaotlgnal AND gate 13 to the second inputs of the second and third elements m 14, and 15, with the unit output. trigger 12, the resolving potential is applied to (. The first input of the third element 15, which gives a signal to the single input of the trigger 0, 18 and sets it to the single state; Simulation trigger 18 closes the second input of the fourth element) p-a and 16, which corresponds to the above T) from the output of channel 1 to the first input of the restoring organ 1O, the issuance of the figmara of the imitation O 18 of the resolving potential from the upper exit. to the second input of the element OR NOT 19. leads to the appearance of a low potential at its output, which locks the first element I 13 through the second input, zashch. thereby further adapting the output of channel 1 and turning on the failure indicator 21, which signals the failure of channel 1. At the same time, the signal from the output of the first element I; 13 through the signal output of the adaptation block 7 and the output element OR 11 enters the counting input of the trigger 12, which switches to the zero state at the end of this signal. The interlocking potential from the zero output of the trigger 12 opens the second element I 14 and similar elements in the other input adaptation blocks 8 and 9. When a channel fails, for example 2, it becomes impossible to compare information at the input of the comparison circuit 5, and it will generate a signal to the first element 13 of the adaptation block 8, which outputs a signal through the open second element 14 to a single input trigger imitation 1 17 of this block-adaptation. Imitation trigger 17 generates a single signal instead of the input signal of the failed channel 2 via the OR element. At the same time, the imitation trigger 17 through the element OR-i-fE 19 disables the subsequent adaptation of the first element AND 13 to receive the subsequent adaptation signal 21 channels 2. The signal from the output of the first element 13 through the signal output of the adaptation block 8 n the input element OR 11 enters the counting input of the trigger 12 and switches it to the unit state. Thus, the adaptive redundant device Traversing the input of the restoring authority, by issuing instead of some of the failing ones. There is a channel of zeros in the order of the occurrence of failures, channel-zeros, and instead of others, for example, counted} | on the order of occurrence of failures, channels / unit, ensures the system operability with (-2) failed channels, regardless of the location of the failed channels relative to each other, and. order of occurrence of failures in the channels. The subject of the invention 1.
