The device works as follows.

The generator 1 generates a sequence of pulses that arrive at the first inputs of the first counter 2 and shaper 4. The counter 2 receives the first address sign at the third shaper input from the memory unit 5 at the first input of the first pulse from the generator 1 four.

The imaging unit 4 transmits to the communication line with the linear sets a pulse corresponding to the memory of the parameter address address read from block 5. The address pulse has a positive polarity. The shaper 4 according to the second signal from the first counter 2, which arrived at its second input in the second cycle of the device operation, forms an advancement pulse whose polarity is inverse to the impulse of the address value. In this way, an address parcel is formed, consisting of K 26042 P address and pushing the impulse, and the value of BSC)

The nearest greater integer number of linear sets of the device is taken. Address parcel is intended to include one of the first line sets. Line 5 sets are connected alternately. Prodigm pulses are designed to record address pulses in an ibod-g shift register. The shaper 4, according to the signal from the first counter 2, generates a polling pulse, which has a positive pop and follows the communication line after each address packet. Thus, the cycle “i-dew of all essential sets will hold 5” (2609-2 -I) j, the device operation cycles.

All linear sets work in the same way. In the initial state, all switches have 7 connectors.

0 chen their first exits.

The address impulse goes to the input. the first linear set and through the switch 7 enters the input of the decoder 8 polarity and the third input of the element

5 OR 15. Through the element OR 15, the address pulse is received to the input of the next linear set. The address impulse received at the input of the polarity 8 decoder, from its first output, goes to the first input of the shift register, U, and is written to its first cell.

The progress of the impulse passes through the switch 7 and gets to the input of the decoder 8 polarity and the third input of the element OR 15. Through the element OR 15 the advancing impedance arrives at the output of the linear set. A pulsing pulse passes through the decoder 8 of polarity and from its second code enters the first input of the second counter 9 and second

® A swarm of the shift register U, shifted the contents of the register one row at a time, thereby preparing its first cell to record the trace address sign. Second counter 9 counts

 about moving impulses. Upon receipt at the first input of the second counter 9 of the last forward pulse

address parcel, it generates a signal that from its output goes to the second

the input of the switch 7, connecting its second output for one clock cycle, and the third input of the shift register U, read the contents of the shift register U to the decoder 12. The shift register Yu is shifted

this is nullified. The decoder 12 analyzes the address code, read from the register 10 shift, and outputs a signal to one of the inputs of the trigger 13. In the case

code, .zap ;; sdn} and, | h; d shift register Yu, conformance; The turn-on code of this line set, 1.2 decoder, gives a signal to the first input of the trigger 13, As a result, the flip-flop 13 sends a signal to the second input of the third element 14, If the coi read from the register 10 of the SONEgas does not correspond to the turn-on code of this linear The decoder 12 generates a sigiap at the first input of the trigger 13 ;, which opens the second element 11 by this signal, applying a signal to its second input.

The polling pulse arrives at the input of the linear set in the next clock cycle after the address parcel and through the switch 7 enters the first inputs of the second and third elements AND

B. If this linear set was not turned on, then the polling pulse through the second closed O 11 element and the OR 15 element enters the connection with the next linear set. In case this linear set is on, the polling impulse is transmitted through element I 14 and element OR 15 and goes through the B line with other linear sets. Thus, the polling pulse, in the case of the normal state of the object being polled, will go to the second input of the first element AND 6. The first element 6 opens with a signal from the second output of the first counter 2 at the moment of the arrival of the polling pulse T1. The polling pulse through the open first element AND 6 is fed to the input 3 of the call-in groups that are fed to the second input from the third E, the output of the first 2. They identify in block 3 the polled linear set. The polling pulse on the persistent input of the ringing unit 3 at the moment of displaying in block 3 of the number of the polled linear set 16 indicates the normal / GoC condition of the controllable object

If a violation occurred on the kit polled by the linen, they did not pass the polling, through the closed third element 14, then at the time of displaying the 3 ring signals the numbers of the polled linear signal set on the first input of the block 3 did not appear. which indicates a violation of the scientific research institute on the interrogated linear set or TOMg that a violation of communication kicks occurred between the linear sets and the control room.

Check the health of the communication line wasp

This is accomplished by applying to the communication line an address / bus to turn off all the linear sets and a polling pulse. The line of communication will be operational if the polling pulse arrives at the input of the 3 ringing unit. The polling cycle (in cycles) of all the linear sets of the prototype is M-2 -I, a cycle, and for the proposed device, N-n (2 & og, n + l) cycles. DoN N or
