Channel recording device operates as follows.

Clock pulses come from the generator output 2 clock pulses to the input of the distributor 3 pulses and start it. The distributor 3 pulses continuously polls the state of the monitored nodes of the object by means of clock pulses formed by the shaper 8. From the drives of the shaper 8, the clock pulses are sent to the amplifier 10 and one input of the first group 4 of each element I. After preliminary amplification, the clock pulses are recorded with one polarity in the magneto-recording unit 1; When the monitors of the monitored node are in the initial state, the sensors of the information sources 5 are triggered and temporary outputs appear at their outputs pulses that arrive at the other inputs of each first group of 4 I elements, and at their outputs there appear pulses that trigger the corresponding single vibrators 6 ". As a result, at the outputs of the single vibrators 6 appear calibrated pulses, which after forming by the formers 7 information pulses J are amplified by amplifier 9 and recorded with the other polarity in the magnetic recording unit 1 per one magnetic tape track. In this case, the informational impulses of each node, showing the number of cycles and the operation time of the object's nodes, are located next to the corresponding ILI and II clock pulses, and the last output of the distributor 3 is used to form a 1C1 sync pause between the cycles of the operating pulses. This is due to the necessity of the operation of the distributor 14 pulses of the playback channel (Fig 2) in the start-stop mode. In this case, the end of a long pause or the beginning of the next clock pulse is the starting one, and the beginning of the pause is stop.

The playback time ((jMr, 2) of the device works in the following 1M way, From the clock of the playback unit 11, the clock to the information pulses are sent to the blocks 13 and 12 by the outgoing clock and information pulses, which are allocated, the selected clock pulses are simultaneously received The input of the time selector block is 15 clock pulses at the first input of the third element I 32 ,.

The principle of operation of the circuit of the block of the temporary selector 15 clock imputs 3 akle ae t with ate ed uuste m „

The pulses coming from the output of the block 3 of the clock pulses, at the same time, the input to the inputs of single-vibrators 29j of the delay element 36 and to the first input of the third element 32 And the single-oscillator 29 starts from the single-pulse 29 and produces a pulse with a definite duration of which is a hustle at the input of the PTI 37 element. output impulses dsY ;, arriving at the input of the delay element 36, time-shifted j arriving at the input of the third one-one 30 and starting it. The vibrator 30 also produces it with certain oh duration; which arrive at the input of the element ITSh 37, Total impulse duration,:; The single-shot 29 and 30J produced is equal to the repetition period of the mezdz / tact ig-shulsa 4i „

Thus.) If the repetition period by clock pulses is less than or equal to the given one, then the output is SH. 37, according to the time of the imguls, the duration of which is equal to the sum of: the time period of the repetition period, the current is mi mi with ami.

If periods of repetition; between clock HMnynbcaivQi more. given, then the output of the element OR 37 will disappear a time pulse j which means the end of a series of clock speeds Km-coBj as a result of the output of the element HE 34 is logical; 1, in the event of a reset pulse of the distributor 14 IGULSO. preparing it to receive the first 1 pulse of the pulse. Simultaneously from the output and the element OR 37, the pulses are fed to the input of the second element AND 31,

During playback of clock and informational pulses due to

Negative installation of a magnetic tape against the risks of 1GLI due to the impossibility of recording information1 ;; and from the first clock pulse, information can be read; 5 not from the first one (informational) pulse, but from another (any) . Then, when sc, it happens, an error occurs, and the information corresponding to the first channel can get into any other channel. Such an OE-bending has a sushi influence even when taking into account the number of operation cycles of nodes. To eliminate this error, it is necessary to drop (reset) the first ser.u. clock and information pulses. The problem can be solved by the prohibition scheme. the first series of infor, matsinkk ig-puls. The trigger 33 is triggered from the trailing edge by a pulse, its pulsing and in the initial state at the output of the element NO 35 there is a logical 1.

At the output of the tr. Igger 33, a pulse of 25 each after the pulse disappears: the outputs of the iUTIi 37 and HE 35 elements and later are held irrespective of the change in impulse at the output of the OR 37 element, since the second

30 input element and 31 will disappear in a logical way Taim-iM after perk

a series of clock and information pulses at the output of flip-flop 33 in accordance with a logical l, which is supplied; It connects to the first inputs of the elements AND 32 A and 28 and is held until manual:; bgzosa.

The commencement of this temporary impulse is a command that resolves the And 32 and And 28 elements to skip the clock and informational use for reading:. Since, at this time, the frequency of the e, l: element AND 32 receives the i-OBb e pulses, after the appearance of the first input of the element, Pi 32 logic 1 second, clock and 1 pulses, start. ;.: ayut arrive at the input distribute ;;; 4, From r; clock speeds that are set to: pulses on Eb; the moves of the distributor 14 needles alternately appear imi jiyjibCbij kotrye go to other tracks of the second group 16 e, letters I.

Information pulses from the output of the block; 2 pulses of information pulses are fed to the input of the rotator 21, the output of which is by cc.h.p. pulses, the duration

which is greater than the duration of the input pulse.

In this case, a corresponding coincidence of the corresponding clock and information pulses is ensured, and their binding is created due to the synchronizing pause formed between n-1 and the first clock pulses. From the output of the one-shot 21 information pulses, extended in duration, arrive at the other inputs of the second group of 16 elements I. At the output of the matching logic circuit, the information pulses appear only when the logic 1 turns off at the output of the trigger 33.

Since information pulses are recorded next to their clock pulses, when the first clock pulse appears at the first output of the distributor 14, the first information pulse appears at the output of the first AND element of the second group of 16 elements And the first information pulse, etc. Further, these decoded and consecutive information pulses arrive at the corresponding inputs of the node operation hours 17 and bit accumulate until the end of the processing of the magnetic tape.

If the repetition periods between clock pulses are equal to or less than the specified ones, there is a logical l at the output of the element NOT 34, causing the distributor 14 pulses to the initial (initial) state. Thus, after each n-1 pulse, the distributor 14 pulses starts counting from the first clock pulse.

Using elements 24-27, repeat periods are compared to 2001

The information pulses that are in the next series with the given one. In this case, if the repetition periods, for example, of information pulses of the first channel located in adjacent series are equal to or less than the specified one, then the one-shot 26 and 27 produce pulses, the total duration of which is sufficient for not holding the output element OR 24 logical l, which corresponds to the on state (operation cycle) of the monitored object node.

(5 Otherwise, the logical element 1 will disappear at the output of the OR 24 element, which means the end of the node’s operation (end of the operation cycle) of the object. Thus, depending on

20 incoming information pulses at the output of the element OR 24, temporary pulses appear corresponding to the number of operation cycles of the nodes, which are stored by counters 22 and 25 pulses until the end of the processing of the magnetic tape.

After finishing the processing of the magnetic tape by clicking on the corresponding keys of the block of 20 keys. On the digital display block 19, you can get information about the number of cycles and the operation time of the object nodes.

The proposed device allows, without changing the number of recorded pulses and magnetic track, to obtain

 additional information about the operation of the nodes of the object being monitored. Thus, the use of the invention leads to an increase in measurement accuracy and control efficiency.
