Description

M; psstse relay electromapshIs devices d; | Registration of a series of serial needle pulses requires a significant amount of pe-ie. The proposed device allows halving the amount of loss of the H1JX relay in the reverse mode. However, as a result of the -jToro reversal, the aiSTO system returns to the jicxo,.; Joe position at the end of the registration by determining one or a certain number of pulses and pauses, or pulses.

FIG. I shows a schematic diagram of the npe; uiarae Moro device; in fig. 2 shows the circuit of the chains, after the circuit .1 but it is closed. With the help of the device according to FIG. i; FIG. 3 represents the schema of an additional; 1nite.-1 device for slower registration, limiting it to retrest, for example, only pulses.

FIG. i L, L, L., denote the contacts of a transient relay, triggered by incoming pulses, which can be calculated

or must create a switch in the distributor circuit; I, 2, 3 designate registering (counting) relays; P - rs.che, reversing (reverse).

The operation of the circuit is as follows.

At the beginning; | nny moment of time, all relays are farther. In the case of a postch pulse relay relay .7, the contacts of the tees, are switched alternately to the upper and lower positions. When applying the first impu.pla will be applied to the pe-ie / winding through the bottom contact P, the top contact of the tee .7 ,, bottom contact 2.. The second end of the winding of the relay 7 is connected to the battery plus, pe; ie J will work and block the forces. preparing your contact circuit the next counting relay 2.

When released, it is barely L, t, e. At the first pause, relay 2 will operate and lock up, prepare for ".1 twisting its own contact with the circuit of the following counting relay 3. Simultaneously, the circuit

pc-ic /, which, however, remains, is -1 m.

1 (to the fact that it was at the first i; v.ny: ibce and the first pause with cMtTHiJM pe.ic / and 2 will occur at each; 1) .m the next impulse and the corresponding pause with each next pair of counting relays. At the second 11mpu; | hs the relay J will work, at the second pause the relay 4 will work, and so on (Relay 4 is not shown in the diagram). Thus (“sequentially, one after the other, all countable rsyu from I to n work together — one when nmphmsa is applied, during a pause.

After the relay / triggered, which occurs when the nmp-l1d is applied, a, with the following impulse science: k, the re-sprint rss- / - is triggered on the circuit: plus, the bottom contact .7, the top contact l, the winding rssl P, -viiiiyc. Relay P, activated, is blocked through the upper contact 7.

1} as a result of the operation of the relay P, the price of the TroGschik contact .7 is closed and the circuit of the Trogshkovo contact is closed, 1. The plus is fed to the winding L via the upper contact P, the lower contact of the tee L ,, the upper contact n - 1. shunted, due to which the relay is unlocked and with its contact, prepares the d.G.1 circuit of the L-I relay.

When you start a new impulse, the n-1 relay is unlocked, when you post a new pause, the n-2 relay is unlocked, and so on.

The counting relays are released once, in the order of decreasing numbers, until iioKa unlocks relay 7 at the end of the counting impulse stp. When the relay 7 is dropped, the relay 2 is also unblocked, as a result of which, the circuit at: goes to the initial state.

The total number of d.che d-h counting 2l pulses n pauses l-p 1, i.e., almost half the total number of pulses and pauses.

FIG. 2 is a diagram of the circuits sequentially closed by the contacts of the relay /, 2, 3, ..., n during the operation of ycTpiiHcTBa, but FIG. I. As shown but

in fig. 2. With the help of this feature, you can control 2n tsei: li ,. where n - number: t of the relay in the chain.

As / ke, device P (; Fig. I is intended for d. 1 of the C-1's account and i.ic.iij. It is necessary to count the To.ibKo pulses, add replacement, 1; | to the diagram on. 3. According to this scheme .1 it is easy to trace that the rate of operation of the relay Ln8 is slower than two times as compared to the rate of operation of the relay .7. Therefore, if instead of the contacts .7, // j, .7 fng. 1 enter pe.ie contacts A, counting pe; ie, circuits ({«« syvat only impu.chky. In this case, the total number; the number of relays for the nn account 2p is equal to l + 3, i.e. for P (dcount 40 nmpul1 C (23 relays required, for counting W and Mpulsov 1tc 33 relays hd

If the number of counting relays is odd, the contact L in the value of relay P is made to open. If the number of counting relays is even, the co-act L in the relay circuit P in: .1 is filled for a short circuit (shown in Fig. I by a dotted line).

If it is necessary to count a very large number of computer codes (or pmpu.chs and) with the help of the corresponding groups of counting relays, it can be (there is only one (tenth or some) counting system for the one-way dependent counting, dsc tc ( ) In units, hundreds, etc.

For example. For counting a hundred pulses, two grkhchni can be applied. relay, 8 relays in each grlin - unit counting and ten counting units} | itz. Gross counting of units is up to.File andDid counting emulsions directly coming from the line or from some kind of pulse generator. This pe.ie through each ten iu.iuli completes the; i1 and the counting cycle and comes to its original state. The reversing re-P is triggered and releases O; UHI time after time, each cycle.
