SU64776A1 - The method of controlling the forced motion of the step finders - Google Patents

Description

The proposed control method aims to build a simple step-by-step rotator circuit, while respecting the tentative numbering of subscribers and the possibility of switching on paired subscribers without selecting an individual set of contacts in the searcher field for each of the paired subscribers. To implement this method, a prerequisite is that the searcher has time to make a free run of the contacts of a decade during the passage of one subscriber pulse, for which the number of contacts per decade must be limited.

The essence of the present invention is that the installation of the finder brushes on the required contact is carried out (in accordance with the decade numbering) by directly affecting the finder electromagnet of tens and units sent by the impulse relay during the broadcast of the pulse 1B1, so that The decade selection took place with the free run of the searcher of several contacts, for example, four, for the duration of one subscriber pulse, and it was possible for the searcher to work at normal speeds by developing small decades into five, four or three contacts — at the beginning of the floor and decades of large capacity — at the end of the floor, and the breakthrough of the corresponding decade was excluded due to the dependence of the last step of the decade on the reverse attraction of the impulse relay at the end of the pulse. In this case, paired subscribers with individual numbers, but without individual contacts for each subscriber, are switched on by automatically switching the ringing current from one wire to another depending on the parity or oddness of the sign of the ten dialed numbers.

The foregoing summary is illustrated in the drawing. FIG. Figures 1 to 4 of the drawing show various variants of the schematic finder scheme in which the proposed method is carried out.

FIG. Figure 1 shows the case where the 50-pin rotary finder field is divided into 10 decades with 5 contacts in each decade.

When the impulse relay IL is released for the first time, the linear searcher magnet of the ILI is switched on through its self-terminating contact SPK, brush d and initial contact, contact of the burglar relay OP and contact a of the relay IR. The MLI finder triggers and opens its SPK, whereby the MLI turns off, releases the measles and moves brushes B: the next position. Then the MLI is turned on through its SEC, brush d and four parallel contacts of zero, decade, connected to the battery plus for the entire period of the decade selection; as a result, MLI pulses and moves the brushes to the 5th detached contact of the zero decade. If the decimal sign I is typed, the brushes will stop on this contact, which is prior to the 1st decade contacts, and before the sign of the units is reached, the circuit will automatically change so that the plus on the Parallel contacts will disappear, and the ILI will be prepared to receive unit pulses; when you dial the mark of units, the brushes will make a corresponding number of steps and become on the line of the required subscriber. If the series of dests contained several HMnyvHbcOiB, then the searcher will run for several decades in the same way. At a normal subscriber disk speed, one pulse will last 100 ms, so that each of the five times of the run-through decade is 20 ms, i.e. the searcher must have a speed equal to 50 shch / s. With an accelerated disk giving 13 pulses IB second, the pulse duration is equal to -

Claims (2)

1. The method of controlling the forced motion of the step finders, characterized in that: in order to simplify the control devices of the motion of the searchers, the installation of the searcher's brushes on the required contact is carried out (in accordance with the decade numbering) by directly acting on the tenant and magnet pulse finder electromagnet, sent by a pulsed relay during the broadcast of pulses, so that the selection of a decade occurs when the searcher has a free run of several contacts, for example, four contacts during one bonentskogo pulse, and it was possible to work under ordinary searcher speeds by forming small decades into five, four or three contact - at the beginning of floor and containers decades bolschoy - & the end of the floor, and the breakthrough of the corresponding decade, was excluded due to the dependence of the last decade of the decade on the reverse attraction of the impulse relay at the end of the pulse. 2. The motion control method of the step finders according to claim 1, which is based on the fact that paired subscribers with individual numbers, but without individual contacts for each subscriber, are switched on by automatically switching the ringing current from one wire to another depending on the parity or oddness of the sign tenths of the number dialed.
