SU79649A1 - Device for automatic control of telegraph channels - Google Patents

Description

The invention provides for the possibility of automatic monitoring of channels telegraph | oh communication.

The proposed device for automatic control of a telegraph communication channel indicates a deterioration in the operational state of the line before signal distortions exceed the available value, while the so-called line health probes used so far cannot provide such signaling.

Distinctive features of the proposed device are:

a) the use of a distortion indicator for the constant monitoring of telegraph channels, connecting pa determining periods of time (about 15 seconds) to the controlled carp: there by means of a continuously rotating step finder;

b) the use of signal relays (one each. each dripped), connected in turn to the output of the HH / UiKaTojia and blocked at the distortion, and exceeding 1, their set points;

c) applying a resolution circuit consisting of three relays to turn on a pulsed circuit in the electrically driven magnet to turn on the distortion indicator signal circuit at the switch time of the searcher and the time it enters the phase, and also to prevent the distortion indicator from being connected to inactive and faulty channels;

d) the use of a resolution circuit consisting of one polarized telephone delayed relay, in order to close the signal circuit of the indicator when pressed in a controlled channel.

Soup; the invention is illustrated in the drawing, which shows a diagram of the proposed device.

No. 79649-2 -

The device consists of a distortion indicator, a step-by-step detector, alarm devices, a relay, etc.

The searcher M is approached with compacted lines connected in parallel to the station jacks of the local switchboard of the line equipment room. In this case, only receive chains are supplied. A 15-pin 1 searcher is used (actually - and the op has 17 contacts) to which all 16 channels of one telegraph communication system or any other channels operating on start-stop equipment can be brought to control.

The first rm.h-4 iskat.1 And included control lamiy L, -Lz;, which, by the way |. The lights indicate which channel in the Daini MOMeirr controls the device.

The second row B is used to turn on co-controlled channels, which are connected via a finder through the searcher to the input (terminals 1 - 2) of the distortion indicator.

Switches Tj) eTbero p / yes Intended for switching on the circuit of the pulse relay PR on the winding of the winding of the echomagnet VE for the iie searcher to be delayed in those positions which correspond to the language of the channels, in order to avoid unnecessary loss of time ; using the distortion indicator.

The pins of the fourth pt. G are used / Chip of the inclusion of sigpa, of the first circuits of the gribrior.

Relay R; R ; Рщ; and, not for all 16 channels; relay one for each channel; impulse device // At and pulse-relay .G / I - common on a rack of control devices. As a pulse, ycTpoiiCTBa can also be used a device for handing time signals (one for the entire linear equipment room), used in counters for calls and time in automatic telegraph stations.

The proposed ycTpoiiCTBo works as follows.

Pulses with a duration of 1 - 1.2 seconds are fed to the winding ale P from the clamp /. at intervals of 15 seconds. from a pulsed IC device. Pulses from the same ycTpoiicTBa with an interval of 15 sec. But shifted in time n; i 5 sec. from pulses in the windings of the relay R.

When a pulse arrives at the relay P, its Koptak L 3 and 4 are closed by 1–1.2 sgch -., Sending a 1 p pulse to the rotating electromagnet of the explorer. Springs 5 and 6 open, interrupting the contact circuit of the common PIV alarm relay to turn off the PA 1 alarm; remi rotate the search to avoid spurious signals. The springs / IU-switch closes, forcing;) The Rsch relay operates, which is blocked through its contacts 3 and 4 and the RP relay contacts. Contact, 1 and 2 Pni relays open the alarm circuit so that the 1 1 distortion indicator forces to enter the phase with working sigpa. It comes IT1MP to its input from cogg: 1 circuit that is through the springs of the CL-key, and the contact of the second yes. According to research m: pdpk; the torus enters the phase during no more than 2.5 seconds. ispn auto; operation of the transmitter, io, for the sake of reliability and idle time, the switch-on time of the instrument's sigle value is increased to 5 seconds When a pulse arrives at the winding of the relay Rc (the pulse follows five seconds after the impulse is inserted into the winding of the relay PI), the blocking circuit of the relay Rsch is closed, therefore, its coils 7 and 2 are closed, iodgote; .) Pogo (ie; ie PI through kotkakty} barely Pu and P),

If the distortions of the signals do not exceed the norm, then the current pulses in the Signal target of the nciar-KeiiiiH indicator (plugs 3 and 4) are absent, the PIV relay does not work, and the next, plus the messenger battery, Jo cannot reach the brush1; yes seeker through contacts 5 and 6 of relay P; and contaggs / i. 2 relay RPG Therefore, the relay of the channel that is in the current;,: ohm: g. is controlled by the device, it can not work, it is red c; ir:; a; j.; ah the lamp C // i (red) does not light up and, accordingly, the general signaling is not working (common signal light OSL and zonioio .; .Jfi) .

In case of distortion, exceeding the norm, the relay Piv is triggered and turns on the windings of the relay P; if the first channel is controlled at that moment. The triggering, pe.ie PI is blocked, following:; ate, tio, the signaling continues even when 1C ;;;; Tel comes off the first COI; of the act. Hjin ztol closes the circuit. CJ / j (red) indicating the dead channel has died, the circuit is closed, the sigpalzapia (OMS / and 3s) is closed.

The damage signaling price remains closed until the CL key, ne is nocTai3; ieii is switched off, then the relay P releases, the red warning light goes out and the SL (yellow) lamp lights up, the pointer is dropped verification.

For a closed circuit: cd1; cat ()): 1, when a circuit was applied in a controlled channel, a time scheme was used. consists of one g polarized slow-motion PV relay.

If there is no work in the controlled circuit, the relay's measles lie at the left-hand contact, therefore, the PV relay is pulled. When working at the moments of transfer of the PVI relay core, the delayed relay RK does not have time to release its co-switch. iip-i iazhatii on the channel of the PV relay releases the measles, the closure at the same time the current circuit through the windings of the PIV relay: plus 120, the relay contacts, the winding re. Relay Р-у will work, no ceoii measles and will cause the alarm device to be activated for him as it is; a.

In the diagram, the letter K is indicated by an additional contact.

The subject is invented and.
