Description

one

The device can be used, for example, to simultaneously transmit several AC electrical signals over a single two-wire line or over a single-wire using ground as a return wire.

A device for transmitting sealed electrical signals is known, comprising channel kits consisting of a source of information signals, two ring-shaped ferromagnetic cores with windings, an electric filter and a high-frequency oscillator connected to one of the windings.

The purpose of the invention is to expand the functionality of the device.

The proposed device is characterized in that three windings are applied to each core and the generator output is connected in series with two windings connected in opposite directions, one of which is applied to one core and the other to the other; the source of information signals is connected in series with the electric filter and two according to the windings connected between them, applied to the first and second cores respectively, the output (input) windings are also applied to the first and second cores and connected after the windings (in ts-1 1 according to, and the windings are individual channel connected in series between CG6oi i, with the communication line and with the input windings of the channel sets.

Lia drawing shows a functional diagram of the device.

Set paiCiBo cr der / kit winding 1-6 for information signals, high-frequency generators, electrical filters 3-18, ring-shaped ferromagnetic cores 9, pyhol:; y (input) windings 20-25.

When signals were not transmitted from –A to B 23, 24, 25 c.1.:; 01c with input signals, and at reverse: to transfer - to 1 input.

The windings are applied to the cores 19 in such a way that when there is a signal on the winding 1, 2 or 3, there is also no signal on the output winding connected to the line, since the emf induced by the generator 7, 8 and 9 in the output winding of both heartbeats, mutually equalized, AST. When a signal arrives at winding 1, 2, or 3, a second harmonic of a high frequency generator arises, modulated by an INHI SDS11M signal.

The frequency / ;, / ,, and} d generators 7-9, forming a series in accordance with the selected frequency values for compaction of the connecting line, must differ between co6oi i and coincide with the frequencies fio, / 11 and fi2 of generators 10-12 .

With simultaneous postunlenin in the windings 1-3 of the input information signals with frequencies FI, / 2 and / s in the output windings 20-22 of the corresponding channel devices interconnected consequently, the second harmonics of the oscillations of the corresponding generators 7-9 modulated by the input signals i &; ± p2,

.

Thus, the information signals supplied to the windings 1-3, in the windings 23-25 of the receiving sets, generate signals with frequencies equal to twice the frequency of the generators 7-9 modulated by the frequencies of the information signals.

The windings of the cores of the short sets are oscillated from generators 10-12. As a result of the interaction of magnetic fluxes in the input windings 23-25 and in the power windings in the output windings 4-6, due to magnetic detection, oscillations with the frequencies of the information signals FI, F and / j are separated, respectively.
