Description

There are central telegraph points that transmit telegrams to other stations, receiving from the latter nothing but brief conditional signals. Usually, such stations still have full duplex equipment, and all the transmitting equipment at the receiving stations and the receiving device / transmitter at the transmitting station are idle, rotating only for the possibility of pereboron or some brief request. The latter increases the cost of such installations and complicates their maintenance. By using the one-way wiring method proposed according to the invention using the conventional duplex wiring scheme, it is intended to eliminate the disadvantages mentioned above.

The drawing shows a diagram of an apparatus for carrying out the proposed method.

At the transmitting station, only half of the so-called set of normal equipment of a particular system is installed, i.e. only one transmitter (transmitter), duplex device (relay 1, 2, rheostat 3, capacitor 4 and signal lamp 5) or clopfer with automatic device for stopping the transducer

host station. At the receiving station C, only one skorostyuyushchy direct-typing receiver b and Morse key 7 is installed. No linear battery at the receiving station is required, since the work is carried out according to the Morse mode of operation on the so-called "direct current" that goes into the ground. Work under these conditions proceeds as follows. The currents of the transmitter of the transmitting station are divided, as in a conventional duplex, in a linear differential relay 1, 2 (or galvanometer) into approximately two equal parts. One part goes through one winding 2 relays 1.2 into the wire and along the wire to the receiving station, and the rest through the second winding 1 relays 1.2 and rheostat 3 of the artificial line to earth. Just as in the normal duplex, a balance is chosen, but the balance is not between the incoming and outgoing currents, but only 1) Ko between both branches of the outgoing current, i.e. between the current branching into the telegraph line and the current branching into the artificial line. This balance is chosen very roughly (a difference of two to three thousand ohms is allowed), 9 by only calculating that the relay only reacts for a wire break or for a sharp increase in eijo resistance. The relay relay circuit at the transmitting station includes either one of the poles of the line battery 8 in series with the lamp 5 (ring or clop) and a solenoid, or a special battery can be included. At the receiving station, the Morse key 7 of the normal type is connected in series with the receiving circuit to the line circuit. With

Under such conditions, during normal operation of the transmitter and with Morse closed at the receiving station, the outgoing currents of the transmitter have no effect on the measles of their linear relay, and it remains at idle contact. In this case, the circuit of the signal lamp 5 and the solenoid 11 remains open, and the rod of the latter is lowered. Together with the solenoid rod, the locking lever 9 of the transmitter, which in this position does not prevent the rotation of the mechanism of the latter, is also lowered.

As soon as the receiving station with | One goal or another (interruption, call, conditional signal, etc.) will lift the Morse key knob up and thereby open the wire circuit - now the transmitter currents of the transmitting station rush almost entirely into the artificial line through the second winding of the relay. Under the influence of these currents, the bark of the relay 1.2 will begin to reproduce all the work of the transmitter of the transmitter 10 and will begin to touch the working contact of the relay. The circuit of the first signal lamp (or klöpfer) and the solenoid will close and open in time with the operation of the rotator. Thanks to this, the first lamp will start flashing or clapping sound, or the bell will ring.

At the same time, when you first touch the relay to the working contact, a solenoid of 11 volts no rod p snaps into place

him, dog 12, which will block him in this semi-tendency. At the same time, the rod of the solenoid 11 will drag the lock lever 9 of the transmitter behind itself, stop the latter and, pressing its upper end on the spring contacts of the second signal lamp 13 (or bell), will close it. From this point on, the second lamp will remain on until its

- do not turn off with a special switch (not shown in the diagram), or until the rod of the solenoid 11 is released from the holding pawl. Thus, the interruption takes place and in this way a random break of the wire or any accidental damage to it will be noticed. After the transmitter is stopped at the transmitting station, the receiving station, using the energy of the latter, may, using a klöpfer, bell, lamp or Morse apparatus, negotiate with the transmitting station using the “direct current” method.

The presence of a solenoid is necessary only in cases when several people are watching one transmitter. In this case, the rolenoid locks the transmitter just at the interruption. When it is excluded, the request „that it is repeated to the corresponding answer at the iiero receiving station. In the same cases, when each transmitter has a special supervision, neither a solenoid nor a second lamp is needed, since the first lamp will give a fairly clear interruption signal and the transmitter can be stopped by hand.

A method of one-sided wiring with skorostyuyushchy direct-printing apparatus using

a conventional duplex telegraph scheme for sending call backs and interruptions, characterized in that, in order to use only one of the two sets of equipment necessary to operate in two directions, and to use for transmitting the call signals and the Morse key, the differential transmitter is equipped with windings 1 and 2, of which winding 1 is grounded through an artificial line, and winding 2 is connected to a line operating with the sending of call back signals and with a Morse switch according to a direct current circuit, The relays of which relay are used to close the solenoid circuit, the rods of which are connected to the transmitter's stop lever - to stop the latter and to close the contacts of the signaling lamp circuit.
