Description

The invention relates to railway automation and telemechanics, in particular to track circuits, which provide distance control and traffic safety of trains.

The purpose of the invention is the increase in reliability.

The drawing shows a functional diagram of the proposed device.

The device contains track relays 4 with contacts 4.1, 4.2 and 4.3, relays 5 with contacts 5.1, 5.2 and 5.3, relays 6 with contacts 6.1 and 6.2, relay 7 fixing the last car, trains with contacts connected to rail lines m 1, 2 and 3. 7.1, 7.2 and 7.3 of the rail line 2, the switching contacts 8 and 9 of the latching relay of the last train car (not shown) respectively 1 and 3 rail lines. Relay 7 is connected to power supply 10 via contact 5.2 of track relays 5 of its rail line 2 and in parallel through its own contact 7.2 and relay 4.2 of relay 4 connected in series with each other. Coding blocks 11, 12 and 13 are connected to the outputs of track relays ahead of lying rail lines and output - with one input of the corresponding translation switches 14, 15 and 16, the first and second outputs of which, formed respectively by contacts 7.1, 8, 9 of the latching relay of the last train car, are connected respectively to ONE end of their the rail line and another input of the translation commutator of the previous eleven rail line, and the other input of its translational switch is connected to the second output of the translational switch of the next rail line. Relay 17 for fixing the approach of trains with contacts 17.1 and 17.2 is connected to the power source 10 via serially connected own contact 17.2, contact 18 of the relay for fixing the approach of trains of the previous route line (not shown), parallel-connected contacts 7.3 of relay 7 and 4.3 relays 4 and connected in parallel with them. consecutively connected contacts 5.3 relays 5 and 6.2 relays 6, while other contacts 17.1, relays 17 and contacts 17.3,17.4 of the train locking latching relay are included in the corresponding translational switches in series respectively with contacts 7. 1 relay 7. re. 8 and 9 relays fixing the last car of the train of rail lines 2, I and 3.

The device works as follows.

Each rail line is equipped with the same set of equipment, which is fully shown for rail line 2. In the initial state, when within rail lines. 2, 3 there are no trains, all the nutev relays 4, 5 and 6, all of the fixing of the last carriage of the train and all the relays of fixing the approach of trains are energized. Rail lines do not receive code signals, since for: they are OTcyi

closed circuits from coding blocks.

In the case of the passage of a single-seat train, the corresponding track relays and the latching relay of the last car of the train are de-energized, and the coded signals enter the rail line within which the last car of the train is located. So, when a train enters the limits of the rail line 2, track relay 5 is de-energized. Relay 7, despite the opening in its contact circuit 5.2 of track relay 5, remains under current through the self-locking circuit through its own contact 7.2 and 4.2 of track relay 4 of the previous rail line, that train. In this position, the transmitting switch 15 translates the code signal from the second output of the transmitting switch 16, to which this signal comes from the output of coding unit 13, to the second input of the transmitting switch 14. From the outputs of the latter, depending on the location of the train tail, the code signal goes either to the rail line 1 is either broadcast further. When in the process of movement the train releases the rail line 1. relay 7 is de-energized, since its second circuit will be open by pin 4.2. In the transmitting switch 15, contact 7.1 cuts off the signal to the second input of the transmitting switch 14 of the previous block; Open relay 7.1 of this relay connects the current flow circuit of the code signal to the input end of the rail line 2. Transmit the code signal to the rail line 2 from one of the coding blocks in front of the rail located. Piniy will continue until the train releases the rail line 2. Then through the lock} contact 5.2 of the track relay 5, relay 7 will energize and with its contact 7.1 it will disconnect the rail line 2 from the coding units afterwards from their slides1 | to the lines. With the passage of a single train, the S7 relay fixation of the approach of trains remains continuously under current, since its first supply circuit is constantly maintained.

If there are other trains on the line section before the first train, then the wave is turned off on the transmitting circuits of switches 15 and 16. The transmission of the code signal stops on the rail line 2. If the second train completely moves to the rail line 2, then go to - still no code signal will be transmitted, if now both trains will move one after the other further so that there will be no free rail lines between them.
