The invention relates to railway automation and telemechanics, namely to automatic locomotive signaling.

The purpose of the invention is to increase reliability.

The drawing shows a schematic diagram of the proposed device.

The device has a relay 1 fixing the end of the train with two closing 1.1 1.2 and one opening 1.3 contacts, a relay 2 fixing the train connection with two closing 2 1-2 contacts, 2 track relays 3 for 5, 3, contact and 4 with two disconnecting contacts 4.1-4.2, respectively, of rail sections 5 and 6, a generator of 7 code signals, a relay 8 of fixing the end of the train for contacting them with contact 8, and a disconnecting 8.2 and 8.3 relay 9 of the closure of trains section 6 with closing contacts 9.1 and 9.2, and the generator 7 code signals connected to section 5 via the It is connected “11e contacts 1.3 relays 1 and to 2si time relay 2, winding through contact 1e1 relay 1, in parallel with which are connected serially connected own contact 2.2, closing contact 8.1 relay 8 fixing the end of train section 6 and one of the closing contacts 9.1 of the relay 9 for fixing the approach of trains of section 6 (the circuit Nfti for connecting the relays 8 and 9 are not shown) is connected to the power supply 10 and parallel to the contacts: 8.1 and

9.1. 4.1 and relay 4 are switched on. Relay 1 is connected to source 10 by connecting via relay 3.1, relay 3, in parallel (with which are connected sequentially contact 1.2 of relay 1 and contact

4.2 relay 4, connected in parallel with one of the break contacts 8.2 of relay 8, through another opening contact 8.3 of which and in series with it another closing contact 9.2 of relay 9, the generator 11 of the code signals of section 6 is connected to the rails.

The device works as follows.

In the initial state (in the absence of trains), relays 1-4, 8 and 9 are under current and the coding of sections 5 and 6 of the rail line is not carried out due to the open state of the contacts, 3 relays I and 8.3 relays 8 in order connecting generators 7 and 11

Accordingly, when the train enters the rail line section 6, a track relay 4 is provided which, with its closed contact 4.2, collects a relay 1 circuit of fixing the train end of the rail line section 5. As the train advances and the tail wagon of section 6 of the rail line de-energizes the relay 8 fixing of the train end and, in addition to contact 4.2, organizes a blocking circuit of relay 1 with its closed contact 8о2. When the train enters the section 5 of the rail line, track relay 3 de-energizes and after opening its contact 3.1 Relay 1 receives power only through the blocking circuit. After the train has opened the rail track section 6, its track relay 4 will be energized and relay 8 will be energized. From the moment of opening of its contact 8.2 to NOSTA disassembled lockup relay circuit 1. Thus, de-energized, it is only checked s freeness portion 6 of the rail line, but the lack of fixing on it the end of the train. From this moment on, relay.2 fixation of the approach of trains receives power through the blocking circuit from the already pre-closed contacts 2.2 5 9.1 and 8.1,

When the second train enters the section 6 of the rail line, its track 4 relay is de-energized. Its closed contact 4.1 creates an additional connection in the blocking circuit rel, e 2 fixing the approach of trains to the power supply 10. As a result, it continues to receive power even after the tail car of the second train ends up within section 6 of the rail line and relay 8 is de-energized by opening its front contact 8 in 1 in the blocking circuit. The release of the relay 2 for fixing the approach of trains occurs only after the track line section 6 is released by the tail car of the second train that continues to approach each other, when the track relay 4, having turned on the current, opens its contact 4.1. Since the relay In the train tail fixation of the previous rail track section 6 has not yet been energized and its contact 8J is not closed, the blocking circuit of the train fixation relay 2 is open in two parallel branches with terminals 4.1 and 8.1. During the flight time, the train approach locks. As a result, the blocking pitch of this relay is finally disassembled by its 2.2 opening, and coding of the rail line section 5 is not allowed due to the open state of contact 2.1 in the generator 7 output circuit,

cycles of the track relay 4 and the excitation of the relay 8 of the relay 2 of fixing the approach of trains manages to release its measles and the open contact 2.2 finally opens the blocking circuit, completing the fixation of the approach of trains on the rail track section 5. At the same time, the open contact 2.1 prevents the sending of code signals from

generator 7 into the rail line in the zone) 0 Formula of section 5, Relay 2 is activated by fixing the approach of trains after the section of the rail line 5 is released, when its track relay 3 and fixing for the end of f5 Ca of the train and the approach of trains , high relays and code signal generator The relay fixation relay 9 works in a similar way. In the event that they already have a convergence of trains, and these trains are about the 20th end of the train, one of the closing trains is a joint movement, the transfer of the tacts of the fixation relay of the train approach to the next section 5 of the rail line (relative to section 6) occurs

in the following way. When lane-25 enters, another of its own closed loops are connected along the following contiguous trains in sections 5 of the rail line and track relay 3 is de-energized. As a result, the end fixing relay 1

trains receive power only through 30 to the power source to which the blocking circuit, and relay 2 of the fixation relay of the end of the train approach train –– through contact 1.1 of relay 1 of the end of the train and through the blocking circuit of its own through the closing contact the track relay of its own rail section, connected in parallel with the subsequent contact 2.2 and contact 4.1, which are consistently connected with their own teh relay 4 of the previous section 6 of the rail line, since the front contact 9.1 sled relay 9 and the relay contact 8,1 8 open. After the release of 40 by the second of the converging trains of section 6 of the rail line, the track relay 4 is energized. Its open contact 4.1 provides the end with another closing contact and one of the trip contacts of the track relay of the previous rail section, characterized in that to the power supply circuit of the relay fixation of approaching trains in series with another own closing contact and closing contact of the terminal fixing relay
