The purpose of the invention is to increase the reliability of the device. *

The drawing shows a block diagram of a device.

The device contains a two-wire line 1, in which the control relay 2 with contacts 2.1 - 2.9 and the control relay 3 with contacts 3.1 - 3.7 are connected in parallel on the stage, and the emergency relay 4 of alternating current is installed at the station, through '4.1 which its reverse repeater 5 is connected , through terminal 5.1 of which a DC source 6 and buttons 7 for switching on control relays are connected to the line, connected in parallel with terminal 5.1; to rail lines 9 * ~ 11, limited (by insulating joints 12 and 13, on one: matching blocks 14 - 17 and additional pulse relays 18 with pin 18.1 and pulse relay 19 with pin 19.1 connected to decoders 20 and 21 are connected from the ends the output of which includes additional track relays 22 with contacts 22.1, 22.2 and an additional track relay 23 with contacts 23.1, 23.2, respectively, and at the other end of the rail lines they are connected to a pulse relay 24 with contact 24.1 and a pulse relay 25 with contacts 25.1 and matching units 26 and 27 to which sub the alternating current source 28 - 30 is switched on, while the trip relay 31 and 32 with contacts 32.1 - 32.4 are connected to the decoder 20 and 21, which are connected to a linear circuit 33, at one end of which a linear relay 34 with contacts 34.1, 34.2, 34.3 is connected and a repeater of the linear relay 35 with contacts 35.1, 35,2 at the same end of the linear circuit is connected / relay 36 monitoring the drive with contacts

36.1 and 36.2, and at the other end of the Line circuit the contacts of the fire relay 37- and the contacts of the repeater of the linear relay and 42 (the relays themselves are not shown) are connected, while the fire relay 46 is connected in series with the traffic lights 43 45

46.1 and 46.2 connected to the transmitter

47, which in turn is connected to the transmitter relay 48 and its contact

48.1, connected to the same rail line, and the contacts of the transmitter relay 49 and 50 are connected to the other rail line and to the decoder (the relay itself is not shown). ___

The operation of the device for interval regulation of the movement of trains proceeds as follows.

In the presence of alternating current in the power supply line, the alarm relay 4 is under current, and its reverse repeater 5 is de-energized, contacts 5.1 are disconnected from the two-wire line source 6, as a result of which the control relays 2 and 3 are also de-energized. By the contacts of the control relays 3.7 and 2.8, 2 ^ 9, a block 27 is connected at one end to a block 27 and at the other end to a block 16. On adjacent rail lines, a block 26 is similarly connected at one end, a block 17 at the other end. The contacts of the transmitter relay 48.1 and 49 send pulses of a numerical code to the rail line, depending on the train situation, which is determined by the relay contacts 22.2 and 36.1. Using these contacts, the transmitter relay 48 is connected to the transmitter 47. The pulses sent to the rail line by the contacts of the transmitter relays are received using additional pulse track relays 18 and 19. Using decoders 20 and 21, the pulse operation of the relay contacts is decrypted.

18.1 and 19.1, as a result of which the underflows of relays 22 and 23, connected at the output of these decoders, arise. The contacts of these relays in the linear circuit 33 is supplied with alternating current from the source 30, signaling about free ™ in front of the lying block of the site. AC signal drives a relay

36. connected via the contacts of the monitoring relay 2.3 and 2.4. which turns on with its contact 36.2 a green light lamp 44 at the passing traffic light, as well as with

36.1 connects the transmitter relay 48 to the green light washer, transmitter 47. As a result, the green light code combination is sent to the rail line 9.

When AC is disconnected, alarm relay 4 releases its armature and, by contact 4.1, turns on its return repeater 5, which in turn, by contact 5.1, connects a DC 6 source to two-wire line 1. As a result of connecting source 6, control relays 2 and 3 are activated. relay contacts 3.4 - 3.7 and

2.6 - 2.9, the matching blocks are switched, connected to the rail line 9 - 11. Blocks 14.15 and relays 24 and 25 are connected to the rail lines 9-11. Through the block 14, DC pulses are sent to the rail line, which are received by the relay 25. С using the decoder 21, the pulse operation of pin 25.1 is decrypted, and the relay 32 is activated at the decoder output. Track relay contacts -

32.1 and 32.2 connect a direct current source to the linear circuit 33 through the contacts of the linear relay 41, 42 and the fire contacts 5 of the relay 39 (the relays themselves are not shown). At the same time, at the other end of the linear circuit, a linear relay 34 is activated and turns on its repeater 35. The contacts of the linear relay and its repeater 35.2 and 34.2 turn on the Lam-10 pa 44 green light at the passing traffic light, and with contacts 35.1 and 34.3 the coil of the transmitter relay 48 is connected to the washer green light transmitter 47.
