Abstract

The invention relates to interval control of train traffic in railway transport, in particular, to automatic locking. The invention improves reliability. The condition for switching on the enabling light at a traffic light is not only the operation of the main auto-blocking track relay, but also the train passing in front of the traffic light located. If, due to the poor shunt effect of the track circuit or for other reasons, false idleness occurs and the main track relay operates when there is a train in the block section, then by introducing two frequency track circuits, the traffic light from the busy block to the until the train passes in front of the traffic light and does not release the block of currents. 4 il.

This invention relates to interval Traffic Control for railway transport, in particular, to automatic blocking.

The purpose of the invention is to increase reliability.

FIG. 1 shows a rail scheme: line; in fig. 2 is a circuit for switching on the jBoro, the second and the third relay track control relays, and the memory relay; in fig. 3 is a scheme for submitting a notification to the previous signal installation; in fig. 4 is a circuit for activating a deletion relay. The device contains a frequency rail circuit with a track relay 1 with a contact li and a power source 2 connected to rails 3 on one side of the insulating joints 4, and on the other side of the insulation joints 4 there is a frequency rail circuit with a track relay 5 with contact 5i and source 6 power connected to the rails 7, the first relay 8 of the follow-up control with a contact 8i connected to another source 9 of the power supply through the rear contact 11 of the direct relay 1, the second relay 10 of the follow-up control from the contacts) lOi connected to I power source 9 through the front-contact contact 11 of the signal relay (not shown) and the contacts of the relay 8i and 5i, as well as the third follow-up relay 12 with contacts 12i-124, the capacitor 13 in the relay circuit 12, the linear circuit 14 with the power supply of the linear circuit 15, the announcer 16, connected by the line wires 17 to the power source in front of the lying signal installation (not shown), the memory relay 18 is connected to the power source 9 via the contacts of the third follow-up relay and the removal indicator 16i.

The device works as follows. In the absence of a train, track relays 1 and 5 of both frequency rail circuits are under current and their contacts b and 5i occupy the positions indicated in the drawing, and all the follow-up control relays are de-energized. After the train enters the pre-signal frequency rail circuit, the track relay 1 releases the measles and, via pin 11, switches on the first relay 8 of the follow-up control. Then, when the train enters the signal-frequency circuit, the track relay 5 is de-energized by its contact 5i at the moment when the signal relay has not yet been reset and its contact 11 is closed, the second follow-up control relay 10 is activated, which blocks itself through its end cycle 101 and remains energized after releasing the signal relay core. Finally, after the train has passed and the signaling frequency rail circuit is released, the track relay 5 is energized, which, with its contact 5i, during the deceleration of the second relay, e 10 of the tracking control, switches the current into the winding of the third relay 12 of the tracking monitoring. After energizing relay 12, it

its contacts 12i self-block at the time of discharge of the capacitor 13, and contacts 122 and 12z of the linear circuit 14 sends a current to the rear-mounted signal unit from the power source of the linear circuit 15 to energize the deletion message there and switches the memory relay 18 to the translated position. The translated memory relay contact excludes enabling light at a traffic light (not shown). After the train passes in front of the located traffic light, the devices in front of the installation are similarly operated and the removal announcer 16 is triggered in a linear circuit, which by its contact 16i switches on the direct polarity in the memory relay 18 and the latter throws the polarized measles into the normal position, thereby enabling the enabling fire at the traffic lights.

Thus, the condition for enabling the permitting light at a traffic light is not only the operation of the main auto-blocking track relay (not shown), but also the train passing in front of the traffic light located.

If, due to the poor shunt effect of the track circuit or for other reasons, false idleness occurs and the main track relay operates when there is a train in the block section, then by turning on the memory relay, the blocking light is safely fenced in by the red light until until the train proceeds ahead of the traffic lights and clears the area.
