A disadvantage of this device is the possibility of obtaining false information, for example, if the contact system of the track relay is damaged. The purpose of the invention is to increase the reliability of the interpretation of code signals. The goal is achieved by the fact that the rear contact of the yellow fire relay, in series with which a resistor is connected, is connected in parallel to the winding of the green fire relay, the front contact of which is connected in series with the front contact of the latching relay and the switching capacitor, in series with the yellow relay winding The fire is turned off by the parallel-connected front contacts, the yellow fire relay, and the latching relay of the first pulse of the code signal.

The drawing shows devices for receiving decryption signals of a numerical code aBToOjioKH of an alternating current.

The rails 1 are connected to a throttle-transformer 2 journey. The device also contains a transmitter relay (not shown), through the front contact 3 of which one of the traveling choke-transformers 2 is connected via filter 4 and transformer 5 to an AC source (not shown) ).

The traveling choke-transformer of the adjacent track circuit is connected via receiving filter 6 to track relay 7. Through the rear contact 7 of the track relay, relay 8 is connected to fixing the first code signal interval with contacts 8.1, 8.2, 8.3 and 8.4. At the front contact 7.2, the relay 9 of fixing the first pulse of each code signal with contacts 9.1 9.2, 9.3 and 9.4 is connected to the power source via the rear contact 8.3 of the fixing relay of the first interval, in parallel with which its own front contact 9.3 is connected. Parallel to the winding of the relay 9, the latching of the first pulse included: the switching capacitor 10 - through the series-connected rear contacts 8.2 and 9.2; the relay 11 of fixing the first pulse of the code signal of its own track circuit with contacts 11.1 and 11.2 through the rear contact 12 of the relay of the repeater of the transmitter relay (not shown); relay 13 of green fire with contact 13.1, parallel to the winding of which a capacitor 14 is connected - through series-connected front contacts 8.4 and 9.4. Parallel to the winding of the relay 13 are also connected in series the resistor 15 and the rear contact 16.2 of the yellow fire relay. The switching capacitor 10 through two series-connected parallel circuits is connected to a yellow fire relay 16, parallel to the winding of which capacitor 17 is turned on. One circuit consists of parallel-connected front contacts 11.1 and 16.1, -a of one of the series-connected front contacts 8.1 and 13.1, in parallel which are connected in series connected rear contact 8.2 and front contact 9.1.

A device for decrypting numeric code signals operates as follows.

If there is a train in the block section protected by a traffic light, the measles of the relay relay 7 are in a no longer state, the fixation relay is de-energized and the light) Ore a red fire burns. When releasing the block, a numerical CR signal with a single pulse starts to arrive.

cycle. During the pulse, the relay 7 is activated and through the contact 7.2 it closes the power supply circuits of the relays 9 and 11. At the same time, the capacitor 10 starts charging, as the relay 9 has a deceleration response. After the operation of the relay 9 / its contact 9.1 connects the capacitor 10 to the winding of the relay 16 and the capacitor 17. After arousing, the relay 16 turns on at a traffic light

Q yellow light, in the intervals between the pulses of the code signal, release the core of the relay 8.9 and 11, and the relay 16 keeps its core pressed by the discharge of the capacitor 17 to its winding.

 During the reception of the code signal with two pulses in the cycle, at the first pulse the capacitor 10 is charged, the relays 9 and 11 are triggered and the capacitor 17 is charged. In the first small

0, the relay 8 is energized, with the second pulse the power supply circuit of the green fire 13 and the capacitor 14 closes. When the second pulse is received, the relay 8 is self-locking

5 (the front contact of the relay 8 connects the coil of this relay through the contact 11.2 to the power source (not shown in the drawing).

When receiving a code signal with three Q pulses in a cycle with the first two pulses, the circuit will work in a similar way. When the third pulse is received, the power supply circuit of the relay 13 and the capacitor 14 will close in compliance with 9

 Same conditions as in the second pulse. Excited signal relays 13 and 16 turn on green light at a traffic light.

In case of stopping the power supply of the track relay 7, the relay 9 de-energizes

0 and after the discharge of the capacitor 17, the measles of the relay 16 disappears, which leads to a prohibitory indication of the traveling light.

The scheme provides zaitsita from

5 occurrences of yellow fire instead of red at the output traffic light, with the first removal area occupied in case of mechanical damage to the contact system of the track relay.

П At simultaneous closing of contacts 7.1 and 7.2 of the track relay, relays 8 and 11 operate in the pulse pair mode, relay 9 is not energized, since the total response time of relays 8 and 11 is shorter than the pull-down time

Claims (1)

relay 9, This leads to the charge of the capacitor 10. In order to exclude the possibility of its discharge on the capacitor 17 and the excitation of the relay 16, the frock contact 13.1 of the green fire relay is switched on in series with contact 8.1. During normal operation, pin 13.1 does not interfere with the decoding algorithm for 1dh signals, since capacitor 17 receives power from capacitor 10 at the first pulse of the code signal via contact 9.If and at subsequent pulses through 8.1 and closed front contact 13.1. The scheme excludes the appearance (glimpse) of yellow fire instead of red. During a short circuit in the insulating junction and occupied a block section. When a traffic light passes through a single locomotive with high speed and moves it a certain distance away from the code signal pulses of the adjacent rail circuit, the track relay 7 and the relay 9 will work in a pulse mode, the relay 11 will be opened by contact 12 of the excited relay to repeat the transmitter relay bodies, therefore, the circuit of the relay 16 and the capacitor 17 will be interrupted by the contact 11.1. Upon normal reception of the code signals, the relay 11 is energized and creates a circuit for the operation of the relay 16, after which excitation the contact 16 ..1 shunts the contact 11.1 and the power supply circuit of the relay 16 and the capacitor 17 is not interrupted. The scheme provides protection against the occurrence of green fire instead of yellow for a short block-section and following it with a single lox with a high speed. The proposed device automatically corrects disturbances in the normal mode of decryption in case of inefficiencies of the circuit elements and eliminates the dependence of the alarm on the busy time and the block size.
