Description

The invention relates to railway automation and telemechanics, namely to rail circuits,

The purpose of the invention is to improve reliability,

The drawing shows a schematic diagram of the device.

The device contains code track transmitters (CPT) 2 and 3 connected with each other and with one pole of voltage source 1, CPT 2 is connected to the output, and CPT 3 is connected to outputs a, b, c. The output of the latter is through the serially connected closing contacts 4 and 5, respectively, of the linear signal relay and the signal relay of the output traffic light of the same path (the relay is not shown), in parallel the connected closing contacts 6 and 7, respectively, of the switching-off relay of one MapujjiyTa of the departure and its receiving and return path ( relays not shown), the winding of the transmitter relay 8 of one route -, Q dispatch, is connected to the other pole of the voltage source 1 connected in series with the winding of the transmitter relay 9 of another ma the sending route, parallel-connected closing contacts 10 and 11, respectively, the co-switching 25 relays of the other marafuta of the sending and its receiving route (the relay is not shown) by the closing contact 12 of the signal relay of the output traffic light of another way (the relay is not shown), pinned by contact point 5 and 4, The contacts of the latter are connected to the output b of the code track transmitter 3. The device also contains an arrow code-switching relay 13 with a contact 13.1 of the arrow section adjacent to the receiving port. M, the closure, the contact of which is connected with the output of KPT 2, and disconnecting - to the output of KPT 3, the turnout switch-on relay of 14 switch sections of the sending route, one output of the winding connected to one pole of the voltage source 1, and the other through parallel-connected disconnecting contacts 15 and 6 of the traveling relays, respectively, of their own and the previous switch sections (not shown) connected to the other pole of the voltage source 1. In this case, one output of the winding 45 of the relay 13 is connected to the source 1, and the other through the disconnecting contact 17 of the actual track relay (not shown) - in series with the closing contact 15,

The device works as follows.

When specifying the route of the route from the single path and the serviceability of the insulating joints between the receiving and return section and the switch section, contacts 6 and 7 of the codec

When the relay is closed, contact 5 of the relay relay is also closed. Depending on the position of contact 4 of the linear signal relay, the transmitter relay 8 goes to output a or b of the code tracker smitter 3 and begins to repeat these transmissions to the rail circuit, the train is not on shipped to the shipment.

Another train, standing on the other in front of a closed traffic light, is obtained from the exit to the code track 3,

When the train head enters the exact section adjacent to the tracks, the track relay of this section is shown) and its contacts 17 are closed, the connecting p and 14 of the arrow section and the adjacent section are initiated. The coding to the sending-out routes begins, and the adjacent coding is pressed with

When energized to before switching on 13 and closing its contact 13.1, the second path begins to arrive from the track transmitter 2 through the output. This code has a single pulse with a duration of 1, 2 s and an interval of 0.4 s. Butt short circuit occurs, the head of the driving train finds an arrow switch. the section adjacent to the codes for this train, by shifting the undistorted code, does not cause this code either. Therefore, the train, one hundred times lateral, does not receive a false one.

When the head of the train goes to the section by contact 5 of the track section of this section, the power supply of the coder relay 13 is cut off and the circuit is not closed with the code switch of the adjacent relay 14. Then, along the route, turn on the sections for which the entire head of the train is turned off, and the coding is turned off for the sections along which the heading has passed. The coding of the other path by the unresponsive code is stopped, resumed, the coding from code tracker 3

If there is a short circuit by means of the acceptance and the inner section before starting to rotate or after the train passes, the track relay of the arrow section closes its contact 17, the switching relay 13 is triggered, and contact 13.1 is triggered. Begin by coding another path with undistorted code. It is held until the damage is eliminated1 and

When the relay is closed, pin 5 of the signal relay is also closed. Depending on the position of pin 4 of the linear signal relay, the transmitter relay 8 is connected to output a or b of the code track transmitter 3 and begins to repeat these codes, passing them to the rail circuit on which the train departing by departure post.

Another train, standing on a different path in front of a closed traffic light, receives codes from the exit to code track transmitter 3,

When the train head enters the stretch, exact section adjacent to the tracks, the track relay of this section (not shown) is de-energized and its contacts 16 and 17 are closed, and the switching-on relays 13 and 14 of the arrow section and adjacent to it are energized. The coding of the section adjacent to the receiving points begins, and the coding of the adjacent section is prepared.

When energized to before switching on relay 13 and closing its contact 13.1 to another path, it begins to come from code track transmitter 2 through output a code. This code has one impulse with duration of 1, 2 s and an interval of 0.4 s. If a joint short circuit occurs when the head of a moving train is located on the switch section adjacent to the track, the codes for this train, shifting with the undistorted code, do not cause a change of this code. Therefore, a train on the side track does not receive false information.

When the head of the train goes to the adjacent section by contact 5 of the traveling relay of this section, the power supply of the coding relay 13 is cut off and the power supply circuit of the coding relay 14 of the adjacent section closes. Further along the route, coding is turned on for sections where the head of the train enters, and coding is turned off for sections through which the head of the train has passed. The coding of the other path by the undistorted code is stopped, the coding from the code track transmitter 3 is resumed, 1

If the joint is short-circuited by the dressing unit and the switch section before it starts driving along the Mapuj Route or after the train passes, the track relay of the switch section is de-energized and its contact 17 is closed. As a result, the switching-on relay 13 is activated and contact 13.1 is closed. The encoding of the other path begins with an undistorted code. It continues until damage and the joint are eliminated (the track relay of the section is de-energized)
