FIG. 2

The invention relates to railway transport, and in particular to devices for transmitting information to a locomotive, and can be used in interval train control systems for subway lines.

The purpose of the invention is to increase reliability,

In FIG. 1 is a structural diagram of a device; in FIG. 2 is a schematic diagram of a control unit for closing the insulating joints.

The device comprises rail threads of one rail line 1 and rail threads of another rail line 2, a first signal unit 3 with a make contact 3.1 related to one rail circuit, a second signal unit 4 related to another rail circuit, a signal generation and transmission unit B automatic locomotive signaling, first b and second 7 matching blocks, insulating joints 8, block 9 of the connection of rail threads connected to the rails on both sides of the insulating joints, and the block 10 control circuit of the insulating joints.

Some outputs of block 9 are connected to the rail threads of one rail line 1, and others to the rail threads of another rail line 2. Two outputs of the block 6 are connected to the rail threads of the rail line 1 and two outputs of the block 7 to the rail threads of the rail line 2. The third output of block b is connected to the first output of block 10. The third output of block 7 is connected to the first output of block 4, the second output of block 4 and the first output of block 3 are connected respectively to the first and second control terminals of block 5, the first information output of which is connected to the second output of block 3 The second terminal of block 10 is connected to the fourth terminal of block 7, the third and fourth conclusions are connected to the third terminals of blocks 3 and 4, respectively, and the fifth terminal is connected via make contact 3.1 to the first control terminal of block 5, the second information terminal of which is connected with the fourth output of block 6.

Block 10 contains an input transformer 11 with windings 11.1-11.3, threshold elements 12 and 13 and actuating relays 14 and 15 with NC contacts, respectively 14.1 and 15.1.

One and the other conclusions of the first winding 11.1 of the transformer 11 form the first and third conclusions of the block 10. The outputs of the second winding 11.2 of the transformer 11 form the second and fourth conclusions of the block 10. The first 11.1 m of the second 11.2 winding of the transformer 11 are included

on the contrary, and the third winding 11.3 is connected to the first terminals of one 12 and the other 13 threshold elements, the second terminals of which are interconnected, and to the third

executive relays 14 and 15 are connected to the terminals. The fifth output of block 10 is formed in series with the disconnecting contacts 14.1 and 15.1, respectively, of relays 14 and 15.

0 The device operates as follows.

With the freedom of rail lines 1 and 2 in the case of a good condition of insulating joints 8 and the implementation of blocks 4 and 5 in

5, in the form of track receivers of the rail circuit, the signal current coming from the rail line 1 (the supply end of the rail chain is not shown in the drawing) is perceived by block 3, and the current coming from the rail

0 of line 2 is sensed by block 4. The signal current from rail line 1 enters through the matching block b also to the first and third conclusions of block 10 for monitoring the closure of insulating joints, i.e. in the first loop of winding 11.1 transformers, and the signal current from the rail line 2 through block 7 to the second and fourth terminals of block 10, i.e. into the second winding 11.2 of the transformer 11. From the third winding 11.3, a signal current is supplied to the inputs of the threshold elements 12 and 13 connected in series. The corresponding actuating relays 14 and 15, connected to the outputs of the latter, are connected to the supply, and

5 freedom of both rail lines.

This control is additional to the main one, carried out by signal blocks 3 and 4. NC contacts 14.1 and 15.1 respectively of the relay

0 14 and 15, the signal transmission circuit is open from the fifth output of the block 10 for controlling the isolation of insulating joints to the first control terminal of the block 5 for generating and transmitting signals of automatic locomotive signaling. In this case, block 5 generates a known logical

. automatic locomotive signaling (ALS) signal selection scheme depending on the train situation on the track

0 section into which rail lines 1 and 2 enter.

When one of the rail lines is occupied by a train, the level of insulating joints 8 decreases

55 of the signal current at the input of one of blocks 3 or 4 and at the inputs of threshold elements 12 and 13, Relays 14 and 15 are de-energized, by additionally monitoring the occupancy of the RC. When one closes

or two joints 8 with a free rail

lines for the signal current of both rail circuits are created in addition to the main transmission path (for one RC: block 6 - block 3 - block 10 and for the other RC: block 7 - block 4 - block 10) an additional path through closed cftiK 8 and block 9. This the path for one RC includes a circuit sold jointly by blocks 7 and 10, and for the other RC - blocks b and 10. By signaling the signal current of one and the other rail circuits along an additional path to the first 11.1 and second windings of the transformer 11 of block 10, the signal is superimposed RC itself, and since quipment 11.1 and 11.2 are included in the input circuit unit 10 with respect to each other oppositely, the total signal current in the third winding 11.3 coming from the same DC input to its threshold element (12 or 13) is close to zero. At a low input current level of the elements 12 and 13, the executive relays 14 and 15 are disconnected, connected to their output. Relays 14 and 15 switch their contacts 14.1 and 15.1 in the signal transmission circuit from the fifth output of block 10 to the first control terminal of block 5, closing this circuit,

Information about the malfunction of the insulating joints is sent to block 5, where, taking into account it, a control signal AL C is generated in accordance with the train situation relative to the front of the RC train located upstream. Thus, the proposed device, controlling the integrity of the state of insulating joints in adjacent rail circuits, generates an AL C signal for transmitting information to the locomotive.
