The invention relates to the transmission of information by rolling stock of railways and can be used for the operational control of the operation of rail transport.

The purpose of the invention is to increase credibility.

The drawing shows a block diagram of a device for transmitting information about the rolling stock of railways.

A device for transmitting information about the rolling stock of railways contains, at a recording point, a sensor 1 for detecting wheelsets connected via counter 2 to a decoder 3, whose outputs are connected to the control inputs of blocks 4 and 5 of keys, a memory block 6 connected to information inputs of the first 4 and 5 second blocks, the outputs of which are connected to the first inputs of the first 7 and second 8 comparison blocks, respectively, the outputs connected respectively through the first 9 and second 10 blocks of matching with the electromagnets 11 and 12 records, block 13 tribute code, the first, second and third outputs of which are connected to the second inputs of blocks 7 and 8 and switch 14, respectively, connected to the composition detection sensor 15 and through the third matching block 16 to the third recording electromagnet 17, at the readout point information processing block 18 connected to blocks 19 and 20 readings.

As the sensor 1 can be used, for example, the sensor PD-3. The sensor 15 can serve as a rail circuit. As blocks 19 and 20, for example, information reading units of the BSU 15UZ type can be used.

The device works as follows.

When the composition approaches the recording point, the sensor 15 generates a signal by which the switch 14 connects the third output of block 13 to the input of block 16. The latter converts the output logic signal of block 13 into a constant current of a given direction. This current, flowing through the winding of the third electromagnet 17, creates a magnetic field that magnetizes all the wheelsets of the train when the vehicle is moved in the area of the third electromagnet 17, and according to the signal given by block 13, the north pole of the third pole acts electromagnet 17, and on the other wheel of this wheelset - southern.

Thus, after passing by the railway

In the third electromagnet 17, all wheels of a vehicle moving along one rail of a track are magnetized by one polarity (for example, the south), while wheels moving on another rail are magnetized by the opposite (north) polarity, i.e. in the zone of action of the third electromagnet 17, the proposed device produces magnetic processing of the wheels of a train,

Upon further movement of the vehicle at the point of recording, its wheels enter the zone of action of the first and second electromagnets 11 and 12 of the record. Moreover, the first electromagnet 11 is located near the rail, along which the wheels of the vehicle, magnetized by the third electromagnet 1, are northward, and the second electromagnet 12, along the rail, along which the wheels of a given train, magnetized south polarity. At the moment of arrival of the first wheelset of the vehicle to the information recording section, a signal appears at the output of sensor 1, which translates counter 2 from the initial state 1.

This state of counter 2 corresponds to the appearance of a signal at the output of the decoder 3. The output signal of the decoder 3 is fed to the first control inputs of blocks 4 and 5, which connect the first and second registers of memory 6 to the first

5 inputs of the first 7 and second 8 blocks respectively, and code signals from the first and second outputs of the block 13, respectively, arrive at the second inputs. The code combination at the first output of block 13 corresponds to the magnetization of the wheel by the south polarity, and the code at the second output of block 13 is magnetized wheels north polarity. Block 7 (8) generates an output signal if

5, the first and second inputs are provided with equal code signals.

Thus, if in the first (second) register of block 6 a code signal is written that corresponds to the magnetization

0 the wheels of a vehicle traveling along a rail, which has an electromagnet 11 (12) located along the southern (northern) polarity, then the output of block 7 (8) shows a signal causing the creation of a dc current (9) in the winding of the electromagnet 11 (12), which creates a magnetic field, the reversing wheel at the time of its passage of the zone of action of the electromagnet 11 (12) from the north (south) polarity to the south (north)

If in the first (second) register of block 6 a signal is recorded that corresponds to the magnetizing wheels of a vehicle moving along a rail with electromagnet 11 (12) along the north (south) polarity, then the signal at the output of block 7 (8) is absent, the winding of the electromagnet 11 (12) is de-energized, and the electromagnet 11 (12) does not act on the wheel at the moment of its passage through the zone of action of this electromagnet, since the polarity of this wheel corresponds to the one given by block 6.

At the time of the arrival of the second, third, etc. the wheelsets of the train composition for the information recording section, the device operates in a similar way. In this case, counter 2 from state 1 goes to state 2, 3, .., n, and decoder 3 outputs signals to the corresponding control of the inputs of blocks 4 and 5, which are connected to the first inputs of blocks 7 and 8 of the outputs of the corresponding registers unit 6. The capacity of counter 2, as well as the capacity of unit 6, corresponds to the number of axes of the rolling stock, which carries out the transmission of information.

At the readout point, the information recorded on the wheels of the vehicle is read out in blocks 19 and 20 and fed to block 18 for processing.

Thus, the device, due to the pre-magnetic treatment of the wheel pairs by the third electromagnet 17, produces the first 11 and second 12 electromagnets to re-magnetise the wheels only in necessary cases, without reversing the currents feeding the windings of these electromagnets.
