Description

The invention relates to techniques for magnetic recording, namely, to write code on mobile media such as wheels of vehicles.

The purpose of the invention is to increase reliability.

The drawing shows a block diagram of a device.

The device contains sensors 1-6, the element And 7 connected to the sensors 1,2,4 and 5, and the element OR 8, which is connected to the trigger 9 and the element And 10 connected to the sensors 2, 3, 5 and 6, the switch 11 connected to the trigger 9 and pulse converters 12 connected to the electromagnets 13, a memory unit 14 connected to the switch 11 and the switch 15 connected to the trigger 16 and through the converters 17 with the electromagnets 18, end sensors 19-24, the element And 25 connected to the sensors 19, 20 and 22, 23 and the element OR 26, which is connected to the trigger 16 and the element And 27, connect connected to sensors 20, 21 and 23, 24.

Sensors 1-6 and 19-24 are located along the railway track, and the distances between the sensors 1 and 2, 2 and 3, 4 and 5, 5 and 6, 19 and 20, 20 and 21.22 and 23, 23 and 24 are equal the distance between adjacent wheel pairs of the wagon carriage, and the distances between the sensors 2 and 4, 3 and 5, 20 and 22.21 and 23 are equal to the distance between the last wheel pair of the first wagon carriage and the first wheel pair of the second wagon carriage of the wagon, i.e. the distance between the second and third wheel pairs of the car.

The first and second electromagnets 13 are located between sensors 1 and 2, the third and fourth - between sensors 2 and 3, the fifth and sixth - between sensors 4 and 5, the seventh and eighth - between sensors 5 and 6.

The first electromagnet 18 is located between the sensors 19 and 20, the second is between the sensors 20 and 21, the third is between the sensors 22 and 23, the fourth electromagnet 18 is between the sensors 23 and 24. The distances between the first and second, third and fourth, fifth and sixth, seventh and the eighth electromagnets 13 are equal to the third part of the circumference of the wheel, and between the first and third, fifth and seventh electromagnets 13, as well as between the first, second, third and fourth electromagnets 18 are equal to the distance between two adjacent wheel pairs of one wagon carriage. The distance between the eighth electromagnet 13 and the first electromagnet 18 is a multiple of 4/3 of the circumference of the wheel.

This arrangement of sensors and electromagnets allows you to control the position of the car in the recording area and provides recording on each wheel of three magnetic marks, their uniform distribution along the entire circumference of the wheel and simultaneous recording on all wheels of the car first first, then second and then third magnetic marks.

To ensure synchronization when reading information from the vehicle’s wheels, a two-digit code is applied to each wheel in the form of three magnetic marks uniformly distributed along the entire circumference of the wheel.

The device operates as follows.

Before the vehicle arrives at the recording site, the triggers 9, 16 and the switches 11, 15 are in the initial state. In this case, the output signals of block 14 are disconnected from the inputs of the converters 12, 17 and therefore, the electromagnets 13, 18 are de-energized and do not create an electromagnetic field.

When the vehicle passes through the recording section, for example, from the sensor 1 side, at the moment of the first wheel pair of the first car being hit by the sensor 5, the second third and fourth wheel pairs of the car at that moment will hit the sensors 4, 2 and 1, respectively.

The signals from the outputs of these sensors are fed to the inputs of the element And 7. In this case, the output signal of the element 7 is fed through the element OR 8 to the counting input of the trigger 9 and transfers it from the initial state “O to state 1. The output signal” 1 of the trigger 9 is fed to the control input switch 11. According to this signal, the switch 11 connects the registers of block 14 through the converters 12, respectively, to the electromagnets 13. Thus, after the trigger 9 has moved from the initial state О to state Г, the direction of the electromagnetic fields generated by electromagnet 13 is determined by the logical signals recorded respectively in the 14 block registers.

In the registers of block 14 are logical signals that determine the polarity of the magnetic marks of the wheels of the respective wheelsets of the car.

With further movement of the vehicle in the recording area without changing the direction of movement, the first, second, third and fourth wheel pairs of the same car simultaneously run sequentially on the electromagnets 13.

Thus, first the first magnetic marks are applied to all the wheels of the car at the same time, and then, after a distance equal to 1/3 of the wheel circumference, the second, the first and second magnetic marks of each wheel are the first information discharge of this wheel.

When the first wheel pair of the same car hits a sensor 6, the second, third and fourth wheel pairs will then hit sensors 5, 3 and 2, respectively. The signals from the outputs of the sensors 6, 5, 3 and 2 are fed to the inputs of element 10, while the output signal of the element 10 through the element 8 is fed to the input of the trigger 9 and transfers it from state G to the initial state ”0. The output signal ”0 of trigger 9 is supplied to the control input of switch 11 and switch 11 disconnects the registers of block 14 from the corresponding converters 12, the electromagnets 13 are de-energized. Therefore, with the further movement of the car along the recording section in the same direction, the electromagnets 13 do not record magnetic marks on the wheelsets.

When the wheelset of the car is hit by the sensor 23, the second, third and fourth wheelsets of the car will hit the sensors 22, 20 and 19, respectively. The signals from the outputs of these sensors are fed to all inputs of the element 25. The output signal of the element 25 through the element 26 is fed to the counting input of the trigger 16 and translates it from the initial state “0 to state 1”. At the same time, the input of the trigger 16 is received at the control input of the switch 16. The switch 16 connects the registers of the block 14 through the converters 17, respectively, to the electromagnets 18. Thus Thus, the directions of the electromagnetic fields created by the electromagnets 18 are determined by logical signals recorded in the corresponding blocks 14.

With further movement of the vehicle in the recording area without changing the direction of movement at the moment of collision of the first, second, third and fourth wheel pairs with the respective electromagnets 18, these electromagnets 18 record the third magnetic marks simultaneously on all wheel pairs of the car. The distance between the second and third magnetic marks of each wheel is equal to the third part of the circumference of the wheel. When the first wheel pair of the car hits the sensor 24, the second third and fourth wheel pairs of the car will hit the sensors 23,21 and 20, respectively. The signals from the outputs of these sensors are fed to the inputs of the elements 27. The output signal of the element 27 through the element 26 is input trigger 16 and transfers it from state 1 to state 0. At the control input of switch 15, the output signal вход 0 of trigger 16 is received. Switch 15 disconnects the registers of block 14 from the corresponding converters 17, the electromagnets 18 are de-energized. Therefore, with the further movement of the car along the recording section in the same direction, the electromagnets 18 do not record magnetic marks on the wheelsets.

Thus, the electromagnets 13, 18 are turned on only at that moment in time, when in the coverage area of each pair of electromagnets 13 or each electromagnet 18 there is a corresponding wheelset of this car, the first and second marks are recorded on the wheels of the car only when the first wheel pair of the car is between the sensors 6 and 5, the second is between the sensors 5 and 4. the third is between the sensors 3 and 2, and the fourth wheel pair of the car is between the sensors 2 and 1. The third magnetic marks are recorded on the wheelsets of the same car when the wheels are located: the first between the sensors 24 and 23, the second between the sensors 23 and 22, the third between the sensors 21 and 20, the fourth wheel pair of the car between sensors 20 and 19.

If the vehicle reverses its direction of movement at the moment when the fourth, third, second and first wheelsets of the wagons are respectively between sensors 1 and 2 (19 and 20), sensors 2 and 3 (21 and 20), sensors 4 and 5 (22 and 23) and sensors 5 and 6 (23 and 24), then with further movement in a new direction, the first, second, third and fourth wheel pairs of this car will hit sensors 5, 2 and 1, respectively (23,22,20 and 19). The signals of these sensors through element 7 (25), element 8 (26) act on trigger 9 (16) and transfer it from state D to initial state 0. Therefore, switch 11 (15) disables the first, eighth (9-12) block registers 14 corresponding converters 12 (17). The electromagnets 13 (18) are de-energized. During the subsequent movement of the car along the recording section in the same direction, magnetic marks are not recorded on the wheelsets. If then the direction of movement of the car becomes initial, then the recording of magnetic marks on the wheelsets of the car is carried out in the same way as when the car moves in the recording area from the sensor 1 without changing the movement. In this case, the magnetic marks applied to the wheelsets coincide before the first change in the direction of movement and correspond to the magnetic marks recorded 1615014 on the wheelsets after the second change in the direction of movement of the car.

When the vehicle is moving along the recording section from the sensor 24, the code is written to the wheelsets of the car in the same way.
