Temperature sensors are installed near the internal and external sensors, and the magnetic pedal is installed below the rail of the track under the flange of the wheelset.

The diagram shows an automatic device for controlling the shift of the axle box axle wheels of wagons and the wear of the rolling surfaces of the wheels of the wheelset.

The device comprises a unit 1 for reading data on the state of the rolling surfaces of the wheels of a wagon’s wheelset, connected to unit 1, a unit 2 for processing the obtained data and outputting results, and also a unit 3 for displaying the obtained results connected with the unit 2.

Block 1 contains external sensors 4, internal sensors 5, a magnetic pedal 6 and temperature sensors 7, while external sensors 4 are installed on the outside of the rail 8 of the rail track, internal sensors 5 are installed on the inside of the rail of the rail track, the magnetic pedal 6 is mounted on the rail 9 of the rail track under the flange 10 of the rim of the wheel 11, resting on its rolling surface 12 on the working surface 13 of the rail 8. Temperature sensors 7 are installed near the sensors 4 and 5 or, more specifically, in the heat zones 14 of the sensors 4 and 5. Under heat second zone 14 of the sensor 4 or 5 herein is meant the minimum temperature area value to the maximum of its values, beyond which the sensor 4 or 5 starts with errors.

Block 2 contains a synchronizer 15, to which sensors 4, 5 and 7 are connected. By means of a synchronizer 15, block 2 is connected to block 1 and elements of this block. Block 2 also contains a microprocessor device 16 and a microprocessor device 17, which are connected to the unit 2 a hub 18 for transmitting data over a local area network, while the microprocessor devices 16 and 17 are connected to external sensors 4 and internal sensors 5.

Block 2 also contains a central server 19 connected by an RS232 cable 20 to a synchronizer 15. Server 19 is connected by a communication line to a hub 18, which is connected by a communication line 21 to a microprocessor device 16.

The device comprises a unit 3 for displaying results with a computer 22 and a workstation (AWS), while the unit 3 for displaying the communication line 23 is connected to the central server 19. Unit 3 also contains means 24 for signaling the approach of the train connected to the synchronizer 15.

The device contains a unit 25 for reading data about the state of the axleboxes of the wheelset 26, which is connected to the block 2 for processing the received data. Block 25 contains emitters 27 located on opposite sides of the wheel pair 26, mounted opposite the axle box 28 of the car wheel pair, triangulated laser action sensors 29 in three-dimensional space located in front of the wheel rims 11. The emitters are connected to the synchronizer 15. The triangulation sensors 29 are connected to the corresponding (on-board) microprocessor devices 16 and 17. Thus, the microprocessor devices 16 and 17 and the synchronizer 15 are also included in the block 25.

The device operates as follows. When rolling along the rails of the rail track of the car, each wheel pair 26 of the car with wheel 8 runs over the magnetic pedal 6 with the rim and this pedal turns on the unit 1 for reading data on the state of the rolling surfaces of the wheels of the car wheel pair, as well as the unit 25 of the device.

As a result, the external sensors 4, internal sensors 5 in a given period of time read data on the state of the rolling surface 12 of the wheel of a certain segment of the wheel surface in the visibility range of the left and right according to the scheme of the pair of sensors 4 and 5. With further rolling of each wheel of the wheel pair along rails 8 of the rail the following pairs of sensors 4 and 5 are included in the operation along the wagon, while according to the indicated scheme of the device, the following pairs of sensors read data from the wheel about the state of the rolling surface of the wheel surface segment wheels. The described cycles for reading data on the state of the rolling surface of each wheel of a wheelset are repeated around the entire perimeter of each wheel of the wheelset.

Sensors 4 and 5 pick up the reflected signals and send them to the synchronizer 15, where they are synchronized on the sides, the number of the wheelset (in a row) and the signal level. Next, the signals from the synchronizer are sent to the server 19, where they are processed, compared with the specified comparison parameters and, in case of discrepancy with the specified comparison parameters, are automatically transmitted to the workstation and computer 22 in the form of alarm information.

At the same time, when the device is in operation, the wheel pair, when it is rolling along the rail track, passes through the block 25 of the axle box data reading device 26 of the wheel pair 26, and the block 25 is turned on when the wheel of the wheel pair is pressed onto the magnetic pedal 6 in the same way as described above. When this occurs, the signal from the magnetic pedal to the emitters 27, which emit signals and feed these signals to each wheel rim of the wheelset, fix the position of the wheels relative to the axle boxes in a given period of time, while the triangulation sensors 29 read the position of the axles relative to the position of each rim of the wheel couples. When the axle boxes pass by the emitters 27 and sensors 29, the latter read out the state of the axlebox axle boxes, they pick up the emitters signals reflected from the axle boxes or the shift of each axle box relative to the axis of the wheelset, send signals to the synchronizer 15, where the signals are synchronized on the sides of the wheelset, number wheelset (in a row) and signal level. Next, the signals from the synchronizer are sent to the server 19, where they are processed, converted into state parameters of axleboxes and necks of the axle of the wheelset, and these parameters are compared with the specified control parameters of comparison. The processing of the obtained parameters is carried out according to the difference between the positions of the wheel and the axle box at the time of measurements, while the specified difference corresponds to the linear displacement of the axle box on the neck of the axle of the wheelset. According to this offset, the axle box is judged on the axle shafts of the axles of each wheelset passing through block 25. If the axlebox displacement parameters do not match the wheelset axis with the specified offset bias parameters, an alarm is generated that is automatically transmitted to the results display unit 3 and to the workstation in the form of alarming information.
