The invention relates to the field of accumulation of information, namely, devices for magnetic recording on a ferromagnetic wheel of a moving unit.

The purpose of the invention is to increase the reliability of a magnetic recording device on a ferromagnetic wheel of a mobile unit.

FIG. 1 shows a diagram of an embodiment of a device for magnetic recording on a ferromagnetic wheel of a mobile unit; in fig. 2 and 3 - location of the ferromagnetic mass sensors relative to the rails.

The device contains a shaper 1 of the recording signal, connected by the first input to the output of the sensor 2 of the control of the mobile unit in the recording area, connected by other inputs from the output - ml sensors 3 of the ferromagnetic mass and connected to the first input of the first switch 4, second 5, third 6 and the fourth 7 switches and the first 8 and second 9 elements of the sector record, located along the rails 10, along which the ferromagnetic wheels 11 can move, forming a pair of wheels together with the inc connecting axis 12 of magnetic material . First 8 and second 9 sector recording elements are connected by first inputs to the outputs of the first 4 and second 5 switching units, respectively. The third switch 6 is connected to the second output of the write signal generator 1 by the first input.

The device also contains the first 13 and second 14 inverters, the motion direction determiner 15 and the trigger 16 connected by a counting input to the output of the ferromagnetic mass sensor 3 located between the first 8 and second 9 sector recording elements, each of which is made in the form of windings 17 and located inside magnetic core 18, mated through insulating spacers 19 with sections of rails 10, is limited on both sides by non-magnetic joints 20. The first output of the writing signal former 1 is connected to the first input of the second cable mmutator 5 connected by a second input to the output of the first inverter 13 The output of the second inverter 14 is connected to the second input of the third switch 6 connected to the second input of the first element 8 of the sector recording. The second output of the imaging signal 1 of the recording signal is connected to the first input of the fourth switch 7, which is connected by an output to the second input of the second element 9 of the pie recording. The output of the motion direction determiner 15 is connected to a setup input of the trigger 16, the output of which is connected to the inputs of the first 13 and second 14 inverters and to the second inputs of the first 4 and fourth 7 switches.

The device works as follows.

It detects the sensor 2 of the control of the mobile unit in the recording area, according to the signal of which the imaging device 1 of the recording signal is prepared for outputting information. If the mobile unit moves in the direction from the first element 8 of the pie record to the second element 9 of the pie record, then the trigger 16 is set to a single state by a short pulse from the motion direction determiner 15. The latter provides the connection of the first input signal generator 1 through the first switch 4 to the winding of the first sector recording element 8, and the second output of the recording signal generator 1 through the fourth switch 7 to the winding 17 of the second sector recording element 9. At the entrance of the ferromagnetic wheel 11 of the first wheelset of the mobile unit to the recording area, the first sensor 3 of the ferromagnetic mass is triggered. Its signal causes the signal of the first bit recording and the powering of the first element 17 winding on the first output of the shaper 1. This is the 8 sector write current of the first switch 4, having a direction determined by the information bit on the first output of the imager 1 of the write signal. The current through the winding 17 of the first element 8 of the pie record forms a magnetic flux through its magnetic core 18, sections of rails 10 between non-magnetic joints 20, ferromagnetic wheels 11 and axis 12 of magnetic material. The latter, in the rolling process of a wheel pair along the sections of rails 10 between non-magnetic joints 20, in ferromagnetic wheels 11 form magnetic marks representing the magnetization zones in the form of circular sectors. Upon further movement of the wheelset along the sections of rails 10 between the non-magnetic joints 20, the similar operation of the other sensors 3 of the ferromagnetic mass located along them occurs, which ensures the formation of 11 other similar magnetic labels in the ferromagnetic wheels.

When the sensor 3 of the ferromagnetic mass, which is located between the first B and the second 9 elements of the sector recording, is triggered, the trigger 16 is shifted to the zero state.

which ensures the connection of the first output of the writing signal generator 1 through the second switch 5 to the winding of the second element 9 of the sector record, and the second output of the writing signal generator 1 through the third switch 6 to the winding 17 of the first element 8 of the sector recording. When the wheelset rolls along the rails 10 between the non-magnetic joints 20, mates with the magnetic rod 18 of the second element of the 9-sector recording, the response of the sensors 3 of the ferromagnetic mass located along them leads to the formation of magnetic marks in the ferromagnetic wheels 11 due to the current in the winding 17 of the second element 9 sector recording.

When the wheelset is rolling along the to-rail sections between non-magnetic joints connected to the magnetic core 18 of the second element of the 9 sector recording, the second wheelset of the mobile unit enters the sections of the rail 10 connected to the magnetic core of the first element 8 of the sector recording. When this occurs, the sensors 3 of the ferromagnetic mass located along the sections of rails 10 connected to the magnetic core 18 of the first element 8 of the pie record are sequentially activated, which leads to the appearance of the information bits at the second output of the write signal generator 1 and to the power supply of the windings 17 of the first element 8 sector recording current from the third switch 6. The latter provides the formation of magnetic labels in the ferromagnetic wheels 11 of the second pair of wheels.

After the sensor 3 is triggered, a ferromagnetic mass located between the first 8 and second 9 elements of the sector record, the magnetic marks in the ferromic wheels 11 of the second wheel pair are formed due to the current in the winding 17 of the second element 9 of the sector record. This current is supplied from the fourth xggeater 7 in accordance with the information from the second output of the imaging device 1 of the recording signal. Further, the process of forming magnetic marks in the ferromagnetic wheels 11 of the remaining wheel pairs of the mobile unit proceeds similarly.
