SU1244171A1 - Device for recording information on moving ferromagnetic wheel - Google Patents

Abstract

The invention relates to a magnetic recording technique and can be used for the operational control of railway transport operations. The purpose of the invention is to improve the recording quality due to the formation of a contrast magnetic tag. When the ferromagnetic wheel (FC) 1 enters the recording area, the monitoring sensor 8 activates the shaper 7. When the FC 1 between the rail and the recording bus 4 changes the magnetic resistance to the magnetic flux, the magnitude of the sensors 2 of the ferromagnetic mass is monitored and information about their value at the inputs of subtractive amplifiers (VU) 6. During the movement of FC 1 - a position is created such that the center of the FC 1 is aligned with the axis of the head of the CS ®

Description

the recording (GZ) 3 and at the output of the control unit 6 a Wits-6 signal, which will issue a command to connect the GZ 3 to the driver 7. Powering a GZ 3 with current. The invention relates to a magnetic recording technique and can be used for the operational control of the railway transport operation.

The aim of the invention is to increase the recording quality by forming a contrast magnetic tag.

FIG. 1 is a block diagram of the device in FIG. 2, view A in FIG. 1.

The device contains a ferromagnetic movable wheel 1, sensors for the presence of ferromagnetic mass 2, recording heads 3, recording bus 4, switching units 5, subtractive amplifiers 6, recording signal conditioner 7, control sensor in recording area 8,

rail 9.

The device works as follows

At the entrance of the ferromagnetic wheel 1 in the recording area sensor control 8 includes a driver 7,. When the ferromagnetic wheel 1 is in the space between the rail 9 and the recording bus 4, the magnetic resistance to the magnetic flux changes, this value is monitored by the sensors of the ferromagnetic mass 2 and the information about their value is output to all inputs by a subtracting amplifier 6 "With two wheels 1, this creates the position that the center of the wheel 1 is aligned with the axis of the recording head 3; in this case, at the first output of the subtracting amplifier 6, the signal that will issue the command to connect this bifurcated amplitude and polarity is blighted approx. 5 commutation, with the result that a corresponding label is created. 1 il „

The switchboard is connected to the recording signal shaper 7. A switching unit 5 powers up the recording head 3 toks of a certain amplitude and polarity, as a result of which a corresponding mark is created. With a slight delay in time, a signal appears at the second output of the detracting amplifier 5 informs shaper. 7 about the need to change the information to be recorded „
