The device works as follows.

Unit 1 is a permanent electromagnet and carries on

Magnetization of all wheel pairs of 2 floating composition by a field of one half of the ground. Moving wheel pairs 2, magnetized by a field of one direction (polarity), form a magnetic connection with the first input of the track sensor 3, which reacts only to the direction of residual magnetic flux of each wheel pair each generated by block 1. The travel sensor 3 is designed in such a way as to exclude its operation from the passage of unmagnetized objects. The operation of the track sensor of 3 axes, which is caused by the appearance of objects magnetized by a field of a given polarity, is the first step in protecting the device from false alarms, since in this way only a wheel pair of a locomotive or a car, previously passed by magnetization by block 1, can become an object sensor 3, caused by the field of the opposite (other) polarity, will be released after receiving the control command received at the second input from block 7, via the decoder 8,

The information from the track sensor 3 enters the calculator 4 as pulses. In calculator 4, a time-pulse method is used to determine the type of carriages and moving units, a method of counting time intervals using pulse counters and comparing these time intervals with each other. The transmitter 4, depending on the type of the mobile unit, generates signals that are received in blocks 5, 6 and 7.

Block 5 is a set of counters (37-41), which, depending on the category of the mobile unit (four-axle, six-axle, eight-axle or with an odd number of axles), carry out a total count of cars and locomotives — also counting cars and locomotives (see . FIG. 3)

Information about the speed of the first car along the movement of the carriage of the car or locomotive is generated by block 6 on the basis of data received from calculator 4, and transmitted to block 7, which, taking into account the type of this cart, gives a command through the decoder 8 to turn on block 9,

Block 9 is a permanent electromagnet, which carries out the magnetization reversal of one of the wheel pairs 3 second along the movement of the trolley of each rolling stock unit by a Field whose polarity is opposite to the direction of the magnetic field created by block 1,

Such an overrun, one of the axes, allows creating a code from magnetic labels for each rolling stock unit, which is the second step in protecting the device from the false alarms of the axle track sensor. This code has a certain redundancy, and consequently, a certain interference. Such marking of rolling stock units makes it possible to count wagons and locomotives on any part of the railways by installing an axle track sensor that reacts to the direction of residual magnetic flux in a block with a decoder and a counter.

The travel sensor 3 is designed in such a way that it responds to stop

the exact magnetic flux of one given polarity, therefore, to read its axis magnetized by block 9 to receive at the right time (when there is an over-axis axis) it is necessary to switch (reverse), the task of such switching (turn on and off time) is solved by block 7 through a decoder 8. Thus, the device for automatic identification, counting and marking of rolling stock units magnetizes all axes of the identified train with a field of a given direction; for each car or locomotive, after passing over the axle track sensor first along the trolley, the speed of the mobile unit is determined; calculates the turn-on time for reloading the wheelsets; remagnetized by a field of opposite polarity on one wheel pair second in the course of movement of the trolleys of each rolling stock unit; the directional sensor 3 is reversed to receive a signal of the opposite polarity; the code is read on the second carriage in the direction of travel and the axis of the mobile unit is determined; transmits

the command to trigger the counters in block 5.

The calculator 4 (Fig. 2) determines, on the basis of information received from the track sensor 3, the type of carriage and then the axle of the car or locomotive of the rolling stock. This operation is performed by calculating and then comparing the time intervals between the signals coming from the track sensor 3 to the first inputs of the first 10 and second 11 counters.

At the output of the first counter 10, depending on the number of successively received pulses, a parallel binary code is formed, which is converted into a four-invertical code of the converter 12. Therefore, a high potential (control signal) is formed depending on the number of pulses received at the input of the first counter 10 at one of the four outputs of the converter 12 and, obviously, in the open state is one of the electronic keys 14-17,

The signal from the generator 13 through one of the public electronic keys of the calculator enters one of the counters 18-21, which do not produce a parallel binary code indicating the number of received and counted pulses. The number of received and counted pulses is directly proportional to the time interval between the opening and closing of one of the electronic keys, which in turn is determined by the passage over track sensor 3 of two adjacent wheel pairs of rolling stock.

The signal from the first pulse counter enters the second inlets of the second, third, and fourth elements 27-29. Elements 26-29 only provide a signal (control pulse) if the same codes arrive at both their inputs. Elements 26-29 and counters 18-21 can be implemented, for example, based on a software reversible counter.

Information from the second, third, and fourth counters 19, 20, and 21, respectively, goes to the second, third, or quarter element 23, 24, and 25, from the output of which the converted code goes to the first A input at the end.

pogo, third and fourth element. jTOB 27, 28, and 29 comparisons; Second, third, and fourth elements 23, 24, and 25 slow down on the second, third, and fourth elements 27, 28, and 29 of the comparison, preventing them from producing control signals ahead of time in if the car or locomotive is moving with acceleration.

After the operation of one of the comparison elements, the signal from this block is fed to the input of the circuit, which consists of five 32-36 elements, the outputs of which are the outputs of the calculator 4 and are connected to block 5,

The impulse received after the operation of one of the comparison elements via the second logic element 31, resets the first counter 10 to the initial state on the second input, and also triggered the counter from the group of elements 18-21.

The coincidence element generates control signals when pulses arrive at the first and second inputs. These pulses can arrive at the inputs of the coincidence unit and at the same time as the latter differs from the reference element.

The signal from the second counter 11 is supplied through a divider 22, which divides by two, the second input of the first element 20, the first input of which receives information from the first counter 10. The combination of elements 11, 22,20 checks the axes of the car or locomotive parity In the case of passing a mobile unit with an even number of axes, the impulse from the output of the first element will go to the second inputs of the first, second and third elements 32-34. Simultaneously, the first and second elements 30 and 31 are reset to their original state second counter 11 and repeated actuation of the first counter 10 and pulse counter triggered from

elements 18-21, I

Consider the work of the computer 4 (cm, fig, 2) while in the moving train there are moving units with different number of axes. The carriage and locomotive parks are equipped with four-axle, six-axle and eight-axle cars and locomotives

You also know the mobile units of the motorbike fleet (diesel train), in which the first and last cars are five-axle (the first car is three-axle, and the second is two-axle). There are also special loading and unloading machines, in which one carriage is four-axle and the other is three-axle.

Before the start of the computer 4

.dl of elements 23, 24 and 25 it is necessary. to set and establish a constant coefficient. In addition, elements 23, 24 and 25 prevent premature

 actuation of elements 27, 28 to 29 during movement of the identifying mobile unit with acceleration. The calculation of the movement dynamics of mobile units in railway transport shows that the speed of individual cars and locomotives during the passage of a distance equal to the length of the cart of this car or locomotive cannot change by more than 20%. Therefore, when setting a constant divisor factor 23, 24, and 25 to 1.2, the elements 27, 28, and 29 are delayed by a time that is 20% longer than the travel time equal to the length of the identified trolley.

With the passage of the four-axis mobile unit, when the first axis is above the track sensor 3, the first and second counters 10 and 11 are triggered, then a high potential appears at the first output of the converter 12, the first electronic key 14 is opened, and the first counter 18 starts counting. After the passage of the second axis, the counters 10 and 11 are re-triggered, and the high potential from the first output of the converter 12 is moved to its second output, therefore, the first electronic key 14 is closed, and the second opens. The first counter 18 stops working, transmits information about the number of counted pulses in the parallel code to the second inputs of the second, third and fourth elements 27, 28 and 29, Second counter 19 at this time begins its work and information on. the second divider 23, the output of which is connected to the second element 27, the second element 27 will work when the number of pulses goes to counter 19 by 20% more uneven

whether on the counter 18. It is possible, because The base length of the four-axle mobile unit is significantly longer than the length between the axles of the two-axle bogie.

The operation of the element 27 indicates that the first in the course of movement of the mobile unit of the carriage is two-axis. The information (pulse) from the output of element 27 goes to the first inputs of the first and fourth elements 32, 35, and also through the first input of the second element 31, the first counter 10 and the first and second counters 18 and 19 are reset.

The arrival of the third axis triggers the first and second counters 10 and 11, and the potential of the first output of the converter 12 is high again, since the first counter 10 was at that moment in the initial state. The second carriage is biaxial, so the cycle of operation of the described blocks is repeated, however, after the fourth axis, the first element 26 will work, since the codes at both its inputs are identical at this moment. After the first element 26 is triggered, the first input of the first element 31, as well as the fourth input of the second element 32, causes resetting of all the counters. The signal from the output of element 26 also goes to the second inputs of the first, second and third elements 32, 33 and 34, but only the first element 32 is triggered, since the signals to it are received from both inputs, which fixes the passage of the four-axis mobile unit.

The passage of the six-axle mobile unit will trigger the third element 28 and the second element 33, and the presence in the train of an eight-axis mobile unit will activate all the counters 18-21, the fourth element 29 and the third element 34 will work.

Consider the work of the computer 4 in the identification of a mobile unit, in which the first carriage is three-axis, and the second is two-axis.

The first axis, by triggering the first and second counters 10 and 11, sets the first output of the converter 12 to the high potential position, through which

open the first electronic key 14 the beginning of the counting of pulses by the counter 18,

The arrival of the second axis causes the high potential to switch from the first output of the converter 12 to its second input, the second electronic key 15 of the calculator 4 opens and the second pulse counter 19 starts. The closing of the first electronic key 14 of the calculator interrupts the counting of pulses by the first counter 18, and a code proportional to the number of received pulses arrives at the second inputs of the second, third and fourth elements 27, 28 and 29.

The arrival of the third axis interrupts the counting of the second counters 19, however, the second element 27 in this Case does not work, because for the second counter 19, it is necessary to accept 20% more pulses than the first counter, and there are no conditions for this (the third axis arrived and the high potential from the second input of the transducers of code 12 switched to its third input), the fourth axis the considered mobile unit is located at a distance significantly greater than the distance between adjacent axes of one bogie, so after 20% of the time, the third element 28 will work, then the first counter 10 and counters 18, 19, 20 will reset to also on entry s second, fourth and fifth elements 33, 34 and 36 m Postup pulses from the third element 28. In the fourth pass, and then n axes of the work element 27 and the second biaxial zaregistriruets trolley. The signal from the output of the second element 27 will go to the inputs of the first and fourth elements 32, 35, but only the fourth element 35 will work, since the control signals have been received from both the first and second inputs. Next, the reset of the first counter 10 and the first, second counters 18 and 19 through the second element 32 by a signal from the element 27 will be reset, and the second counter 11 is reset by a pulse from the output of the fourth or fifth elements 35 and 36 through the first element 30.

The signals from the first outputs of the calculator 4 are received respectively at the first inputs of the block (see Fig. 3), which consists of counters. Counters

Information from the second outputs of the calculator 4 is fed respectively to the second inputs of the block 6. The speed is determined by dividing the distance traveled by the travel time of this distance. This operation is carried out by element 50 (see Fig. 4) in real time.

The proposed device assumes the reversal of one of the axes of each mobile unit by a field of opposite polarity. Such an axis is the second axis in the second along the carriage of the mobile unit.
