The drawing shows a block diagram 15 of a device for recording information on the wheels of a vehicle.

The device for recording information on the wheels of the vehicle contains sensors 1 and 2 for detecting wheelsets, 20 connected to the first inputs of the And 3 and 4 circuits, respectively, the second inputs of which are connected to the wheelset detecting sensors 5 and 6, respectively. The outputs of the circuits And 3 and 4 are connected respectively to the first 25 and second inputs of the OR circuit 7 and to the information inputs of the first and second counters 8 and 9, respectively, whose outputs are connected to the inputs of the first decoder 10, the first, second and third high kofibi of which the OR 11 circuit and the delay line 2 are connected to the fault inputs of counters 8 and 9. The first and second outputs of the decoder 10 are connected via OR circuit 13 to the first control input 35 of the counter 14, which is connected by the second control input to the fourth output of the first decoder 10, and the output s - with inputs of the second decoder 15 and information input through the line of the zadser- 40 cable - with the output of the AND 3 circuit. The device also contains a trigger 17 connected to the OR 7 circuit and a switch 18 connected to the key block 19, which is connected to the decoder 15 and memory block 20, 45 electromagnets 21-24, connected respectively through converters 25-28 s

the switch outputs 18. the third circuit And 29, the first and second inputs of which are connected respectively to the inverse output of the trigger 17 and the fifth output of the decoder 15, and the output to the reset input of the counter 14.

The device works as follows.

When the composition approaches the recording area from the sensor 1 sensor, the wheel pairs at the time of arrival of the last (fourth) wheel pair of the first car to the sensor 1 first move the wheel pair of the car to the sensor 5. Signals from sensors 1 and 5 coming to the circuit inputs And 3, cause the output signal to be generated by the AND 3 circuit, which is fed to the information input of the counter 8 and through the OR 7 circuit to the counting input of the trigger 17, transferring them from the initial state to state 1. At the inputs of the encryption 10 pulses 0001, which corresponds to the appearance of a signal at the fourth output of the decoder 10, This signal arrives at the second control input of the reversible counter 14 and puts it into the summation mode. The signal of the direct output set to 1, trigger 17 is fed to the control input of switch 18 connecting the first to fourth outputs of block 19 of keys to inputs of converter 28, 27, 26 and 25, respectively. At the same time, the output signal of circuit 3 through delay line 16 , the delay time of which ri ti is the transit time of the output signal of the AND 3 circuit through the serially connected counter 8, the decoder 10 and the OR 13 circuit, arrives at the information input of the counter 14 and transfers it from the initial state to state 1. This state of the counter 14 corresponds to the first appearance of the signal output of the decoder 15. The block decoder 19 to the signal outputs 15 connects the first through fourth registers block

20 memory through switch 18 and converters 28, 27, 26, and 25, respectively, to electromagnets 24, 23, 22, and 21. Thus, after counter 14 and trigger 17 have switched to state 1, the directions of electromagnetic fields generated by electromagnets 24, 23, 22 and 21, are determined by the logical signals recorded in the first group of registers (respectively in 1, 2, 3 and 4 registers) of block 20, in which there are logical signals that determine the magnetic states of the first , second, third and fourth wheel pairs of the first car.

Upon further movement of the vehicle along the recording section without changing the direction of movement, the first, second, third and fourth wheelsets of the first car pass through the areas of operation of electromagnets 24, 23, 22 and 21, respectively, which record information on the wheels of the car. magnetic state. At the time of arrival of the first wheelset of the first car to the sensor 6, the fourth wheelset of this car runs into sensor 2. Signals from the outputs of sensors 2 and 6 are fed to the inputs of circuit 4, the output of which goes to the information input of counter 9 and through the circuit OR 7 - to the counting input of the trigger 17, while the last of the state 1 goes to the initial state O, and the counter 9 from the initial state goes to the state 1. Since the control input of the switch 18 contains the signal O from the direct output of the trigger 17, the switch 18 turns off the outputs unit 19 from the inputs of converters 28, 27, 26, and 25, electromagnets 24, 23, 22, and 21 are de-energized. Therefore, upon further movement of this car along the recording section in the same direction, electromagnets 24, 23,22 and 21 do not record information on the wheel pairs. Once installed, at the inputs of the decoder 10, the combination of pulses 1001 causes a signal to appear at the first output of the decoder 10, arriving through the OR 11 circuit and the delay line 12, the delay time of which is tg 3: ri, to the reset inputs of the counters 8 and 9 and transfers them to the initial state.

The cycle of recording information on the wheels of the first car of the vehicle ends. When passing the recording section by the following cars of a given composition without changing the direction of movement, information is recorded on the wheelsets in the same way. In this case, the counter 14 on the signals received

from the circuit And 3, successively goes into states 2, 3, 4 and 5, thereby making alternate connection via the decoder 15, block 19 and switch 5 of the second, second, third, fourth and fifth groups of registers of block 20 through converters 28, 27, 26 and 25 to electromagnets 24, 23, 22 and 21.

Thus, when passing through the recording section without changing the direction of movement, the proposed device records information on the wheel pairs of the first car in accordance with logic signals recorded in 1-4 registers of block 20, and on wheel pairs of the second car in accordance with logical signals recorded in the 5-7th registers of block 20, on the wheel pairs of the third car - in accordance with the logic

0 signals recorded in the 9-12th registers of block 20, on the wheel pairs of the fourth car in accordance with the logical signals recorded in the 13-16th registers of block 20, and on the wheel pairs of the fifth car in

5 in accordance with the logical signals recorded in the 17-20th registers of block 20. At the moment the vehicle leaves the recording area, i.e. at the time of the simultaneous arrival of the first wheelset of the second car on sensor 6, and the fourth wheelset of this car on sensor 2, the counter 14 is in state 5, the signal from the fifth output of the decoder 15 is present at the first input of the circuit 29, trigger 17 the output signal of the circuit OR 7 from state 1 is transferred to the initial state O. The signal from the inverse output of the trigger 17 through the circuit 29 is fed to the reset input of the counter 14 and returns it to the initial state.

0When changing the direction of movement

of a vehicle, for example, after a simultaneous arrival of the first wheel pair of the second car to sensor 5, and a fourth wheel pair of this car to date 5, followed by movement of the train in a new direction at the time of the second simultaneous collision of the first wheel pair of the second car to sensor 5, and the fourth on sensor 1, the signal from the output of the AND 3 circuit, is sent to the information input of the counter 8, to the input of the delay line 16, and through the OR circuit 7 to the counting input of the trigger 17, which transitions from state 1 to state O. Thanks to this comm Ator 18 disconnects the inputs of converters 28, 27, 26 and 25 from the outputs of block 19, thereby de-energizing the electromagnets 24, 23, 22 and 21, Counter 8 from state 1 changes to state 2, and a combination of pulses 0010 is installed at inputs of the decoder 10 which corresponds to the occurrence of a signal at the second output of the decoder 10, which is fed through the OR circuit 13 to the first control input of the reversible counter 14. The latter goes into the subtraction mode. The output signal 5 of the delay line 16 arriving by this time on the information input of the IC 14 transfers it from state 2 to state 1. The signal from the second output of the decoder 10, which has passed the circuit 10 OR 11 and the delay line 12, arrives to the fault inputs of counters 8 and 9 and returns them to the initial state.

At the time of arrival of the first wheelset of the first car to the sensor b quarter 15, the wheelset of this car runs into / sensor 2. The signal from the output of circuit I 4 goes to the information input of counter 9 and through circuit 7 to the counting input of the trigger, which is O switches to state 1, whereby the switch 18 connects the inputs of converters 28, 27, 26 and 25, respectively, to the first, second, third and fourth outputs of block 19, since the counter 14 is currently in state 25 1, then the directions of the magnetic fields, creating by electromagnets 24, 23, 22 and 21, are determined by logical signals recorded respectively in the first, second, third and 30 fourth registers of block 20. Thus, when the recording section passes wheel pairs of the first car in a new direction, the proposed device duplicates the recording of information carried out when this car passed the section | of the recording in the original direction. The output signal of circuit 4 received at the information input of counter 9 transfers it from state 0 to state 1.40

Upon further movement of the train in the new direction, the first and fourth wheel pairs of the first car simultaneously hit sensors 5 and 1, respectively. The signal generated at the output of the circuit 45 I 3 goes to the information input of the counter 8, to the input of the delay line 16 and through the IL AND circuit 7 to the trigger input 17, which goes from state 1 to state O, therefore switch 18 disconnects the inputs of converters 28, 27, 26 and 25 from the outputs of block 19, thereby de-energizing electromagnets 24, 23, 22 and 21 Counter 8 from state O goes to state 1 , at the inputs of the decoder 10 55, a combination of pulses 1001 is established, which corresponds to the appearance of the signal at the first output of the decoder 10b entering through the OR circuit 13 to the first control input of the reversible counter 14. The latter goes into subtraction mode. The output signal of the delay line 16, arriving at this time point at the information input of the counter 14, transfers it from state 1 to state O. The signal from the first output of the decoder 10, which has passed the OR 11 circuit and the delay line 12, arrives at the dump the inputs of counters 8 and 9 and returns them to their original state.

When the vehicle’s direction of movement changes to the initial one after the simultaneous arrival of the first and fourth wheel pairs of the car, respectively, to sensors 6 and 2 at the time of the next arrival of the first wheel pair to sensor 6, and the fourth to sensor 2, circuit 4 generates an output signal that goes to the information input counter 9 and through the scheme OR 7 - to the counting input of the trigger 17. Counter 9 switches to state 2, and trigger 17 to the state O. At the inputs of the decoder 10, a combination of pulses 0100 is set, which corresponds to The signal appears at the third output of the decoder 10. The signal from the third output of the decoder 10 through the circuit 11 and the delay line 12 arrives at the reset inputs of counters 8 and 9 and returns them to the initial state. After that, the proposed device works in the same way as when moving the composition through the recording area without changing the direction of movement.
