Elements and block diagrams have the following.

The sensor 1 for the frequency of rotation of the wheel pair is designed to convert the frequency of rotation into a sequence of pulses, the frequency of which is proportional to the frequency of rotation 1; Structurally, the wheel speed sensor 1 is used in the form of a pulse current generator, the KoMt-gutator 2 is designed to receive pulses from the wheel speed sensor on the PCS counter 3 in the presence of GS signals ul-ravllom for inputs from element 4

NOT and the element OR 6. If there is no signal from element 4, switch 2 is closed and does not pass signals from sensor 1 to the input of counter 3. Switch 2 does not pass signals from sensors 1 if there is a signal from element 6, but in this case passes signal from the generator 12 pulses to that counter 3, in which the switch 2 has a signal from the element NOT 4. Counter 3 is designed to count the pulses coming from the sensor 1 of the rotation frequency of the wheel pair 1 to its input through the switch 2. When the counter is filled, signal l.

The HE 4 element is intended to control the switch 2. If there is no signal from the counter 3, there is a signal at its output that opens the switch 2. If there is a signal at the output of the counter 3, the output signal of the element 4 becomes zero and the signals to the counter 3 stop.

Element 5 is designed to provide an output signal in the presence of voltages at all its inputs, i.e. when all counters are filled in. 3. The OR 6 element outputs the output signal when voltage is applied from counter 3 to any of its inputs. The output signal of the element 6 is used for switching the switches 2 and the key elements 14, 15. The key element 7 is designed to pass the output signal of the element 5 to the input of the one-vibrator 8 when the output signal from the switch 20 appears on its control input. for resetting counters 3 and 9. Pulse generator 12

designed to generate a pulse-d code stored in memory element 23 with a frequency of 1-3 kHz, used to refill counters 3 and fill for the maximum number of additional pulses of counter 9. Key element 13 is designed to transmit pulses from the generator 12 pulses per the switch 20 after the output signal from element 5 arrives at its control input. The switch 20 is designed to emit three signals in the following sequence. Upon receipt at its input of the first signal from the generator 12 pulses at its first output of 50

The device works as follows.

When the locomotive moves without boxing, the switches 2 and the key element 15 are open. Counters 3 and 10 receive frequency signals from sensors 1 of the rotational speed of the wheelsets and the pulse generator 12. Since the capacities of the counters 3 are equal between

is the signal arriving at the control input of the decoder 16. This signal opens the decoder 16, allowing the transfer of information to memory element 22. At the end of the first signal, a signal appears at the second input of switch 20, opening key element 17. After the second signal ends, a signal appears at the third input of switch 20, opening key element 7, Key element 17 is designed to pass signals from a pulse generator 12 the inputs of counters 3 and 9, when there is a signal from element 6 on its control input. Upon receipt of a signal from element 5 on its second control input, key 14 is closed.

Counters 9, 10 are designed to count pulses from a pulse generator 12. The key element 17 is designed to transfer information from the counter 9 to the memory element 18 when the second signal of the switch 20 arrives at its control input. The memory elements 18, 23 are used to store information received from the counter 9 and the decoder 16. The key element 15 is intended To transmit pulses from generator 12 pulses to the input of counter 10, if the control input has a signal from the output of element 6. Decoder 16 compares the information recorded in counter 9 and stored in memory element 18 and zvodit transfer pulse difference to memory element 23 in the presence of a control signal output from the first switch 20.

The meter and the counter 10, in a DC voltage proportional to this code, A DC voltmeter is used as the measuring unit 22.

The device works as follows.

When the locomotive moves without boxing, the switches 2 and the key element 15 are open. Counters 3 and 10 receive frequency signals from sensors 1 of the rotational speed of the wheelsets and the pulse generator 12. Since the capacities of the counters 3 are equal between

In particular, omi are filled at the same time and give signals for switching on elements Ti- and 5, element OR b, element NOT Output elements of element 4 block switches 2, and output signal nigit of element 6 is the key element 15 Pulse incoming to counters 3, , 10 ceases. The pulse generator 12, through the key element 13, begins to pass pulses into a mutator 20, which in turn generates a number of signals. The third signal, number 13, the tator, 20 opens the key element 7 and starts the one-shot 8, which returns to the initial state,

When a wheel of a pair is oxidized, its rotation frequency increases as the pulse frequency sensor from the enemy's frequency sensor increases; as a result, the count of 3 pulses combined with the box and its pair is filled completely earlier S than another counter 3 ;, articulated with a pissing wheelset.

The output signal of element 4 blocks its switch 2 to pass any other pulses into the fully loaded counter 3.

The second impulse of the switch 20 is open: the key element 17 is located, and the information from the counter 9 is transferred to the memory element 18. The third pulse of the switch 20 opens the key 7, and the output signal of element 5 is fed to the input of the one-shot 8. Turning on, the one-shot 8 sets the counters 3 and 9 to the initial state. The output signal of the memory element 23, converted by digital-to-threshold converter 24, starts to enter the diesel locomotive control circuit, reducing the power of the locomotive power unit in proportion to the intensity of boxing;
