In Fig. 1 presents a schematic of the placement of the sensors in the upper and two side rehabilitate; Fig.2 is a structural diagram of one of the blocks of information processing, and Fig.3 design of one of the sensors.

The device comprises (Fig.1) sensor 1 control of oversize, from each of which depart three wires. The first is connected through a filter 2 (Fig.2) low frequency to the peak detector 3, the second wire through the filter 4 low frequencies to the peak detector 5, the outputs of these detectors through an electronic switch 6 is connected to an analog-to-digital converters 7 and 8, the third wire through the filter 9 low frequency connected to the input of Schmitt trigger 10, the first output of the trigger through a differentiating chain 11 is connected to the input of the one-shot 12, the output of which connect the Oia account counter 13 length of oversize to the counting input of which is through the element And 14 is connected through an inverter 15 to the first output of the Schmitt trigger 10 and the output of the generator 16 clock pulses associated with the speedometer 17 composition, the output of generator 16 is also connected to the input of the accounts of the counter 18 start position of oversize. To the inputs of resetting counters 13 and 18 connected to the output of the sensor origin 19, the second output of the Schmitt trigger through diodes 20 and differentiating the chain 21 is also connected to the input of the reset of the counter 13 also outputs the analog-to-digital converters 7 and 8, the one-shot 12, the second output of the Schmitt trigger 10, the output of the counters 13 and 18, the output of the sensor 19 is connected to the interface 22 of the computer 23 connected to the display 24, the control panel 25 acceptance of the supplier, printer 26 and the outer cable communication line 27.

The sensor oversize (Fig.3) contains two hollow metal tubes 28 and 29 outside covered by a polymeric material 30. Pipes are aligned and parallel to the contour of the envelope of the rolling stock. At the end of the pipe 28 is a permanent magnet 31, and at the end of the pipe 29 is fixed reed switch 32. Pipe mounted on bearings for rotation in one plane, parallel to the axis of the path and Parikh sealed tightly in the load-bearing structure. Coaxially with the bearings installed two variable resistance (resistor) 33 and 34, the handle of which is connected with the rotating parts of the bearing through a rubber tube, to the extreme terminals of the variable resistance 33 and 43 of the supplied voltage, a part of which, as of the divider is removed from the average (moving) point. Secondary terminals of the resistor and voltage divider connected to the reed switch consists of three sensor output of oversize connected to respective inputs of the processing unit.

The device operates as follows.

Before joining the rolling stock in the overall area of the gate all sensors 1 occupy the initial position, in which the input of the filter 9 is a high signal, and the inputs of the filters 2 and 4, the zero input. When joining the first carriage structure in the overall area of the gate signal from the sensor trains voltage is applied to the sensor 19 of origin and simultaneously triggered a chain of survey sensors 1 (included the program in the computer 23 through the interface 22.

Since that time, the sensor 19 origin generates a signal of high level at its output whenever the receptacle space (coupler) pass through the plane ohms on the two wires, connected to the inputs of filters low frequencies 2 and 4, are transmitted electrical signals, the amplitude of which depends on the coordinates of oversize (section of oversize) in the plane perpendicular to the axis of the path. These signals are smoothed by filters 2 and 4 and are transmitted to the inputs of the peak detectors 3 and 5. Since the entry of oversize in the plane dimensions of the gate signal from the sensor 1 (the third wire) signal to the filter 9 low frequencies, the output of which appears the switching of the Schmitt trigger 10, namely, the first output connected to differentiating the chain 11, the voltage will change from high level to low (zero), at the other output on the contrary, from low to high. Positive front, the voltage generated on the second output, through differentiating the chain 21, the counter 13 length of oversize is reset, and the output signal of the inverter 15 is allowed to pass clock pulses from the generator 16 clock pulses through the element And 14 at the counting input of the counter 13. In the counter 13 during the movement of oversize through the plane dimensions of the gate is a pulse count.

In turn, the counter 18 by the time of the oversize was counted number of the pulse 18 is reset to zero whenever a sensor is triggered 19 origin, i.e. with the advent of the next car in the plane of the dimensional gate. When the oversize from the counter 18 via the interface 22 in the computer 23 (signal with the second output of the Schmitt trigger 10) will be introduced coordinate of XIRthe horizontal position of the beginning of oversize from the coupler of the car. After the appearance of the oversize counter 18 continues the account further. This allows you to log the possible coordinates (XJHother rehabilitate on the same car.

In order for the distance scale has not changed from the speed change cars, the frequency (interval) pulse is set by signals from the speedometer 17 part installed on the side of the road.

By the end of oversize registered data counter at the input of the filter 9 appears the high-level voltage, which, after smoothing filter will ensure that the switching of the Schmitt trigger 10 in the initial state. When this low-level signal from the second output of the Schmitt trigger 10 is prohibited pulse counter 13. At the same time the positive front, the high voltage from the first output of this trigger through differentiating chain 11 runs one-shot 12. The signal from the detectors 3 and 5 to the inputs of analog-to-digital converters 7 and 8. Thus, only after the registration of the fact of termination of oversize in the computer 23 via the interface 22 is entered from the analog-to-digital converters (ADC) 7, and 8 information about the maximum coordinates of oversize (Y, Yiband YIRand from the counter 13 of the length (lix) on the X-axis (along the car). If the same car has a few rehabilitate attributable to the same sensor 1, all the parameters (XIR, lix, Yib, YIRwill be registered in the computer 23.

Let us consider in more detail the operation of the sensor 1. In the initial condition of the pipes 28 and 29 each of them are located coaxially. When the switch 32 is maximally close to the permanent magnet 31 and the magnetic field contacts will be closed. Through the closed contact of the reed switch 32 on the third wire from the sensor 1 to the input of the filter 9 will be submitted to a constant high voltage level. Accordingly, the Schmitt trigger 10 will be in a single state, in which the first output of the trigger 10 will be a high signal.

The inputs of the filters 2 and 4 opposite from the middle contacts of the resistors 33 and 34 will be energized zero level (when coaxial pipe arrangement is ical contact with the pipes 28 and 29, which deviate by an angle proportional to the maximum values of the coordinates YINand YN. Rotate each pipe around its axis is converted into an electrical signal by means of the resistors 33 and 34. The signal level of each resistor will correspond to the coordinates YINand YN. After the release of oversize beyond the plane of the sensor 1 pipe 28 and 29 by means of rubber bands, which are the ends of the pipe returns to its original position. The reed switch 32 is again closest to the permanent magnet 31 and the magnetic field closes its contacts. The signal at the input of the filter 9 low frequencies is reduced to zero and the trigger 10 generates at its outputs signals indicating the end of oversize.

Sensor design provides the reliability of its functioning. Thus, polymer (or rubber) floor 3, pipe protects them from mechanical damage and at the same time takes good character interaction pipes with oversized cargo. At the same time prevents damage to the cargo. The polymer coating 30 also dampens vibrations of the pipe, which is designed to increase the reliability of their work, and to reduce the measurement error status, and also dampens the amplitude of the pipes 28 and 29 in the process of their interaction with bulky goods or elements of car design. To suppress high-frequency oscillations of the pipe vibration from the passing of the composition, wind or snow effects, etc.,) are also rubber tubes through which the sliders resistors 33 and 34 connected with the bearings of the pipes. Additional smoothing of the oscillations of the electrical signals from the sensor 1 to provide filters 2, 4, and 9.

Thus, the proposed device provides a social effect due to the timely and reliable detection of violations of gauge rolling stock. This registers the degree of oversize, as well as the coordinate origin (XiHand the length of oversize (liXalong the carriage and the maximum deviation (YiB, YiHalong the contour of the envelope of the rolling stock.
