Electro-optical system 5 can also be used for any track machine, carrying out the repair of the railroad tracks.

Opto-electronic system 5 (see figure 2 and figure 3) consists of three functional blocks: photoreception unit 24, one or more fiducial marks 25 and the block 26 of the information processing. Photodetecting unit 24, and unit 26 of the information processing installed on the measuring trolley 2 lining, tamping, leveling machine 1. It is also possible mounting blocks 24 and 26 to any other measurement cart, the light is annoy with the machine 1 and is arranged to move along the track with the car 1.

Reference mark 25 may be secured to the supports 27 of the contact network or other structures along the railway line in the direction of travel of the machine 1 in accordance with geodetic marks the design position of the path. Parts reference marks 25 are modulated led 28, the sensor 29 associated with the led 28 through the circuit 30 controls the led, and an Autonomous power supply 31 for supplying power to the constructive elements of the fiducial mark 25.

Photodetecting unit 24 includes two receiving and analyzing systems 32 and 33, the sensor 34 of the angle of inclination of the railroad tracks and the control module 35, which includes the emitter 36, scheme 37 processing of information signals and a photodetector 38. The output of the photodetecting device 38 through the circuit 37 processing of information signals associated with the input of the emitter 36. The control module 35 is used to activate the led 28, and also produce at the time of passing through the measuring-control truck 2 cars 1 fiducial mark 25 of the control signal, by which the optical receiving and analyzing systems 32 and 33 capture LEDs 28 and converts it into a digital electrical signals. As the sensor 34 of the tilt angle can be used inclinometer. Receiving and analyzing systems 32 and 33 serve to receive the optical image of light is odiada 28 and convert it into digital electrical signals. Each receiving and analyzing system 32 and 33 includes a lens (respectively 39 and 40) and a position-sensitive receiver of optical radiation (respectively 41 and 42)mounted in the plane of the image analysis of the led 28. The optical axis of these systems intersect at the point of maximum distance measurement. Photodetector 38 may be in the form of a photodiode with a lens.

The exchange of information between the fiducial mark 25 and photodetector unit 24 is carried out through four optical channels. The first channel connects the emitter 36 with the photodetector 29 and serves to signal about finding this reference marks 25 in the field of view of the photodetector unit 24. The second channel connects the emitter 36 with a photodetector 38 and serves to activate the process of "capture" of frames. The last two channels connecting the emitter 36 of the optical receiving and analyzing systems 32 and 33, necessary for the formation and capture images of the radiator 36.

Photodetecting unit 24, in addition, exchanges control and measurement information block 26 processing of information through multiple channels. One of the input unit 26 of the information processing associated with the sensor 34 angle (through this channel from the sensor 34 of the angle of the transmitted information about the slope of the photodetector unit 24), W is Roy entrance - with receiving and analyzing systems (this channel is required to transfer converted into electric image signals from the optical receiving and analyzing systems 32 and 33 in block 26 of the information processing to calculate the required values of distance and displacement), and the third input - schema 37 processing of information signals of the control module 35 (through this channel from the control module 35 in the block 26 is passed information about the passage of the photodetector unit 24 fiducial marks 25).

Thus, aggregate data from the optical receiving and analyzing systems 32 and 33 from the control module 35 and the sensor 34 of the tilt angle in the unit 26 of the information processing, where the calculated values of the distance to the led 28 and offset with respect to it, which determines the spatial location of the railroad tracks.

The output unit 26 of the information processing is the output of the opto-electronic system 5 as a whole. The information output unit 26 of the information processing is transferred to the Central processing unit of the video information lining, tamping, leveling machine 1.

Figure 4 presents a schematic diagram of the measurement implemented by the optoelectronic system 5. In the ECO optical receiving and analyzing systems 32 and 33 spaced by a distance equal to the base value B=B1+B2, and the optical axis plumage is ecay the Oz axis of the instrument coordinate system at the point of maximum distance measurement, accordingly, L01and L02while forming angles α1and α2with the Oz axis. The optical axis of the lenses 39 and 40 of the optical receiving and analyzing systems 32 and 33 pass through the pointandon the surfaces of position-sensitive detectors of optical radiation 41 and 42, respectively. Position-sensitive detectors of optical radiation 41 and 42 are located at distancesandfrom the rear nodal points of the lenses 39 and 40. After the capture and analysis of images of the LEDs 28 are given coordinatesandimages in the coordinate system of the position-sensitive detectors of optical radiation. These coordinates are computed value of the distance L1 and the displacement Y1, determining the spatial position of the railway track.

The following shows the principle of operation of the ECO 5.

When the movement track machine 1 from one support 27 of the contact network to another is continuous shooting space optical receiving and analyzing systems 32 and 33, but the resulting footage will not be stored or processed. In addition, the photodetector unit 24 also produces continuous lighting lying before him space using emitter 36. At the time of passing through the pores 27 with the reference mark 25 and the photodetector 29 registers of incident optical radiation from the emitter 36 and converts it into an electrical signal. The output signal of the photodetector 29 is fed to the input circuit 30 controls the led 28, which produces the activation of the radiation source 28. The optical signal from the led 28 falls on the photosensitive area photodetector device 38, which converts incident radiation into an electrical signal. Output from the photodetector unit 38, the signal is fed to the input of the electronic circuit 37 processing of informative signals controlling the operation of the emitter 36. In addition, the electronic circuit 20 processing of informative signals generates a signal on one of the input unit 26 of the information processing. On this signal in the memory of each of the measuring channel are stored frames received by the optical receiving and analyzing systems 32 and 33 and containing images of the radiation source (LEDs 28).

The determination of the displacement of the radiation source (LEDs 28) relative to the base point of the instrument coordinate system in the vertical and longitudinal directions is performed in two stages. First, in block 26 of the information processing calculated vertical coordinates "energy centers of gravity of the image(4) in pixels. The algorithm for determining the energy of the center of gravity is the most simple and allows been recovered from snasti 0,1 0,01...the size of the element position-sensitive receiver 41 (42) of the optical radiation. Then, on the basis of the mathematical model are calculated offset L1 and Y1 relative to the base point, determining the spatial location of the railroad tracks, adjusted for aperpendicular location matrix to the optical axis of the lenses 39 and 40 respectively in the upper and lower channels:

- the value of the distance (alignment) in the coordinate system of the claimed system is equal to

the amount of displacement in the vertical direction (bearing) in the coordinate system of the claimed system is equal to

To reduce bias IPS when there is a deviation of the position of the path from zero measured coordinates L and Y are translated at the end the following formulas:

L=L1 cos φ

Y=Y1-L1 tg φ

where φ is the angle of inclination of the road (coming from the sensor 34 of the angle).

The method of alignment and monitoring of railway track using a lining, tamping, leveling machine and opto-electronic system is as follows.

To ensure the installation path in the design position during its repair requires a three-to fourfold passage lining, tamping, leveling machine 1 in the same section of track. During the first pass, lining, tamping, leveling machine 1 directly behind webpagetitle machine the first can work on smoothing with job design parameters curved track sections (lengths of transition curves with a specific position along the length of the path, elevations in the level and radii of circular curves, these curves). During the first working passageway machine 1 simultaneously with the leveling and tamping of the ballast provide measurements straightened position of the path in space taking into account the position measurement path relative to the working reference marks 25. The measurement results straightened position of the path in space is calculated software job shifts and potemkim the way to the repair area with the aim of using the results of calculation and setup path in the design position or close to the project location subsequent lining, tamping, leveling or the same machine 1 in the second pass. When using optic-electronic systems 5 reading reference marks 25 determine the actual position of the path in the vertical and horizontal planes, and comparing results of the measurement path with project vertical position determines the amount of hoisting the way to ensure that it is in the design position. In this case, to ensure the installation path in the design position or close to it for the second pass will not be required to make the measurement of travel, as software tasks will be formed based on the results of the first pass of the machine 1. Comparing the actual position of vypra the certain path vertically when the first pass of the machine 1 with the calculated lift path and the actual position of the straightened path when the second pass of the machine 1, determine the actual draught of the ways that arose after the passage of the rear undercarriage of the machine. The amount of precipitation received paths define the degree of compaction of the ballast. If between two adjacent working passes of the machine 1 (cars) ran a train load it into account when determining the degree of compaction of the ballast. Similarly calculate software reference for software installation path in the design position with a determination of the degree of compaction of the ballast when the third (fourth) pass lining, tamping, leveling machine 1 (machines).
