Truck 10 equipped with a vertically installed line 11 and the navigation receiver 12. On the trolley 9 is installed dot optical laser device 13. And bogie frames 9 and 10 are equipped with docking ports 14 for connector and connections, each of which is made in the form of cups 15 and 16-pin separately installed n the different frames.

The 2 meter width of the railway track consists of two optical laser devices 17, mounted under the frame of the first truck 9 above their heads rails 18.

The device 3 for removal of the profile rail track consists of a vertically mounted on the second carriage 10 line 11 and mounted on the first carriage 9 point optical laser device 13, and line 11 is equipped with a set of photodetectors 19 arranged on the divisions of its scale.

Each optical laser device 17 gauge 2 width of the railway track is made of a matrix, for example, from a laser diode modules of the Institute of General physics, RAS, and is connected through the corresponding block 7 of the signal processing by the microprocessor 5.

The photodetector 19, mounted in the scale line 11, is connected via a matching unit 7, the processing of the signals to the microprocessor 5.

Device coordinates 6 includes Navigator 20 and the database 21 digital electronic maps of sections of railway track. The first port of the microprocessor 5 is connected to the server port 22 connected through the communication channel via the antenna 23 with antennas 24 transceivers 25 in the form of smartphones, and the second port of the microprocessor 5 is connected to the navigation device 20 coordinates 6.

In the electronic memory is a database 21 with digital maps railway stations belonging to a service area of the service path. The microprocessor 5 is connected to the server port 22 connected through the communication channel with the transceivers 25, included in the portable terminal managers travel teams.

In the electronic memory of each portable terminal is placed text and photographic files of technical specifications for the corresponding track repair crews and the local database with a digital electronic map railway stations work. On the map the elements of the path to be repaired this track repair crew, associated with their rail picket and navigation coordinates. In the electronic memory of each portable terminal installed software application support file sharing between the wearable terminal and the computer operator of the control point.

Functions of the software user interface of the operating system associated with a software application built-in electronic modules fotovideostore and satellite Navigator 20.

Mobile complex for diagnostics of railway track works as follows.

When moving by rail self-propelled Tran is tailor the means of the two linked trolleys 9 and 10 is the dimension of the gauge, the way of measuring a width of 2 and the slope of the path in the vertical plane of the device 3 for removal profile. Installed on the cart 9 device determining the geographic coordinates 6 determine its location.

Two laser devices 17 mounted above the rail heads, determine the distance to their inner edges by fixing the receivers on a matrix measuring the boundaries of the distances to the rail head 18 from their soles. The distance between receivers on the matrix strictly fixed relative to the mounts on the carriage 9. The signals from the receivers, laser devices 17 are processed in blocks 7 and fed to the microprocessor 5, which computes the size of the measured width of the railway track in a particular place under the truck 9. Beams of each laser device 17 is directed perpendicular to the surface of the rail head 18 and parallel to each other (Fig).

Automatically determines the position of the emitters to receivers on the matrices laser devices 17, coincident with the inner edges of the rails 18. They are known regarding the design of the trolley 9 distances calculated true width of the rail track. Data on the constructive dimensions of the truck 9 and spatial layout of laser devices 17 incorporated in the database 21.

On straight sections of railway track mobile system produces a continuous recording of the signals from the receivers, laser devices 17. This is Ignacy processed and entered in the form of an image of the cross section of railway track in the microprocessor 5. At the same time data on the location of the carriages 9 and 10 is continuously output from the Navigator 20.

In places where the measured track width of the track exceeds the limit 1520+6-2mm, request data path width of this place from the satellite. The microprocessor 5 is a comparison of the two images. If these differences are confirmed, the microprocessor 5 generates a warning signal (Fig).

This signal is applied to the transmitter with the antenna 23 and a communication channel to a portable terminal railway worker. Railway engineers take measures to eliminate differences in the width of the railway track.

The carriage 9 has not sprung suspension and therefore the speed can be quite large. The roughness of the path can be recorded using laser levels of the Black, Nedo, Stabila, Robotoolz and others.

Signals are recorded continuously and transmitted to the wearable terminal railway workers, which eliminates the deficiencies.

On the curves of the track sections, the measurement of the width of the path is specified as the measurement is made by laser devices 17 under the truck 9 between its wheels. Matrix length of the laser device 17 must overlap the stems and approaches the rail curve track sections under the cart 9 to all the time be trace the inner edge of the soo is relevant rail head 18. The movement of the trolley 9 is possible by performing axles with wheels swivel in a horizontal plane, for example, on the pins, as it is performed in a two-axle bogie wagons.

On the truck 9 low base its wheels are fixed on the brackets of the frame without hinges, pins and rowlocks.

The measurement of the slope on the fixed sections of railway track produced by spot laser device 13 mounted on the carriage 9 and line 11, a vertically mounted on the cart 10. Vertical installation line 11 is provided by moving its centre of gravity of the bogie frame for enhanced stability. The operator remotely controls the movement of the carriages 9 and 10. The cart 10 in this case down from the truck 9 and moves necessary to measure the slope distance.

Using the navigation receiver 12 mounted on the cart 10 and connected through the communication channel with the device coordinates 6, determine the distance of the location of the cart 10 from the truck 9.

When this Cup 15 on the trolley 9 release pins 16 mounted on the cart 10, and thus the current path connecting the nodes 14. 7 and 8 shows a variant of the coupling with an inflatable pins 16, which increase in volume when the remote operation of the pump and recorded in the cups 15.

Figure 9-11 pin is particularly the articulated quadrilateral, which can extended and retracted in the slots of the Cup 15 horizontal drive traction (drive not shown).

The angle of the track α is determined by the formula:

tgα=Δh/D

where Δh is the excess or the lowering line 11 in the divisions of the scale,

D is the distance (range) to the line 11 from the truck 9.

For example, we take ∆ H=20 cm, D=100 mm, Then α=arctan 20/10000=0,11°.

When ∆ H=10 cm, D=10 m, Then α=arctan 10/1000=0,57°.

The signal from the emitter of the laser device is made by one of the photodetectors embedded in dividing line 11. Next, the signal is converted to one of the signal processing units in the tilt angle. Device for the removal of the profile rail track works as a laser rangefinder with reference vertical movement line 11.

Data on the slope of the path is transmitted to the microprocessor 5 for further processing and transmission to handheld terminals railway worker.

Based on the results of diagnostics of railway track using terrestrial mobile diagnostic tools and space remote sensing tools are registered and identified defects and their location with reference to a digital electronic map of Railways rail picket and the absolute coordinate system GLONASS/GPS/GALILEO. On the computer operator's dispatch center slugbot prepared technical specifications for track repair crews to carry out the necessary repair work. Technical specifications for repair crews form as sets of text and photo files that are recorded in the portable terminals each Manager of track maintenance teams. In the process of technical tasks coordinate and photographic data from the technical specifications are used to control the correctness of the identification of items subject to repair. For this purpose, the head of the corresponding track repair crews or his deputies take pictures of the repaired items agreed with the terms of reference angles and the scale and send pictures along with information about the real coordinates and the global current run-time images.

The use of cell phone or Internet connection to send files and messages is determined by the amount of information or the availability of communication channels. For example, to send fotovideoporno the Internet is the preferred, and for telephone conversations preferred cellular telephone service because of less restrictions compared to the network Wi-Fi zones having a stable connection.

FIELD: railway transport; permanent way.

SUBSTANCE: invention relates to methods of checking and forecasting condition of rail track. According to proposed method, running course of body of track-testing car is measured by means of inertia navigational system installed under pivot of test bogie, and running hunting angle of test bogie relative to body is measured by means of angular displacement transducer. Then, using axle box-rail transducers, distance from flanges of corresponding wheels of bogie to rail heads are measured. Basing on obtained information , running courses of rail lines are calculated as running course of body minus running hunting angle of test bogie relative to body minus running angle of parallel misalignment of flanges of wheelsets of test bogie and heads of rail lines. Then running values of horizontal irregularities of rail lines are found as product of bogie base by deflection of running course of rail lines from running averaged courses of rail lines on bogie base calculated from courses of rail lines. Running radii of curvature of rail lines are found by dividing bogie base by measured increment of course angles of rail lines on bogie base.

EFFECT: provision of chordless (single point) method of checking leveling of rail lines.
