A device for determining the serviceability of railway track in which the analyzed track with track machine continuously send a signal to the laser emitter, the reflected signal takes the photodetector, and after converting the signal values of the parameters of the track compared to a priori known value.

This method for determining the serviceability of railway track is implemented by a device, which is installed on a track car with a support rail trucks and includes a hinge mounted on the measuring bogies on either side of the load devices laser diodes and a photodetector mounted on the movable part of the load devices. (Ed. St. USSR N 1796514, B 61 K 9/08, 1993).

The disadvantage of this method and a device implements is increased wear of the measuring equipment and the low speed limit of the machine (about 40 km/h), as this method of condition monitoring of railway track refers to the contact methods of measurement, thus Seralago path, implementing the control method, which make prelaunch calibration of sensors for measuring parameters of the radius vectors from the tricks of sensors to points lying on the upper and inner side surfaces of the rail heads, and memorize the calibration data, during the movement of the car-potenzmittel cyclically measure in real time the current values of the traversed path, the current values of the power factors of the dynamic interaction between rolling stock and rail track, the current values of the height of the irregularities on the running surface of the rails, the current values of the radii-vectors, the current values of the orientation angles of the car-potenzmittel in a geographic coordinate system and accelerations in the direction of the axes of the associated coordinate system car potenzmittel obtained current values memorize, calculate the geometrical parameters of rail track, analyze and evaluate its condition and remember the results.

This method of condition monitoring of railway track is implemented by a device containing two sensor vertical accelerations books installed on buildings books one of the wheel pairs in nikolovo part of the car-potosmart is the operating heads of the rails relative to the body, mounted on the outer surface of the bottom of the car-potenzmittel, two proximity sensor is an optical wavelength range of the measuring gauge mounted on the unsprung frame, a wheeled truck in nikolovo part of the car-potenzmittel, two sensor vertical displacements of the books relative to the body mounted on the car body-potenzmittel over-values of the pair of wheels in nikolovo parts, sensor of the traversed path, mounted on the housing of one of the books of the measuring wheelset, and mounted on the side of the car-potenzmittel control computer system, including personal electronic computer (PC). (RF patent N 2074829, B 61 K 9/08, E 01 B 35/00, 1997).

Method of condition monitoring of railway track and a device for its realization by the patent RF N 2074829 on community tasks and functional - structural implementation is closest to the proposed invention and is selected as a prototype.

The disadvantage of this method of condition monitoring of railway track and a device implements is the lack of accuracy and reliability control, so as to measure only the deviations of geometrical parameters of the track from Shane-potenzmittel, as well as the presence of methodical errors due to low rigidity of the car potenzmittel when the control parameters of the track with the location of the sensors on a long basis.

In addition, the disadvantage of this method of condition monitoring of railway track and a device which implements a synchronous reading of data from sensors on the principle of his actions are asynchronous, resulting in periodic foray phase error.

Convert a sequence of data blocks in the block sequence coordinates of the position of the car-potenzmittel in inertial space by aligning the beginning of the associated coordinate system with focus strapdown inertial navigation system, transform the sequence of data blocks in the block sequence coordinates in the associated coordinate system of rail track, determining the position of the upper and inner side surfaces of the rail head in space is ekovich surfaces of the rails used for the above calculation of geometrical parameters of rail track, while measuring the current values of the traversed path, the current values of the power factors of the dynamic interaction between rolling stock and rail track, the current values of the height of the irregularities on the running surface of rails, parameters radius-vectors of the orientation angles of the car-potenzmittel in a geographic coordinate system and accelerations in the direction of the axes of the associated coordinate system car potenzmitel.

The essence of the proposed method of monitoring the status of the track - defining position in inertial space sequence Directive, extended in the direction of movement of the VPI curves belonging controlled surfaces of the rail heads, the calculation of geometrical parameters of rail track measuring power factors of the dynamic interaction between rolling stock and track, measure the height of the irregularities on the surface * measurement results in an unreal time.

To understand the proposed method, we consider the interaction of the strapdown inertial navigation system (beans), two sensors measuring the distance from some fixed points of the body to the upper and inner side surfaces of each of the rails (RK 1, RK 2), two accelerometers to measure the current values of the vertical accelerations of each of the buildings books wheelset (VUB 1, VUB 2) and a control system with a set of software.

These bins and the sensors are located near the wheel pairs of the truck nikolovo of the VPI, as shown in Fig.1 and 2, and have accuracy characteristics and performance sufficient to perform the task.

Of all possible coordinate systems selected combination of the three coordinate systems: geographic (latitude, longitude and height above sea level), the associated coordinate system of the VPI, the beginning of which is placed in the focus point bins, and associated coordinate system of rail track, the origin of which lies in the middle of the line segment tangent to the surfaces of riding left and right horizontal rails ideal way is in the vertical plane, Gosta. This combination of coordinate systems is optimal.

Before driving VPI identify and remember the geographical coordinates and altitude of the launch, clarify and remember the original calibration values of the constant C1, C2 (Fig.2) and the variables R1. ..R4 radii-vectors connecting the tricks of the devices controlled by the surfaces of the rails.

Interaction beans and sensors for example control the geometry of the surface of the left rail (Fig.4 and 5).

The geometric sum of the vectors V1 + V2 + V3 + V4 = 0. If the calibration VPI stands on a horizontal section of the path, the vector V4 horizontal and its projection on the vertical equal to 0.

During the movement of the VPI beginning "On" related coordinate system, the track moves along path 4 path to point "O'" (Fig.5). If, for example, in this place there is a drawdown of the left rail, then it is numerically equal to d - projection of the vector V4 on vertical space.

The method involves asynchronous reading of data from the bins and sensors with the extrapolation of current values at the time of issuance and individual binding extrapolated data to the current values of the distance and time. Opti provides high measurement accuracy and the ability to install sensors, phase and time characteristics are not identical. Subsequent binding of asynchronous data to prescriptive segments traversed path allows the calculation of the parameters of the track and analyze their status in near real-time on standard and special techniques. Correction of measurement results according to the SNA and the radar is in unreal time.

Device for condition monitoring of railway track works as follows.

From the remote control 16 operator is introduced into the bins 7 via the controller 11 geographical coordinates and altitude of the launch. Geographical coordinates of the starting point or calculated SNA 8, or taken as the height above sea level of a priori data. Receiving, memorizing and processing the data binding to the terrain, beans 7 enters the measurement mode.

Before driving VPI produce prelaunch calibration of the complex on the section of rail track, geometrical parameters of which are known. The calibration settings are remembered.

In the process of motion sensors 1 VUB form of real-time signals, the current values are proportional to the projection of existing skorniakov 1 VUB have the bandwidth to 20 kHz, they arrive at the corresponding input of the controller 10, where it is converted into digital form and attached at the time of admission to the current value of the traversed path.

The path is measured in real time using a sensor 5 DPP installed on the housing of one of the books of the measuring wheelset, which is kinematically connected to its input shaft. The sensor 5 DPP generates a sequence of pulses, the frequency of which is proportional to the velocity of the VPI, and the potential signal direction. The signals from the sensor 5 DPP is coming to the PC 6, which are scaled by reducing the pulse repetition rate to optimize measuring and computing process based on the criteria of "accuracy - reliability". Next, the scaled pulse sensor 5 DPP arrive at the corresponding inputs of the controllers 10 and 11, which simultaneously counts the number of received pulses and form a code of distance traveled with respect to the direction of movement.

The sensors measure distances 2 RK 3 SHK and 4 Bq to corresponding surfaces of the rail heads cyclically, asynchronously with respect to each other, beans and DPP, generate real-time information parcels with current mn is Chi. The repetition rate of the parcels can reach up to 1.25 kHz. Information packages from sensors measuring distances 2 RK 3 SHK and 4 Bq arrives at the corresponding inputs of the controller 10, where each of the parcels individually bound to the current value of the traversed path and remembered.

Binns 7 contains three angle sensor, made in the form of laser gyroscopes, and three sensor linear acceleration. The axis of sensitivity of the sensors are located along the respective axes of the associated coordinate system, whose origin is the focus of beans. The microcontroller that is part of the Binns, converts the analog sensor signals into digital form, and calculates the derived parameters.

Information from the bins 7 are issued in real time to the controller 11 cycles with frequencies up to 250 Hz in the form of current values calculated (extrapolated) at the time of issuance of the navigation parameters of movement of the VPI in the associated coordinate system (x, y, z): angles of azimuth, roll and pitch, longitudinal, lateral, and normal acceleration along the respective axes, latitude, longitude and altitude, and speed. The controller 11 receives data from the bins 7, and each received current value is bound at the time postmodem time value. The current values of time are formed BTV 13, they go to the controller 11 and PC 6. Tied values are remembered.

The current values of geographical coordinates (latitude and longitude location) come from the SNA 8 to the controller 11, which are attached at the time of admission to the current values of the distance and time.

Radar (RL) 9 during the movement of the VPI interacts with the location on the test object along the track passive transponders (ON). When passing another ON RL 9 generates a signal identification, which is transmitted to the controller 11, which is bound at the time of admission to the current value of the traversed path.

In the process of receiving data controllers 10 and 11 form the information data packets bound to the current value of the distance and time, which in near real-time and randomly come in over the network in two addresses: PC 6, for storage in BDRC 14 as a source of information, and in CAT 12 for further processing. Within the same packet data optimized (deleted duplicate and unlikely values) and placed in order of receipt. PC 6 prevents the overflow of the buffers KIT, excluding therefore the loss of data, cost of temporary loss of precision bind to the current value of the traversed path. With the release of the buffers specified accuracy of binding is restored. Thus implements a mechanism to change the interval of the quantization of distance traveled by the criterion of "accuracy-reliability".

CAT 12 in near real-time receives and processes the methods of inter - and extrapolation of packets of source data, leading them to a sequence of data blocks that are bound to sequence policy sector (for example, 0.25 m), traversed by the axis of the measuring wheelset with placement in relation to the sensors measure distances 2 RK 3 SHK and 4 Bq, beans 7 and VUB 1 on the back of the VPI.

Then the CAT 12 in near real-time converts the original Directive sequence of data blocks in the block sequence coordinates of the position of the VPI in inertial space as a sequence of blocks of the coordinate position of the focus Binns 7 - the beginning of the associated coordinate system (x, y, z) VPI.

Next CAT 12 in near real-time converts the original Directive sequence of data blocks and the block sequence coordinate petranto the beginning of the associated coordinate system (s, h, l) track and coordinate of the upper and inner side surfaces of the rail heads in the associated coordinate system of rails.

On the computed policy-coordinate position of the VPI and the track in the space CAT 12 calculates in near real-time complex geometrical parameters of the track, makes the analysis and assessment of its condition and results transmits over the network to the personal computer 6 for storage in BDRC 14 and printing in the rate of movement of the VPI on the printer 15.

The scaling results of the control labels radar 9 and refining the geographic coordinates of the path according to the SNA 8 is produced on the PC 6 in an unreal time in the rate of movement of the VPI.

The device provides a measurement of geometrical parameters of the track with high accuracy due to the presence of two overlapping groups of sensors: (RK 1+ RK 2) and (BK 1+BK 2+HQ 1+HQ 2), and output information from each of the groups is processed offline.

The proposed method of condition monitoring of railway track and a device for its implementation allow to measure the true (within instrumental error sensors) geometrical parameters of the track, with which the population of partial derivatives - deviations of geometrical parameters of the track from the set - drawdown, straightening, levels and so on , but also more sophisticated complex characteristics of the dynamic interaction between the track and. rolling stock.

Measurement of geometrical parameters of the track during movement of the VPI speed up to 250 km/h allows the rate of movement analysis and evaluation of the condition of the track, but also to justify planning for its repair. The above leads to the practical applicability of the invention.
