This application is nepredvidatelne application seeking priority based on provisional application U.S. No. 60/584,769, entitled, "System and method for control of the railroad tracks," John Nagle's (John Nagle) and Stephen Orrell (Steven C. Orrell), filed June 30, 2004, included so here by reference in full.

The technical field to which the invention relates.

The present invention generally relates to a system and method for monitoring railway tracks and, in particular, to a system and method for monitoring the parameters of railway track using a laser, camera and processor.

The level of technology

Railways are usually built on a base layer of compacted, crushed stone material. The ballast layer of gravel on top of this layer of stone. Sleepers laid in this gravel layer, and two parallel steel rails attached to the sleepers fasteners. The most used sleepers made of wood. In the manufacture of sleepers used various other materials, such as concrete, steel and composite or recycled material. These sleepers from alternative materials represent a relatively small percentage of all sleepers. Sleepers support a rut or transverse distance between the rails. Ø the Aly distribute the load on the axis from trains on the gravel layer under the sleepers and contribute to the damping effect of the whole structure of the way. Over time, environmental factors can lead to poor sleepers as they do not have to be replaced. Every year, on the Railways of North America replace up to 2% or more of all wooden sleepers. This amounts to several million sleepers.

For logistics management replacement of sleepers and quantify the need for new sleepers, crawlers ways of trying to classify the condition of sleepers and fasteners on a regular basis. This classification is most often performed through visual inspection to identify sleepers and fasteners that are rotted, broken, split, or worn to such an extent that their life is coming to an end. The process of visual inspection is very time consuming. In practice, the control path is performed by the crawler along the way to monitor and record the condition of sleepers and/or fasteners, which are spaced approximately 20 inches along the way. On one particular North American railway was established that a team of 3 or 4 people can examine only 5 to 7 miles a day.

Device for inspection of rails is known from the prior art, and software for analyzing and organizing data, obtained through such devices known from the prior art. For example, Tielnspect® ZETA-TECH Associates, Inc., New Jersey not only is em a computerized control system sleepers, having a handheld device and software. A handheld device used by crawlers to walking path and the survey path, and the software used to analyze and organize the data received from the device.

In addition to the classification sleepers, other components of the path must be checked periodically for wear and deterioration. This includes the wear of the rail surface, integrity, anchors and fasteners, alignment of rail pads, the condition of the gravel layer and the gauge between the rails. As with the classification of the sleepers, the control of these parameters rail can also take a long time. The prior art system for testing of rails. For example, omniSurveyor3D® from Omnicom Engineering, United Kingdom, this is the system for investigation of railway infrastructure. In addition, ENSCO, Inc., Minnesota provides a laser system for measuring gauge for measuring the gauge between the rails with lasers.

The present invention aims to overcome or at least mitigate the influence of one or more of the above problems.

Detailed description of the invention

Figure 1 and 2 shows a variant implementation of the system 30 for monitoring railway track according to some ideas of the present disclosure. Figure 1 is disclosed a control system 30 is shown schematically relative to the railroad tracks. Figure 2 plot of the disclosed inspection system 30 is shown in perspective considers the flax railroad tracks.

According to Figure 1, the disclosed control system 30 includes a light source such as a laser 40, a device for receiving light reflected from a controlled area, for example the camera 50, and the processing device 60. In the implementation shown in figure 1, the disclosed control system 30 is used for examination of paintings railroad tracks. Although the disclosed system and associated methods of control described with reference to use to control the railroad tracks, from this disclosure, it is clear that the disclosed system and method can be used in other areas and industries where you want to control surfaces or components. For example, the disclosed system and method can be used to monitor roads, transmission lines, pipelines or other networks or systems.

Canvas includes 10 sleepers, rails 12, rail pads 14, crutches 16 and gravel layer 18. In the General case, the laser 40 projects a beam of laser light 42 onto the canvas. The beam 42 creates a line projection L, shown in figure 2, on the canvas, which follows the contours of the surfaces and components of the canvas. The receiver of light, the camera 50, captures the image of a line L of laser light 42 is projected on the canvas. The camera 50 transmits the captured image to the processing device 60 for processing and analysis that Bo is it described in detail below.

According to Figure 2, a pair of laser 40 and the camera 50 are located above each of the rails 12 of the road. Lasers 40 and camera 50 can be assembled into a rigid structure 32, which may be mounted on the test vehicle (not shown) or other device moving along a path, to maintain the control system 30 in the correct position. In figure 2, for simplicity, shows only the design phase 32. However, it is obvious that other known structural components 32 may be needed for mounting lasers 40 and 50 cameras to control the vehicle.

In General, the control, the vehicle may be any suitable means of transportation for travel on railroad tracks. For example, in the technique is widely practiced supply of conventional road vehicles, such as truck, "rail" chassis mounted on the vehicle frame. Rail chassis typically includes a set of small railway spare wheels that allow road vehicle to travel along the rails. According to one variant of implementation, structure 32 of the disclosed inspection system 30 can be mounted on the platform of the truck with rail chassis. Alternatively, the control, the vehicle may be an equipment maintenance of way (MoW), is AutoRAE specially designed to work on railway tracks. In addition, the disclosed control system 30 can be mounted on a chassis that is towed behind a vehicle, or can be mounted on the locomotive or freight vehicle.

According to Figure 2, the lasers 40 projecting beams of light 42, having a predetermined angular divergence β. Angle of divergence β of the two lasers 40 cover essentially the entire surface of the canvas. Thus, the lasers 40 are creating a line of projection L, which is essentially straight and runs essentially from edge to edge. Each laser 40 preferably generates a beam 42 having an angular divergence β of about 60 degrees and covers approximately half of the canvas. Preferably, the lasers 40 projecting the beam 42 is essentially perpendicular to the surface of the road. Alternatively, you can use a single laser, located so as to create a line of projection of L from edge to edge of the canvas.

In addition, lasers 40, preferably, are infrared lasers with a 4-watt optical output and generating light in the infrared range of about 810 nm. Relatively high optical output of the laser 40 helps reduce the effects of external light without the use of screens. Suitable laser for the disclosed inspection system 30 includes a laser Magnum, production Stacker Yale. The above parameters of the lasers 40 suppose the equipment for monitoring the surface of the railroad tracks. Other implementations of the disclosed inspection system 30 may use an alternative number of light sources, as well as other wavelength, optical output and angular divergence.

According to Figure 2, the camera 50 is located near the lasers 40. According to figure 1, the camera 50 is installed at an angle θ relative to the beam 42 of light projected from the lasers 40. According to one variant of implementation, the cameras are positioned at an angle θ of about 60 degrees. When open, the control system 30 moves along the path, the camera 50 captures an image or a frame of a cloth with small, regular increments. Preferably, the camera 50 is able to shoot with a very high frame rate, for example about 5405 frames per second.

Each still image or frame is captured(initial) cameras 50, then filtered and processed for isolation contoured laser line L is projected on the canvas. Camera 50 is equipped with bandpass filters 52, which pass only the radiant energy lasers 40, essentially, in the preferred infrared range. Because the wavelength of the laser 40 is about 810 nm, bandpass filters 52 chambers 50 can eliminate essentially all external light so that the camera 50 captures essentially pure, fixed line image projection light L from the laser 40.

Each of the two cameras 50 p is reday image data directly to the processing device or computer 60 via communication lines. Preferably, the camera 50 includes a processor 54, the ability to convert or format the captured image of the projection lines of L in the spatial profile that is transmitted directly to the processing device or computer 60. The ability of the camera 50 to process or format the captured image in this way eliminates the need for expensive post-processors or high-speed mechanisms of capturing frames. A suitable camera for the disclosed inspection system 30 having such processing includes Ranger M50 production IVP Integrated Vision Products, Inc.

In addition to the common components, the processing device or computer 60 includes a microprocessor, input device, and output device 62 data storage. The device 62 data storage may include a hard disk, non-volatile storage media, flash memory, tape, or CD-ROM. The device 60 processing may additionally include an input device/display 68, allowing path crawler to enter and view data and to operate the disclosed control system 30. The device 60 processing works with the appropriate programs for the conservation and analysis of various data obtained with the disclosed inspection system 30. For example, the device 60 of the handle can have any under Odysee software for image processing, for example, Matrox MIL, Common VisionBlox, Labview, eVision, Halcon, and IVP Ranger. For example, the device 60 processing may be image processing tools known from the prior art, for analyzing the image data received from the camera 50, for example, tools "area of Interest" (ROI), filtering tools, tools BLOB seekers edges, tools, histograms, etc.

For efficient processing of all data obtained with the disclosed inspection system 30, the device 60 processing, according to a preferred variant implementation, includes a computer with a fast processor such as the Intel Pentium 4 processor with a clock frequency of 2.8 GHz. For efficient storage of all data obtained with the disclosed inspection system 30, the device 62 storage, preferably, includes two hard drives of large capacity, configured to use both mechanisms are read/write as a single drive, which is also known as system redundant array of independent disks (RAID). Fast processor device 60 processing and dual hard drives device 62 storage provide a continuous on-line storage of data obtained with the disclosed inspection system 30. According to a preferred variant implementation, Pete is their for the disclosed inspection system 30 may be provided from the AC source 110 In the form of the generator with a belt drive, attached directly to the engine control of the vehicle.

When the beams 42 are projected on the wrong path surfaces and observed under an angle, the line of projection L, shown in figure 2, the contours of the surface and the components of the canvas. Illustrative image or frame, showing the line of projection L of the blade shown in Figure 3. Data or image frame includes a set of pixels specified in the X-Y coordinates and shows the contour of the blade, captured by the camera 50. By filtering and other image processing methods known from the prior art, the image includes two pixel values, where darker pixels represent the contour of the blade. Each pixel of the specific image data has the same Z coordinate, which expresses a particular position along the path, which were captured image data. Similarly, the set of captured images creates a three-dimensional snapshot of the canvas, in which each image has X-Y coordinates, showing the contour of the blade, and has a Z coordinate expressing a specific position of the contour along the rail.

It is obvious that the speed of image capture is limited by the width and height of the scanned area, the distance between the discrete still images, resolution NEPAD is the author of images the maximum frame rate of the cameras 50, the processing speed of the computer 60 and the write speed of the device 62 data storage. For application of the disclosed inspection system 30 to the Railways, in order of preferred example, the distance between still images or frames captured by the camera 50 is about 0.1 inch, the preferred speed control of the vehicle is about 30 miles per hour, the preferred height of the scanned area is about 10 inches, and the preferred width of the scanned area is about 10 feet across the width of the canvas. To ensure these preferred options the preferred system cameras with a frame rate of about 5405 frames per second, and a computer system with processing speed and write about 8.3 megabits per second. To save each frame or image, for example, shown in Figure 3, can take up to 1,536 bytes. When capturing frames approximately every 0.1 inch along the way, about 633,600 frames will be captured within one mile of the way, and for their storage will need 0,973 gigabytes.

According to another variant implementation, shown in figure 1, the disclosed control system 30 may optionally include a receiver 64 Global positioning system (GPS) to obtain geographic is mestopolozhenii control of the vehicle for controlling the railroad tracks. The receiver 64 GPS may include any suitable GPS receiver known in the prior art for obtaining geographical locations. For example, the receiver 64 GPS can be independent, commercially available device installed on the test vehicle and connected to the device 60 processing using a suitable cable connection and interface input/output. The receiver 64 GPS can receive geographic location using differential or dedifferentiate GPS system. Methods of obtaining essentially the exact data location and time using the receiver 64 GPS is well known in the art and further will not be considered. Geographic location is transmitted to the device 60 processing and can be compiled with image data of the canvas.

When recording of the image data from the camera 50 is also possible to record the geographic location of the frame. Excluding a steady stream of data on geographical location of the receiver 64 GPS to the computer 60, you can free up the processing time of the processor for capturing image data using device 60 processing. Therefore, the receiver 64 GPS, preferably, produces an output to the auxiliary module 65. Auxiliary module 65 compresses the data and transmits it to the processing device or computer 60 is about as necessary. In addition to receiving geographic location data, the receiver 64 GPS can receive data time. In addition, location data and time obtained by the receiver 64 GPS, can be used to determine other variables, such as speed control of the vehicle, which can be used in various disclosed here. Thus, the disclosed control system 30 may use the data from the receiver 64 GPS to start the camera 50 to capture a still image of cloth about every 0.1 inch along the rail.

According to the alternative implementation shown in figure 1, the disclosed control system 30 may include a remote device 66 to obtain the geographic locations of the control of the vehicle when the control rail. Remote device 66 may be an encoder that counts wheel revolutions or partial revolutions, when controlling the vehicle moves along the rail, or may be an existing sensor distance covered on the test vehicle. Remote device 66 may produce location data to the device 60 processing. Using remote device 66, the disclosed control system 30 can start the camera 50 d is I capture a still image of cloth about every 0.1 inch along the rail.

According to another variant implementation, the disclosed control system 30 can capture a still image of a cloth is at or near the maximum frame rate of the cameras 50 without running through a receiver 64 GPS or remote device 66. For example, the camera 50 and the device 60 processing can operate at or near maximum frame rate when controlling the vehicle moves along the path. Using a known average width of 10 sleepers or rail lining 14 disclosed control system 30 can calculate the speed control of the vehicle. The disclosed system may then remove any additional frames to reduce the data warehouse, so that the remaining frames will have an approximate spacing of 0.1 inch. Obviously, the separation accuracy of 0.1 inch is not always possible, but the spacing will be known and can range from 0.05" to 0.1". In this embodiment, the same number of frames must be discarded between each remaining frame in the sleeper, so that the spacing between frames is constant. For example, if the width of rail pads is known and is 8 inches, and for a specific rail lining captured 244 of the frame, the two frames can be discarded each remaining frame. If the entire set of frames numbered from 1 to 244, the remaining frames Bud is t to have rooms: 1, 4, 7, 10, ... 241, 244. The remaining 82 of the frame will be calculated spacing 0,098 inches.

Alternatively, the disclosed system may perform an interpolation between any two captured frames to create a new third frame in any desired location along the path. Some frames can then be dropped to achieve the exact desired spacing between frames.

Once opened, the control system 30 will complete the survey of railway, carried out a computer analysis of the image data. Computer analysis can be carried out by a processing device or a computer 60, placed in the control vehicle. Alternatively, a computer analysis can be performed on another computer system with software for processing images, known from the prior art. Computer analysis involves the search image data and the identification or detection of the places along the path where there are defects or where violated the permissible tolerances of the railway track. For a concrete implementation of computer analysis, you can configure or modify. Geographic location of defects or unacceptable tolerances can be provided so that you can make the appropriate repairs or to schedule appropriate maintenance.

Many measurable the parameters of the railroad tracks is possible to determine or to detect from the image data of the canvas, obtained using the disclosed control systems and related methods. In the following examples are considered some of these measurable parameters and are disclosed various methods of analysis of measurable parameters. Obviously, these and other measurable parameters of the railroad tracks is possible to determine or to detect from the image data of the fabric obtained with the disclosed inspection system. In addition, it is obvious that other methods of analysis of the image data, known from the prior art, can be used with the disclosed system and appropriate control methods. Accordingly, the disclosed system and associated methods of control should not be restricted described herein measurable parameters and specific methods.

For clarity, figure 11 and 12 shows an illustrative compilation of image data obtained with the disclosed inspection system and related methods. Figure 11 shows the aggregate data compiled image showing a plot of sleepers, rail pads and rail in the future. On Fig shows the set of compiled data image showing a more detailed view in perspective. Under 11-12, compiled image data form a three-dimensional representation of (X, Y, and Z) of the region of the canvas. The view has a substantial degree the Yan detail and the various parameters of the components of the canvas can be measured. For example, on 11-12 visible cracks and splitting in the sleeper 10. In addition, the visible height of the sleepers 10 relative to the gravel layer 18. Visible orientation and height of the rail lining 14 and the rail 12. These and other details can be obtained by using the disclosed control system and related methods that are described in more detail below.

In one example, the distance between the sleepers can be determined from the totality of the image data. On Figa-4C shows illustrative frames paintings, obtained with the disclosed inspection system 30 that can be used to determine the distance between the rails 10. On Figa shows the final frame F1 having the first circuit sleepers 10, which is located at the position Z1 along the way. This final frame F1 may indicate the last frame showing the sleeper 10. On FIGU shows the intermediate frame F2, captured some time after the end of the frame F1 and in another position Z2 along the way. In this intermediate frame F2 missing sleepers, because it indicates the position between the rails way. It is obvious that the set of such intermediate frames will follow the final frame F1 shown in Figa. On Figs shows the final frame F3, with the other pole 10', which is in another position Z3 along the way. Computer analysis allows predelete the distance between the rails 10 and 10', for example, first counting the number of such intermediate frames F2, where lack of sleepers. This is the number of intermediate frames F2 can then be multiplied by the known spacing between frames (for example, 0.1 inch) to calculate the distance between the rails 10 and 10'. Thus, it is possible to get essentially the exact measurement between the rails of the canvas, while path crawler does not need to physically control the sleepers. Instead, it uses the image data, forming a three-dimensional snapshot of the canvas.

The determination of whether the frame of the sleeper, you can implement methods of imaging, known from the prior art. For example, according Figa-4C, the contour of the sleeper 10 is expected in the region of interest R frames F1-F3. Computer analysis allows you to search the region of interest R frame for pixels, indicating the presence of sleepers. This can, for example, to average or sum of the pixel values in the region of interest R. Since the circuit sleepers consists of dark pixels, the region of interest R in the frame F1 having the pole 10 will have a higher value of the average or sum than the area R in the intermediate frame F2, where lack sleepers.

In another example of the image data, you can define the corners of the sleepers on the rail. Figure 5 shows illustrative frame rail track obtained with the disclosed system to which ntrolle. The angular orientation of the rails 12 can be represented by the line L1. Line L1 can be estimated, for example, by the methods of the best match or curve approximation, known from the prior art. Similarly, the angular orientation of the sleepers 10 can be represented by the line L2. Line L2 is also possible to evaluate, for example, by the methods of the best match or curve approximation, known from the prior art. These lines L1 and L2 can be averaged from several frames along the Z axis near the sleepers 10. Then computer analysis allows to determine the angular relationship between lines L1-L2 to determine the angles of the sleepers on the rail. This status will indicate the state or worn rail or broken lining wooden sleeper.

In another example of the image data, you can define the gap in the rail. On Figa-6C shows illustrative frames F1-F3 railway track obtained with the disclosed inspection system that can be used to determine the separation of the rail 12. On Figa shows the final frame F1 having the end of the first rail 12, which is located at the position Z1 along the way. This final frame F1 means the last frame showing the rail 12. On FIGU shows the intermediate frame F2, captured some time after the end of the frame F1 and in another position Z2 along the way. In this intermediate frame F2 under the melting rail, because it is the place between the rails way. It is obvious that the set of such intermediate frame F2 will follow the final frame F1 shown in Figa. On Figs shows another end frame F3 has a different rail 12', which is in another position Z3 along the way. Computer analysis allows to determine the distance between the rails 12 and 12', for example, positiva first number of intermediate frames F2, where lack of rail. This is the number of intermediate frames F2 can then be multiplied by the known spacing between frames (for example, 0.1 inch) to calculate the distance between the rails 12 and 12'.

Determining whether the frame rail 12, it is possible to carry out the methods of imaging, known from the prior art. For example, according Figa-6C, the contour of the rail 12 is expected in the region of interest R frames F1-F3. Computer analysis allows you to search the region of interest R frame for pixels, indicating the presence of a contour of the rail. This can, for example, to average or sum of the pixel values in the region of interest. Because the contour of the rail consists of dark pixels, the region of interest R in the frame F1 having the rail 12 will have a higher value of the average or sum than the area R in the intermediate frame F2, where lack of rail.

In another example, the image data can determine the wear of the PE Sov. On Figa-7B shows illustrative frames F1-F2 railway track obtained with the disclosed inspection system, and can be used to determine the wear of the rail 12. Computer analysis can determine whether worn rail 12, for example, determining, less if the distance between the contour of the rail 12 and a reference point in the frame than the same distance in the previous frame. On Figa shown frame F1 with the rail 12, which is located at the position Z1 along the way. The contour of the rail 12 lies in the region of interest R and at the level of L along the Y-axis of frame F1. The contour of the rail 12 is located above the support level L2, which may be the height of the rail lining, measurable distance LD. From the present disclosure specialists in this field it is clear that the reference level L2 may be located in multiple reference points, for example, rail pads 14, crutches 16 or sleepers 10. On FIGU shows another frame F2 in another position Z2 along the way. At position Z2, the distance LD between the contour of the rail 12 and L2 is less than the position Z1. Thus, the frame F2 may indicate wear of the rail 12 at the position Z2 along the way. From the present disclosure specialists in this field it is clear that the wear of rails can also be determined by comparing shots taken at different points in time, but at the same positions along the blade.

In another example of the image data can be in order to determine the defects in the sleepers 10. On Fig shows illustrative frame rail track obtained with the disclosed inspection system. Defects D and D' are shown in the sleeper 10. Computer analysis allows to detect whether the co-sleeper 10 defect, for example, determine are whether the sites D-loop ties outside the region of interest R, or if no plots D' circuit in region R. As shown, the defects in the sleeper may include cracks, splits or breaks in the sleepers. Using aggregate data of the image near this defect computer analysis can determine the width and length of the defect. For example, under 11-12, a set of image data can be used for estimation of width W and length L of the crack shown on the edge of the sleepers. In some cases, computer analysis can determine the depth of the defect, for example, when the orientation of the defect allows laser light to be projected in the defect and be captured by the camera. According to one variant of implementation, the angle between the laser and the camera can be relatively small, so that the light projecting itself into an in-depth defect may still be captured by a camera located almost parallel to the beam of laser light.

In another example, from the image data, you can determine the distance or gauge between the rails or the length of the sleepers. According Pig, method detection region, known from ur is VNA equipment, can be used to find the edges of the contours of the rail 12 in the frame, and the distance W1 between the edges can be calculated for evaluating the distance between the rails 12. Similarly, the method of edge detection, known from the prior art, can be used to find the edges of the circuit 10 sleepers in the frame, and the distance W1 between the edges can be calculated for the evaluation of the width W2 of the sleepers 10.

In another example, from the image data, you can determine the height of the gravel layer 18 relative to the sleepers 10. According Pig, by the method of linear approximation it is possible to determine the level of the gravel layer 18 and the level of the rails 10, and the difference between these levels can be estimated height HBcrushed stone layer 18 relative to the sleepers 10. In another example, images of train paths can be used to determine the size of the stones in the gravel layer 18. For this you can analyze the area of interest, with a gravel layer 18, and to estimate the size of the stones gravel layer using values of curvature in the path of crushed stone layer 18.

In another example of the image data can be detected speakers crutches. Figure 9 shows illustrative frame rail track obtained with the disclosed inspection system. To determine whether the speaker crutch, the region of interest R can be analyzed to determine, is what I do in the field of R plot outline, representing the speaker crutch 16.

In other examples, the image data can be detected missing rail lining, misaligned rail lining or deposited rail lining. Figure 10 shows illustrative frame rail track obtained with the disclosed inspection system. Missing or settled rail lining can be detected, for example, by analyzing the region of interest R and determining whether a portion of the path representing the rail lining in the area of R. Misaligned rail lining, you can determine, through a linear approximation of the portion of the path rail lining and comparing, for example, the orientation of the line with the orientation of the sleepers.
