    The invention relates to a provision for the marking and measurement of railroad sections for the purpose of maintaining railroad tracks, in particular in the area of needles, railroad changes, curves and other railroad sections susceptible to wear.
    In the state of the art, railroad inspections are carried out to determine maintenance areas in many different ways. In this case, automated measurement with measurement traces for critical wear areas is generally not sufficiently accurate to directly control the exact processing by means of machines (grinding machines or shoeing machines). Therefore, there is a need to be able to reproduce the exact local measurement of processing areas during the maintenance of the railway not only reliably, but as far as possible, also carry out tests coupled with the working machine. Currently, the computerized measuring devices used so far - in particular, for the complicated areas of the railway line, for example, curves or needles - are not reproducible in a sufficiently accurate way, with respect to the position of a processing area, if the area of the railway line is crossed several times with a working machine, and the processing must always be employed, in turn, exactly at a certain point (in advance by rail profile measuring devices).
    A measuring device that makes it possible to inspect, in sections of the railway line, such as curved areas, the status of railway lines in the railway is described in document DE 32 10 015 C2. In this case, it is a manually operated measuring device for the measurement of railway lines according to their lateral position and altitude, which using two position ropes, which at a defined interval are performed as a detachable tripod stationary with leveling bubbles, alignment optics and measuring bars, and which has a positioning base with crosspiece for placement on the two rail bars. In the case of large intervals, this measuring device measures the position of the railroad along a large rope of the curve arc, and for the verification it needs the measurement positions and the position of the railroad track found with this, it additionally requires the reference to fixed points (for example, pillars), which need to be specified by the route network operator. A free fixation, corresponding to the state of the railway line determined from railway line positions, is therefore not possible for maintenance of the railway line of the rail bar.
    Another measuring device for the inspection of rails, in particular needles, is known from EP 1 548 400 A1. In this case, with a laser rangefinder and a fiber optic conductor, which projects the laser beam over the point to be measured, as well as with a CCD receiver it is detected at the point to be measured at the distance from the track.
    Apart from the fact that the measuring device mentioned above uses optical sensors, and for this reason it is no longer suitable for use on work machines such as grinding machines, EP 1 548 400 A1 on fixing and The recognition of the individual measuring points (which can be in the range of 2 to 5 mm) discloses that these points are recorded on the path traveled by the impellers of the measuring device in an angular rotation transmitter, and are coordinated with the results of the measurement. measuring points meter. Due to sliding, in particular, movements from side to side in the area of curves, this definition of the measuring position cannot be reproduced exactly, in such a way that the coordination for the control of the places of use of a machine work is insufficient. In addition, the angular rotation transmitters contain systematic errors, which in each movement back and forth in the work area, due to sliding of the wheel cause an accumulation of errors.
    If a non-contact position detection is to be carried out, visual recognition capability is actually desirable, but soiling through the working machines impairs the position recognition of the measuring points, so that visual processes cannot be employed in the direct interaction with working machines (for example, track grinding machines). A measurement device for the discovery of measurement sites, which have been found or are defined by regulations for measurement or processing, therefore need to be designed in such a way that they are in a position to record along the track, position indications, reliably and reproducibly, which cannot be tampered with by environmental conditions.
    Therefore, the invention has the task of finding a new possibility for the marking and measurement of sections of the railway line, for the purpose of maintaining railroad tracks, which allows a reliable definition and exact position of susceptible railway sections. to wear such as, for example, curves and needles, also in direct interaction with working machines, without the need to disconnect the processing of rails for measurement, or another decoupling of processing and measurement.
    According to the invention, the task is solved with a provision for marking and measuring sections of railway lines for the purpose of railroad track maintenance, in which means for the optical detection of measuring points are available, due to the fact that a sensor unit, for the detection of measuring points that are next to a track, has at least two independent detection units that measure without contact, based on several measurement principles, being that, a measurement principle contains an optical sensor, with spectrally selective sensitivity and a second measurement principle contains an identification detector, for the individual identification of measuring points, due to the fact that the measuring points as angle elements have at least , two flaps, a first flap vertically aligned is removably attached to the rail, and a second flap horizontally aligned, are equipped with a cover then narrowband spectrum transmitter for the spectrally selective sensor, as well as, with an identification detection support for the identification detector, and the fact that the sensor unit is placed in a device that can be moved on the line railway, in such a way that the independent detection units are guided in the same direction through the measuring points with the movement of the device that can be moved on the railway line, parallel to the track.
    Advantageously, the sensor unit is designed as a transverse sensor unit vertically rotating with respect to the rail.
    Appropriately, in addition, it can be placed transversely in relation to the rail, in order to adapt it to the width of the rail gauge and the alignment of the measuring points in relation to the rail.
    Advantageously, a sensor unit is available for each rail, in the device that can be moved on the railroad track, and the sensor units are arranged in the transverse direction opposite to the railroad track.
    Appropriately, the measuring points are removably attached to the rail by means of a permanent magnet and are preferably placed outside or inside the rail core.
    In this case, there is a possibility that the measuring points are placed on a groove track on the conductor track or on the guide rail of a railway line.
    Preferably, the measuring points are equipped with a luminescence layer as a narrow band spectrum emitting coating. In this variant, the sensor unit advantageously contains a spectrally selective sensor for luminescence light, which is adapted to the emission wavelength range of the luminescence layer.
    Second, the measuring points are equipped with an identification detection support in the form of an RFID chip. For this configuration, the sensor unit appropriately contains a radio wave transducer for reading the RFID chip.
    Advantageously, the device that can be moved on the railway line for fixing the sensor unit is a working machine in the group of track grinding machines or track clamping machines. But this device can also be a simple measuring vehicle.
    The invention is based on the basic reflection that, the well-known rail measuring devices define the areas of deficiency determined or outside and independent of the rail extension through fixed points (for example, pillars), or, however, on the railroad require a optical detection of delicate measurement marks (for example, bar codes or the like), or define the position indirectly via wheel-driven angular transmitters. In the two cases mentioned last, traditional dirt affects the measurement of optical or mechanical position due to the processing of the track (for example, grinding), which, however, is indispensable for the accurate recording of the measured value.
    In the case of the invention, this problem is solved through the use of appropriate marking elements (hereinafter abbreviated as "measuring points"), which are positioned provisionally or also permanently on or near the railroad tracks, and whose properties they are obtained in such a way that they can be recognized both actively and passively without contact by means of a measurement system attached to a track vehicle, and can be detected with sufficient accuracy.
    The invention consists of the combination of specially produced measuring points and a multi-sensitive sensor unit belonging to them.
    The entire measurement system for a section of the railway line to be processed has an infinite number of “mobile” measuring points, and the preferably removable fixation takes place by means of a permanent magnet, directly on a lateral surface of the web. the rail. In order to be able to use the measuring points also in the construction of a closed railway line (covered railway line in the construction of the street) these measuring points are configured in such a way that they can also be fixed without problems on the conductor track (check rail).
    In this case, the positions of the measuring points are determined with the aid of the measurement protocol of a rail profile measuring device, placed before in the section of the railway line, or corresponding to an attached regulation for the measurement and processing, and the measuring points placed in the locations that characterize, for example, the application point and the end point of one or more processing areas for a working machine (grinding machine or chocking machine).
    According to the invention, the measuring points can be recognized (detected) by means of a sensor unit based on at least two qualitatively different measuring principles, the sensor unit being conducted together in an apparatus moving over the railway line. An additional coupling or transmission with a GPS is possible with simple add-ons.
    For detection, two non-contact measurement methods are preferably used together, one of which uses an optical principle that is as prone to interference as possible, using spectrally selective marker dyes (based on photoluminescence), and the another employs a principle of measuring magnetic or capacitive radio waves with the possibility of coding (ID labeling). Both principles can be operated both actively and passively, but preferably at least one active ingredient suitable for ID labeling is used.
    In the case of the optical principle, it is preferable to detect a fluorescent dye, which is sufficiently activated by daylight or by working lighting on a working machine, by means of a spectrally selective optical sensor. , which is adjusted to the emission wavelengths of the fluorescent dye. This ensures position recognition and mistakes or ambiguities of other reflective objects are excluded.
    Preferably, the measuring point is equipped with an RFID (radio-frequency identification chip) chip. This chip serves for the identification of the optically detected measuring point, and represents the “counter” or classification of the processing areas (which can also be “non-processing areas”) of the section of the railway line to be maintained.
    With the invention as a combination of two different measuring methods, applied to appropriately configured measuring points (marking elements), it is possible to carry out a marking and a measurement of sections of the railway line for the purpose of the maintenance of railway tracks, which allows a reliable definition and exact position of sections of the railway that are susceptible to wear also in direct interaction with the working machines, without, for this, it is necessary to disconnect the processing of the tracks for the measurement, or another decoupling of processing and measurement. The sensor system according to the invention results in an unambiguous definition of the position of all measuring points, their correct sequence, the elimination of ambiguities and repeatable repeatable accuracy at various crossings (elimination of wheel slip). The invention should be clarified in more detail below, with the aid of execution examples. The drawings show: In fig. 1: a schematic representation of a measurement point on a Vignol track; In fig. 2: the arrangement of the measurement points in the area of a needle (with change of railway line); In fig. 3: the arrangement of the measuring points in the area of a needle (without changing the railway line); In fig. 4: side view of a working machine with the sensor unit attached at the rear; In fig. 5: front view of a working machine with a rotating sensor unit; In fig. 6: front view of a working machine with a displaceable sensor unit. External fixation (Vignol rail); In fig. 7: front view of a working machine with a displaceable sensor unit. Internal fixation (groove rail); In fig. 8: front view of a working machine with a displaceable sensor unit. Internal fixation (in the groove rail); In fig. 9: schematic representation of a measuring point on a groove rail in the area covered with a magnet, which is executed as a short flange of the angle element for fixing the measuring point; In fig. 10: representation of the method of operation of the detection of the measuring point for the control of the working machine, with the aid of the registered measuring points; In fig. 11: representation of the method of operation of the detection of the measurement point for the recording and processing of data from working machines using GPS. The arrangement according to the invention, in its basic assembly - as shown schematically in fig. 1 - it consists of a measuring point 3, removably placed on a track 1 (here designed in a stylized way as Vignol track), through which a sensor unit 2, which is fixed on a work machine 8 , is guided away. Sensor unit 2 consists of two independent detection units, which are based on different principles. The first detection unit is an optical sensor (I), which can record spectrally selective irradiation over a limited reception range (with, for example, 2 cm in diameter with an interval of up to 25 cm), and is adjusted to an irradiation narrowband spectrum emitted by measurement point 3.
    The second detection unit is designed for a defined ID recognition and is preferably a radio wave II transducer, which can read the programmed recognition of an RFID 6 chip. Its range is designed for about 10 to 30 cm, and is limited to a transmission and reception cone approximately equal in size.
    The measuring point 3 adapted to this sensor unit 2 consists of an angle element 4 (for example, a metal such as steel, stainless steel, brass, or the like, a stable synthetic material or material compound, such as CFK, GFK, AFK or SFK, or other durable and stable materials). The angle element 4 has at least two flaps, of which a permanent magnet 7 is attached or embedded in a short flap 41, and a luminescence layer 5 (preferably made of material) is attached to a long flap 42. fluorescent or phosphorescent) on the upper side, with the outer side of the long flap 42 facing upwards towards the sensor unit 2. In addition, the long flap 42 of the angle element 4 contains the RFID chip 6 containing ID recognition, which can be read by the radio wave transducer II. In special developments, in the long flap 42, short flaps 41 can also be expanded, in such a way that a T-shaped angle element 43 results (as shown in fig. 5).
    While the optical sensor I, preferably, when detecting a fluorescent dye as a luminescence layer 5, which is sufficiently activated by daylight or by the working illumination of the working machine 8, registers a very narrow reception range (from about 6 to 8 cm), and thereby ensuring sufficient position recognition, the radio wave transducer II is competent for the identification of measurement point 3 and, therefore, a detector in the direction of a “ counter ”or a classifier for the interpretation of the processing range that follows measurement point 3 for working machine 8. For this purpose, each measurement point 3 is equipped with an RFID chip 6, in which a specific program is programmed. ID recognition.
    The simplest “counter” coding consists of the alternate assignment of one of the O / L encodings of measurement points 3, with “O” characterizing the position of use and “L” the final position for the processing ranges individual working machine 8.
    If the section of the railway line to be maintained, in which the working machine 8 passes and processes (repeatedly) back and forth, has an infinity of processing ranges, divergent or extended digital recognitions can be programmed for the production of the coordination unambiguous measurement points 3 on the RFID chip 6.
    Measuring point 3 is preferably detected passively and actively by means of the sensor unit 2 moved with the working machine 8 through the rail section. In the detection, two non-contact measurement methods are used in order to combine an optical principle that is as prone to interference as possible, by using a coating (luminescence layer 5), a narrow band spectrum emitter, to define the exact position in the railway line, with a radio wave transducer II, which determines the unambiguous purpose of measurement point 3, and at the same time excludes that an external signal registered by optical sensor I can additionally be mistaken as measurement point 3.
    Alternatively, magnetic or capacitive measurement principles can also be used to detect ID recognition.
    As a result, the sensor system according to the invention results in an unambiguous definition of the position of all measuring points 3, their correct sequence, as well as the elimination of ambiguities and reproducible repetition accuracy of the measurement point record in several crossings (elimination of error positions caused by sliding of the wheel).
    Measuring points 3 can be used for different railroad markings, arranged and reorganized according to need, as well as being reused so often, that during modifications or disassembly (repair work) they can be used in construction sites or between them, which can be coordinated several times and always unequivocally.
    In the case of surface damage (dirt, mechanical influence), the coating (luminescence layer 5) can be renewed simply (for example, by means of a fluorescent spray) directly on the site at the construction site. The measuring points 3, therefore wear-proof, as the RFID chip 6 is not damaged, and the signals from the measuring points 3 can be reproduced, as long as the measuring points 3 are not moved by mistake along track 1.
    Measuring points 3 are preferably made as angle 4 elements, with a width of 2 to 8 cm (preferably 4 cm), and have flap lengths between 2 to 6 cm (preferably 3 cm) , for the short flap 41, and 10 to 20 cm (preferably 12 to 15 cm) for the long flap 42. In this case, the short flap 41 can also be replaced in whole or in part by the permanent magnet 7, or the long flap 42 branch two short flaps 41 to both sides, such that a T shape results. For the resolution of the position of the measuring points 3 - even in the case of a width of the angle element 4 totaling several centimeters - no it is no problem to maintain a positioning accuracy of 1 cm, because due to the detection of center or corners in the recorded optical image of measurement point 3 this accuracy can be determined simply and accurately.
    Since no visual recognition capability is required (no high resolution point detection), normal dirt does not affect the position recognition of measuring points 3 by optical sensor I. In order to maintain processing dirt (for example , grinding dust) at the limits, however, additional air currents may be introduced, preferably through nozzles (not drawn), in the gap between measuring point 3 and sensor unit 2. The measuring range in detection units (optical sensor I and radio wave transducer II) are between 10 cm and 30 cm, with an optimum value of about 15 cm.
    The entire measurement system for a section of the railway line to be processed has an infinity of measuring points 3 “movable”, which are fixed in a simple way, provisionally on the rails or in the proximity of the rails of the railroad 1, being that, the fixing takes place reliably, by means of a permanent magnet 7, directly on a side surface of the respective rail 1. In order to be able to use the measuring points 3 also in the construction of closed railway line (covered railway lines) these measuring points they are configured in such a way that they can also be fixed, without problems, on the conductor rail (check rail). The fixing is preferably carried out on the outside of the railway line, as shown in figures 5 and 6. There are, however, several special railway line sections, which require placement on the inside of the railway line, or also in a conductor rail (check rail), or on a guide rail (guard rail), as shown in figures 7 and 8. In figures 2 and 3, the handling of such an arrangement described above is represented, and for reasons of clarity only measuring points 3 are drawn in the area of a needle's railway line.
    Prior to the processing of the railway line by the working machine 8, on the basis of the states of rail wear determined previously, or of specified processing tasks, in defined sections of the railway line, defined processing areas are established, and the measuring points 3 are correspondingly positioned. The positions are read by means of the sensor unit 2, which processes data, stores and makes available for the automatic control of the working machine 8. In fig. 2, several processing areas are represented during the maintenance of the railway, in a section of the railway with a needle, which is adjusted to a change of railway line to the left (path S in curve). In this case, as processing areas B and C, the measurement point positions from 0L to 1L, from 1L to 2L and from 2L to 3L must be detected on the left rail 1, while on the right rail 1, the sections from 0R to 1R, from 1R to 2R and from 3R to 4R are processing areas, and the section from 2R to 3R is an A area without processing.
    The individual processing areas of the represented railroad section, in this case, can be specified as follows: A - unprocessed area (passage only) B - partially processed area (needle section) C - area with constant processing rail surface (grinding a complete section of the path). In fig. 3, the path at the exit in straight line I is adjusted through the needle (without changing the railway line). In this case, the areas from 0L to 1L, from 1L to 2L result, as well as from 3L to 4L as active B and C processing areas. On the right rail 1, in the needle area in the section from 1L to 2L, the head of the rail 1 should only be partially processed (area B), while the processing is interrupted between 2L and 3L (passive processing area), that is, the grinding bodies (not drawn) of the working machine 8 are in a safety interval in relation to the rail 1, so that the needle is not damaged. At the position of the 3L measuring point, processing resets, and takes place up to the 4L position. On the right rail 1, in the sections from 0R to 1R, as well as from 2R to 3R the head of the rail is completely processed, whereas between the measuring positions 1R and 2R it is only partially processed.
    This way of working can be repeated as many times for each track 1, and it does not matter whether the area is traversed forwards or backwards by the working machine 8 with the sensor unit 2, since the measuring points 3 ensure unequivocal position and area coordination.
    This method of exact control of the working machine 8 can be used in each and every section of the railway, in particular, also inside needles. In this case, the risk points, which, therefore, cannot be damaged, are marked and through the exact position recognition by means of the sensor unit 2, error-free processing of the track 1 takes place. The exact and unmistakable registration of the points of In this case, measurement 3 also allows the processing of several successive needles in any way. Fig. 4 shows, in a side view of the working machine 8, that the sensor unit 2 is placed in the front or rear area of the working machine 8. A correspondingly displaced view around 90 ° of a front or rear area of the working machine 8 in fig. 5 shows that, in the case of measuring points 3 placed externally on the railway line, the detection units I and II (optical sensor I and radio wave transducer II) are advantageously implemented as a rotating sensor unit 21 , in order to keep that unit protected outside the measuring and processing regime of the working machine 8, preferably in a carcass niche (not drawn), for example, when the working machine 8 is moved from a construction site. works for the next.
    In addition, fig. 5 shows another way of executing the measuring points 3, in which angle elements 43 are placed outside the rail web 1. In this case, the short flaps 41 placed in the web can also be formed by the permanent magnet 7, while the flap long 42 is glued directly to the permanent magnet 7.
    Figures 6 and 7 show a preferred configuration of the invention, in which the detection units I and II are carried out as a sensor unit 22 which can be moved on the railway line transverse to the direction of the railway line. In this case, fig. 6 represents the position extended along a crosspiece 9 of the displaceable sensor unit 22, for recording the measurement points 3 placed outside the tracks 1, while fig. 7 shows the retracted position for measurement points 3 fixed inside a groove rail 11. In the case of this fixation, the check rail is used for placing measurement point 3 by means of magnet 7 (in this case, not designed for simplification).
    A similar situation is shown in fig. 8, and in this case, a section of the railway line in the form of a covered construction necessarily requires the placement of measuring points 3 on the check rail of the groove rail 11, since other fixation possibilities are not available. disposition. Because of the narrow space conditions often prevailing there beside the groove track 11, it is sometimes necessary to adapt to the shape of the measuring point 3.
    Such a modification of measuring point 3 is shown in the enlarged representation of fig. 9. In this case, the measuring point 3 is changed in such a way that, preferably, it is located directly on the street construction (covered area 12), and through the permanent magnet 7 it is fixed with lock due to the force on the rail groove rail conductor 11. Figures 10 and 11 show a schematic representation of the operation of the detection of the measuring points 3 as a data transfer scheme for the direct control of the working machine 8, and for the integration of the recorded data using a GPS. The signals from the measuring points 3 registered via the sensor units 2 are sent, appropriately, through an interface, to a computer unit (PLC), and continue to be processed there, in order to carry out processing steps. concrete directly on the working machine 8. In fig. 11, with an equal record of measurement data according to the PLC, a modem is connected in order to prepare via satellite the data (coordinates of measurement points 3 and measurement values) available worldwide in other locations (appropriately via the Internet, to a receiving station with the corresponding access data).
