Definitions
- the invention relates to a system for detecting the surface of a track, comprising a rail vehicle, a surface scanner and an evaluation device.
- the invention relates to an arrangement for use in the system and a method for operating the system.
- a number of systems and methods for detecting surface structures of a stretch of track are known from the prior art, with a surface scanner being used.
- AT 519739 A4 discloses a method with a surface scanner arranged on a track construction machine. The surface data recorded in this way is used to detect objects on the track and to derive specifications for automated control of the track maintenance machine.
- AT 520291 A4 discloses a system and a method in which adjacent devices on a track are detected by means of a surface scanner. Devices with a known geometry, for example a platform edge or an overhead line system, are subsequently used as reference objects for determining a track position.
- AT 520526 A4 describes a rail vehicle and a method with a surface scanner for detecting surface points of a track.
- An inertial measurement system for detecting a trajectory of a track course is arranged on a first measurement platform.
- the surface scanner is arranged on a second measuring platform, on which a second inertial measuring system is located to record a further trajectory. With the recorded trajectories, the surface coordinates recorded by means of the surface scanner are referenced to the course of the track. 2
- the invention is based on the object of improving a system of the type mentioned above compared to the prior art in such a way that more versatile and more efficient use is made possible. In this case, a correspondingly improved arrangement is to be used. It is also an object of the invention to specify a correspondingly improved method for operating the system.
- a receiving device for temporarily fastening and connecting the surface scanner is arranged on the rail vehicle, with a connection device coupled to the receiving device for the evaluation device being arranged in an operating cabin of the rail vehicle, and the evaluation device in a portable housing with power and data connections for temporary Connection is arranged with the connecting device.
- the permanent system equipment of the rail vehicle is limited to the recording device for the surface scanner, the connection device for the evaluation device and the cabling or other coupling of the two devices.
- the rail vehicle is thus prepared for immediate use of the system, with the surface scanner and the evaluation device not having to be carried along permanently.
- the surface scanner is only mounted in the cradle when in use.
- the housing with the evaluation device is also only carried along during a corresponding measurement run. When the rail vehicle is operated in other ways, these system components can be used for other purposes. Replacing these system components with newer versions is also considerably simplified with the system according to the invention. The same applies to the replacement of defective system components.
- the surface scanner is designed as a rotary laser scanner, with the surface scanner in particular forming a unit with a connection plate that temporarily 3 can be fastened and connected to the receiving device.
- the rotary laser scanner provides a high-resolution point cloud of the surface of the track and its surroundings while the rail vehicle is moving forward.
- the connection plate With the connection plate, the surface scanner is locked in the exact position on the recording device.
- the coordinates of the surface points are thus recorded in a predetermined coordinate system that moves with the rail vehicle.
- the connections of the surface scanner are integrated into the connection plate. With the attachment to the receiving device, the data and supply lines are also connected.
- a further improvement provides that an inertial measuring unit is connected to the surface scanner.
- This inertial measurement unit records the movements of the surface scanner in three-dimensional space. The coordinates of the surface points recorded by means of the surface scanner can thus be transformed to a stationary coordinate system.
- the portable housing is advantageously developed in that it comprises a central processing unit as an element of the evaluation device, with an algorithm for evaluating data recorded with the surface scanner being set up in the processing unit.
- the central processing unit is also used to process further input and output data.
- the portable housing includes a network router, with network connections being arranged on the housing.
- the evaluation device can be connected to external devices, for example to a laptop or a printer.
- the connection to the surface scanner is also advantageously carried out via a network connection.
- the rail vehicle comprises a distance measuring sensor for detecting a route, the distance measuring sensor being coupled to the connection device.
- the evaluation device receives a displacement signal 4 of this path measuring sensor to determine the direction of travel and to assign the surface points recorded with the surface scanner to a route along the track section traveled on.
- a displacement sensor that is already installed on the rail vehicle for other applications is used.
- a current collector located on the rail vehicle offers a further advantage, with a control device for controlling the current collector being coupled to the connection device.
- the connected evaluation device is informed whether the pantograph is lowered or pressed against an overhead line.
- This information is used when recording the course of the overhead line using the surface scanner.
- the characteristic of a contact wire for example the height or the zigzag course, is detected by means of a detection algorithm set up in the evaluation device.
- a contact force between pantograph and contact wire can also be derived.
- the rails are also detected in the course of the point cloud analysis, the position of the contact wire can be directly related to the standardized measuring points of the upper edge of the rail.
- the detection takes place at high driving speeds. With the acquisition of a high-resolution point cloud, special cases such as double contact wires can also be detected.
- An advantageous extension of the system includes a second rail vehicle with a receiving device for temporarily attaching and connecting the surface scanner and with a connection device for the evaluation device.
- the surface scanner and the housing with the evaluation device can be used alternately on both rail vehicles.
- the housing which includes the evaluation device, has at least one handle.
- the housing is thus similar to a suitcase that is set up as a portable unit for use in one of the systems described.
- the suitcase-like housing includes an additional storage compartment in which the 5
- a method according to the invention for operating the system comprising at least two rail vehicles provides that the surface scanner and the evaluation device are operated with the first rail vehicle, that the surface scanner and the housing with the evaluation device are then removed from the first rail vehicle and attached to the receiving device and the connection device of the second rail vehicle is connected and that subsequently the surface scanner and the evaluation device are operated with the second rail vehicle.
- several rail vehicles that regularly run on different track sections can be used to record these track sections with just one surface scanner and one evaluation device.
- the rail vehicle 1 shown in FIG. 1 is, for example, a railcar or a track construction machine with a front end 2 that is free at the front.
- Such vehicles are generally used for purposes other than detecting a track surface. Their use within the scope of the present invention is particularly advantageous because a track measurement can be carried out during regular operation of these vehicles.
- a measuring vehicle itself can also be useful as a carrier vehicle in order to supplement existing measuring systems with surface detection.
- the rail vehicle 1 advantageously includes its own drive.
- a vehicle frame or vehicle body 3 is connected to rail carriages 4 6 a track 5 movable.
- An operator's cabin 6 is constructed on the end face 2 .
- a pantograph 7 is arranged on the roof of the rail vehicle 1 .
- the rail vehicle 1 is supplied with electrical energy via this pantograph 7 when the overhead line 8 is present.
- a hybrid system is provided which ensures the operation of the rail vehicle 1 even if the overhead line 8 is missing or switched off.
- the rail vehicle 1 also includes an internal combustion engine or an electrical energy store.
- the rail vehicle 1 is equipped with system components for detecting surface structures of a track section that is being traveled on.
- a surface scanner 9 and an evaluation device 10 are designed as mobile system components. These are not permanently installed, but can be temporarily connected to the rail vehicle 1 by means of easily detachable connections.
- the surface scanner 9 can be fastened temporarily to a receiving device 11 on the end face.
- the evaluation device 10 is arranged in a portable housing 12 and can be placed on a connection device 13 in the operating cabin 6 .
- the housing 12 includes a handle 14 in order to be able to transport the evaluation device 10 easily and safely.
- a contact unit 15 with power connections 16 and data connections 17 which are brought into contact with corresponding connections of the connection device 13 is located on an outside of the housing 12 .
- power sockets are also arranged on the housing 12 in order to connect peripheral devices if necessary.
- the receiving device 11 and the connecting device 13 are permanently arranged in the rail vehicle 1 and are coupled to one another, for example via a bus system.
- rails 18, sleepers 19, rail fasteners 20, a ballast bed 21, platforms 22 and elements of the overhead line 8 are recorded in particular. These include a contact wire 23, a suspension cable 24, masts 25 and fasteners.
- the rail vehicle 1 includes a path measuring sensor 26 for detecting a route s 7 arranged on an axis of a rail undercarriage 4, a rotary encoder (encoder) for detecting an angular velocity.
- a rotary laser scanner is advantageously arranged as the surface scanner 9 (e.g. a laser from RIEGL Laser Measurement Systemstechnik m.b.H. with the designation VUX-1HA).
- Such surface scanners 9 deliver a point cloud with a high resolution by means of a rotating laser beam 27 reflected from surfaces.
- the surface scanner 9 is coupled to an inertial measurement unit 28 .
- This inertial measuring unit 28 registers changes in the position of the surface scanner 9 with respect to a stationary coordinate system. A coordinate transformation of the recorded point cloud can thus be carried out in a simple manner.
- a computing unit 29 (e.g. Programmable Automatic Controller, PAC) is installed in the portable housing 12 as an element of the evaluation device 10, in which an evaluation algorithm is set up.
- the arithmetic unit 29 is coupled to an interface converter 30 (e.g. RS422 converter) and the contact unit 15 via an internal bus.
- the housing 12 includes a DC voltage converter 31 which converts a supply voltage of the evaluation device 10 into a supply voltage of the surface scanner 9 .
- An output line is routed via an operating element 32 arranged on the housing 12 in order to switch the power supply of the surface scanner 9 on and off.
- External devices can be connected to the housing 12 via a network router 33 (e.g. Ethernet router) and network connections 34 and other interfaces 35 (e.g. USB). These are, for example, a printer 36 and a laptop 37 for inputting and outputting data. For example, parameter adjustments or software updates are possible. Currently recorded data can be displayed on the screen of the laptop 37 .
- a touch panel PC 38 is optionally installed in the housing 12 in order to enter and display data.
- a data memory 39 can also be connected. By storing the data recorded by the system, the following 8th
- evaluations possible For example, following measurement runs that have already been carried out, evaluations can be carried out in a remote system center, with corrections being applicable for even more precise results.
- a web-based software solution offers a user further options, for example the creation of an electronic report that takes various specifications of valid standards into account. This is particularly advantageous for using the system on track construction machines, because changes made to track 5 with working units can be detected by means of surface scanner 9 and can subsequently be documented.
- the evaluation device 10 can be connected to a power supply 40 of the rail vehicle 1 via the connection device 13 .
- the housing 12 advantageously includes an energy store 41 which can be charged via one of the power connections 16 .
- the energy store 41 is an element of an uninterruptible power supply. With the energy store 41 charged, the evaluation device 10 can also be activated outside of the rail vehicle 1, for example in order to make parameter changes or carry out software updates.
- connection device 13 is coupled to a control device 42 of the rail vehicle 1 .
- status data of the rail vehicle 1 can be supplied to the evaluation device 10 .
- the evaluation device 10 receives a notification signal which shows whether the pantograph 7 is raised or lowered. This information is used when detecting the position of the contact wire 23 by means of the surface scanner 9 . In particular, a change in position as a result of a contact pressure of the pantograph 7 is registered.
- the recording device 11 advantageously comprises a console with positioning elements 43 and locking elements 44 for fastening the surface scanner 9 in a precisely defined position.
- the surface scanner 9 includes its own housing 45 in which a laser interface 46 is set up.
- the surface scanner 9 can be connected to power and data connections 16 , 17 of the recording device 11 via a dedicated contact unit 47 .
- the contacts are plug-in connections in a connection plate 48 of the surface scanner 9 9 trained. In the course of temporarily attaching the surface scanner 9 to the receiving device 11, the power and data connections 16, 17 are each automatically contacted.
