    Device for detecting relative movements in a vehicle
    Technical area
    The invention relates to a device for detecting relative movements between or of components of a vehicle, in particular in rail vehicles, railways, aircraft and / or chassis of rail vehicles, aircraft, etc.
    State of the art
    In the evaluation of vehicles, especially rail vehicles, but also aircraft, safety, availability and ease of maintenance are usually considered as essential criteria. Especially with regard to the development of high-performance and high-speed rail lines, these characteristics are becoming increasingly important for a vehicle. Since speeds of between 200 and 400 kilometers per hour can be achieved on such high-performance lines of a vehicle, for example, safe and proper functioning of the vehicle, in particular of the chassis, is particularly important there.
    As a chassis while a totality of all moving parts of a vehicle is referred to, through which a connection to the roadway or to the track is guaranteed.
    In a rail vehicle are transmitted by the chassis, which is also referred to as a drive, occurring between the track and the vehicle forces and supported the vehicle in the track. Also, minor bumps in the track are absorbed by the chassis and passed only reduced to the vehicle, whereby the smoothness is improved. A chassis of a rail vehicle, in particular a 201015552 2
    · · · Ι ι
    Railway chassis, which usually includes the so-called wheelsets, the wheelset bearings and a suspension and thus consists of several different components, which can be connected to each other via connecting means (e.g., screws, etc.).
    For example, if due to e.g. A load during operation connections between vehicle components, in particular in the area of the chassis, has been relaxed, so changes in position of these components and / or relative movements between these individual components may occur. Relative movement here means that of a first component in relation to a second component, with this example. is connected, a mostly unwanted movement is performed. Such relative movements and changes in position can thus lead to uncontrolled failures, reduced availability of the vehicle, etc. and above all represent a security risk.
    In order to ensure the required safety of vehicles (eg rail vehicles, railways, aircraft, etc.) or to prevent failures, regular checks of vehicles, in particular the connections of vehicle components or especially in the chassis, as well as a performance of preventive maintenance work necessary. In particular, the chassis comes on these controls and work due to the high safety requirements on the one hand and on the other hand, compared to an overall train high maintenance costs on the other hand, a special importance. Measures for inspections or maintenance of the vehicle and, in particular, the chassis are, for example, visual inspections, drive checks and / or so-called revisions, which are prescribed and carried out in the context of maintenance plans at fixed intervals.
    In a visual inspection, e.g. an optical and / or visual control of the vehicle or rail vehicle, 201015552 3
    in particular of the landing gear. In this case, for example, mechanical damage, obvious wear, obvious changes in position of components, etc. can be determined. Visual inspections are usually carried out by 5 trained maintenance personnel as human activity and are therefore subject to poor efficiency compared to automated tests. There is thus a risk that errors and / or defects will be overlooked. In the case of drive controls, for example, in addition to the optical-visual test, suitable test methods / systems can also be used to detect defects and / or to rectify faults in the chassis. A revision is a technical review, which is mandatory and in which safety-relevant data of the rail vehicle 15 and the chassis are checked.
    However, often the chassis - which has a special safety-relevant significance - makes it difficult to access safety-relevant bodies and thus limits the possibility of analysis and testing. This means checking and / or checking a vehicle, in particular the safety-relevant points, such as e.g. Connections of components, especially in the area of the chassis, are time-consuming and connected at great expense. Due to the limited ability to analyze, for example in the case of visual and / or drive checks, safety-relevant deficiencies such as, for example, loosened screws or nuts, loose connections between components, which can lead to undesirable relative movements and / or position changes 30, and e.g. so-called emergency interventions, etc. difficult and often not in time recognizable.
    DESCRIPTION OF THE INVENTION The invention is therefore based on the object, a
    Specify a device by which meets increasing safety requirements for a vehicle without great effort and in a cost-effective manner and defects and errors quickly and 201015552 4 • · · * ··· * · ♦ · * · 9 »··» * I · * «· • »II» I * I * * * I »· t I · · ** ·· ♦ II«
    • * * t »» I can be detected in good time, thus increasing the availability of a vehicle.
    According to the invention, the object is achieved by a device of the initially mentioned type, in which an RFID (radio frequency identification) transponder is provided for each component of a vehicle to be monitored or safety-relevant, in particular a rail vehicle, train, etc. is. This RFID transponder, which has a predetermined breaking point, is mounted on components to be monitored in such a way that relative movements and / or changes in position of these components lead to breakage of the RFID transponder at the predetermined breaking point.
    The main aspect of the solution proposed according to the invention is that the RFID transponder with the predetermined breaking point is attached to relevant components to be checked, in particular in the case of connections of two or more components. Upon entry of e.g. unwanted relative movement and / or change in position of a component by, for example, a loose connection, etc. or loss of a component (for example, a nut in a screw connection, etc.), the RFID transponder loses its function. That the RFID transponder at this point of the vehicle or in this component can no longer be detected and a fault / defects in the vehicle can thus quickly and at relatively low cost - even in hard to reach places such. in the area of the landing gear - can be detected and corrected, which reduces the cost of maintaining the vehicle. In addition, the use of RFID transponders makes it possible to detect even very small relative movements between components, and it is also possible to detect human influences such as, for example, to reduce a human error rate for example through emotional-cognitive disposition.
    In the radio frequency identification " (RFID) is usually about identifying with the help of electromagnetic waves. RFID thus enables automatic recognition and / or localization of Objects, etc. and thus facilitates a collection of data considerably. An RFID system therefore usually consists of an RFID transponder, which is located on or in the respective object, etc., and an RFID readout unit for reading out the RFID transponder, in which, inter alia, data for identification are stored.
    Therefore, it is advantageous if, for a functional check of the respective e.g. At least one RFID read-out unit is provided on the vehicle or on the chassis of a vehicle-mounted RFID transponder. This at least one readout unit can either be mounted on the side of the track or on the vehicle for an ongoing functional check. Thus, in a simple and cost-effective manner, the vehicle, such as the vehicle, can be kept running. the chassis of a rail vehicle for defects and defects are examined. If unwanted relative movements and / or position changes occur in monitored components or a monitored component is lost, the RFID transponder breaks at the predetermined breaking point and can thus no longer be detected and read by the RFID readout unit.
    A structure of an RFID transponder provides, in principle, an antenna, a permanent memory or microchip, a carrier and, in the case of so-called active transponders, an energy supply. Data are stored in the memory, which are transmitted to the RFID readout unit and used for identification. If the RFID transponder is broken at the predetermined breaking point, this data can no longer be sent and the defect / fault on the vehicle can be detected in this way. The energy for a communication with the RFID read-out unit can relate to the RFID transponder from the field of the RFID read-out unit, then this transponder is also referred to as a passive transponder. 201015552 • φ Φ • * ι »Φ 6 Φ · *
    However, the RFID transponder can also have its own power supply such. a built-in battery or a connection to an external power supply to increase the communication range of the RFID transponder. 5 RFID transponders with their own power supply are then called active transponders. For the device according to the invention an application of both transponder types {active and passive} is conceivable. A preferred embodiment of the invention provides that each e.g. RFID transponders attached to the vehicle have a unique identifier, e.g. a number, etc., from which a position (e.g., on the vehicle, on the chassis of a vehicle, etc.) of the respective RFID transponder is derivable 15. This identifier is stored for example in the memory of the RFID transponder. In this simple way it can be very easily determined at which position an error / defect such as e.g. an undesired relative movement of a component, a change in position, a loosening of a connection, a loss of a component, etc. has occurred. If e.g. If an RFID transponder with a specific identifier is not detected during a check, then it can be concluded that there is an error at its position. That only in the case of undetectable RFID transponders must - sometimes 25 hard-to-reach places on the vehicle, such as e.g. be inspected more closely in the area of the chassis. This saves costs and time.
    Advantageously, the RFID transponder is fixedly mounted at least on the component of the vehicle to be monitored. In order for a break at the predetermined breaking point at an undesirable relative movement and / or a change in position of the component is facilitated and a lack of the vehicle is thus easier to determine. A fixed attachment of the RFID-35 transponder can be done by fastening means, in particular by gluing, welding and / or screws, since such compounds are easy to install or execute. 201015552 • * 7 * '' '*' «« ··· * · · · · · · · · f * · «« * 4 * »» i »• ·« «· · ·« M · · *
    In particular, it is recommended that chassis components are monitored, which have connections by means of connecting elements. In this way, without much effort and quickly defects such. Loosening of the connections and thus 5 safety-related movements and / or change in position of components are detected. The RFID transponder can be attached to a first component, e.g. be firmly attached and is then connected either with a second component, which has a Vebindung with the first component, or with a jf 10 optionally used connecting means. It is thus also possible to detect relatively small relative movements between the components at an early stage.
    Preferably, components are monitored in which the connection of one or more components by means of a
    Screw connection takes place. In this way, relatively little loosening of screw connections, which occur, for example, as a result of vibrations during use of the vehicle (for example rail vehicle) or the landing gear, can already be ascertained without great expenditure of time. With the device according to the invention, e.g. loosened and missing screws and / or nuts are detected, which in a visual inspection. due to their position (for example difficult to access) or because of the slight loosening 25 are hardly recognizable.
    Brief description of the drawing
    The invention will now be described by way of example with reference to Figure 30 of the accompanying figure. 1 shows, by way of example and schematically, the device according to the invention for automatically detecting relative movements and changes in position in a vehicle on the basis of an exemplary component connection in the region of a chassis of the vehicle. 35 8 201015552 # · «· ·« «• · · · ·
    Embodiment of the invention
    FIG. 1 shows, by way of example and in a schematic manner, a first component 1 and a second component 2 of a vehicle, in particular a railway chassis or a chassis of a rail vehicle. The first component 1 is connected to the second component 2 by means of a third component 3 (for example a screw 3). In addition to a connecting means or a screw 3 and a shim, this exemplary screw connection also comprises a screw nut 4 for better fixing of this connection.
    In order to be able to detect undesired relative movements between the first component 1 and the second component 2 or to detect changes in the position of the first component 1 and / or a loosening of the screw connection or the screw 3, an RFID transponder 5 is located on the first component 1 appropriate. The RFID transponder 5 has a predetermined breaking point 6, by which the RFID transponder 5 is divided into a first part 7 and a second part 8. The first part 7 of the RFID transponder 5 is fastened on the first component by means of fastening means 11. As fastening means 11, for example, screws, adhesive, a welded joint, etc. can be used.
    The second part of the RFID transponder 5 is in communication with the screw connection or with the nut 4. It is also conceivable for other component connections in vehicles that the second part of the RFID transponder 5 is mounted, for example, on the second component 2, on the screw 3, etc., in order to prevent any relative movements and / or position changes, loosening of the screw 3, etc. to recognize.
    Furthermore, the RFID transponder comprises at least one shock protector / carrier, an antenna 9 for a data transmission to an RFID readout unit, which, in order to simplify FIG. 1, is not shown, and a memory element or a microchip 10, in FIG which data for the identification 9 9 • · 201015552 of the RFID transponder 5 are stored. The antenna 9 of the RFID transponder 5 is arranged in the carrier material such that it is guided over the predetermined breaking point 6 and thus extends from the first part 7 of the RFID transponder into the second part 8. Therefore, the antenna 9 is destroyed at a breakage of the RFID transponder 5 at the predetermined breaking point 6. The RFID transponder 5 thus loses its function and can no longer be detected by the RFID readout unit.
    If, for example, the load on the exemplary chassis, vehicle, etc., the nut 4 loosened or loosened and thus unwanted relative movements between the first component 1 and second component 2 or changes in position of the first component 1 or the screw 3 is possible, so breaks the RFID transponder 5 due to this relative movement or change in position at the predetermined breaking point 6. Due to the course of the antenna 9, the antenna 9 is destroyed when breaking the RFID transponder 5 and the RFID transponder 5 can no longer be detected or read by the RFID readout unit.
    Due to the missing data of the RFID transponder 5, the lack of the vehicle or chassis - e.g. a loosened Schaub connection, loose screw 3, etc.-recognized. Since the RFID transponders 5 mounted on the vehicle have an identifier from which a position on the vehicle can be clearly deduced, the position of the defect can be easily determined on the basis of a missing feedback of a broken RFID transponder 5.
    It can then be targeted, a repair to be performed on this position of the vehicle and possibly the broken RFID transponder 5 are replaced by a new, so that a recent lack of this position is easily detected. 201015552 v * 10 f · · · * ·, · «« ··· j «« «« ««
    The readout unit for checking the function of the RFID transponder 5 can be used, for example, in the maintenance or servicing of vehicles. However, it is also possible, for ongoing monitoring or monitoring of the vehicles, in particular in the area of rail vehicles and / or railways, to install on the trackside RFID reading units, which then transmit the RFID transponders 5 to passing vehicles or e.g. read out their landing gear. If one or more RFID transponders 5 are no longer detected, e.g. quickly a check, etc. of the respective vehicle be prompted. 11 201015552
