Definitions
- the invention relates to a method for condition-based maintenance of a clutch arrangement for track-guided vehicles, in particular rail vehicles, and also to a monitoring system.
- guided vehicle includes, but is not limited to, trains, wagons and railcars that run or are guided on one or more rails. These are in particular fuel-powered or electric trains or trams.
- the term “coupling arrangement” is primarily to be understood as meaning at least that part of a coupling system of track-guided vehicles which enables the mechanical connection between the two vehicles.
- the coupling arrangement makes it possible to absorb and pass on both impact and tensile forces. These are mounted or designed on the rail vehicles in such a way that they can be displaced and pivoted in a curve or incline in order to maintain their alignment and thus the mechanical coupling in a stable manner.
- the coupling arrangement includes in particular a coupling head with coupling elements for coupling to a coupling head of a counter-coupling, furthermore, depending on the design, a coupling rod, a linkage or bearing and optionally energy-absorbing elements.
- the term coupling arrangement includes here in particular all elements from the interface to the car body to the interface for coupling to the counter-coupling.
- the coupling arrangements and their individual components are usually designed for a specific application in order to be mechanically stable and reliably coupled to one another in the most varied of situations; regardless of rail vehicle type and/or straight or curved track sections on horizontal plane or with incline. Further, the interpretation is made to predefined To be able to transmit tensile forces over a predefined operating period and to compensate for impact forces of a predefined size. For this purpose, it is provided in such clutch arrangements that a damping device absorbs tensile and impact forces up to a defined magnitude and transmits forces in excess of this to the vehicle underframe.
- the damping device is not able to fundamentally prevent tensile and impact forces from being introduced into the components of the clutch arrangement. As a result, the components of the clutch assembly are exposed to more or less permanent wear during operation.
- the clutch arrangements are also exposed to a wide range of other conditions which can have a not inconsiderable influence on the theoretically intended service life of the individual components of the clutch arrangement.
- the wear of the clutch arrangement during the coupling process can increase if the self-centering of the clutch arrangements to be coupled to one another is made more difficult if the clutches are farther apart or offset from one another.
- intervals are predefined in such a way that a failure of individual components due to wear is avoided under normal conditions with certainty before the maintenance time is reached.
- a predefined period of time is usually specified or the maintenance request is made defined over a distance covered by the rail vehicle that describes the operating time.
- the information on the operating mode and condition of the clutch arrangement obtained from the clutch arrangements associated monitoring systems can be used to support inspection and maintenance.
- a monitoring system is described in DE 102013 206977 A1, for example.
- US 2018/0162423 A1 provides a monitoring system that detects the structural changes directly on the coupling itself, in particular on the coupling rod.
- DE 10 2019 106 961 A1 describes the arrangement of
- condition monitoring system for train couplings which detects both external and internal structural damage, including damage to the part hidden under the car body, even when the train is in operation.
- the condition monitoring system includes one or more sensors mounted on or integrated into the coupler assembly, a data acquisition unit for receiving signals or data from the sensors, and a processing unit for determining the structural condition of the train coupler based on the received signal or data. Controls over the system can be continuously real-time or carried out periodically during the operation of a train. It can also be done offline while a train is not running.
- Detection devices require additional modifications to the individual components, in particular the clutch arrangement, and ensuring the functional reliability of the detection devices and monitoring systems is complex and costly.
- DE 102015205978 A1 describes a system for documenting the state of a motor vehicle by means of image and data acquisition with time assignment by setting a time stamp.
- the invention is therefore based on the object of specifying a method for servicing clutch arrangements which, with the least possible additional design effort on the clutch arrangement itself, enables relatively reliable statements to be made regarding required servicing/maintenance, with unnecessary downtimes being to be avoided. It must be ensured that the individual components of the clutch arrangement - even after a long period of operation - function properly and are integrated accordingly into the overall clutch concept of the vehicle, without the individual components of the clutch arrangement being individually and regularly connected to a classic
- the method according to the invention for condition-based maintenance of a coupling arrangement of a rail-guided vehicle, the coupling arrangement having at least one coupling head for coupling to a coupling head of the opposite type of a counter-coupling and optionally at least one line coupling for coupling to a line coupling of a counter-coupling for transmitting electrical charge and/or data and/or liquid or gaseous media comprises the following method steps: a) providing clutch arrangement data in the form of operating data and optionally status data of the clutch arrangement; b) providing environmental data to describe information about the environmental conditions to which the clutch arrangement is exposed; c) Transmitting the provided data to a data processing system and determining a target specification for a maintenance request for the clutch arrangement as a function of the provided clutch arrangement data and environment data; d) recording of images of the clutch arrangement for optical reproduction of the actual state and transmission to the data processing system; e) Evaluation of the optical actual state of the clutch arrangement from the images, taking into account the target specification for the maintenance request formed from the operating and state data
- “Clutch arrangement data” within the meaning of the invention is understood to mean, in particular, data which is suitable, at least indirectly, for describing the mode of operation of the clutch arrangement and its individual components and/or the environmental conditions. These include operating data, environmental data and optionally but not necessarily status data.
- Operating data is in particular data that describes the functioning of the clutch arrangement. In particular, this includes: Number of coupling processes in a definable period of time; state - coupled/uncoupled; coupling speed; dome shocks; operating time (period, km driven); GPS data.
- “Status data” is in particular data that describes the physical or chemical properties of the clutch assembly and its components. “Environmental data” within the meaning of the invention is understood to mean data that contains information about the environment, which is present in particular as chemical or physical variables that can have an impact on the aging and wear of the components of the clutch arrangement. These include physical and chemical variables such as temperature, humidity, type, intensity and nature of precipitation, etc.
- a "target specification of a maintenance request” is understood in particular as information relating to and describing the next required maintenance and/or the next replacement of a component.
- the solution according to the invention offers the advantage, on the one hand, of providing a purely data-based specification for a maintenance request for the clutch arrangement and of being able to verify this by means of an additional visual inspection and, if necessary, to be able to flexibly adapt it.
- the consideration of the data characterizing the mode of operation of the clutch arrangement and the environmental data containing information about environmental influences, which can affect the service life, allows very precise target specifications that are closely based on the actual loads to which the clutch arrangement is exposed. This avoids unnecessary downtimes, which are caused on the one hand by an early breakdown or failure of individual components or on the other hand by carrying out an inspection and maintenance that is not yet necessary in relation to the condition.
- the solution according to the invention thus enables the service intervals to be optimally adapted to the actual state of the clutch arrangement.
- the target specification for the maintenance requirement preferably includes a variable that at least indirectly characterizes the theoretically possible, preferably a maximum permissible, remaining operating time of the clutch arrangement until the next maintenance as a function of the detected clutch arrangement data and environment data. This remaining service life describes the interval in which the clutch arrangement is still "properly functional".
- the theoretically possible remaining operating time can be a) a time specification, in particular a1) a period of time in the form of a still permissible remaining operating time until the next required maintenance or a2) a date specification or a limited period of time or b) a length specification, in particular an indication of still to driving km until the next required maintenance or c) a combination of both are described.
- variant a) also includes downtimes, in which the clutch arrangement can also be exposed to extreme weather conditions
- variant b) includes the actual operating period in which the clutch arrangement is exposed to the loads.
- Variant c) in particular allows the next required maintenance to be determined very precisely in advance and makes it possible to plan it well, in particular with regard to the area of use of the rail vehicle carrying the coupling arrangement.
- the provided clutch arrangement data, the environmental data and the data containing the images are provided with a time stamp and stored together with this.
- the changes in the data over time become transparent and the change behavior of these over a defined period of time can also be taken into account and conclusions can be drawn from these for the remaining service life.
- the clutch arrangement data and the environment data during operation of the vehicle carrying or having the clutch arrangement are at least partially, preferably completely, on the vehicle side, in particular by means of a data assigned to the vehicle anyway for other tasks
- Data provision device recorded Preferably, the data already recorded or present in the control of the vehicle itself are used.
- This design offers the advantage of being able to access and use data that is already available and required for control and/or regulation tasks of the vehicle.
- the additional detection and thus the provision of corresponding detection devices on the clutch itself can be reduced or even completely avoided.
- the expense with regard to additional devices to be provided for the acquisition of specific data can be minimized or avoided altogether.
- the clutch arrangement data and the environment data are recorded at least partially, preferably completely, during the operation of the vehicle carrying the clutch arrangement with a data preparation device assigned to the clutch arrangement. This allows detection independent of the vehicle.
- at least the following clutch arrangement data and environmental data for the individual clutch arrangement are recorded and made available for deriving a target specification of a maintenance request: running time of the vehicle carrying the clutch arrangement, in particular
- additional operating and status data can also be recorded, which allow the target specification for the maintenance request to be specified even more precisely.
- the optical images are recorded only upon request at a request time or at predefined time intervals and then evaluated at an evaluation time.
- the provision of the clutch arrangement data and the determination of the setpoint specification for the maintenance request according to method steps a) to c) take place at least at the time of the request or in the predefined intervals for recording the images.
- the clutch arrangement data can also be recorded continuously and method steps a) to c) can be repeated cyclically or iteratively.
- the images recorded on request can be assigned to the clutch data available at that point in time and the information obtained from them and subjected to an evaluation. Due to the cyclical or continuous provision of clutch arrangement data and environmental data and the resulting adjustment of the target specification, short-term and extreme changes in the mode of operation can be taken into account promptly when determining the next maintenance time or period.
- all method steps according to claim 1 are repeated cyclically or iteratively.
- devices corresponding to the device are provided on the coupling arrangement for recording the images.
- This can in particular be detection devices integrated on or in the clutch arrangement, in particular image sensors.
- the optical actual state of the clutch arrangement is evaluated by comparing the actual state with a target state. Will If no deviations of the actual state from the target state are determined, the target specification for the maintenance request from the clutch arrangement data is retained or even extended from the target specification depending on the remaining operating time that is still available.
- a change in the target specification for a maintenance request is determined depending on the type, scope and direct or indirect influence of the deviation on the functioning and the remaining operating time determined by the target specification until the next maintenance of the clutch arrangement and/or individual components and set as the new target specification.
- the deviations are classified into different classes for evaluation as a function of their direct or indirect effect on the functioning and/or remaining service life of the clutch arrangement.
- At least one specification for changing/correcting the target specification for the maintenance request is assigned to each class, with the change/correction of the target specification as a function of the deviation having the greatest effect on the functionality and/or remaining service life of the
- Maintenance request result in a specified remaining service life.
- the former do not cause any correction of the target specification.
- the latter can be further analyzed with regard to the extent and a theoretical point in time of the occurrence of an impairment of the functioning of the clutch arrangement, the target specification of the maintenance requirement from the operating and environmental data is then corrected accordingly.
- damage to components/components which can lead to a later failure of these and thus to failure and impairment of the entire clutch arrangement, can be detected early and replaced or overhauled in good time by correcting the maintenance specification.
- the clutch arrangement data and/or environment data and/or images are preferably stored in a database, which can be part of the provision devices or an edge device or a cloud structure.
- the determination of the target specification for the maintenance request and/or the evaluation of the optical actual state of the clutch arrangement from the images, taking into account the target specification for the maintenance request formed from the operating and status data at an evaluation time, is preferably carried out decentrally by edge processing or cloud computing.
- the data is transmitted wirelessly, with no restrictions in terms of the type of transmission and technology. Depending on the arrangement of the memory, this can be done via WLAN, radio, Bluetooth, etc., for example.
- the target specification and/or the correction specification for the target specification are determined with the aid of at least one mathematical model.
- the mathematical model can be created with the help of methods of artificial intelligence, such as machine learning or a neural network.
- Alternative methods use decision trees, methods of linear or non-linear regression, etc. This allows high-quality, high-precision and reproducible specifications for the service intervals.
