Also The present invention provides a control device for performing or Driving steps of an embodiment of the above Method is formed.

Under a control unit can be understood in the present case an electrical device, the sensor signals processed and dependent of which outputs control signals. The control unit can have an interface, the hardware and / or software formed can be. For a hardware training can the interfaces, for example, part of a so-called system ASICs be, which includes a variety of functions of the controller. It but it is also possible that the interfaces are own integrated circuits or at least partially consist of discrete components. At a software training can the interfaces may be software modules, for example, on one Microcontroller in addition to other software modules are available.

From Advantage is also a computer program product with program code, the on a machine-readable carrier as a semiconductor memory, a hard disk storage or a optical memory is stored and to carry out the Method according to one of the embodiments described above is used when running the program on a controller.

The The present invention is based on the recognition that as the Knowledge also a connection between the operating parameters and information about the wear of the Component of the machine or the information about the quality of a improved by the machine to be produced product. For example, in a laboratory of the manufacturer of the machine in subsequent investigations be determined that certain additional operating parameters of the machine also relevant information about the wear of the Component of the machine or the quality of the product to be manufactured enable. The Machine can be a machine tool such as a milling Machine for milling a workpiece in x-, y-, and / or z-direction, a drill a lathe, to be a laser cutting machine. Also, the machine can be a wind turbine or a hydraulic power unit or any other machine. Under operating parameters can Signals are understood that represent physical quantities. For example, operating parameters Vibrations of components of the machine represent or revolutions of Motors, currents and / or voltages.

After this however, the algorithm for providing this information over the Wear of the component the machine or the information about the quality of the product to be produced Product is already stored in a memory of the machine there is a problem in this context recognized at a later time between operating parameters and the wear of the components of the machine or the quality of the product to be able to. The approach proposed here allowed consideration such further information in that, for example created by the manufacturer of the machine a new algorithm can be a new relationship between the operating parameters and the wear of the Component or quality of the product to be produced. It can the Manufacturer (or a central operator of several machines) different sentences obtained from operating parameters, for example, from multiple machines and through a simulation (for example with the simulation tool MATLAB) the effect of these operating parameters on the component of the machine or the quality of the product. In this simulation, recent findings about disturbances with considered For example, since the creation of the algorithm in the Memory in the machine have become known. On the basis of this new knowledge (for example, by the simulation tool itself) a new algorithm, namely a Created a replacement algorithm in which these new known disturbances or, generally speaking, the new relationship between the operating parameters and the wear of the Component of the machine or the quality of a finished product to produce are implemented. This replacement algorithm is then over a Transfer interface back to the machine or a plurality of machines and replaces the previously stored algorithm.

The The present invention thus offers the advantage that a connection between operating parameters and wear of a component of the machine or a quality a product to be produced by the machine always up to date Knowledge can be maintained. This allows a timely Replacement of a component, such as a bearing or a shaft the machine, allowing downtime by using of knowledge that was obtained only after delivery of the machine, let reduce even further. This can also be done after delivery of the Machine obtained knowledge to ensure a high quality of the product be used, which is manufactured by the appropriate machine.

Cheap is it if the algorithm provided in the step of providing the information about the wear of the Component of the machine or information about a quality of a through the machine to be manufactured using a first Set of operating parameters allows and where the in step the receiving replacement algorithm receives the information about the Wear the Component of the machine or information about a quality of a through the product to be manufactured using a second Set of operating parameters, with the first and second set of operating parameters. Such embodiment The present invention offers the advantage that further operating parameters, that in providing the information according to the algorithm to be replaced not considered yet were now also considered. This allows a Improvement of the assessment of the wear of a machine component or the quality of a product to be manufactured.

Also can in another embodiment according to the invention, the step of obtaining are carried out in such a way that the plurality of operating parameters of a plurality of stored or currently recorded operating parameters of the machine selected become. Such an embodiment The present invention offers the advantage that the replacement algorithm has significantly more operating parameters available and thus, for example via a statistical evaluation, a relationship between individual operating parameters and the wear of the Component or quality of the product can be determined. So you should not be alone anymore those operating parameters that are available for the replacing algorithm were relevant, but significantly more operating parameters be provided, from which the replacement algorithm the corresponding Can determine information.

Also In the step of receiving the replacement algorithm, a replacement algorithm may be used received, which is designed to be received as operating parameters Extract and store characteristic data, the characteristic data allow a classification of an event that can occur when the machine is in operation. Such an embodiment The present invention offers the advantage that a reduction that took into account Operating parameters allows for specific characteristics, which is a lighter Allow classification of an event. These characteristics can then stored in the machine and of other functions be used.

Also may in the step of receiving the replacement algorithm and replacing of the algorithm in the memory, changing a data storage structure for one Storage of operating parameters of the machine and / or changing an output of results of the replacement algorithm on a display device for one Operator. This offers the advantage of being one to the replacement algorithm adapted storage of operating parameters or one to the replacement algorithm adapted output of results of the replacement algorithm is enabled. In this way, a fast and efficient processing of the operating parameters respectively.

Further can in the step of evaluating the replacement algorithm in the form a dynamic library or created in a machine code become. Such an embodiment The present invention offers the advantage that the replacement algorithm immediately executed on the machine can be and no special software tool to execute this Replacement algorithm must be loaded.

Cheap is it also, if in the step of evaluating knowledge of a context the received operating parameters with the wear of a Component of the machine or knowledge of a context of the received operating parameters with a quality of a produced by the machine Be used in a preparation of the replacement Algorithm not available were. Such knowledge, which in the creation of the to be replaced Algorithm not yet available were a further development of the available knowledge, so that thereby an improved detection of wear of the one Component of the machine or a quality of the machine to be manufactured Product possible becomes.

In a further embodiment of the invention, in the step of receiving operating parameters can be received from machines that over period of at least one month, in particular over a period of at least half a year. Such an embodiment of the present invention has the advantage that the evaluation of the operating parameters over a longer period of time can take place, so that even weak wear tendencies or a continuous decrease in the quality of a product in the creation of the replacement algorithm can be adequately considered.

Further can also in the step of evaluating operating parameters of machines are evaluated, which are designed for the production of different product types are. Such an embodiment The present invention offers the advantage that in machines, which are designed for the production of different product types are, same elements can be used. These elements have often the same texture, so that by the different Strain in different engines conclusions the load capacity these components are possible. this makes possible a better estimate the long-term wear behavior the respective components in the individual machines.

The The present invention will be described by way of example with the aid of the following mentioned figures closer explained. Showing:

1 a block diagram of a system architecture with an exemplary control device for a machine, can be performed on the embodiments of the present invention;

2 a block diagram of an embodiment of an action recorder;

3 a block diagram of a system for data delivery;

4 a flow chart of a first embodiment of the present invention as a method; and

5 a flowchart of a second embodiment of the present invention as a method.

Same or similar Elements can provided in the following figures by the same or similar reference numerals be, with a repeated description of these elements is omitted.

1 shows a block diagram of a system architecture with an exemplary data processing unit (Remote Condition Monitoring System) 10 for a machine on which embodiments of the present invention can be carried out. The machine includes components 20 which may include, for example, a bearing, a drive motor, sensors, controls and / or other components. Controls (NC, PLC, Motion, RC, ...), actuators (drive, possibly also with integrated PLC or motion) and intelligent sensor systems (possibly also with own evaluation unit) can be found on the real-time level. The units 30 can via an interface 40 with a functional interface 50 to encapsulate the actual functionality, in the operating parameters (for example, vibrations, control signals or other detectable physical variable such as the sizes mentioned above) this function interface 50 over the interface 40 be supplied. The functional interface 50 as well as the unit from a third party 33 can also be from a machine tool 35 be supplied with measurement data. The functional interface 50 has an interface 60 to a database 70 in which setup data, characteristics, graphic data, raw data or other data can be stored. Database 70 may be, for example, an SQL database (for example, from Microsoft or Oracle), which contains, among many other data for each method setup data, characteristic data, graphics data, raw data and the like. Furthermore, the function interface includes 50 an algorithm execution unit 80 in the example of the algorithm or the replacement algorithm on individual, a group of several or all over the interface 40 received operating parameters is executed. The algorithm execution unit 80 can also be designed as an interface for integrating dlls (for example with the simulation tool Mathlab), ie for integrating algorithms that were created and tested with Matlab and then transferred to C # code. The data output by the executed algorithm can then be sent via the interface 60 transferred and in the database 70 be stored. The control unit 10 can be used as a generic data server 85 be designed that the interface 40 that functional interface 50 , the interface 60 , database 80 as well as the algorithm execution unit 80 includes. Furthermore, the function interface 50 an interface 90 to further data processing units or computers that, for example, a web server 100 (For example, be implemented in Microsoft ASP .net technology and other graphics components) and a Web client 110 (which may be executed, for example, as an AJAX (ie Java Script) in the browser) which may be designed according to the Microsoft .NET standard.

In accordance with an embodiment of the present invention, a definition file may now be provided 120 for the database 70 be provided Among other things, a change in a visualization, an evaluation and a measurement data structure in the control unit will be achieved and as a replacement algorithm in the algorithm execution unit 80 is loaded. Specifically: The measurement data file is used to describe the surface characteristics (type of display, color selection, specification of the values to be displayed), to describe the tables required for the evaluation method within the database and to describe the structure of the measured data file, with the help of the measured data from the Real-time part to be transmitted to the remote condition monitoring system. (The description of the measured data file structure allows easy parsing and interpreting of the data supplied in the measurement files.) For example, within the file for a circularity test, besides the actual measurement data, such as setpoint and actual position of the motor and the external encoder, or the actual and target speeds, other parameters provided, such as the sampling time with which the recording was made in the real-time part, or the circle diameter, the speed traveled, etc.). This definition file 120 for example, using a measurement data file 130 obtained by measuring operating parameters (with header signaling information) of one or more machines 35 is sent to a specially designated location (the Remote Condition Monitoring System). This definition file 120 can do this in the algorithm execution unit 80 be loaded and a change in data processing and storage of processed data in the database 70 or a change in the output of the changed data via the web server 100 or the web client 110 cause.

In this case, a communication can be made possible in such a way that an OPC-UA (OPC-UA = OPC-Unified Architecture = OPC Original: OLE for Process Control) is planned between the devices and the GDS (GDS = generic database server 85 ) For now, one of the devices 30 proven SCP interface 40 be used. Between the GDS 85 and the web server 100 or the MES systems, an OPC UA can be used, for example, in the first step, SQL function access through the function interface 50 be encapsulated. The communication between the web server 100 and the web client 110 can be done for example via the protocol HTTPS. Also distributed systems can be used, such as a web server with multiple GDSen (via a communication via UA) or a central GDS (for example, Oracle-DB) is fed by several smaller decentralized GDSen.

One in the device 10 integrated configuration means for configuring the data analysis unit (or algorithm execution unit 80 ) regarding the analysis to be performed and the configuration of the device 10 With regard to the manner of further processing of the result of the data analysis by means of one of the interfaces or by means of the long-term data memory can be provided.

The configuration means, for example, the definition file 120 into the algorithm execution unit 80 or in the database 70 loads, makes it possible to integrate new methods / algorithms, for example in the form of # C-dlls (dll = dynamic link libraries eg generated with the programming language C #), whereby the interfaces between the system and the data analysis unit 80 can be defined in more detail by means of XML files in order to be able to quickly integrate, for example, any evaluation methods (methods) in a simple manner. Using the XML file (for example, in the definition file 120 ), the characteristics of the surface, the graphics, the characteristics, their graphic characteristics and the structure of the measured data are described favorably. In this way, any evaluation methods, such as a circularity test, in a simple manner in the system 10 to get integrated. In this solution, the simulation tool Matlab is preferably used (for example for simulation and for creating a dll).

In other words, that works in 1 described system as follows:

First:

From time to time (eg every two weeks), or after critical events and crashes systematically started certain test methods to check the machine condition. Here, on the NC, PLC, RC, MC, intelligent drive, intelligent sensor system certain suggestions performed, certain data recorded and forwarded to the RCM system. There, the generated measurement data files are read in and on defined conditions (in the definition file 120 described) tested. Here, the data quality is checked and stored in the form of a key figure in the DB with the relevant measurement. Afterwards, the actual evaluation of the data will take place. The respective algorithms then determine specific parameters for each measurement, which in turn are stored within the database. For example, for a circle, this is the circularity deviation. For each test method, several graphics as well as several parameters can be calculated and then displayed. Interesting for the user is in particular the long-term trend. Does this change in an inadmissible way, z. B. an exponential increase, Thus, the components in question can be examined in more detail with other methods.

Secondly:

With Help the GDS can cyclic or only on change any variables (states, such as the motor current or the Temperature of a drive) and the temporal Behavior in the form of a diagram to be analyzed in more detail.

2 shows a block diagram of the integration of an action recorder. This is a real-time system 200 (which is executed, for example, in a machine such as a milling machine, a drilling machine or another of the machine tool) and a data processing system 210 which, for example, may be a PC that can not perform real-time data processing. On the real-time system 200 For example, functions may be used to control the operation of the machine, such as an NC program 215 or a PLC program 220 , These functions for controlling the operation of the machine are stored in an action recorder MTX acr (essentially used to record events of all kinds (this may be inputs of the user, or specifications of other external systems) 225 , for example, an NC server 230 , a sentence preparation 235 or an interpolar 240 processed. The results (only those selected by the machine manufacturer [configured]) for block preparation 235 or the interpolator 240 can in a ring buffer 250 be stored. Events, special events, critical events or accidents (crashes) 255 By controlling the MTX acr 225 recorded in a logbook memory 260 stored. The data is generated on the one hand by the firmware of the controller at specific points (user can configure this). However, events from the NC program can also be used 215 and the PLC program 220 generated and transferred to the logbook memory. This log store 260 can have a very large data storage capacity and thus the events or accidents (crashes) that occur over a very long period of time 255 save. Additionally, in this logbook memory 260 additional data 265 (For example, target and actual positions in different coordinate systems) from the ring buffer 250 (for example, in a crash) are stored. The logbook store 260 is conveniently in the data processing system 210 (For example, a PC) arranged that no real-time data processing must be able to perform. Furthermore, in the non-real-time data processing system 210 one unity 270 are provided for performing a function for visualization and configuration, the configuration data 275 parameterizes the recording functions within the control firmware. For example, it determines whether changes to the tool data entered via the user interface are written to the logbook or not. Furthermore, the configuration data 275 also a user 280 are displayed.

From the logbook memory 260 the non-real-time data processing unit 210 can transfer data to a generic data server 85 be sent, for example, a in 1 illustrated interface 90 to a web server 100 and continue to a web client 110 connected. About the web client 110 the obtained results can be displayed graphically or visually.

The logbook store 260 can do this through the database server 85 be read so that certain events can be detected and in response to these events service personnel is sent to service the machine on which the real-time system 200 running. For example, an accident of a tool of the machine tool can be detected on the real-time system 200 running. In this case, corresponding events or accidents 255 the logbook memory 260 which can recognize the accident of the machine / tool from the transmitted data and via the generic database server 85 can send a service technician to the machine on which the real-time systems 200 running. In this way, the maintenance of the machine, which is the real-time system, is significantly improved 200 includes. In the case of crashes or other critical events, further test methods can be specifically carried out. With the help of these further test methods, the individual components can then be examined more precisely with respect to their condition.

In other words, that works in 2 described system as follows:
The Action Recorder MTX acr collects all relevant events, from simple status information to crashes. This information can then be used in the higher-level remote condition system to assess the machine condition or quality of the machine.

As machine events, user-specific inputs or messages can be considered as events, for example. As a special. Events may include errors or BA switching. A critical event could be, for example, the jamming of a tool clamping system. A crash can then be detected if the tool is controlled uncontrollably in the workpiece or a bracket. As a basic functionality of the real-time system was considered to be that the Action Recorder gets told via SD data, what he should record. For the crash case, for example, there is a ring buffer for each configured axis (the storage period can include a position setpoint and actual value for approx. The last 10 s and approx. Every 100 ms). By means of a PLC-FB (PLC-FB = PLC: Programmable Logic Controller; FB Function Block = One Piece PLC-Program), the PLC can set any event in the logbook memory 260 write. The PLC-FB offers several functionalities, for example it can provide NC-data with the logbook 260 to write. It can also attach an additional file or allow a language-independent implementation if required by means of IDs. In the same way, events can be written to the logbook on the NC by the NC program. The data management can be done on the PC part. A visualization can be done in a container, for example, to list the events in chronological order. If a GDS is present, for example, the data is cyclically loaded by the GDS (for example by means of a file transfer). Also, the data can be processed and in the DB 70 be filed. Statistical evaluations with corresponding graphics can be planned, eg For example, to determine how long the machine is standing still for certain reasons.

The advantage of this solution is also that by means of the long-term data memory 260 the changes of operating parameters to the administration system 210 connected automation components can be logged over a longer period. For long-term recordings according to the invention, buffers can be provided for data volumes of up to 10 terabytes. By means of the data analysis unit (for example in the unit 70 for performing a function of the configuration or visualization, the data processing unit 210 or in the generic database server 85 ) it is possible during or after the data buffering (even after years) to examine the data logged by means of the interface with arbitrary methods / algorithms (possibly several times in succession) in order to derive insights regarding the state of the automation system component. The results generated by the data analysis means can then be stored in the long-term memory or cached, as well as by means of one of the interfaces to a connected system 85 . 100 . 110 forwarded after being prepared according to the data protocol to be used. In addition, a manufacturing management system, which usually takes over the data update, be relieved of the required computing power. The middle 225 thus serves as an interface for exchanging data between two systems which can use different communication protocols. The middle 225 (ie the MTX action recorder, which is integrated in the real-time part of the MTX as part of the firmware) also has the function of a control entity, which connected to the device components, such as programmable logic controllers (PLC), numerical controls (NC, CNC), controllers and Engines, monitored with regard to their operating status, their operating status analyzed and the higher-level system 210 . 85 communicates this operating state.

In addition, operating parameters of an automation system component connected to the device can be changed during operation and thus corrected during runtime by means of the second interface. The long-term data memory 260 could also be used as a data buffer for the data analysis unit 210 serve, with the analysis results or intermediate analysis results in the long-term data memory 260 stored and by means of the data analysis unit 270 can be read again from the long-term data storage and processed further. The data from the long-term data memory 260 can by means of a connectable to the first interface superordinate system of this parent system 85 be retrieved. It would also be conceivable to make the data storage retrievable by an automation system component connected to the second interface.

3 shows a block diagram of a system for data delivery. Here comes the real-time part of the MTX acr (the MTX acr core service) ( 310 ) whose main task is to record events within the CNC control core MTX 320 used (part of the control firmware) The MTX acr core service 310 has an interface to the mount directory 325 and another interface to a SCP 330 , On a human machine interface PC 335 running an MTX acr panel service 340 the data from the mount directory 325 and the SCP 330 receives. The MTX acr panel service 340 returns data to an archive directories 345 and data about an XML directory 350 , From the XML directory 350 Data becomes a visualization function 355 and data about a database 70 a generic database server 80 sent (Remote Condition Monitoring System) to the data from the database 70 also to a visualization functionality 360 to be used. The generic database server 85 offers a functionality of remote control monitoring 365 ,

In other words, that works in 3 described system as follows:
The user-configurable MTX acr core service displays all configured events with an exact time stamp and stores them in the logbook. Furthermore, data can also be written to the logbook from the PLC as well as from the NC. The data is then stored on the mount and processed further from there by the MTX acr panel service. Here, the data are sorted in their time sequence from the various subsystems (NC server, PLC program, NC program, ...) and enriched with texts. Furthermore, at this point a graphical distribution (Style) is optionally available for later display within the user interface or in the RCM system.

By means of the device according to the invention, for example according to the 2 or 3 a machine-oriented long-term recording of process status data and machine status data is possible. Due to the realizable long-term recording, data can be made available for the exact analysis of the cause of problems on machines for optimizing products (eg components of a machine tool) and for optimizing process sequences. Certain changes of parameters in the test methods can be related to the events and further future actions derived therefrom. In the simplest case z. For example, to prevent incorrect operation of the machine or during programming, which lead to a crash.

It can additionally a preprocessing unit for Data includes. The term preprocessing unit was chosen because by means of preprocessing the optimization of communication between GDS and MES (MES = Manufacturing Execution System) and thus one Relief of the MES can be achieved. The actual processing of Data in the sense of a control center or process control takes place however, for example, with the MES.

The Configuration of a processing operation can take the following steps include:

a) Definition of the processing time: (Start of test methods)

• – bei wiederkehrenden Ereignissen;
• – bei Anforderung durch den Nutzer;
• – bei Start durch ein übergeordnetes System;
• – wenn ein Messpunkt einen bestimmten Wert annimmt (z. B. Wechsel der Betriebsart);
• – wenn der Speicher (beispielsweise der Logbuch-Speicher 260) bis zu einer bestimmten Größe belegt ist (z. B. Speicher zu 90% mit Daten gefüllt).

First, a start event is defined. The processing can be started cyclically at specific time intervals or at defined times depending on this start event. In addition, it can be defined under which circumstances the processing should be started, e.g. B .:

• - for recurring events;
• - when requested by the user;
• - at start by a higher level system;
• - if a measuring point assumes a certain value (eg change of operating mode);
• - if the memory (for example, the log memory 260 ) is occupied to a certain size (eg 90% memory filled with data).

b) Definition of the data structure for the processed Metric:

Here, measurement data can be grouped. It can be specified where in the GDS 85 Evaluation results are to be stored (database, file system) and whether, or to which addressee, a notification regarding existing calculation results should be sent. It is also possible to define the memory size (eg n data bytes in a ring buffer). Furthermore, it can be defined whether a reference to the data base used for the calculation should be stored together with the prepared data. For example, it can be referred to where the input data for the calculation came from and how they are to be assigned to the result. There is also information on how many input values were used for the calculation, the period from which these input values originate and whether they are still stored in the data memory or already deleted. In addition, it can be defined whether and how the data structure for the prepared measured values is integrated in the measurement point browser.

c) Definition of processing: (the end user has nothing to do with it, runs automatically off; the following things will be discussed in advance RCM surface configured; corresponding users (with appropriate authorization) can but reconfigure this at any time)

In A third step may be the way of data processing be defined, for example by selecting an appropriate Algorithm, for example, to calculate an average, too Calculation of minimum or maximum values or to perform a Fourier transform. Certain inputs and / or outputs of a The automation system components connected to the GDS can be targeted linked to an algorithm so that different algorithms for different operating parameters of the Automation component are used. Also it is possible in the Frame the processing to validate the correct interconnection, for example the data type and the amount of data, such as the minimum number of input values.

In this way, a device-integrated configuration means for configuring the data analysis unit is performed analysis and for configuring the device with regard to the manner of further processing the result of the data analysis by means of one of the interfaces or by means of the long-term data memory.

In summary, it can be said that demands for ever better and reliable evaluation methods have given rise to the approach presented here. These requirements can be met by a generic integration of methods that allows component-based detection of crashes (ie accidents) and critical events as well as consideration of manufacturing quality. The invention can be used in particular in the field of MES systems, especially in the field of remote condition monitoring. The previously known approaches have the disadvantage that the features shown above such as a component-oriented detection of crashes and critical events and consideration of manufacturing quality are not used there and thus only a small utilization of the potential performance of the previous system is given. Therefore, a generic integration of methods in the area of remote control monitoring is to be carried out, by means of which evaluation methods optimally adapted to the respective task become possible. Furthermore, a simplified integration of new / optimized evaluation procedures are easily carried out and there is a certain openness of the system. In addition, a component-specific acquisition with consideration of key parameters is possible. Also, generic integration of methods can be done through a simple interface to integrate new methods, and component-wise capture can be implemented to continuously capture critical events including crashes on the controller side, allowing cyclic delivery of events or counters to the GDS , Extending the approach of generic integration of methods to MES systems, ie the integration of arbitrary algorithms for production planning, control, monitoring, maintenance, ...) can fener be realized as an additional measure improving the invention. Also, events may be captured within the controller (ie, in the servers rather than the interface as in the prior art).
