    SYSTEM FOR MONITORING A TECHNICAL DEVICE
    The invention relates to a system and a method for monitoring a technical device, in particular a drive device, wherein a visual representation for monitoring the technical device is generated and output. More particularly, the invention relates to a system and method for preparing and displaying information relating to a technical device for effective processing by a user.
    An example of a technical device to be monitored is an internal combustion engine during the test phase or calibration phase (or application phase) in which test engineers check the control of the internal combustion engine for the various possible applications and provided with control data and possible in a usually iterative process find optimal settings.
    An understanding of the functions of the controller, in particular the control software, is incessant for the test engineers. Therefore, documentation is usually provided by the respective developers of the control or the control software. During the software verification and calibration phase of a technical device, the test engineers access a running application via various aids. Thus, on the one hand, measuring devices are used to record measured values and, on the other hand, a calibration device is used to access variable parameters and / or parameter fields.
    In order to carry out the testing, measuring and calibration tasks, the test engineer has to merge information which emerges from the documentation and information which the calibration device or the control itself provides. The resulting workflow, switching between documentation, measuring equipment and calibration equipment, is generally cumbersome, confusing and time consuming.
    DE 196 33 870 A1 relates to a method for the automatic production of specific manufacturing documents for a product to be built from components based on information from the specification of the product and a generic representation of the product variation spectrum.
    EP 1 474 927 B1 relates to a method and a system for displaying and / or viewing image streams or for effectively displaying the same. In order to improve the information recording or to prevent the physiological filtering out of individual images which are displayed in the image stream, it is provided here to divide an image stream into two subset image streams and display them simultaneously on a monitor, each subset image stream being a separate subset contains images from the original image stream.
    It is an object of the invention to simplify and improve the monitoring of a technical device by a human. A further object of the invention is to provide an improved controllability of the technical device due to the improved monitoring.
    This object is achieved by a system and a method according to the independent claims. Advantageous embodiments are claimed in the subclaims. The teaching of the claims is expressly made the content of the description.
    A first aspect of the invention relates to a system for monitoring a technical device, in particular a drive device, which comprises a detection means, in particular an image memory means for reading a first visual representation, in particular a signal flow plan, wherein the first visual representation information with respect to includes at least one adjustment parameter and / or at least one measurement parameter of a controller, which is configured to control the device. Furthermore, the at least one adjustment parameter and / or the at least one measurement parameter is suitable for characterizing a state of the device. Preferably, the system further comprises a scanning means for detecting at least one symbol, in particular a caption, in the visual representation, in particular by means of optical character recognition. Furthermore, the system preferably has a database for associating at least one setting parameter and / or at least one measurement parameter of the current application with the at least one recognized symbol. An interface to the controller preferably exists in the system for detecting a value of the at least one adjustment parameter and / or the at least one measurement parameter of the controller. More preferably, the system comprises image generating means for generating a second visual representation, wherein the image generating means is preferably coupled to the controller such that information of the at least one adjustment parameter and / or the at least one measurement parameter is displayed with at least a portion of the first visual representation becomes. The first visual representation here is preferably subjected to image processing and may differ from the read-in first visual representation graphically, in particular in color, shape and / or size of individual symbols and graphic elements. Information conveyed by the first visual representation, however, preferably remains at least substantially preserved. Further preferably, the image generating means is coupled to the controller in such a way that the value of the at least one adjustment parameter and / or the at least one measurement parameter together with a name, in particular the respective detected symbol, the at least one adjustment parameter and / or the at least one measurement parameter , especially in a tabular view. Finally, the system preferably comprises an image display means, in particular a screen for reproducing the generated second visual representation for monitoring the technical device.
    E in the second aspect of the invention relates to a method for monitoring a technical device, which preferably comprises several of the following steps: reading a first visual representation, in particular a signal flow plan, wherein the information relating to at least one adjustment parameter and / or at least one Includes measurement parameters of an application configured to control the device, and wherein the at least one adjustment parameter and / or the at least one measurement parameter is adapted to characterize a state of the device; Recognizing at least one symbol, in particular a caption, in the first visual representation, in particular by means of optical character recognition; Assigning at least one adjustment parameter and / or at least one measurement parameter to the at least one recognized symbol; Detecting a value of the at least one adjustment parameter and / or the at least one measurement parameter of the controller; Generating a second visual representation, which is coupled to the application in such a way that the value of the at least one adjustment parameter and / or the at least one measurement parameter with the first visual representation, in particular in the first visual representation and / or these blends displayed and / or generating a second visual representation which is coupled to the application in such a way that the value of the at least one adjustment parameter and / or the at least one measurement parameter together with a designation, in particular the respective recognized symbol, of the at least one adjustment parameter and / or the at least one measurement parameter, in particular in a tabular view, is displayed; and outputting, in particular reproducing, the generated second visual representation for monitoring the technical device.
    A system according to the invention has a plurality of components, which may be designed both as a software module and as a hardware module. Preferably, the components can be arranged in one device. Preferably, however, the components are distributed over several devices.
    A technical device according to the invention is a real device or a simulated and / or emulated device.
    A visual representation within the meaning of the invention is an illustration which can be visually perceived by a user. It is in particular a text or a graphic representation.
    A control according to the invention means both a control without feedback of a measured variable as well as a control with feedback of a measured variable. The same applies to the term "tax". The control can be realized in particular by hardware and / or software. Preferably, this has a control unit which has at least one microprocessor, more preferably at least one data memory.
    A symbol according to the invention is in particular a letter, a morpheme, a word, a graphic, a logo or metadata, which are stored in a documentation as invisible information.
    A detection means according to the invention is set up to be able to include a visual representation, in particular by means of a scanner, a screenshot or an optical camera.
    A scanning means in the context of the invention is set up to scan a visual representation. In particular, in this case a digital representation of the visual representation is processed by means of a software algorithm so that symbols and labels can be recognized. Preferably, this means of optical character recognition OCR (Optical Character Recognition) are used.
    An image generating means according to the invention can generate or generate a visual representation. In this case, in particular digital data are generated, which can be converted by an image display means into a representation.
    An application in the sense of the invention is at least a functional part or function of software which, when executed by a computer, causes it to execute operations defined by the application.
    The invention is based in particular on the recognition that human information processing, that is the perception, detection and processing of relevant information in complex man-machine systems, in which information from a variety of different parameters, in particular by means of instruments, displays , Control lights, etc., must be monitored by a human, plays an important role.
    Control surfaces or user interfaces of complex man-machine systems, as used for monitoring technical devices, e.g. A drive device having an internal combustion engine can be used, are usually designed in a row-oriented or column-oriented table-like representation. The individual parameter fields, which show values of measuring parameters or setting parameters, are usually marked with the parameter names.
    The measurement parameters and setting parameters relevant for a specific technical method or a specific function must be selected by a user himself from this representation.
    At the same time extensive technical documentation is often available for such technical devices as the drive device. With regard to drive devices, signal flow diagrams are generally included in these documentations, which provide a user with detailed information about the relevance and the functional relationship of individual parameters and functional blocks with respect to a technical procedure or a specific function.
    According to the labels in the first visual representation, in particular a signal flow chart, a table, description o.ä., The respective parameters are assigned and generated a second visual representation and output, which the user the information of the parameter values and the first visual Representation represents coupled.
    Here, the invention adopts the resource model of information processing (for example, Kahnemann's simple resource model, Wickens's multiple resource model) in which a basic assumption is that information processing costs man's mental capacity. This mental capacity is limited in each person and varies depending on a number of other factors. Thus, several activities can be carried out simultaneously if they can not use the same human resources or the resources can be shared. For example, in accordion playing it is possible to simultaneously read the notes and to operate or pump the keys. In this case, reading the notes relies on the visual system, but the button operation / pumping relies on the hand-arm motor system. At the same time an accordion player can even walk, which is done by his leg motor skills. When driving in a foreign city, a completely different picture emerges: Here, the driver must both orient himself and drive the vehicle. When orienting, the driver must read the map and scroll through the map, using both the visual system and the hand or arm motor. When driving, the driver must observe the traffic and steer / switch, so also accesses his visual system and the hand or arm motor. This leads to massive conflicts in human information processing, resulting in a massive increase in the probability of an accident.
    The system according to the invention and the method according to the invention make it possible to display the information consisting of user interfaces of the control of the technical device, which information is displayed in execution time, in particular in online or real-time operation, with the information about the relevant parameters and / or the functional relationships, which can be taken in particular Signalflussplänen connect.
    By displaying only relevant parameter values with respect to the first visual representation, a user can directly access relevant information without first having to tediously extract the applicable parameters from a confusing list. By displaying the individual relevant parameter values in the process sequence of the control or the technical device, the user can already assess in advance the influence of a change of the parameter on sub-processes or subsystems but also on the overall process or the overall system and, at least qualitatively, a sensitivity analysis make.
    As a result, the physiological human information processing significantly improves since the visual system of the user data from two visual sources, which he had previously to process in parallel with his visual system, are now provided in a single representation. Resource conflicts in the information processing of the user are avoided in this way. This is particularly important if the user is exposed to other sensory stimuli, such as the noise of a test bench, the steering of a vehicle to be tested or even a conversation with colleagues.
    The inventive system and method generates an ergonomic user interface for the user or a user interface for a complex man-machine system such as a controller or a calibration device for monitoring and controlling technical devices. In particular, this makes it possible to group and arrange adjustment parameters and measurement parameters according to the respective function and the general process sequence, which makes the representation comprehensible to the user. Preferably, the parameters are spatially associated with the corresponding functions in a signal flow plan or the symbols and / or identifiers designating them. In this way, multiple interpretations can be reduced and there is a clear allocation of information. By these measures, the information for the user is made detectable or processable.
    Also, the user is preferably presented additional information in the usual environment, for example in a signal flow plan. As a result, the information recording or its recognizability for the user is increased.
    In particular, it is possible with the system according to the invention and the method according to the invention, for example in vehicle development, to connect the development phase and the test phase with one another. In particular, the control of an internal combustion engine here represents a complex man-machine system. Thus, a signal flow plan, which the developers have outlined for controlling an internal combustion engine to be optimized, are used directly on the test bench, by means of the inventive system and the inventive method Values of setting parameters and measuring parameters are superimposed in the signal flow diagram. The user, in this case the test engineer, can directly derive the functional relationship between the individual parameters from the generated second visual representation, make conclusions with regard to an optimization of the internal combustion engine and make appropriate provisions on the test bench, for example adjusting the adjustment parameters, for further optimization to reach.
    Information relating to at least one adjustment parameter and / or at least one measurement parameter of the control is inventively preferably detected by reading, in particular scanning, performing a screenshot or filming, the first visual representation. This makes it possible to extract this information directly from a documentation, in particular a documentation available as a digital file or printed. As a result, a system independence is achieved so that technical devices can be monitored by means of controls and calibration systems of various providers.
    In an advantageous embodiment, the inventive system comprises an input means, in particular a keyboard, to input values for the at least one setting parameter, wherein the input means is coupled to the controller in such a manner that the value of the at least one setting parameter is variable. This development of the system according to the invention not only the perceptibility or human information processing of the information of a complex man-machine system for controlling a technical device allows, but a user can also make changes directly in the generated second visual representation. This allows a particularly simple and clear operation of the technical device and in turn prevents resource conflicts with the user, since this does not have to monitor two information sources, for example an indicator with actual values and an input surface of nominal values, but all information is available on one surface gets asked.
    In a further advantageous embodiment of the system according to the invention, the controller is part of the device or part of a calibration system. The system according to the invention and the method according to the invention can be used both in the representation of measured values and the programming of the direct control of the technical device or also in the indirect representation of measured values or the device of the technical device or its control via a calibration system, in the case of an engine test bench For example, the INCA® system from ETAS GmbH. Both a control of a technical device and a calibration system are in particular a complex man-machine system.
    In a further advantageous embodiment of the system according to the invention, the image generating means is designed in such a way that in the second visual representation when displayed on the image display means, the values of the at least one adjustment parameter and / or the at least one measurement parameter in spatial proximity or instead of at least one recognized icon. This embodiment of the invention realizes the law of proximity known from the theory of human information processing. This means to present related information in the immediate vicinity. In this case, stimuli that are located close to one another within a configuration are considered to belong together rather than to be distanced from one another. This embodiment of the invention further improves the reception of information, in particular the recognition of affiliation, especially relationships.
    The features and advantages described above in connection with the first aspect of the invention of a system according to the invention also apply with respect to the second aspect of the invention of a method according to the invention and vice versa.
    Accordingly, in an advantageous embodiment of the method according to the invention, the second visual representation of the application further coupled in such a way that the value of the at least one adjustment parameter is variable.
    Accordingly, the application in a further advantageous embodiment of the method according to the invention is also part of a control software of the device or part of a calibration software for the device.
    In a further advantageous embodiment of the method according to the invention, at least the generation of a second visual representation is carried out when the application is carried out, and the detected values correspond to the respectively present values. This embodiment of the method according to the invention allows operation at the execution time of the application or the technical device itself, in particular in online or real-time operation, wherein the second visual representation in the respective operating state of the technical device to be monitored constantly adapted and / or updated with a predetermined periodicity becomes.
    In a further advantageous embodiment of the method according to the invention, according to the first aspect of the invention, the values of the at least one adjustment parameter and / or the at least one measurement parameter are displayed in spatial proximity or instead of at least one recognized symbol.
    In a further advantageous embodiment, the inventive method further comprises the operation of extracting the belonging to the at least one symbol at least one measurement parameter or the at least one setting parameter from a predefined database, in particular a mapping file on. This embodiment of the method according to the invention is used in particular when the information about the assignment of several parameters to the symbols in a database / file is stored.
    In a further advantageous embodiment of the method according to the invention, the at least one adjustment parameter and / or the at least one measurement parameter is detected at a respective respective interface, in particular a channel of the application or the device.
    In a further advantageous embodiment of the method according to the invention further comprises the following steps: reading a control surface of the application, in particular a kind of table; and extracting the at least one detected symbol associated with the at least one set parameter and / or measurement parameter from the control surface; and / or extracting the set value of the at least one adjustment parameter and / or the measured value of the at least one measurement parameter from the control surface. This refinement of the method according to the invention is used in particular when assignment instructions between parameters and symbols are not provided in a file, but are contained only as context information in a documentation or a control surface of the application, in particular of a complex man-machine system. This process also greatly simplifies the process of collecting information for a user, since he does not have to find out about these assignment rules himself.
    In a further advantageous embodiment of the method according to the invention, this further comprises the step of detecting a change in the at least one setting parameter and the generated second representation, in particular by entering a user. This step makes it possible, especially in real time
    Perform calibrations or applications directly in the second visual representation.
    In a further advantageous embodiment of the inventive method, changing the value of at least one adjustment parameter in the second visual representation causes a change of the at least one adjustment parameter in a control surface of the application and directly on a corresponding channel of the application or the device. In accordance with the first aspect of the invention, the calibration of the technical device can likewise be carried out directly in the second visual representation.
    In a further advantageous embodiment of the method according to the invention, the device is an internal combustion engine and the at least one adjustment parameter, in particular a throttle position and / or a fuel quantity and the at least one measurement parameter, in particular a speed and / or torque of the device. The inventive method according to the second aspect of the invention as well as the inventive system according to the first aspect of the invention are particularly well suited to the optimization of internal combustion engines or drive systems.
    In a further advantageous embodiment of the method according to the invention, this further comprises the following steps: detecting a logic with respect to a signal flow in the visual representation; and matching the detected logic with an algorithm of the application, wherein the mapping from the at least one adjustment parameter and / or the at least one measurement parameter to the at least one detected symbol is performed based on the matching. With this embodiment of the method according to the invention not only the functional relationship between individual symbols or parameters is taken from the first visual representation, but also the assignment of symbols to parameters can be made automatically due to the detected logic.
    Further features, advantages and possible applications of the invention will become apparent from the following description taken in conjunction with the figures. In the drawings: Fig. 1a is a partially schematic representation of a first embodiment of a system according to the invention for monitoring a technical device; Fig. 1b is a partial schematic representation of an enlarged first visual
    Representation of Fig. 1a; Fig. 1c is a partial schematic representation of an enlarged second visual
    Representation of Fig. 1a; Fig. 2 is a partially schematic representation of a second embodiment of the system according to the invention for monitoring a technical device; and Fig. 3 is a partially schematic block diagram of one embodiment of the method of the invention for monitoring a technical device.
    The invention will be described with reference to the figures in relation to an application of the invention in a calibration of an internal combustion engine 2. However, the invention can also find application in other areas in which technical devices must be monitored. An example of a setting parameter in the application described is the throttle position, an example of a measurement parameter in this case is the speed or torque of the internal combustion engine.
    In the process verification and calibration phase in automotive development, in particular software-in-the-loop environments (SiL), hardware-in-the-loop systems (HiL), component test benches, vehicle test benches or even vehicle environments are used Commitment. In particular, functional schemes 4, in particular graphic signal flow plans, are used in this working environment in order to be able to understand the functional relationship between individual parameters. In this case, workflows are frequently encountered in which, as described above, must be switched back and forth between documentation, measuring equipment and calibration facilities.
    These functional schemes 4 are mostly generated by graphical programming languages, which are also used to implement functions in software. Examples include LabVIEW® or Simulink®. This model-driven engineering has proven to be a highly flexible and practical approach to the software development process. However, the advantages of a graphical representation of the functions are not provided throughout the entire development cycle, including the design and testing phase: In the design phase, a function definition of an application 5 may be provided in graphical form (eg, by means of LabVIEW® or Simulink ®) and tested in simulation environments and pre-calibrated.
    In the test phase, including the calibration phase, the function is present only as a machine code in a control software and is executed in a test environment, usually on a test bench 14. The present machine code usually has no direct connection to the schematic representations 4 developed in the design phase.
    Only the specifically defined labels of the parameters of the control software are usually stored in a so-called mapping file, with which a direct access of the test bench software is made possible to the current application. Access is then preferably via a defined interface.
    A so-called reverse engineering of functional schemes 4 from the generated by graphical programming control software for use in the control of the test bench 14 is eliminated, as this is complicated or without specific information to the respective target platform is not possible. This is not or at least difficult to realize with respect to different systems of different providers.
    Figure 1 illustrates a first embodiment of a system 1 according to the invention of a technical device, which allows graphical representations of the functionalities during the entire development cycle, i. E. not only during the development phase, but also during the testing phase, to be directly involved in the developer's work process. The function of this system 1 will be explained with reference to a workflow of the method 100 according to the invention, as is shown partially schematically in FIG.
    Preferably, together with the control software of a technical device 2, a documentation 17 is provided which contains information about the control software and the technical device 2 both as text 18 and as signal flow chart 4.
    With an image capturing means 3, in particular a video camera, camera, scanner or a screenshot device, which is part of the system 1 according to the invention, the signal flow chart 4 is preferably read 101. In the following, the read signal flow chart 4 of the system 1 with a Scanning means 6 processed to particular symbols, ie Letters, morphemes, words, graphics, logos or even metadata can be recognized in the signal flow diagram 4. Preferably, the system 1 can be identified by means of a database 8, which contains information about the relationships between parameters and symbols, of each recognized symbol 7 For example, the "3Ctc- uSens MaxValid" symbol, which is assigned corresponding parameters 107.
    In a further step, the values of the detected parameters, in particular setting parameters and / or the measuring parameters, which are present in the technical device 2 or its controller 5, are preferably detected 108. For this purpose, the system 1 preferably has an interface 9, via which the system 1 can be connected to the controller 5.
    By means of the now available information about the signal flow diagram 4 and the parameters of the technical device 2, a second visual representation 11 can be generated 109. This is realized by the system 1, preferably by means of an image generating means 10, wherein the second visual representation 11 with the Control 5 and an executed on this application, is coupled in such a way that the respective values, in particular in an ongoing application, in particular in an online or real-time mode, are displayed in the second visual representation 11.
    In this case, the second visual representation 11 preferably has a similar form to the originally read-in signal flow diagram 4, symbols for parameters being supplemented or replaced in particular by their respective values 16. In a further step, this supplemented signal flow diagram 11 is preferably output 110. This is preferably done by rendering using a screen 12 of the system 1 according to the invention, so that a user 19 can perceive the supplemented signal flow diagram 11.
    In the supplemented signal flow diagram 11, the parameter values 16 are preferably displayed in close proximity or even instead of the symbols 7. In this way, it is ensured, in particular, that a symbol 7 or a functional block of the signal flow diagram is regarded as belonging to the correspondingly associated parameter value 16 by the user 19.
    Further preferably, the supplemented signal flow diagram 11 is coupled to a controller 5 or an application, in particular a software, of this controller 5 in such a way that the values of the displayed parameters in the supplemented signal flow diagram 11 can be changed.
    For this purpose, the system according to the invention preferably has a user interface 10, in particular an input means or a keyboard, with which the user 19 can enter values for the system 2 into the system 1 for at least one setting parameter of the technical device 2. In a further step, the system 1 then detects a change in the value of the adjustment parameter in the supplemented signal flow diagram 11 111. This preferably also causes an adjustment of the value of the adjustment parameter in the application, the controller 5 of the device 2 or the device 2 itself. The signal connection In this case, the signal transmission can be effected either by an input into a control surface 15 of the application or transmitted directly via a corresponding channel.
    Preferably, an assignment 107 of a parameter to a symbol 7 is made on the basis of information stored in a database 8. From these, the one or more parameters corresponding to a symbol 7, for example the symbol "3Ctc-uSens MaxValid" in FIGS. 1a and 2, are extracted 103a.
    Alternatively or additionally, the system 1 may also include means for detecting logic with respect to a signal flow in the signal flow diagram 4 103b-1. In a further step, the detected logic is then preferably matched with an algorithm of the application 103b-2. In this way, the respective parameter of the application can be linked with the associated symbol 7 in the signal flow diagram. The assignment of parameters to symbols 7 identified in the signal flow diagram 4 can then be made on the basis of this match 103b-2. The assignments derived in this way are preferably stored in a database 8, preferably an association file is created therewith.
    The recognized logic can in turn be used to represent the signal flow (for example with a bold red line) and thereby an even better or corrected visualization of the signal flow chart 4 can be achieved.
    If the recognized logic is transferred into a programming language or a machine code, the result is a subsystem which can be simulated. At this then offline examinations could be carried out and thus the function checked or adjustment parameters changed. This corresponds to a type of reverse engineering based on the documentation.
    In the embodiments shown in FIGS. 1 a and 2, the reproduction of the supplemented signal flow diagram 11 takes place on a computer screen 9, in particular on a screen of a tablet computer, a mobile telephone, etc., on which the information of the signal flowchart 4 for the user 19 linked with parameter values 16 is displayed.
    Preferably, the supplemented signal flow plan 11 can also be output to, preferably via a further interface, to another system by means of a transmission protocol.
    The method 100 according to the invention is preferably repeated by the system 1 according to the invention from the step of recording the values of the parameters of the application or the control in order to adapt, in particular, changes in the values of measuring parameters in the supplemented signal flow diagram 11. In particular, after the detection of a change of a setting parameter in the supplemented signal flow diagram 11, for example by an input of the user 19 via the keyboard 13, a detection of the values of the respective parameters is triggered, in particular against the background that by this means with great probability also the Change measured variables by changing the operating state of the internal combustion engine 2.
    With the method 100 according to the invention and the device 1 according to the invention it is possible, in particular, to use a technical device 2 preferably when the application is carried out, i. during operation or ongoing simulation, in particular in online or real-time operation, to monitor and make changes in the operation of the internal combustion engine 2.
    Preferably, the device 1 according to the invention and the method 100 according to the invention can alternatively or additionally include information from the text 18 or individual words 101 and 102. Corresponding symbols or words in the text can then also be used in a second visual representation 11 associated parameters 107 and output or reproduced 110.
    The signal flow chart 4 or text 18, when reading both in digital form, for example, as a pdf document or as an e-mail, as well as an expression available.
    Another exemplary application of the system 1 and method 100 according to the invention is in controlled systems which are used in simulation environments. These controlled systems are tuned with appropriate parameters in order to reproduce as far as possible the behavior of the real system to be modeled. The associated process of this tuning is also called parameterization.
    In this case, the model quality of a controlled system is generally checked in simulation environments by applying the controlled system to be parameterized with corresponding stimuli using a test signal.
    If a track model 4 of a controlled system is present as a visual representation, measuring and setting parameters of the controlled system can be assigned to the track model and displayed therein.
    By depicting the current measured values and setting parameters in the system model 4, internal model relationships can be understood better and, above all, faster, so that the parameterization can also be accelerated here.
    FIG. 1b shows an enlarged first visual representation 4 in the form of a signal flow diagram from FIG. 1a, which is also valid for the second embodiment according to FIG. 2. Some symbols 7 are provided with reference numerals purely by way of example.
