Description

Technical Field

[0001] This invention relates to a method for analyzing electromechanical systems. It also relates to a network structure for analyzing electromechanical systems. Furthermore, it relates to an apparatus for analyzing electromechanical systems. Finally, it relates to a computer program and a computer-readable storage medium for analyzing electromechanical systems. Background Technology

[0002] As electromechanical systems become increasingly complex, targeted maintenance and repair of these systems are becoming more and more difficult. Summary of the Invention

[0003] The task upon which this invention is based facilitates simple and efficient analysis of electromechanical systems.

[0004] The task is solved by means of the features according to the invention.

[0005] According to a first aspect, the present invention is characterized by a method for analyzing an electromechanical system having one or more electromechanical components.

[0006] According to the first aspect, structural data is provided, representing a predetermined structure of a network. The structure has multiple layers, each representing a technical domain of the electromechanical system. A multi-layered network model is generated based on multiple input data regarding the electromechanical system and the predetermined structure. The multi-layered network includes multiple nodes and multiple connections located between each node. Each of the multiple nodes is assigned to one of the multiple layers. The electromechanical system is analyzed based on the multi-layered network.

[0007] This allows for the simplified and efficient display of the functions of an electromechanical system, the failures of those functions, and their impact on the system in a multi-layered network format. Furthermore, it enables the identification and analysis of relationships between different technical domains within the electromechanical system. This can significantly save time and costs for each individual diagnostic or repair situation, for example. Moreover, it is advantageous for the analysis of electromechanical systems during their development phase, such as in the development of robust diagnostic measures and / or diagnostic designs.

[0008] Electromechanical systems, especially complex ones, such as vehicles. Vehicles are preferably single-track or multi-track motor vehicles (such as cars, trucks, transport vehicles, and motorcycles). This results in several advantages explicitly described within the scope of this document, as well as several other advantages that will be understood by those skilled in the art. Particularly significant advantages can be derived when applied to highly or fully automated vehicles. Alternatively, the vehicle can be an aircraft or a vessel, and the method is applied accordingly to aircraft or vessels.

[0009] The intended structure has at least two layers.

[0010] Multilayer network design is used to interconnect domain-based development knowledge in information networks, enabling the use of action chains and tolerance chains to, for example, find the cause of a failure.

[0011] Multiple input data points for electromechanical systems can be provided by (huge, computable) matrices that contain the input data in a networked and coded manner. Matrix representations enable efficient machine processing of multiple input data for the analysis of electromechanical systems. The generation of multi-layered network models allows for manual and / or automatic (further or intermediate) processing of multiple input data to achieve the desired quality and further optimize the analysis.

[0012] Input data can be based on various data from the development process or operation of the electromechanical system.

[0013] Input data includes: fault data configured to define one or more fault states, and / or measurement data configured to define one or more measurements, and / or observation data configured to define one or more symptoms, and / or interface data configured to define one or more interfaces, preferably, the one or more interfaces are configured to connect data from various technical domains of the electromechanical system, and / or maintenance data configured to define one or more maintenance measures, and / or design data configured to define one or more design features, preferably, the one or more design features are configured to map or represent one or more structural features, and / or maintenance data configured to define one or more maintenance measures, preferably, the one or more maintenance measures are configured to associate one or more fault states with one or more maintenance measures, and / or software data configured to define one or more software states, preferably, the one or more software states are configured to associate one or more fault states with one or more measurements, and / or data from signal and / or functional analysis of the electromechanical system.

[0014] Each of the multiple connections represents a relationship between one node and another. For example, a symptom is connected to a fault image if the symptom is associated with the fault image in some way. If there is no association (e.g., "vehicle color" and "heat development"), it can be represented by the corresponding missing connection or the corresponding weight of the connection.

[0015] Data from the development process includes, for example: Diagnostic Trouble Codes (DTCs) / Health Indicators (such as fault data) lists containing possible fault memories and possible measurements. So-called Controller Description Files (SGBDs) contain descriptions of which diagnostic information is coded on the controller, where, and how. DTCs describe fault memories, particularly those related to environmental conditions, and indicate the presence (or absence) of faults; additionally, HIs indicate the degree of fault. Service instructions (such as maintenance data) contain service procedures for resolving issues that need to be addressed quickly, other than test plans. Test plans (e.g., included in maintenance data) can be understood as substantially similar to service instructions but already stored in the diagnostic tester. Circuit diagrams (such as design data) contain electrical connections and pinouts (e.g., pin assignments, pinouts), which can be displayed in a multi-layered network, similar to faults in the circuit. Mechanical design data contains mechanical connections between parts and their tolerances. Based on this, errors in the balance equations can be displayed in a multi-layered network. Failure Mode and Effects Analysis (FMEA) / Fault Tree Analysis (FTA), such as fault data, includes the impact of mechanical failures on observable symptoms and can be directly visualized as connections in a multi-layered network. FMEA is typically mechanical in nature, while Fault Tree Analysis (FTA) is usually based on E / E failures. Software documentation (such as software data) details the impact of error signals on observable symptoms and can be used similarly to FMEA.

[0016] Multilayer networks, for example in Neo4J format, are stored in a preferred graph structure for further processing.

[0017] Analysis of electromechanical systems can, for example, determine which electromechanical component is related to which DTC (diagnostic tic), and / or which error images have not been diagnosed, and / or the frequency of DTC occurrence when the electromechanical system has predetermined system characteristics.

[0018] Analysis of electromechanical systems can, for example, generate subnetworks of multilayer networks.

[0019] According to one alternative implementation, each of the plurality of connections includes one or more of the following connection parameters: a first value designed to define whether the corresponding connection is a directional connection. If the corresponding connection is a directional connection, the connection parameter includes a second value. The second value is designed to define the direction of the corresponding connection. This direction can take one of two unidirectional values ​​and one bidirectional value. A third value is designed to define whether the corresponding connection is a weighted connection. If the corresponding connection is a weighted connection, the connection parameter includes a fourth value. The fourth value is designed to define the weight of the corresponding connection.

[0020] This allows for a simple, efficient, and accurate representation of the relationship between two nodes. Furthermore, it enables the linking of the technical domains of electromechanical systems.

[0021] For example, weights have values ​​between 0% and 100%. Alternatively or additionally, the one or more connection parameters include textual information designed to define the respective connections.

[0022] In another alternative implementation, the multi-layer network has a component layer. Each node assigned to the component layer includes one or more component attributes and represents a corresponding electromechanical component and its electromechanical operation. The component layer represents the relationships between the corresponding electromechanical components.

[0023] The component layer represents the first technical domain of the electromechanical system. The first technical domain includes the one or more electromechanical components and their corresponding electromechanical modes of operation, as well as the relationships between the corresponding electromechanical components.

[0024] Therefore, the first technical domain can be analyzed simply and efficiently and associated with other technical domains of the electromechanical system.

[0025] The one or more component attributes include, for example, an identification attribute that uniquely identifies the corresponding node by assigning a unique sequence of numbers and / or letters, and / or a type attribute that marks the corresponding node as an electromechanical component, and / or a name attribute in text form representing the corresponding node, and / or a failure rate and / or a failure probability and / or a cost value of the electromechanical component or similar attributes.

[0026] According to another alternative implementation, the multi-layer network has a functional layer. A corresponding node assigned to the functional layer includes one or more functional attributes and represents a corresponding function of the electromechanical system. The functional layer represents the functional process between the corresponding functions. If the multi-layer network has a component layer, then the corresponding connections between nodes assigned to the functional layer and nodes assigned to the component layer respectively represent that the corresponding function represented by the corresponding node of the functional layer is performed by the corresponding electromechanical component represented by the corresponding node of the component layer.

[0027] The functional layer represents the second technical domain of the electromechanical system, which includes the representation of the corresponding functions and the functional processes between the corresponding functions of the electromechanical system.

[0028] Therefore, the second technology domain can be analyzed simply and efficiently and associated with other technology domains of the electromechanical system.

[0029] The corresponding functions include the hardware and / or software functions of the electromechanical system and / or the hardware and / or software functions of the corresponding electromechanical components.

[0030] The functional processes between corresponding functions include Boolean algebra operations, especially operations using operators such as "AND" and / or "OR".

[0031] The one or more functional attributes include: identification attributes and / or type attributes that mark the corresponding node as a function of the electromechanical system, and / or name attributes, and / or failure rate and / or failure probability and / or weighted attributes representing the weight of the corresponding function relative to other functions of the electromechanical system and / or system-level attributes representing which system level of the electromechanical system the corresponding function belongs to, or similar attributes. The system level of the electromechanical system may be "drive unit" and / or "torque controller" and / or "torque converter" or the like.

[0032] According to another alternative implementation, the multi-layer network has a fault layer. A corresponding node assigned to the fault layer includes one or more fault attributes and represents a corresponding fault state relating to a corresponding function of a corresponding electromechanical component. The fault layer represents a relationship between corresponding fault states. If the multi-layer network has a functional layer, the corresponding connection between a node assigned to the fault layer and a node assigned to the functional layer represents that a corresponding fault state represented by a corresponding node in the fault layer is assigned to a corresponding function represented by a corresponding node in the functional layer.

[0033] The fault layer represents the third technical domain of the electromechanical system, which includes the corresponding fault states and the relationship between the corresponding fault states and the functions of the one or more electromechanical components.

[0034] Therefore, the third technology domain can be analyzed simply and efficiently and associated with other technology domains of the electromechanical system.

[0035] The one or more fault attributes include: identification attributes and / or type attributes that mark the corresponding node as a fault state of the electromechanical system, and / or name attributes, and / or probability or similar attributes that represent the probability value of the occurrence of the corresponding fault state.

[0036] According to another alternative implementation, the multilayer network has a diagnostic layer. A corresponding node assigned to the diagnostic layer includes one or more diagnostic attributes and represents a corresponding diagnostic result of the electromechanical system. The diagnostic layer represents the relationship between the corresponding diagnostic results. If the multilayer network has a fault layer, the corresponding connection between a node assigned to the diagnostic layer and a node assigned to the fault layer represents that the corresponding diagnostic result represented by the corresponding node of the diagnostic layer is related to the identification of the corresponding fault state represented by the corresponding node of the fault layer.

[0037] The diagnostic layer represents the fourth technical domain of the electromechanical system, which includes the representation of the relationship between the corresponding diagnostic results and the corresponding diagnostic results of the electromechanical system.

[0038] Therefore, the fourth technology domain can be analyzed simply and efficiently and associated with other technology domains of electromechanical systems.

[0039] Diagnostic results may include fault images, such as DTCs showing the presence or absence of a fault (e.g., binary, "yes" / "no", "present" / "absent") or so-called "health indicators" (HIs) that represent component status (e.g., green / yellow / red indicating "system normal" / "system altered" / "serious fault"). The difference is that DTCs represent binary fault states, while HIs constitute a continuous fault severity measurement instrument that can represent the degree of fault (and may include, for example, one or more measurements).

[0040] If the corresponding diagnostic result includes DTC, then the one or more diagnostic attributes include: identification attributes and / or detection level and / or repair cost attributes or similar attributes representing the repair cost amount determined based on the diagnostic result.

[0041] If the corresponding diagnostic result includes HI, then the one or more diagnostic attributes include: identification attributes and / or type attributes that mark the corresponding node as HI, and / or name attributes, and / or system-level attributes or similar attributes that represent which system level of the electromechanical system the corresponding diagnostic result belongs to.

[0042] According to another alternative implementation, the multilayer network has a symptom layer. A corresponding node assigned to the symptom layer includes one or more symptom attributes and represents a corresponding symptom of the electromechanical system. The symptom layer represents the relationship between the corresponding symptoms. If the multilayer network has a fault layer, the corresponding connection between a node assigned to the symptom layer and a node assigned to the fault layer represents the identification of a corresponding symptom represented by a corresponding node in the symptom layer and a corresponding fault state represented by a corresponding node in the fault layer.

[0043] The symptom layer represents the fifth technical domain of the electromechanical system, which includes the corresponding symptoms and the relationship between the corresponding symptoms of the electromechanical system.

[0044] Therefore, the fifth technology domain can be analyzed simply and efficiently and associated with other technology domains of electromechanical systems.

[0045] Symptoms represent corresponding characteristics and / or signs of an electromechanical system. For example, symptoms may include power loss and / or fault messages and / or inability to select a driving speed level and / or abnormal sounds, such as rattling or similar noises.

[0046] The one or more symptom attributes include: identification attributes and / or type attributes that mark the corresponding node as a symptom of an electromechanical system, and / or name attributes or similar attributes.

[0047] According to another alternative implementation, the multi-layer network has a system characteristic layer. A corresponding node assigned to the system characteristic layer includes one or more system characteristic attributes and represents a corresponding system characteristic of the electromechanical system. The system characteristic layer represents the relationship between the corresponding system characteristics. If the multi-layer network has a fault layer, the corresponding connection between a node assigned to the system characteristic layer and a node assigned to the fault layer represents the identification of a corresponding system characteristic represented by a corresponding node in the system characteristic layer and a corresponding fault state represented by a corresponding node in the fault layer.

[0048] The system characteristic layer represents the sixth technical domain of the electromechanical system. The sixth technical domain includes the representation of the corresponding system characteristics and the relationship between the corresponding system characteristics of the electromechanical system.

[0049] Therefore, the sixth technology domain can be analyzed simply and efficiently and associated with other technology domains of electromechanical systems.

[0050] System characteristics include, for example, a certain variant and / or model of an electromechanical system and / or certain electromechanical components of an electromechanical system and / or the production period of an electromechanical system and / or the color or similar characteristics of an electromechanical system.

[0051] According to another alternative implementation, the multi-layer network has an environment layer. A corresponding node assigned to the environment layer includes one or more environmental attributes and represents a corresponding characteristic of the environment in which the electromechanical system operates. The environment layer represents the relationships between these corresponding environmental characteristics. If the multi-layer network has a fault layer, the corresponding connection between a node assigned to the environment layer and a node assigned to the fault layer represents the identification of a corresponding fault state represented by a corresponding node in the fault layer, in relation to a corresponding characteristic of the environment represented by the corresponding node in the environment layer.

[0052] The environment layer represents the seventh technical domain of electromechanical systems. The seventh technical domain includes the corresponding characteristics of the environment and the representation of the relationships between the corresponding characteristics of the environment.

[0053] Therefore, the seventh technology domain can be analyzed simply and efficiently and associated with other technology domains of electromechanical systems.

[0054] The one or more environmental attributes include: identification attributes and / or type attributes that mark the corresponding node as a corresponding characteristic of the environment, and / or name attributes or similar attributes.

[0055] The environment represents the geographical area in which the electromechanical system operates.

[0056] Environmental characteristics include, for example, the characteristics of a geographic area, temperature range, and / or ambient temperature or similar values.

[0057] According to another alternative implementation, the multi-layer network has a system usage layer. The corresponding nodes assigned to the system usage layer include one or more system usage attributes and represent corresponding operating modes of the electromechanical system. The system usage layer represents the relationships between the corresponding operating modes of the electromechanical system. If the multi-layer network has a fault layer, the corresponding connections between the nodes assigned to the system usage layer and the nodes assigned to the fault layer represent: the identification of the corresponding operating mode represented by the corresponding node of the system usage layer and the corresponding fault state represented by the corresponding node of the fault layer.

[0058] The system uses a layer to represent the eighth technical domain of the electromechanical system. The eighth technical domain includes the corresponding operating modes of the electromechanical system and the representation of the relationships between the corresponding operating modes of the electromechanical system.

[0059] Therefore, the eighth technology domain can be analyzed simply and efficiently and associated with other technology domains of the electromechanical system.

[0060] Operating mode can also be referred to as the usage mode of electromechanical system.

[0061] Operating mode represents information about the electromechanical system user, such as driver profile in the case of a vehicle, and / or information about how the electromechanical system is used, such as whether the vehicle is mainly operating on short distances or on highways, or similar information.

[0062] According to another alternative implementation, the multilayer network has a descriptive layer (or guidance layer). The corresponding nodes assigned to the descriptive layer include one or more descriptive attributes and represent corresponding descriptions for troubleshooting and / or analysis of the electromechanical system. The descriptive layer represents the relationship between the corresponding descriptions for troubleshooting and / or analysis of the electromechanical system. If the multilayer network has a component layer, the corresponding connection between the nodes assigned to the descriptive layer and the nodes assigned to the component layer represents that the corresponding electromechanical component represented by the corresponding node of the component layer is related to the troubleshooting and / or analysis of the electromechanical system based on the description represented by the corresponding node of the descriptive layer. If the multilayer network has a functional layer, the corresponding connection between the nodes assigned to the descriptive layer and the nodes assigned to the functional layer represents that the corresponding function represented by the corresponding node of the functional layer is related to the troubleshooting and / or analysis of the electromechanical system based on the description represented by the corresponding node of the descriptive layer. If the multilayer network has a fault layer, the corresponding connection between the nodes assigned to the descriptive layer and the nodes assigned to the fault layer represents that the corresponding fault state represented by the corresponding node of the fault layer is related to the troubleshooting and / or analysis of the electromechanical system based on the description represented by the corresponding node of the descriptive layer. If the multi-layer network has a diagnostic layer, the corresponding connections between nodes assigned to the description layer and nodes assigned to the diagnostic layer represent: the corresponding diagnostic results represented by the corresponding nodes of the diagnostic layer are related to the troubleshooting and / or analysis of the electromechanical system based on the descriptions represented by the corresponding nodes of the description layer. If the multi-layer network has an environment layer, the corresponding connections between nodes assigned to the description layer and nodes assigned to the environment layer represent: the corresponding characteristics of the environment represented by the corresponding nodes of the environment layer are related to the troubleshooting and / or analysis of the electromechanical system based on the descriptions represented by the corresponding nodes of the description layer.

[0063] The description layer represents the ninth technical domain of the electromechanical system. The ninth technical domain includes the corresponding descriptions for troubleshooting and / or analysis of the electromechanical system, as well as the representation of the relationships between the corresponding descriptions for troubleshooting and / or analysis of the electromechanical system.
