Description

Technical Field

[0001] This invention relates to a method for supporting the operation of a vacuum component using a support system, the support system comprising at least an image sensor, an evaluation unit, and an output unit. Furthermore, this invention relates to a corresponding support system. Additionally, this invention relates to a computer program product relating to this method and a computer-readable medium. Background Technology

[0002] Vacuum components, such as pumps, valves, measuring instruments, and related connectors and mounts, are widely used in various fields. Information about vacuum components is crucial for proper application and maintenance. However, in most cases, operating conditions and interactions with other components of the entire system in which the vacuum component is installed also have an additional impact on its operation.

[0003] In particular, the connection with other components and environmental conditions are often not given enough attention and can only be evaluated by trained professionals or experienced maintenance technicians, even though there may be identifiable sources of error or potential for application optimization in these areas. Summary of the Invention

[0004] In light of the challenges faced by the prior art, the objective of this invention is to support the safe and efficient operation of vacuum components. Specifically, the objective of this invention is to provide a method, a support system, a computer program product, and a non-transferable computer-readable medium, by which the operation of vacuum components can be supported, particularly by users with any background knowledge and without prior training in vacuum component operation.

[0005] The objective of this invention is achieved through the patent claims. In particular, this objective is achieved through the method of the invention according to claim 1, the support system of the invention according to claim 11, the computer program product of the invention according to claim 14, and the non-transferable computer-readable medium of the invention according to claim 15. Improvements to the invention are derived from the dependent claims, the specification, and the drawings. Wherein, the features and advantages described for the method of the invention are equally applicable to the support system of the invention, the computer program product of the invention, and the medium of the invention, provided that they are technically reasonable and feasible.

[0006] According to a first aspect of the invention, this task is solved by a method for supporting the operation of a vacuum component via a support system, the support system comprising at least an image sensor, an evaluation unit, and an output unit. The method of the invention comprises at least the following steps: a) Capture an image of the vacuum component using the image sensor. b) The evaluation unit evaluates the images captured in step a) to identify the vacuum component in the images. c) The structural type of the vacuum component identified in step b) is determined by the evaluation unit. d) Obtain information on the operation of vacuum components relating to the structural type determined in step c) through the evaluation unit, and e) The information obtained in step d) is provided through the output unit.

[0007] The method of this invention allows even users without specialized knowledge of the relevant vacuum components to obtain information that supports the operation of the vacuum pump. The method of this invention is performed using a support system, preferably the support system of this invention according to the second aspect of the invention.

[0008] The support system used to perform the method of the present invention has all the necessary components and parts. Here, the various components of the support system can be arranged in the same location, for example, even within a common housing. Alternatively, the different components of the support system can also be spatially separated from each other. In its minimum basic configuration, the support system has an image sensor, an evaluation unit, and an output unit.

[0009] Here, the image sensor is designed to capture digital images and, for this purpose, has a corresponding photosensitive detector, such as a CCD or CMOS. Furthermore, the image sensor may also be equipped with imaging optics. In other words, preferably, the image sensor can be designed essentially like a digital camera, or it may be constructed from such a digital camera.

[0010] Furthermore, multiple image sensors may also be present. All the descriptions and explanations below concerning a single image sensor are applicable, in the sense of this invention, to support systems with multiple image sensors.

[0011] The output unit is further configured to output information. This information is preferably visual, so a preferred variant of the output unit is a screen, particularly a touchscreen. Alternatively or additionally, the information may also be presented in the form of sound and then output through a corresponding output unit including a speaker. For audiovisual information, both elements are present as part of the output unit, particularly including both a screen and a speaker. Less commonly, but still possible, the output unit may also be designed as a printer, 3D printer, or similar device, or include such devices, thereby enabling the output of information in printed and / or tactile form.

[0012] The output unit according to the invention may also have an interface for data communication connection, particularly for implementing one of the aforementioned output variations, namely visual, sound, audiovisual, printed, and / or tactile forms, via an external device. Establishing a data communication connection with a vacuum component for data transmission, particularly from the support system to the vacuum component, is also contemplated. Such an interface is preferably provided as an addition to other elements within the output unit that are themselves designed to provide information acquired in step d).

[0013] The evaluation unit is connected in data communication with both the image sensor and the output unit. It has at least a processor designed to receive and evaluate data, particularly data from the image sensor. Based on the received data or its evaluation, the processor can then select appropriate information and provide it to the user by manipulating the output unit.

[0014] The basic flow of each step in the method of the present invention is described below.

[0015] In the first step a), an image of the vacuum component is captured using an image sensor. In other words, after performing step a), the support system provides digitally captured images of the vacuum component.

[0016] The image may include at least a still image. The evaluation unit specifically manipulates an image sensor, which then captures an image in which the vacuum component is included. For this purpose, the image sensor can be oriented, for example, such that the vacuum component is included in the image, preferably completely included, wherein the orientation can be performed automatically by correspondingly manipulating a servo motor, or alternatively or additionally by the user. It is also possible to pre-set and oriented the image sensor accordingly (e.g., during the initial installation of the vacuum component). Prior to step a), a user's request for information can be received.

[0017] In a subsequent step b) of the method of the present invention, the image captured in step a) is transmitted to an evaluation unit for evaluation. The goal of the evaluation is to identify the corresponding vacuum component in the image. This evaluation can be performed in different ways, such as by comparing with example images in a database, applying algorithms for identifying contours and / or objects in an image, or through artificial intelligence. Combinations of various methods are also possible. The vacuum component identified in step b) may be, for example, a pump, valve, measuring instrument, and / or the necessary connectors and mounts. In summary, after completing step b), the information that a vacuum component exists in the image captured in step a) is obtained.

[0018] In the next step c) of the method of the present invention, the information is further specified by determining the structural type of the vacuum component identified in step b) by the evaluation unit. For this step, various different methods can again be used, such as comparing again with the example image, applying algorithms for recognizing contours and / or objects, or artificial intelligence. However, since the vacuum component has already been identified in step b), it is no longer necessary to analyze the entire image when determining the structural type; only the portion of the image that actually shows the vacuum component needs to be analyzed. This allows for a faster determination.

[0019] As a structural type in the sense of this invention, it is necessary to determine, on the one hand, the actual construction form of the vacuum component, i.e., whether it is a pump, valve, or measuring instrument. Furthermore, it is also necessary to determine the specific specifications of the corresponding vacuum component. For example, for a pump that is an identified vacuum component, its structural type must be determined to be (as a non-limiting example) a turbomolecular vacuum pump, and it is also necessary to determine which structural form and series the turbopump belongs to. In other words, after performing step c), it is preferable that the existing vacuum component can be uniquely identified.

[0020] Steps b) and c) listed above can be performed sequentially. Alternatively, steps b) and c) can be performed at least substantially simultaneously, in which case the identification of vacuum components in the image is performed in such detail that the corresponding structural type of the vacuum components is also determined in parallel during the process.

[0021] Furthermore, the following situations may occur: identification of vacuum components in step b) and / or determination of structure type in step c) fail to yield definitive results. In such cases, it can be specified that the evaluation unit triggers a repetition of the previous steps, particularly a repetition of the image capture in step a). Preferably, it can also be further specified that the images are recaptured from a different perspective so that the identification of the present vacuum components in steps b) and c) can be based on different criteria. This can be achieved, for example, by remanipulating the image sensor by the evaluation unit. Alternatively or additionally, the evaluation unit can also issue a request to the user of the support system via the output unit so that the user can perform or at least support the recapture of images, for example by adjusting the orientation of the image sensor. Furthermore, a broader data basis can be provided for the re-execution of steps b) and c) by additionally utilizing the images captured in the first round.

[0022] In summary, after successfully completing step c), information about which type of vacuum component of which structural type is available.

[0023] This enables the evaluation unit to obtain information regarding the operation of vacuum components of the corresponding structural type in the subsequent step d). This information can be, for example, static information such as data sheets, operating instructions, or possible accessories for the identified structural type. Additionally, dynamic information regarding the operation of a specific vacuum component can also be obtained, such as action recommendations, like maintenance recommendations, suggestions or regulations regarding the operating parameters of settable or unsettable vacuum components, or tips on other useful products or consumables.

[0024] Evaluations of vacuum components, such as those concerning proper installation and / or safe, compliant, and particularly optimized operation, may also be conducted during information gathering in step d), where the results of such evaluation (including, where necessary, the evaluation criteria used in the evaluation) may be provided as the information gathered. Based on this evaluation, alternatively or additionally, tips and / or instructions may also be obtained as information, such as warnings when a source of error is identified and / or recommendations for optimizing operating parameters. Information gathering may be performed, for example, through a database query that stores matching information for the corresponding vacuum component structure type.

[0025] Finally, in the last step e) of the method of the present invention, the information acquired in step d) is provided through these output units. Depending on the design of the output units, this can be in visual, audiovisual, purely auditory, and / or physical or tactile form. Thus, in particular, useful or even necessary information for the operation of vacuum components can be provided to users with any background knowledge, especially those untrained in the existing structural types of vacuum components. Providing information via data communication connections is also substantially conceivable. This enables, or at least supports, the operation of the corresponding vacuum components.

[0026] Furthermore, in the method of the present invention, it can be specified that in step a), images of the vacuum component are captured as still images and / or multiple still images and / or videos of the vacuum component from different perspectives. Even a single still image may contain enough detail of the vacuum component to enable identification of the vacuum component in step b) and determination of its structure type in step c). Here, a single still image has particular advantages: it represents only a smaller amount of data compared to multiple still images or even videos. This is especially advantageous when the evaluation unit and the image sensor are physically located in different places and the corresponding data must be transmitted, particularly wirelessly. On the other hand, multiple still images from different perspectives, particularly from different sides, especially videos (in which the vacuum component is preferably also shown from multiple perspectives), provide a significantly expanded data basis for identifying the vacuum component in the images and determining its structure type compared to a single still image. Therefore, in the method of the present invention, image variants selected accordingly based on external circumstances can be used, thus employing the most suitable variant for each.

[0027] Furthermore, the method of the present invention may be characterized in that, in step b), in order to identify the vacuum component and / or in step c), in order to determine the structural type of the vacuum component, the evaluation unit evaluates the image with respect to identification features, wherein at least one of the following features is preferably used as the identification features: - Nameplate - Label, - QR code, - Outline, - Three-dimensional shape, - The presence and / or arrangement of sub-components of the vacuum component. - The presence and / or arrangement of other elements connected to the vacuum component.

[0028] This list is not exhaustive, and other suitable features can be used as identification features.

[0029] Nameplates and / or labels are particularly simple yet generally unambiguous features, and they are especially helpful in identifying the structure type. Similarly, QR codes placed on or at least near vacuum components and identifiable in images can also contain information that identifies the structure type of the vacuum component or at least significantly simplifies identification.

[0030] The three-dimensional shape of a vacuum component (its two-dimensional projection perpendicular to the image sensor's line of sight represents the outline of the imaged vacuum component) can include, for example, the orientation of edges, protrusions, and / or recesses in the appearance of the vacuum component. These features can be used to identify the vacuum component itself or to determine its structural type.

[0031] Furthermore, different structural types of vacuum components may differ in the presence or absence of various sub-components, and / or the arrangement of these sub-components within the vacuum component's basic structure. These sub-components may be, for example, integrated displays or input areas, but could also be cooling units, fans, gas interfaces, or similar components. Evaluating images in relation to these sub-components thus makes it possible to distinguish the structural types of vacuum components that are otherwise very similar.

[0032] A similar situation applies to other components connected to the vacuum component. Unlike sub-components, these components are not part of the vacuum component, but may still be specific to the individual structural type of the vacuum component. This includes, for example, external control devices or power supply devices connected to the vacuum component, which in particular can infer the internal structure of the vacuum component and thus the corresponding structural type.

[0033] In summary, evaluating images based on identifying features can improve the identification of vacuum components, especially in determining the structural type.

[0034] Furthermore, the method of the present invention can also be designed such that, in step a), the surrounding environment of the vacuum component is additionally captured in an image, wherein, particularly in steps b) and / or c), the surrounding environment captured in step a) is analyzed, and wherein, in step d), information is additionally obtained based on the results of the analysis of the surrounding environment, wherein preferably the surrounding environment captured in step a) is analyzed according to at least one of the following criteria: - Installation location, - The level of pollution in the surrounding environment, - Installation orientation, - Fixing the vacuum components - The distance between the vacuum component and objects in the surrounding environment. - Sub-components of the vacuum system and their characteristics - Other components connected to the vacuum component and their characteristics, particularly power supply and / or gas supply and / or exhaust.

[0035] This list is not exhaustive, and other appropriate criteria can be used to analyze the surrounding environment.

[0036] The surrounding environment in the sense of this invention refers specifically to the content contained in, but not representing, the vacuum component itself, in all images captured in step a). Capturing a certain amount of the surrounding environment is generally unavoidable as long as the vacuum component does not completely fill the image. However, capturing additional surrounding environment, as previously stated, represents a practically intentional extension of the image sensor's field of view, so that in step a) of the method of this invention, not only the vacuum component but also the surrounding environment in which the vacuum component is mounted is captured.

[0037] Analyzing the additional environmental images captured can, in particular, help to infer the intended purpose of the vacuum unit during its operation. This can be taken into account when acquiring information related to operation, in order to obtain information better suited to the operation of the vacuum unit. In particular, it can be considered that even two vacuum units of the same structural type may differ in operation, or at least the information to be displayed, if they are installed in different environments.

[0038] For example, analysis of the installation location can reveal whether the vacuum component is installed in an outdoor area, where it is exposed to the open air without protection, or at least sheltered from rain by a roof structure, or operates entirely inside a building. Simultaneously or additionally, the degree of pollution in the surrounding environment can be determined through analysis of captured images. All these characteristics constitute the framework conditions for the operation of the vacuum component, which can be considered, for example, by providing maintenance schedules appropriate to these framework conditions based on the acquired information.

[0039] The evaluation of alternative or additional installation sites may also involve: the presence of other equipment and / or building facilities, such as heating, doors, or elevators, in the surrounding environment of the vacuum component. Based on the identified objects, potential interactions or mutual influences between the vacuum component and the identified objects can be identified, such as heat input and / or vibration transmission. Here, the interaction may occur in one or both directions, i.e., from the vacuum component to the surrounding environment and / or vice versa. The corresponding analysis results can then be considered again in step d) when obtaining information concerning the operation of the vacuum component, for example, in the example above, by indicating increased cooling demand for the vacuum component when the installation site is near heating; or when additional vibration damping may be required for the vacuum component to protect sensitive balances installed in the surrounding environment of the vacuum component from interference caused by vibration transmission during vacuum pump operation.

[0040] When a high level of contamination is identified in a vacuum component, the information obtained may also include suggestions for shortening maintenance cycles or recommending particularly suitable consumables for such environments. Furthermore, requirements and / or instructions for cleaning the vacuum component may be provided, or suitable cleaning agents may be recommended, which are not necessarily required, for example, when the vacuum component is identified as being used in a cleanroom.

[0041] The identified and assessed level of contamination may alternatively or additionally identify leakage of liquid, particularly coolant or working fluid, from the vacuum component, which is especially likely to occur when the vacuum component malfunctions. The information obtained in step d) may at least include indications of the malfunction and / or related hazards to the vacuum component itself, the user, and / or the environment. Preferably, troubleshooting instructions may also be obtained as information.

[0042] Other characteristics of the surrounding environment (such as installation orientation or how the vacuum component is secured at its installation location) can also be used as criteria during analysis. For example, certain types of vacuum components should be mounted vertically only and / or require reliable securing, for example, with a sufficient number of screws. Furthermore, attention should generally be paid to the distance between the vacuum component and objects in the surrounding environment, especially the minimum distance, for example, to ensure sufficient air circulation or airflow around the vacuum component for cooling. When analyzing the surrounding environment, these or corresponding regulations can be checked against the structural type of the identified vacuum component determined in step c), and based on the results of this analysis, information obtained in step d) may indicate, for example, unfavorable orientation or defective securing of the vacuum component.

[0043] It is also possible to scan sub-components of the vacuum component in the image. Here, for the purpose of obtaining information, it may be important, for example, whether the sub-components that should be present in the identified vacuum component or the determined structural type are identifiable in the captured image, or whether they are identifiablely missing. For the identified sub-components, it is also possible to check whether they are correctly installed.

[0044] Furthermore, when analyzing the surrounding environment captured in the images, other components connected to the vacuum component can also be identified. These other components could be, for example, power supply components, such as power adapters, or gas supply or exhaust lines. Ideally, the characteristics of these identified other components should match the existing structural type of the vacuum component. In the example above, for instance, the identified power adapter should meet the requirements of the vacuum component in terms of its electrical characteristics (such as voltage, current, and / or power), and the corresponding electrical wiring should also be of sufficient size. Similarly, the gas supply or exhaust lines should have an appropriately selected diameter that matches the vacuum component, and for some vacuum components, the length of the gas supply or exhaust lines must also be considered. All these characteristics can be determined when analyzing the surrounding environment and subsequently taken into account when obtaining information in step d).

[0045] The aforementioned identification (alternatively or additionally) of the installation location of the vacuum component in its surrounding environment or the characteristics of the surrounding environment itself also includes the identification of sub-components and / or other elements connected to the vacuum component, and in particular, makes it possible to infer the intended application of the vacuum component. Depending on the intended application, different requirements may be imposed on the vacuum component, or the vacuum component may be subjected to different loads. This can also be taken into account in the information obtained in step d). For example, additional information and / or optimized application recommendations tailored to the specific application purpose can be obtained, such as recommendations for particularly suitable consumables or adjusted maintenance for the vacuum component, as information relating to the operation of the vacuum component.

[0046] According to another embodiment of the method of the present invention, it may also be specified that, in step a), additional sensors and / or data sources are manipulated to provide data and read out their data, and wherein, in step d), information is additionally acquired based on the data from the additional sensors and / or data sources read out in step a), wherein preferably at least one of the following additional sensors and / or data sources is used: - Sound sensor, - Thermal sensors, especially thermal imaging cameras, - Humidity sensor, - Temperature sensor, - Height measurement, - date, - time, - Weather data, - Location services Earthquake alert, - Solar activity.

[0047] This list is not exhaustive, and other suitable additional sensors and / or data sources may be used to further improve the acquisition of information related to the operation of vacuum components.

[0048] The additional sensors in the sense of this invention are particularly those whose measurement data goes beyond a simple picture of the vacuum chamber and its surrounding environment. Therefore, the measurement data from these additional sensors can be used to determine parameters and / or frame conditions that may affect the operation of vacuum components, especially those not previously considered. This also applies to data sources capable of providing data. Unlike sensors (which are typically directly manipulated by the evaluation unit to read their data), data sources in the sense of this invention specifically refer to, for example, query pages on the Internet.

[0049] In summary, by incorporating data from additional sensors and / or data sources when acquiring information concerning the operation of vacuum components, it is possible to take into account additional parameters and / or framework conditions that may affect operation and are not obtainable through images of the corresponding vacuum component and its surrounding environment. This allows for the acquisition of relevant information in a more specific and demand-specific manner.

[0050] For example, sound sensors and / or thermal sensors can provide direct information about the current operating status of vacuum components.

[0051] As a sound sensor, a simple microphone can be used, such as one mounted in a camera or smartphone, for example, to evaluate the audio track of a video of a vacuum component being filmed. Alternatively or additionally, a dedicated microphone or even multiple microphones can be used, the latter in particular capable of not only recording sound but also allowing for three-dimensional localization of the sound source. This, for example, makes it possible to record the operating noise of the vacuum component and, in the corresponding analysis, determine, for example, the condition of ball bearings or rolling bearings, vibration input from or entering the surrounding environment, switching processes, valve states, etc.

[0052] Thermal sensors can determine the temperature of the vacuum component, and if necessary, the temperature of the surrounding environment. This temperature measurement can be further spatially resolved by using a thermal imaging camera. Even simple thermal sensors (especially thermal imaging cameras) can display the heat distribution of the vacuum component and / or its surrounding environment, allowing for the identification of problematic or optimal temperature distributions in analysis, for example, by comparison with stored ideal values. When acquiring information in step d), this can, for example, lead to indications of overheating in certain parts of the vacuum component, or of insufficient temperature to prevent condensation in the vacuum component or other connected components (such as input or output lines).

[0053] Humidity sensors, temperature sensors, and / or sensors for altitude measurement can be used to provide parameters of the environment surrounding the vacuum component, serving as additional information for the information obtained in step d). Vacuum components typically have requirements regarding these environmental parameters; for example, operating a vacuum pump in environments with high temperatures and / or high humidity may increase the pump load. The operating parameters of a vacuum pump may also change when installed at higher altitudes, especially if the pump is designed to exhaust at atmospheric pressure. In summary, the parameters determined by these additional sensors can be at least mentioned with appropriate prompts when obtaining information in step d). Furthermore, these parameters can be proactively addressed by adjusting operating parameters (e.g., reducing the maximum permissible pumping speed, adjusting cooling power, and / or shortening maintenance intervals).

[0054] Alternatively or additionally, external data sources, particularly internet sources such as those providing date, time, weather data, location services, earthquake alerts, and / or solar activity, may be used to obtain a further data foundation for acquiring information in step d).

[0055] By incorporating dates, for example, seasonal variations in the expected weather in the surrounding environment can be included in the information acquisition in step d). Similarly, differences in the acquired information can be inferred from time, such as whether it is currently day or night.

[0056] For example, weather data such as temperature, air pressure, and / or humidity (as described above regarding temperature or humidity sensors) can be used to determine parameters of the immediate surrounding environment. Furthermore, this weather data may also include forecasts of these parameters, which in turn may affect the acquisition of information in step d).

[0057] Location services (such as GPS or similar services) can enable global positioning of vacuum components, and then determine environmental parameters for the corresponding location of the vacuum components through relevant associated data sources.

[0058] In addition, data sources such as earthquake warnings or solar activity forecasts can be used. For example, the information obtained in step d) can include instructions to place vacuum components in a safe state if it is identified that a particular vacuum component may be sensitive to such events. For example, the configuration of magnetic levitation bearings can be configured accordingly to temporarily improve system stability under vibration during an earthquake. Increased solar activity may also cause interference in the power supply network. This can be considered when obtaining information in step d) by prompting potential auxiliary components (such as energy storage devices, such as battery systems or flywheel energy storage devices) or by indicating that these auxiliary components should be preventively placed in a performance-enhanced state.

[0059] The method of the present invention may also be characterized in that, prior to step d), user identification is performed by the evaluation unit, and wherein the results of user identification are considered when acquiring information in step d). User identification can be performed by the support system itself using appropriate sensors and / or methods (e.g., facial recognition or similar methods). Alternatively or additionally, the user's corresponding input can also be considered, especially after the support system makes a corresponding request. User identification preferably provides data about the corresponding user, such as their position and / or knowledge level. Through user identification, information about who is identified in step d) can therefore be stored in the support system (especially in the evaluation unit). This makes it possible to acquire information for a specific user in step d) by considering the user identification. Preferably, for example, the knowledge level of the corresponding identified user can be considered when acquiring information, so that redundant information for the user is not output in step e).

[0060] According to another design, the method of the present invention may also specify that user identification includes authentication of the user. This authentication may be based, for example, on password input, physical and / or digital keys, and / or the user's biometrics (e.g., fingerprint or facial recognition). By taking this authentication into account, particularly when acquiring information in step d), it can be ensured that in step e), security-related information is output only to the designated group of people.

[0061] The method of the present invention can also be designed to create a digital model of the vacuum component to determine the expected course of its operation, wherein the determination of the expected course of operation is considered when acquiring information in step d). In other words, a so-called "digital twin" of the vacuum component can be created based on existing data (i.e., at least the structural type of the identified vacuum component determined from images), which can be used to simulate the operation of the vacuum component. The more data available (e.g., data about the surrounding environment and / or from other sensors and / or data sources), the more accurately the digital model can describe the expected actual course of the vacuum component's operation. By considering this prediction in step d), more accurate and realistic maintenance recommendations can be obtained, for example, when acquiring information. Furthermore, more in-depth information, such as the expected lifespan of the vacuum component, the consumption of operating and auxiliary materials (e.g., electricity, auxiliary gas, cooling water, lubricants, etc.), can be estimated more accurately with the help of the created digital model.

[0062] Furthermore, the method of the present invention may also be characterized in that the supporting system has a storage unit, and data records containing the following content are stored in the storage unit: - Images captured in step a), and / or - The vacuum components identified in step b), and / or - The structure type determined in step c), and / or - Information obtained in step d), Preferably, the data record also includes: - The surrounding environment collected in step a), and / or - The surrounding environment analysis established in step b), and / or - Data provided by other sensors and / or data sources manipulated and read in step a).

[0063] This list is not exhaustive; other suitable features may also be included in the data records and stored together.

[0064] Such stored data records (especially when they also include timestamps with the date and / or time of storage) are particularly capable of recording the execution of the method of the present invention. Preferably, this also allows for the retrospective determination of what information was output in step e) and on what basis this information was obtained in step d). Thus, fault finding can be simplified, particularly when vacuum components malfunction during subsequent operation.

[0065] Furthermore, the method of the present invention may specify that the data record also includes a timestamp, and wherein, when acquiring information in step d), at least one data record and its timestamp are compared with the current value. In other words, the time progression of the vacuum component's operation is recorded, and furthermore, when acquiring currently relevant information in step d), this time progression is considered, particularly at least one data point of this progression stored in the past. In this way, the information displayed in step e) can be better matched with the actual operation of the vacuum component, because not only the parameters that dominate at the current moment can be considered, but also previously relevant parameters. For example, faults that occurred in the past but are no longer displayed by the currently determined data can still be considered when acquiring information in step d).

[0066] In another embodiment of the method of the present invention, it may be specified that, in step d), the settable operating parameters of the vacuum component are acquired as information, and wherein, in step e), the provision of the acquired information includes setting the operating parameters of the vacuum component acquired in step d) by the output unit, wherein preferably, the evaluation unit requests user permission before setting the acquired operating parameters. The settable operating parameters are variable, particularly actively settable parameters that affect the operation of the vacuum component. For a vacuum pump, which is a vacuum component, such operating parameters may, for example, represent the rotational speed or numerical range of the pump mechanism. Other characteristics of the vacuum component (e.g., the temperature of the vacuum component to be set by internal cooling of the vacuum component, or the pressure range to be set and / or monitored by the vacuum component) may also constitute settable operating parameters in the sense of the present invention. Therefore, in step d) of the method of the present invention, acquiring such settable operating parameters as information relating to the operation of the vacuum component is particularly possible based on the identified vacuum component, and preferably based on its determined installation condition and / or the identified application type or application purpose.

[0067] In the method of the present invention, the operating parameters acquired in step d) are also provided as information in step e). In this design of the method of the present invention, this is particularly achieved by the output unit itself directly setting the operating parameters on the vacuum component. Preferably, it can be specified that the output unit has an interface through which a data communication connection with the vacuum component can be established. This data communication connection can be wired, for example, via a cable, if, for example, the output unit and the vacuum component have corresponding plug connections for the cable used. Alternatively or additionally, a wireless data communication connection can also be established, for example via WLAN, Bluetooth, or infrared, wherein in this case, the vacuum component and the output unit should have corresponding transmitting and receiving components. In summary, in this way, the acquired operating parameters can be set by the output unit itself, thereby enabling a direct and particularly rapid response to identified operating parameters to be set (especially changes in operating parameters). This allows for a safer overall design of the operation of the vacuum component.

[0068] Furthermore, in this embodiment of the method of the present invention, it may be stipulated that user permission must be requested before the output unit directly sets the aforementioned operating parameters on the vacuum component. In other words, the setting of the operating parameters by the output unit will only be executed if the user who triggered the execution of the method of the present invention agrees to the setting of the operating parameters. In this way, the setting and / or modification of operating parameters without the user's knowledge can be avoided.

[0069] According to a second aspect of the invention, this task is solved by a support system for supporting the operation of a vacuum component, the support system having at least an image sensor, an evaluation unit, and an output unit. The support system according to the second aspect of the invention is characterized in that the evaluation unit is designed to perform the method described according to the first aspect of the invention.

[0070] The support system according to the second aspect of the invention has all the elements and components required to perform the method according to the first aspect of the invention. Therefore, all the advantages and features described above with reference to the method according to the first aspect of the invention can also be provided by the support system according to the second aspect of the invention.

[0071] Furthermore, the support system of the present invention can be designed with a housing in which the image sensor, evaluation unit, and output unit are jointly arranged. In this way, the support system, at least its core components, can be provided in a single location, thereby enabling, in particular, independent and autonomous execution of the method of the present invention. Preferably, the housing is sized to allow the support system to be carried by a user. In particular, for example, the support system can be designed as or constituted by a smartphone, wherein the method is executablely stored as a corresponding computer program product in the smartphone's memory.

[0072] Alternatively, the support system of this invention may also specify that the evaluation unit consists of a computer unit spatially separated from the image sensor and output unit. The presence of at least the image sensor and output unit in the field ensures that images of the vacuum component can be captured and the acquired information output to the user. The computer unit with the evaluation unit can be located anywhere via wireless data communication. This location could, for example, be the data center of a vacuum component manufacturer, thereby enabling, for example, remote analysis and / or remote diagnostics of the vacuum component.

[0073] Furthermore, a feature of the support system of the present invention is that the output unit has an interface for transmitting data (particularly operating parameters) to the vacuum component. In this way, a data communication connection can be established between the vacuum component and the support system of the present invention. For wired data communication connections, the interface of the output unit can have a corresponding plug connection for the cable used. Alternatively or additionally, a wireless data communication connection can also be established, for example via WLAN, Bluetooth, or infrared, in which case the output unit or its interface should have corresponding transmitting and receiving components. The interface of the output unit can also be designed to support or establish multiple (particularly different) connection methods. This allows for a particularly high degree of flexibility regarding the vacuum component to which corresponding data communication connections can be established. Only an output unit interface with a USB port and additional Bluetooth transmitting / receiving components is mentioned here as an example. In summary, this allows for direct, data-based communication between the support system and the vacuum component, thereby enabling, for example, the output unit itself to set the acquired operating parameters, and thus to respond directly and particularly quickly to identified operating parameters to be set (particularly changes in operating parameters). This allows for safer design of the operation of the vacuum component.

[0074] According to a third aspect of the invention, this task is solved by a computer program product for supporting the operation of a vacuum component, wherein the computer program product contains computer-readable program code that, when executed by one or more processors of an evaluation unit of the support system according to the second aspect of the invention, causes the support system to perform the method according to the first aspect of the invention. The computer program product according to the third aspect of the invention is configured to be executed by the support system according to the second aspect of the invention, wherein the method according to the first aspect of the invention is performed. Therefore, all the advantages and features described above with reference to the method of the first aspect of the invention or the support system of the second aspect of the invention can also be provided by the computer program product according to the third aspect of the invention.

[0075] According to a fourth aspect of the invention, this task is solved by a non-transferable computer-readable medium storing a computer program product according to a third aspect of the invention. Therefore, all the advantages described above with reference to the computer program product of the third aspect of the invention, and thus also with reference to the method of the first aspect of the invention or the support system of the second aspect of the invention, can also be provided by the computer-readable medium according to the fourth aspect of the invention. Attached Figure Description

[0076] The invention will now be described by way of example with reference to the accompanying drawings. The drawings schematically illustrate the following: Figure 1 It is an image of the surrounding environment with vacuum components.

[0077] Figure 2 The method of the present invention is illustrated.

[0078] Figure 3 The supporting system of the present invention is shown. Detailed Implementation

[0079] Figure 1 An image 40 of the vacuum component 10 in its surrounding environment 22 is shown, which is during the execution of... Figure 2 In the process of the method of the present invention shown, by way of example in Figure 3 The support system 30 depicted in the image was photographed. Therefore, the following text will combine... Figure 1 , Figure 2 and Figure 3 Provide a common description, and elaborate on each diagram as necessary.

[0080] By the method of the present invention (see Figure 2 This allows the operation of the vacuum component 10 to be supported. In particular, through the method of the present invention, even users without specific training regarding the vacuum component 10, i.e., those who are not maintenance technicians or similar personnel, can display information 70 concerning the operation of the vacuum component 10 (see [link to invention]). Figure 3 Therefore, the user is also able to implement measures for the safe operation of the vacuum component 10.

[0081] The method of the present invention is executed by a support system 30, which preferably may be as follows: Figure 3 The present invention support system 30 is shown. This support system 30 includes at least an image sensor 32 for capturing an image 40 of the vacuum component 10, an output unit 36 ​​for outputting information 70, and an evaluation unit 34. The evaluation unit 34 is communicatively connected to the image sensor 32 and the output unit 36. Its function in performing the method of the present invention will be described below.

[0082] The instructions for the method of the present invention can exist in a computer-readable form as a computer program product 50 of the present invention. Preferably, the computer program product is stored on a computer-readable medium 60 of the present invention. The computer-readable medium 60 may also be part of the storage unit 62 of the supporting system 30.

[0083] like Figure 3 As shown, the aforementioned components of the support system 30 can be arranged within a common housing 80. One possible design for the support system 30 is, for example, a smartphone with a camera serving as an image sensor 32, on which a computer program product 50 containing instructions for the method of the present invention is stored and executable.

[0084] Alternatively, although not explicitly shown, in the support system 30 of the present invention, the evaluation unit 34 may also be spatially separated from the image sensor 32 and the output unit 36. Even in this case, a data communication connection still exists between the evaluation unit 34 and the image sensor 32 and the output unit 36, for example, via a wireless data connection. In this case, the user of the support system 30 only has the image sensor 32 and the output unit 36 ​​at the installation site of the vacuum component 10, while the evaluation unit 34 can be located, for example, in the data center of the vacuum component 10 manufacturer.

[0085] The method of the present invention is described below (see below). Figure 2 )about Figure 1 One possible implementation of the vacuum component 10 shown. The method of the present invention is exemplarily used in... Figure 3 This is executed under the condition that the system supports system 30.

[0086] In the first step a) A of the method of the present invention, an image 40 is captured by an image sensor 32. This image 40 can be a simple still image. Alternatively, multiple still images, preferably from different viewpoints or perspectives, or video can be used as image 40. The image 40 includes at least the vacuum components 10, which in the illustrated example are two turbopumps. Preferably, the surrounding environment 22 is also included in the image 40, as shown by a schematic view through a window opening; the surrounding environment is not limited to the area directly adjacent to the vacuum components.

[0087] Furthermore, in this first step a) A, additional sensors 38 can be read out, providing supplementary information about the surrounding environment and frame conditions in which the vacuum component 10 operates. Figure 1In the image 40, sensor 38, which determines the temperature and humidity of the environment surrounding the vacuum component 10, can be exemplarily identified. Furthermore, the support system 30 itself may also have other sensors 38 besides the image sensor 32, such as a microphone as a sound sensor or a temperature sensor. Alternatively or additionally, an external data source may be invoked in step a) A to obtain additional supplementary information. Examples include date, time, weather data, location services, earthquake alerts, or descriptions of solar activity.

[0088] In a subsequent step b) of the method of the present invention, image 40 is evaluated by evaluation unit 34 to identify vacuum component 10. In the illustrated image 40 (see...), Figure 1 As previously described, there are two such vacuum components 10. Each of these vacuum components 10 is identified in the evaluation of image 40 by evaluation unit 34. In this example, both vacuum components 10 are turbopumps.

[0089] However, simply identifying vacuum component 10 is insufficient to obtain information 70 specifically suitable for that vacuum component 10. Therefore, in another step c) C, the structural type 12 of the corresponding vacuum component 10 is determined. Thus, in this example, it is determined which type of turbopump the two vacuum components 10 identified in step b) B are.

[0090] Whether for identifying the vacuum component 10 in step b) B, or for determining the corresponding structural type 12 in step c) C, the evaluation unit 30 can evaluate the image 40 with respect to the presence of the identification feature 14. For example... Figure 1 As explicitly indicated, such identification feature 14 may be, for example, a nameplate, label, or QR code. However, in the sense of this invention, the outline or three-dimensional shape of the vacuum component 10 also constitutes identification feature 14. Furthermore, sub-components 16 of the vacuum component 10 or other elements 20 connected to the vacuum component 10 may also be used as identification feature 14, as their presence or absence or their arrangement can infer the corresponding vacuum component 10 or its structural type 12.

[0091] Based on these preparatory works, in the next step d), information 70 concerning the operation of one or more of the corresponding identified vacuum components 10 and their determined structural types 12 is obtained. This information may be, for example, an operating manual, or more in-depth information 70, such as maintenance tips or care requirements.

[0092] One advantage of this method is that the information 70 obtained is preferably not based solely on the identification of the vacuum component 10 and the determination of its structural type 12, but other decision-making criteria can also be incorporated when obtaining the information.

[0093] For example, the installation location of the vacuum component 10 can be inferred from the surrounding environment 22 captured in image 40. In the example shown, unsealed building openings and tropical vegetation in the surrounding environment 22 can be identified, from which hot and humid climatic conditions can be inferred, and further, a potentially high level of pollution can be inferred. This can be taken into account, for example, by shortening the recommended maintenance cycle or suggesting improvements to cooling in the acquired information 70.

[0094] The installation orientation of the vacuum component 10 or the distance between the vacuum component 10 and objects in the surrounding environment 22, such as walls, can also be obtained from image 40. The "inverted" installation shown here is permissible for turbopumps. Deviations from the specified installation orientation can be taken into account by the corresponding content of the acquired information 70. If the distance is identified as too small, a change in the position of the vacuum component 10 in the room can be suggested in the acquired information 70.

[0095] Furthermore, as long as they are visible in image 40, the mounting devices 18 and sub-components 16 of the vacuum components can be inspected. In this example, some screws appear to be missing from the mounting device 18 of the left vacuum component 10 visible in image 40. Also, on the left vacuum component, the mounting location identified as sub-component 16 (where the right vacuum component is supposed to have a fan installed as sub-component 16) is empty. This can be taken into account with appropriate tips and suggestions in the information 70 obtained for the left vacuum component 10.

[0096] Furthermore, the image 40 (particularly the surrounding environment 22 visible in image 40) can be used to evaluate the components 20 present and connected to the vacuum unit 10. Exemplarily, at the vacuum pump on the right, the pressure sensor and the gas supply line are labeled as other components 20. One possibility for considering these other components 20 in the acquired information is, for example, checking whether the identified components are suitable for the current vacuum unit 10 or its specific structural type 12. In this example, this can be achieved, for example, by comparing the pressure range to which the pressure sensor is applicable with the pressure range of the turbopump, or by checking whether the gas supply line is sufficient in diameter and length to meet the requirements of the current turbopump and its pumping speed.

[0097] Furthermore, as mentioned above, another sensor 38 can be manipulated, and its measurement data can also be taken into account when acquiring information in step d) D. This applies not only to the sensor 38 in the environment 22 surrounding the vacuum component 10 (see...) Figure 1This also applies to other sensors 38 supporting system 30. For example, support system 30 with a microphone as another sensor 38 can capture video with an audio track as image 40, and in addition to visual information, auditory information from the video can also be used in the method of the present invention, both for identifying vacuum component 10 in step b) B or determining structure type 12 in step c) C, and particularly for acquiring information 70 concerning the operation of vacuum component 10 in step d) D. Auditory information may, for example, include operating noise of vacuum component 10, which may make it possible to identify bearing damage.

[0098] It is also feasible to consider external data sources, and the data obtained therefrom can also be taken into account when acquiring information 70. Weather data, location services, earthquake alerts, or descriptions of solar activity are cited again as examples. For instance, if it is known that vacuum component 10 is located in an earthquake-prone area or that there is increased solar activity, it may be advantageous to take appropriate protective measures, such as installing a UPS (Uninterruptible Power Supply), and thus include them in the acquired information 70.

[0099] When acquiring information 70 in step d), user identification may also be performed, specifically including and taking into account the authentication of the corresponding user. User identification ensures that the information 70 provided is better tailored to the corresponding user (e.g., their level of knowledge). Authentication, for example, ensures that potentially security-related information 70 is only displayed to users with the appropriate security permissions.

[0100] Furthermore, it is also possible to store data related to the current vacuum component 10 and its operation, or data recorded during the execution of the method of the present invention, and the corresponding acquired information 70, in the storage unit 62. This is particularly useful for recording the method later. By additionally storing timestamps, especially when the method is executed again later, the corresponding data records can be traced back when acquiring information 70 in step d)D, thereby providing not only the timeline of the operation of the vacuum component 10, but also taking into account, especially when acquiring information 70.

[0101] In the final step e) E, the information 70 obtained in step d) D is provided through output unit 36. Figure 3 In the design of the support system 30, the information 70 is displayed visually on the output unit 36, which is designed as a screen. Alternatively or additionally, audiovisual display, such as the information 70 existing in the form of a video with background music, or physical provision, such as through a printer, may also be considered.

[0102] like Figure 3As shown, the output unit 36 ​​can also be designed with an interface 90, through which a data communication connection can be established between the monitoring system 30 and the vacuum component 10. This data communication connection can be wired and / or wireless, depending on the design of the vacuum component 10 and the interface 90. In particular, the interface 90 of the output unit 36 ​​can also be compatible with various different types of data communication connections.

[0103] This interface 90 is particularly useful when the settable operating parameters of the vacuum component 10 are acquired as information 70 in step d). These parameters can then be directly transmitted to the vacuum component 10 via a data communication connection implemented by the interface 90. Alternatively or additionally, the operating parameters can be simply displayed on the display screen of the output unit 36. In particular, it can be stipulated that the operating parameters are transmitted to the vacuum component 10 via the interface 90 only after user permission. The required user permission request can then be initiated by the support system 30, especially when displaying the operating parameters acquired as information 70.

[0104] In summary, the method of the present invention can support the operation of the vacuum component 10. In particular, by providing information 70 concerning the operation of the vacuum component 10, even users without specific training on the vacuum component 10 can be informed of measures for the safe operation of the vacuum component 10, so that these measures can be subsequently implemented.
