The subject matter disclosed herein relates to inspection execution. More specifically, the subject matter disclosed herein relates to providing self-directing inspection instruction based upon discerned current inspection step, thus reducing the amount of manual intervention by an inspector or other operator.
Certain equipment and facilities, such as power generation equipment and facilities, oil and gas equipment and facilities, aircraft equipment and facilities, manufacturing equipment and facilities, and the like, include a plurality of interrelated systems, and processes. For example, power generation plants may include turbine systems and processes for operating and maintaining the turbine systems. Likewise, oil and gas operations may include carbonaceous fuel retrieval systems and processing equipment interconnected via pipelines. Similarly, aircraft systems may include airplanes and maintenance hangars useful in maintaining airworthiness and providing for maintenance support. During equipment operations, the equipment may degrade, encounter undesired conditions such as corrosion, wear and tear, and so on, potentially affecting overall equipment effectiveness. Certain inspection techniques, such as non-destructive inspection techniques or non-destructive testing (NDT) techniques, may be used to detect undesired equipment conditions.
In a conventional NDT system, data may be shared with other NDT operators or personnel using portable memory devices, paper, of through the telephone. As such, the amount of time to share data between NDT personnel may depend largely on the speed at which the physical portable memory device is physically dispatched to its target. Accordingly, it would be beneficial to improve the data sharing capabilities of the NDT system, for example, to more efficiently test and inspect a variety of systems and equipment. NDT relates to the examination of an object, material, or system without reducing future usefulness. In particular NDT inspections may be used to determine the integrity of a product using time-sensitive inspection data relating to a particular product. For example, NDT inspections may observe the “wear and tear” of a product over a particular time-period.
Many forms of NDT are currently known. For example, perhaps the most common NDT method is visual examination. During a visual examination, an inspector may, for example, simply visually inspect an object for visible imperfections. Alternatively, visual inspections may be conducted using optical technologies such as a computer-guided camera, a borescope, etc. Radiography is another form of NDT. Radiography relates to using radiation (e.g., x-rays and/or gamma rays) to detect thickness and/or density changes to a product, which may denote a defect in the product. Further, ultrasonic testing relates to transmitting high-frequency sound waves into a product to detect changes and/or imperfections to the product. Using a pulse-echo technique, sound it introduced into the product and echoes from the imperfections are returned to a receiver, signaling that the imperfection exists. Many other forms of NDT exist. For example, magnetic particle testing, penetrant testing, electromagnetic testing, leak testing, and acoustic emission testing, to name a few.
Oftentimes, product inspections may be quite complex due to the complex nature of the product being tested. For example, airplanes are very complex machines where safety and inspection standards are of the utmost importance. The Boeing 777 aircraft may have as many 3 million parts. Accordingly, a tremendous amount of time and effort is used to inspect these aircraft on a periodic basis. Further, historical data relating to previous inspections may be used to compare and contrast inspection results to understand trending data. Further, inspection data for an entire fleet of products (e.g., a fleet of Boeing 777's) may be useful for inspection purposes, as may reference materials provided by a manufacturer or other source. As may be appreciated, massive amounts of data may be gathered and used in the inspection process. This data may be pulled from many sources and may be crucial for accurate inspection.
Unfortunately, in conventional inspection systems, stepping through an inspection process may be predominantly a manual process, respondent to manual interactions from an inspector or other operator. These manual interactions may place undue burden on the inspector, limiting the number of manual processes that the inspector may complete. Accordingly, improved systems and methods for automatically directing an inspection plan are desirable.
Certain embodiments commensurate in scope with the originally claimed invention are summarized below. These embodiments are not intended to limit the scope of the claimed invention, but rather these embodiments are intended only to provide a brief summary of possible forms of the invention. Indeed, the invention may encompass a variety of forms that may be similar to or different from the embodiments set forth below.
In one embodiment, a method is provided. The method includes determining a current state within an inspection process, and determining a first portion of an inspection process that corresponds to the current state within the inspection process, wherein the inspection process comprises a plurality of steps that correspond to an inspection process. The method further includes presenting a first instructional aide associated with the first portion, and automatically presenting a second instructional aide that corresponds to a second portion of the inspection process when the current state corresponds to the second portion.
In a second embodiment, a system is provided. The system includes position detection logic, comprising machine-readable instructions, configured to identify a current location of a portion of an inspection equipment in relation to an object being inspected, and step detection logic, comprising machine-readable instructions, configured to determine a particular portion of an inspection process associated with the current location. The system further includes presentation hardware configured to present an instructional aide associated with the particular portion, and at least one processor configured to implement the position detection logic, the step detection, and control the presentation hardware, or any combination thereof.
In a third embodiment, tangible, non-transitory, machine-readable medium comprising machine-readable instructions is provided. The instructions are configured to identify a current location of a portion of an inspection equipment in relation to an object being inspected, and to determine a particular portion of an inspection process associated with the current location. The instructions are further configured to capture inspection data using the inspection equipment, and to associate an identifier of the particular portion with the inspection data.

One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.
Embodiments of the present disclosure may apply to a variety of inspection and testing techniques, including non-destructive testing (NDT) or inspection systems. In the NDT system, certain techniques such as borescopic inspection, weld inspection, remote visual inspections, x-ray inspection, ultrasonic inspection, eddy current inspection, and the like, may be used to analyze and detect a variety of conditions, including but not limited to corrosion, equipment wear and tear, cracking, leaks, and so on. The techniques described herein provide for improved NDT systems suitable for borescopic inspection, remote visual inspections, x-ray inspection, ultrasonic inspection, and/or eddy current inspection, enabling enhanced data gathering, data analysis, inspection/testing processes, and NDT collaboration techniques.
The improved NDT systems described herein may include inspection equipment using wireless conduits suitable for communicatively coupling the inspection equipment to mobile devices, such as tablets, smart phones, and augmented reality eyeglasses; to computing devices, such as notebooks, laptops, workstations, personal computers; and to “cloud” computing systems, such as cloud-based NDT ecosystems, cloud analytics, cloud-based collaboration and workflow systems, distributed computing systems, expert systems and/or knowledge-based systems. Indeed, the techniques described herein may provide for enhanced NDT data gathering, analysis, and data distribution, thus improving the detection of undesired conditions, enhancing maintenance activities, and increasing returns on investment (ROI) of facilities and equipment.
In one embodiment, a tablet may be communicatively coupled to the NDT inspection device (e.g., borescope, transportable pan-tilt-zoom camera, eddy current device, x-ray inspection device, ultrasonic inspection device), such as a MENTOR™ NDT inspection device, available from General Electric, Co., of Schenectady, N.Y., and used to provide, for example, enhanced wireless display capabilities, remote control, data analytics and/or data communications to the NDT inspection device. While other mobile devices may be used, the use of the tablet is apt, however, insofar as the tablet may provide for a larger, higher resolution display, more powerful processing cores, an increased memory, and improved battery life. Accordingly, the tablet may address certain issues, such as providing for improved visualization of data, improving the manipulatory control of the inspection device, and extending collaborative sharing to a plurality of external systems and entities.
Keeping the foregoing in mind, the present disclosure is directed towards sharing data acquired from the NDT system and/or control of applications and/or devices in the NDT system. Generally, data generated from the NDT system may be automatically distributed to various people or groups of people using techniques disclosed herein. Moreover, content displayed by an application used to monitor and/or control devices in the NDT system may be shared between individuals to create a virtual collaborative environment for monitoring and controlling the devices in the NDT system.
By way of introduction, and turning now to
In the depicted first example category of
Additionally or alternatively, the mobile device 22 may be communicatively coupled to the NDT inspection devices 12, such as the borescope 14 and/or the PTZ camera 16, through the “cloud” 24. Indeed, the mobile device 22 may use the cloud 24 computing and communications techniques (e.g., cloud-computing network), including but not limited to HTTP, HTTPS, TCP/IP, service oriented architecture (SOA) protocols (e.g., simple object access protocol [SOAP], web services description languages (WSDLs)) to interface with the NDT inspection devices 12 from any geographic location, including geographic locations remote from the physical location about to undergo inspection. Further, in one embodiment, the mobile device 22 may provide “hot spot” functionality in which mobile device 22 may provide wireless access point (WAP) functionality suitable for connecting the NDT inspection devices 12 to other systems in the cloud 24, or connected to the cloud 24, such as a computing system 29 (e.g., computer, laptop, virtual machine(s) [VM], desktop, workstation). Accordingly, collaboration may be enhanced by providing for multi-party workflows, data gathering, and data analysis.
For example, a borescope operator 26 may physically manipulate the borescope 14 at one location, while a mobile device operator 28 may use the mobile device 22 to interface with and physically manipulate the bore scope 14 at a second location through remote control techniques. The second location may be proximate to the first location, or geographically distant from the first location. Likewise, a camera operator 30 may physically operate the PTZ camera 16 at a third location, and the mobile device operator 28 may remote control PTZ camera 16 at a fourth location by using the mobile device 22. The fourth location may be proximate to the third location, or geographically distant from the third location. Any and all control actions performed by the operators 26 and 30 may be additionally performed by the operator 28 through the mobile device 22. Additionally, the operator 28 may communicate with the operators 26 and/or 30 by using the devices 14, 16, and 22 through techniques such as voice over IP (VOIP), virtual whiteboarding, text messages, and the like. By providing for remote collaboration techniques between the operator 28 operator 26, and operator 30, the techniques described herein may provide for enhanced workflows and increase resource efficiencies. Indeed, nondestructive testing processes may leverage the communicative coupling of the cloud 24 with the mobile device 22, the NDT inspection devices 12, and external systems coupled to the cloud 24.
In one mode of operation, the mobile device 22 may be operated by the bore scope operator 26 and/or the camera operator 30 to leverage, for example, a larger screen display, more powerful data processing, as well as a variety of interface techniques provided by the mobile device 22, as described in more detail below. Indeed, the mobile device 22 may be operated alongside or in tandem with the devices 14 and 16 by the respective operators 26 and 30. This enhanced flexibility provides for better utilization of resources, including human resources, and improved inspection results.
Whether controlled by the operator 28, 26, and/or 30, the borescope 14 and/or PTZ camera 16 may be used to visually inspect a wide variety of equipment and facilities. For example, the bore scope 14 may be inserted into a plurality of borescope ports and other locations of the turbomachinery 18, to provide for illumination and visual observations of a number of components of the turbomachinery 18. In the depicted embodiment, the turbo machinery 18 is illustrated as a gas turbine suitable for converting carbonaceous fuel into mechanical power. However, other equipment types may be inspected, including compressors, pumps, turbo expanders, wind turbines, hydroturbines, industrial equipment, and/or residential equipment. The turbomachinery 18 (e.g., gas turbine) may include a variety of components that may be inspected by the NDT inspection devices 12 described herein.
With the foregoing in mind, it may be beneficial to discuss certain turbomachinery 18 components that may be inspected by using the embodiments disclosed herein. For example, certain components of the turbomachinery 18 depicted in
As depicted, the turbine 54 includes three separate stages 60, 62, and 64 surrounded by a casing 76. Each stage 60, 62, and 64 includes a set of blades or buckets 66 coupled to a respective rotor wheel 68, 70, and 72, which are attached to a shaft 74. As the hot combustion gases cause rotation of turbine blades 66, the shaft 74 rotates to drive the compressor 34 and any other suitable load, such as an electrical generator. Eventually, the turbomachinery 18 diffuses and exhausts the combustion gases through an exhaust section 80. Turbine components, such as the nozzles 32, intake 38, compressor 34, vanes 46, blades 48, wheels 50, shaft 52, diffuser 56, stages 60, 62, and 64, blades 66, shaft 74, casing 76, and exhaust 80, may use the disclosed embodiments, such as the NDT inspection devices 12, to inspect and maintain said components.
Additionally, or alternatively, the PTZ camera 16 may be disposed at various locations around or inside of the turbo machinery 18, and used to procure visual observations of these locations. The PTZ camera 16 may additionally include one or more lights suitable for illuminating desired locations, and may further include zoom, pan and tilt techniques described in more detail below with respect to
Turning now to
As depicted, the eddy current inspection device 92, the ultrasonic flaw detector 94, and the digital radiography inspection device 96, may be communicatively coupled to the mobile device 22 by using wired or wireless conduits, including the conduits mentioned above with respect to
Accordingly, it may be possible to enhance the visual observation of various equipment, such as an aircraft system 104 and facilities 106, with x-ray observation modalities, ultrasonic observation modalities, and/or eddy current observation modalities. For example, the interior and the walls of pipes 108 may be inspected for corrosion and/or erosion. Likewise, obstructions or undesired growth inside of the pipes 108 may be detected by using the devices 92, 94, and/or 96. Similarly, fissures or cracks 110 disposed inside of certain ferrous or non-ferrous material 112 may be observed. Additionally, the disposition and viability of parts 114 inserted inside of a component 116 may be verified. Indeed, by using the techniques described herein, improved inspection of equipment and components 104, 108, 112 and 116 may be provided. For example, the mobile device 22 may be used to interface with and provide remote control of the devices 14, 16, 92, 94, and 96.
As depicted the borescope 14, includes an insertion tube 118 suitable for insertion into a variety of location, such as inside of the turbomachinery 18, equipment 84, pipes or conduits 86, underwater locations 88, curves or bends 90, varies locations inside or outside of the aircraft system 104, the interior of pipe 108, and so on. The insertion tube 118 may include a head end section 120, an articulating section 122, and a conduit section 124. In the depicted embodiment, the head end section 120 may include a camera 126, one or more lights 128 (e.g., LEDs), and sensors 130. As mentioned above, the borescope's camera 126 may provide images and video suitable for inspection. The lights 128 may be used to provide for illumination when the head end 120 is disposed in locations having low light or no light.
During use, the articulating section 122 may be controlled, for example, by the mobile device 22 and/or a physical joy stick 131 disposed on the borescope 14. The articulating sections 122 may steer or “bend” in various dimensions. For example, the articulation section 122 may enable movement of the head end 120 in an X-Y plane X-Z plane and/or Y-Z plane of the depicted XYZ axes 133. Indeed, the physical joystick 131 and/or the mobile device 22 may both be used alone or in combination, to provide control actions suitable for disposing the head end 120 at a variety of angles, such as the depicted angle α. In this manner, the borescope head end 120 may be positioned to visually inspect desired locations. The camera 126 may then capture, for example, a video 134, which may be displayed in a screen 135 of the borescope 14 and a screen 137 of the mobile device 22, and may be recorded by the borescope 14 and/or the mobile device 22. In one embodiment, the screens 135 and 137 may be multi-touchscreens using capacitance techniques, resistive techniques, infrared grid techniques, and the like, to detect the touch of a stylus and/or one or more human fingers. Additionally or alternatively, images and the video 134 may be transmitted into the cloud 24.
Other data, including but not limited to sensor 130 data, may additionally be communicated and/or recorded by the borescope 14. The sensor 130 data may include temperature data, distance data, clearance data (e.g., distance between a rotating and a stationary component), flow data, and so on. In certain embodiments, the borescope 14 may include a plurality of replacement tips 136. For example, the replacement tips 136 may include retrieval tips such as snares, magnetic tips, gripper tips, and the like. The replacement tips 136 may additionally include cleaning and obstruction removal tools, such as wire brushes, wire cutters, and the like. The tips 136 may additionally include tips having differing optical characteristics, such as focal length, stereoscopic views, 3-dimensional (3D) phase views, shadow views, and so on. Additionally or alternatively, the head end 120 may include a removable and replaceable head end 120. Accordingly, a plurality of head ends 120 may be provided at a variety of diameters, and the insertion tube 118 maybe disposed in a number of locations having openings from approximately one millimeter to ten millimeters or more. Indeed, a wide variety of equipment and facilities may be inspected, and the data may be shared through the mobile device 22 and/or the cloud 24.
The PTZ camera 16 may be transported to a desired location, for example, by using a shaft 142. The shaft 142 enables the camera operator 30 to move the camera and to position the camera, for example, inside of locations 86, 108, underwater 88, into hazardous (e.g., hazmat) locations, and so on. Additionally, the shaft 142 may be used to more permanently secure the PTZ camera 16 by mounting the shaft 142 onto a permanent or semi-permanent mount. In this manner, the PTZ camera 16 may be transported and/or secured at a desired location. The PTZ camera 16 may then transmit, for example by using wireless techniques, image data, video data, sensor 140 data, and the like, to the mobile device 22 and/or cloud 24. Accordingly, data received from the PTZ camera 16 may be remotely analyzed and used to determine the condition and suitability of operations for desired equipment and facilities. Indeed, the techniques described herein may provide for a comprehensive inspection and maintenance process suitable for planning, inspecting, analyzing, and/or sharing a variety of data by using the aforementioned devices 12, 14, 16, 22, 92, 94, 96, and the cloud 24, as described in more detail below with respect to
In one example, the process 150 may plan (block 152) for inspection and maintenance activities. Data acquired by using the devices 12, 14, 16, 22, 42, 44, 46, an others, such as fleet data acquired from a fleet of turbomachinery 18, from equipment users (e.g., aircraft 54 service companies), and/or equipment manufacturers, may be used to plan (block 152) maintenance and inspection activities, more efficient inspection schedules for machinery, flag certain areas for a more detailed inspection, and so on. The process 150 may then enable the use of a single mode or a multi-modal inspection (block 154) of desired facilities and equipment (e.g., turbomachinery 18). As mentioned above, the inspection (block 154) may use any one or more of the NDT inspection devices 12 (e.g., borescope 14, PTZ camera 16, eddy current inspection device 92, ultrasonic flaw detector 94, digital radiography device 96), thus providing with one or more modes of inspection (e.g., visual, ultrasonic, eddy current, x-ray). In the depicted embodiment, the mobile device 22 may be used to remote control the NDT inspection devices 12, to analyze data communicated by the NDT inspection devices 12, to provide for additional functionality not included in the NDT inspection devices 12 as described in more detail herein, to record data from the NDT inspection devices 12, and to guide the inspection (block 154), for example, by using menu-driven inspection (MDI) techniques, among others.
Results of the inspection (block 154), may then be analyzed (block 156), for example, by using the NDT device 12, by transmitting inspection data to the cloud 24, by using the mobile device 22, or a combination thereof. The analysis may include engineering analysis useful in determining remaining life for the facilities and/or equipment, wear and tear, corrosion, erosion, and so forth. The analysis may additionally include operations research (OR) analysis used to provide for more efficient parts replacement schedules, maintenance schedules, equipment utilization schedules, personnel usage schedules, new inspection schedules, and so on. The analysis (block 156) may then be reported (block 158), resulting in one or more reports 159 detailing the inspection and analysis performed and results obtained. The reports 159 may then be shared (block 160), for example, by using the cloud 24, the mobile device 22, and other techniques, such as workflow sharing techniques. In one embodiment, the process 150 may be iterative, thus, the process 150 may iterate back to planning (block 152) after the sharing (block 160) of the reports 159. By providing for embodiments useful in using the devices (e.g., 12, 14, 16, 22, 92, 94, 96) described herein to plan, inspect, analyze, report, and share data, the techniques described herein may enable a more efficient inspection and maintenance of the facilities 20, 106 and the equipment 18, 104. Indeed, the transfer of multiple categories of data may be provided, as described in more detail below with respect to
In certain modalities (e.g., visual modalities), images and video may be communicated by using certain of the NDT inspection devices 12. Other modalities may also send video, sensor data, and so on, related to or included in their respective screens. The NDT inspection device 12 may, in addition to capturing images, overlay certain data onto the image, resulting in a more informative view. For example, a borescope tip map may be overlaid on the video, showing an approximation of the disposition of a borescope tip during insertion so as to guide the operator 26 to more accurately position the borescope camera 126. The overlay tip map may include a grid having four quadrants, and the tip 136 disposition may be displayed as dot in any portion or position inside of the four quadrants. A variety of overlays may be provided, as described in more detail below, including measurement overlays, menu overlays, annotation overlays, and object identification overlays. The image and video data, such as the video 84, may then be displayed, with the overlays generally displayed on top of the image and video data.
In one embodiment, the overlays, image, and video data may be “screen scraped” from the screen 135 and communicated as screen scrapping data 166. The screen scrapping data 166 may then be displayed on the mobile device 22 and other display devices communicatively coupled to the cloud 24. Advantageously, the screen scrapping data 166 may be more easily displayed. Indeed, because pixels may include both the image or video and overlays in the same frame, the mobile device 22 may simply display the aforementioned pixels. However, providing the screen scraping data may merge both the images with the overlays, and it may be beneficial to separate the two (or more) data streams. For example, the separate data streams (e.g., image or video stream, overlay stream) may be transmitted approximately simultaneously, thus providing for faster data communications. Additionally, the data streams may be analyzed separately, thus improving data inspection and analysis.
Accordingly, in one embodiment, the image data and overlays may be separated into two or more data streams 168 and 170. The data stream 168 may include only overlays, while the data stream 170 may include images or video. In one embodiment, the images or video 170 may be synchronized with the overlays 168 by using a synchronization signal 172. For example, the synchronization signal may include timing data suitable to match a frame of the data stream 170 with one or more data items included in the overlay stream 168. In yet another embodiment, no synchronization data 172 data may be used. Instead, each frame or image 170 may include a unique ID, and this unique ID may be matched to one or more of the overlay data 168 and used to display the overlay data 168 and the image data 170 together.
The overlay data 168 may include a tip map overlay. For example, a grid having four squares (e.g., quadrant grid) may be displayed, along with a dot or circle representing a tip 136 position. This tip map may thus represent how the tip 136 is being inserted inside of an object. A first quadrant (top right) may represent the tip 136 being inserted into a top right corner looking down axially into the object, a second quadrant (top left) may represent the tip 136 being inserted into a left right corner looking down axially, a third quadrant (bottom left) may represent the tip 136 being inserted into a bottom left corner, and a fourth quadrant (bottom right) may represent the tip 136 being inserted into a bottom right corner. Accordingly, the borescope operator 26 may more easily guide insertion of the tip 136.
The overlay data 168 may also include measurement overlays. For example, measurement such as length, point to line, depth, area, multi-segment line, distance, skew, and circle gauge may be provided by enabling the user to overlay one or more cursor crosses (e.g., “+”) on top of an image. In one embodiment a stereo probe measurement tip 136, or a shadow probe measurement tip 136 may be provided, suitable for measurements inside of objects, including stereoscopic measurements and/or by projecting a shadow onto an object. By placing a plurality of cursor icons (e.g., cursor crosses) over an image, the measurements may be derived using stereoscopic techniques. For example, placing two cursors icons may provide for a linear point-to-point measurement (e.g., length). Placing three cursor icons may provide for a perpendicular distance from a point to a line (e.g., point to line). Placing four cursor icons may provide for a perpendicular distance between a surface (derived by using three cursors) and a point (the fourth cursor) above or below the surface (e.g., depth). Placing three or more cursors around a feature or defect may then give an approximate area of the surface contained inside the cursors. Placing three or more cursors may also enable a length of a multi-segment line following each cursor.
Likewise, by projecting a shadow, the measurements may be derived based on illumination and resulting shadows. Accordingly, by positioning the shadow across the measurement area, then placing two cursors as close as possible to the shadow at furthermost points of a desired measurement may result in the derivation of the distance between the points. Placing the shadow across the measurement area, and then placing cursors at edges (e.g., illuminated edges) of the desired measurement area approximately to the center of a horizontal shadow may result in a skew measurement, otherwise defined as a linear (point-to-point) measurement on a surface that is not perpendicular to the probe 14 view. This may be useful when a vertical shadow is not obtainable.
Similarly, positioning a shadow across the measurement area, and then placing one cursor on a raised surface and a second cursor on a recessed surface may result in the derivation of depth, or a distance between a surface and a point above or below the surface. Positioning the shadow near the measurement area, and then placing a circle (e.g., circle cursor of user selectable diameter, also referred to as circle gauge) close to the shadow and over a defect may then derive the approximate diameter, circumference, and/or area of the defect.
Overlay data 168 may also include annotation data. For example, text and graphics (e.g. arrow pointers, crosses, geometric shapes) may be overlaid on top of an image to annotate certain features, such as “surface crack.” Additionally, audio may be captured by the NDT inspection device 12, and provided as an audio overlay. For example, a voice annotation, sounds of the equipment undergoing inspection, and so on, may be overlaid on an image or video as audio. The overlay data 168 received by the mobile device 22 and/or cloud 24 may then be rendered by a variety of techniques. For example, HTML5 or other markup languages may be used to display the overlay data 168. In one embodiment, the mobile device 22 and/or cloud 24 may provide for a first user interface different from a second user interface provided by the NDT device 12. Accordingly, the overlay data 168 may be simplified and only send basic information. For example, in the case of the tip map, the overlay data 168 may simply include X and Y data correlative to the location of the tip, and the first user interface may then use the X and Y data to visually display the tip on a grid.
Additionally sensor data 174 may be communicated. For example, data from the sensors 126, 140, and x-ray sensor data, eddy current sensor data, and the like may be communicated. In certain embodiments, the sensor data 174 may be synchronized with the overlay data 168, for example, overlay tip maps may be displayed alongside with temperature information, pressure information, flow information, clearance, and so on. Likewise, the sensor data 174 may be displayed alongside the image or video data 170.
In certain embodiments, force feedback or haptic feedback data 176 may be communicated. The force feedback data 176 may include, for example, data related to the borescope 14 tip 136 abutting or contacting against a structure, vibrations felt by the tip 136 or vibration sensors 126, force related to flows, temperatures, clearances, pressures, and the like. The mobile device 22 may include, for example, a tactile layer having fluid-filled microchannels, which, based on the force feedback data 176, may alter fluid pressure and/or redirect fluid in response. Indeed, the techniques describe herein, may provide for responses actuated by the mobile device 22 suitable for representing sensor data 174 and other data in the conduit 162 as tactile forces.
The NDT devices 12 may additionally communicate position data 178. For example, the position data 178 may include locations of the NDT devices 12 in relation to equipment 18, 104, and/or facilities 20, 106. For example, techniques such as indoor GPS, RFID, triangulation (e.g., WiFi triangulation, radio triangulation) may be used to determine the position 178 of the devices 12. Object data 180 may include data related to the object under inspection. For example, the object data 180 may include identifying information (e.g., serial numbers), observations on equipment condition, annotations (textual annotations, voice annotations), and so on. Other types of data 182 may be used, including but not limited to menu-driven inspection data, which when used, provides a set of pre-defined “tags” that can be applied as text annotations and metadata. These tags may include location information (e.g., 1st stage HP compressor) or indications (e.g., foreign object damage) related to the object undergoing inspection. Other data 182 may additionally include remote file system data, in which the mobile device 22 may view and manipulate files and file constructs (e.g., folders, subfolders) of data located in the memory 25 of the NDT inspection device 12. Accordingly, files may be transferred to the mobile device 22 and cloud 24, edited and transferred back into the memory 25. By communicating the data 164-182 to the mobile device 22 and the cloud 24, the techniques described herein may enable a faster and more efficient process 150.
As previously discussed, it may be beneficial to provide self-directing guidance of an inspection process to an inspector. For example, in some embodiments, inspection equipment may provide Menu Driven Inspection (MDI) or an on device application, which may guide an inspector or other operator through the inspection process by providing instructions and/or other supplemental data relating to a current step of the inspection process. By enabling this guidance to be self-directing, less manual interaction may be needed, freeing an inspector to complete alternative tasks. As will be discussed in more detail below, the self-directing inspection instructions may be enabled through determining applicable instructions based upon location awareness of at least a portion of the inspection equipment.
Once the inspection steps have been received, the current inspection step is presented to the inspector or other operator (block 304). For example, a display of the inspection equipment may provide a graphical or textual-based indication of the current inspection step. In some embodiments, when an inspection plan is first initiated, the inspection equipment may assume that information regarding the first inspection step is the currently applicable information. In some embodiments, this may be verified or determined based upon step detection logic, which will be described in more detail below.
The device may then monitor for an indication of the completion of the current inspection step and/or that a next step is ready to be implemented (block 306). Until such an indication is present, the displayed current inspection step may remain constant. However, when such an indication is present, a determination may be made regarding whether there are additional steps (decision block 308). When no additional steps are available, the process 300 ends (block 310). However, when there are additional steps, the next inspection step is displayed (block 312). This inspection step remains displayed until it is determined that the step is complete (block 306). This process 300 continues until the process completes or an inspector or other operator cancels or concludes the process.
Further, the inspection equipment 330 may include a processor 336, which may control and/or execute processes of the inspection equipment 330. For example, the processor may execute applications 338 on the inspection equipment 330, may interpret user controls 340, such as buttons and/or knobs, to effect a change in the inspection equipment, and may control the presentation of images and/or text on a display 342 (e.g., MDI instructions for one or more particular steps).
The processor 336 may determine a current step of the inspection plan using step detection logic 342. The step detection logic may be circuitry and/or machine-readable instructions implementable by the processor 336. In some embodiments, the step detection logic may make use of position detection logic 344 which may, for example, determine a location of a portion of the inspection equipment 330. For example, if the inspection equipment includes a probe for gathering inspection data, the position detection logic 344 may determine the probe's location, which may be used by the step detection logic 342 to determine a currently applicable step of the inspection plan. While the current embodiment shows the step detection logic 342 and the position detection logic implemented as part of the inspection equipment 300, in alternative embodiments, the one or more of these pieces of logic 342 and 344 may be implemented separate from the inspection equipment 330. For example, the step detection logic 342 may be provided by the service provider 334 either separate from or included in the inspection steps 336. Further, the position detection logic 344 may be provided in a remote device, such as in a probe or other collection device, communicatively coupled with the inspection equipment 330.
Based upon determining the currently applicable step from the set of inspection steps 336, the processor 336 may present applicable instructions. For example, the processor may present graphical and/or textual based instructions related to the currently applicable step on the display 342. In some embodiments, audible instructions may be provided via a speaker 346. These visual and/or audible instructions may provide guidance to the inspector or other operator reducing manual intervention of an inspector. For example, in conventional systems where an inspection might need to step through the instructions using an arrow key user control 340, the inspector's dexterity may be reduced. By implementing the self-directed inspection process, the inspector's hands may be used for other processes, improving the inspector's dexterity.
As illustrated in
In the current example, the inspection plan 384 includes 5 steps: (1) calibration, (2) positioning, and (3-5) image captures. Based upon the application 386 provided to the borescope 372, instructional aide may be presented. In the current example, the calibrate instructional aide 388 is presented on the display 342. The instructional aide 388 may include images and/or video 390 as well as text 392.
The step detection logic may use many factors in determining the currently applicable step. For example, a position of a portion of the borescope 372, such as the camera tip 378 may be useful in determining an applicable step. The location may be determined by position location logic, which may reference, for example, global positioning system signals, radio frequency identification (RFID) location signals, image identification signals, such as barcode location identifiers, or image recognition logic that may determine an inspection location based upon interpreting a captured image. Further, other measureable operational attributes of the borescope may be used to discern the location, and thus, the currently applicable step. For instance, an orientation of a portion of the borescope 374, such as the insertion tube 374 or the camera tip 378 or an exposed length of the insertion tube 374 or distance of the camera tip 378 from the retractable opening 396 may be useful in discerning the location.
In the current example, the calibration step (step 1) may be discerned as the currently applicable step when the insertion tube is fully retracted into the retractable opening 396, when an operator attempts to access specific user controls 340, when the distance between the borescope 372 and the camera tip 378 is minimal, and/or when the application 386 is initialized on the borescope 372. As these attributes change (e.g., the distance between the tip 378 and the borescope 372 increase, the insertion tube protracts, and/or the position and/or orientation of the camera tip 378 changes), the borescope 372 may discern that the calibration step (step 1) is complete. Accordingly, the display 342 may present any transitional instructional aides until it is discerned that the currently applicable step is step 2, as illustrated by the progression icon 398. For example, the step detection logic 342 may define that step 2 is the currently applicable step when the length “L1” 400 is reached, when the tip 378 reaches the insertion port 382, when the distance between the tip 378 and the retractable opening 396 is length “L1” 400, etc. Upon satisfying the definition for discerning step 2 as the currently applicable step, the step 2 aide is presented, as illustrated by the progression icon 404. The step detection logic may discern a transition from step 2 to step 3 upon passing the satisfying definition. For example, passing the distance between “L1” 400 between the retractable opening 396 and the tip 378 and/or passing the length “l1” 400 of the protracted insertion tube 374 defining that step 2 is the currently applicable step. During this transition, transitional aides may be provided, as indicated by the progression icon 406.
Once the definitions used to discern step 3 as the currently applicable step are met, the step 3 instructional aides may be presented, as illustrated by the progression icon 408. For example, as indicated by the orientation icon 410, one defining characteristic may be a particular angle of the insertion tube 374 and/or the camera tip 378. Further, a defining characteristic may include reaching length “L1” 400+“L2” 412, either as a length of the protracted insertion tube 374 and/or the distance between the camera tip 378 and the retraction opening 396.
As illustrated above, a number of factors may be used to discern the currently applicable step. In some embodiments, the captured data may be useful to discern when a step is completed and thus a transition to the next step is likely. For example, upon collecting the image data defined by step 3, the inspection equipment may discern a transition to step 4 until the step 4 criteria is met. Accordingly, a transitional aide may be provided, as illustrated by the progression icon 414.
In the current example, criteria to discern step 4 as the currently applicable step may include a changed orientation of the insertion tube 374 and/or tip 378, as indicated by the orientation icon 416. Further the criteria may include image recognition of a particular location within the object of inspection, as indicated by the image recognition icon 418. The criteria may include a condition of the tip reaching the location 420 of step 4 and/or the length “L1” 400+length “L2” 412+length “L3” 422 being reached either by the protracted insertion tube 374 length and/or the distance of the tip 378 from the retraction opening 396. When the criteria is met, the instructional aide for step 4 may be presented, as illustrated by the progression icon 424.
During transition, to the next step, transitional aides may be presented if available (as illustrated by icon 426). Upon reaching the criteria for step 5, which may include an orientation criteria, as illustrated by the orientation icon 428, a location 430 criteria, and/or a length criteria that include length “L4” 432, the step 5 instructional aide may be presented, as illustrated by progression icon 434. Upon completion of step 5, a completed inspection notification may optionally be provided, as illustrated by progression icon 436, indicating that the inspection is complete and presenting additional information, such as the next inspection on the inspector's agenda, etc.
As may be appreciated, by utilizing a self-directed inspection plan that automatically proceeds to display instructions relating to a particular inspection step when it is determined that these instructions apply, the burden of manual interaction by an inspector or other operator may be reduced. Accordingly, the inspector or other operator may complete additional inspection related tasks based upon hands-free operation of the automatic self-directing inspection plan. Further, as data is captured, location information may be automatically “tagged” with inspection location information, which may provide further context for captured inspection data.
