Description

METHOD AND APPARATUS FOR PROVIDING PERMISSION-BASED ACCESS IN CASE
DATA STRUCTURES
BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The subject matter disclosed herein generally relates to remote equipment monitoring. More specifically, the subject matter relates to case data structures for use in remote equipment monitoring. More specifically, the subject matter relates to setting and changing view permissions in case data structures.
Brief Description of the Related Art
[0002] In industrial operations, industrial machines and systems are monitored to ensure proper operation and/or detect anomalies which may arise. Remote Monitoring & Diagnostic (M&D) approaches often include personnel at one location communicating with personnel at an operating site located at a separate, geographically remote location. The M&D personnel view information related to industrial machines or systems located at the operating site.
[0003] During operation, problems oftentimes occur which may warrant an operator or maintenance engineer's involvement. A case management system is created in response to an abnormality detected at an industrial machine. In many instances, M&D personnel have access to various alarming systems and supplementary contextual information that is not available to operating site engineers. This information is compiled in the case management system for review by the M&D personnel to support the investigation of the abnormality.
[0004] The created case management systems are often visible to operators at the location of the problematic industrial machine. In many instances, the case management systems have not been finalized or fully reviewed by the M&D personnel prior to the operating site operators viewing the case management system. This often leads to confusion and miscommunication among both the M&D personnel and the on-site engineers, or wasted focus by the site personnel looking at issues that aren't actually deemed important enough for them at the particular time.
[0005] The above-mentioned problems have resulted in some user dissatisfaction with previous approaches, sub-optimal application of resources in managing operations, and sub- optimal results in maintaining uptime and effective system performance. BRIEF DESCRIPTION OF THE INVENTION
[0006] The approaches described herein provide for extending case management capabilities to allow remote M&D personnel to collaborate and bind information relating to a problem in advance of conveying the information to the operating site. When the remote M&D personnel deem to escalate the case to an on-site engineer, approaches are provided for changing a permission field. This change automatically makes the case visible to the collaborating on-site engineers.
[0007] The approaches provide for the dual capability of both tracking a status of a case and using permissions to control visibility of the case. Controlling visibility allows M&D personnel to collaborate privately and without causing confusion at the operating site.
[0008] In many of these embodiments, an apparatus includes a memory device configured to store a case data structure. The case data structure is representative of characteristics of a case associated with an abnormality detected in an industrial machine or system.
[0009] The case data structure includes an evidence field with evidence. The evidence is a characteristic associated with the industrial machine or system. In some approaches, the evidence associated with the industrial machine or system is at least one of a measured temperature, a measured vibration, a measured pressured, a calculated efficiency, a structural defect, a lifespan of machine, a machine history, and a detected position shift.
[0010] The case data structure also includes an interpretation field with an interpretation.
The interpretation is a user determined condition based at least in part on the evidence. In some approaches, the interpretation is at least one of a case diagnosis, a case prognosis, a case impact, and a case urgency.
[001 1] The case data structure also includes a recommendation field with a recommendation. The recommendation is a user determined course of action to undertake with respect to the industrial machine or system based at least in part on the interpretation. In some approaches, the recommendation is at least one of: watch, wait, manual inspection, offline analysis, contact subject matter expert, contact original equipment manufacturer, change operation, invasive inspection, minor maintenance, schedule work, and shut down. [0012] The case data structure also includes a permission field with a permission. The permission field is configured to be populated with values indicative of access permissions for remote personnel at a remote site, or other users peripheral to the detailed processes around the case, such as managers. The permission field governs access to the case, but may also serve a dual-purpose, such as tracking the lifecycle status of the case, as will be discussed.
[0013] The apparatus further includes an interface with an input and an output, and a processor coupled to the interface. The processor is configured to automatically block accessibility of the case data structure at the output to the remote personnel at the remote site when the permission field is populated with a first content. The processor is further configured to automatically make the case data structure accessible at the output to the remote personnel at the remote site when the permission field is populated with a second content.
[0014] In some aspects, the input is configured to receive a command to revise one or more fields of the case data structure when the permission field is populated with the first content.
[0015] In one approach, the input is configured to receive a command to change the permission of the permission field from the first content to the second content. The received command may include, for example, a user command. In response to the input receiving the command, the processor may be configured to change the permission of the permission field from the first content to the second content.
[0016] In another aspect, a method includes storing a case data structure in a memory device. The case data structure is representative of characteristics of a case associated with an abnormality detected in an industrial machine or system,
[0017] The case data structure includes an evidence field with evidence. The evidence is a characteristic associated with the industrial machine or system. In some approaches, the evidence associated with the industrial machine or system is at least one of a measured temperature, a measured vibration, a measured pressured, a calculated efficiency, a structural defect, a lifespan of machine, a machine history, and a detected position shift.
[0018] The case data structure also includes an interpretation field with an interpretation.
The interpretation is a user determined condition based at least in part on the evidence. In some approaches, the interpretation is at least one of a case diagnosis, a case prognosis, a case impact, and a case urgency. [0019] The case data structure also includes a recommendation field with a recommendation. The recommendation is a user determined course of action to undertake with respect to the industrial machine or system based at least in part on the interpretation. In some approaches, the recommendation is at least one of: watch, wait, manual inspection, offline analysis, contact subject matter expert, contact original equipment manufacturer, change operation, invasive inspection, minor maintenance, schedule work, and shut down.
[0020] The case data structure also includes a permission field with a permission. The permission field is configured to be populated with values indicative of access permissions for remote personnel at a remote site.

DETAILED DESCRIPTION OF THE INVENTION
[0032] Referring now to FIG. 1, a system 100 for monitoring industrial machines includes an operating site 110, optionally, a data center 120, and a central monitoring center 130. The operating site 1 10 includes one or more industrial machines, equipment, or systems of industrial machines or equipment 112. Examples of industrial machines 1 12 monitored in system 100 include aircraft machinery (e.g., turbine engines), marine machinery, mining machinery, oil machinery, gas machinery, health care machinery, telecom machinery, to mention a few examples. Other examples are possible.
[0033] Industrial machine 1 12 is operably connected to a local computing device 1 14 such that the computing device 1 14 receives or obtains information from the industrial machine 112. The computing device 1 14 may be continuously connected to the industrial machine 112, or may be removably connected to the industrial machine 1 12. In one approach, the computing device 1 14 is located at the operating site 1 10. In other approaches, the computing device 114 is instead located remotely from the industrial machine 1 12.
[0034] Information received at the computing device 1 14 from the industrial machine
112 includes operational characteristics of the industrial machine 112. Operational characteristics may include a measured temperature, a measured vibration, a measured pressured, a calculated efficiency, a structural defect, a lifespan of machine, a machine history, and/or a detected position shift. Other examples are possible.
[0035] The computing device 114 may be any type of hardware device such as a personal computer, a tablet, a cellular telephone, and/or a personal digital assistant. Other examples are possible. The computing device 1 14 may include a processor, an interface (e.g., a computer based program and/or hardware) having an input (which may also include a user input) and an output, a memory, and a display device (e.g., a screen or a graphical user interface which allows for a visualization to be made). In this way, a user of the computing device 114 is able to observe information at the computing device 114 (such as operational characteristics of the industrial machine 112), input information into the computing device 1 14, send information from the computing device 1 14 to a remote device (such as at the data center 120 or the central monitoring center 130), and receive information from a remote device. The computer device 1 14 may be configured to run specific software applications, such as a historian.
[0036] The computing device 1 14 is operably connected to a data storage module 116.
The data storage module 1 16 includes a memory for short- and/or long-term storage of information received from the computing device 1 14. Examples of information received and stored at the data storage module 116 include historical information relating to the industrial machine 1 12, or information received at the computing device from a remote device (such as at the data center 120 or the central monitoring center 130).
[0037] The optional data center 120 is in communication with the operating site 1 10
(preferably, with the computing device 1 14 at the operating site) such that the data center 120 can send and/or receive information pertaining to one or more industrial machines 1 12 located at the operating site 110. The data center 120 maybe located at the operating site 1 10, at the central monitoring center 130, or in a location geographically remote from the operating site 1 10 and the central monitoring center 130. In one approach, the data center 120 is disposed on a cloud based network. [0038] The data center 120 includes one or more data storage modules 122 having corresponding memories. The data center 120 may also include one or more computing devices 124 that include a processor, an interface having an input (which may include a user input) and an output, a memory, and a display device (e.g., a screen or a graphical user interface which allows for a visualization to be made). Various applications may be performed at the data center 120, including analytic modeling, anomaly detection, and/or calculations of key performance indicators.
[0039] The central monitoring center 130 includes a computing device 132 that is in communication with the data center 120 such that the central monitoring center 130 can send and/or receive information pertaining to one or more industrial machines 112 located at the operating site 110. Alternatively, the central monitoring center 130 is in communication with the operating site 1 10 (preferably, with the computing device 114 at the operating site) such that the central monitoring center 130 can send and/or receive information pertaining to one or more industrial machines 1 12 located at the operating site 110.
[0040] In one example of the operation of the system of 100 of FIG. 1, a case data structure is stored in a memory device that may be located, for example, at the data center 120 or at the central monitoring center 130. The case data structure, discussed in greater detail elsewhere herein, represents characteristics of a case associated with an abnormality detected in an industrial machine or system 112. The case data structure includes an evidence field with evidence (e.g., a characteristic associated with the industrial machine or system), an interpretation field with an interpretation (e.g., a user determined condition based at least in part on the evidence), a recommendation field with a recommendation (e.g., a user determined course of action to undertake with respect to the industrial machine or system based at least in part on the interpretation), and a rating field.
[0041] As discussed in greater detail elsewhere herein, accessibility of the case data structure by the remote personnel at the operating site 110 is automatically blocked when the permission field is populated with a first content. The case data structure is automatically made accessible to the remote personnel at the operating site 1 10 when the permission field is populated with a second content. That is, the first content causes the blocking, while the second content provides the accessibility. Other blocking approaches are possible.
[0042] With reference now to FIG. 2, an apparatus 200 (such as computing device 132 of
FIG. 1) includes a memory device 202. The memory device 202 stores a case data structure 204 (discussed in greater detail elsewhere herein). The memory device 202 may also store one or more work data plans 206 and/or one or more prior case histories 208. A work data plan 206 includes prior maintenance performed on an industrial machine or system (such as industrial machine 1 12), as well as scheduled maintenance to be performed on an industrial machine or system in the future. A prior case history 208 includes previous case data structures 204 associated with an industrial machine or system, or with one or more classifications of industrial machines or systems.
[0043] The apparatus 200 further includes an interface 210 including an input 212
(which preferably includes a user input) and an output 214. The apparatus 200 may also include a display device 216. The apparatus 200 includes processor 218 coupled to the memory device 202, and the interface 210, and optionally, the display device 216.
[0044] When an anomaly, abnormality, or incident is detected in an industrial machine or system (such as machine 112 of FIG. 1), a case data structure 204 (or combination of case data structures 204) associated with the case is created and stored in the memory device 202. As used herein, a "case" is associated with an anomaly, an abnormality, or an incident detected in an industrial machine or system, and a "case data structure" 204 includes a data structure that represents a compilation of characteristics of the case. In one approach, the case data structure 204 is generated by personnel at the central monitoring center 130. In another approach, the case data structure 204 is generated at a local computing device (e.g., local computing device 1 14 at the operating site 110 shown in FIG. 1). In either approach, a user may link evidence, expert interpretation associated with the evidence, metadata describing the particular nature of the industrial machine at issue, and/or other relevant information such that a visual aid is created.
[0045] In many instances, it may be advantageous to restrict visibility of a case data structure 204 to M&D personnel at the central monitoring center 130. This may be appropriate, for example, at the outset of the case evaluation, when M&D personnel are assessing the case trigger (e.g., a vibration alarm that suggested an abnormality in industrial machine 112). At this early stage, M&D personnel are acquiring supplementary contextual information that may inform as to the cause of the problem. Also at this early stage, M&D personnel have not yet determined a recommendation for resolving the case. It is during this early stage of case assessment of the case data structure 204 that sharing information with on-site personnel often leads to confusion, miscommunications, and unnecessary expenditures of resources. [0046] In this regard, in one example of the apparatus 200 of FIG. 2, the case data structure 204 is provided with a permission field. The permission field is configured to be populated with values indicative of access permissions for remote personnel at a remote site. Examples of such permission values include "Private" and "Shared."
[0047] In some approaches, the permission field is a status field for storing the status of a case. In these approaches, a status of the case may have a corresponding permission value indicative of access permissions for remote personnel at a remote site. Examples of such permission values include "New Case - Private to M&D," "Not Ready," "Recommendation Ready," and "New Case to Site."
[0048] The processor 218 is configured to automatically block accessibility of the case data structure 204 at the output 214 to the remote personnel at a remote site when the permission field of the case data structure 204 is populated with a first content. The processor 218 is further configured to automatically make the case data structure 204 accessible at the output 214 to the remote personnel at the remote site when the permission field is populated with a second content.
[0049] In some approaches, the processor 218 is configured to automatically make the case data structure 204 accessible at the output 214 to the remote personnel at the remote site when the first content is removed from the permission field. In this way, the presence of the first content in the permission field acts as a barrier to remote accessibility, while the absence of the first content in the permission field allows for remote accessibility.
[0050] In some aspects, the input 212 is configured to receive a command to revise one or more fields of the case data structure 204 when the permission field is populated with the first content.
[0051] In one approach, the input 212 is configured to receive a command to change the permission of the permission field from the first content to the second content. The received command may include, for example, a user command. In response to the input 212 receiving the command, the processor 218 may be configured to change the permission of the permission field from the first content to the second content.
[0052] With reference now to FIG. 3, a case data structure 300 (such as case data structure 204 stored in memory device 202) may include an evidence field 302 with evidence. The evidence includes information associated with the anomaly and/or the industrial machine 112. For example, the evidence associated with the industrial machine or system may include: a measured temperature, a measured vibration, a measured pressured, a calculated efficiency, a structural defect, a lifespan of machine, a machine history, and/or a detected position shift. The evidence may be in the form of advisories, alarms, charts, or reports.
[0053] The case data structure 300 also includes an interpretation field 304 with one or more interpretations. The interpretation includes a user determined condition based at least in part on the evidence. For example, the interpretation may be: a case diagnosis, a case prognosis, a case impact, and/or a case urgency. The interpretation field 304 may further include an impact field 306 for storing a case impact value, and an urgency field 308 for storing a case urgency value.
[0054] The case data structure 300 also includes a recommendation field 310 with one or more recommendations. The recommendation includes a user determined course of action to undertake with respect to the industrial machine or system based at least in part on the interpretation. For example, the recommendation may be: watch, wait, manual inspection, offline analysis, contact subject matter expert, contact original equipment manufacturer, change operation, invasive inspection, minor maintenance, schedule work, and/or shut down.
[0055] The case data structure 300 also includes a permission field 318 with a permission. The permission field is configured to be populated with values indicative of access permissions for remote personnel at a remote site.
[0056] The case data structure 300 may also include a rating field 312 for storing one or more ratings. The rating field 312 may include an explanation field 314 for storing a rating explanation and/or a provider field 316 for storing a rating provider. The case data structure 300 may also include a case history field 320, and/or one or more widgets 322.
[0057] The information contained in a case data structure 300 may not only be used to assist an analyst in ascertaining a solution to the present case, but it also may be used in subsequent cases to better aid analysts in exploring resolutions which have been historically shown to be effective. Additionally, the system may be configured to automatically access past cases which may be related to the present case to assist the analyst in determining the best solution. Any information that is used in the present case may also be linked to provide additional information within the apparatus. [0058] The case data structure 300 is structured so as to allow a user to provide updates to the case, to evidence relating to the case, to their expert interpretation as to the meaning and implication of the evidence (that is, what the issue might be, and what to do about it at a particular time), and to their recommendation regarding actions to be taken. Additional abnormalities which may occur prior to or after the creation of the case data structure 300 may also be linked to the created case data structure 300. Ancillary capabilities such as collaboration, workflow with assignment/request timers, analytic escalation notifications, and other constructs can be input and stored in the case data structure 300. That is, whatever data structure is used, the case data structure 300 is easily modified.
[0059] Personnel (e.g., M&D personnel at the central monitoring center 130) review the case data structure 300 in order to provide recommendations (e.g., to the local computing device 114 at the remote operating site 1 10). In many instances, it is advantageous to restrict access (including visibility) to the case data structure 300 until the M&D personnel have had a chance to sufficiently enter relevant information, consider the relevant information, and provide a recommendation based on the relevant information.
[0060] Referring now to FIG. 4, M&D personnel may restrict access (including visibility) to a case data structure 400a by populating permission field 402a with a first content. In this example, permission field 402a is populated with a content value of "Private." In this way, only personnel with the necessary permission requirements (preferably including M&D personnel and excluding on-site engineers) may view the case data structure 400a. With the permission field 402a populated with the first content, the M&D personnel may revise one or more fields of the case data structure 400a.
[0061] Once the M&D personnel are ready to provide the case data structure 400a to the on-site engineers, the permission field 402a is populated with a second content. For example, the permission field 402b of the case data structure 400b is populated with a content value of "Shared." This may be done, for example at apparatus 200, in response to receiving a user command. In this way, personnel with the necessary permission requirements (preferably including both M&D personnel and on-site engineers) may view the case data structure 400b.
[0062] With reference now to FIG. 5, a method 500 includes storing 502 a case data structure in a memory device. The case data structure is representative of characteristics of a case associated with an abnormality detected in an industrial machine or system. [0063] The case data structure includes an evidence field with evidence. The evidence is a characteristic associated with the industrial machine or system. In some approaches, the evidence associated with the industrial machine or system is at least one of a measured temperature, a measured vibration, a measured pressured, a calculated efficiency, a structural defect, a lifespan of machine, a machine history, and a detected position shift.
[0064] The case data structure also includes an interpretation field with an interpretation.
The interpretation is a user determined condition based at least in part on the evidence. In some approaches, the interpretation is at least one of a case diagnosis, a case prognosis, a case impact, and a case urgency.
[0065] The case data structure also includes a recommendation field with a recommendation. The recommendation is a user determined course of action to undertake with respect to the industrial machine or system based at least in part on the interpretation. In some approaches, the recommendation is at least one of: watch, wait, manual inspection, offline analysis, contact subject matter expert, contact original equipment manufacturer, change operation, invasive inspection, minor maintenance, schedule work, and shut down.
[0066] The case data structure also includes a permission field with a permission. The permission field is configured to be populated with values indicative of access permissions for remote personnel at a remote site.
[0067] The method further includes automatically blocking 504 accessibility of the case data structure to the remote personnel at the remote site when the permission field is populated with a first content.
[0068] The method further includes automatically making 506 the case data structure accessible to the remote personnel at the remote site when the permission field is populated with a second content.
[0069] In one aspect, the method further includes revising one or more fields of the case data structure when the permission field is populated with the first content.
[0070] In another aspect, the method further includes receiving a command to change the permission of the permission field from the first content to the second content. The received command may include, for example, a user command. In response to receiving the command, the method further includes changing the permission of the permission field from the first content to the second content.
[0071] Preferred embodiments of this invention are described herein, including the best mode known to the inventors for carrying out the invention. It should be understood that the illustrated embodiments are exemplary only, and should not be taken as limiting the scope of the invention.
