The work of preparing International Standards is nor

12、mally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in

13、the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepar

14、e International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that som

15、e of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13374-1 was prepared by Technical Committee ISO/TC 108, Mechanical vibration and shock, Subcommittee SC 5, Condition monitoring and diagnostics

16、 of machines. ISO 13374 consists of the following parts, under the general title Condition monitoring and diagnostics of machines Data processing, communication and presentation: Part 1: General guidelines Part 2: Data-processing requirements Part 3: Communication requirements Part 4: Presentation r

17、equirements BSISO133741:2003 vIntroduction The various computer software programs written for condition monitoring and diagnostics of machines that are currently in use cannot easily exchange data or operate in a plug-and-play fashion without an extensive integration effort. This makes it difficult

18、to integrate systems and provide a unified view of the condition of machinery to users. The intent of ISO 13374 is to provide the basic requirements for open software specifications which will allow machine condition monitoring data and information to be processed, communicated and displayed by vari

19、ous software packages without platform-specific or hardware-specific protocols. Extensible Markup Language (XML) is a project of the World Wide Web Consortium (W3C), and the development of the specification is being supervised by their XML Working Group. XML is a public format written in the Standar

20、d Generalized Markup Language (SGML) (see ISO 8879 1for details) for defining descriptions of the structures of different types of electronic documents. The version 1.0 specification was accepted by the W3C as a Recommendation in 1998. A W3C Recommendation indicates that a specification is stable, c

21、ontributes to Web interoperability, and has been reviewed by the W3C membership, who are in favour of supporting its adoption by academic, industry and research communities. It is designed to improve the functionality of the Web by providing more flexible and adaptable information identification. BS

23、tions related to data processing, communication, and presentation of machine condition monitoring and diagnostic information. NOTE Later parts of ISO 13374 (under preparation) will address specific software specification requirements for data processing, communication and presentation. 2 Data proces

24、sing 2.1 Overview Relevant data processing and analysis procedures are required to interpret the data received from condition monitoring activities. A synergistic combination of technologies should establish the cause and severity of possible faults and provide the justification for operations and m

25、aintenance actions in a pro-active manner. A data processing and information flow of the type shown in Figure 1 is recommended either on a manual or automatic basis, in order to implement condition monitoring successfully. The data flow begins at the top, where monitoring configuration data are spec

26、ified for the various sensors monitoring the equipment, and finally results in actions to be taken by maintenance and operations personnel. As the information flow progresses from data acquisition to advisory generation, data from the earlier processing blocks need to be transferred to the next proc

27、essing block and additional information acquired from or sent to external systems. Similarly, as the data evolve into information, both standard technical displays and simpler graphical presentation formats are needed. The flow progresses from data acquisition to complex prognostic tasks, ending in

28、the issuance of advisories and recommended actions (one of which may be a modification of the monitoring process itself). 2.2 Data-processing blocks 2.2.1 Machine condition assessment processing blocks Machine condition assessment can be broken into six distinct, layered processing blocks. The first

29、 three blocks are technology-specific, requiring signal processing and data analysis functions targeted to a particular technology. The following are some of the most commonly used technologies in condition monitoring and diagnostics of machines: shaft displacement monitoring; bearing vibration moni

32、d information (such as the time, calibration, data quality, data collector utilized, sensor configuration). b) Data Manipulation (DM block): performs signal analysis, computes meaningful descriptors, and derives virtual sensor readings from the raw measurements. c) State Detection (SD block): facili

33、tates the creation and maintenance of normal baseline “profiles”, searches for abnormalities whenever new data are acquired, and determines in which abnormality zone, if any, the data belong (e.g. “alert” or “alarm”). The final three blocks normally attempt to combine monitoring technologies in orde

34、r to assess the current health of the machine, predict future failures, and provide recommended action steps to operations and maintenance personnel. These three blocks and the functions they should support are as follows. d) Health Assessment (HA) block: diagnoses any faults and rates the current h

35、ealth of the equipment or process, considering all state information. e) Prognostic Assessment (PA) block: determines future health states and failure modes based on the current health assessment and projected usage loads on the equipment and/or process, as well as remaining useful life predictions.

36、 f) Advisory Generation (AG) block: provides actionable information regarding maintenance or operational changes required to optimize the life of the process and/or equipment. 2.2.2 Technical displays To facilitate analysis by qualified personnel, relevant technical displays showing data such as tre

37、nds as well as associated abnormality zones are necessary. These displays should provide the analyst with the data required to identify, confirm or understand an abnormal state. 2.2.3 Information presentation It is important that the data be converted to a form that clearly represents the informatio

38、n necessary to make corrective-action decisions. This may be done in a written format, numerically in order to demonstrate magnitudes, graphically in order to show trends, or a combination of all three. The information should include pertinent data describing the equipment or its components, the fai

39、lure type or fault, an estimate of the severity, a projection of condition and, finally, recommended action. Cost and risk factors may also be displayed. 2.2.4 External systems Retrieval of previous work histories from the maintenance system and previous operational data (starts/stops/loads) from a

40、process-data historian is important in the assessment of machinery health. After a health assessment is made, the maintenance action to be taken may range from increasing the frequency of inspection to repair or replacement of the damaged machinery or component. The effect on operations may be an ad

41、justment of operating procedures or a request to shutdown the equipment immediately. This need for rapid communication to the maintenance and operational system requires software interfaces to maintenance management systems and operational control systems. These interfaces are useful in order to com

42、municate recommended actions in the form of maintenance work requests and operational change requests. 3egaP 3002:147331OSISBBSISO133741:20033IS-47331 O1:(3002E) 4 I SO 3002 All irhgts seredevr2.2.5 Data archiving Data archiving is an important feature during all blocks of a machine condition monito

43、ring program. Previous data trends can be analysed for statistical relevance. Previous health assessments should be audited for accuracy, and root cause information added upon its discovery. 2.2.6 Block configuration Each data-processing block requires configuration information, some of which may be

44、 static information and other data may be dynamically changed by the system during operation. For example, the configuration of the Data Acquisition block may include identification of measurement monitoring locations, orientation and relative transducer position, monitoring polling rates, sensor se

45、t-up data and calibration parameters. 2.3 Conceptual information schema guidelines 2.3.1 Overview The conceptual information schema is a single integrated definition of the relative machinery and condition monitoring information, which is unbiased toward any single application of data and is indepen

46、dent of how the data are physically stored or accessed. The primary objective of the conceptual schema is to provide a consistent definition of the meanings and interrelationship of data, which can be used to integrate, share and manage the integrity of data. This information schema is a blueprint o

47、f the location of various data elements. There are various forms of information schema. The file description schema format has been used for years in the scientific programming community. It maps the format for ASCII or binary data files, which can be exported from a computer system or imported into

48、 a computer system. A complete record format description is published which specifies the data fields contained in the file, their exact location in relation to the other data fields, whether the fields are in ASCII or binary format, and the exact data format (scientific floating point, integer, cha

49、racter, varying character string) of each field. The relational information schema format is the definition language for relational database management systems. The relational method is analogous to a blue-print drawing which defines the following: various “room names” (or tables) where data will be stored; the data “contents” (or columns) in the rooms; each data columns exact data format (scientific floati
