6、The Department is further aware of the benefits to U.S.A. users of ISA standards of incorporating suitable references to the SI (and the metric system) in their business and professional dealings with other countries. Toward this end, the Department will endeavor to introduce SI-acceptable metric un

The Metric Practice Guide, which has been published by the Institute of Electrical and Electronics Engineers as ANSI/IEEE Std.268-1982, and future revisions will be the reference guide for definitions, symbols, abbreviations, and

Measurement and control

27、systems may contain thousands of devices representing functions or bits of information displayed, each potentially requiring operator actions. Considering the tremendous quantity of information confronting the operator, a high level of mental concentration is demanded.3.1.2 Psychological aspects are

28、 thought processes which are difficult to measure but which must be considered in any control center design. The importance of these aspects increases rapidly with the complexity of the process and the quantity of the control center instrumentation. Psycho-logical aspects also affect the selection a

29、nd arrangement of the display devices.3.1.3 Too often, control centers are designed without considering the principles of human engi-neering design. To the casual observer, the resulting control center may be an impressive display of lights and instruments. To the operator who must live with such a

30、presentation, it can become bewildering. Operator confusion can lead to costly operational mistakes.3.1.4 The operator can be considered a system complete with sensory inputs, data processing capability (including information storage and processing), and responsive outputs. The following sections sh

31、ow how human beings fit this information processing system analogy. This information should help the designer incorporate good human engineering concepts into the control center design.3.2 Information sensing (inputs)3.2.1 Visual inputsVisual inputs provide 80 to 90 percent of the information requir

32、ed to operate a control center. The operator interprets:1) Color, and changes of color;2) Position, and change of position (dials and switch handles);3) Patterns, and changes of pattern, e.g., on cathode ray tube (CRT) displays;4) Digital values;5) Nameplate data.3.2.2 Auditory inputsAuditory input

33、makes up the remaining 10 to 20 percent of the information required to operate a control center. This input reinforces the visual information by adding sounds from attention-getting devices such as horns, sirens, and other audible devices.3.3 Information storageMemory is the information storage unit

34、 which makes it possible to integrate previous experience with present activity. The ability to perform the jobs requirements depends on how well the operator can process the information presented and relate this to previously stored information.ISA-RP60.3-1985 153.4 Information processingThe way in

35、 which the information is presented determines the operators ability to recognize, comprehend, and react to a situation. It is evident that the operator can be overloaded with information, which leads to inefficiency and inaccuracy. The ability to recognize, comprehend, and react correctly to a situ

36、ation is usually determined by the manner and speed with which information is presented. Information theory may be used as a tool to measure the optimum combination of display type and speed to avoid the operators becoming overloaded and confused. For more information, refer to McCormick, Human Fact

37、ors Engineering, Chapter 5 (see Section 5).4 General design4.1 Objective4.1.1 This section will describe specific features and techniques that should be used in the design and layout of a control center, implementing the human engineering factors treated in Sections 2 and 3. Not all of the following

38、 recommendations will apply to every application. The designer should include only those features that are compatible with the overall design requirements of the control center and facility, taking into consideration hardware availability, cost, and delivery time.4.1.2 Information display devices in

39、clude analog indicators, recorders, indicating lights, backlighted nameplates, annunciator windows, digital displays, CRT displays, projection screens, and printers or typers. Control devices include selector switches, pushbutton switches, keyboards, and analog control stations (manual/automatic, ma

40、nual loading, setpoint, and other types).4.1.3 The use of computers to process data and generate displays should be considered where large amounts of data and/or complex operating data must be monitored and controlled. The computer can assist the operator in performing the necessary control function

41、s. A computer can operate display devices such as CRTs, indicating lights, projection screens, digital displays, analog indicators, and printers or typers.4.2 Implementation guidelines4.2.1 Equipment arrangementControl devices should be located on the control center in the same general sequence that

42、 the operator will follow in any of the operations of systems or subsystems, or located in the same relative positions that the actual equipment is located. The same concept may be applied to the location of individual sections of a control center. Consideration should also be given to prominent loc

43、ation of emergency shutdown systems.Those devices which are interrelated or are used to determine the operating condition and status of a system or subsystem may be grouped together.To assist the operator in identifying and locating a particular group of devices, space may be left between adjacent g

44、roups, different colors may be used, or groups may be outlined with tape or painted stripe.Consistent criteria should be used for the relative location of specific status conditions where multiple status display devices are used.16 ISA-RP60.3-1985Mounting the devices within graphic sections on the c

45、ontrol center can result in easier identification by the operator.Use consistent criteria for the location of nameplates in relation to their devices.Layouts for duplicate units should be identical to improve operator proficiency as long as there is proper unit identification. Arrangements utilizing

46、 reverse or mirror images in the design of control centers for duplicate units should be avoided.4.2.2 AccessibilityControl devices should be mounted on sections of the control center that are within the normal reach of the operator when the operator is in normal position, either standing or sitting

47、.Control devices should be mounted on the control center with sufficient clearance, so that the operator can conveniently operate them without interference from other devices or adjacent control center surfaces. Consideration should also be given to:1) Plant conditions that might require gloves2) Th

48、e size or strength of an operators hand3) Hindrances due to safety clothing4) Other operational hindrancesFrequently adjusted controls and often-referenced visual indicators should be located at the most convenient elevation. The height is related to the operators normal position of standing or sitt

49、ing. ISA-dRP60.7, “Control Center Construction,“ shows a typical profile, with an operators average standing or sitting line of elevation. These typical profiles are based on the physical aspects outlined in Section 2.Space should be provided for convenient storage of and access to operating checklists and instructions.4.2.3 Pattern recognitionPattern recognition and symmetry may be used to aid the operator in the detection of abnormal conditions. Mounting several edgewise indicators adjacent to each other is one way to use this technique.The direction of motion of the p
