29、ECHANICAL DEVICES Part 19: Electronic compasses FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on

30、 all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Pu

31、blication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation.

32、 IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of

33、 opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made

34、 to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transpar

35、ently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent cert

36、ification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability sh

37、all attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including le

38、gal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this pu

39、blication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62047-19 has been prepared by subcommittee 47F: Micro

40、-electromechanical systems, of IEC technical committee 47: Semiconductor devices. The text of this standard is based on the following documents: FDIS Report on voting 47F/156/FDIS 47F/163/RVD Full information on the voting for the approval of this standard can be found in the report on voting indica

41、ted in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 62047-19 IEC:2013 5 A list of all parts in the IEC 62047 series, published under the general title Semiconductor devices Micro-electromechanical devices, can be found on the IEC website. The

42、committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised

43、edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 62047-19 IEC:2013 SEMIC

44、ONDUCTOR DEVICES MICRO-ELECTROMECHANICAL DEVICES Part 19: Electronic compasses 1 Scope This part of IEC 62047 defines terms, definitions, essential ratings and characteristics, and measuring methods of electronic compasses. This standard applies to electronic compasses composed of magnetic sensors a

45、nd acceleration sensors, or magnetic sensors alone. This standard applies to electronic compasses for mobile electronic equipment. For marine electronic compasses, see ISO 11606. Electronic compasses are called “e-compasses” for short. Types of e-compasses are: 2-axis e-compasses, 3-axis e-compasses

46、, 6-axis e-compasses, etc., all of which are covered by this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated referen

47、ces, the latest edition of the referenced document (including any amendments) applies. None 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 3-axis Helmholtz coil three Helmholtz coils that generate magnetic fields at right angles to each othe

48、r 3.2 zero magnetic field environment magnetic field environments where magnetic field strength in a space including a device under test is lower than the strength specified Note 1 to entry: The device under test (DUT) is defined in 4.1.7. 3.3 e-compass electronic compass compass that calculates and

49、 outputs an azimuth using the electrical output of sensors Note 1 to entry: The term “e-compass” is used as an abbreviated term of electronic compass. (See the above Scope.) 3.4 2-axis e-compass e-compass that uses a 2-axis magnetic sensor as a geomagnetism detection element 62047-19 IEC:2013 7 3.5 3-axis e-compass e-compass that uses a 3-axis magnetic sensor as a geomagnetism detection element 3.6 6-ax
