23、IS) Part 1: AIS Base Stations Minimum operational and performance requirements, methods of testing and required test results FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Nation
24、al Committees). The object of IEC is to promote interna-tional co-operation on 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, Techni-cal Reports, Publi
25、cly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(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-governm
26、ental organiza-tions liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Or-ganization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC o
27、n technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all inter-ested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accept
28、ed by IEC National Committees in that sense. While all reasonable efforts are made 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 misinter-pretation by any end user. 4) In order to promote internation
29、al uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence be-tween any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the la
30、tter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equip-ment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its
31、 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 legal fees) and ex-penses
32、arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica-tions. 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 publication. 9) Attentio
33、n 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 62320-1 has been prepared by IEC Technical Committee 80: Mari-time navigati
34、on and radiocommunication equipment and systems. This consolidated version of IEC 62320-1 consists of the first edition (2007) documents 80/460/FDIS and 80/468/RVD and its amendment 1 (2008) documents 80/522/CDV and 80/543/RVC. The technical content is therefore identical to the base edition and its
35、 amendment and has been prepared for user convenience. It bears the edition number 1.1. A vertical line in the margin shows where the base publication has been modified by amend-ment 1. 62320-1 IEC:2007+A1:2008(E) 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
36、 A list of all parts of IEC 62320 series, under the general title: Maritime navigation and radio-communication equipment and systems Automatic Identification System (AIS) can be found on the IEC website. The committee has decided that the contents of the base publication and its amendments will rema
37、in unchanged until the maintenance result 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 edition, or amended. A bilingual version of this publication
38、 may be issued at a later date. 6 62320-1 IEC:2007+A1:2008(E) INTRODUCTION Chapter V of the International Convention for the Safety of Life at Sea 1974 (SOLAS) requires mandatory carriage of Automatic Identification System (AIS) equipment on all vessels con-structed on or after 01 July 2002. Carriag
39、e for other types and sizes of SOLAS Convention vessels was required to be completed not later than 31 December 2004. SOLAS Chapter V, Regulation 19, clause 2.4.5 states that AIS shall: 1 provide automatically to appropriate equipped shore stations, other ships and aircraft in-formation, including s
40、hips identity, type, position, course, speed, navigational status and other safety-related information; 2 receive automatically such information from similarly fitted ships; 3 monitor and track ships; and 4 exchange data with shore-based facilities. In addition, the IMO performance standards for AIS
41、 state that: The AIS should improve the safety of navigation by assisting in the efficient navigation of ships, protection of the environment, and operation of Vessel Traffic Services (VTS), by satisfying the following functional requirements: 1 in a ship-to-ship mode for collision avoidance; 2 as a
42、 means for littoral States to obtain information about a ship and its cargo; and 3 as a VTS tool, i.e. ship-to-shore (traffic management). The AIS should be capable of providing to ships and to competent authorities, information from the ship, automatically and with the required accuracy and frequen
43、cy, to facilitate ac-curate tracking. Transmission of the data should be with the minimum involvement of ships personnel and with a high level of availability. The provision of Shore Based AIS will be necessary to attain the full benefit of the SOLAS Convention requirements. This part of IEC 62320 p
44、rovides the minimum operational and performance requirements, methods of test and the required test results for AIS Base Stations. The testing is divided into three sections, the transceiver tests, the logical tests and the Presentation Interface tests. These are captured in Clauses 8, 9 and 10 resp
45、ectively. The method used for testing is that the EUT should meet all the tests requirements of Clause 8 before proceeding to Clause 9. Likewise, the unit should meet all of the test requirements before proceeding to Clause 10. Clause 10 has also been prioritised so that the tests are progressive Cl
46、auses 5 to 7 provide functional requirement information and Clause 8 provides the general test environment for the EUT. 62320-1 IEC:2007+A1:2008(E) 7 MARITIME NAVIGATION AND RADIOCOMMUNICATION EQUIPMENT AND SYSTEMS AUTOMATIC IDENTIFICATION SYSTEM (AIS) Part 1: AIS Base Stations Minimum operational a
47、nd performance requirements, methods of testing and required test results 1 Scope This part of IEC 62320 specifies the minimum operational and performance requirements, methods of testing and required test results for AIS Base Stations, compatible with the per-formance standards adopted by IMO Res.
48、MSC.74 (69), Annex 3, Universal AIS. It incorpo-rates the technical characteristics of non-shipborne, fixed station AIS equipment, included in recommendation ITU-R M.1371 and IALA Recommendation A-124. Where applicable, it also takes into account the ITU Radio Regulations. This standard takes into a
49、ccount other associ-ated IEC international standards and existing national standards, as applicable. This standard is applicable for AIS Base Stations. It does not include specifications for the display of AIS data on shore. 2 Normative references The following referenced documents are indispensable for the application of this document.
