9、 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ MARITIME NAVIGATION AND RADIOCOMMUNICATION EQUIPMENT AND SYSTEMS DIGITAL INTERFACES Part 100: Single talker and multiple listeners Extra requirements to IEC 61162-1 for the UAIS FOREWORD A PAS is a technical specification not fulfilling the requirements
10、 for a standard, but made available to the public. IEC-PAS 61162-100 has been processed by IEC technical committee 80: Maritime navigation and radiocommunication equipment and systems. The text of this PAS is based on the following document: This PAS was approved for publication by the P-members of
11、the committee concerned as indicated in the following document: Draft PASReport on voting 80/330/PAS80/338/RVD Following publication of this PAS, the technical committee or subcommittee concerned will investigate the possibility of transforming the PAS into an International Standard. This PAS docume
12、nt relates to International Standard IEC 61162-1. The document has been co- ordinated with the TC 80 Working Group preparing the AIS Standard IEC 61993 Part 2, and the NMEA Standards Committee. 1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comp
13、rising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes Internatio
14、nal Standards. 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.
15、The 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 the IEC on technical matters express, as nearly as possible, an international consen
16、sus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3)The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports o
17、r guides and they are accepted by the National Committees in that sense. 4)In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence betwe
18、en the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention
19、 is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. -,-,- 4 Copyright 2002, IEC INTRODUCTION This document is issued as a IEC Publicly Available
20、 Specification according to the IEC/PAS approval process. This agreed process allows the new information needed for the development of UAIS to be placed in the public domain in a shorter timescale than revising the appropriate International standards. This document provides information on the necess
21、ary interface standards for use with the UAIS, which are not available in the current issue of IEC 61162-1 Ed 2. The information in this PAS supersedes that in annex B (informative) of IEC 61993-2, the Standard for UAIS. This PAS will include the interface standards, which are currently being adopte
22、d in the NMEA 0183 standard and alignment will be maintained. This PAS will be replaced at a future date by, or be included within, a revision of the international standard IEC 61162-1.

23、: Single talker and multiple listeners Extra requirements to IEC 61162-1 for the UAIS 1 Scope All the requirements to effectively transmit the data of the mobile TDMA based AIS station are included in this PAS. Whilst the established Standard IEC 61162-1 sentences are available for certain functions
24、 a number of new sentences are now required to permit all specified AIS data to be transmitted. The total requirements for the AIS are included in this PAS document but the current Standard IEC 61162-1 should be referred to for the reference data applicable to the existing format. The reader should
