标准摘要
[中文适用范围]： IEC 61162的这一部分规定了船载导航和无线电通信设备之间以及此类系统与需要与导航和无线电通信设备通信的其他船舶系统之间的高速通信的接口要求和测试方法。本文件基于现有国际标准的适当套件的应用，为实现船载以太网上的设备之间的数据传输提供框架。本文档指定了基于以太网的总线类型网络，其中任何侦听器都可以从具有以下属性的任何发送方接收消息。 ？本文件包括根据 IEC 61162-1@ 格式化的信息多播分发的规定，例如位置定位和其他测量@，以及通用数据块（二进制文件）@ 例如在雷达和 VDR 之间传输的规定@，还包括根据 IEC 61162-3@ 格式化信息的多播分发规定，例如位置定位和其他测量。 ？本文档仅限于连接到仅由 OSI 一级或二级设备和电缆（网络基础设施）组成的单个以太网的设备（网络节点）的协议。 ？本文件仅提供设备接口的要求。通过指定 IEC 61162-1 语句@ IEC 61162-3 PGN 消息和通用二进制文件数据@ 的传输协议，这些要求将保证实施本文件的设备之间的互操作性以及设备本身的一定程度的安全行为。 ？本文件允许使用除本文件中指定的协议之外的其他协议的设备共享网络基础设施@，前提是它配备了满足 ONF 描述的要求的接口。 ？本文件包括过滤网络流量的规定，以便将每个单独设备的流量限制在可管理的水平。除了可以从各个设备要求的总和中推断出的系统要求之外，本文档不包含任何系统要求。相关标准@ IEC 61162-460@ 进一步解决了系统要求。 [外文原描述]： IEC 61162-450:2018 specifies interface requirements and methods of test for high speed communication between shipboard navigation and radiocommunication equipment as well as between such systems and other ship systems that need to communicate with navigation and radio-communication equipment. This document is based on the application of an appropriate suite of existing international standards to provide a framework for implementing data transfer between devices on a shipboard Ethernet network. This document specifies an Ethernet based bus type network where any listener can receive messages from any sender with the following properties. - This document includes provisions for multicast distribution of information formatted according to IEC 61162-1, for example position fixes and other measurements, as well as provisions for transmission of general data blocks (binary file), for example between radar and VDR, and also includes provisions for multicast distribution of information formatted according to IEC 61162-3, for example position fixes and other measurements. - This document is limited to protocols for equipment (network nodes) connected to a single Ethernet network consisting only of OSI level one or two devices and cables (Network infrastructure). - This document provides requirements only for equipment interfaces. By specifying protocols for transmission of IEC 61162-1 sentences, IEC 61162-3 PGN messages and general binary file data, these requirements will guarantee interoperability between equipment implementing this document as well as a certain level of safe behaviour of the equipment itself. - This document permits equipment using other protocols than those specified in this document to share a network infrastructure, provided that it is supplied with interfaces which satisfy the requirements described for ONF. - This document includes provisions for filtering of the network traffic in order to limit the amount of traffic to manageable level for each individual equipment. This document does not contain any system requirements other than the ones that can be inferred from the sum of individual equipment requirements. An associated standard, IEC 61162-460, further addresses system requirements. This second edition of IEC 61162-450 cancels and replaces the first edition published in 2011 and Amendment 1:2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) network traffic filtering based on IGMP snooping added; b) network traffic balancing added; c) new encapsulation of IEC 61162-3 PGNs added; d) new alternative for binary file transfer added: TCP/IP based on Annex H of IEC 62388:2007 on radars; e) general authentication tag "a:" added to support managing of cyber security risk.
