船舶和航海技术 船上设备和系统的船舶通信网络安装规范

[中文适用范围]： 本文件提供了船舶通信网络的安装规范，以改善船载设备之间以及独立于导航设备网络和发动机控制网络的船载系统内部的通信。本文件还可应用于使用软件和硬件来控制和监控设备和基础设施的操作技术（OT）网络，例如船舶导航设备网络和机械控制网络。本文件涵盖的船舶通信网络旨在用于信息共享，与航行安全没有直接关系。该文件利用了现有的协议相关标准，并为通信网络系统架构、管理、操作和安装等方面提供了新的规范。本文件中的新规范包括： 必要时，船载通信网络系统的冗余；不需要专家的网络管理；物理和逻辑安全；和网络安装。本文档使用标准通信网络互联网协议。本文档适用于使用 IEEE 802.3 中指定的快速以太网和千兆位以太网进行 IP 通信的船载有线网络，以及使用 IEEE 802.11 中指定的未经许可的 2.4 GHz 和 5 GHz 频段进行 IP 通信的船载无线网络。注 本文档不涵盖基于非 IP 通信的其他无线技术，例如 IEEE 802.15.1、IEEE 802.15.4 或使用 920 MHz 频段的无线通信方法。 [外文原描述]： This document provides installation specifications for ship communication networks, so as to improve communication between shipboard equipment and within shipboard systems that are independent from navigational equipment networks and engine-control networks. This document can also be applied to operational technology (OT) networks that use software and hardware to control and monitor devices and infrastructure such as navigational equipment networks and machinery control networks in ship. The ship communication networks covered in this document are intended for information sharing and are not directly related to safety of navigation. This document utilizes existing standards relating to protocols, and provides new specifications for aspects such as communication network-system architecture, administration, operation and installation. The new specifications in this document include: redundancy, if necessary, for a shipboard communication network system; a network administration that does not require experts; physical as well as logical security; and network installation. This document uses the standard communication network Internet protocol. This document applies to shipboard wired networks for IP communication, using Fast Ethernet and Gigabit Ethernet as specified in IEEE 802.3 and to shipboard wireless networks for IP communication, using the unlicensed 2,4 GHz and 5 GHz bands as specified in IEEE 802.11. NOTE Other wireless technologies based on non-IP communication such as IEEE 802.15.1, IEEE 802.15.4 or wireless communication methods using 920 MHz band are not covered in this document.
