标准摘要
[中文适用范围]： 本部分IEC 61162规定了通过适当接口互连的海上电子仪器、导航和无线电通信设备之间数据通信的要求。 本文件旨在支持从单个讲话者到一个或多个收听者的单向串行数据传输。这些数据采用可打印ASCII形式，可以包括由批准的句子指定的任何信息或根据专有句子规则编码的信息。典型消息长度可以从11到最多79个字符，通常要求重复率高达每20毫秒一次。 本文件中的电气定义旨在适应比IEC 61162-1中规定的更高的数据速率。由于没有提供消息的保证传递和只有有限的错误检查能力，因此在所有安全应用中谨慎使用本文件非常重要。 [外文原描述]： IEC 61162-2:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61162-2:2024 edition 2.0 and the previous IEC 61162-1:1998 edition 1.0. Furthermore, comments from IEC TC 80 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 61162-2:2024 contains the requirements for data communication between maritime electronic instruments, navigation and radiocommunication equipment when interconnected via an appropriate interface. This document is intended to support one-way serial data transmission from a single talker to one or more listeners. This data is in printable ASCII form and can include any information as specified by approved sentences or information coded according to the rules for proprietary sentences. Typical messages can be from 11 to a maximum of 79 characters in length and generally require repetition rates up to once per 20 ms. The electrical definitions in this document are intended to accommodate higher data rates than are specified in IEC 61162-1. Since there is no provision for guaranteed delivery of messages and only limited error-checking capability, it is important this document is used with caution in all safety applications.
