海上导航和无线电通信设备及系统 数字接口 第1部分：单讲话者和多听众

[中文适用范围]： IEC 61162的这一部分包含了通过适当系统互连时，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。本文档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的ASCII形式，可能包括位置、速度、深度、频率分配等信息。典型消息长度约为11到最多79个字符，一般传输速度不超过每秒一条消息。本文档中的电气定义不适用于高带宽应用，如雷达或视频图像，或密集数据库或文件传输应用。由于没有提供消息的保证传递和有限的错误检查能力，因此在所有安全应用中应谨慎使用本文档。对于需要更快传输速率的应用，应参考IEC 61162-2。对于岸基自动识别系统（AIS）设备的应用，应参考IEC 62320系列。 [外文原描述]： IEC 61162-1:2024 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 61162-1:2024 edition 6.0 and the previous IEC 61162-1:2016 edition 5.0. 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 61162-1:2024 contains the requirements for data communication between maritime electronic instruments, navigation and radiocommunication equipment when interconnected via an appropriate system. This document is intended to support one-way serial data transmission from a single talker to one or more listeners. These data are in printable ASCII form and can include information such as position, speed, depth, frequency allocation, etc. Typical messages can be from about 11 to a maximum of 79 characters in length and generally require transmission no more rapidly than one message per second. The electrical definitions in this document are not intended to accommodate high-bandwidth applications such as radar or video imagery, or intensive database or file transfer applications. 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. For applications where a faster transmission rate is necessary, IEC 61162-2 applies. For applications to shore based equipment of the automatic identification system (AIS) the IEC 62320 series applies.
