海上导航和无线电通信设备及系统. 数字接口. 第1部分: 单通话器和多方收听器

[中文适用范围]： IEC 61162 的这一部分包含了通过适当的系统互连时海事电子仪器、导航和无线电通信设备之间的数据通信的要求。 IEC 61162 的这一部分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。典型的消息长度可能约为 11 到最多 79 个字符，并且通常要求传输速度不超过每条消息一条。第二。本标准中的电气定义并非旨在适应雷达或视频图像等高带宽应用，或密集型数据库或文件传输应用。由于没有提供保证消息传递的规定，并且只有有限的错误检查能力，因此在所有安全应用中应谨慎使用该标准。对于需要更快传输速率的应用，应参考 IEC 61162-2。对于自动识别系统 (AIS) 岸基设备的应用，应参考 IEC 62320 系列。 [外文原描述]： IEC 61162-1:2016 contains the requirements for data communication between maritime electronic instruments, navigation and radiocommunication equipment when interconnected via an appropriate system. This part of IEC 61162 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 may include information such as position, speed, depth, frequency allocation, etc. Typical messages may 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 standard 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, this standard should be used with caution in all safety applications. For applications where a faster transmission rate is necessary, reference should be made to IEC 61162-2. For applications to shore based equipment of the automatic identification system (AIS) reference should be made to the IEC 62320 series. This fifth edition cancels and replaces the fourth edition published in 2010, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - new identifiers have been added to Table 4; - the sentences CBR and MEB have been removed as they are now solely used by AIS shore based equipment; - new sentences ACN, ALC, ALF, ARC, EPV, HCR, HRM, MOB, NSR, RLM, RRT, SM1, SM2, SM3, SM4, SMB, SPW and TRL have been added; - revisions have been made to ABK, ABM, GNS, NAK, NRM, RMC, ROR and TTD; - the methods of testing in Annex B have been revised.
