标准摘要
[中文适用范围]： IEC 61097-9:2025 规定了适用于仅在中频波段或在中高频波段（根据国际电信联盟《无线电规则》分配给海上移动业务）运行的GMDSS系统的语音通信和数字选择性呼叫发射机和接收机的最低操作和性能要求及测试方法，并要求提供相应的测试结果。该标准依据国际海事组织决议MSC.512(105)，并考虑了国际电信联盟建议书ITU-R M.493中有关数字选择性呼叫（包括自动连接系统）的内容。本版标准取代并废止了1997年首次发布的版本，属于技术修订版。与上一版相比，本版标准在以下方面进行了重大技术更新：a) 文本已更新，加入了国际海事组织决议MSC.512(105)中规定的新的性能标准，以及国际电信联盟建议书M.493-16中的新建议；这些内容特别新增了关于接收海上安全信息和自动连接系统的要求；b) 将原本在IEC 61097-3中规定的数字选择性呼叫相关条款纳入其中；c) 将原本在IEC 61097-8中规定的值守接收机相关条款纳入其中；d) 在4.10部分增加了新的软件维护要求，以支持国际海事组织的建议；e) 增加了新的附录A、附录B和附录C，用于数字选择性呼叫；f) 增加了新的附录D和附录G，用于桥梁警报管理；g) 增加了新的附录E和附录I，用于海上安全信息；h) 增加了新的附录F，用于自动连接系统；i) 增加了新的附录H，用于设备手册；j) 增加了新的附录J，用于远程控制操作；k) 删除了原来的附录A、附录B和附录C，因为这些内容已不再相关。 [外文原描述]： IEC 61097-9:2025 specifies the minimum operational and performance requirements and test methods with required test results for transmitters and receivers capable of voice communication and digital selective calling for the GMDSS operating in either the medium frequency band only or in medium and high frequency bands allocated in the ITU Radio Regulations to the Maritime Mobile Service, as required by Chapter IV of SOLAS 1974 as amended. It is based on IMO resolution MSC.512(105) and takes account of Recommendation ITU-R M.493 for digital selective calling including the automatic connection system. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the text has been updated to incorporate the provisions of the new IMO performance standards given in Resolution MSC.512(105) and new ITU-R recommendations given in M.493-16. These provisions in particular add new requirements for reception of maritime safety information and for the automatic connection system; b) the provisions for digital selective calling which were previously in IEC 61097-3 have been incorporated; c) the provisions for watch keeping receivers which were previously in IEC 61097-8 have been incorporated; d) new requirements have been added for software maintenance in 4.10 in support of IMO recommendations; e) new Annex A, Annex B and Annex C have been added for digital selective calling; f) new Annex D and Annex G have been added for bridge alert management; g) new Annex E and Annex I have been added for maritime safety information; h) a new Annex F has been added for the automatic connection system; i) a new Annex H has been added for equipment manuals; j) a new Annex J has been added for remote control operation; k) previous Annex A, Annex B and Annex C have been deleted as they are no longer relevant.
