标准摘要
[中文适用范围]： IEC 61097-7:2025 规定了符合《国际海上人命安全公约》（SOLAS）第四章要求的甚高频（VHF）无线电设备的最低性能要求、技术特性及测试方法，并规定了所需的测试结果。本文件包含了国际海事组织（IMO）决议 A.524(13) 和 MSC.511(105) 中适用的性能标准，以及国际电信联盟（ITU）建议书 ITU-R M.489-2 和 ITU-R M.493-16 中的技术特性，并考虑到与 IEC 60945 相关的 IMO 决议 A.694(17)。在适用的情况下，本文件符合国际电信联盟《无线电规则》。当本文件中的要求与 IEC 60945 中的要求不一致时，应以本文件中的要求为准。与前一版相比，本版包括以下重大技术变更：a) 文本已更新，纳入了 IMO 决议 MSC.511(105) 中新的性能标准和 ITU-R 建议书 M.493-16 中新的建议；b) 将之前在 IEC 61097-3 中规定的数字选择性呼叫条款纳入其中；c) 将之前在 IEC 61097-8 中规定的值守接收器条款纳入其中；d) 为支持 IMO 的建议，新增了第 4.3.4 条中接收信号强度指示器和第 4.6 条中软件维护的新要求；e) 为桥梁警报管理新增了附录 B 和附录 E；f) 为数字选择性呼叫新增了附录 C 和附录 D；g) 为远程控制操作新增了附录 F；h) 为设备手册新增了附录 G。 [外文原描述]： IEC 61097-7:2025 specifies the minimum performance requirements, technical characteristics and test methods with required test results for VHF radio installations capable of voice communication and digital selective calling as required by chapter IV of the International Convention for Safety of Life at Sea (SOLAS). This document incorporates the applicable part of the performance standards included in IMO Resolution A.524(13) and MSC.511(105), the technical characteristics included in Recommendation ITU-R M.489-2 and Recommendation ITU-R M.493-16, and takes account of IMO Resolution A.694(17) which is associated with IEC 60945, and conforms with the ITU Radio Regulations where applicable. When a requirement in this document is different from IEC 60945, the requirement in this document shall take precedence. 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.511(105) and new ITU-R recommendations given in M.493-16; 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 a received signal strength indicator in 4.3.4 and for software maintenance in 4.6 in support of IMO recommendations; e) new Annex B and Annex E have been added for bridge alert management; f) new Annex C and Annex D have been added for digital selective calling; g) a new Annex F has been added for remote control operation; h) a new Annex G has been added for equipment manuals.
