标准摘要
[中文适用范围]： IEC 61097的这一部分规定了GMDSS中与MF、MF/HF和VHF装置一起使用的船载DSC设备的性能要求、技术特性、操作要求和测试方法，包括1974年国际公约第四章所要求的那些要求。海上人命安全 (SOLAS) 经修订，与 IEC 60945（构成全球海上遇险和安全系统以及海上导航设备一部分的船载无线电设备）相关。本文件纳入了 IMO 决议 A.803(19)、A.804(19) 和 A.806(19)（VHF、MF 和 MF/HF 无线电装置的 DSC 设施）、IMO MSC/ Circ.862（描述求救按钮的操作）、国际电联无线电规则的规定、DSC 设备的技术特性及其使用操作程序包含在 ITU-R M.493、M.541、M. 689、M.821 和 M.1082，并考虑 IMO 决议 A.694(17) 中包含的一般要求。 ITU-R M.493-14建议书描述了A、B、D、E、H和M类DSC设备。本文件规定了适用于 SOLAS 要求的 A 类和 B 类 DSC 设备的测试程序： A 类，包括 ITU-R M.493-14 建议书附件 1、3 和 4 中定义的所有设施，并且将符合 IMO GMDSS 对 MF/HF 安装和/或 VHF 安装的运输要求； B 类，为不需要使用 A 类设备的船上设备提供最低限度的设施，并且符合 IMO GMDSS 对 MF 和/或 VHF 安装的最低运输要求。本文件还包括中频、中频/高频和甚高频装置的射频部分的要求和测试方法，在本文件的附件中规定，以供参考。注：所有文本的含义与 IMO A.803(19)、A.804(19)、A.806(19)、MSC.68(68) 决议以及 IMO 中的含义相同。 [外文原描述]： IEC 61097-3:2017 specifies the performance requirements, technical characteristics, operational requirements and methods of testing of shipborne DSC equipment for use with MF, MF/HF and VHF installations in the GMDSS, including those required by Chapter IV of the 1974 International Convention for Safety of Life at Sea (SOLAS) as amended, and is associated with IEC 60945 (Shipborne radio equipment forming part of the global maritime distress and safety system and marine navigational equipment). This document incorporates applicable parts of the performance standards of IMO Resolutions A.803(19), A.804(19) and A.806(19) (DSC facilities for VHF, MF and MF/HF radio installations), IMO MSC/Circ.862 (describing the operation of the distress button), the provisions of the ITU Radio Regulations, the technical characteristics of DSC equipment and the operational procedures for its use contained in Recommendations ITU-R M.493, M.541, M.689, M.821 and M.1082, and takes into account the general requirements contained in IMO Resolution A.694(17). This edition includes the following significant technical changes with respect to the previous edition: a) changes in the operation of DSC which have been developed by IMO and ITU since the first edition was published; b) compliance with bridge alert management (BAM); c) optional addition of remote operation of the DSC functionality. This facility can also used for type approval testing of the performance of the DSC equipment; d) incorporation of the radio frequency test methods for MF, MF/HF and VHF transceivers and watch receivers for convenience of testing.
