无线共存管理系统第4部分：管理与控制服务

[中文适用范围]： IEC 62657-4:2025 RLV 包含官方 IEC 国际标准及其红线版本。红线版本仅提供英文版，可让您快速轻松地比较官方 IEC 标准与其先前版本之间的所有更改。IEC 62657-4:2025 规定了使用无线通信进行自动化应用中央协调 (CC) 的概念和方法，以根据 IEC 62657-2 扩展共存管理。它为中央协调建立了系统元素、接口和关系。规定了用于评估和维护共存状态的功能、数据和数据交换。本文件规定了中央协调点 (CCP) 方法，作为使用 IEC 62657-3 中给出的正式描述的一个例子。本文件适用于开发、实施或修改程序或解决方案。本文件提供了自动化共存管理系统的要求。本文件规定了以下方面的要求： – 共存状态的确定， – 自动共存管理程序， – 现有无线通信解决方案的 CC 修订， – 协调传统和新无线通信系统的 CC 功能， – 用于数据交换的 CC 序列和消息格式。 本文件不限于特定的无线电频率范围，也不限于特定的无线通信技术。 与前一版本相比，此版本包括以下重大技术变化： a) 要在 CCP 与 CMWCA 和 CMWD 之间交换的数据项（参数），以确保 CCP 提供商和设备提供商之间的互操作性。 b) 现在定义了 CCP 与 CMWCA 和 CMWD 之间开展的服务序列。 当 CCP 提供商和设备提供商实施类似流程时，明确定义的序列和统一的执行规范可确保预期的互操作性。 c) 定义了要在 CCP 与 CMWCA 和 CMWD 之间交换的序列图的消息格式。通过定义消息格式、每个数据（参数）的层次结构，并由CCP提供商和设备提供商实现相同的消息格式，能够正确交换数据并确保互操作性。 [外文原描述]： IEC 62657-4:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62657-4:2025 specifies a concept and methods for central coordination (CC) of automation applications using wireless communications to extend the coexistence management according to IEC 62657-2. It establishes system elements, interfaces and relationships for a central coordination. Functions, data, and data exchange for assessing and maintaining the coexistence state are specified. This document specifies the central coordination point (CCP) approach as one example of the usage of the formal description given in IEC 62657-3. This document is applicable to develop, implement, or modify procedures or solutions. This document provides requirements for automated coexistence management systems. This document provides requirements for: – determination of the coexistence state, – automated coexistence management procedures, – CC amendments for existing wireless communication solutions, – CC functions that coordinate legacy and new wireless communication systems, – CC sequences and message formats for data exchange. This document is not restricted to a specific radio frequency range nor is it restricted to a specific wireless communication technology. This edition includes the following significant technical changes with respect to the previous edition: a) The data item (parameter) to be exchanged between CCP and CMWCA and CMWD to ensure interoperability between CCP providers and device providers. b) The sequence of services conducted between CCP and CMWCA and CMWD are now defined. When the CCP providers and the device providers implement similar process, clearly defined sequence and unified execution specifications ensure interoperability as expected. c) The message formats of sequence diagram to be exchanged between CCP and CMWCA and CMWD are defined. By defining the message formats, the hierarchical structure of each data (parameter), and implementing the same message format by the CCP provider and the device provider, enables to exchange data correctly and ensure interoperability.
