标准范围

IEC 62657-4:20 25规定了使用无线通信来扩展根据IEC 62657-2的共存管理的自动化应用的中央协调(CC)的概念和方法。它为中央协调建立系统元素、接口和关系。规定了用于评估和维持共存状态的功能、数据和数据交换。本文件将中央协调点（CCP）方法指定为IEC 62657-3中给出的正式描述的使用示例。本文件适用于开发、实施或修改程序或解决方案。本文档提供了自动化共存管理系统的要求。本文件提供了以下要求:-确定共存状态，-自动化共存管理程序，-CC对现有无线通信解决方案的修正，-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。本文档不限于特定的射频范围，也不限于特定的无线通信技术。与上一版相比，此版本包括以下重大技术变更:a)CCP与CMWCA和CMWD之间要交换的数据项(参数)，以确保CCP提供者和设备提供者之间的互操作性。b)现在定义了CCP与CMWCA和CMWD之间进行的服务顺序。当CCP提供商和设备提供商实现类似的过程时，明确定义的顺序和统一的执行规范确保了预期的互操作性。c)定义了CCP与CMWCA和CMWD之间要交换的序列图报文格式。通过定义消息格式、每个数据(参数)的分层结构，以及由CCP提供商和设备提供商实现相同的消息格式，能够正确地交换数据并确保互操作性。

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.
