IEC 62657-4:20 22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: ？共存状态的确定， ？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。 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。

IEC 62657-4:2022 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.
This document is not restricted to a specific radio frequency range nor is it restricted to a specific wireless communication technology.
