摘　　要：根据5G通信的特点,分析应用于5G通信的自愈系统存在的问题。从数据实时性、系统可维护性和通信流量3个方面,对自愈系统装置之间的点对点连接、手拉手和经自愈开关装置转发3种通信拓扑形式进行分析,并提出了一种基于5G通信的自愈控制系统解决方案。针对自愈数据因为5G延时抖动造成的数据时效性问题对自愈逻辑的影响进行了分析,提出了采用带绝对时标的方式区分有效数据,实现多源数据同步。通过整合在线监视和运维功能,为自愈系统的发展和优化提供了新的思路和方向。最后,对所提方案在5G商用环境下进行了RTDS建模仿真验证,验证了此方案在任意自愈开关个数时可以实现百毫秒级的负荷转供。Based on the characteristics of 5G communication,the problems of self-healing systems applied to 5G communication are analyzed.From the aspects of real-time data,system maintainability,and communication traffic,this paper analyzes three communication topologies of self-healing system devices:point-to-point connections,hand-in-hand connections,and forwarding through self-healing switch devices.A self-healing control system solution based on 5G communication is proposed.An analysis was conducted on the impact of data timeliness issues caused by 5G delay jitter on self-healing logic.A method with absolute time scale was proposed to distinguish effective data and achieve multi-source data synchronization.By integrating online monitoring and operation and maintenance functions,it provides a new idea and direction for the development and optimization of self-healing system.Finally,RTDS modeling and simulation verification were conducted on the proposed scheme in a 5G commercial environment,confirming that this scheme can achieve load transfer in the hundreds of milliseconds at any number of self-healing switches.
