摘　　要：首先,针对目前国内各大军民航机场语音通信交换系统的高可靠性要求,结合集中式系统架构分析了主用和备用交换服务双冗余通信设计方案的可行性;然后,从冗余协同运行的角度提出了主从倒换决策及节点分布式的同步方法和设计流程;最后,通过双冗余通信的同步测试,验证了该方法的实时性和高可靠性能。该方法与传统的双机备份通信模式相比,设计更加合理,系统部署更加便捷灵活,可作为未来军民航管制指挥领域高可靠通信应用的指导。Firstly,aiming at the high reliability requirements of voice communication and switching system in military and civil aviation airports in China,the feasibility of dual redundant communication scheme for the main and backup switching services is analyzed based on a centralized system architecture.Then,from the perspective of dual system collaborative operation,a synchronization method and design process for the switching decision of the main and backup systems and node distribution are proposed.Finally,through synchronization testing of dual redundant communication,the strong real-time and high reliability performance of the method is verified.Compared with the traditional dual standby redundant communication mode,the method has more reasonable design and more convenient and flexible system deployment.It can serve as a guide for highly reliable communication applications in future military and civil aviation control and command.
