摘要
针对航空/航天指挥控制系统对高可靠性及强实时性性能要求和传统订阅/发布技术的性能瓶颈缺陷,提出一种基于主题的无中心节点的新型数据交换系统。利用数据库方法和IP网络的多播技术,建立无中心服务节点的数据交换模型,设计主题订阅/发布的管理机制,实现数据的高效、实时发布。该系统高效可靠,且与操作系统平台无关,满足航空/航天指挥控制系统高实时性等任务需求,具有较好的参考价值。
Aiming at the demand of aerospace command and control system for high reliability and strong real-time performance and the performance bottleneck of traditional subscription and publication technology new data exchange system based on topic without central node is proposed.By using the database method and IP network multicast technology,the data exchange model of the uncentered service node is established,and the management mechanism of topic subscription publishing is designed to realize the efficient and real-time publishing of data.The system is efficient and reliable,independent of the operating system platform,and can meet the requirements of aerospace command and control system,such as high real-time performance,and has a good reference value.
