摘　　要：民航空管系统的主备切换过程比较复杂耗时,同时管制中心之间的管制移交(AIDC)链路的选择往往需要人工进行切换,不能完全满足管制运行的需求,这会对空管的安全运行带来隐患。本文面向空管系统主备切换场景提出一种基于X.25协议判断机制的AIDC成功保证快速切换技术,利用X.25链路连接特性和AIDC数据服务要求,实现了低切换延时处理和AIDC移交成功保证。本技术在北京区管测试验证平台上进行了应用测试,并与已有的切换方案进行比较,测试结果表明,本技术在空管系统主备切换场景下优于现有的切换方案,并可应用到所有现场的空管系统主备切换中。The main and standby switching process of civil aviation air traffic control system is complex and time-consuming.At the same time,the selection of control handover(AIDC)link between control centers often needs manual switching,which can not fully meet the requirements of control operation,which will bring hidden dangers to the safe operation of air traffic control.In this paper,a fast handoff technology based on X.25 protocol judgment mechanism is proposed for active/standby handoff scenario of air traffic control system.By using X.25 link connection characteristics and AIDC data service requirements,low handoff delay processing and AIDC handover success guarantee are realized.The test results show that the technology is superior to the existing switching scheme in the active standby switching scenario of air traffic control system,and can be applied to all the active standby switching of air traffic control system.
