摘　　要：目前,民航管制单位在与相邻管制单位进行AIDC移交时,如果采用的是X.25专线方式,则需要在本地2套自动化系统之间共享一条物理链路。当自动化系统主备状态切换时,往往需要人工方式切换线缆连接,切换时间较长且增加了故障风险。提出了一种串口切换设备的设计方案,使2套自动化系统的X.25处理设备能够以切换的方式共享一条专线链路,并且支持3种切换模式。目前切换器样机已在北京区管测试平台上进行了功能测试,在主备自动化系统AIDC链路切换场景下能够实现物理链路的快速切换。At present,the AIDC interconnection is based on the X.25 line between the civil aviation control units,and the physical line needs to be shared between main and standby automation systems.When the automation system state is switched,it is often necessary to manually switch cable connections.This increases switching time and increases the risk of failure.In this paper,a serial switcher design is proposed,so that the X.25 processing equipment of 2 sets of automation system can share a physical link by switching,and supports three switching modes.At present,the switcher prototype has been tested on the Beijing ACC test platform,and the rapid switching of physical links can be realized in the scenario of AIDC link switching of the automation systems.
