Abstract： 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.
