Design and realization of the emergency unit of video frequency switch matrix

In order to meet the lunar exploration project three follow-up mission requirements, ship-borne unified monitoring and control system for adaptive transformation, which video switch matrix as the input and output interface is not exactly the same, if the goal of horizon fault, can only replace the backup plug Box method, time-consuming effort, the task risk is too large. This paper designs a set of unified system video switch matrix emergency switch unit, which can realize the emergency signal processing of the unified system to track the link. It can effectively improve the emergency handling capability of the tracking system and reduce the task risk.
