一种冗余式导航分发设备设计

针对多个不同体制、工作方式的电子系统协同工作、信息融合的应用需求,设计了一种冗余式导航分发设备,通过对外部多个信息源提供的时间、导航及参数信息进行信息综合处理,为电子系统内的设备提供实时、统一的导航、时间和参数信息,应用情况表明,该设备实现了整个电子系统内部各设备间us级的信息同步。通过分析信息同步需求,采用冗余架构,使用FC时间同步服务实现精确对时功能,通过双冗余FC接口实现时间、导航及参数信息的分发,并提供秒脉冲等时间基准信号,由各电子系统内部的时间处理单元实现电子系统与本设备之间的时间同步功能。

An Design of redundancy Radar navigation dispense equipment

Targeting the demand of collaborative work and information merge for military electric system with different system and working mode, proposes a design of redundancy Radar navigation dispense equipment. By comprehensive process the information provided by extern information source such as time, navigation and parameter information, provide electric system with real-time, unification navigation, time, and parameter information. The application shows that this device implements synchronization of μs level in the whole electric system. By analysis the requirement of information synchronization, using redundant architecture, this device achieved accurate timing with FC Clock synchronization service. This device dispense time, navigation and system parameter using redundant FC port, and provide time reference signal such as second pulse, the time processing unit inside all electric sub system achieved time synchronization with this device.
