摘要
航空电子系统采用重构技术提高系统的可靠性。传统的重构技术需对机载网络进行重构,重构流程复杂,系统开销大,重构时间长。本文设计一种基于数据订阅与分发技术的系统重构技术,采用静态网络动态配置的方式,简化了网络结构,提高了数据传输的灵活性。系统重构通过动态订阅与分发技术重新建立通信路由,无需重新初始化机载网络,系统重构流程简单,开销小,重构时间短。试验结果表明,采用基于数据订阅与分发技术的系统重构技术可实现不同模式下的系统重构,重构时间小于传统重构技术。
Avionics system uses reconfiguration technology to improve the reliability of the system.Traditional reconfigure technology rely on reconfiguration of airborne network. The process of reconfiguration is complex. Needs lots of resources and time. This paper designs a system reconfiguration technology based on data subscription and distribution to simplify network architecture and improve data transfer flexibility. System reconfiguration establishes a communication route through the danamic subscription and distribution technology. No needs to reinitialize the onboard network. The experimental results show that system reconfiguration technology based on data subscription and distribution can realize the system reconfiguration in different modes, and need less resources and time.
