摘 要: | 随着综合模块化航空电子系统(IMA)结构技术的发展,对航电系统的安全性和可靠性的要求也进一步提高。本文提出的IMA重构方案基于VxWorks653系统中的在线加载分区(Online-Loaded)机制,可以做到对应用程序的动态加载,使得IMA系统在发生故障时能按预设的配置进行功能迁移,从而实现IMA系统的重构。在该重构方案的基础上还同时设计了分步加载技术。测试验证表明,分步加载技术明显减少了重构的耗时,提高了重构的效率。

Design and Implementation of A Reconfiguration Blueprint Based on Online-Loaded Partition Mechanism |

Abstract: | With the further development of Integrated Modular Avionics (IMA), it requires much more security and reliability of the Avionics system. This paper proposes a reconfiguration blueprint of IMA based on the mechanism of Online-Loaded partition in VxWorks653 system. The blueprint can load applications dynamically, so that IMA system can do the function migration according to the default configuration when a failure occurs, which will implement the reconfiguration of IMA system. Based on this blueprint, this paper also designs a fractional steps loading technology, which will reduce the time of the reconfiguration obviously and improve the efficiency of the reconfiguration through testing. |
