某机载电子控制器余度控制技术研究

Research on Residual Control Technology of an Airborne Electronic Controller

针对多电飞机对机载关键设备的高安全性、高可靠性的要求,文章对某型机载电子控制器的主备控制架构进行了研究,设计并实现了同步机制、交叉链路传输和通道切换策略,保证正常情况下主控模块工作,非主控模块处于热备份状态,发生一次故障后主备切换,二次故障后进入安全态,提升了产品的任务可靠性。

Aiming at the high safety and high reliability requirements of multi-electric aircraft for airborne key equipment,this paper studies the master-slave control architecture of a certain type of airborne electronic controller,and designs and implements the synchronization mechanism,cross-link transmission and The channel switching policy ensures that the main control module works under normal conditions.The non-master module is in the hot backup state.After a fault occurs,the active/standby switchover occurs.After the secondary fault,the security state is entered,which improves the reliability of the product.
