摘要
嵌入式实时系统广泛应用于通信电子、航空航天、物联网等领域。嵌入式系统的稳定性、可靠性至关重要。文中对嵌入式系统多板卡协同工作及双板卡热备份机制进行了分析,给出了多板卡协同工作及热备份系统的基本架构,介绍了热备份设计过程中涉及到的心跳机制、控制信息设计、信息同步及IP冲突检测技术等关键问题,并结合应用实例给出了多板卡协同工作及热备份系统的设计步骤和方法,通过试验验证了设计的合理性和可靠性,为基于双板卡热备份系统的设计提供了一定的参考。
Real-time embedded system is widely applied in many fields, including aerospace and aeronautics, communication and IoT（Internet of Things）.The stability and reliability of embedded system is of utmost importance. An in-depth analysis is done on the mechanism of multi-boards cooperation and the architecture of hot backup system, then heartbeat mechanism, control information, synchronization information and IP conflict detection involved in the design of hot backup system are described, and finally the simulation experiment indicates the reasonableness and reliability of the design, thus providing certain reference for the design of dual-board hot backup system.
