双冗余热备份技术的综合控制设备设计与实现

Design and Realization of Synthetic Control Equipment Based on Dual Hot Redundancy Technology

为提高地面装备可靠性,提出一种基于双冗余热备份技术的车载综合控制设备,采用仲裁方式实现状态实时监测及主、备切换功能,同时基于复杂度、可靠性及实现难度考虑,设计一种任务级同步的余度管理方法,通过余度间的通信链路及运行在CPU模块上的任务同步软件模块实现主、备间的任务同步,既满足设备同步需求,同时易于实现,复杂度低。

To improve system reliability,a synthetic control equipment with dual CPU hot-redundancy technology is proposed,in which the real time state monitor and switching on master and slave are realized by arbitration. In consideration the complexity,reliability and implementation difficulty,a redundancy management method for task-level synchronization is proposed,which realizes the synchronization of task between the master and slave through the communication link and the task synchronization software running on the CPU module. This method not only meets the device synchronization requirement,but also easy to implement with low complexity.
