【摘要】 针对电力直流监控系统的可靠性要求,采用实时双机嵌入式容错系统的设计以实现功能。采用了基于内核抢占式的实时多任务操作系统C/OS-Ⅱ进行容错设计、修改了内核调度,并讨论、验证了容错的任务可调度性。可靠性检测结果表明,双机容错系统的功能可以满足实际要求。更多还原

【Abstract】 The real fault-tolerant dual embedded computer is established to achieve reliability of the direct current monitoring device used in power electrical system.A real embedded preemptive multi-task operation system C/OS-Ⅱ is applied in this system and the schedule function is rewritten to realize fault-tolerant.Based on this design,the schedulability of real task is discussed also.The reliability analysis for test results showed that the performance of dual fault-tolerant system designed could meet the demands.更多还原
