【摘要】 致力于提高电网实时数据平台的性能,针对实时数据平台中实时任务的特点,在分析了常用的实时任务调度策略的优点和局限性的基础上,改进了传统调度算法,提出了一种基于优先级的新的实时调度策略,既考虑了任务的截止期,又兼顾了任务的关键性。然后研究了在多服务节点条件下,根据加权负载率和截止期错失率来实现任务分配的均衡性,从而大大改善了实时数据平台的性能。最后设计并实现了一个任务调度的解决方案,并通过模拟实验对其性能进行了分析,验证了新算法的优越性。更多还原

【Abstract】 The performance enhancement of the realtime data platform for power gird is studied.According to the feature of realtime task in the real-time data platform,some strategies of real-time scheduling task are analyzed.A better strategy for real-time data platform is proposed.The deadline and importance of task are considered.In order to improve the performance,assigned tasks are balanced based on the load percentage and missed deadline percentage.A solution scheme for scheduling real-time task is designed and implemented.Its performance is analyzed.Simulation results show that the new algorithm is prior to the traditional ones.更多还原
