摘要
为了解决电力监控系统信息高效交互和传输的问题,提出了一种改进的最久未使用页面交换算法.通过对不同电力监测终端节点需要传送的信息进行事件建模,总结不同场景的页面交换特点,得到能够反应监测节点对不同事件场景的概率模型.通过设定具体的场景阈值,结合对应的概率模型和最久未使用页面交换算法制定新的页面交换策略,从而提高整体系统的运行效能和稳定性.结果证明,所提出的算法可以比同类其他算法提高至少10%的性能.
In order to solve the problem for efficient information exchange and transmission of power monitoring system,an improved algorithm for the least recently used page was proposed.Through the event modeling for information needed to be transmitted by different power monitoring terminal nodes,the page exchange characteristics of different scenarios were summarized,and a probability model capable of responding to different event scenarios of monitoring nodes was obtained.Through setting specific scenario thresholds and combining the corresponding probability model with the exchange algorithm for the least recently used page,a new page exchange strategy was developed,and the performance and stability of overall system were improved.The results verify that the as-proposed algorithm can improve the performance by at least 10%in comparison with other algorithms.
