摘　　要：探讨应用实时系统低功耗管理方面的研究成果对实时数据库系统(RTDBS)节省能耗技术进行扩展。提出通过实时事务空闲时间在CPU及磁盘之间的优化分配;实时事务协同优化设置保存点;综合考虑实时事务关键性与能耗需求及事务执行价值的能量分配策略;优化的CPU及磁盘的速度调节等来实现节省RTDBS总能耗的统筹解决方案。Based on the research results of low-power consumption management in real-time systems the power saving technologies are applied in Real-Time Database System （RTDBS）. The paper tries to achieve the overall power saving solution in RTDBS by optimizing allocation of real-time transactions slack time between CPU and disks; collaboratively and optimally setting saved-points; comprehensively considering the transactions weightiness and power needs of real-time transactions, and the power allocation strategy of the transaction execution value; and the optimal CPU and disk speed adjusting, etc.
