摘　　要：针对目前嵌入式设备对低功耗的要求,提出一种新的电源管理算法,对传统指数平均预测算法进行改进,改进后的算法解决了原本由于指数因子的值固定以及对历史空闲时间的取值范围模糊而导致的算法精确度不高的问题。同时改进后的算法具有可根据情况实时进行动态自我调节的优点。经过改进,将延长嵌入式设备的连续工作时间,提高设备的稳定性。In view of the present embedded devices with low power consumption requirement, this paper presents a new power management algorithm, to improve the average index of traditional prediction algorithm, the improved algorithm has solved the original because the index factor is the value of the fixed and free time in history the value range caused by fuzzy algorithm of accuracy is not high. At the same time, the improved algorithm has advantages can be dynamically according to the real-time situation of self-adjustment. After improvement, this paper will extend the embedded equipment continuous working time, improve the stability of the equipment.
