VxWorks操作系统电源管理研究

Study on Power Management in VxWorks System

电源管理已成为嵌入式系统的一个重要研究方向,本文从顶层控制策略入手,研究并实现Vx Works操作系统电源管理的关键技术。在分析传统嵌入式系统电源管理的基础上,从电源管理策略角度分析传统电源管理,针对传统电源管理存在的问题,提出嵌入式电源管理系统关键技术并应用于Vx Works系统中,经实验测试,明显降低了系统电源功耗;实验结果表明,此方案提高了系统电源利用效率。

The effective power management of the embedded system is becoming an important re- search direction. By the top level of the controlled strategy, this paper studies and implements the pivotal technology of the power management. After disadvantages of the traditional power manage- ment system in embedded device are discussed from a strategic point of view, an advanced power management scheme of the embedded system is introduced and applied to the VxWorks system. With the development and practice of the actual project, the system power consumption is reduced signifi- cantly. And the experimental result shows that the advanced power management scheme is effec- fives.
