摘要：

针对物联网边缘节点能源消耗需求快速增长问题，提出一种调度器优化策略，整体降低边缘节点能耗。在典型的物联网多核终端系统的电源管理架构及能耗特性的基础上，分析现有 Linux 系统电源管理存在的不足，提出改进调度器策略来优化系统能耗控制，并给出了该策略的实现过程及实施要点。该策略在多核模拟系统中进行了测试，结果表明，在低负载的运行场景，即CPU不需要进行大规模运算处理的情境下，如数据采集、设备监控等物联网典型应用场景，该策略节能效果明显。

Abstract:

A scheduling strategy to optimize energy consumption was proposed to reduce the energy consumption of the edge system in view of the fast growth of energy consumption demand in the internet of things.Based on the analysis of the power management architecture and the energy consumption composition in the typical multi-core terminal system,in view of the shortcomings of the existing system power management module,the scheduler load balancing mechanism was improved to control system energy consumption and the implementation process and implementation points of the strategy were given.The strategy was tested in the multi-core simulation system.The result shows that in low load scenarios,that is,in scenarios that CPU does not need to do data-intensive computing,the energy-saving effect of this strategy is obvious,such as data acquisition,equipment monitoring and other typical internet of things applications.
