摘要:
针对智能电表的功耗和成本问题，设计验证了一种降低功耗的动态管理方案。该动态功耗管理方案对不同的任务进行了类别划分，改进了动态模式切换，使得系统更早更合理的进入低功耗模。在无法进行工作模式切换的条件下，使用简单的动态频率调节进一步降低功耗，并详细阐述了方案的实现方法。同时，制作了智能电表样机，在样机上应用并验证了该动态管理方案。根据样机的验证结果表明，在智能电表应用该功耗动态管理方案后，样机的平均工作频率有所降低，智能电表功耗有效的降低。
Abstract:
Aiming at the power consumption and cost of smart meter, a dynamic management scheme to reduce power consumption is designed and verified. The dynamic power management scheme classifies different tasks, improves the dynamic mode switching, and makes the system enter the low-power mode earlier and more reasonably. Under the condition that the working mode cannot be switched, a simple dynamic frequency adjustment is used to further reduce the power consumption, and the implementation method of the scheme is described in detail. At the same time, the smart meter is made, and the dynamic management scheme is applied and verified on the smart meter. According to the verification results of the prototype, the average working frequency of the prototype is reduced and the power consumption of the smart meter is effectively reduced after the application of the power consumption dynamic management scheme.
