针对物联网应用，提出了一种具有任务调度和自主待机模式切换控制的低功耗多传感器系统，该系统在非工作模式下实现了几乎为零的待机功率。具有活动本地化的电源管理方案可以通过重新调度和捆绑任务过程来减少开机和关机模式之间的转换次数。自主待机模式转换控制选择微控制器的最佳待机模式，降低总功耗。我们以评估板为例演示了物联网应用，通过采用任务调度和自主待机模式转换控制相结合的方式，观察到功耗降低了91%。
The low-power multi-sensor system with task scheduling and autonomous standby mode transition control for IoT applications are proposed, which achieves almost zero standby power at the no-operation modes. A power management scheme with activity localization can reduce the number of transitions between power-on and power-off modes with re-scheduling and bundling task procedures. And autonomously standby mode transition control selects the optimum standby mode of microcontrollers, reducing total power consumption. We demonstrate with evaluation board as a use case of IoT applications, observing 91% power reductions by adopting task scheduling and autonomously standby mode transition control combination.
