Summary: The paper proposes an energy-aware mode switching strategy for IoT nodes to perform either on-demand sensing or dedicated wireless power transfer. It includes a scheduling scheme to maximize the utility of IoT nodes by considering residual energy and energy required for sensing tasks, as well as a transmitter scheduling scheme to minimize charging costs while keeping IoT nodes sufficiently charged. Simulation results show significant energy reduction in the overall system with less than 50% of IoT nodes and less than 60% of energy transmitters activated in all scenarios.

Summary: The current leakage fault diagnosis methods in rural areas have low accuracy and efficiency. To address this issue, a rural power leakage diagnosis system based on narrowband Internet of Things is studied and designed. By proposing a magnetic modulation sensor with a double magnetic core structure, the problem of zero drift and temperature drift in a single magnetic core structure is solved, thus reducing measurement errors. Additionally, a half-wave excitation scheme is proposed to improve the output voltage waveform of the sensor and reduce calculation complexity. The experimental results demonstrate that the designed rural power grid leakage diagnosis system achieves a diagnostic accuracy of 95%. In conclusion, the rural power grid leakage diagnosis system effectively enhances the accuracy of power grid leakage diagnosis and provides support for the livelihood and economic development of rural communities.
