Among them, the design of the energy harvesting coil that directly harvests energy from the high-voltage side has extremely high requirements on the insulation performance of the material, and because the current load changes irregularly and greatly, it is difficult to achieve stable voltage output while ensuring system safety; However, solar panels and small wind turbines depend on the local meteorological environment when they work, and their output voltage is unstable. It needs to be stabilized by a stable power conversion module before charging the battery. The capacity of the battery needs to be carefully designed to meet the rainy conditions for several consecutive days. The power supply process of the battery to the monitoring system needs to be controlled by the discharge module to prevent the battery from being over-discharged and prolong the battery life.
