The invention discloses a management method based on multiple energy collection, which can ensure the integrity of data transmitted and received by a node and can effectively reduce the leakage and loss of system energy. The method comprises the steps of: firstly, using an antenna to receive a radio frequency signal, designing impedance matching, and performing multistage voltage doubling, so thatthe charging voltage and the energy utilization efficiency are improved; secondarily, selecting a super capacitor to ensure sufficient energy storage, obtaining an approximate normal distribution relationship between the capacitor energy utilization efficiency and the capacitor voltage through a central limit theorem, and solving an optimal charging and discharging interval of the capacitor; thirdly, designing a finite-state machine in the system to control charging and discharging states, and ensuring the integrity of node data transmission. The method can lay a foundation for large-scale deployment of the Internet-of-Things without limitation of batteries.
