摘要

For the wireless sensor node integrated with photoelectric micro-power supply, the photoelectric micro-power supply (PMPS) determines their life time, stability and adaptability to the local environment. The design of PMPS involves the study related to incident light power, photoelectric conversion efficiency of solar cells, characterization of storage devices, energy management and operation state control of sensor nodes, etc. The design process of PMPS is complicated. In this study, in order to simplify the design process of the PMPS and optimize it, we analyze all of the power parameters for the PMPS for sensor nodes. According to the energy transmission modes of PMPS for sensor nodes, the design model of PMPS is established. The rationality of PMPS is verified by experiments and simulations based on wireless sensor node (Ginze3).
