摘　　要：根据片上集成无线传感器节点光电微能源系统结构及传感器节点功耗,分析光电微能源系统各组成部分的能量参数和系统的能量转换、存储及传输机理,建立了片上集成光电微能源系统理论模型。另外,对能量存储、分配及无线传感器节点工作方式等对系统设计参数的影响进行了分析,同时,对能量存储式和能量暂存式两种能量存储模式对系统设计的影响进行了比较。结果表明,光电微能源不同的工作方式及能量管理模式直接影响微能源系统设计参数及工作特性。理论模型及分析结果为片上集成光电微能源优化设计奠定了理论基础及参考依据。The energy parameters of the photoelectric micro-power supply are analyzed based on the system structure characteristics and the power consumption of wireless sensor nodes. Meanwhile,the design theory model of the micropower supply is established by using the mechanism of the energy conversion,storage and transmission on the micropower supply. In addition,the infection of the energy storage mode,distribute mode and the sensor node working mode on the system characteristics and the design parameters is analyzed by using the design theory model. Meanwhile,the influence of both the energy management mode of the energy storage and energy buffer on the design model of system is analyzed. The results show that the system working and energy management mode are the main factors to affect the design parameters and working characteristics of the micro-power supply. The design theory model and analysis results lay a theoretical foundation for optimization design of the micro-power supply on chip.
