基于能量收集和BLE的低功耗有源标签设计

摘要

This paper aims to design an ultra-low-power active labelbased on energy harvesting and BLE. The whole system consists mainly of energy harvesting module,power management module and wireless data transmission module.Energy harvesting module is composed of SLMD121H04L,realizing solar energy to electrical energy conversion.Power management module is composed of BQ25570,realizing the whole sys-tem's power management.Communication module is composed of DA1458,realizing the data communication protocol of wireless transmission and are consistent with iBeacon communication protocol.%该文旨在利用能量收集和BLE来设计一个超低功耗的有源标签。整个系统主要由能量收集、电源管理和无线数据传输三部分组成。其中能量收集模块主要由SLMD121H04L组成，实现光能到电能的转换；电源管理模块主要由BQ25570组成，实现对整个系统的电源管理；通信模块主要由DA14580组成，实现数据的无线传输并且符合iBeacon通信协议。
