一种基于微能量采集和节能模式设计的节能方法

Energy-saving Method Based on Micro-energy Harvesting and Energy-saving Mode

本文以计步器为例,探讨了一种基于微能量采集和节能模式设计的节能方法。一方面要选取合适的低功耗芯片,设置合理的低功耗工作模式;另一方面,采用TI公司的升压转换器芯片BQ25504设计微能量采集方案,通过采集周边环境中被浪费的能量供设备使用,以增强设备的续航能力。通过这两方面的节能设计,使计步器的待机时长超过900小时,其节能技术还可广泛应用于其他可穿戴智能硬件产品。

Taking the pedometer as an example,an energy-saving method based on micro-energy harvesting and design of energy-saving model has been researched.On the one hand,appropriate low-power chip is chosen,and reasonable working mode is set.On the other hand,micro-energy harvesting module is designed based on boost converter chip BQ25504 of TI.Wasted energy is harvested to enhance the working time of the device.Based on these,the working time of the device is beyond 900 hours.Moreover,the technology of energy harvesting can be used in other wearable devices.
