物联网低功耗评估方法分析

Analysis of Low-power Evaluation Methods for the Internet of Things

传统功耗检测方法是利用功率计对样品进行瞬时功率评估或者积分评估。由于智能物联网无线产品工作状态时间短、电流动态波动数量级差异大、连接公共基站时无法精确地控制样品的工作状态等因素,传统功耗检测方法无法正确地评估物联网低功耗问题,也无法评估电池在产品耗电特征下的有效容量和有效使用时间。根据智能物联网无线产品的特点,介绍了物联网产品低功耗和电池续航时间的评估方法,并对主流评估方法进行了分析总结,以期为物联网低功耗评估方法的选择与优化提供一定的参考作用。

The traditional power consumption detection method is to use power meter to evaluate the instantaneous power or integral of the sample.Because of the short working time of IoT wireless products,the great difference of current dynamic fluctuation,and the inability to control the working state of samples when connecting to common base stations,the traditional power detection methods can not evaluate the low power problem of IoT,also cannot evaluate the effective capacity and the effective life time of the battery under the power consumption characteristics.According to the characteristics of IoT wireless products,the evaluation methods of low power consumption and battery life are introduced,and the main evaluation methods are analyzed and summarized so as to provide a certain reference role for the selection and optimization of IoT low-power evaluation methods.
