一种基于LabVIEW的物联网设备功耗测试方法的研究

The Research on Power Consumption Test Method of Internet of Things Based on LabVIEW

绝大多数物联网的终端设备都需要使用电池供电,为了尽可能延长续航时间,这些设备都配备了各种超低功耗睡眠模式和完善的功耗限定装置。物联网设备的操作时间通常很短,会不定时发生电流值快速跳变,而且情形非常复杂,涉及多种运行模式。使用传统测试仪器已很难捕获此类复杂情况下的电流、电压、功率等功耗测试参数。所以,准确描述每台设备的功耗及系统级整体运行时的功耗情况,在降低能耗及优化电池续航时间方面发挥着至关重要的作用。因此,基于LabVIEW软件设计了一种物联网终端设备的功耗测试系统,具备实现精准测量、自动分析、直观显示的功能,提高了物联网设备功耗测量实验的检测效率。

The vast majority of Internet of Things terminal devices need to use battery power.In order to extend the service life as much as possible,these devices are equipped with various ultra-low power sleep modes and perfect power consumption limiting strategies.The operation time of Internet of Things equipment is usually very short,the current value changes rapidly and occurs irregularly,and it is very complex,involving a variety of operation modes.It is difficult to capture the current,voltage,power factor and other power consumption test parameters under such complex conditions by using traditional test instruments.How to accurately describe the power consumption of each device and the overall system level power consumption plays an important role in reducing energy consumption and optimizing battery life.Therefore,this paper designs a power consumption test system of Internet of Things terminal equipment based on LabVIEW software,which can achieve accurate measurement,automatic analysis and intuitive display functions,and improve the detection efficiency of power consumption measurement experiment of Internet of Things equipment.
