Design and implementation of non-intrusive electrical appliance online monitoring system based on Internet of Things

针对当前智能电网和电力互联背景下非侵入式负荷监测存在的不足,本文设计并实现了一种基于物联网的用电器在线监测系统。系统通过CS5463电能采集芯片获得用电器特征电参数,利用STM32运行FFT算法和一种多维识别算法,实现用电器的非侵入式监测。识别和监测信息经ZigBee传输至服务器中,用户端可通过Qt上位机远程访问数据来在线监测。从实验结果来看,该系统很好地实现了非侵入式监测的功能,能准确识别用电器并在线实时监测用电器工作状态,系统可实施性强,为智能家居和电力物联发展提供技术支撑。

Aiming at the current problems of non-intrusive load monitoring in the context of smart grid and power interconnection,an online monitoring system for electrical appliances based on the Internet of Things is designed and implemented.The system obtains the characteristic electrical parameters of electrical appliances through the CS5463 electric energy acquisition chip,and uses STM32 to run the FFT algorithm and a multi-dimensional recognition algorithm to realize the non-intrusive monitoring of electrical appliances.The identification and monitoring information is transmitted to the server via ZigBee,and the user can remotely access the data through the Qt host computer for online monitoring.The experimental results show that the system has realized the function of non-intrusive monitoring.It can accurately identify electrical appliances and monitor the working status of electrical appliances online in real time.The system is highly implementable and provides a great opportunity for the development of smart homes and power IoT technical support.
