基于云电表环境的用电安全智能监控与诊断系统

AbstractWith the improvement of people's living standards,there are more and moretypes of electrical appliances in residential houses,and indoor power supply lines arebecoming more and more complex.Many students in the dormitory do not regardschool discipline and use electric kettles,electric cookers and other high-poweredcontraband appliances.While these phenomena have brought convenience to people,they have also created a number of security risks,such as electrical fires and electricshocks.Indoor electricity safety hazards and hidden dangers to the environment havecaused great threats to people's lives and property safety,and they have also broughtincalculable economic losses to the society.Therefore,monitoring and diagnosis ofindoor electricity protection has become a topic of common concern.At present,indoor power safety protection devices are mostly low-voltage circuitbreakers,which are commonly referred to as air switches.When the line current isoverloaded,they will be automatically disconnected.This type of device has arelatively single function and is incapable of power failures that are not easilydetected..This article from a new perspective,relying on sensor technology,computer network technology,embedded technology and other things related to theInternet of Things,designed indoor electricity security monitoring for large dataapplications for indoor security monitoring intelligent system.The load powercharacteristic parameter extraction algorithm based on current waveform acquisitionand analysis is adopted.In addition to the ability to monitor short-term,overload,andother real-time security risks,with the current rapid development of cloud computingprocessing methods,it is also possible to perform continuous status analysis on homecircuits.Designed to solve potential hazards that are not easily detected byconventional circuit protection devices,each home is provided with a safetymonitoring device for current extraction,analysis and calculation of the indoor powersupply line.This topic is of great significance for improving the safety monitoringeffect of ordinary houses,student dormitories,hotels and other places.On the other
