Residential power monitoring method and system based on power line communication

Abstract

The invention discloses a residential power monitoring method and system based on power line communication. The method comprises that all household electrical appliances and an intelligent electric meter in a house are connected with a central controller to complete networking; the central controller collects power utilization data of each household electric appliance, stores the data in a database, and displays the data via reports; and the central controller detects whether abnormity occurs the household electrical appliances, and if yes, warming is sent to a user terminal. According to the invention, all the household electrical appliances are connected to the residential intelligent network, simple interaction protocols are combined with instant messaging technology to monitor and analyze the appliances in the network as well as the power utilization condition of the appliances, early warning is given to the appliance that is connected to the network newly, and alarming is raised against abnormal power utilization condition.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a method and system for monitoring residential electricity consumption based on power line communication. Background technique [0002] One of the core contents of a smart home is the interconnection and interaction between household appliances. Currently, the most common home appliance communication technologies include infrared, Bluetooth, WIFI, DLNA, IGRS and other technologies and standards. These protocols use short-distance wireless communication technology, but due to the increasing number of household appliances, the interference between signals of different devices, and the different room layouts also have a great impact on the effectiveness and stability of the entire home network communication. To a certain extent, it limits the experience of using many smart home products. [0003] In addition, due to the generally low intelligence program of ordinary household ap...
