In view of the problems existing in the low-voltage terminal of power grid, such as management data segmentation, extensive management of the station area, low failure handling rate of low - voltage distribution network, and more customer complaints,the full sense of low -voltage terminal is proposed from the aspects of IOT perception, data management, data supermarket and data application by using large data, Internet of Things, edge computing and so on. Based on full-perception platform, through deep mining of the data value of smart tables, the integration of business terminals and grid management of stations can be realized, which can provide comprehensive and unified support for many applications,such as active operation and maintenance, smart user interaction,differentiated user service, accurate user marketing, and so on, so as to achieve both internal management and external service. The construction of low-voltage terminal full perception platform opens up a new way for safer operation, more lean management, more accurate investment and better customer service of power grid.
