Problems solved by technology

[0002] Based on the ubiquitous power Internet of Things technology, the innovative application in the field of power loss reduction and intelligent anti-stealing in the power system, in the power system, the power supply area refers to the power supply range or area of ​​(one) transformer, which is the basis of power economic operation management Nouns, and in specific sentences, it is a place name of a region. The station area mostly includes regional power supply lines, substations, meter boxes and electric energy meter lamps, but existing power supply lines, station substations, meter boxes, and electric energy meters in some areas Correspondence files are inaccurate, metering box locks are seriously damaged by man-made external forces, power consumption without meters, and power theft outside meters are prominent. Most of the meters are version 2009 and 2013, and a small part of them have ERR-04 (battery undervoltage) alarms , here, the calculation of intelligent holographic perception and layered line loss of the power grid at the end of the station area is also of great importance
