Problems solved by technology

[0003] However, the disadvantage of PLC technology is that: distribution transformers have a blocking effect on power carrier signals, and the spatial range of signal propagation is limited; in addition, electromagnetic wave signals will attenuate within a range of tens of meters
However, this technology only stays in the remote meter reading technology (CN103743448A)
[0006] Augmented reality technology (AR) is one of the feasible solutions to solve the spatial distribution of on-site power operations. Although AR technology can realize on-site visual on-site equipment operation status monitoring (CN109947052A), the scope of implementation is limited to factories (CN111966068A) or households. (CN111505953A), so it is difficult to provide an intelligent monitoring scheme for the power operation of the whole city
[0007] In the monitoring basic data acquisition of electric power operation, in terms of abnormal signal detection of power carrier, the existing technology uses convolutional neural network to provide an intelligent identification scheme for electrical signals, but it is also limited to non-visual low-voltage power (CN112364753A)
