Abstract

The invention provides a fault indicator flipping identification method and device and a power distribution network fault monitoring system, and the method comprises the steps: collecting at least onetarget picture of a fault indicator through an image collection part; comparing each target picture with the reference picture of the fault indicator corresponding to the target picture, and determining picture similarity information which is used for representing the similarity between the target picture and the reference picture; and according to the picture similarity information, determiningwhether the fault indicator is flipped or not. Therefore, whether the fault indicator is overturned or not can be automatically judged by utilizing the acquired target image.

Description

technical field [0001] The invention relates to the field of distribution networks, in particular to a method and device for identifying fault indicators and a fault monitoring system for distribution networks. Background technique [0002] The distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or distributes it to various users step by step according to voltage. [0003] In a distribution network such as a medium-voltage distribution network, a distribution network fault monitoring system can be configured, which can monitor the occurrence of short-circuit faults, ground faults, etc., and can use fault indicators to display fault conditions feedback. [0004] However, in the existing related technologies, personnel are required to check the fault indicator to know in time whether the fault indicator has flipped, which consumes...
