Uninterrupted maintenance method based on big data fusion analysis and taking reliability as center

The invention relates to the technical field of uninterruptible power operation maintenance, and particularly discloses an uninterruptible power maintenance method based on big data fusion analysis and taking reliability as a center, comprising the following steps: S1, a maintainer turns on a switch in a high-voltage power distribution cabinet, and waits for an indicator light to be turned off and a safety light to be turned on; s2, if the fault problem of the to-be-detected line is mastered, entering a step S3, and if the fault problem of the to-be-detected line is not mastered, entering a step S4; s3, the maintainer starts a recording function on the maintenance helmet, records the maintenance information and shoots the maintenance process, and finally uploads the maintenance information to the cloud; s4, a maintainer opens a maintenance detailed solution module and searches for a maintenance guidance video of a fault problem, if the maintenance guidance video is found, maintenance is carried out according
