Electric power engineering supervision data management system and method based on block chain

The invention discloses an electric power engineering supervision data management system and method based on a block chain. The system comprises an acquisition unit and a data management center. And the acquisition unit is used for automatically acquiring operation state data of the electric power engineering project or periodically according to an instruction sent by the data management center and sending the operation state data to the data management center. The data management center sends an instruction to start or periodically and automatically collect the operation state data of the electric power engineering project, and the collection mode is flexible; corresponding health evaluation models are selected according to the types of the electric power engineering projects, and different types of the electric power engineering projects correspond to different training sample data, so that the pertinence of model training and the accuracy and reliability of evaluation are ensured; when the storage module w
