The invention provides a current grounding fault direction judgment system and method, and relates to the technical field of fault recognition, and the method comprises the steps: integrating the feature codes of a fault region into a data set through a region module, marking region characters, transmitting the data set to a matching module, and carrying out the recognition of a current grounding fault. After the processing center receives the characters transmitted by the area module, the processing center enables the historical data block to integrate the historical fault data corresponding to the characters and the feature codes into a fault set according to the characters, enables the historical database to transmit the fault set to the matching module, and the matching module carries out data matching on the data set and the fault set. Through the system, the feature code of the fault area only needs to be compared with the fault set in the corresponding area in the historical data frame and does not need to be compared with all the fault sets in the historical data frame, the data comparison process is simplified, the fault data comparison efficiency is improved, and the fault point of line segment current grounding can be quickly positioned.

The invention relates to a document duplicate checking method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring at least two documents to be subjected to duplicate checking; for each document to be subjected to duplicate checking, determining a text vector corresponding to a document text in the document to be subjected to duplicate checking, and determining an image set corresponding to a document image in the document to be subjected to duplicate checking; any two documents to be subjected to duplicate checking are selected as a first document and a second document respectively; according to the content similarity of the document content of the first document and the document content of the second document under different content categories; and according to the content similarity under the different content categories, determining the repetition degree between the first document and the second document. By adopting the method, the document comparison efficiency can be improved, and the document auditing efficiency and accuracy can be improved.
