Data processing method and device, electronic equipment and storage medium

The invention provides a data processing method and device, electronic equipment and a storage medium, relates to the technical field of computers, and solves the technical problem that effective use of operation and maintenance data cannot be ensured due to different standards of personnel checking and more uncontrollable factors. The method comprises the steps that at least two data sets are obtained, one data set comprises at least one piece of operation and maintenance data, and the type of the operation and maintenance data included in the at least two data sets is the same as the data type corresponding to a target detection task; operation and maintenance data to be identified are retrieved based on the fault tree, whether feature codes of the operation and maintenance data to be identified exist in the fault tree or not is determined, and the operation and maintenance data to be identified are operation and maintenance data included in the at least two data sets; and under the condition that the featu
