Maintenance case information query method and device, electronic equipment and storage medium

The invention provides a maintenance case information query method and device, electronic equipment and a storage medium. Firstly, to-be-queried fault information is acquired; performing feature extraction on the fault information to be inquired to obtain a fault feature vector; calculating the similarity between the fault feature vector and a case fault feature vector corresponding to each piece of maintenance case information; and finally, through the similarities, selecting target maintenance case information from the maintenance case information as a query result corresponding to the to-be-queried fault information. According to the method, professional engineers do not need to carry out field services, the target maintenance case information can be determined in a query mode, then the corresponding maintenance information is found, and a user can maintain the fault equipment through the maintenance information, so that the labor cost can be greatly reduced, and the fault positioning time consumption and
