The invention discloses a knowledge graph construction method and device for power grid main equipment, and belongs to the technical field of power grid operation and inspection. Through continuous exploration and test, basic information, operation data and operation content of power grid main equipment are subjected to structured processing, knowledge triple extraction, ontology construction and knowledge graph completion and reasoning of the power grid main equipment are achieved through a system tool, and then a knowledge graph of the power grid main equipment is constructed; the method is suitable for the power grid equipment, can be applied to a power grid operation and maintenance management and control platform, can provide an auxiliary decision for operation and maintenance commanders, effectively improves the processing capability of personnel and equipment abnormality and faults, improves the quality and efficiency of knowledge analysis and processing of the power grid equipment, reduces the operation and maintenance cost of the power grid equipment, and improves the power transformation operation and maintenance efficiency. According to the invention, the knowledge mining capability and the intelligent analysis service capability of the equipment management business can be effectively improved, and the informatization and intelligence level project range of power grid operation and maintenance is comprehensively improved.

The invention relates to a computer assistant reporting and knowledge-base generation method including the following steps: a server system receives requests of information search from users and searches all structured and unstructured web pages and websites matching the search requirements of users on the internet and a third-party database and also feeds the search results back to a client digital terminal system after classification, de-emphasis and compilation while matching the third-party database; the server system records the search behavior of a user and detects the updating of information resource and catches and classifies the updated information in real time so as to remind the user of the updating of the information resource when the user goes on line; the user selects the required information from the search results and collects the information into the system and the knowledge mining method is adopted to generate reports and derive files. The invention has the beneficial effects that the efficiency of searching, collecting and classifying the information is enhanced for the user, and the unstructured information can be converted into structured information and the semantic relevance between information can be preserved by human-computer interaction.
