Abstract: To improve the efficiency of distributed photovoltaic maintenance industry,a matching method for maintenance scheme based on professional domain knowledge graph was designed.The maintenance scheme based on maintenance requirements and the distributed photovoltaic maintenance knowledge graph was matched accurately,which provided scheme support for maintenance personnel.A method of matching maintenance scheme with the knowledge graph as a bridge was presented.The matching process was improved according to the complex type of maintenance requirements.In view of incomplete requirements in practice,the method was enabled to match the scheme by inference with the knowledge graph.Experiments showed that the improved approaches helped to provide a higher degree of accuracy and better reliability.
