Construction method and device of manufacturing industry equipment knowledge graph

The invention relates to the technical field of manufacturing industry, and discloses a manufacturing industry equipment knowledge graph construction device, which comprises a body construction module used for constructing an equipment knowledge graph by using a body construction tool to form a knowledge graph mode layer. According to the construction method of the manufacturing industry equipment knowledge graph, firstly, a Hertrix crawler framework is used for collecting manufacturing industry equipment data, then a third-party original database is independently stored, the data in the first step are classified, the collected data are divided into structured data, semi-structured data and non-structured data according to types, and the data are stored in the third-party original database; combining the structured data with the third-party original database, supplementing the third-party original database to generate the new database, generating an entity link from the semi-structured data and the non-struct
