Method and device for acquiring data of data sources associated with production line

A device for acquiring data of data sources associated with a production line, comprising:

• a model acquisition model, configured to acquire a semantic model, the semantic model including semantic relationships between each of a plurality of semantic units and corresponding data source identifiers of at least one production line;
• a receiving unit, configured to receive production line identifiers and acquire at least one semantic unit;
• a conversion unit, configured to convert the at least one semantic unit to the corresponding data source identifiers of the at least one production line indicated by the production line identifiers based on the semantic model;
• and
• a data acquisition unit, configured to acquire data of the data sources indicated by the data source identifiers wherein the acquiring of the semantic model comprises,
• establish a virtual model of the at least one production line based on characteristic information and production sequence of constituent parts of the at least one production lines,
• creating a contextual information library based on the virtual model, the contextual information library including contextual information of data sources of the at least one production line, and
• connect each of the plurality of semantic units and the corresponding data source identifiers of the at least one production line with semantic relationships based on the virtual model, the plurality of semantic units and the contextual information library forming the semantic model.
