Research of the Integration Model of Coal Heterogeneous Systems

This paper was linked to the requirement of coal mine information construction, firstly, on the basis of heterogeneous data environment of the coal mine to sort out, induction, classification, we established an integrated model from the coal underlying data to the application layer, which includes 4 layers: data acquisition layer, data source layer, intermediate interface layer, application layer. The model focused on the underlying data integration and intermediate interface layer data integration, put forward a design idea, which includes mine underlying data integration based on OPC interface and intermediate interface layer based on virtual database and data warehouse, the intermediate interface layer has 4 layers, they are virtual database sub-layer, the data warehouse sub-layer, meta-database sub-layer and service management sub-layer. The coal comprehensive integrated model provides a unified data access platform for integrated data query, 3D visualization integration, Mine Safety forecast and intelligent decision.
