The data fusion platform mainly provides full-process management covering data collection, connectivity, governance, application and evaluation. It enables efficient data acquisition and aggregation, adapting to various protocols through flexible configuration to realize unified collection of multi-source heterogeneous data. Meanwhile, it conducts data cleaning and fusion via intelligent in-depth data governance to improve data quality, and lays a foundation for subsequent data sharing and application through standardized and modeled data management. Most importantly, in terms of data application, in addition to basic real-time monitoring of business data, the platform primarily offers holographic information fusion display and collaborative linkage control for key 3D visualized business scenarios based on GIS, as well as multi-dimensional data analysis, providing effective support for safe production and decision-making management in coal mines.
