Abstract:

To address the deep-level coordination challenges across multi-vendor and cross-generational systems during the construction of Lijiahao Coal Mine's smart mine platform, the proposed collaborative control system adopts a hierarchical control architecture. A hierarchical collaborative control system is proposed, featuring three core layers: 1) A communication interface layer with an OPC UA-based protocol conversion gateway enabling compatibility among RS485, industrial Ethernet, LoRa, and other protocols; 2) A data fusion layer employing reinforcement learning algorithms for spatiotemporal alignment of multi-source data, facilitating the construction of a mine digital twin; 3) An intelligent coordination layer incorporating an event-driven dynamic coupling algorithm and a decision matrix integrating 32 state parameters. Application testing at Lijiahao Coal Mine demonstrated significant improvements: emergency response time reduced to 9.7 seconds and comprehensive equipment energy efficiency enhanced by 19.3%. By constructing a unified communication protocol stack and data fusion mechanism, and establishing a dynamic coupling model across systems, intelligent collaborative management and control of the mine production system has been achieved.
