Abstract：To address the deep-level coordination challenges across multi-vendor and cross-generation systems during the smart mine platform construction of Lijiahao Coal Mine,it was proposed to adopt a hierarchical control architecture for the collaborative control system.The hierarchical collaborative control system was proposed,featuring three core layers:A communication interface layer with an OPC UA-based protocol conversion gateway enabling compatibility among RS485,industrial Ethernet,LoRa,and other protocols;A data fusion layer employing reinforcement learning algorithms for spatiotemporal alignment of multi-source data,facilitating the construction of a mine digital twin;An intelligent coordination layer incorporating an event-driven dynamic coupling algorithm and a decision matrix integrating 32 state parameters.Application test in Lijiahao Coal Mine demonstrated significant improvements:emergency response time was reduced to 9.7 seconds and comprehensive equipment energy efficiency was 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 was achieved.
