Study on Key Technologies of Digital Mine Integrated Transmission Platform

On the analysis of the development, functions and frame structure of Digital Mine(DM), some key technologies such as topology structure, transmission layer system, inter-ring connection method and structures of normal node and cross connection node in the integrated transmission platform were studied in this paper. It was proved to be more reasonable that the branch of DM integrated transmission platform was built following the hybrid of ring and tree topology. DM integrated transmission network includes ring based mine area trunk network, ring based on mine ground part network and ring based under mine part network. All the rings connect with each other tangency. Referring to RPR technology, the transmission system was designed with some optimization work. And traffic can be transmitted between rings with high efficiency and reliability here. Finally the redefined frame format for DM integrated transmission platform and functional architecture of both types of nodes was set up.
