Abstract: There are many underground systems in the coal mine. As the agreements are not unified, it is difficult for the systems to be interconnected. Firstly, the advantages of advanced technologies such as SDN and DDS are introduced. The scheme of establishing distributed intelligent network platform in underground coal mine using DDS technology, SDN technology, distributed storage, distributed computing and other technologies is realized. The design method of intelligent switch, intelligent base station and other core equipment is proposed. Meanwhile, the data interaction method based on DDS open protocol is designed.
