Framework and key technologies of Internet of things for precision coal mining
Abstract
On the basis of analyzing existing problems of coal mine production logistics system, concept and connotation of Internet of things(IoT) for precision coal mining were proposed and five key technologies were condensed by summarizing scientific conception of precision coal mining and development of mine IoT, which were intelligent perception of multi-source information, multi-network fusion transmission, multi-parameter information analysis and processing, disaster monitoring and early warning based on cloud technology and mine disaster emergency rescue. It was pointed out that precision coal mining based on transparent earth and intelligent perception based on IoT were two major technical systems to realize future unmanned mining, precision coal mining was technology core, and IoT was technical guarantee. Taking IoT for dynamic disaster precision early warning of coal mine as an example, its system framework was expounded including perception layer, network layer, application layer and public technology, and its engineering application was introduced, which directed technology route for precision coal mining.
