Abstract: Against the backdrop of in-depth integration of informationization and industrialization, to actively practice the integration and building of smart Coal preparation plant to realize improvement of product quality and operating efficiency has become an important developing direction of coal preparation sector. In the process for the development of smart coal preparation plant, a part from the due considerations that should be given to the use of new equipment and technologies, upgrading of coal washing processes, and realization of information-based automated operations, to effect washing equipment intelligent health management is of particular importance. An introduction is made in the paper to the schemes adopted for practicing this management mode by applying the IOT framework-based technical means, including Internet information transmission, industrial cloud management platform, big data analysis and intelligent expert diagnosis, among others, so as to help upgrade the information-based automated plant to become an intelligent one, in a rapid and cost-effective manner.
