Research on information visualization of smart mine

Existing information visualization researches of smart mine focus on 3D virtual scene building and real scene monitoring, but ignore selective visual display considering focus points of managers. For the above problems, based on general structure of smart mine of four transversal layers and three longitudinal systems, visualization information framework of smart mine is built by use of visualization mode selection model of ISVE(Information-Subject-Visualization-Effectiveness). Information systems of smart mine are divided into engineering digitization system, integrated automation system and management informationization system. Information in each system is classified on basis of service-object-oriented thought, and attributes of each type of information are researched. A selection thought of information visualization mode is proposed which takes cognition agent as a core. Appropriate information visualization mode should be selected according to information focus points of executives in each management layer of coal mine enterprise, so as to improve cognition efficiency of executives and promote development of informationization and intelligence of coal mine enterprise.
