Reliability Evaluation of Coal Mine Internet of Things
Pan Kunkun, Xiangong Li · 2014
In order to sense and control the complicated hazards in process of mining, the Internet of Things has been applied to coal mine production. The safety management in coal mine highly relies on the reliability of coal mine Internet of Things. In this paper, the hazard theory, system security theory and risk analysis theory have been used to screen the evaluation indexes. Analytic hierarchy process and mean square error method were applied to determine the weight of each index and establish a comprehensive evaluation system. Finally, we used the application status of Internet of Things in Jiaozuo Coal Industry Group for an analysis example in this paper, obtained the key factors affecting the reliability of coal mine Internet of Things, and gave recommendations.
