| Coal mine safety management has been an urgent and important subject. With the emergence of the internet of things technology, it is urgent to apply this new technology to the safety production of coal mine. However, due to the limitations of people’s understanding of the internet of things technology. At present, the coal mine monitoring system based on internet of things has not yet formed a unified standard for construction. Therefore, according to the connotation of the internet of things technology and the establishment of the coal mine to establish a comprehensive evaluation index system of coal mine monitoring system, and on this basis, using scientific evaluation methods to evaluate the level of construction and application of coal mine monitoring system, it is of great significance to regulate, guide and promote the construction of coal mine safety.The process of comprehensive evaluation of coal mine monitoring system is an activity of evaluation by people. There is a large amount of unknown information. Therefore, this paper introduces the theory of uncertainty measurement into the evaluation of coal mine monitoring system, establishing a comprehensive evaluation model of coal mine monitoring system based on the theory of uncertainty measurement. First of all, the establishment of evaluation index, this paper is based on the combination of coal mine monitoring system architecture and construction requirements, then considering the characteristics of coal mine accidents occurred in recent years and the views of the coal industry experts, and summarizing the influence factors of coal mine monitoring system, and establishing the preliminary evaluation index system. Secondly, basing on the analysis of the adaptability of the theory of the uncertainty measurement to the evaluation of coal mine monitoring system, introducing the theory of the uncertainty measure, and combining with the establishment of the evaluation index system, establishing the uncertainty measurement model of coal mine monitoring system. In the process of model construction, the determination of the index weight value is based on the information entropy theory, making the weight value more scientific and objective.Finally, in order to solve the disadvantages of the calculation process of the evaluation model, the software system of coal mine monitoring comprehensive evaluation is developed based on eclipse software development platform, which makes the evaluation model more practical. Taking Ma Lan coal mine monitoring system as evaluation object to test the reliability of the evaluation software system. According to the evaluation results proposing improvement suggestions. |
