The Research Of Equipment State Management System For Coal Mine Based On Internet Of Things Technology

New opportunities are brought to various enterprises by the Internet of Thingstechnologies. Coal industry as China’s main economic pillar has the rapid developmentin recent years. All kinds of safety and production monitoring systems used for minehave been popular. However, because of limit of coal mine complex productionconditions, safety and production technologies have a low level compared to otherindustry. So to improve intellectualization and high efficiency of coal enterprisemanagement has the extremely vital significance. The Internet of Things have somefeatures such as total information awareness、reliable information transmission andintelligent processing, which has good application prospects in coal mine safetyproduction management.The system content of coal mine equipment state management system and therelation theories knowledge of the Internet of Things are introduced in this paper.Besides, key technologies and localization algorithm of the Internet of Things areanalyzed. On the basis of common Internet of Things models, this paper combine withpractical coal mine characteristics and has an improvement. The Internet of thingstechnologies applied to coal mine equipment management in the perceptual model andthe actual application model are putted forward. At the same time Proté g é3.3.1is usedto creating perceptual modeling, which supports information inference and extending.Ontology perceptive model is called through system software, which improves theequipment information retrieval efficiency. What’s more，feasibility of the applicationmodel is verified through the Internet of Things detailed design solution, includingsystem wireless network layout、communication process and the DLL design which allcombine with main work place in mine.The main research point of this paper is making the Internet of Things technologiesapplied to coal mine equipment state management system and on the basis of theimprovement of common Internet of Things models the practical Internet of Thingsmodel is also presented. The simulation experiment research of WiFi exact localizationalgorithm and improved localization algorithm is made. Positioning algorithm wasimproved and location accuracy is also improved. The process of system implementation is designed and the main function is completed. The management ofcoal mine equipment state will be more efficient and intelligent by studying relativeInternet of Things technologies and application practice process.
