Application research of technologies of Internet of Things, big data and cloud computing in coal mine safety productio

The paper expounded research status of technologies of Internet of Things, big data and cloud computing, and indicated relations of the three technologies, namely the Internet of Things produces the big data, the big data boosts the Internet of Things; the big data needs the cloud computing, the cloud computing increases value of the big data. It researched functions and position of the three technologies in security of coal mine safety production combining with development course of construction of coal mine integrated automation, and proposed relations of the three technologies in security of coal mine safety production: the Internet of Things is technical framework and roadmap of construction of each subsystem of coal mine, the big data is product of construction of Internet of Tings of mine, the cloud computing is technical means for treatment and utilization of the big data. It indicated that monitoring and control system of coal mine safety production based on Internet of Things, big data and cloud computing would be a monitoring and control system with active mode, multi-parameter fusion and pre-warning function, which can effectively improve level of coal mine safety production.
