Design of standardized information management system for coal mine safety productio

In view of problems of single information management method, information input and output delay, and lack of mining and analysis of business data in current coal mine safety production information management system,a standardized information management system for coal mine safety production was designed. The system builds a virtual private network to directly serves all personnel and special services for safety production management;through a variety of smart terminals and PC web terminals, various processes of predetermined process are coordinated to obtain accurate information support from the private network, and the private network is fully responsible for the follow-up processing requirements; key functions of the private network are extended to a variety of smart terminals to achieve "4A" information management mode which enables anyone uses any terminal at any time and any place. The system uses Miracast protocol and WiFi network to perform multimedia content transmission, analysis, display, control and other operations on different multimedia terminals, so as to achieve multi-screen linkage system control. At the same time, the system introduces Apriori algorithm for association analysis, improves and optimizes the algorithm based on multi-dimensional and multi-layer characteristics of the accident hazard data, and establishes an automatic mining and analysis subsystem at the background of the system to realize multi-dimensional and multi-level mining analysis of accident hazards. The actual application results show that the system improves timeliness of business processing, improves the level of coal mine safety production management, and the level of intelligent handling of coal mine emergency response.
