Research on the intelligently early warning of the mine safety based on the multi-sensor data fusion technology

the key to the intelligently early warning technology of underground mine hazards is the accurate and reliable data collected with multi-sensor timely and efficiently. In the paper, the hierarchical clustering algorithm is applied to realize the 3 hierarchical clustering application combined with the data type of hierarchical clustering and value of the security standards, in which the complementary of multi-source information is made full use of to shield its redundancy. And the application of coding technology of the definition of data frame deals wtih data transfer and optimization of transmission by events triggered, effectively improveing the accuracy and reliability of deviation data and emergency response data, to improve the efficiency of wireless sensor network data collection and transmission.
