Research on Identification Card Searcher Technology Based on UWB Technology
Aiming at the problem that the card reading substation or card reader of the precise positioning system for underground personnel in coal mines is fixed installation and the signal coverage has blind zones,a design scheme of multi-functional positioning identification card search instrument based on UWB wireless precision positioning technology combined with intelligent terminal technology is proposed.The scheme uses intelligent terminal wireless line control technology,UWB wireless positioning technology,intrinsically safe lithium battery management technology to realize the long-distance search of all identification cards in coal mines,thereby making up for the defects of blind area recognition of underground identification cards in coal mines,providing guarantee measures for the supervision of coal mining enterprise safety production and supervision departments,and personnel search after mine accidents,and improving the level of intelligent construction of coal mines.
