Research and application of upgrading and renovation of personnel positioning system in Xin'an Coal Mine
The personnel positioning system in coal mine underground is a high-end technology to strengthen the management of person-nel into the weill,improve life security,and promote coal mine safety production.The KJ251 personnel positioning system used by Xin'an Coal Mine was installed in 2011,using RFID positioning technology to achieve regional positioning.This technology has the charac-teristics of simple implementation and low system construction cost,with the advancement of intelligent underground coal mine,higher demand for personnel positioning has been put forward.Currently,there are mainly problems such as browser kernel versions,system central station software,and database architecture not meeting the current information development needs,unstable system data,and the lack of a unique card checking device in the system.Combined with the special working environment of coal mine,the personnel positio-ning system in coal mine underground can realize the functions of real-time monitoring,accurate positioning,track playback,manage-ment of checking on work attendance,report form inquiry,information network publishing,two-way communication,man-machine inter-action,emergency search and rescue,production scheduling,etc.to provide first-hand reliable decision-making real-time information for coal mine safety production and emergency rescue.
