Abstract: In view of the heavy workload of manual patrol inspection,the untimely discovery of pipeline damage and the invisibility of management data in the air supply system of Dayingezhuang Gold Mine,sensors are installed at the key nodes of the air supply network to obtain wind pressure,velocity,flow and other air supply parameters.The ethernet ring network and wireless coverage network are arranged underground to realize the real-time upload of monitoring data.Based on the internet of things and big data analysis technology,the intelligent mine air supply monitoring system is constructed.The intelligent management of the air supply system of Dayingezhuang Gold Mine is realized by means of real-time on-line monitoring,historical data query,air supply energy consumption analysis,leakage detection and so on.
