In order to solve the problems of inaccurate vibration signal and difficult j udgment on faulty reason existed in current on-line monitoring system of main fan used in coal mine,a re-mote fault diagnosis system for main fan was developed,composed of fan monitoring sub-station, mining area branch station and remote center of predictive maintenance.In this paper,the design and implementation of main fan monitoring sub-station were introduced,including functional module structure of sub-station,monitoring parameters and hardware selection.The multithread design process and steps to realize the remote communication were analyzed.The practice showed that the sub-station could provide complete and accurate data for remote predictive maintenance on main fan,thus increase diagnosis accuracy.
