Abstract: Considering the power supply and information receiving defects of the wireless multicenter acoustic emission monitoring system in Sandaozhuang open-pit mine,carriers out the optimizing study on monitoring power supply system and information transferring mode.According to the power supply requirement, mining site and weather factors,calculates the reasonable power of the solar panel; through the power supplysystem's two-stage research,optimization and scene experiments,proves that the integrated system of power supply and acoustic emission monitor operates stably,storage battery capacitance is matched with solar panel power, the power supply tentative design is reasonable;the integratedsystem's study, manufacture and application reduce monitors'labor input effectually, decrease work frequency of the staff and trucks, improve the production security, increase social benefit and potential economic benefit obviously.The information transferringmode's optimization resolves the difficulty that the monitoring center does not receive the long-distance or exceptional area monitoring information, increases the ground pressuremonitoring's real-time, precision, allsidedness.
