【摘要】 针对目前我国煤矿生产事故频发,工人生命安全得不到保障的严峻现实,提出了基于射频识别(RFID,Rad io Fre-quency Identification)技术和Z igBee无线通信技术的井下定位系统。结合控制中心数据库,实现了对矿工位置的跟踪和定位,并能够查询人员在过去一段时间内的工作路线,从而加强了对整个煤矿的实时管理。在事故发生后能够在最短时间内实现对被困人员的搜救,大大加强了矿工的安全保障。更多还原

【Abstract】 Aiming at the serious fact that in China,accidents in coal mine production happen very often,and the safety of miners is not reliably ensured,a wireless locating system based on RFID and ZigBee techniques is designed for under-pit use.This system,combined with the database in command center,is able to tell and track the minders’ positions,as well as plot the path line of the miners in a past period,hence reinforces the real-time management of the pit.When accidents happen,this system is also helpful for shortening the time on searching buried miners,increasing rescue efficiency,and making their safety more ensured.更多还原
