摘　　要：采用物联网技术设计了一套地下人员区域定位的安全管理系统。该系统采用智能安全识别卡作为当前移动节点坐标位置的发出者,无线定位基站作为移动节点坐标位置的接收者,基于交点质心定位算法定位地下工作人员的三维坐标位置,并通过以太网将采集到的坐标信息传输至地面监控调度中心。地面监控调度中心根据接收到的信息自动记录地下工作人员的相关信息,并自动统计生成考勤报表。整套定位系统环境适应度强,可实现对环境信息的采集和工作人员的定位,通过与传统的四边测量法实验结果进行对比,发现基于交点质心的三维空间定位算法定位效果更好,误差更小。A safety management system for underground staff regional positioning was designed by means of Internet ofThings technology.The intelligent security identification card is taken as the initiator of the current mobile node coordinate location in the system,and the wireless positioning base station is taken as the receiver of the mobile node coordinate position.Thethree-dimensional coordinate location of the underground staff is located on the basis of intersection centroid localization algorithm.The coordinate information acquired through Ethernet is transmitted to the ground monitoring and dispatching center.Theground monitoring and dispatching center records the relevant information of the underground staff automatically according to thereceived information,and analyzes and generates the attendance report automatically.The whole positioning system has strongenvironment adaptability,and can acquire the environment information and locate the staff.In comparison with the experimentalresult of the traditional four-side measurement method,it is found that the three-dimensional space localization algorithm basedon intersection centroid has better positioning effect and smaller error.
