【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。
[Abstract]:A safety management system for regional positioning of underground personnel is designed by using Internet of things technology.In this system, the intelligent security identification card is used as the issuer of the coordinate position of the current mobile node, the wireless location base station as the receiver of the coordinate position of the mobile node, and the 3D coordinate position of the underground worker is located based on the intersection centroid location algorithm.The coordinate information collected by Ethernet is transmitted to the ground monitoring and dispatching center.The ground monitoring and dispatching center automatically records the relevant information of underground workers according to the information received, and automatically statistics and generates attendance report forms.The whole set of positioning system has a strong adaptability to environment, it can collect the environmental information and locate the staff. By comparing with the experimental results of traditional quadrilateral measurement method, it is found that the three-dimensional positioning algorithm based on intersection centroid has better localization effect.The error is smaller.
