摘要
针对地下管廊中的人和物精确定位需求,结合管廊窄且长的特点,提出了一种适用于地下管廊定位的单基线二维定位算法。该算法以基于最大似然到达时间(TOA,Time of Arrival)定位算法为基础,通过将三个定位锚点等间隔一条直线地部署在管廊顶部,实现人和物在管廊平行切面的二维定位。文中既探讨了锚点之间的间隔大小和定位精度的关系,又研究了标签和锚点之间的距离对定位精度的影响,并通过Matlab仿真实验得出了几种最优锚点部署方案。理论和仿真分析证明该算法是有效和可行的。
Aiming at the precise positioning requirements of people and objects in the underground pipe gallery,combined with the narrow and long characteristics of the pipe gallery,a single-baseline two-dimensional positioning algorithm suitable for underground pipe gallery is proposed in this paper.Based on the maximum likelihood estimation(Time of Arrival)localization algorithm,the algorithm implements the two-dimensional positioning of human and object parallel sections of the pipe gallery by arranging the three positioning anchors in a straight line at the top of the pipe gallery.In this paper,the relationship between the size of the anchor points and the positioning accuracy is discussed.The influence between the tag and the anchor points is also studied.Several optimal anchor deployment schemes are obtained through Matlab simulation experiments.Theoretical and simulation analysis proves that the algorithm is effective and feasible.
