一种井下人员乘车识别与定位方法
A method for identifying and locating underground personnel in a vehicle
摘要
Abstract
Most of the existing accurate positioning systems for underground personnel are based on UWB positioning technology and adopt the layout mode of personnel positioning card+positioning substation,which can achieve centimeter-level high-precision positioning without occlusion.When underground personnel travel,it is difficult to achieve accurate positioning of passengers due to the influence of a large range of metal occlusion of mining vehicles and dense factors in the compartment on positioning accuracy.To address the above issues,a method for identifying and locating underground personnel in a vehicle is designed.The status of per-sonnel in a vehicle is recognized through multiple information such as vehicle speed monitoring,positioning card posture,and in-vehicle distance measurement.While the onboard positioning card measures distance with the positioning substation in the tunnel,the information of passengers in a vehicle is transmitted to the positioning substation through message reuse,the positioning substa-tion uploads passenger information to the ground data center through the mine ring network.The test results show that the method has a high accuracy in identifying personnel in a vehicle,and the location information of passengers is synchronized with the vehicle position,which can effectively solve the positioning problem of underground personnel boarding.关键词
