摘　　要：现有矿用人员精确定位系统大多基于UWB定位技术,采用人员定位卡+定位分站的布局模式,无遮挡情况下可实现厘米级的高精度定位;当井下人员乘车时,由于矿用车辆的大范围金属遮挡和车厢内人员的密集因素对定位精度的影响,难以实现乘车人员的精确定位。针对上述问题,设计1种井下人员乘车识别与定位方法,在车辆外部安装车载定位卡,同时车厢内安装接收头,通过车辆速度监测、定位卡姿态及车内测距等多信息进行人员乘车状态识别;在车载定位卡与巷道内定位分站测距的同时,通过消息复用将车内乘车人员信息透传给定位分站,定位分站通过矿井环网将乘车人员信息上传至地面数据中心。测试结果表明:该方法对人员乘车识别准确率极高,乘车人员位置信息与车辆位置同步,可有效解决井下人员乘车过程中的定位问题。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 personnel in a vehicle is recognized through multiple information such as vehicle speed monitoring,positioning card posture,and invehicle 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 substation 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.
