摘　　要：对矿用动态轻轨衡的关键技术进行了研究,提出了恶劣矿山环境下高精度称重的方法。该方法采取轮计重方式,无需额外安装红外对射探测器或独立的方向传感器,而是交错安装称重传感器,对矿车运行方向进行判断。在提取出有效计重信号后,结合经验模态分解方法,进行矿车质量计算。试验表明,该方法实现了高精度测量。The key technologies of mine-used dynamic light-railed weigher are studied,and a method is proposed to achieve high weighing precision in tough mining environments.In the method,the tramcar is weighted as the sum of weight of all wheels,and the steering direction of tramcars is judged through staggered mounted weighting sensors instead of additional photoelectric beam detectors or separate sensors.The useful weighting signal is collected and used for calculating the mass of the tramcar by empirical mode decomposition（EMD） method.Experimental results show that the method achieves high precision measurement.
