A mine's dynamic rail track scale with automatic motion direction judge

A mine's dynamic rail track scale is studied and some methods of both simple and effective are proposed in this paper. The way of wheel weight for tramcar weighing is put forward. The automatic motion direction judge of the tramcar could be achieved by the staggered installation of the weight sensors without additional infrared detectors or direction sensors. The wheel weight signal is collected and processed combined with empirical mode decomposition (EMD) method.
