Data acquisition and processing for mine´s dynamic rail weight-bridge

In order to achieve high precision of weighing in harsh environments, a method of weighing for mine´s dynamic rail weight-bridge is presented in this paper. In this method, the tramcar is weighted by the way of wheel weight and the weight sensors are staggered. The useful weight signal is collected and extracted before it is computed for weighting combined with empirical mode decomposition (EMD) method. Experimental results show that this method could achieve the target of “accurate”, “fast” and “saving”.
