In the research and development of safe operation detecting system of the tamping machine

two-level data fusion processing mechanism of heterogeneous multi-sensor based on concept lattice theory is presented.Two-level of data fusion model is established.In order to overcome the shortcomings of poor accuracy and anti-inteference of multi-sensor monitoring data while the tamping machine in harsh working environment

the support matrix and the optimal weighting is introduced into the first level.The second level applies fuzzy attribute fusion techniques on the decision level to enhance the intelligence level of the monitoring system.
