Adaptive Threshold Setting Method for Layer-count in Penetration Fuse

doi:10.3969/j.issn.1000-1093.2020.09.008

Abstract

Abstract: At present，the layer-count algorithm of penetration fuse usually uses one or more fixed thresholds to judge the target layer. The setting of threshold usually depends on the prior data. And there is no such a threshold which can fit all test conditions. For this problem， an adaptive threshold layer-count algorithm is proposed based on the fusion signal algorithm. The proposed algorithm uses the sensor signals collected by fuse to calculate the decision threshold of the next target in real time and online. Then the current number of layers is identified according to the calculated threshold. The simulated results show that the proposed algorithm can give the layer identification signal correctly under different test conditions compared with the fixed threshold algorithm.And the layer identification signal given by the proposed algorithm is in good agreement with the time recorded by high-speed camera in the actual test.
