基于D-S证据理论的多传感器燃爆判别方法
Multisensor Explosion Discrimination Method Based on D-S Evidence Theory
摘要
Abstract
The key to measuring the delay period and calculating the parameters of explosion point is to accurately distinguish the state of explosion.Due to the poor discriminant effect of single sensor and conflicting discriminant results among multiple sensors,D-S(Dempster-Shafer)evidence theory is used to jointly discriminate conflicting evidences.Firstly,according to the explosion characteristics of energetic materials and the test principle of explosion point,a temperature and sound-based joint discrimination device is designed.Based on the experimental data,the temperature eigenvalue is extracted by using the model fitting method,with the maximum value of sound signal as sound eigenvalue.Secondly,basic probability assignment(BPA)function is solved by Sigmoid model,and the value of the BPA function with potential conflicts is preprocessed by reliability entropy.Finally,D-S evidence theory is used to make joint judge-ments of explosion state.The experimental results show that the robustness of the experimental device and the confidence probability of state discrimination are effectively improved,with explosion discrimination accuracy of 96.5%,which is better than the discriminatory effect of single sensor,such as temperature and sound sensor.关键词
