摘 要: 针对飞机电源系统故障互相关联的特点,应用多传感器数据融合技术,将多种故障报警信息经证据理论决策,得出较准确的唯一故障类型。在分析了飞机直流电源系统故障现象及原因后,建立了电源系统故障诊断的基本概率赋值表。通过对基本概率赋值的计算,比较了3种融合理论方法的准确性;最后,通过实验验证了3种故障类型推理方法的正确性。 Aiming at the characteristic of the aircraft power system fault relating with each other,multiple failure alerting information is fused by The D-S theory to get the accurate failure.Based on analysis of the aircraft DC power system failure reasons,the basic probability table of a power system faults diagnosis is found.By the calculation of basic probability assignment,the accuracy of three methods is compared.Finally,the experiments are done to verify three fault types inference methods.
