基于多信号模型的装甲车辆电源系统诊断策略

针对装甲车辆电源系统模块失效和信号失效不统一的特点,提出了一种多信号模型的改进方法,在此基础上,通过电源系统故障模式影响分析,建立了电源系统测试性模型。基于故障熵理论,利用诊断信息量和费用优化的启发式函数,确立了系统的诊断策略。计算结果表明:该方法对诊断策略的优化是有效的。该方法对装甲车辆电源系统诊断策略的研究具有一定参考意义。

Armored Vehicle Power System Diagnosis Strategy Based on Multi-signal Model

Aiming at the character of armored vehicle power system that the signal failure relating to the functional cell is not unified with the module failure,the multi-signal model is improved.On this basis,with the failure mode effect analysis of power system,the armored vehicle power system multi-signal model is designed.In virtue of failure entropy theory,with the heuristic function of optimized diagnosis information quantity and cost,the diagnosis strategy is established.The calculation result shows the effect...
