基于故障树理论的特种车辆三防系统故障诊断

为解决三防系统发生故障或状态异常时，特种车辆的防护性能大幅降低，严重影响车内人员人身安全的问题，建立三防系统的故障树模型。通过深入分析三防系统的工作原理及常见故障，对故障树模型进行定量和定性分析，并完成结构重要度分析。结果表明：该方法能快速定位三防系统故障，有效缩短故障排除时间，提高维修效率。

Fault Diagnosis of Special Vehicle Three-defense System Based onFault Tree Theory

In order to solve the problem that the protection performance of special vehicles is greatly reduced when thethree-proof system fails or the state is abnormal, which seriously affects the personal safety of the personnel in the vehicle,a fault tree model of the three-proof system is established. Through in-depth analysis of the working principle and commonfaults of the three-proof system, quantitative and qualitative analysis of the fault tree model is performed, and the analysisof structural importance is completed. The results show that this method can quickly locate the faults of the three-proofsystem, effectively shorten the troubleshooting time and improve the maintenance efficiency.
