摘要
水面无人艇(USV)远程控制系统的可靠性,直接影响到USV航行安全.文中建立基于故障树与贝叶斯网络相结合的可靠性评估模型.基于USV远程控制系统各设备之间的故障关系构造相应的故障树模型;将远程控制系统故障树映射成贝叶斯网络,利用所构建的贝叶斯网络模型进行评估分析.通过实例分析表明:该模型可实现对故障的反向推理,找出影响系统可靠性的主要因素,计算出系统的可靠性.
The reliability of remote control system of surface unmanned boat(USV)directly affects the navigation safety of USV.In this paper,a reliability evaluation model based on fault tree and Bayesian network was established.Based on the fault relationship between devices of USV remote control system,the corresponding fault tree model was constructed.The fault tree of remote control system was mapped into Bayesian network.The Bayesian network model was used for evaluation and analysis.The example analysis shows that the model can realize the reverse reasoning of faults,find out the main factors affecting the reliability of the system and calculate the reliability of the system.
