摘要:为了使电路故障诊断系统更加智能化、高效化,将基于模型诊断的故障诊断技术应用在智能消防小车电路中。根据小车的系统行为信息对小车进行建模,利用串口模块将描述文件在线输入到计算机中,再根据IsDS算法以及带有终止节点的CSSE?tree算法调用MiniSAT求解器求解诊断结果。实验表明,该系统能够迅速指示故障元件,诊断效率较高,具有较好的应用前景。

Abstract: In order to make the circuit fault diagnosis system more intelligent and efficient, the fault diagnosis technology based on model is applied to the circuit of intelligent fire truck. The fire truck was modeled according to the system behavior information. The serial module is used to import the description file into the computer online, and then the MiniSAT solver based on IsDS algorithm and CSSE?tree algorithm with termination node is called to solve the diagnosis results. The experimental results show that the system can quickly indicate the fault component, and has high diagnostic efficiency and good application prospect.

Keywords: model?based diagnosis; MinSAT solver; circuit fault diagnosis system; serial module

常见的电路故障诊断方法是技术人员利用仪表结合自身所学的知识及积累的诊断经验对电路进行一路一路的测试,最终确定故障元件。该方法诊断效率低下,而且要求对电路的工作原理有一定的了解。基于模型诊断技术利用电路元件之间的连接关系建立系统模型,如果观测到
