摘要
讨论了船舶动力装置凝给水系统的故障机理、故障模式和故障诊断方法,着重介绍了故障诊断半实物仿真试验系统的软、硬件设计。该仿真试验系统采用神经网络和规则诊断相结合的复合诊断方法,软件采用VC6.0与MATLAB6.5混合编程,通过半实物故障仿真平台,实现在线仿真和试验。
A study on the fault diagnosis of condensate feed water system about power plant using artificial neural networks is present in this paper. The hardware and software design of the semi-physical simulation system is discussed. A＂ new method for fault diagnosis based on neural network and logic reasoning is introduced. The programs are designed by VC language and MATLAB language. Finally, an on-line simulation and debugging of the semi-physical system is given.
