    摘要:

    針對雷達等復雜大型電子裝備網(wǎng)絡(luò )系統的故障定位難、影響關(guān)系不清晰的問(wèn)題,采用了基于模糊神經(jīng)網(wǎng)絡(luò )的故障定位方法,提高了網(wǎng)絡(luò )故障定位的快速性與準確性:首先介紹了模糊隸屬度及模糊神經(jīng)元等理論,接著(zhù)基于模糊理論將網(wǎng)絡(luò )監測信息進(jìn)行模糊化處理,并利用神經(jīng)網(wǎng)絡(luò )模型對模糊后的信息進(jìn)行訓練與學(xué)習,參數訓練達到設置的期望誤差0.01;最后利用訓練好的模型對隨機抽取的2組網(wǎng)絡(luò )故障實(shí)例進(jìn)行了驗證,軟件執行單次診斷耗時(shí)3.5s;結果表明采用基于模糊神經(jīng)網(wǎng)絡(luò )的診斷方法,能夠較好解決網(wǎng)絡(luò )故障耦合復雜、故障現象與故障原因關(guān)系不清晰等難題,對網(wǎng)絡(luò )故障快速排除與恢復具有重要意義。

    Abstract:

    Aiming at the problems of difficult fault location and unclear influence relationship in complex large-scale electronic equipment network systems such as radar, a fault location method based on fuzzy neural network is adopted, which improves the speed and accuracy of network fault location. Firstly, the theory of fuzzy membership degree and fuzzy neuron is introduced, then the network monitoring information is fuzzified based on fuzzy theory, and the fuzzy information is trained and learned by using the neural network model. And the parameter training reach the set expected error of 0.01.Finally, the trained model is used to verify two groups of randomly selected network failure instances. It takes 3.5s for the software to perform a single diagnosis. The results show that the diagnosis method based on fuzzy neural network can better solve the problems of complex network fault coupling and unclear relationship between fault phenomenon and fault cause, which is of great significance to the rapid elimination and recovery of network faults.
