资料介绍

甚高频通信系统是目前在飞机上应用最为广泛也是最为重要的无线电通信设备。对于其中的接收电路而言只要电路中相关电子元件出了故障就可能导致接收机的接收灵敏度变差、有杂音、无声等故障现象,影响飞机的正常通信,严重时可能导致飞行事故。因此,迅速地诊断出相应的故障元件就成了关键的任务。在总结前人成果的基础上,本文提出了以虚拟仪器为平台,使用神经网络算法设计出故障诊断系统来对接收电路故障元件进行诊断并最终达到了经济性、快速性和可靠性的效果。

VHF communication system is the most widely used on the plane and the most important wireless communication equipment. For the receiver circuit, related electronic component of it failing to work may result in fault performance in decline of receiver sensitivity,having-souffle or silence and so on,and influence the formal communication of the plane and even may lead to serious flight accident. Thus, rapid diagnosis of the related fault component has become a key task. In this paper, on the basis of previous results, under the virtual instrument platform, neural network algorithm is used to design a fault diagnosis system and diagnose the fault component in receiver circuit. Finally, it has achieved the economic,rapid and rel...
