The invention relates to the technical field of aircraft fault detection and discloses a real-time monitoring system for aircraft fault detection. The system can monitor the current infrared thermogram, audio signal and vibration frequency of an electrical device and compare the current infrared thermogram, audio signal and vibration frequency with the normal infrared thermogram, audio curve and vibration frequency, when the electrical device is abnormal, the infrared thermogram, the audio signal and the vibration frequency are obviously changed, abnormity can be obviously found through comparison, then an alarm is given in time to remind a worker, the infrared thermogram, the audio signal and the vibration frequency are used for monitoring the electrical device at the same time, the monitoring is more accurate, the fault position of the electrical device can be accurately positioned, the heavy work of complete maintenance is avoided, the fault position can be directly maintained, thedesign is novel, and the system has the advantages that an electrical device on an airplane can be monitored in real time, and the fault position on the electrical device can be accurately positioned.
本发明涉及飞机故障检测技术领域,且公开了一种用于飞机故障检测的实时监控系统,该系统能够监测电气装置当前的红外热图、音频信号和振动频率,并与正常的红外热图、音频曲线和振动频率进行对比,当电气装置发生异常时,红外热图、音频信号和振动频率均会发生明显的变化,通过对比能够明显的发现异常,进而及时的进行告警,以提醒工作人员,并且,利用红外热图、音频信号和振动频率同时对电气装置进行监测,监测会更加的准确,能够对电气装置的故障位置进行精确定位,免去了全部检修的繁重工作,可以直接对故障处进行维修,本发明设计新颖,具有能够对飞机上的电气装置实时监测、能够准确定位电气装置上故障的发生位置的优点。
