Problems solved by technology

However, the use of acoustic positioning still has certain shortcomings. For example, the monitoring effect of acoustic positioning is poor, and it is also difficult to detect the specific location of the fault on the electrical device, and it is more susceptible to external interference, resulting in monitoring errors

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aircraft fault detection, in particular to a real-time monitoring system for aircraft fault detection. Background technique [0002] Aircraft refers to a heavier-than-air aircraft that has one or more engines to generate forward thrust or pull, and the fixed wings of the fuselage to generate lift, and fly in the atmosphere. Since the invention of the airplane, the airplane has increasingly become an indispensable tool of modern civilization. It has profoundly changed and influenced people's lives, and opened the history of people conquering the blue sky. [0003] With the development of the aviation industry, the aircraft has become an important means of transportation for people to travel. Due to its own particularity, the loss of life and property caused by each aircraft accident is extremely serious. According to civil aviation statistics, 10% of flight failures are caused by internal aircraft mechan...
