Abstract

The invention belongs to the field of plane structure health monitoring, and relates to a software-hardware integration system and a software-hardware integration method for multiple sensor monitoring techniques in plane structure health monitoring. According to the plane structure health monitoring system integration method, the used plane structure health monitoring system is divided into subsystems according to functions, the plane structure health monitoring subsystems are mutually connected through network equipment by using hardware interfaces, software interfaces of the plane structure health monitoring subsystems are standardized, the plane structure health monitoring subsystems are managed, and data generated from the plane structure health monitoring subsystems are processed and visualized. According to the device and the method, multiple sensors are uniformly scheduled, the data are fused, processed and managed, remote monitoring is achieved, and the monitoring efficiency and the level are greatly improved.

Description

technical field [0001] The invention belongs to the field of aircraft structure health monitoring, and relates to a software and hardware integration system and method for solving multiple sensor monitoring technologies in aircraft structure health monitoring. Background technique [0002] In the aircraft structural health monitoring system, a variety of sensor systems are often used to monitor the monitoring objects. These sensor systems include fiber Bragg grating FBG, piezoelectric PZT, acoustic emission AE, stress-strain SG, intelligent coating SC, etc. In the process of aircraft structural health monitoring, it is necessary to perform data fusion of various sensor data, discover and summarize the correlation between various sensor data, and then make more accurate diagnosis and evaluation results. The integration of multiple sensor systems is the basis of data fusion. It is necessary to design the framework of the integrated system, data flow model, etc. The integrated ...
