Fault Testing And Diagnosis System Of Armored Vehicle Based On Information Fusion Technology

摘要

This paper introduces a fault testing and diagnosissystem of bearing in armored vehicle. It can realize real-time testing and precise fault diagnosis of bearing on vehicle chassis. In the hardware, it adopts PCL1800 data acquisition card to acquire sample data and send to the software. In the software, we compile fault testing and diagnosis system of bearing in armored vehicle on a portable computer, its core diagnostic method based on virtual instrument and multi-sensor information fusion technology. Virtual testing subsystem has various functions, including on-line data acquiring, signal displaying, different kinds of signals analyzing and data management. It only monitors the status of bearing and warning alarm. The further work to judge the type and the severity factor of the faults lies on fault diagnosis subsystem based on neural network information fusion technology.
