Fault Diagnosis Based on Vibration Signal of Rotating Machinery

摘要

Rotation machine plays an important role in the production of electric power, chemical industry etc... In the methods of fault diagnosis, the selection of the Pc and Pm of common genetic algorithm will influence its convergence and is easy to be trapped into the local optimum to propose an adaptive genetic algorithm of the fault diagnosis; and in the implementation of system function, it takes the S3C2410 chip as the core of the microprocessor and uses the embedded Linux as the operating system as the software development platform. In this paper, it introduces the design of the various parts of the system hardware in details, achieves the Boot Loader through combination of the hardware platform and successfully transplants the Linux operating system and builds a root file system, with the combination of the Linux operating system platform, it achieves the LCD frame buffer display device frame buffer, touchscreen A/D converter and development of Ethernet driver program, and the develops the data acquisition, wavelet packet analysis and Ethernet driver program etc. based on the system functions.
