Based On The Arm Processor, Portable Vibration Measurement And Analysis System Research And Design

The condition monitoring of Rotating machinery can reduce the cost of devices maintenance , keep the security of manufacture and increase the use of devices. The portable data collector and signal analyzer based on embedded system is an important part of the condition monitoring of Rotating machinery. The focus of the thesis is the software design of the portable data collector and signal analyzer.The thesis narrates the development trend of the portable data collector and signal analyzer. According to the new requirement of the modern condition monitoring of Rotating machinery , it brings forward a new function design and chooses a ARM-based software and hardware platform. The software system includes data acquirement, real-time analyse , device-examination , accessorial fault-diagnosis , system parameter setting and data management. The thesis mainly introduces the software design of the system . At last. it discusses the theory of expert system and the method of rotating machinery fault diagnosis.
