Abstract


In this thesis, the online monitoring and fault diagnosis system based on LabVIEW fan. The system hardware consists of signal filtering, resonance demodulation and data acquisition card design, software design in modern signal processing platform LabVIEW programming signal storage, signal analysis, fault diagnosis, fault alarm, time domain and frequency domain waveform display. For the fan vibration signal mechanism, combined with fault diagnosis technology, dimensionless parameters in time domain analysis, spectral analysis, the inverted spectrum analysis, envelope analysis and wavelet analysis, fault diagnosis expert system design, signal analysis module provides timely judge equipment condition given the variety of fault information. Monitoring system in order to extract the wind turbine gearbox, bearing the initial failure information in hardware using the resonance demodulation technique, wavelet analysis software, are two ways to extract the gear, bearing the initial failure tiny shock results, each other verification, to further improve the accuracy of fault diagnosis. Gear box and bearings of large-scale wind turbines can accurately detect the initial failure, clearly show the parts early fault features correctly and effectively reveal the fault occurrence and development. Online monitoring and fault diagnosis system based on LabVIEW wind turbine research has been successfully applied to the online monitoring system for chemical plant fan, various functions have been tested and successfully detected the fan to accelerate the initial failure of the gearbox. Reasonably formulate the results of successful applications for the enterprise equipment maintenance plan, improve equipment operation and management level, the ultimate goal of laying the foundation equipment predictive maintenance. The successful application of the fan-line monitoring and fault diagnosis system based on LabVIEW for enterprises bring the following benefits: (1) reduction of maintenance personnel and costs; (2) state management of the wind turbine equipment, corrective maintenance, planned maintenance and predictive maintenance; (3) early detection of hidden faults, reduce the fan downtime and prevent unexpected incidents, and improve productivity. (4) when found hidden faults can not stop, can guide the operator to control the fan use to minimize the loss. (5) reasonably predict the life of the fan, the mechanical equipment in extended active duty in ensuring quality production case. Signal conditioning instrument designed this system with independent intellectual property rights, has been patented.
