Abstract


The developed computer status monitoring and fault diagnosis system is suitable for all types of large turbine generator , centrifugal compressor unit Rotating Machinery . Equipment condition monitoring and fault diagnosis through mastery of technical equipment and run basic demolished state judge about the error or fault causes and forecast the future , in order to identify the necessary measures . This system is under the Windows interface condition monitoring and fault diagnosis system , which support data acquisition card PCL 1800 , you can complete the vibration signal data acquisition and FFT power spectrum, cepstrum , time-frequency spectral array and coherence function analysis analysis , trend analysis, the axis orbit monitoring and fault diagnosis . The data can be converted into a variety of corresponding Graph . This paper describes the building blocks of the system and its functions . It can be widely used in electric power, petrochemical , metallurgy , automobiles and shipbuilding and other important sectors of the national economy , unit condition parameters monitoring analysis and troubleshooting . You can work instead of a dedicated signal processor . This paper discusses the application of network communication technology in large - scale rotating machinery monitoring and fault diagnosis system . Windows interface , the system , the use of Visual C WinSock technology , multi-threaded TCP server architecture mode ( client / server mode) , to achieve a shared LAN rotating machinery vibration signals to achieve a distributed diagnostic mode ( DMDS ) of the design requirements. Application software development tools, Visual C as a development tool , to run under Windows . Software interface designed to meet the needs of most users , and strive intuitive popular glance . The system has been successfully used in Jinxi Petrochemical Company of China National Petroleum Corporation .
