Design Of Condition Monitoring, Fault Diagnosis And Local Net System For Heavy Rotary Machine

The condition monitoring and fault diagnosis system for larger rotary machinery is applied to all kinds of larger rotary machinery such as Stirling engine. The condition monitoring and fault diagnosis system can give the causes of all faults and abnormalities and also gives the opposite measures by getting the condition parameters of machineries in the past or nowadays. The system is vibration signal processing system in windows. It has the functions of collecting vibration signals > power spectrum > cepstrum and transfer function analysis and so on with the PCL₁800. At the same time, the system can convert the data into the corresponding graph. This book introduces detailedly this system's components and their functions. It can be used largely in the fields of electrical system, oil and chemistry company, refine industry, automobile and the ship manufacturing etc for testing and analyzing of the vibration signals.The application of network communications technology in On-line Monitoring and Fault Diagnosis System of Large Unit Rotary Machine is studied in this paper. Under the interface of Windows, using technology of Visual C++ and multi-thread concurrent TCP server (Client/Server architecture), the monitored signals of rotary machine have been shared in local area network (LAN), and the requirement of Distributed Monitoring and Diagnosis System (DMDS) has been realized.This system software is programmed with the advanced programming language Visual C++ and runs in the window system. The design of the software interface can meet the demands of most users. The interface is friendly and popular common.
