Abstract: In order to improve the versatility of rotating machinery condition monitoring system, a novel monitoring system includes several proximity prolm signal data collecting subsystems, several accelerometer signal data collecting subsystems, a process variables data collecting subsystem, a communication controller, and a personal computer, The system data collecting and analyzing software installed in the personal computer is the main part of the system, According to the requirements of machinery monitoring applications, the user can flexibly configure the system as a portable off-line data collecting and analyzing system, a moving on-line monitoring system or an on-line monitoring system with various data sampling modes and data analyzing functions, All of the data collecting subsystem and the communication controller are DS80C320 single chip microprocessor based design with high speed, small size and low power assumption. The system improves greatly the flexibility of the rotating machinery condition monitoring systems. The system design, the hardware and software design, and the practical application results are discussed in detail.
