Abstract: Key problems as low level of standardization, integration, reliability and overall data utilization, which existed in application of large rotary machine condition monitoring and fault diagnosis system, were analyzed. To satisfy the requirements of high reliability, networking and intelligence of system, an intelligent-maintenance-unit (IMU) integrated with multi-parameter signals was presented. The magnifiers, filters, modulators, power suppliers and interface circuits were integrated into the unit. Controlled by embedded chip and Digital Signal Processing (DSP) chip, the IMU can complete data acquisition, processing, characteristics extraction, state recognition, fault diagnosis, data management and remote maintenance service etc. The IMU technology is a development trend of rotary machine monitoring-diagnosis system.

Key words: rotary machine, fault diagnosis, maintenance, intelligent unit, network
