Abstract: With the use of ARM and DSP as the platform, a set of comprehensive on-line vibration monitoring system for marine power shaft system was developed for assuring its operation safety. The electric strain measurement, wireless telemetry and digital signal processing techniques were applied. The real-time monitoring of the operation status of the shaft system can be realized with this system. Some important parameters can be obtained on time so that the operation safety of the shaft system can be guaranteed. The monitoring system was verified by the testing on a diesel engine testing bench. Results of measurement showed that the shaft vibration monitoring system could achieve higher accuracy in monitoring.
