Abstract: Based on the analysis of hydroturbine vibration monitoring system, this paper puts forward to the vibration real-time monitoring and analysis of vibration signal processing software as the core, and with the sensors and output devices are connected by monitoring and analyzing system. And it carries on the design scheme, hardware configuration, software debugging analysis. The experiment shows that the system can intuitively know the unit running status, and to judge the common faults in the operation, with state prediction function.
