| Abstract: | Vibration signal and its characteristic information in the course of running of feed water pump are significant for the state monitoring of the feed water pump system.The online monitoring system for the running state of feed water pump takes DSP(digital signal processor) as the core,and adopts the monitoring method which relies mainly on vibration monitoring and partly on course quantity monitoring.The operation principle of the online monitoring system for the running state of feed water pump is introduced,and the implementation method of FIR DF algorithm and FFT algorithm on DSP is analysed.A good result through using the system in Xiangtan power plant of Hunan province is obtained.This has important directive significance to diagnose and overhaul the complement machines. |
