To extract a number of vibration data of key positions of the marine gas turbine within some frequency bands accurately in real time,a kind of all localization distributed vibration measuring system was designed.The system was composed of vibration transducers,all localization distributed vibration measuring devices,the marine host control system and the vibration spectrum analyzer.The all localization distributed vibration measuring device was based on the core processor GD32F405RGT6,which collected vibration signals by the vibration transducer and extracted the in-band data with the finite impulse response(FIR)filter.The result shows that the system is flexible,accurate extraction and stability.It can meet the requirements of actual application.
