Method and system for monitoring vibration of reactor equipment element

The invention discloses a reactor equipment element vibration monitoring method and system, and the method comprises the steps: installing an acceleration sensor at a measurement point of primary loop main equipment, collecting vibration signals of a loosening part and reactor internals in real time, processing the vibration signals through a pre-amplifier and a data collector, and transmitting the processed vibration signals to a monitoring center; the vibration signals are transmitted to an industrial personal computer for processing through a network switch connected to a whole plant clock network, the industrial personal computer analyzes and processes the vibration signals after clock synchronization, and vibration abnormity of the loose parts and vibration abnormity of reactor internals are diagnosed; if the diagnosis result is that one or two of the vibration of the loose part and the vibration of the reactor internals are abnormal and alarm is needed, alarm suppression state judgment is carried out; i
