The invention belongs to the field of valve rod vibration prediction, and discloses a valve rod vibration prediction method suitable for a deep peak regulation working condition and a related system.The system can capture key vibration conditions possibly occurring in actual operation by obtaining valve rod vibration signals under the deep peak regulation working condition; and a real data basis is provided for subsequent analysis. According to the method, interference and noise in the vibration signals can be reduced through noise reduction processing, the quality and credibility of data are improved, and therefore the actual vibration condition of the valve rod of the valve can be reflected more accurately. According to the invention, through vibration frequency identification, the system can distinguish different frequency components in the vibration signal of the valve rod of the valve, which is helpful for understanding the characteristics and properties of vibration, so that subsequent analysis and pred
