METHOD SYSTEM AND COMPUTER DEVICE FOR PREDICTING A CAPACITY BASED ON KALMAN FILTER

摘要

An embodiment of the present invention provides a capacity prediction method, system and computer apparatus based on a Kalman filter, the method comprising: obtaining a capacity time sequence to be predicted; and determining a kinetic model for the capacity time sequence And extracting a state transition parameter and a process noise parameter of the dynamic model; and performing Kalman filter estimation on the capacity time sequence using the state transition parameter and the process noise parameter to generate at least one state characteristic signal Segmenting the capacity time sequence based on the at least one state characteristic signal and determining at least one corresponding segment point; and based on the at least one segment point determined in the capacity time sequence, And estimating the capacity at a future time. The technical solution of the present invention realizes an accurate prediction of the capacity increase and allows the maintenance personnel to easily establish a reasonable capacity expansion plan.
