| The paper aims to periodically evaluate the state of TT&C equipment through the service life prediction technology to tap the potential use value of the equipment, reduce the risk of failure, and provide reference for the equipment update and maintenance. The characteristics of the TT&C equipment were analyzed, and the data-driven life prediction technology was selected. The life prediction method of TT&C equipment based on Weibull distribution was analyzed. Through the mathematical formula derivation, the solution method for estimating the parameters of the two-parameter Weibull distribution by the maximum likelihood estimation method was given. It provides a scientific reference for life prediction and reliability assessment of TT&C equipment. |
