Abstract: In order to improve the efficiency of power transmission line inspection, this paper fully considers various fac- tors that influence the running state of transmission lines, establishs the transmission line operation state model based on bayesian network data mining method, and it can make reasonable inspection plan through the forecast results. The SPSS Clementine simulation test show tht this model has higher accuracy.
