The concept

characteristics of pulse production line is introduced

and the current application of pulse production line is reviewed. The factors influencing pulse production line and the necessity of state prediction are analyzed. Then

a method of state prediction based on Markov chain model is proposed. Based on Markov Chain forecast theory

the running states of pulse production line are classified. The state transition matrix is determined and the Markov forecast model is established. Last

the validity of the model is estimated.
