چکیده
The balise is an important component in train operation control system fulfilling the task of Ground-Train Point-Mode data transmission. This paper presents a finite element based method for researching the electromagnetic interaction process of balise up-link data transmission with respect to the basic theoretical level. Based on the basic structure and working principle of balise information transmission system, the model of balise up-link data transmission is built by employing the finite element method. Through simulation, the overall electromagnetic field distribution of this interaction process is obtained. By means of contrast verification using simulation results and practical data, the validity and credibility of this FEM based model is proved in two perspectives, which will provide theoretical foundations for further researches in terms of balise information transmission.
