The development and innovative direction of train control system

In this paper, the development and systematic frame of train control system technique are introduced at first, and the importance of patent innovation about train control system technique is pointed out. Then, the ground equipment and on-board equipment, which are the main parts of train control system, are divided into more technique branches for further study. The patent applications about the above technique branches are searched and analyzed, and the same time, the developing status of the above technique branches are summed up in detail and compared with some graphs. At last, some innovative direction for train control system in above technique branches are proposed.
