鉄道車両間の無線ネットワークにおけるデータ伝送

抄録

With development of information and communication technology, condition monitoring system for train vehicles has been improved recently. By monitoring the vehicles and quickly informing the train crew of vehicle’s condition data, it is expected to develop safety and stability of the train operation. However, some existing vehicles cannot install networks for transmitting the monitoring data, because it is difficult to lay new wired lines due to insufficient space. On the other hand, it is relativity easy to secure space for a wireless terminal. To choose this alternative, a wireless network to monitor the vehicles has to be constructed. In this paper, we propose a method of construction of an inter-vehicle network. Moreover we consider the sequences of data transmission for regular and urgent. Then, we implemented a prototype system using the proposed method and performed the test of the prototype for confirming functionality and evaluating the method.
