| Zusammenfassung: | To provide a transmission path switching system that selects a transmission path suitable for both in-vehicle and ground stations.SOLUTION: A transmission path switching system includes: an in-vehicle station 1 installed in a train; a ground station 2 installed on the ground; and a plurality of transmission paths L1 to Lp for transmitting data between the in-vehicle station 1 and the ground station 2. The transmission path switching system evaluates communications on each of the plurality of transmission paths L1 to Lp using data sent from a transmitting side of either the in-vehicle station 1 or the ground station 2 and received at a receiving side through each of the plurality of transmission paths L1 to Lp. On the basis of the communication evaluation, a transmission path for the transmission side to transmit data is selected from among the plurality of transmission paths L1 to Lp.SELECTED DRAWING: Figure 1
【課題】車上局および地上局の双方にとって適切な伝送路を選択する伝送路切替システムを提供する。【解決手段】伝送路切替システムは、列車に搭載された車上局１と、地上に設置された地上局２と、車上局１と地上局２との間でデータを伝送するための複数の伝送路Ｌ１～Ｌｐと、を備える。当該伝送路切替システムは、車上局１および地上局２のうちの送信側から送信され複数の伝送路Ｌ１～Ｌｐのそれぞれを通して受信側で受信された各データを用いた複数の伝送路Ｌ１～Ｌｐの通信評価を行う。当該通信評価に基づいて、複数の伝送路Ｌ１～Ｌｐのうちから送信側がデータを送信するための伝送路が決定される。【選択図】図１ |
