DISTANCE MEASURING SYSTEM
To provide a distance measuring system that can improve the communication performance of ranging communication.SOLUTION: Four outdoor anchors 11-14 for transmitting and receiving ranging signals in a UWB band are installed outside a passenger compartment and two indoor anchors 15 and 16 for transmitting and receiving ranging signals in the UWB band are installed in the passenger compartment. The operation order of the indoor anchors 15 and 16 is determined according to an outdoor anchor (any of 11-14) that has established outdoor ranging communication. For example, when outdoor ranging communication is completed at the outdoor anchor 13, the indoor anchor 16 and the outdoor anchor 15 are operated in this order in indoor ranging communication.SELECTED DRAWING: Figure 3
【課題】測距通信の通信性能の向上を可能にした距離測定システムを提供すること。【解決手段】車室外には、ＵＷＢ帯の測距信号を送受信する４つの車室外アンカー１１〜１４が設置され、車室内には、ＵＷＢ帯の測距信号を送受信する２つの車室内アンカー１５、１６が設置されている。室外測距通信が確立した車室外アンカー（１１〜１４のいずれか）に応じて、車室内アンカー１５、１６の動作順が決定される。例えば、車室外アンカー１３で室外測距通信が完了した場合には、室内測距通信において、車室内アンカー１６、車室内アンカー１５の順に動作される。【選択図】図３
