PROBLEM TO BE SOLVED: To provide a technology for configuring a radio communication system by applying a wireless sensor network to a vehicle state monitoring system.SOLUTION: In a radio communication system 1 comprising a host device 20 mounted on a head vehicle 12, and a relay device 30 mounted on each of other vehicles 10, the host device 20 uses connection information for a train composition after coupling/decoupling to update a communication matrix, which is information as to whether direct communication is possible between devices, updates a route table of itself (the host device 20) according to the updated communication matrix. It also creates a route table of each relay device 30 and transmits the created route table to the corresponding relay device 30.SELECTED DRAWING: Figure 1

    【課題】ワイヤレスセンサネットワークを車両状態監視システムに適用して無線通信システムを構成するための技術を提供すること。【解決手段】先頭車両12に搭載されるホスト装置20と、他の各車両10に搭載される中継装置30とで構成される無線通信システム1において、ホスト装置20は、増解結後の編成についての連結情報を用いて、各装置間の直接通信の可否の情報である通信行列を更新し、更新した通信行列に従って、自装置(ホスト装置20)の経路表を更新するとともに、各中継装置30の経路表を作成し、作成した経路表を該当する中継装置30へ送信する。【選択図】図1
