Zusammenfassung:To perform radio communication using a reflection wave by a frame with communication quality secured even when an opening is generated on the frame.SOLUTION: A communication system for performing radio communication between a control device 1 and a communication apparatus 2 using a reflection wave by a frame comprises: the control device 1; the communication apparatus 2; and a relay apparatus 3 capable of performing radio communication using a direct wave with the control device 1 and the communication apparatus 2. The control device 1 comprises an opening detection unit for detecting that an opening has been generated on the frame; and a link control unit for transmitting a relay instruction to relay communication between the control device 1 and the communication apparatus 2 to the relay apparatus 3 when the opening detection unit detects that the opening has been generated. The relay apparatus 3 comprises: a link control unit for establishing a link with the communication apparatus 2 when receiving the relay instruction from the control device 1; and a relay unit for relaying the communication between the control device 1 and the communication apparatus 2.SELECTED DRAWING: Figure 3 【課題】筐体による反射波を用いて無線通信を行う際に、筐体に開口が生じた場合でも通信品質を担保する。【解決手段】制御装置1および通信機器2間で、筐体による反射波を用いて無線通信を行う通信システムは、制御装置1と、通信機器2と、制御装置1および通信機器2に対して直接波を用いた無線通信が可能な中継機器3を備える。制御装置1は、筐体に開口が生じたことを検知する開口検知部と、開口検知部によって開口が生じたことが検知されると、中継機器3に対して、制御装置1および通信機器2間の通信を中継する中継指示を送信するリンク制御部を備える。中継機器3は、制御装置1から中継指示を受信すると、通信機器2との間でリンクを確立するリンク制御部と、制御装置1および通信機器2間の通信を中継する中継部を備える。【選択図】図3
