<p>Disclosed is a technique capable of rataining communications between a radio device control device and radio devices. A division-assignment unit (1a) of the radio device control device (1) divides the information region of a frame for transmitting/receiving information to/from daisy-chained radio devices (2, 3, ···), and assigns the divided regions to the radio devices (2, 3, ···). A transmission unit (1b) transmits the address information of the information region, which is assigned to the radio devices (2, 3, ···) by the division-assignment unit (1a), to the radio devices (2, 3, ···). The receiving unit (2a) of the radio device (2) receives the frame from the radio device control device (1) or the radio device (2). On the basis of the positional information contained in the received frame, a position recognizing unit (2b) recognizes its own daisy-chained position. An acquisition unit (2c) refers to the frame on the basis of its own connected position recognized by the position recognizing unit (2b), and acquires the address information of the information region of the frame for transmitting/receiving the information to/from the radio device control device (1).</p> |
