Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a radio communication system which can appropriately perform information communication between a master radio unit and a plurality of slave radio units.SOLUTION: In the radio communication system, a master radio unit R00 which becomes a start point successively transmits forward message data to each slave radio unit, as a radio unit in which each slave radio unit becomes an end point. Also, the slave radio unit, which becomes the end point of forward message data reception from the master radio unit R00, is operated next, as a radio unit which becomes the start point, transmits return message data to the master radio unit R00, as a radio unit in which the master radio unit R00 becomes the end point. When there is a slave radio unit which does not receive the return message data after transmitting forward message data, the master radio unit R00 performs retrial processing to transmit forward message data again to the slave radio unit, on condition that a lapse period from the transmission of the forward message data to the slave radio unit exceeds a predetermined restriction period.SELECTED DRAWING: Figure 1
【課題】親無線機と複数の子無線機との間での情報通信を適切に行うことができる無線通信システムを提供する。【解決手段】無線通信システムにおいて、始点となる親無線機R00は、子無線機の夫々を終点となる無線機として、子無線機に向けて往信用のデータを順次送信し、及び、親無線機R00から往信用のデータを受信した終点となる子無線機は次に、自身が始点となる無線機として動作して、親無線機R00を終点となる無線機として親無線機R00に向けて返信用のデータを送信し、親無線機R00は、往信用のデータを送信した後に未だ返信用のデータを受信していない子無線機があるとき、その子無線機に向けて往信用のデータを送信してからの経過期間が所定の制限期間を超過したことを条件として、その子無線機に向けて往信用のデータを再び送信するリトライ処理を行う。【選択図】図1 |
