Title (EN) COMMUNICATION SYSTEM AND COMMUNICATION DEVICE
(FR) SYSTÈME ET DISPOSITIF DE COMMUNICATION
(JA) 通信システムおよび通信装置
Abstract:
(EN) A slave device uses a superimposed signal, i.e. a second protocol signal superimposed on a transmission signal transmitted from a master device, to communicate with another slave device. The slave devices are each provided with a request unit which transmits, to the master device, in accordance with a second protocol, a reservation request including a unique identifier. The master device is provided with: an acquisition unit which receives the reservation requests; and a reservation unit which transmits reservation data in a transmission band of the transmission signal, in accordance with a first protocol. The reservation data prohibits the transmission of return data on a subsequent return band in the transmission signal, thereby reserving said return band for communication between the slave devices. The reservation unit is configured such that, when a reservation request is received by the acquisition unit, the reservation data is transmitted as a response to the reservation request.
(FR) L'invention concerne un dispositif esclave qui utilise un signal de superposition, c.-à-d. un second signal de protocole superposé sur un signal d'émission transmis depuis un dispositif maître, afin de communiquer avec un autre dispositif esclave. Les dispositifs esclaves sont pourvus chacun d'une unité de demande qui transmet au dispositif maître, conformément à un second protocole, une demande de réservation comprenant un identifiant unique. Le dispositif maître est pourvu des éléments suivants : une unité d'acquisition qui reçoit les demandes de réservation ; et une unité de réservation qui transmet des données de réservation dans une bande de transmission du signal de transmission, conformément à un premier protocole. Les données de réservation interdisent la transmission de données de retour sur une bande de retour ultérieure dans le signal de transmission, réservant de ce fait ladite bande de retour pour une communication entre les dispositifs esclaves. L'unité de réservation est configurée de telle sorte que, quand une demande de réservation est reçue par l'unité d'acquisition, les données de réservation sont transmises en réaction à la demande de réservation.
(JA)  子機は、親機から送信される伝送信号に重畳される第2プロトコルの信号である重畳信号を用いて、他の子機と通信する。子機は、各々に固有の識別子を含む確保要求を第2プロトコルに従って親機へ送信する要求部を有する。親機は、確保要求を受信する取得部と、伝送信号の送信帯において確保データを第1プロトコルに従って送信する確保部とを有する。確保データは、伝送信号における次の返信帯での返送データの送信を禁止することにより、この返信帯を子機同士の通信用に確保するデータである。確保部は、取得部にて確保要求を受信すると、この確保要求への応答として確保データを送信するように構成されている。
