Title (EN) COMMUNICATIONS DEVICE AND COMMUNICATIONS METHOD
(FR) DISPOSITIF ET METHODE DE COMMUNICATION
Abstract:
(EN) A communications device 100, which performs data communication, includes an AC cycle sensor 30 which is connected to a power line 106 supplied with an a.c. voltage and generates a synchronous signal SS at timing of an a.c. voltage waveform AC of the power line 106; a data communicator 10 for performing data communication; and a communications controller 20 which performs communication of a control signal including information showing at least one of a communications device and a communications standard and controls the data communicator 10l. When the a.c. voltage supplied to the power line 106 is an N-phase and when the cycle of the a.c. voltage waveform is T, data communication to be performed in a communication period subsequent to the period is controlled on the basis of the control signal included in the period of T/2M on condition that M is a natural multiple of N.
(FR) L'invention concerne un dispositif de communication (100) qui effectue une communication de données. Ce dispositif (100) comprend un capteur de cycle AC (30) qui est relié à une ligne d'alimentation (106) alimentée par une tension AC et générant un signal synchrone (SS) à la synchronisation d'un signal de tension AC de la ligne d'alimentation (106); un dispositif de communication de données (10) pour effectuer une communication de données; et un contrôleur de communication (20) qui communique un signal de contrôle comprenant des informations indiquant au moins un dispositif de communication et une norme de communication, et contrôlant le dispositif de communication de données (101). Lorsque la tension AC fournie à la ligne d'alimentation (106) est en phase N, et lorsque le cycle du signal de tension AC est T, une communication de données à effectuer dans une période de communication subséquente à la période susmentionnée est contrôlée en fonction du signal de contrôle compris dans la période de T/2M à la condition que M soit un multiple naturel de N.
