Power supply controller, relay node device, wired ad-hoc network system, and power supply control method

摘要

A power supply controller includes a first port, a second port, and a controller. The first port is connected to a power supply device. The second port is connected to a first relay node device via a wired path. The controller performs control to supply power received from the power supply device from the second port to the first relay node device. The controller performs control to generate a power-on instruction frame for instructing the first relay node device started by receiving power supply to start power supply from a port included in the first relay node device to a second relay node device connected to the first relay node device via a wired path. The controller performs control to transmit the generated power-on instruction frame from the second port.

1. A power supply controller comprising:
a first port that is connected to a power supply device; a second port that is connected to a first relay node device via a wired path; and a controller that performs control to:
supply power received from the power supply device from the second port to the first relay node device;generate a power-on instruction frame for instructing the first relay node device to start power supply from a port included in the first relay node device to a second relay node device connected to the first relay node device via a wired path;transmit the generated power-on instruction frame from the second port to the first relay node device after starting the first relay node device by supplying the power to the first relay node device;receive, from the second port, a start notification frame of a started relay node device which started by the power supply from the second relay node device which received the power supply from the first relay node device, the first relay node device receiving the start notification frame from the started relay node device transferring the received start notification frame to the second port, the start notification frame including
pieces of data respectively indicating a transmission port number and a reception port number of the start notification frame,data indicating a number of hops until the start notification frame is received by the power supply controller, anda power supply line flag indicating whether an adjacent relay node device connected to the started relay node device via a wired path is started by the power supply from a port of the started relay node device which transmitted the start notification frame;generate first network identification data indicating a transmission route of a frame from the started relay node device which transmitted the start notification frame, to the power supply controller in accordance with the data indicating the transmission port number included in the received start notification frame;generate second network identification data indicating a transmission route from the power supply controller to the started relay node device which transmitted the start notification frame in accordance with the data indicating the reception port number included in the received start notification frame;store the generated second network identification data, and the data indicating the number of hops and the power supply line flag which are included in the received start notification frame in a routing management table for managing a route to the started relay node device which transmitted the start notification frame; andtransmit a start notification response frame including the generated first network identification data to the started relay node device which transmitted the start notification frame in accordance with the second network identification data.
