Abstract
A transceiver, which is included in a node, has at least one circuit. The at least one circuit includes an activation signal detection unit configured to detect identification information of an activation signa transmitted by another node to the on-board communication line. The node is connected to an on-board communication line as one of multiple nodes. Each of the multiple nodes is configured to transmit, to the on-board communication line, the activation signal that includes the identification information for identifying own node. The transceiver is configured to be activated when the identification information detected by the activation signal detection unit corresponds to own node.
Claims13
A transceiver, which is included in a node connected to an on-board communication line as one of multiple nodes, the transceiver comprising
- at least one circuit including an activation signal detection unit configured to detect identification information of an activation signal, which is transmitted by another one of the multiple nodes to the on-board communication line,
- wherein
- each of the multiple nodes is configured to transmit, to the on-board communication line, the activation signal that includes the identification information for identifying own node, and
- the transceiver is configured to be activated when the identification information detected by the activation signal detection unit corresponds to own node.
A communication system comprising
- a first communication device and a second communication device, which are connected to an on-board ethernet communication line as multiple nodes,
- wherein
- the first communication device includes an activation signal detection unit configured to detect identification information of an activation signal received from the on-board ethernet communication line,
- each of the multiple nodes is configured to transmit, to the on-board ethernet communication line, the activation signal that includes the identification information for identifying own node,
- the first communication device is configured to be activated when the detected identification information corresponds to the first communication device and then transmit a notification indicating activation of the first communication device to the second communication device, and
- the second communication device is configured to be activated when an activation message is received from the on-board ethernet communication line after receiving, from the first communication device, the notification indicating activation of the first communication device.
A method for activating a transceiver connected to an on-board communication line, the method comprising:
- receiving an activation signal from the on-board communication line, the activation signal having identification information for identifying one of multiple nodes connected to the on-board communication line;
- detecting the identification information of the received activation signal;
- and
- activating the transceiver in response to the detected identification information corresponding to own node.
