Abstract
To provide a gateway device capable of continuing communication in the event of an abnormality without a redundant configuration as a system. A gateway device 100 includes a plurality of transceivers 110, 112, and 114 connected to a plurality of communication buses 1, 2, and 3 in a one-to-one manner, and a switch element 50 that connects the two communication buses 1 and 2 having different priorities among the plurality of communication buses.
Claims11
A gateway device, comprising:
- a plurality of transceivers that are connected to a plurality of communication buses in a one-to-one manner;
- and
- at least one switch element that connects two communication buses having different priorities among the plurality of communication buses,
- wherein the plurality of communication buses include a first communication bus to which a first control device is connected and a second communication bus to which a second control device is connected,
- wherein the first communication bus has a higher priority than the second communication bus,
- wherein the plurality of transceivers include a first transceiver connected to the first communication bus and a second transceiver connected to the second communication bus, and
- wherein the at least one switch element is a switch element that connects the first communication bus and the second communication bus.
4 more elements
A gateway device, comprising:
- a plurality of transceivers that are connected to a plurality of communication buses in a one-to-one manner;
- at least one switch element that connects two communication buses having different priorities among the plurality of communication buses;
- a memory in which priorities of the plurality of communication buses are stored;
- and
- a processing device that is connected to each of the plurality of transceivers,
- wherein, when a situation in which data cannot be received from a first transceiver connected to a first bus included in the plurality of communication buses among the plurality of transceivers has continued for a predetermined time or more, a switch element that connects the first transceiver and a second transceiver connected to a second bus having a priority lower than the first bus among the plurality of switch elements is set to an ON state, the processing device is configured to output a sleep command to the first transceiver, and data transmitted to the first transceiver is transmitted to the second transceiver.
3 more elements
A gateway device, comprising:
- a plurality of transceivers that are connected to a plurality of communication buses in a one-to-one manner;
- at least one switch element that connects two communication buses having different priorities among the plurality of communication buses;
- a memory in which priorities of the plurality of communication buses are stored,
- wherein, when the priority of the second communication bus is the lowest among the priorities of the plurality of communication buses, the plurality of switch elements are configured to respectively connect at least one of the plurality of communication buses excluding the second communication bus and the second communication bus.
