Abstract： |
This invention relates to a system of bondage of intra-plate CAN bus capable of expanding in ring type and optical fabric system, belonging to power electron application technology field, characterized in that the control node comprises a main control node located on the main control plate with ring bus; fixing auxiliary control node located on the auxiliary control plate; a plurality of expanded control nodes located on the corresponding expanded control plate; each control node adopts optical fabric communication linked to link with bus, and the said control nodes form ring net in the order of label, bus reserves optical fabric CAN interface for the head node and end node of ring net, the two CAN interfaces expand segment CAN bus on the expanded control plate, and form expanding CAN bus ring net in the order of optical fabric, the control nodes of the expanding control plate is linking with the segment bus on each plate. The invention has the advantages of anti-interference ability and independence of nodes. |
