Abstract

A PON-CAN bus architecture and a robot system, the PON-CAN bus architecture comprising an optical fiber bus and a total information device connected to the optical fiber bus, the optical fiber bus being formed by interconnecting a plurality of asymmetric couplers; the symmetric couplers are configured to branch the next level network; the total information device is configured to perform communication interaction with the next level network through the optical fiber bus. The robotic system includes the PON-CAN bus architecture, and various terminal control systems and terminal sensing devicesof robots connected to the PON-CAN bus architecture.

Description

technical field [0001] The present disclosure relates to the field of communication control, in particular to a PON-CAN bus architecture and a robot system. Background technique [0002] CAN is the abbreviation of Controller Area Network. The characteristic of CAN bus is that there is no master-slave distinction in data communication. Any node can initiate data communication to any other (one or more) nodes without being affected by a single node. Node damage leads to bus paralysis effects. However, in the related art, the maximum transmission rate of the CAN bus is 1 Mbps, and as the distance between two nodes increases, the communication rate of the CAN bus will slow down, so that the number of nodes connected to the CAN bus is limited. [0003] With the development of science and technology, the scope of application of control systems continues to expand, and more and more nodes are controlled, such as robot systems, which have the characteristics of large amounts of mov...
