Abstract

The invention relates to a ONU device, a PON-CAN bus architecture and a robot system. The ONU device comprises a CAN adapter, an MCU module connected with the CAN adapter, and an optical transceiver connected with the MCU module. The optical transceiver is connected to an optical fiber bus in the PON-CAN bus architecture; The CAN adapter is used for providing a CAN interface of the ONU equipment;And the MCU module is used for performing mutual conversion between the CAN message and the message transmitted on the optical fiber bus.

Description

technical field [0001] The present disclosure relates to the field of communication control, in particular, to an ONU device, 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, the maximum transmission rate of the CAN bus is 1Mbps, and as the distance between the two nodes increases, the communication rate of the CAN bus will slow down, which limits the number of nodes connected to the CAN bus. [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 amount of movement, ...
