PON NETWORK, METHOD AND APPARATUS USED FOR PON NETWORK, AND ROBOT SYSTEM

摘要

A PON network, a method and apparatus used for the PON network, and a robot system. The PON network comprises an OLT and an ONU connected to the OLT, and the PON network and a CAN bus constitutes a PON-CAN bus architecture, wherein the OLT and the ONU comprise a protocol layer of a field bus protocol to enable the OLT to be a network management control master node of the field bus protocol and enable each ONU to be a network management control slave node of the field bus protocol, so as to operate an application based on the field bus protocol; and the OLT as an network management control master device further comprises a first state machine module and a first message bus layer module, and the ONU as an network management control slave device further comprises a second state machine module and a second message bus layer module, wherein the OLT and the ONU mutually subscribe to message topics to implement message communication between the OLT and the ONU.
