| Abstract: | A node control method of LT main reflector is proposed,which is based on Lon Works field bus.Node controller adopts the embedded technology.32-bit ARM microprocessor AT91RM9200 and Neuron chip 3120xx are used in the system.The node controller is built in master-slave CPU mode to accomplish the field data processing and motor control.The system designed is characterized by flexibility in node distributing,large node capacity and better real-time control.It can meet the node control requirement of the reflector used in LT. |
