摘要
提出基于Lon Works现场总线的大射电望远镜索网反射面节点控制方法,节点控制器采用嵌入式技术设计。该系统使用32位ARM微处理器AT91RM9200与神经元芯片Neuron3120xx,以主从CPU的形式构成节点控制器,实现对现场数据的处理和电动机的控制。系统具有网络节点分布灵活、节点容量大、控制实时性好,能很好地满足大射电望远镜索网反射面的节点控制要求。
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 AqglRM9200 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.
