基于CAN总线的分布式智能节点的设计

The design of distributed intelligent node based on CAN bus

介绍了一种基于CAN总线的分布式智能节点的设计。系统由上位管理机、CAN总线接口适配卡和多个智能节点组成,节点数量可根据需要增减。该系统不仅可以实现对节点数据的实时采集、显示,同时,通过上位机对多个节点上的测控模块设定各控制点的控制参数,实现了对各测控节点的实时控制。结果表明,CAN总线在通信能力、可靠性和实时性等方面具有明显的优势。

The paper introduces the design of distributed intelligent node based on CAN bus. The system is composed of PC, CAN bus adapter and other intelligent nodes. It can real-time collect and display the data of node. Simultaneous, it can control each node by setup parameter of each control place via PC. It can be proved that CAN bus has an obvious advantage at com- munications ability, reliability and real-time ability etc.
