基于STM32和CAN总线的智能数据采集节点设计

摘要

Considering industrial control network demand for real-time data transmission, an intelligent data acquisition node design scheme based on STM32 (ARM 32-bit Cortex -M3 MCU) and CAN-bus was proposed, including the scheme for both hardware circuit and software design. The debugging operation proves its reliable communication among nodes and strong anti-interference capability.%针对工业控制网络对实时数据传输的需求,提出了一种基于CORTEX-M3内核32位ARM微处理器STM32的CAN总线智能数据采集节点设计方案.给出了节点的硬件电路和软件设计方案.经调试表明,各节点之间的通讯可靠,抗干扰能力强,达到预期设计目的.
