CAN总线通信网络智能节点的软硬件设计

Hardware and Software Design of CAN Bus Communication Network Intelligent Node

设计了一种通信网络节点控制系统,整体组成包括总线收发器、总线控制器和微处理器控制系统。系统基于成熟的CAN总线技术,智能节点以单片机为控制核心作为微处理器控制系统,能够采集和存储数据,并通过总线控制器和收发器与上位机DSP相联系,进行数据的传输。控制器与收发器之间进行光电隔离,能够抑制干扰,运行稳定可靠。

This paper designs a communication network node control system, which includes bus transceiver, bus controller and micro- processor control system. Based on CAN bus technology, the microprocessor control system controlled by single-chip microcomputer can collect and store data, and contact with the host computer DSP through the bus controller and transceiver to complete data transmission. The photoelectric isolation between the controller and transceiver can suppress the interference and keep stable and reliable operation.
