CAN总线系统中可控制现场智能节点设计

Design of Controllable Fields Intelligent Node in the CAN Bus System

CAN(Control Area Network)总线技术是一种支持分布式实时控制的高安全性的串行总线。本文对CAN控制网络中重要的现场设备--智能节点的具体实现进行的研究,主要包括智能节点的软件流程设计。该软件流程采用了模块化设计方法,本文主要介绍了以下几个重要部分:CAN总线通信程序,显示及键盘输入程序,控制算法程序等。

CAN bus technology is a serial bus with high security. It supports the distributed real-time control. The software design of the CAN intelligent node, one of the most important field instruments in the CAN control network, is introduced and implemented in this paper. It is designed by the means of module method and mainly consists of several parts, namely CAN bus communication program, display and keyboard input program, control algorithm program.
