CAN总线在分布式温度监测系统中的应用

Application of CAN Bus in an Distributed Temperature Monitoring System

随着网络技术和总线技术的不断发展,控制系统规模的不断扩大,现场温度数据采集与控制逐渐呈现网络化、远距离的特点。针对传统的控制系统不能实现管控一体化以及所采集数据不能被长期存储、打印等问题,文章介绍了一种基于CAN总线的分布式温度监测系统,采用集中管理、分布监测的两层控制策略,给出了该系统的结构和软硬件设计方法与实现。该系统具有可靠性好、通信速率高、抗干扰能力强等特点。

In this paper, the CAN Bus technology principle and the merit are elaborated, and one kind of distributed temperature monitoring system based on CAN Bus is introduced. This system structure and the software and hardware design method and the realization have been produced. This system has good reliability, high correspondence speed, strong anti-jamming ability and so on.
