摘要
CAN (Controller Area Network)总线属于现场总线 (field Bus)的范畴。介绍一种基于 CAN总线的网络监控系统方案。该系统由上位机 (PC机 )、下位机 (单片机 F0 4 0 )组成 ,采用 CAN卡和单片机本身集成的 CAN模块作为上、下位机通讯接口。上位机与 CAN卡的接口采用 VB编写 ,本文还给出了单片机中 CAN模块通信的数据处理方法。
CAN(Controller Area Network)Bus belongs to field Bus. This article includes a network supervise system based on CAN Bus. The system consists of PC and single chip processor(F040). This method uses CAN card and CAN model in single chip Processor(F040) as communication interface between PC and single chip processor(F040). Communication interface between PC and CAN card is realized by VB. This article introduces communication data process of CAN model in single chip processor(F040).
